Ultrafast and coupled – atomic vibrations in the quantum material boron nitride
Oct 12, 2021 (Nanowerk News) Materials consisting of a few atomic layers display properties determined by quantum physics. In a stack of such layers, vibrations of the atoms can be triggered by infrared light. New experimental and theoretical work shows that atomic vibrations within the layers of hexagonal boron nitride,...
Nanotechnology Now – Press Release: How flawed diamonds ‘lead’ to flawless quantum networks
Home > Press > How flawed diamonds 'lead' to flawless quantum networksCREDIT Tokyo TechAbstract:The color in a diamond comes from a defect, or vacancy, where there is a missing carbon atom in the crystal lattice. Vacancies have long been of interest to electronics researchers because they can be used as...
Living optical fibers expand the use of photonics for bioengineering
Oct 11, 2021 (Nanowerk Spotlight) Glass is one of the oldest manufactured materials used by humans and glass making dates back at least 6000 years, long before humans had discovered how to smelt iron. Glasses have been based on the chemical compound silica – silicon dioxide, or quartz – the...

New measurement method promises spectacular insights into the interior of planets
Oct 05, 2021 (Nanowerk News) At the heart of planets, extreme states are to be found: temperatures of thousands of degrees, pressures a million times greater than atmospheric pressure. They can therefore only be explored directly to a limited extent – which is why the expert community is trying to...
