Unlike traditional lab-based methods, the GranuCharge AL provides instant access to the charge per mass measurement thanks to its integrated load cell combined with a Faraday cup connected to a highly ...

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 ...

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 ...
