A reactor is described, whose modular design enables in situ X-ray scattering and spectroscopy, infrared spectroscopy, gas and liquid injection under autoclave-like conditions and magnetic stirring for solvothermal synthesis up to 200°C and 8 bar.

An analysis of experimental artifacts in time-resolved X-ray solution scattering data acquired at high repetition rate XFEL sources, specifically at the FXE instrument at the European XFEL, is presented.

It has been 50 years since the publication in PNAS of our first results on the utilization and demonstrated benefits of synchrotron radiation for macromolecular crystallography. In this brief article, I offer some personal observations and comments about that early research at Stanford and the Stanford Synchrotron Radiation Project (SSRP, later renamed SSRL), how it evolved, and consider key factors in how and why synchrotron radiation ultimately catalyzed a new and transformational paradigm for study of the structure of biomolecules.

We provide a historical introduction and our thoughts on the current trends including some based on papers in this special issue of Journal of Synchrotron Radiation celebrating the 50th Anniversary of the Stanford SSRL synchrotron radiation and protein crystallography initiative led by Keith Hodgson.

An introduction is provided to the extended (atmospheric pressure) capabilities of the Single-Particle, Clusters and Biomolecules and Serial Femtosecond Crystallography (SPB/SFX) scientific instrument at the European X-ray Free-Electron Laser facility.

This work provides guidelines on how to meaningfully perform a dip-and-pull X-ray photoelectron spectroscopy (XPS) experiment applied to electrochemistry and electrocatalysis to obtain information on both the electrode properties and the electrode/electrolyte interface. The aim is to facilitate access to the dip-and-pull XPS method to newcomers from the field of electrochemistry.

This work investigates the temporal effects of refractive X-ray lenses on ultra-short pulses from X-ray free-electron lasers. Using both a full Fresnel theory model and a simplified ray-tracing approach, the paper analyzes the pulse elongation and spatio-temporal distortions introduced by these focusing optics.

MAPI is a modular web-based framework designed to unite legacy analysis code with heterogeneous backends (edge, on-premises, high-performance computing, cloud), dramatically accelerating data analysis workflows and offering a scalable flexible blueprint for modernizing synchrotron data analysis.

We present a reinforcement learning based approach to X-ray imaging which allows for up to an order of magnitude lower exposure time to reach the same image quality as with a standard raster scan. This is achieved by splitting the imaging task into several steps and letting initial measurements inform the exposure distribution at later stages of the sequence.

This article reports a versatile operando X-ray absorption spectroscopy (XAS) cell and set-up for the photocatalytic reduction of CO2 in the gas phase, which is validated individually for both photocatalysis and XAS measurements. A detailed operando experiment reveals the link between Mo species evolution and deactivation of the photocatalyst.

We present Gaia, a cryogenically cooled monolithic array of 96 high-purity germanium pixel detectors integrated with a custom low-noise application-specific integrated circuit and a field-programmable gate array-based data acquisition system. The system achieves an average energy resolution of 711 eV at 122 keV and 253 eV at 5.89 keV, and serves as the foundation for a forthcoming 384-pixel detector.

Here, we present SELUN, a novel X-ray photon counting hybrid pixel detector developed at DECTRIS Ltd for coherent diffraction imaging techniques at synchrotron facilities.

The newest seven members of the Editorial Board of Journal of Synchrotron Radiation are introduced.

We present HoToPy, a toolbox for X-ray holo-tomography in Python. It offers state-of-the-art phase retrieval methods for synchrotron and laboratory sources as well as tomographic reconstruction and alignment methods.

The BL46XU beamline at SPring-8 has been restructured for hard X-ray photoelectron spectroscopy (HAXPES), featuring two specialized HAXPES instruments and advanced X-ray optics for high-throughput and ambient-pressure measurements. This article outlines the beamline design, performance and recent scientific achievements enabled by these upgrades.

We investigate the effect of anisotropic absorption of scattered X-rays in X-ray diffraction tomography and show that the detrimental effect on reconstruction is small in the range of absorption coefficients and scattering angles commonly used.

The use of ultra-thin (<2 µm) silicon carbide membranes as in-line beam intensity and position monitors for soft and tender X-ray beamlines is investigated. Experimental results and theoretical simulations highlight the limitations of four-quadrant sensor designs, and alternative solutions for high-resolution and minimally interfering beam monitoring are proposed.

An automated alignment system for nanofocusing Kirkpatrick–Baez mirrors has been developed at SACLA. A wavefront optimization technique routinely provides nanofocused XFEL beams.

The High Energy Photon Source (HEPS) is the first fourth-generation synchrotron radiation source in China. In this paper, the diagnostic process of the Tender X-ray Beamline (TEX), the first bending magnet beamline of HEPS, and its performance are introduced in detail.

A laser reaction chamber has been developed for in situ/operando X-ray diffraction measurements on the NSLS-II 28-ID-2 beamline, allowing for rapid sample heating under various gas and vacuum conditions. This capability has enabled the tracking of chemical reaction kinetics in polycrystalline iron oxide and a reversible phase transformation in WTe2 with 1 s time resolution, expanding the opportunities for dynamic studies in both bulk and single-crystal materials.

The nonuniform internal structure of a printer-toner particle with an approximate size of 5 µm was visualized at a resolution of 141 nm using cryogenic X-ray diffraction imaging tomography.
