Electrostatic adsorption is an important complement to mechanical filtration for high-efficiency air filtering in the use of face masks. However, the electrostatic charge of the filters decays over ...

As renewable energy storage demand grows, the limitations of aqueous zinc metal batteries (AZMBs) in subzero environments become more pronounced. Now, researchers from Harbin University of Science and ...

Researchers have engineered an electrostatic face mask that can 'self-charge' through the user's breathing and continuously replenish its electrostatic charge as the user wears and breathes through ...
