‘Switchable solvent’ technology is a promising development for advancing forward osmosis

Forward osmosis (FO), whereby a concentrated salt solution is used to “draw” water through a membrane from a less-concentrated salt solution (via osmotic pressure), has the advantage over reverse osmosis (RO) in that high pressures, with the associated pumps and…

Liquid-infused surfaces move toward commercial applications

A set of technologies that create an immobilized thin layer of lubricant on a solid surface, thus enabling highly repellent, omniphobic surfaces, has moved closer to commercial application. Known as slippery, liquid-infused porous surfaces (SLIPS), the technologies can be applied…

A booster bed for Circulating Fluidized-bed Combustors

The efficiency of circulating fluidized-bed (CFB) combustors can be significantly increased by substituting conventional bed material with an ilmenite-based bed material, according to researchers at Chalmers University of Technology (Gothenburg, Sweden; www.chalmers.se). Conventional CFB boilers use silica sand to evenly…
