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.
