Surface roughness was recognized to play a major role in forming friction and transition from one lubrication regime to another [1]. Greenwood pioneered with first rough contact model in 1966 [2]. Inspired by this milestone […]

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 [...]

Superlubricity state through atom-by-atom surface tuning

18.01.2016

Friction is everywhere around us, working against motion of cars, airplanes, their engines, wind mills and other devices causing wear and decreasing their energy and overall performance efficiency. However, there exists a certain state, called [...]
Modeling Ice Friction

Glaciers and Ice Friction Glaciers are comprised of snow accumulated over many years and compressed into large ice masses. Formed when snow remains in a location long enough to form ice, glaciers are unique in [...]
Bio-based material stronger than steel and spider silk altogether

16.05.2018

Researchers at KTH have produced a bio-based material that is reported to surpass the strength of all known bio-based materials whether fabricated or natural, including wood and spider silk. Working with cellulose nanofibre (CNF), the [...]
