de: Auf den öffentlichen Gewässern in der Schweiz ist die Schifffahrt grundsätzlich erlaubt. Dieser Grundsatz ist im Bundesrecht verankert. Gleichzeitig unterstehen die Gewässer bezüglich der Schifffahrt den Kantonen, und diese dürfen bei wichtigen Gründen die Schifffahrt einschränken oder ganz untersagen. Die Signalisierung der Einschränkungen vor Ort erfolgt in der Regel mit Hilfe von Schifffahrtszeichen, die vom Bund festgelegt wurden.

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.

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: 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: 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.

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.

en: We identify a highly ordered Moiré lattice at the buried SrTiO3 (STO) - (La,Sr)(Al,Ta)-oxide (LSAT) interface by high-resolution X-ray diffraction reciprocal space mapping. 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.

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: 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.

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.

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.

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+.

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.

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: The binding and release of ligands from their protein targets is central to fundamental biological processes as well as to drug discovery. Photopharmacology introduces chemical triggers that allow the changing of ligand affinities and thus biological activity by light. Insight into the molecular mechanisms of photopharmacology is largely missing because the relevant transitions during the light-triggered reaction cannot be resolved by conventional structural biology. Using time-resolved serial crystallography at a synchrotron and X-ray free-electron laser, we have captured the release of azo-combretastatin A4 and the resulting conformational changes in tubulin. Nine structural snapshots from 1 ns to 100 ms complemented by simulations show how cis-to-trans isomerization of the azobenzene bond leads to a switch in ligand affinity, opening of an exit channel, and collapse of the binding pocket upon ligand release. The resulting global backbone rearrangements are related to the action mechanism of tubulin-binding drugs against gout, cancer, and COVID-19.

en: Vision is initiated by the rhodopsin family of light-sensitive G protein-coupled receptors (GPCRs). A photon is absorbed by the 11-cis retinal chromophore of rhodopsin which isomerises within 200 femtoseconds to the all-trans conformation, thereby initiating the cellular signal transduction processes that ultimately lead to vision. However, the intramolecular mechanism by which the photoactivated retinal induces the activation events inside rhodopsin remains elusive. In this work, we use ultrafast time-resolved crystallography at room temperature to determine how an isomerised twisted all-trans retinal stores the photon energy required to initiate protein conformational changes associated with the formation of the G protein-binding signalling state. The distorted retinal at 1 ps time-delay of photoactivation has pulled away from half of its numerous interactions with its binding pocket, and the excess of the photon energy is released through an anisotropic protein breathing motion in the direction of the extracellular space. Strikingly, the very early structural motions in the protein side chains of rhodopsin appear in regions involved in later stages of the conserved Class A GPCR activation mechanism. Our work sheds light on the earliest stages of vision in vertebrates and points to fundamental aspects of the molecular mechanisms of agonist-mediated GPCR activation.

en: Electromagnons are emergent collective excitations that involve both vibrational and magnetic characters, arising from strong coupling between the lattice and spins. Although previous experimental studies have successfully observed the spin dynamics of a coherent electromagnon, the associated atomic motions have not been directly observed. Here we use time-resolved hard X-ray diffraction to directly measure the ultrafast structural motion following the excitation of a coherent electromagnon by an intense THz pulse in a multiferroic hexaferrite. Comparing the dynamics of two different components, one striking outcome is the different phase shifts relative to the driving field, gives deeper insights into the excitation process of the electromagnons. The observation of combined lattice and magnetization dynamics of the electromagnon resonance paves the way to access the magnetoelectric coupling strength in ultrafast timescales, which remains a missing fundamental parameter for ultrafast control of magnetism in multiferroics.

en: We present a detailed study of the magnetic, spectroscopic and structural properties of ultrathin LaMnO3 films deposited on SrTiO3(001) substrates by oxide molecular beam epitaxy. We find that the as-grown LaMnO3 films are slightly reduced and present a significant magnetic moment, while annealing to 600 oC fully oxidises and enhances its magnetic properties. From synchrotron x-ray photoemission spectromicroscopy, we find the presence of Sr, Ca and Si in the LaMnO3 film that diffuse from the SrTiO3 substrate; these impurities act as hole dopants, and can explain the presence of ferromagnetism in LaMnO3. This work highlights the importance of cation mobility at the elevated growth temperature in modifying the magnetic properties of ultrathin LaMnO3 films.

en: Acoustic levitation has attracted attention in terms of chemical and biochemical analysis in combination with various analytical methods because of its unique container-less environment for samples that is not reliant on specific material characteristics. However, loading samples with very high viscosity is difficult. To expand the scope, we propose the use of polymer thin films as sample holders, whereby the sample is dispensed on a film that is subsequently loaded onto an acoustic levitator. When applied for protein crystallography experiments, rotation controllability and positional stability are important prerequisites. We therefore study the acoustic levitation and rotation of thin films with an aspect ratio (the diameter-to-thickness ratio) of 80–240, which is an order of magnitude larger than those reported previously. For films with empirically optimized shapes, we find that it is possible to control the rotation speed in the range of 1–4 rotations per second while maintaining a positional stability of 12 ± 5 µm. The acoustic radiation force acting on the films is found to be a factor of 26–30 higher than that for same-volume water droplets. We propose use cases of the developed films for protein crystallography experiments and demonstrate data collections for large single crystal samples at room temperature.

Ductal carcinoma in situ (DCIS) is a pre-invasive tumor that can give rise to invasive breast cancer, a
leading cause of cancer death. We generated a large-scale tissue microarray imaging dataset, stained for
chromatin using DAPI, from 560 tissue samples from 122 patients at 3 disease stages and 11 phenotypic
categories of the tumor during DCIS progression. We investigated what cell or tissue features mark DCIS
progression and if such features could be obtained from chromatin images alone without the use of
highly multiplexed staining or high-throughput sequencing. Using unsupervised representation learning
methods, we identified eight distinct morphological cell states just based on the chromatin images and
showed that these distinct cell states were associated with interpretable nuclear and chromatin features.
All cell states were observed in all 3 disease stages and 11 phenotypic categories with different
proportions, indicating that cell states that are enriched in invasive cancer already exist in small fractions
in normal breast tissue. Tissue-level analysis revealed that the spatial organization of the cell states, in
terms of a cell state’s position relative to the ducts and relative to each other, were significantly altered
during DCIS progression. Importantly, we showed that disease stage and phenotypic category could be
accurately predicted just based on statistics of cell state neighborhoods. Collectively, our analysis
demonstrates that chromatin imaging represents a powerful measure of cell state and disease stage of
DCIS, thereby providing a simple and effective imaging-based biomarker for tumor progression.

en: We report the observation of fully magnetically polarized ultrathin La0.8Sr0.2MnO3 films by using LaMnO3 and La0.45Sr0.55MnO3 buffer layers grown epitaxially on SrTiO3(001) substrates by molecular beam epitaxy. Specifically, we show that La0.8Sr0.2MnO3 films grown on 12-unit-cell LaMnO3 have bulk-like magnetic moments starting from a single unit cell thickness, while for the 15-unit-cell La0.45Sr0.55MnO3 buffer layer, the La0.8Sr0.2MnO3 transitions from an antiferromagnetic state to a fully spin-polarized ferromagnetic state at 4 unit cells. The magnetic results are confirmed by X-ray magnetic circular dichroism, while linear dichroic measurements carried out for the La0.8Sr0.2MnO3/La0.45Sr0.55MnO3 series show the presence of an orbital reorganization at the transition from the antiferromagnetic to ferromagnetic state corresponding to a change from a preferred in-plane orbital hole occupancy, characteristic of the A-type antiferromagnetic state of La0.45Sr0.55MnO3, to preferentially out of plane. We interpret our findings in terms of the different electronic charge transfers between the adjacent layers, confined to the unit cell in the case of insulating LaMnO3 and extended to a few unit cells in the case of conducting La0.45Sr0.55MnO3. Our work demonstrates an approach to growing ultrathin mixed-valence manganite films that are fully magnetically polarized from the single unit cell, paving the way to fully exploring the unique electronic properties of this class of strongly correlated oxide materials.

en: The evolution of the magnetic ground state of ultrathin 0–10 unit cells (uc) thick La0.8Sr0.2MnO3 films interfaced to an antiferromagnetic La0.45Sr0.55MnO3/SrTiO3(001) buffer layer was investigated with x-ray photoemission electron microscopy. For 0–3 uc La0.8Sr0.2MnO3, we observe antiferromagnetic domains but no ferromagnetic contrast, showing that nominally ferromagnetic La0.8Sr0.2MnO3 adopts the antiferromagnetic ground state of the buffer layer. For larger thicknesses, ferromagnetic domains emerge, confirming that the additional layers revert to the ferromagnetic ground state. We also observe a drastic increase in the complexity of the domain configuration between 3 and 5 uc, which we attribute to competing magnetic and electronic ground states in the system. We attribute the interfacial modified magnetic ground state to charge sharing at the interface due to the chemical potential mismatch, which leads to hole doping at the La0.8Sr0.2MnO3 interface. The present work sheds light on the impact of charge sharing at the interface of complex oxide materials, in particular on the magnetic and electronic states, and presents a strategy for modulating the electronic ground state properties at metallic interfaces.

en: The resonant excitation of electronic transitions with coherent laser sources creates quantum coherent superpositions of the involved electronic states. Most time-resolved studies have focused on gases or isolated subsystems embedded in insulating solids, aiming for applications in quantum information1–6. Here, we focus on the coherent control of orbital wavefunctions in the correlated quantum material Tb2Ti2O7, which forms an interacting spin liquid ground state. We show that resonant excitation with a strong THz pulse creates a coherent superposition of the lowest energy Tb 4f states. The coherence manifests itself as a macroscopic oscillating magnetic dipole, which is detected by ultrafast resonant x-ray diffraction. We envision the coherent control of orbital wavefunctions demonstrated here to become a new tool for the ultrafast manipulation and investigation of quantum materials.

en: The interaction of magnetic order and spontaneous polarization is a fundamental coupling with the prospect for the control of electronic properties and magnetism. The connection among magnetic order, charge localization and associated metal-insulator transition (MIT) are cornerstones for materials control. Materials that combine both effects are therefore of great interest for testing models that claim the occurrence of spontaneous polarization from and magnetic charge order. One class of materials proposed to combine these functionalities is the family of RNiO3 (R: lanthanide or Y), whose members show a clear MIT and an antiferromagnetic ground state and for which an electric polarization has been predicted. Using resonant magnetic x-ray scattering with circular polarization and an applied electric field we show that YNiO3 possess a magnetic structure containing domains of spin-rotations that are consistent with an electric polarization. We show a reversal of the magnetic structure with the applied electric field confirming that charge ordered RNiO3 are magnetoelectric type II multiferroics with a MIT.

en: In this paper we present a model system built out of artificially layered materials, allowing us to understand the interrelation of magnetic phases with the metallic-insulating phase at long length scales, and enabling new strategies for the design and control of materials in devices. The artificial model system consists of superlattices made of SmNiO3 and NdNiO3 layers, – two members of the fascinating rare earth nickelate family, having different metal-to-insulator and magnetic transition temperatures. By combining two complementary techniques—resonant elastic x-ray scattering and muon spin relaxation—we show how the magnetic order evolves, in this complex multicomponent system, as a function of temperature and superlattice periodicity. We demonstrate that the length scale of the coupling between the antiferromagnetic and paramagnetic phases is longer than that of the electronic metal-insulator phase transition—despite being subsidiary to it. This can be explained via a Landau theory—where the bulk magnetic energy plus a gradient cost between magnetic and nonmagnetic phases is considered. These results provide a clear understanding of the coupling of magnetic transitions in systems sharing identical order parameters.

en: Acoustic tweezers comprising a surface acoustic wave chip and a disposable silicon microfluidic chip are potentially advantageous to stable and cost-effective acoustofluidic experiments while avoiding the cross-contamination by reusing the surface acoustic wave chip and disposing of the microfluidic chip. For such a device, it is important to optimize the chip-to-chip bonding and the size and shape of the microfluidic chip to enhance the available acoustic pressure. In this work, aiming at studying samples with the size of a few tens of microns, we explore the device structure and assembly method of acoustic tweezers. By using a polymer bonding layer and shaping the silicon microfluidic chip via deep reactive ion etching, we were able to attain the acoustic pressure up to 2 MPa with a corresponding acoustic radiation pressure of 0.2 kPa for 50 MHz ultrasound, comparable to reported values at lower ultrasound frequencies. We utilized the fabricated acoustic tweezers for non-contact viscoelastic deformation experiments of soft matter and  trapping of highly motile cells. These results suggests that the feasibility of the hybrid chip approach to attaining the high acoustic force required to conduct acoustomechanical testing of small soft matters and cells.

en: Resonant X-ray diffraction (RXD) provides a unique capability to investigate electronic ordered states in matter. The circular dichroism in RXD can determine the absolute chirality formed by anisotropic multipole arrangement. Here, we demonstrate that the scattering interference between distinct atomic electric multipoles can create circular contrast in resonant RXD even in a non-chiral crystal. These general considerations are applied to 1T-TiSe2, where recently reported circular dichroism in RXD was used to claim chiral charge density wave order. We show that the experimental observations are well reproduced by our ab initio calculations on the basis of the centrosymmetric crystal structure. Our results not only illuminate a way for a better understanding of possible chiral electronic order but also propose a general approach to extract buried high-order atomic multipoles via circular contrast in RXD. Besides, we discuss the difference in the circular dichroism of RXD originated by crystal chirality in chiral crystals and the interference effect in non-chiral crystals.

en: Resonant inelastic x-ray scattering (RIXS) has become a prominent technique to study quasiparticle excitations. With advances in polarization analysis capabilities at different facilities, RIXS offers exceptional potential for investigating symmetry-broken quasiparticles like chiral phonons and magnons. At optical wavelengths birefringence can severely affect polarization states in low-symmetry systems. Here we show its importance for soft x-ray resonances. Given the growing interest in Circular Dichroism (CD) in RIXS, it is important to evaluate how birefringence may affect the RIXS spectra of anisotropic systems. We investigate CuO, a well-known anisotropic material, using Cu L3-edge RIXS and detect significant CD in both magnetic and orbital excitations in the collinear antiferromagnetic phase. We demonstrate that the CD can be modeled by a proper treatment of RIXS scattering amplitudes derived from single-ion calculations with birefringence. Recognizing these effects is crucial for unambiguous identification of subtle dichroic effects induced by symmetry-broken quasiparticles. Furthermore, the combined sensitivity of RIXS and birefringence to local symmetry presents an opportunity to study microscopic changes driven by external perturbations.

en: Chirality is a fundamental symmetry element existing at disparate scales and in many categories of scientific fields. Even though symmetry breaking is an indispensable concept for describing qualitatively distinct phenomena, symmetry cannot quantitatively predict measurable quantities. Since chirality is ternary, i.e., left-handed, right-handed, or achiral, the role of its “amplitude” in material properties is habitually not addressed. Considering the role of “amplitude” for time-reversal symmetry breaking, which can be described by magnetization, chirality amplitude is intuitively a key quantity for controlling emergent phenomena. Here, we propose two types of chiral order parameters and demonstrate the tunability of their amplitude at ultrafast timescales. Resonant X-ray diffraction with circular polarization is an established technique to measure crystal chirality directly. Extending this technique to the time domain, we quantify the ultrafast change in chirality amplitude in real time after an optical excitation. Besides, using a THz excitation, we observe oscillations in the resonant diffraction intensities with specific phonon frequencies. This indicates the creation of additional asymmetry, which could also be described as an enhancement in chirality amplitude. Our proposed concept of chirality amplitude and its ultrafast control may lead to a unique approach to control chirality-induced emergent phenomena at ultrafast timescales.

en: Van der Waals (vdW) materials exhibit a variety of states that can be switched with low power at low temperatures, offering a viable cryogenic "flash memory" required for the classical control electronics for solid-state quantum information processing. In 1T-TaS2, a non-volatile metallic 'hidden' state can be induced from an insulating equilibrium charge-density wave ground state using either optical or electrical pulses. Given that conventional memristors form localized, filamentary channels which support the current, a key question for design concerns the geometry of the conduction region in highly energy-efficient 1T-TaS2 devices. Here, we report in operando micro-beam X-ray diffraction, fluorescence, and concurrent transport measurements, allowing us to spatially image the non-thermal hidden state induced by electrical switching of 1T-TaS2. Our results reveal a long-range ordered, non-filamentary switched state that extends well below the electrodes, implying that the self-organized, collective growth of the hidden phase is driven by a combination of charge flow and lattice strain. Our unique combination of techniques showcases the potential of non-destructive, three-dimensional X-ray imaging to study bulk switching properties in microscopic detail, namely electrical control of the vdW layer stacking.

en: The binding and release of ligands from their protein targets is central to fundamental biological processes as well as to drug discovery. Photopharmacology introduces chemical triggers that allow the changing of ligand affinities and thus biological activity by light. Insight into the molecular mechanisms of photopharmacology is largely missing because the relevant transitions during the light-triggered reaction cannot be resolved by conventional structural biology. Using time-resolved serial crystallography at a synchrotron and X-ray free-electron laser, we have captured the release of azo-combretastatin A4 and the resulting conformational changes in tubulin. Nine structural snapshots from 1 ns to 100 ms complemented by simulations show how cis-to-trans isomerization of the azobenzene bond leads to a switch in ligand affinity, opening of an exit channel, and collapse of the binding pocket upon ligand release. The resulting global backbone rearrangements are related to the action mechanism of tubulin-binding drugs against gout, cancer, and COVID-19.

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.

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.
