Generating electricity through friction
17.05.2021 Nikhil Kunapareddy

Electricity is considered as a basic necessity for humans just like food, water and shelter. Ironically, if we think about it we need electricity to make food, water and shelter nowadays. In its early days, […]

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 […]

Biodegradable Triboelectric Nanogenerators to Power Implantable Sensors
15.06.2020 Aydar

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 […]

  • Phononic friction dissipation

    How do phonons lead to frictional energy dissipation?

    18.12.2019
    Friction is often associated with the generation of vibrations in the solids that are sliding over each other. Mathematically, these vibrations are described by the phonons in the two solids, the vibrational eigenmodes. Here, we [...]
