Reynolds equation is a partial differential equation that describes the flow of a thin lubricant film between two surfaces. It is derived from the Navier-Stokes equations and is one of the fundamental equations of the […]

Molecular Dynamic Simulations and AFM Experiments at Overlapping Speeds

11.04.2016

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 [...]
Phase-Switching Liquids Frost 300 Times Longer Compared to Known Anti-Icing Coatings

08.04.2019

Ice and frost formation on surfaces afflicts various energy and transportation industries worldwide, causing economic losses in billions of dollars annually. Most techniques to prevent frost and ice formation on surfaces rely heavily on heating [...]
Vacuum Has Friction and Soon It Will be Measured

10.02.2020

A team of physicists at Purdue University has created the fastest spinning object ever made, taking them much closer to being able to measure the mysterious friction forces inside vacuum. This object is a small [...]
Can full film occur when Lambda = 0.6?

12.04.2021

The holy grail of tribologists studying lubricated systems is often to predict the contact lifespan. For this purpose, you can compute the minimum film thickness separating the two bodies… but only if you make the [...]
Tribology and the Human Evolution

12.08.2019

Tribology, not a common household word, is the science of wear, friction, and lubrication, studying how interacting surfaces behave in relative motion. Tribology does not work in isolation but affects a multitude of other fields [...]
