Origins of Friction
A one million dollar question for a tribologist is as follows: where does the friction come from? Despite the undeniable progress in tribology in recent years, this question remains there. But there is a light at the end of the...
Switchable Friction on Graphene
Graphene is a unique material in many aspects and has recently been applied in various ways. In tribology, it has been shown to lead to a superlubricity - an ultra low friction state. In laboratory air, graphene was reported to...
Small Particles – Big Problems
Tiny particles are all over around us and sometimes they may create problems. This is especially of concern with metal particles formed due to wear in man-made engineering devices. Particles formed in car disk brakes may harm lung cells, metal...
Hysteresis in Friction of Graphene
Friction is a result of complex interaction of physical, chemical and mechanical forces at the sliding interface. Due to mentioned complexity, truly predictive models of friction are yet to be developed. As a result of the complexity, various phenomena rise,...
Molecular Dynamic Simulations and AFM Experiments at Overlapping Speeds
Atomic Force Microscopy (AFM) is a powerful and convenient experimental measurement device in the field of nano-scale tribology. It was successfully applied to explore superlubricity in a graphene-gold interface and superlubricity due to repulsive van der Waals forces, to grow...
