Researchers from China’s Lanzhou Institute of Chemical Physics (Chinese Academy of Sciences) have observed the quantum friction phenomenon at solid-solid interfaces for the first time, making a significant breakthrough in quantum friction research. By folding graphene sheets, the researchers induced internal strain that altered how electrons moved through the material.
The nature and mechanism of friction are seen as core scientific questions – especially at the microscopic level. Scientists long believed it arose from rough surfaces rubbing together, where tiny bumps and sticky spots resisted motion and transformed energy into heat. The researchers utilized nanomanipulation techniques to construct folded graphene edge topological structures with controllable curvature and layer numbers. Systematic measurements of nanoscale friction were conducted.
