Baking sodium out of a boride leaves a porous boron 10 million times more conductive than common boron
Chemists baked the sodium out of sodium boride to make Imma-B60, a porous boron that conducts about 10 million times better than the common form. Its flexibility figure is shakier, given in the same report as both 23% and 32% strain, the higher from compressing nanopillars.
