In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy, unstable atomic nuclei. Mapping the gamma-ray emissions of so many ...

Semiconductor surfaces can generally be studied only with considerable experimental effort, for example, in an ultrahigh ...

Scientists at Nanyang Technological University in Singapore have discovered a surprisingly simple way to create exotic light ...

The metasurface is the six-millimetre-sized circle at the centre of the disk. (Courtesy: Noah Rubin) A compact optical ...

Benzene, toluene, and xylene (BTX) are serious air pollutants emitted by the chemical industry. Real-time monitoring of these air pollutants would be a valuable tool to regulate emissions of these ...

Solutions of hydrogen peroxide (∼1 mol·L –1) were analyzed by Raman spectroscopy outside the hot cell using a 1800 gr/mm grating. Spectra were recorded for 5 × 30 s by focusing the laser inside a drop ...
