Graphene gets cleaned up

Engineers establish the link between oxygen and graphene quality and present an oxygen-free chemical vapor deposition method (OF-CVD) that can reproducibly create high-quality samples for large-scale production. The graphene they synthesized with their…

The case of the missing black holes

Researchers have applied the well-understood and highly verified quantum field theory, usually applied to the study of the very small, to a new target, the early universe. Their exploration led to the conclusion that there ought to be far fewer miniatu…
