Sabyasachi Kar from the Harbin Institute of Technology, China, and Yew Kam Ho from the Academia Sinica, Taipei, Taiwan, have now characterised the higher energy levels reached by electrons in resonance in three-particle systems, which are too complex to be described using simple equations. This theoretical model, published in a recent study in EPJ D, is intended to offer guidance for experimentalists interested in observing these resonant structures in positronium ions.
SiC-based electrical devices degrading will be improved by controlling the semiconductor material deformation with atomic level.
For the first time, physicists present a unified theory explaining two characteristic features of frustrated magnets and why they're often seen together.
Exploring the mystery of the molecular handedness in nature, scientists have proposed a new experimental scheme to create custom-made mirror molecules for analysis. The technique can make ordinary molecules spin so fast that they lose their normal symmetry and shape and instead form mirrored versions of each other. The research team from DESY, Universität Hamburg and University College London around group leader Jochen Küpper describes the innovative method in the journal Physical Review Letters.
Scientists from IOCB Prague and IMC have developed a revolutionary method for the easy and inexpensive production of irradiated nanodiamonds and other nanomaterials suitable for use in highly sensitive diagnostics of diseases, including various types of cancer. Their article was recently published in Nature Communications.
Scientists from Russia found a way of improving the crystal structure prediction algorithms, making the discovery of new compounds multiple times faster.
Scientists have used high pressure and high temperature experiments to recreate an unusually complex form of nitrogen in the lab for the first time.
Small molecules -- from naturally occurring metabolites and hormones to synthetic medicines and pesticides -- can have big effects on living things. But for scientists to understand how the molecules work and how to design beneficial ones, they need to know the precise arrangement of atoms and chemical bonds. Now researchers have found a faster, simpler and potentially more reliable way to solve the structures of small molecules. They report their results in ACS Central Science.
Fluids exhibiting scaling behavior can be found in diverse physical phenomena, observed when these fluids reach a critical point. In a recent study published in EPJ B, Michal Hnatič from Šafárik University in Košice, Slovakia, and colleagues investigate the influence of ambient turbulent speed fluctuations in physical systems when they reach a critical point.
Excited photo-emitters can cooperate and radiate simultaneously, a phenomenon called superfluorescence. Researchers from Empa and ETH Zurich, together with colleagues from IBM Research Zurich, have recently been able to create this effect with long-range ordered nanocrystal superlattices. This discovery could enable future developments in LED lighting, quantum sensing, quantum communication and future quantum computing. The study has just been published in the renowned journal Nature.
