Switchable Friction on Graphene

15.08.2016 Aydar Akchurin

Graphene is a unique material in many aspects and has recently been applied in various ways. In tribology, it has been shown to lead to a superlubricity – an ultra low friction state. In laboratory […]

Biodegradable Triboelectric Nanogenerators to Power Implantable Sensors

15.06.2020

Energy harvesting (also sometimes called scavenging) is a process of energy derivation from the ambient sources, e.g., sunlight, wind, heat, mechanical vibrations, etc. The main idea is that devices can collect the energy present in [...]
Friction and Wear: From Elementary Mechanisms to Macroscopic Behavior

23.09.2019

In the last 25 years, the global trend to miniaturization has raised interest in frictional processes on the micro and nano scale and facilitated appearance of nanotribology as a new branch of research. Soon it [...]

Sticky toe pads of lizards and evolution

31.10.2017

Gecko hanging on glass by one foot Travis Hagey, Michigan State University evolutionary biologist, shows how different groups of lizards – geckos and anoles – took two completely different evolutionary paths to developing the beneficial [...]
Superlubricity by means of repulsive van der Waals forces

06.04.2016

Superlubricity, a state of low friction (<0.001), can be achieved by different mechanisms. The structural superlubricity occurs, if the crystal lattices of the contacting bodies are incommensurate. Nano-scrolls may act as a bearing and may [...]
