Physicists are one step closer to understand lubrication at nanoscale
The famous picture of transportation of an Egyptian statue to the grave of Tehuti-Hetep, El-Bersheh indicates that the concept of lubrication was already known to ancient Egyptians. The picture below shows how the slaves are dragging a large statue along...
Predicting Engine Oil Behavior Under Extreme Pressure
The Industrial Fluid Properties Simulation Challenge is an open competition designed to push improvements in the field of molecular modeling and ensure simulations are relevant to real world industrial applications. The organizing committee of the challenge want to bridge the...
Slip, No Slip and Cavitation
Engineering surfaces are heterogeneous and can be slippery or sticky locally depending on surface roughness and chemistry. The variation of surface properties affects the interaction between the wall and lubricant and determines friction. Slip can be used to control friction...
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...
