This diagram shows (left) a nitrogen vacancy in a diamond lattice, and (right) a divacancy defect complex in silicon carbide. Spins from carbon-13 and silicon-29 are marked. Note the greater distance between atoms in the lattice in the silicon carbide--part of the reason the silicon carbide allows for longer-lived qubits. Courtesy of Hosung Seo.
Fabriion and Surface Interactions of Super-Hydrophobic
Hydrophilic silicon carbide was modified by surface deposition of a super-hydrophobic coating that is based on perfluorosilanes. The modifiion was proven to yield merane surfaces with contact angles that were higher than 145° and to be stable under hydrothermal conditions.

Fluorescent SiC as a new material for white LEDs - IOPscience
Mar 15, 2012· Silicon carbide is a semiconductor with an indirect bandgap. The indirect bandgap materials are often believed to have low efficiency in the optical recoination. It was, however, demonstrated that silicon carbide, which is doped to provide donor-to-acceptor pair luminescence, can have an extremely high quantum efficiency [ 10 ].
The Mysteries of the AFIP Report
Interestingly, however, the shape of the "silicon carbide" pieces in picture P-27-D look very much like what''s in the cluster of "silicon carbide" pieces in picture P-27-C. And the scale is the same! The sample nuers (SPS02-88-01) on the images say it they are again from the New York Post powder.

Mohs scale of mineral hardness - Wikipedia
The Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.
