Elastohydrodynamic Lubrication (EHL): Theory and Definition

05.02.2017 tribonet

Definition of Elastohydrodynamic Lubrication (EHL) Elastohydrodynamic Lubrication – or EHL – is a lubrication regime (a type of hydrodynamic lubrication (HL)) in which significant elastic deformation of the surfaces takes place and it considerably alters […]

Triboelectricity to collect wave power

01.06.2017

Nature provides three sources of energy for free: sunlight, air and gravity. Solar and wind power are increasingly exploited, gravity less so. Hydraulic power plants harvest energy from flowing rivers. Tidal energy can be gathered [...]
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 [...]
Graphene vs. MoS2: Which One Has Lower Friction?

26.08.2019

Two-dimensional (2D) materials, layered structures having atomic- to nano-scale thickness, have shown unique physical properties such as high in-plane stiffness combined with extremely low out of plane bending rigidity. 2D materials have been used in [...]

Leonardo di ser Piero da Vinci, the famous Italian engineer, architect, painter, musician, mathematician can also be considered as The First Tribologist! Although the term itself was invented approximately 450 years after Leonardo da Vinci [...]
The science of slippery bananas

24.11.2017

They’re yellow. They’re radioactive. And they’re very slippery. Yes, they’re bananas, and we have just found out why they’re so slippery. So yellow … yes we all know that. But radioactive? Well yes, bananas are [...]
