(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 ...

It’s amazing how quickly medical science made radiography one of its main diagnostic tools. Medicine had barely emerged from its Dark Age of bloodletting and the four humours when X-rays were ...

The diverging X-rays produced can be used for X-ray imaging, such as for a hand, but the image is dim and its quality is not very high. (b) The electrons are waveshaped using a waveshaping instrument, ...

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 ...

(Nanowerk News) 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 ...

The basic mechanism is similar to how X-rays are conventionally produced using X-ray tubes. But there is a twist: in the simulations, the wave-like patterns of how the electrons travel are “shaped” in ...
