Illustration: Christine Daniloff/MIT and Alexei Bylinkskii A new technique tunes friction between two surfaces, to the point where friction can vanish. MIT researchers developed a frictional interface at the atomic level. The blue corrugated surface [...]
Models Predicting When and How Roads Will Deteriorate

27.01.2020
Heriberto Perez, a researcher at the UPV/EHU’s Faculty of Engineering-Bilbao, has developed behavior models able to predict the future deterioration of roads. The models focus on two different aspects, the international roughness index (IRI) and [...]
Friction Forces Between 2D Materials and Liquids

By Dr. Ameneh Schneider – Optimol Instruments GmbH and Dr. Mathias Woydt – MATRILUB Introduction Interest in special coatings and thin films for tribological applications increased rapidly in the last few decades, especially driven by [...]
Hysteresis in Friction of Graphene

02.05.2016
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 [...]
