(PhysOrg.com) -- Peering through a transmission electron microscope (TEM), researchers from Germany, Spain, and the UK have observed graphene sheets transforming into spherical fullerenes, better known as buckyballs, for ...
(PhysOrg.com) -- One of the drawbacks associated with using semiconductor lasers is that many of them can only produce a beam of a single wavelength, and can only send that beam in one direction at a time. There have been ...
(PhysOrg.com) -- “Most current hard x-ray interferometers are based on crystals, which require their high quality and high mechanical stability,” Anatoly Snigirev tells PhysOrg.com. “This can make x-ray interferometry ...
Particle accelerators hold great potential for semiconductor applications, medical imaging and therapy, and research in materials, energy and medicine. But conventional accelerators require plenty of elbow room—kilometers—making ...
