The article presents the results of laboratory studies on effect liquid-gas ratio and foaming agent type average water-air micro dispersion size obtained from solution. microbubbles significantly effects efficiency flotation depends concentration used for their production. A generator was to obtain dispersion. works were performed work out parameters at different performance generator. followin...

Abstract Novel hypercrosslinked polymers nanoparticles (HCPNs) were designed by suspension polymerization technique with high surface area as well HCPNs functional groups have the affinity to removal of copper ions from aqueous solutions. Two synthesized through a two-step reaction, initially including N-methacryloxytetrachlorophthalimide (NMTPA) divinyl benzene (DVB) give poly(NMTPA-co-DVB) an...

Owing to the requirement for environmental protection, water-based coatings have become a significant trend in development of coatings. The epoxy curing agent has also hot research topic. In this study, B-A-B compound with long hydrophobic alkyl chain connected intermediate nitrogen atom was synthesized at both ends molecule using ethylene glycol diglycidyl ether and 3,4-dimethoxyaniline as raw...

Most patients with diabetes die from cardiac or arterial disease, for which there are limited therapeutic options. Free Cu(2+) ions are strongly pro-oxidant, and chelatable-Cu(II) is increased in the diabetic heart. We reported previously that treatment by Cu(II)-selective chelation with triethylenetetramine (TETA) evokes elevated urinary Cu(II) in diabetic rats and humans in whom it also impro...
