Computational Tribology
Which is the best texture?
22.02.2021 Jean-David Wheeler

Every so often, a natural texture is discovered and presented as a great texture for tribology purposes! Shark skin, leaf surface, or even snake skin are the most renowned examples. And it is true that […]

Scope of Artificial Intelligence and Machine Learning in Tribology
15.02.2021 Nikhil Kunapareddy

Introduction to AI and ML Right from mobile phone apps which recommend our favorite music to the most sophisticated autonomous vehicles, every device in today’s times is embedded with artificial intelligence and machine learning. Taking […]

control friction in a bearing
General Topics
What is this device?
08.02.2021 Jean-David Wheeler

What if the bearings in the wheels of your future car/bicycle/motorbike was doing more than the normal bearing job? What if it could not only bear the load with minimum friction, but also insure other […]

Atomistic Tribology
An Engineered Salvinia-like Slippery Surface
01.02.2021 TriboNet

The surface properties of materials are often critical because they dictate how they react with their external environment. An important property currently under intense investigation is how surfaces interact with liquids like water. In a […]

Droplet in a capillary
Advanced Materials
In specially coated tubes, the more viscous liquid flows faster
25.01.2021 TriboNet

The rate of flow of different types of fluids moving along pipes has critical ramifications when you consider physiological functions like the cardiovascular system. The speed of blood flow through the heart and its network […]

Introduction to Sealing Technology
18.01.2021 Dr Xavier Borras

Let’s start from the beginning: what is a seal? A device or material that is used to close off or fasten an opening or connection, especially to prevent the escape of a liquid or gas. […]

Static friction
General Topics
Illusion of static friction: Does it really exist?
13.01.2021 TriboNet

Static friction might be an illusion made by the rotation of kinetic friction, even though, since the time of Charles-Augustin de Coulomb (1736–1806), we have believed that there exist two types of solid friction. Nakano […]

Computational Tribology
How to better predict the minimum film thickness of elastohydrodynamic contacts?
11.01.2021 Jean-David Wheeler

Let’s say you have the choice between an almost infinite lifespan device, and a device that undergoes wear and failure within a few minutes or hours of running. In most cases, you would choose the […]

MEMS nanofiber
Advanced Materials
Measuring adhesion and friction of polymer nanofibers
04.01.2021 TriboNet

Nanofibers are tiny fibers with diameters measured in the nanometer range. They can be generated by a variety of methods, from various different polymers, therefore they can exhibit different physical properties with different application potentials. […]

Can we please get rid of the toxic copper in brake pads?
21.12.2020 Jean-David Wheeler

Whatever humanity does today, it does it on a very large scale. And the consequences are large as well! In the automotive area, I was clearly aware of CO2 emissions and global warming issues. A […]
