Friction rises when bodies come to contact and start relative sliding. This phenomenon occurs in many mechanical systems and it is estimated that over 30% of the fuel in cars is consumed to overcome [...]
Friction Forces Between 2D Materials and Liquids

25.05.2020

2D materials deserved an interest in material science and other disciplines due to their exciting electronic, mechanical, and optical properties. The unique behavior of these materials originate from very strong in-plane atoms interactions and very [...]
Does Friction cause Friction Blisters?

25.07.2017

What is friction? There is more than one definition of friction. And this has confused our understanding of how it is involved in friction blister formation. The Merriam-Webster Dictionary has two definitions of friction: the act of [...]
