Computational Tribology
Nanoscale friction on thin films
22.03.2021 Nikhil Kunapareddy

In nature ‘entities’, either be living or non-living tend to behave differently at different scales by exhibiting different properties. Which play a major role in the way we frame our perspectives and opinions on them. […]

How to make greener ammonia with tribology?
15.03.2021 Jean-David Wheeler

A bit of context Ammonia synthesis is estimated to generate ~1% of the world CO2 emissions [2]. This single molecule is mass produced (~175 Mt) and the Haber-Bosch process employed is fossil fuel hungry! High […]

The physics behind ice skating: A tribological perspective
01.03.2021 Nikhil Kunapareddy

Ever wondered what makes ice so special to skate on it? Apart from freezing your favorite beverages, it helps make life adventurous. Yes, I am talking about sports like ice skating and ice hockey, it’s […]

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 […]

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 […]

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 […]

Programmable Friction: Electrical Regulation of Ionic Liquid Lubrication
23.11.2020 Aydar Akchurin

Friction is a force rising between two surfaces when they move in opposite directions or when one moves over a stationary surface. The scale of the movement does not matter: from the movement of continental […]

Electric vehicles: less challenges for tribologists?
16.11.2020 Jean-David Wheeler

With the last years’ rise of electric vehicles (EV), you may have thought that the future lubrication challenges for cars may not be challenging anymore. At least not as challenging as the ones that the […]

Solving the Problem of Slippery Train Tracks Due to Fallen Leaves
19.10.2020 TriboNet

Friction is the force experienced when two surfaces slide, or try to slide, across each other. We are thankful for friction when we put our foot on the brake to stop the car, or when […]
