Researchers have struggled to create an accurate phase diagram of carbon for over 100 years. Now, two researchers from Russia explored melting of graphite and graphene and confirmed some previous hypotheses—and revealed graphene “melting” is in fact sublimation.

Different research groups have measured different values for bending stiffness in graphene that span across orders of magnitude. Researchers led by the University of Illinois at Urbana-Champaign now say the different values stem from the fact that graphene becomes softer the more you bend it.
