Sol-gel Long Lasting Power These long-lasting and significantly safer batteries are novel because of their sol-gel base. A uniform carbon coating process produces high-performance lithium-ion batteries. This method makes use of organic phosphoric acid as carbon and phosphoric sources to produce

Biosurfactants produced by Pseudomonas aeruginosa SB24 (rhamnolipid congeners), Bacillus amyloliquefaciens ST34 (surfactin and bacillomycin L analogues and homologues) and pigmented (P1) and non-pigmented (NP1) Serratia marcescens strains (serratamolide and glucosamine derivative homologues) were
