Abstract: During the past decade, ionic liquids (ILs) have attracted increasing attention as efficient, novel solvents for dissolving cellulose. In this study, 1-butyl-3-methylimdazolium methylphosphonate ([C4C1im][(OMe)(H)PO2]) was used in the dissolution of cotton cellulose and the role… read more here.

Abstract: The mechanism for dioxygen activation represents one of the core issues in metalloenzymes. In most cases, the activation of the O2 molecule requires additional electrons from an external reducant. However, nonheme hydroxyethylphosphonate dioxygenase (HEPD) and… read more here.
