WebSiC dust could be a significant constituent of interstellar dust since it is generally believed that carbon stars inject a considerable amount of dust into the interstellar medium (ISM). The presence of SiC dust in the ISM is also supported by the identification of pre-solar SiC grains of stellar origin in primitive meteorites. WebA low C/SiO2 ratio resulted in -SiC powder with spherical morphology, while agglomerates consisting of fine SiC particles were obtained at the C/SiO2 ratio of 3. High-purity SiC powder (99.95%) could be obtained with C/SiO2 = 0.5 and 3 at 1525 C for 5 h. Keywords:siliconcarbide(SiC);silica(SiO2);aerogel;surfacemethyl(-CH3)group ...

WebIn 1988, Ledoux et al. [ 13–15] developed the so-called shape-memory synthesis (SMS) method for producing porous SiC with surface areas of 10–70 m 2 g −1. The method consists of reacting silicon and SiO 2 at 1200–1500°C to form SiO vapors, which then react with solid carbon to yield porous β -SiC according to Eq. WebA symmetric, informationally complete, positive operator-valued measure (SIC-POVM) is a special case of a generalized measurement on a Hilbert space, used in the field of quantum mechanics.A measurement of the prescribed form satisfies certain defining qualities that makes it an interesting candidate for a "standard quantum measurement", utilized in the …
