Materials having excess electrons are typically conductors.
A team at the University of Colorado Boulder has designed new kinds of liquid crystals that mirror the complex structures of some solid crystals--a major step forward in building flowing materials that can match the colorful diversity of forms seen in minerals and gems, from lazulite to topaz.
As COVID-19 spreads via respiratory droplets, researchers have become increasingly interested in the drying of droplets on impermeable and porous surfaces. Surfaces that accelerate evaporation can decelerate the spread of the COVID-19 virus.
Science always strives to replace complex natural objects and phenomena with simpler models. Scientists of Samara Center for Theoretical Materials Science (SCTMS) of Samara Polytech have developed methods to simplify the crystal structure of a substance to obtain chemically important knowledge. The main approaches are described in the article published in the Structural Chemistry journal IF 2.081 (doi:10.1007/s11224-020-01724-4).
Cryopreservation involves preserving biological materials, such as cells, tissues, and organs, at ultra-low temperatures so that they can be revived and used at a later date.
Scientists at Osaka University have created lithium-ion battery (LIB) electrodes with silicon (Si) swarf or graphite sheet composites. This helped achieve a reduction in cost, environmental friendliness, and high performance.
In certain materials, electrical and mechanical effects are closely linked: for example, the material may change its shape when an electrical field is applied or, conversely, an electrical field may be created when the material is deformed. Such electromechanically active materials are very important for many technical applications.
A scientific collaboration including the companies Nanox, AplFilm, Braskem and the UFSCar (Brazil) and Jaume I of Castellón (Spain) universities has launched a plastic film with the potential to deactivate 99.99% of the novel coronavirus in just 15 minutes.
Between chemistry classes, gemstones, and electronics, the idea of crystals, substances with an ordered and periodic arrangement of atoms is quite common. But about 40 years ago, a strange particle was discovered by scientists that hasn't become commonplace in our world yet: quasicrystals.
Catalysts are key materials in modern society, enabling selective conversion of raw materials into valuable products while reducing waste and saving energy. In case of industrially relevant oxidative dehydrogenation reactions, most known catalyst systems are based on transition metals such as Iron, Vanadium, Molybdenum or Silver.
