The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

European Journal of Inorganic Chemistry, EarlyView.Phosphine oxide reduction with silanes is governed by phosphine oxide distortion and silane interaction energies. In R3SiH silanes, NBO analysis reveals that n(O)→σ*(SiR) donation is distributed among several acceptor orbitals, whereas in Ph2RSiH silanes, small electronegative substituents directly bonded to silicon (RCl, OCN, OH) enhance the σ ...

Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND Recombinant protein expression in Escherichia coli frequently results in the formation of inclusion bodies (IBs), which provide high protein accumulation but often require additional steps to recover functional protein. Although culture conditions strongly influence IB physicochemical and structural characteristics, the impact of ...
