Experimental measurement of adhesion and friction in mesoscopic graphite contacts

07.02.2016

Two-dimensional materials, such as graphite, expose an intriguing, but poorly understood low-friction behavior – superlubricity. Various aspects of superlubricity have been addressed by researchers, mostly based on theoretical considerations, however, accurate experimental measurements of adhesion [...]
Contact Area Calculation Tutorial: Boundary Element Based Model vs. Asperity Based Model

14.03.2018

In contact mechanics and tribology it is frequently needed to calculate the contact area between rough surfaces to estimate possible slip, friction, electric conductivity, etc. In this tutorial, it will be shown how to perform [...]

Individuals who deal with the health of animals on a regular basis are keenly interested in understanding the wear processes that affect the teeth of herbivores. Understanding these wear processes will potentially lead to the [...]
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 [...]
In Situ Nanopolishing (ISN): A New Lubrication Paradigm Aimed at Permanent Surface Perfection

23.04.2016

All conventional lubricants borne of classic hydrodynamic theory are designed to provide lubricity. Inherent in the desire to provide lubricity to mechanical systems is the desire to protect the interacting metal surfaces from wear. Much [...]
