We report a carbon-boron clathrate with composition 2 La@B6 C6 (LaB3 C3 ). Like recently reported SrB3 C3 ,[1] single-crystal X-ray diffraction and computational modelling indicate that the isostructural La member crystallizes in the cubic bipartite

Carbon-based frameworks composed of sp3 bonding represent a class of extremely lightweight strong materials, but only diamond and a handful of other compounds exist despite numerous predictions. Thus, there remains a large gap between the number of p

Pressure-induced structural changes in a sodium borate glass have been studied up to ~ 9 GPa by in situ micro-Raman spectroscopy in a diamond anvil cell at ambient temperature. The results show a decrease in the fraction of boroxol rings and an incre
