A novel bifunctional in situ FTIR cell has been elaborately designed and prepared. By coupling with a single-reflection IR mode, a facile and general in situ synchrotron FTIR spectroscopic method has been developed based on the well designed in situ FTIR cell for the surface dynamic studies of electrodes during electrolysis.

The work shows by combining with helical acquisition mode, synchrotron radiation propagation-based imaging computed tomography (SR-PBI-CT) is a powerful tool for tissue engineering applications with the image qualities of high contrast, low noise level, and most importantly fewer ring artifacts.

We show which elements are best able to be quantifiable by synchrotron radiation for microprobe X-ray fluorescence (SR-µXRF) imaging for understanding elemental distributions in plant tissues, with a focus on metals and metalloids in rice grain. This work provides SR-µXRF users with data to understand which elements can be reliably quantified and guidance on how to consider the limitations of the technique to best interpret such data.

A beam-splitting off-axis zone plate setup to measure transient X-ray absorption spectroscopy is presented, as implemented at the Spectroscopy & Coherent Scattering instrument at the European X-Ray Free-Electron Laser.

As the performance of synchrotron radiation sources has increased significantly, higher requirements have been placed on the stability of DCM. Traditional passive vibration control techniques, such as optimized structures, elastic damping, and vibration-absorbing materials, are difficult to meet the future requirements of DCM.Proposed method is of great significance to the research of ultra-high stability DCM in synchrotron radiation facilities.

A novel microfluidic rotating-target device capable of three-degrees-of-freedom motion has been proposed, and its feasibility for sample delivery was successfully verified at a synchrotron radiation facility. This device guarantees the full utilization of crystals and only 0.1 mg of protein is consumed in collecting a complete dataset.

The properties of the recently installed split-and-delay unit at beamlines FL23 and FL24 at FLASH2 are presented. Its operational range, performance parameters and results of a first experiment are described.

The design and performance of a new dedicated spectromicroscopy beamline at the Swedish national synchrotron (MAXIV) is presented.

The development of synchrotron-radiation-based high-energy X-ray micro-lamino­graphy to visualize microstructures in dense planar objects such as planar fossils is described.

The effects of zone materials and zone shapes on the focusing/imaging quality of dielectric kinoform zone plates have been theoretically investigated by a modified thin-grating-approximation method. Greyscale electron beam lithography was applied to generate 3D kinoform zones in HSQ and PMMA for soft X-rays. The dielectric kinoform zone plate lens demonstrates high diffraction efficiency well beyond conventional X-ray optics.

For irreversible or slow reactions studies by time-resolved pump–probe X-ray solution scattering, the standard sample cell and protocol for data collection at the BioCARS 14-ID beamline potentially require up to hundreds of milligrams of sample. A sheath co-flow cell, described here, allows such solution scattering measurements to be conducted with the sample consumption reduced by more than ten times compared with standard protocols at this beamline.

The soft X-ray beam from the SASE3 source at the European XFEL is delivered to the SQS instrument by a beam transport system. The system layout and performances are reported.
