A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with X-ray pulses being circulated between crystal mirrors and amplified in the ...
European XFEL, the biggest X-ray laser in the world, has generated its first X-ray laser light. The X-ray light has a wavelength of 0.8 nm -- about 500 times shorter than that of visible light. At ...
Like a tiny needle in a sprawling hayfield, a single crystal grain measuring just tens of millionths of a meter - found in a borehole sample drilled in Central Siberia - had an unexpected chemical ...
