Every engineer's nightmare

The scientists took advantage of the fact that chirality affects an electron property called "spin", which is characterized by two states - "spin up" and "spin down" - similar to the spinning of a spinning top clockwise or counterclockwise. Illustration: Prof. Ron Naaman, Weizmann Institute

Silver nanoparticles used in an innovative spectroscopic method

The photonic big bang: weak disorder creates a weak nanometric separation between photons with opposite spin (red and blue) - "photonic spin-Hall effect". Only in complete disorder does the "photonic explosion" occur - photons with opposite spins split and fill the entire momentum space - the "photonic Rashba effect". The phenomenon describes a topological phase transition that manifests itself in symmetry breaking. The research was inspired by models in cosmology that describe the Big Bang. Silicon nanoantennas are depicted in the picture, and the transition from antennas ordered in their direction to complete disorder is expressed by measuring a sharp increase in entropy (as a measure of disorder).

The clothing that cools the wearer

Computer simulation of the atomistic model of the particle. It can be seen that the material moved by the diamond needle accumulates at the edge of the particle and creates unique steps, which are later used as "guide rails" that return to the footprint, by diffusion, the material moved to the side. After a time the particle returns to its original shape. Source: Courtesy of the Technion.

Has a cheap and efficient method been found to produce graphene?

Even light clothes made of cotton fabric absorb the infrared radiation emitted by our bodies and in this way trap heat. New research suggests developing a unique fabric with nanometer holes, which allow radiation to escape through it. Illustration: pixabay.
