UNIVERSITY PARK, Pa. — 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 ...
(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 ...
(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 ...
