Carbon Dioxide Absorption By Boron Nitride Foam

A light foam created from two-dimensional sheets of hexagonal boron nitride by materials scientists at Rice University absorbs carbon dioxide. They discovered freeze-drying hexagonal-boron nitride (h-BN) transformed it into a macro-scale foam that disintegrates in liquids. But adding a bit of polyvinyl alcohol (PVA) into the mix turned it into a far more robust and useful material.

Nanographene Warped Form of Carbon Discovered

The first instance of a new form of carbon has been synthesized by chemists at Boston College and Nagoya University in Japan. This novel material is made up of identical multiple pieces of grossly warped graphene. Each piece contains exactly 80 carbon atoms joined together in a network of 26 rings, with 30 hydrogen atoms around the rim. Since they measure little more than a nanometer across, the individual molecules are referred to as “nanocarbons,” or more specifically in this case as “grossly warped nanographenes. [Read More]
