It is a long-thought proposal that dense light-element molecular hydrides, such as diborane (B2H6) and methane (CH4), offer an ideal platform to search for phonon-mediated superconductors. However, these hydrides are often unstable under sufficiently high pressure, e.g., B2H6 decomposed into BH and H2 at pressures of above 153 GPa, which are unlikely to exhibit high superconductivity.

AbstractInvestigations into the compositional model of the Earth, particularly the atypical concentrations of volatile elements within the silicate portion of the early Earth, have attracted significant interest due to their pivotal role in elucidating the planet’s evolution and dynamics. To understand the behavior of such volatile elements, an established ‘volatility trend’ has been used to explain the observed depletion of certain volatile elements.

Abstract Cubic BC2N, a superhard material with a slightly lower hardness than diamond, has been synthesized but the determination of its crystal structure has long been elusive, impeding the further understanding of pertinent physics. Here, by employing a first-principles electronic structure framework, we predicted a cubic BC2N crystal structure (dia-BC2N), marking it as the hitherto cubic phase among all previously proposed structures.
