WebApr 13, 2024 · The high-pressure carbon phases beyond diamond are elusive, though, making their discovery a challenge. For example, the first “superdense” post-diamond carbon phase, called BC8, exists only in theory. Research dating back to the 1980s suggests that under extreme pressure, diamond can transform to BC8, which has even higher … WebFeb 7, 2024 · The first one is considered as a graphene structure, which comprised of various layered sheets of sp 2 hybridized carbon with lateral dimensions lower than 10 nm. 11 In contrast, CQDs are similar to amorphous carbon which consist of a disordered sp 2 and sp 3 hybridized carbon structure with physical dimensions lower than 10 nm. 12
