WebSep 1, 2024 · Lubricant-impregnated surfaces, generally referred to as liquid-impregnated surfaces (LIS), are slippery surfaces that effectively eliminate the no-slip boundary condition, allowing viscous liquids, gels and emulsions to slide freely. Web1 day ago · The configuration of water-hydrazine was generated by inserting water and hydrazine molecular into a cubic box with initial size of 6 nm. It covers from 0 to 1 in steps of 0.1 with an additional point 0.45 near the azeotropic point 0.46 (Burtle, 1952).These boxes were energy minimized and equilibrated at desired temperature to obtain the liquid density.
