Prevention of biofouling in seawater desalination via initiated chemical vapor deposition (iCVD)
Biofouling, the undesirable settlement and growth of organisms, occurs immediately when a clean surface is immersed in natural seawater. It is a universal problem and the bottleneck for seawater desalination, which reduces both the yield and the quality of desalted water. Mitigation of fouling in a …

Polysulfone ultrafiltration membranes impregnated with silver nanoparticles show improved biofouling resistance and virus removal
Biofouling and virus penetration are two significant obstacles in water treatment membrane filtration. Biofouling reduces membrane permeability, increases energy costs, and decreases the lifetime of membranes. In order to effectively remove viruses, nanofiltration or reverse osmosis (both high …

Design of anti-biofouling Lubricant-Impregnated Surfaces (LIS) robust to cell-growth-induced instability
… deposition of cells on wetted solids, so-called biofouling, is a serious operational and environmental threat in many underwater and biomedical applications. Over the last decade, Lubricant-Impregnated Surfaces (LIS) has been one of the popular remedies, owing to its unique oil layer that …
