A new in situ facility (Flow-Xl) for the characterization of crystallization systems in flow using combined in situ X-ray diffraction and Raman spectroscopy is presented. This article highlights commissioning and calibration experiments on case-study systems that stress the utility of the instrument for extracting reproducible qualitative and quantitative phase information during crystallization processes.

Synchrotron X-ray irradiation on continuous-flow aqueous precursors produced conducting Au nano-meshes suitable for transparent and flexible electrodes for optoelectronics.

Serial crystallography, in which X-ray diffraction data are recorded from a sequence of microcrystals in serial fashion, requires a platform for sample delivery. This work describes a simple flow cell device designed to deliver protein microcrystals to an X-ray beam during serial X-ray crystallography studies using synchrotron radiation.

Full pattern analyses of small-angle X-ray and neutron scattering data with both discrete reflections and central diffuse scattering are presented. Data with both equatorial streaks and two- and four-point reflections can be fitted in elliptical coordinates with relatively few parameters.

The development and characterization are described of a co-flow injector for liquid-jet crystal delivery applied for serial crystallography with X-ray free-electron lasers.

A novel method is introduced for in situ X-ray total scattering experiments. Two examples of the method as applied to non-classical nucleation and crystal growth studies are discussed.

Ab initio molecular dynamics has been used to study the structure of a WSe₂ multilayer deposited on silicon.

A new electrochemical cell design enables air-free in situ synchrotron grazing-incidence X-ray diffraction measurements of Li-containing species during non-aqueous Li-mediated electrochemical nitro­gen reduction. Such measurements will facilitate the development of a mechanistic understanding of the electrode–electrolyte interface under Li-N₂R conditions, allowing for the rational design of Li-N₂R toward improved Faradaic efficiency toward NH₃.

An apparatus for the optimization of crystal growth using precise temperature control and dialysis combined with real-time visualization has been developed.

The design and performance of a novel micro-reactor in situ flow cell permitting investigation of model catalysts with grazing-incidence small- and wide-angle X-ray scattering is presented.
