Bending rigidity plays an important role in graphene from mechanical behavior to magnetic and electrical properties. However. it is still in a theoretical debate whether the bending rigidity of graphene increase or decrease with increasing temperature. The liquid membranes renormalization theory is always used to calculate the bending modulus of 2D membrane (graphene) at different tem... https://www.roneverhart.com/Kuiper-Belt-8-Year-Old-Straight-Kentucky-Bourbon/
