Surprisingly, when two lubricated solids are heavily loaded against one another and when a motion is applied to the solids surfaces, these two solids may not be touching one another (see Figure 1, left)! This […]

Researchers discover surface of 'ultra-smooth' nanomaterial steeper than Austrian Alps

17.01.2019

People can usually tell if something is rough or smooth by running their fingers along its surface. But what about things that are too small or too big to run a finger over? The earth [...]
Hydrogen embrittlement in high-strength steels

25.05.2018

Manufacturers of vehicle and machine components often use high-strength steels to save material in lightweight construction and for crash-relevant structural components that require exceptionally high durability. When welding these components, various factors may lead to [...]
Levitated nanoparticles reveal the crucial role of friction in state transitions at nanoscale
