Conversion Process of Amorphous Si-Al-C-O Fiber into …
That is to say, it was estimated that the surface layer of the modified Si-Al-C-O fiber existed as some oxide forms of silicon. Accordingly, it was considered that the oxygen-rich surface layer was relatively stable compared with the inside Si-O-C structure, and also this surface layer played an important role as a good supplier of SiO gas during the initial degradation processes.

Flat dentinal surfaces with standardized smear layers were created by grinding buccal surfaces with #600 silicon carbide papers (Norton, Campinas, Brazil). Specimens were randomly divided into six prophylaxis groups, as follows: 1) Cont, no cavity cleaner appliion, 15-second water-spray, and conventional etching (control group).

tend to be difﬁ cult to fabrie with nanoscale ﬁ delity. Here a novel process is described, whereby the surfaces of pre-existing, nanoscale Si tips are exposed to carbon ions and then annealed, to form a strong silicon carbide (SiC) layer. The nanoscale
How to GaN: Intro to Gallium Nitride (GaN) Transistor …
Adapting this phenomenon to gallium nitride grown on silicon carbide, Eudyna was able to produce benchmark power gain in the multi-gigahertz frequency range. In 2005, Nitr Corporation introduced the first depletion mode RF HEMT transistor made with GaN grown on silicon wafers using their SIGANTIC® technology.
