Carbon fibers are also composited with other materials, such as graphite, to form reinforced carbon-carbon composites, which have a very high heat tolerance. The disc is usually made of cast iron, but may in some cases be made of composites such as reinforced carbon–carbon or ceramic matrix composites. Furthermore, disk brake systems of airplanes and racing cars are using carbon/carbon
Silicon & Silicon nanostructures: from recent …
For nanocrystalline silicon oxide (nc-SiOx:H) and silicon carbide (nc-SiC:H), they can be used as a superior window layer or back reflector due to their wide bandgap and low refractive index. In this contribution, we use alytic-doping (-doping), a novel post-deposition doping method based on hot wire chemical vapor deposition, to get higher conductivity than those achievable from as
