WebThe general process of producing nanoscrolls consists of rolling up planar (or quasi-planar) structures into papyrus- like configurations. The competing forces involved are the elas- tic deformations and the van der Waals interactions. Depend- ing on some parameters, the scroll can even be more stable than the planar parent structure. technic building block setsWebX.H. Shi, Y. Cheng, N.M. Pugno and H.J.
