In the early 2000s, scientists observed lightning discharge producing X-rays comprising high energy photons -- the same type used for medical imaging. Researchers could recreate this phenomenon in the ...
(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 ...
Scientists using NASA’s Swift satellite have detected X-rays from a comet that is now passing the Earth and rapidly disintegrating on what could be its final orbit around the sun. Swift’s observations ...

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, ...
(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 ...

Since the X-rays produced could be controlled to be either diffused or focused, the new method could offer more flexibility in performing X-ray imaging for health screening, such as imaging an entire ...
