source:Tech XploreElectronics engineers and materials scientists have been trying to identify materials that could help to boost the performance of electronics further, overcoming the inherent limitations of silicon-based transistors. Two-dimensional (2D) semiconductors have advantageous properties that make them promising candidates for the development of better performing transistors.Most notably, 2D semiconductors are atomically thick and exhibit high carrier mobilities, two qualities that could improve the electrostatic control and ON-state performances of short-channel field-effect transi...

source:Innovation news networkAn old cryolite mine and an untapped rare earth endowment hold unique importance for greater powers than its junior Australian owner.A chasm of an open pit resting on the banks of the fjords of the Labrador Sea looked more the part of a biblical disaster than a mine.However, the Greenlanders of the twin settlements of ‘Green Valley’ Kangilínguit and Grønnedal didn’t build their townships around a cataclysm, but Ivigtût, a massive and singular known naturally occurring source of cryolite.Greenland’s historical mining importanceIvigtût was mined ...

source:KeAi Communications Co.The hot-end components of high-performance high-speed aircraft need to meet performance requirements such as long service life, wide temperature range oxidation resistance and ablation resistance. This puts forward higher requirements for high-temperature service performance of thermal protection system (TPS).With low density, low expansion and excellent high temperature mechanical properties, carbon-carbon (C/C) composites are expected to be the best choice for the new generation of TPS. However, the oxidation sensitivity of C/C composites severely limits their s...
