Preparation and characterization of novel P(HEA/IA) hydrogels for Cd2+ ion removal from aqueous solution
(Elsevier Science Bv, Amsterdam, 2015)
Series of novel hydrogels based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA), P(HEA/IA) copolymers, were prepared by free radical cross-linking copolymerization and investigated as potential adsorbents for Cd2+ ...
Contributions of impregnated silver nanoparticles to ideality increase of filtration material in human respiratory protection / Doprinos impregnisanih nanočestica srebra porastu idealnosti filtrirajućih sredstava respiratorne zaštite
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
A technical contradiction arises when within a system one parameter improves thus automatically causing another one to worsen. In a situation like this, instead of a usual acceptance of compromise which leads to optimization ...
