First, the researchers used a short laser pulse about 200 nanometers in wavelength to excite ammonia molecules. This pump ...

During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...

Scientists at the Paul Scherrer Institute PSI have refined an X-ray diffraction technique for detecting biological structures ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

Abstract: The concept of metagratings has been proposed as an efficient method of controlling the diffraction field of electromagnetic waves. In this paper, a reflective metagrating with ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...

The original version of this story appeared in Quanta Magazine. Since their discovery in 1982, exotic materials known as quasicrystals have bedeviled physicists and chemists. Their atoms arrange ...
