Green, hard, flexible and even edible

Plastic waste accumulates in the heart of the oceans and on the ground and tiny plastic particles enter our bloodstream. As long as suitable substitutes are not found for the common industrial material, this pollution is expected to continue and even increase. Institute scientists

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).

In the study, the scientists examined collisions that occur between the molecules. Collisions of atoms have been studied in the past, but atoms - according to classical physics - are spherical, while molecules have an elongated structure. The structure of a colliding body affects the way it will move after the collision. Will elongated molecules behave differently from spherical atoms? And is knowing their shape enough to predict the outcome of the collision? Illustration: pixabay.com.

Detection of chemical activity on the surface of nanometer-sized platinum particles, which are used as catalysts in the chemical industry, was made possible by focusing infrared light onto a nanometer-sized needle. These measurements showed for the first time how and where chemical activity occurs on the surface of the particles

The image depicts a three-dimensional illustration of the disappearance cloak of a metasurface consisting of an ultra-thin layer of nano-antennas (gold particles) that masks the underlying bone. The light is deflected out of the surface of the cloak (red arrows) as it would be deflected by a flat mirror. [Courtesy: Xiang Zhang group, Berkeley Lab/UC Berkeley]
