The pore-load modulus of ordered nanoporous materials with surface effects
AIP Advances, 2016 Gas and liquid adsorption-induced deformation of ordered porous materials is an important physical phenomenon with a wide range of applications. In general, the deformation can be characterized by the pore-load modulus and, when the pore size reduces to ...

Robust structural superlubricity under gigapascal pressures
Nature CommunicationsStructural superlubricity (SSL) is a state of contact with no wear and ultralow friction. SSL has been characterized at contact with van der Waals (vdW) layered materials, while its stability under extreme loading conditions has not been assessed.
