Imagine a world where your clothing generates electricity as you move—no batteries, no chargers, just energy from motion.

When friction acts between two surfaces that are moving over each other, some kinetic energy is transformed into heat energy. Friction can sometimes be useful. For example, we rely on the soles of ...

It is irreversible because fluids have viscosity, and whenever velocity gradients appear in the flow there will be friction and energy dissipation due to viscous stresses. The flow can be reversible ...

When friction acts between two surfaces that are moving over each other, some kinetic energy is transformed into thermal (heat) energy. Friction can sometimes be useful. For example, we rely on ...

The recent developments in understanding friction and the leading factors that determine the frictional response at the nanoscale (see Fig. 1), were the main topics of debate at the recent Trends ...

A molecular membrane that allows select ions to cross with almost no friction could significantly ... to the world’s transition to clean energy. “Ion exchange membranes play an increasingly ...

Triboelectric nanogenerators (TENGs) generate electricity through friction between different ... Advancements in triboelectrification could enable new energy-harvesting applications without ...

Ultrasound can reduce friction in deep drawing and thus protect tools and materials. The energy-saving potential resulting from lower forces is something manufacturers of pipes and fittings ...
