Amorphous carbon is free, reactive carbon that has no crystalline structure. Amorphous carbon materials may be stabilized by terminating dangling-π bonds with hydrogen. As with other amorphous solids, some short-range order can be observed. Amorphous carbon is often abbreviated to aC for general … Meer weergeven In mineralogy, amorphous carbon is the name used for coal, carbide-derived carbon, and other impure forms of carbon that are neither graphite nor diamond. In a crystallographic sense, however, the materials … Meer weergeven • Glassy carbon • Diamond-like carbon • Carbon black Meer weergeven With the development of modern thin film deposition and growth techniques in the latter half of the 20th century, such as chemical vapour deposition Meer weergeven Q-carbon, short for quenched carbon, is claimed to be a type of amorphous carbon that is ferromagnetic, electrically conductive, harder than diamond, and able to exhibit high-temperature superconductivity. A research group led by Professor Jagdish Narayan and … Meer weergeven Web1 mei 2024 · Hydrogenated amorphous carbon began to attract attention as a semiconductor mate-rial after a-Si:H had already become the most commonly used …

Co-doped amorphous MoSx for efficient hydrogen evolution …

WebWang et al. anchored Pt on N-doped carbon nanotubes (CNT) as an excellent HER catalyst, performing stable hydrogen production for 100 h at 500 mA cm −2 (overpotential of 107 mV). The excellent stability is attributed to the strong metal-support interaction of the N-doped CNT, which allows the Pt nanoparticles to be uniformly dispersed on the CNT … WebWe define diamondlike carbon~DLC! as amorphous carbon with a significant fraction of sp3 bonds. The hydrogenated amorphous carbons ~a-C:H! have a rather small C-C sp3 content. DLC’s with higher sp3 content are termed tetrahe-dral amorphous carbon ~ta-C! and its hydrogenated analog ta-C:H. Another crucial parameter is the degree of clustering smart be you
