A phase change in post-perovskite materials at the so-called D” discontinuity is also evidence for long-predicted slow, convective flows in the mantle itself ...

A new material developed at Penn State defies a fundamental law of physics, opening doors to highly efficient solar cells.

Using nuclear magnetic resonance, researchers at ETH Zurich have studied the atomic environments of single platinum atoms in ...

We report measurements and traceability of terahertz wavelength and frequency. Terahertz frequency comb is used for traceability of terahertz frequency. Frequency of a stable source is precisely ...

Abstract An integral semi-analytical solution of the atmospheric diffusion equation considering wind speed as a function of both downwind distance from a pollution source and vertical height is ...

We propose a novel and simple scheme for high-frequency photonic vector millimeter-wave (mm-wave) signal generation based on photonic frequency doubling enabled by a single directly modulated laser ...

The principle of wave-particle duality is crucial in quantum physics, highlighting the dual nature of light and matter and ...

At the air-water interface, a negatively charged amino acid carries out a nucleophile attack on a gas molecule to convert it into a product. The reaction rate is enhanced due to significant ...
