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 ...

Last week, Beijing responded to American criticism of its protection of the clean energy products sector with a complaint before the World Trade Organization, alleging that the United States ...

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 ...

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 ...
