BeschreibungDer Datensatz beinhaltet die Messergebnisse der Zählstellen für den motorisierten Individualverkehr auf Kantonsstrassen im Kanton Thurgau auf Stundenbasis.Verkehrszähler sind Teil des Verkehrsmonitorings und beinhalten die Datenerfassung an ausgewählten Strassenquerschnitten auf Kantonsstrassen sowie die Datenübertragung zu den Datenverarbeitungsstellen. Nutzendende der Verkehrsdaten sind unter anderem das Verkehrsmanagement und die Verkehrsstatistik.DatenbezugAus Kostengründen können nur die Werte der letzten zwei Wochen direkt von data.tg.ch bezogen werden. Alle anderen Daten - hier für das Jahr 2024 - können auf Jahresbasis über folgenden Link heruntergeladen werden:[https://ogdtg.ch/verkehrsdaten/total/2024_data.csv.gz](https://ogdtg.ch/verkehrsdaten/fahrzeugklassen/2024_fzkl_data.csv.gz)Die Daten sind verfügbar bis ins Jahr 2011 und die Link Struktur ist dabei jeweils gleich: [https://ogdtg.ch/verkehrsdaten/total/[JAHR]_data.csv.gz.](https://ogdtg.ch/verkehrsdaten/fahrzeugklassen/[JAHR]_fzkl_data.csv.gz.)Die Daten für das Jahr 2023 können also zum Beispiel über folgenden Link bezogen werden: [https://ogdtg.ch/verkehrsdaten/total/2023_data.csv.gz](https://ogdtg.ch/verkehrsdaten/total/2023_data.csv.gz)[](https://ogdtg.ch/verkehrsdaten/fahrzeugklassen/2023_fzkl_data.csv.gz)Hinweise zur NutzungBei der Nutzung der Daten ist zu beachten das lediglich die Daten bis zum letzten abgeschlossenen Jahr validiert sind. Bei den Daten des aktuell laufenden Jahres handelt es sich um Rohdaten, welche zum Ende des Jahres validiert werden.Beachten Sie bei der Interpretation der Daten bitte auch eventuell vorliegende Verkehrsbehinderungen auf der entsprechenden Strasse, welche die Zählung beeinflussen können. Aktuelle Hinweise zu Verkehrsbehinderungen finden Sie hier:[https://tiefbauamt.tg.ch/publikationen-zum-verkehr/baustellen/verkehrsbehinderungen.html/4343](https://tiefbauamt.tg.ch/publikationen-zum-verkehr/baustellen/verkehrsbehinderungen.html/4343)Die Zählstellen sind auf MET eingestellt (Spalten zeit_von und zeit_bis), d.h. die Zeitumstellung wird wie in Mitteleuropa ausgeführt. Bei der Umstellung von Winter- auf Sommerzeit fehlt die Stunde der Umstellung, dieser Tag hat dann 23 Stunden. Bei der Umstellung von Sommer- auf Winterzeit ist eine Stunde zu viel enthalten (der Tag hat dann 25 Stunden), die Stunde der Umstellung ist dann doppelt, aber mit unterschiedlichen Verkehrsdaten (da die gleiche Stunde zweimal durchlaufen wird).Auf [map.geo.tg.ch](https://map.geo.tg.ch/apps/mf-geoadmin3/?lang=de&topic=ech&time=2020&layers=strassenverkehrszaehlung_messdaten&layers_timestamp=20200101&E=2723900.00&N=1269850.00&zoom=0) sind alle permanenten Messstellen inkl. einer Jahresübersicht zum Durchschnittlichen Täglichen Verkehr (DTV) dargestellt.Die Daten des laufenden Jahres sind nicht plausibilisiert, es besteht kein Anspruch auf

en: The upgrade of the 3rd generation synchrotrons to diffraction-limited storage rings will enable a gain of up to two orders of magnitude in brilliance and further enable the creation of multiple macromolecular crystallography (MX) beamlines capable of delivering fluxes in excess of 1x10^15 photons·s−1; here called extremely high flux (EHF) MX beamlines. These beamlines, such as ID29, ESRF-EBS, BioCARS, APS-U, and MicroMAX, MAX IV, have all either been partly or solely geared toward delivering time-resolved MX experiments at room temperature and realising microsecond time resolutions. Given the uncharted territory of using dose rates in excess of 50 GGy·s−1 at many facilities, this article has examined some of the expected consequences suggesting that considerable attention should be paid to beam heating effects for < 20 μm crystals exposed to 1x10^15 photons·s−1. Several strategies have been proposed to mitigate heating effects when high dose rates are required for a time-resolved experiment, including reducing the absorbed dose by increasing the size of the crystal and the beam profile and explicitly exploiting the motion of the crystal in serial crystallography delivery systems. The model presented here is intended to serve as a useful tool to inform experimental design and support users’ decision-making in such cases.

en: Energy flows among coupled subsystems are essential for ultrafast dynamics and high-speed technologies. In magnetic materials, spin fluctuations -magnons- mediate these flows in ultrafast magnetism. Yet momentum-resolved access to low-energy magnons governing the microscopic dynamics has been lacking. Using time-resolved resonant diffuse scattering alongside complementary time-resolved X-ray techniques and quantum-kinetic simulations, we unveil the hierarchical energy pathways among correlated systems in the photoexcited antiferromagnet CuO. Above-bandgap excitation triggers near-instantaneous spin disorder, generating non-thermal magnons throughout reciprocal space within femtoseconds. Real-time momentum-resolved tracking reveals picosecond magnon quasi-thermalization, followed by nanosecond recovery via momentum-selective magnon-phonon scattering. The quasiparticle dispersion mismatch creates recovery bottlenecks that control non-equilibrium lifetimes. This microscopic framework transcends phenomenological models and generalizes across materials, establishing design principles for ultrafast control of material properties.

en: The goal of this proposal is to explore the competition between electron and energy transfer from photoexcited tryptophan to the heme group in ferrous and ferric Cytochrome c in physiological media. Cyt c contains only one tryptophan amino-acid residue, whose decay is still debated. While previous works alluded to an energy transfer, our recent experimental and theoretical studies raise the question of a competing electron transfer process, possibly simultaneous to a back-electron transfer in a Dexter process. This question can be resolved by monitoring the response of the central iron atom via femtosecond X-ray emission and X-ray absorptions, only possible due to the high peak brightness and short pulse duration of x-ray FELs.

The extinct plant group Bennettitales (Cycadeoidales) was a prominent part of Mesozoic vegetation. The group has been studied extensively and for more than 100 years it has been central in discussions of the relationships among the major groups of seed plants in which extinct plants were also considered. Despite much effort the phylogenetic position of the Bennettitales is still unresolved with a major obstacle being uncertainty about how to interpret the organisation and structure of the seed. The most widely accepted interpretation has been that the seed, like the seeds of most conifers, has a single integument around the nucellus and lacks any additional coverings. An alternative interpretation is that the seed integument is surrounded by an envelope comparable to the situation in extant Gnetales and extinct Erdtmanithecales. The petrified seed cone of Cycadeoidea (Bennettites) morierei described in the late nineteenth century from the Early Cretaceous of Normandy is one of the most informative bennettitalean reproductive structures with its superb preservation offering great potential for resolving the unsettled discussion regarding seed structure in Bennettitales.
	C. morierei was carefully documented by Octave Lignier in his monumental study “Végétaux fossiles de Normandie. Structure et affinités du Bennettites morierei Sap. & Mar. (sp.)” from 1894, but despite his meticulous analysis of the fossil, Lignier left certain questions open in his interpretation and in his widely cited reconstruction of the structure of the seed. In the paper associated with the datasets provided here we have re-examined fragments of Cycadeoidea morierei using synchrotron X-ray tomographic microscopy (SRXTM) to attempt to answer some of these open questions.
	Cycadeoidea morierei is based on a single petrified seed cone. The specimen was fractured by Lignier, who prepared several thin sections, in longitudinal as well as transverse directions in preparing his account. The original material was stored at the University of Caen, France, but most was lost during the second World War. However, several larger and smaller fragments of the seed cone were later recovered at the university and made available for the present study. Among the fragments studied using SRXTM were small isolated, abraded seeds and interseminal scales (e.g., fragments 6 and 8) and a few small groups of fractured seeds and interseminal scales still tightly packed together (e.g., fragment 17). Typically, these small fragments are broken at the base and only rarely are remains of the seed stalk preserved. One larger fragment (fragment 24) consists of several seeds with seed stalks intact. For comparison with Cycadeoidea morierei we also examined a fragment of another classic petrified seed cone, Cycadeoidea gibsoniana from the Early Cretaceous of isle of Wight, Southern England, using SRXTM. The results, combined with a comparative survey of other fossil material, indicate that the seeds of Bennettitales had at least one, perhaps two, envelopes covering the integument, comparable to what is seen among extant Gnetales, extinct Erdtmanithecales, and diverse fossil seeds recovered from Early Cretaceous mesofossil assemblages. Most of the SRXTM analyses of the Cycadeoidea material were carried during 2009-2023 on the TOMCAT beamline, SLS, Paul Scherrer Institute, Villigen, Switzerland. Fragment 24 was analysed at the new I-TOMCAT beamline at SLS in November 2025.

en: We investigated field electron emission from graphene on SiO₂/Si substrate. Graphene layer was structured into wire-shaped patterns with widths down to five microns using photolithography and etching. Field emission characteristics were measured using a scanning anode setup, wherein a sharp metal needle was positioned approximately 10 microns above the substrate and scanned across the graphene wires. Emission from the cleaved edges of the graphene wires was also examined. We observed electron emission primarily near the graphene edges, suggesting that the atomically thin structure and edge geometry of suspended graphene make it a promising candidate for high-brightness electron sources.

en: Varying the chemical consistency of acoustically levitated droplets opens up an in situ study of chemical and biochemical reactions in small volumes. However, the optimization of the mixing time and the minimization of the positional instability induced by solution dispensing are necessary for practical applications such as the study of the transient state of macromolecules crystallography during the ligand binding processes. For this purpose, we study the inertial mixing in a configuration compatible with the room-temperature crystallography using the acoustic levitation diffractometer, therein solution drops ejected at high velocity collide and coalesce with droplets dispensed on acoustically levitated and rotating polymer thin-film sample holders. With the proposed method, we are able to achieve the mixing time of ∼0.1 s for sub-micro and a few microliter droplets. The observed short mixing time is ascribed to the rapid penetration of the solution into the droplets and confirmed by a computational fluid dynamic simulation. The demonstrated accelerated solution mixing is tested in a pilot time-lapse protein crystallography experiment using the acoustic levitation diffractometer. The results indicate the detection of transient ligand binding state within 2 s after the solution dispensing, suggesting the feasibility of the proposed method for studying slow biochemical processes.

en: The controlled rotation of acoustically levitated samples is beneficial for analyzing sample properties, e.g., in a recently reported room temperature x-ray diffraction experiment, wherein thin film sample holders comprising thin film disks with short blades attached around their circumference were utilized. However, the mechanism of producing the torque and the determinant factor of the rotation direction for these planar ultrasonic rotors have been elusive. We, therefore, study the impact of the size and shape on the rotation characteristics of these ultrasonic rotors in air and further study the influence of the viscosity of fluid. Theory and experiment demonstrate the essential role of the short blades in producing the acoustic torque both in air and water. In the airborne case, the shape and arrangement of the blades are found to determine the rotation direction. In water, with a dynamic viscosity 55 times higher than that of air, we demonstrate that ultrasonic rotors down to 25-um-disk-diameter function in an optimized experimental geometry with approximately the same actuation efficiency as in air. Our results will be beneficial to further improve the applicability of the ultrasonic rotors as sample holders for airborne experiments and to explore the micrometer-scale ultrasonic rotors in liquid.

en: The transverse structure of field-emission electron wave packets is governed by cathode material and geometry through the near-apex electrostatic potential, which induces electrostatic defocusing and spatial transmission filtering. To study these effects, we develop a framework for field-emission wave-packet propagation that combines finite-element electrostatic potentials with paraxial Schroedinger propagation under an effective parabolic transverse-potential approximation, together with barrier-side spatial filtering. Applied to nanometer-scale prolate hemispheroidal emitters, the method enables efficient wave-packet calculations that reproduce the expected electron-optical defocusing and show how tunneling-induced narrowing can amplify subsequent transverse expansion. We further apply the framework to a two-dimensional film-edge model of a graphene edge emitter, where the Angstrom-scale initial width leads to stronger transverse expansion. The resulting wave packets are then used to study coherent multi-site superposition, predicting either overall beam narrowing or fragmentation into multiple beamlets, which may contribute to the striated field-emission-microscopy patterns reported for graphene edges.

en: Historical motion-picture films can become brittle, warped, shrunken, or fused, rendering them unreadable by conventional scanners because they can no longer be safely unrolled or transported under tension. X-ray tomography has already transformed the study of fragile cultural artifacts, including rolled medieval scrolls and the Herculaneum papyri. Similarly, we intend to measure rolled black and white motion-picture film by exploiting the strong X-ray absorption of the silver image layer at the TOMCAT beamline to investigate feasibility. Synchrotron hard X-ray tomography is attractive because it combines high flux, a parallel beam, and phase sensitivity. This enables fast scans with high signal-to-noise ratio, while phase contrast can enhance film boundaries and residual emulsion structures.

en: In the associate article to these data sets, we present an X-ray tomographic imaging method that is well suited for pulmonary disease studies in animal models, to resolve the full pathway from gas intake to gas exchange. Current state-of-the-art synchrotron-based tomographic phase-contrast imaging methods allow for three-dimensional microscopic imaging data to be acquired non-destructively in scan times of the order of seconds with good soft tissue contrast. However, when studying multi-scale hierarchically structured objects, such as the mammalian lung, the overall sample size typically exceeds the field of view illuminated by the X-rays in a single scan, and the necessity for achieving a high spatial resolution conflicts with the need to image the whole sample. Several image-stitching and calibration techniques to achieve extended high-resolution fields of view have been reported, but those approaches tend to fail when imaging non-stable samples, thus precluding tomographic measurements of large biological samples, which are prone to degradation and motion during extended scan times. In this work, we demonstrate a full-volume three-dimensional reconstruction of an intact rat lung under immediate post mortem conditions and at an isotropic voxel size of (2.75 µm)^3. We present the methodology for collecting multiple local tomographies with 360 degree extended field of view scans followed by locally non-rigid volumetric stitching. Applied to the lung, it allows to resolve the entire pulmonary structure from the trachea down to the parenchyma in a single dataset.

en: Long-wavelength pulses from the Swiss X-ray free-electron laser (XFEL) have been used for de novo protein structure determination by native single-wavelength anomalous diffraction (native-SAD) phasing of serial femtosecond crystallography (SFX) data. In this work, sensitive anomalous data-quality indicators and model proteins were used to quantify improvements in native-SAD at XFELs such as utilization of longer wavelengths, careful experimental geometry optimization, and better post-refinement and partiality correction. Compared with studies using shorter wavelengths at other XFELs and older software versions, up to one order of magnitude reduction in the required number of indexed images for native-SAD was achieved, hence lowering sample consumption and beam-time requirements significantly. Improved data quality and higher anomalous signal facilitate so-far underutilized de novo structure determination of challenging proteins at XFELs. Improvements presented in this work can be used in other types of SFX experiments that require accurate measurements of weak signals, for example time-resolved studies.

The method is applied to several alumina washcoats with different particle size distributions deposited on a cordierite substrate. The results bring new insights into the drying dynamics of the porous filter wall as well as the on-wall catalyst layer, including the process of layer shrinking and cracking. The XRT results are supplemented by cross-section scanning electron microscopy images and mercury intrusion porosimetry of the final structures. In addition to the statistical analysis of the washcoat distribution, the impact of the washcoat structure on filter pressure loss is determined by  experiments.

en: In the related publication to these data sets, we explore the flow dynamics for two-phase flow in a porous medium (a bioclastic carbonate rock). We use state-of-the-art synchrotron X-ray tomography to capture the fluid dynamics within the pore space, with a scan time of 1 second and a temporal resolution (scan repetition rate) of 2 s. The rock sample was initially saturated with brine (DI water doped with 15%wt. KI) before brine and nitrogen gas were injected simultaneously. As the gas establishes a path through the pore space, the flow dynamics are transient. Eventually, an equilibrium is established, where the gas saturation oscillates about a constant mean value; this is referred to as steady state. There are 5 data sets, 3 of which capture the unsteady state dynamics, and 2 of which capture the steady state dynamics. The images were captured with a voxel size of 2.75 µm3. In these data sets we observe that the pore scale dynamics evolve as the macroscopic flow transitions from unsteady state to steady state. We observe that the saturation of the gas plateaus out before the differential pressure across the core. This suggests that gas phase is more mobile during unsteady state.

We report a soft x-ray resonant magnetic scattering study of the spin configuration in multiferroic thin
films of Co0.975Ge0.025Cr2O4 (Ge-CCO) and CoCr2O4 (CCO) under low and high magnetic fields from 0.2 to
6.5 T. A characterization of Ge-CCO at a low magnetic field was performed, and the results were compared with
those of pure CCO. The ferrimagnetic phase transition temperature TC ≈ 95 K and the multiferroic transition
temperature TS ≈ 27 K in Ge-CCO are comparable with those observed in CCO. In Ge-CCO, the ordering wave
vector (qq0) observed below TS is slightly larger compared with that of CCO, and unlike CCO, the diffraction
intensity consists of two contributions that show a dissimilar x-ray polarization dependence. In Ge-CCO, the
coercive field observed at low temperatures was larger than the one reported for CCO. In both compounds,
an unexpected reversal of the spiral helicity, and therefore the electric polarization, was observed on simply
magnetic field cooling. In addition, we find a change in the helicity as a function of momentum transfer in the
magnetic diffraction peak of Ge-CCO, indicative of the presence of multiple magnetic spirals.

We find long-ranged ordered Supercells of 106/107 unit cells of unstrained STO/LSAT, caused by complete lattice relaxation through high-temperature annealing. Transmission electron microscopy (TEM) images show that this periodicity is based on line dislocations at the interface region. The presence of such ordered Superstructures in such widely used complex oxides sets the ideal conditions for Moiré-tuned interfacial electronic modifications and ferroelectric Super-crystallinity, opening up the possibility for novel interface functionalities and impacting findings on vortex structured multilayers systems.

en: Myelin insulates neuronal axons and enables fast signal transmission, constituting a key component of brain development, aging and disease. Yet, myelin-specific imaging of macroscopic samples remains a challenge. Here, we exploit myelin’s nanostructural periodicity, and use small-angle X-ray scattering tensor tomography (SAXS-TT) to simultaneously quantify myelin levels, nanostructural integrity and axon orientations in nervous tissue. Proof-of-principle is demonstrated in whole mouse brain, mouse spinal cord and human white and gray matter samples. Outcomes are validated by 2D/3D histology and compared to MRI measurements sensitive to myelin and axon orientations. Specificity to nanostructure is exemplified by concomitantly imaging different myelin types with distinct periodicities. Finally, we illustrate the method’s sensitivity towards myelin-related diseases by quantifying myelin alterations in dysmyelinated mouse brain. This non-destructive, stain-free molecular imaging approach enables quantitative studies of myelination within and across samples during development, aging, disease and treatment, and is applicable to other ordered biomolecules or nanostructures.

In the original article associated with this dataset, we present synchrotron radiation-based X-ray phase-contrast imaging (X-PCI) as an efficient and non-destructive imaging technique to provide high resolution, three-dimensional (3D) information on myocardial microstructure in left ventricular hypertrophy. In the pilot study, the methodology was applied on tissue samples obtained from three patients that underwent septal myectomy. This technique allows for multi-scale investigation - to localize regions of interest, low resolution overlapping scans, at 5.8um effective pixel size, were achieved to cover the entire sample, whereas high resolution datasets, at 0.65 um pixel size, were collected locally allowing assessment of myocyte organization, 3D connective tissue distribution and vasculature.
X-PCI data was visualized and analyzed. 3D myocyte arrangement, interstitial fibrosis, collagen disarray, and vascular remodelling were identified and related to findings of non-invasive cardiac imaging. The integration of imaging data data illustrates the correspondence of macrostructural and functional non-invasive phenotypes with invasive microstructural phenotypes, suggesting the potential clinical utility of non-invasive myocardial deformation patterns in phenotyping left ventricular hypertrophy.

Particle accelerators are enabling tools for scientific exploration and discovery in various disciplines.  Finding optimized operation points for these complex machines is a challenging task, however, due to the large number of parameters involved and the underlying non-linear dynamics. Here, we introduce two families of data-driven surrogate models, based on deep and invertible neural networks, that can replace the expensive physics computer models.
These models are employed in multi-objective optimisations to find Pareto optimal operation points for two fundamentally different types of particle accelerators. Our approach reduces the time-to-solution for a multi-objective accelerator optimisation up to a factor of 640 and the computational cost up to 98%. The framework established here should pave the way for future on-line and real-time multi-objective optimisation of particle accelerators.

We present a detailed low-energy muon spin rotation and x-ray magnetic circular dichroism (XMCD) investigation of the magnetic structure in ultrathin tetragonal (T)-CuO films. The measured muon-spin polarization decay indicates an antiferromagnetic (AFM) order with a transition temperature higher than 200 K. The XMCD signal obtained around the Cu L2,3 edges indicates the presence of pinned Cu
2+ moments that are parallel to the sample surface, and additionally, isotropic paramagnetic moments. The pinning of some of the Cu moments is caused by an AFM ordering consisting of moments that lie most likely in plane of the film. Moreover, pinned moments show a larger orbital magnetic moment contribution with an approximate ratio of m_orb/m_spin=1.5, indicating that these spins are located at sites with reduced symmetry. Some fractions of the pinned moments remain pinned from an AFM background even at 360 K, indicating that TN>360K. We propose a simple model that explains these experimental findings, showing that the magnetic order of the T-CuO ultrathin films differs from the theoretical predictions.

en: The associated article to these datasets describes a new genus and species, Skyttegaardia galtieri E.M.Friis, P.R.Crane & E.M.Friis. The fossils were isolated from dark clay of the early-mid Berriasian Skyttegård Member of the Rabekke Formation, collected at the Skyttegård and Arnager Bay localities, Bornholm, Denmark. The fossils were studied using SEM. Internal structures of the fossils were also investigated using synchrotron radiation X-ray tomographic microscopy at the TOMCAT Beamline, Swiss Light Source, Paul Scherrer Institute, Villigen, Switzerland. The new taxon is based on small microsporangiophores consisting of a proximal fertile portion and a distal sterile extension. The fertile portion is stalk-like with two sporangia deeply sunken into two cavities in the presumed abaxial surface. The sterile distal tip is long, horn-shaped and tapers to a slender point. Pollen grains in situ are of the Monosulcites/Cycadopites type, monocolpate, tectate-psilate. General organisation and details of epidermal features, as well as pollen morphology, are consistent with a possible relationship of Skyttegaardia galtieri to extant Cycadales. However, in the low number of partially embedded sporangia Skyttegaardia is distinct from the microsporophores of extant cycads, in which the sporangia are usually crowded on the surface of the microsporangiophores, typically in groups of two to five.

en: Quantum sensors and qubits are usually two-level systems (TLS), the quantum analogues of classical bits assuming binary values 0 or 1. They are useful to the extent to which superpositions of 0 and 1 persist despite a noisy environment. The standard prescription to avoid decoherence of solid-state qubits is their isolation by means of extreme dilution in ultrapure materials. We demonstrate a different strategy using the rare-earth insulator LiY1−xTbxF4 (x = 0.001) which realizes a dense random network of TLS. Some TLS belong to strongly interacting Tb3+ pairs whose quantum states, thanks to localization effects, form highly coherent qubits with 100-fold longer coherence times than single ions. Our understanding of the underlying decoherence mechanisms—and of their suppression—suggests that coherence in networks of dipolar coupled TLS can be enhanced rather than reduced by the interactions.

The insulating rare-earth magnet LiY1−xHoxF4 has received great attention because a laboratory field applied perpendicular to its crystallographic caxis converts the low-energy electronic spin Hamiltonian into the (dilute) transverse field Ising model. The mapping between the real magnet and the transverse field Ising model is strongly dependent on the exact nature of the low-energy Hamiltonian for the material, which can be determined by spectroscopy in the dilute limit. The energies of the eigenstates are in the difficult terahertz (THz) regime, and here we use THz time domain and Fourier transform spectroscopy to directly measure the lowest crystal-field levels of LiY1−xHoxF4 in the dilute limit, including nuclear hyperfine substructure. The high resolution of our measurements allows us to observe the nonequidistantly spaced Ho (I=72) hyperfine transitions originating from dipolar and quadrupolar hyperfine interactions. We provide refined crystal-field parameters and extract the dipolar and quadrupolar hyperfine constants AJ=0.02703$\pm$0.00003 cm−1 (810.3$\pm$0.9 MHz) and B=0.04$\pm$0.01 cm−1(1.2$\pm$0.3 GHz), respectively. Thereupon we determine all crystal-field energy levels and magnetic moments of the 5I8 ground-state manifold, including the (nonlinear) hyperfine corrections. The latter improve the prediction precision by a factor of 60 compared to previous crystal-field parameters. Additionally, we establish the far-infrared, low-temperature refractive index of LiY1−xHoxF4.

en: The article accompanying this dataset gives a brief overview of the recent developments of time-resolved X-ray tomography that have led to what we now call “tomoscopy”. A novel setup is presented and applied that pushes temporal resolution down to just 1 ms, i.e. 1000 tomograms per second (‘tps') are acquired, while maintaining spatial resolutions of micrometres and running experiments for minutes without interruption. Applications recorded at different acquisition rates ranging from 50 to 1000 tps are presented. We observe and quantify the immiscible hypermonotectic reaction of AlBi10 (in wt%) alloy and dendrite evolution in AlGe10 (in wt%) casting alloy during fast solidification. We analyse the combustion process and the evolution of the constituents in a burning sparkler. Finally, we follow the structure and density of two metal foams over a long period of time and derive details of bubble formation and bubble ageing including quantitative analyses of bubble parameters with millisecond temporal resolution.

en: The associated article to these datasets describes a new genus and two new species from the Late Cretaceous (Campanian-Maastrichtian) Mira locality, District of Coimbra, Portugal. The new taxa are based on small lignitized and charcoalified flower buds, post-anthetic flowers and a fruit. Internal structures of the fossils were investigated using synchrotron radiation X-ray tomographic microscopy at the TOMCAT Beamline, Swiss Light Source, Paul Scherrer Institute, Villigen, Switzerland. Internal structures and other details provide clear evidence for a phylogenetic position of the fossils in the family Primulaceae of the order Ericales. A key distinctive feature that is critical for placing the fossils in the Primulaceae s. l., is the free, central dome-shaped placenta that bears numerous, densely spaced ovules. The fruit matured into a capsule containing many, minute, reticulate seeds. Phylogenetic analyses using external and internal features of the fossils confirm their relationship to Primulaceae s. l. and indicate a position as sister to the genus Samolus of the subfamily Theophrastoideae. The occurrence of these fossils in the Late Cretaceous calls into question a previous hypothesis that the Theophrastoideae originated in the Neotropics and dispersed relatively recently into other regions.

Ptychographic hard X-ray computed tomography (PXCT) is a recent method allowing imaging with quantitative electron-density contrast. Here, we imaged at cryogenic temperature and without sectioning, cellular and subcellular structures of a chemically-fixed and stained wild-type mouse retina (tomogram 1), including axons and synapses with complete isotropic 3D information over tens of microns. Comparison with tomograms of degenerative retina from a mouse model of retinitis pigmentosa (tomogram 2) illustrates the potential of this method for analysing disease processes like neurodegeneration at sub-200 nm resolution.

As a non-destructive imaging method, PXCT is very suitable for correlative imaging. Within the outer plexiform layer containing the photoreceptors synapses, we identified somatic synapses. We used a small region inside the X-ray-imaged sample for further high-resolution focused ion beam / scanning electron microscope (FIB/SEM) tomography (tomogram 3). The subcellular structures of synapses obtained with the X-ray technique matched the EM data demonstrating that PXCT is a powerful scanning method for tissue volumes of more than 60 cells and sensitive enough for identification of regions as small as 200 nm, remaining available for further structural and biochemical investigations.

en: We present a theoretical framework to model the generation and shaping of carrier-envelope phase stable narrowband pulses by means of difference frequency generation from independently tunable optical parametric amplifiers. The simulations apply group delay dispersion (GDD) to infrared (IR) pulses to generate second-order phase-modulated mid-IR pulses. The modulation of the second-order phase of the mid-IR is dependent on the relative second-order phase of the mixed IR pulses. Changing the relative second-order phase can produce linearly chirped or Fourier-limited narrowband mid-IR pulses. The bandwidth of the mid-IR is dependent on the pulse-shaped IR pulses and the central frequency of the mid-IR pulses are unaffected by the chirp. The delay between the optical parametric amplifiers offers another degree of tunability. The introduction of a delay changes the central frequency of the generated mid-IR pulse. It also has limited impact on the bandwidth of the mid-IR and does not change the dependence of the second-order phase of the mid-IR on the relative second-order phase of the IR pulses.

Circular dichroism observed by resonant x-ray diffraction at the Cu L3 edge was investigated in a chiral antiferromagnet, Pb(TiO)Cu4(PO4)4, which shows magnetic quadrupole order (TN = 7K). At temperatures
above TN, space-group-forbidden reflection 100 is observed due to the anisotropic tensor of susceptibility (ATS) scattering. With decreasing temperature, the reflection intensity shows substantial circular dichroism below
TN. We found one-to-one correspondence between the sign of the circular dichroism and that of the sample’s crystallographic chirality. In addition, the reflection intensity depends on the product of poling magnetic and
electric fields. The circular dichroism observed in this study is interpreted as the interference between the ATS and the magnetic scatterings. This finding shows that the interference scattering probes both the chirality and the
order parameter of the magnetic quadrupole order in this chiral antiferromagnetic.

en: Understanding ultrafast magnetization dynamics on the microscopic level is of strong current interest due to the potential for applications in information storage. In recent years, the spin-lattice coupling has been recognized to be essential for ultrafast magnetization dynamics. Magnetoelectric multiferroics of type II possess intrinsic correlations among magnetic sublattices and electric polarization (P) through spin-lattice coupling, enabling fundamentally coupled dynamics between spins and lattice. Here we report on ultrafast magnetization dynamics in a room-temperature multiferroic hexaferrite possessing ferrimagnetic and antiferromagnetic sublattices, revealed by time-resolved resonant x-ray diffraction. A femtosecond above-bandgap excitation triggers a coherent magnon in which the two magnetic sublattices entangle and give rise to a transient modulation of P. A novel microscopic mechanism for triggering the coherent magnon in this ferrimagnetic insulator based on the spin-lattice coupling is proposed. Our finding opens up a novel but general pathway for ultrafast control of magnetism.

en: Chloride transport by microbial rhodopsins is an essential process of which the molecular details have remained elusive, such as the mechanisms that convert light energy to drive ion pumping and ensure the unidirectionality of the transport. We combined time-resolved serial crystallography with time-resolved spectroscopy and multiscale simulations to elucidate the molecular mechanism of a chloride pumping rhodopsin and the structural dynamics throughout the transport cycle. We traced transient anion binding sites, obtained evidence for how light energy is used in the pumping mechanism, and identified steric and electrostatic molecular gates ensuring unidirectional transport. An interaction with the π-electron system of the retinal supports transient chloride ion binding across a major bottleneck in the transport pathway. These results allow us to propose key mechanistic features enabling finely controlled chloride transport across the cell membrane in this light powered chloride ion pump.

Understanding the spatial extend and geometric aspects of these mechanisms will contribute to the technological exploitation of these phenomena.

We report on element-resolved ultrafast magnetization dynamics in multiferroic CoCr2O4 and
Co0.975Ge0.025Cr2O4 after optical excitation above the electronic band gap. We observe demagnetization dynamics
in the range of several picoseconds, up to two orders of magnitude faster than previously reported
demagnetization in other ferrimagnetic insulators. Moreover, we find that the dynamics of the two magnetic
ions differ significantly just below the Curie point. The dynamics of the low-temperature multiferroic phase
are almost two times slower than those in the ferrimagnetic phase. This suggests that the additional magnetic
cycloidal component, which is coupled to electric polarization at low temperatures, might influence the ultrafast
magnetization dynamics.

The fossil seeds of Aristospermum are from the Early Cretaceous Buarcos, Catefica and Vale de Água mesofossil floras of Portugal (Aptian-early Albian) and the Puddledock mesofossil flora of Puddledock, Virginia, North America (early-middle Albian). The fossil seeds of Siratospermum are from the mid Cretaceous (early Cenomanian) Mauldin Mountain mesofossil flora. The fossils were studied for morphological and anatomical features using scanning electron microscopy (SEM) and synchrotron radiation X-ray tomographic microscopy (SRXTM). The seeds are anatropous, bitegmic and endostomic with the micropyle formed by the inner integument. The seed coat in all specimens consists of an exotesta of varied thickness, an endotesta of crystal cells and a three-layered tegmen with crossed fibers, features that in extant angiosperms define seeds of Aristolochiaceae (subfamilies Asaroideae and Aristolochioideae) and the fossils document for the first time the presence of the Aristolochiaceae lineage already by the Early Cretaceous.

Here we report a resonant x-ray diffraction (RXD) study at the Cu L3 edge on the multichiral system CsCuCl3, exhibiting helical magnetic order in a chiral crystal structure. RXD is a powerful technique to disentangle electronic degrees of freedom due to its sensitivity to electric monopoles (charge), magnetic dipoles (spin),
and electric quadrupoles (orbital). We characterize electric quadrupole moments around Cu ascribed to the unoccupied Cu 3d orbital, whose quantization axis is off the basal plane. Detailed investigation of magnetic reflections reveals additional sinusoidal modulations along the principal axis superimposed on the reported
helical structure, i.e., a longitudinal conical (helical-butterfly) structure. The out-of-plane modulations imply significant spin-orbit interaction despite S = 1/2 of Cu2+.

Drying of water from porous structures investigated by time-resolved X-ray tomography

In this contribution, we apply time-resolved X-ray tomography to study drying of water in porous ceramic substrates used in emission control technologies. A time resolution of 2 seconds is achieved, and allows to observe the spatiotemporal distribution of water in structured porous materials. An image processing framework based on machine learning is introduced to track pore emptying and filling in a large number of 3D scans. Drying curves are extracted from the tomographic data to investigate drying in materials with different structural properties. Water redistribution by capillary pumping and rapid pore emptying by Haines jumps are observed, and their impact on drying dynamics is discussed. The relationship between the evolution of water clusters and different drying regimes is established. The obtained information on the interplay between pore emptying, water redistribution and the size of water clusters provides an important link between the structural properties of dried materials and their drying rate.

X-ray linear dichroism and X-ray birefringence microscopy are yet to be fully utilized as instruments in the microstructural characterization of crystalline materials. These datasets are obtained from the first demonstration of analyzer-free X-ray linear dichroism microscopy using spectroscopic hard X-ray ptychography. Analysis of these data enabled a spectroscopic and microstructural characterization of polycrystalline vanadium pentoxide on the nanoscale, outside of diffraction-contrast based methods.

The performance of functional materials is either driven or limited by nanoscopic heterogeneities distributed throughout the material’s volume. To better our understanding of these materials, we need characterization tools that allow us to determine the nature and distribution of these heterogeneities in their native geometry in 3D. These datasets contain measurements of pristine and industrially used vanadium phosphorous oxide (VPO) catalysts. The experiments were conducted using combined method of x-ray near-edge spectroscopy, ptychographic x-ray computed nanotomography, and sparsity techniques. The method allows the acquisition of quantitative multimodal tomograms of representative sample volumes at sub–30 nm half-period spatial resolution within practical acquisition times, which enables local structure refinements in complex geometries.

en: The associated article to this dataset describes a new genus and species, Renbernia zhoui E.M.Friis, P.R.Crane & K.R.Pedersen from the Early Cretaceous (early-middle Albian) mesofossil flora collected in Potomac Group sediments at the Puddledock locality, Virginia, U.S.A. The new taxon is based on microsporangiate structures with Decussosporites-type pollen in situ in densely arranged microsporangiophores. The microsporangia are elongate with extrorse and valvate dehiscence. Synchrotron radiation X-ray tomographic microscopy shows that they are bisporangiate. The in situ Decussosporites-type pollen is elliptical with an unusual arrangement of apertures. On the presumed distal face there is a long median colpus flanked laterally by two equally long lateral colpi. On the presumed proximal side there is a short transverse colpus perpendicular to the longitudinal colpi. Renbernia zhoui is compared to Brenneria potomacensis, another microsporangiate structure from the Potomac Group sediments with Decussosporites-type pollen in situ. B. potomacensis is slightly older than Renbernia zhoui and is distinguished by the more rounded microsporangia and the pollen is more distinctly saccate. A comparison with the extinct pollen genus Eucommiidites and a possible link of Renbernia zhoui to the Bennettitales-Erdtmanithecales-Gnetales group, which is diverse and common in the Puddledock mesofossil flora, is discussed.

en: The recently discovered superconducting nickelates are already looking quite different to their cousins, the cuprates. One big reason is the magnetic order. First, the undoped parent compound NdNiO2 appears to be non-magnetic, unlike the undoped cuprates, which are antiferromagnetic. Secondly, the hole-doped Nd1-xSrxNiO2 seems to host antiferromagnetic order as well as superconductivity and these coexisting phenomena are rare in hole-doped cuprates. Low energy muon spin relaxation provides the ideal tool to probe the magnetism in this new family of superconductors.

en: Incomplete cancellation of collinear antiparallel spins gives rise to ferrimagnetism. Even if the oppositely polarized spins are owing to the equal number of a single magnetic element having the same valence state, in principle, a ferrimagnetic state can still arise from the crystallographic inequivalence of the host ions. However, experimental identification of such a state as “ferrimagnetic” is not straightforward because of the tiny magnitude expected for M and the requirement for a sophisticated technique to differentiate similar magnetic sites. We report a synchrotron-based x-ray investigation on an epitaxial film of CaFe2O4, which exhibits two magnetic phases with similar energies, performed at the Fe L2,3 edges. We find that while one phase of CaFe2O4 is antiferromagnetic, the other one is “ferrimagnetic” with an antiparallel arrangement of an equal number of spins between two distinct crystallographic sites with very similar local coordination environments. Our results further indicate two distinct origins of an overall minute M; one is intrinsic, from distinct Fe3+ sites, and the other one is extrinsic, arising from defective Fe2+ likely forming weakly-coupled ferrimagnetic clusters. These two origins are uncorrelated and have very different coercive fields. Hence, this work provides a direct experimental demonstration of “ferrimagnetism” solely due to crystallographic inequivalence of the Fe3+ as the origin of the weak M of CaFe2O4.

en: In the corresponding article to these data sets, we explore the flow dynamics for two-phase flow in a porous medium (a bioclastic carbonate rock). We use state-of-the-art synchrotron X-ray tomography to capture the fluid dynamics within the pore space, with a temporal resolution of 1 s. The rock sample was initially saturated with brine (DI water doped with 15%wt. KI) before brine and nitrogen gas were injected simultaneously. As the gas establishes a path through the pore space, the flow dynamics are transient. Eventually, an equilibrium is established, where the gas saturation oscillates about a constant mean value; this is referred to as steady state. There are 9 data sets, with all the dynamics captured during steady state. We explore 3 total flow rates (brine flow rate + nitrogen flow rate): 0.1ml/min, 0.4ml/min, 0.7ml/min. With 3 fractional flows (brine flow rate / total flow rate) explored for each total flow rate: 0.85, 0.7 and 0.5. The images were captured with a voxel size of 2.75 µm3. In these data sets we observe the development of intermittent flow pathways, and the stability of these pathways when perturbed by a change in the flow rate .

en: Understanding the ultrashort time scale structural dynamics of the FeRh metamagnetic phase transition is a key element in developing a complete explanation of the mechanism driving the evolution from an antiferromagnetic to ferromagnetic state. Using an X‐ray free electron laser we determine, with sub‐ps time resolution, the time evolution of the (–101) lattice diffraction peak following excitation using a 35 fs laser pulse. The dynamics at higher laser fluence indicates the existence of a transient lattice state distinct from the high temperature ferromagnetic phase. By extracting the lattice temperature and comparing it with values obtained in a quasi‐static diffraction measurement, we estimate the electron–phonon coupling in FeRh thin films as a function of laser excitation fluence. A model is presented which demonstrates that the transient state is paramagnetic and can be reached by a subset of the phonon bands. A complete description of the FeRh structural dynamics requires consideration of coupling strength variation across the phonon frequencies.

en: We present a detailed atomistic picture of the oxidation mechanism of Co nanoparticles and its impact on magnetism by experimentally following the evolution of the structure, chemical composition, and magnetism of individual, gas-phase grown Co nanoparticles during controlled oxidation. The early stage oxidation occurs in a two-step process characterized by (i) the initial formation of small CoO crystallites randomly distributed across the nanoparticle surface, until their coalescence leads to structural completion of the oxide shell and passivation of the metallic core; (ii) progressive conversion of the CoO shell to Co3O4, accompanied by void formation due to the nanoscale Kirkendall effect. The Co nanoparticles remain highly reactive toward oxygen during phase (i), demonstrating the absence of a pressure gap whereby a low reactivity at low pressures is postulated. Our results provide an important benchmark for an improved understanding of the magnetism of oxidized cobalt nanoparticles, with potential implications on their performance in catalytic reactions.

en: The concept of quasiparticles is a landmark of condensed matter physics. The symmetry of quasiparticles is of particular importance to attaining emergent phenomena in both equilibrium and nonequilibrium states. Whereas recent exploration has demonstrated chiral fermions and their relevance in emergent phenomena closely relating to topology, the experimental verification of chiral phonons (bosons) remains challenging despite their expected strong impact on fundamental physical properties. Here we show experimental proof of chiral phonons by means of resonant inelastic X-ray scattering with circularly polarized X rays. We show how intrinsically chiral circularly polarized X rays couple to circular phonons at different positions in reciprocal space, principally being able to determine the chiral dispersion of a lattice mode. Our experimental proof of chiral phonons demonstrates a new degree of freedom in condensed matter that is not only of fundamental importance but also of inspiring unconventional ideas to extract emergent phenomena.

en: In the associated article to these datasets, we describe a new genus and species of probable lauralean relationship, together with a new fossil related to Virginianthus from the Early Cretaceous Puddledock mesofossil flora from Virginia, USA. A further specimen is also described from the Early Cretaceous Drewry’s Bluff mesofossil flora, also collected in Virginia. The fossils are lignitized (PP56524, PP56559, PP57029) or charcoalified (PP54167, 57027, PP57673) and preserved in the preanthetic stage as floral buds. Internal details were studied using synchrotron radiation X-ray tomographic microscopy at the TOMCAT Beamline, Swiss Light Source, Paul Scherrer Institute, Villigen, Switzerland. The flower buds are small and delicate, preserved as lignitized and charcoalified specimens highly suitable for SRXTM. The new lauralean fossil is characterized by a tetramerous and whorled arrangement of floral parts with at least six whorls of perianth parts and two whorls of stamens. The perianth is inserted on the outside of a distinct floral cup (hypanthium) and on the rim of the hypanthium. The androecium is also borne on the rim of the hypanthium. The gynoecium consists of three carpels that are free from each other but fused to the inside of the hypanthium wall. Each carpel has many ovules borne along two ventral placentae. The Virginianthus-like fossil has floral organs in a distinct spiral arrangement on the rim of a distinct floral cup with about 12 perianth parts and numerous stamens and possibly staminodes. The new lauralean fossil shows a mosaic of features shared by several modern groups and cannot be placed unequivocally in any extant family or order, but the overall combination of features indicates a position among magnoliid angiosperms, probably close to the base of the Laurales. The Virginianthus-like fossil is more straightforward to place and appears closely related to the lauralean family Calycanthaceae.
