Silicon nanoparticle generation and deposition on glass …

2020/6/1· Carbon reacts with oxygen more easily than with silicon since the enthalpy of carbon-dioxide formation is much lower than that of silicon-carbide formation [33,34]. This situation is different from the reaction sintering process where SiC formation occurs by nanosecond pulsed laser irradiation on pellets of a stoichiometric powder mixture of Si and C under Ar gas flow [ 35 ].

2014/11/20· Silicon carbide appears to be completely inert with respect to biological systems; however, like other materials, it can interact with living cells when nanostructured. The literature describes two basic effects of these interactions: mechanical damage and oxidative stress caused by the presence of highly reactive chemical species on the surface of the nanostructures [ 15 – 17 ].

Tungsten carbide - Wikipedia

Tungsten carbide is approximately twice as stiff as steel, with a Young''s modulus of approximately 530–700 GPa (77,000 to 102,000 ksi), and is double the density of steel—nearly midway between that of lead and gold.It is comparable with corundum (α-Al2 O 3) in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitride and diamond powder
