WebNeutron moderator. In nuclear engineering, a neutron moderator is a medium that reduces the speed of fast neutrons, ideally without capturing any, leaving them as thermal neutrons with only minimal (thermal) kinetic energy. These thermal neutrons are immensely more susceptible than fast neutrons to propagate a nuclear chain reaction of uranium ...

Graphene is an amazingly pure substance, thanks largely to its simple, orderly structure based on tight, regular, atomic bonding. Graphene is pure carbon. And, because carbon is a nonmetal, you might expect graphene to be one too. In fact, it behaves much more like a metal (though the way it conducts electricity is very ...
