Poly(ethylene glycol) (PEG)-based soft elastomers, bearing tertiary amine and hydroxyl groups, were synthesized in bulk from the epoxy–amine reaction between poly(ethylene diglycidyl ether (PEGDE) a poly(etherdiamine), Jeffamine ED600. High gel fractions (≥0.95) low glass transition temperatures (Tg ≈ −50 °C) attained after complete curing of systems bulk. The amphiphilicity network allowed swe...

chelating resins based on polyacrylonitrile and diethylenetriamine (pan-dta) wereprepared through the simple reaction of polyacrylonitrile with various volume percents ofdiethylenetriamine (dta), (25, 50, 75 and 100). the prepared resins were applied to removeheavy metal ions such as cu(ii), zn(ii) and cd(ii) from aqueous solutions. the sorptionbehaviors of the resins for these metal ions were ...

Symmetry is an intrinsic property of homo-oligomers. Amine oxidases are multidomain homodimeric enzymes that contain one catalytic site per subunit, and share a high homology degree. In this paper, we investigated, by fluorescence spectroscopy measurements, the conformational dynamics resiliency in solutions two amine oxidases, from lentil seedlings, Euphorbia characias latex, which crystallogr...

The ionic liquid A327H+Cl− is generated by reaction of the tertiary amine A327 (industrial mixture tri-octyl and tri-decyl amines) hydrochloric acid solutions. In this study, extraction Au(III) under various variables, including metal concentrations, was investigated. Results indicate that A327H+AuCl4− formed an exothermic (ΔH° = −3 kJ/mol) in organic solution. Aqueous strength influences forma...
