X-ray phase-contrast imaging has recently led to a revolution in resolving power and tissue contrast in biomedical imaging, microscopy and materials science. The necessary high spatial coherence is ...

(a) Ordinary electrons without wave shaping have a uniform wave pattern when they travel. In simulations, the electrons collide with the atoms in graphene (red spheres represent graphene atoms and ...

Using the industry's biggest inspection machines to examine its smallest objects sounds like a perfect paradox, but for x-ray inspection done during development, quality assurance, or off-line defect ...

Dim lights in order to make the electron beam more visible. Wire up the heater and accelerator contacts (and also deflector contacts, if desired) on the tube to the power supply (or supplies). If ...

Scientists led by Nanyang Technological University, Singapore (NTU Singapore) have developed and simulated a new energy-efficient way to generate highly focused and finely controlled X-rays that are ...
