X-ray optics on a chip
Waveguides are widely used for filtering, confining, guiding, coupling or splitting beams of visible light. However, creating waveguides that could do the same for X-rays has posed tremendous challenges in fabrication, so ...

(Phys.org)—A team of researchers working at Philipps-Universität Marburg, in Germany has created a new kind of material that is able to convert a near-infrared laser beam into a visible beam of light. In their paper published ...
Diamonds are one of the most coveted gemstones. But while some may want the perfect diamond for its sparkle, physicists covet the right diamonds to perfect their experiments. The gem is a key component in a novel system that ...
