Quantitative visualization of a gas diffusion layer in a polymer electrolyte fuel cell using synchrotron X-ray imaging techniques

The porosity distribution of a gas diffusion layer shows cyclic variation under freeze-and-thaw cycles. A small porosity variation induces a large change of permeability in the gas diffusion layer.

Detection of circulating tumor cells via an X-ray imaging technique

With selective incorporation of gold nanoparticles into tumor cells, individual cancer cells are detected by an X-ray imaging technique.

Time-resolved X-ray PIV technique for diagnosing opaque biofluid flow with insufficient X-ray fluxes

The temporal resolution of the X-ray particle image velocimetry technique is greatly improved by adopting an image intensifier at beamlines with insufficient X-ray fluxes. Proper digital image processing methods are found to be inevitably useful for improving the image quality and enhancing measurement accuracy.

High-resolution crystal structure of Streptococcus pyogenes β-NAD⁺ glycohydrolase in complex with its endogenous inhibitor IFS reveals a highly water-rich interface

The crystal structure of the complex between the C-terminal domain of Streptococcus pyogenes β-NAD⁺ glycohydrolase and an endogenous inhibitor for SPN was determined at 1.70 Å. It reveals that the interface between the two proteins is highly rich in water molecules.
