Two dimensional transition metal chalcogenides have multi valley structures in their energy bands, giving them electron valley degrees of freedom, making them an ideal platform for studying multi body interactions. As the main mechanism of valley depolarization, the valley scattering process of free electrons or bound excitons is crucial for exploring excited state electron phonon interactions and...
Refractory material can withstand high temperature above 1500℃. They are essential materials for industrial furnaces that produce glass or ceramics, non-ferrous metals and steel. The service life of manufactured refractory products can range from a few days to many years, depending on the material, the temperature in the melting vessel and other operating parameters. As a result, although ...
An international team of scientists is rethinking the fundamental principles of radiation physics, aiming to create ultra bright light sources. In a new study published in Nature Photonics, researchers from the Higher Institute of Technology in Lisbon, Portugal, the University of Rochester, the University of California, Los Angeles, and the Optical Applications Laboratory in France proposed the us...
Casir is about to launch the H6 4K UST tricolor laser projector through Indiegogo. The new laser projector has a brightness of up to 3000 ANSI lumens and a BT.2020 color gamut coverage of 110%. It is an ultra short focus projector that runs on Android TV.The Casiris H6 4K UST tricolor laser projector is a brighter and more accurate version of the Casiris A6. It also has greater image projection ca...
In the last century, the improvement of mechanical properties of structural metals was mainly achieved through the creation of increasingly complex chemical compositions. The complexity of this ingredient increases costs, creates supply fragility, and makes recycling more complex.As a relatively new metal processing technology, metal 3D printing provides the possibility to re-examine and simplify ...
