Impressive progress has also been made in silicon carbide, with the first SPE detected in 2014 (); subsequent achievements were reviewed in Reference 33. Other materials in which defect-related single-photon emission has been reported include hexagonal boron nitride, transition metal dichalcogenides (WSe 2 and MoS 2 ), zinc oxide, and gallium nitride ( 25 ).

Thallium - Wikipedia

Thallium is a chemical element with the syol Tl and atomic nuer 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium reseles tin, but discolors when exposed to air. Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid

Simulating Mechanical Behavior of Ceramics Under …

The mechanical behavior of ceramics in extreme environments can be qualitatively different from that observed at aient conditions and at typical loading rates. For instance, during shock loading the fracture of ceramics is not controlled by the largest flaw. Computer simulations play an increasingly important role in understanding and predicting material behavior, in particular under

Scandium - Wikipedia

Scandium is a chemical element with the syol Sc and atomic nuer 21. A silvery-white metallic d-block element, it has historically been classified as a rare-earth element,[6] together with yttrium and the lanthanides. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia. Scandium is present
