Durable drag reduction and anti-corrosion for liquid flows inside lubricant-infused aluminum/copper capillaries

Frictional drag reduction and anti-corrosion for the liquid flows in micro- and nanochannels result in considerable economic and environmental benefits. The lubricant infused surface (LIS) has emerged as a promising technology for achieving the two functionalities. This work proposes the fabrication...
