Pt-group metal (PGM) electrocatalysts with unique electronic structures and irreplaceable comprehensive properties play crucial roles in electrocatalysis. Anion engineering can create a series of PGM compounds (such as RuP2, IrP2, PtP2, RuB2, Ru2B3, RuS2, etc.) that provide promising prospect for improving the electrocatalytic performance use noble metals. This review seeks electrochemical acti...

1-In a recent paper* certain properties of the transition metals Ni, Pd, and Pt and of their alloys with Cu, Ag, and Au have been discussed from the point of view of the electron theory of metals based on quantum mechanics. In particular, a qualitative explanation was given of the relatively high electrical resistance of the transition metals. It was shown from an examination of the experimenta...

Two N4-type Schiff base ligands named N,N'-bis(2-pyridylmethylidene)-1,2-diiminoethane (L1) and N,N'-bis(2-pyridylmethylidene)-1,3-diiminopropane (L2) have been synthesized by the reaction of pyridine-2-carbaldehyde with ethylenediamine and propylenediamine, respectively. The binding abilities of L1 and L2 in dichloromethane towards Cu<...

Context: Involvement of reactive oxygen species (ROS) in a variety of physiological and pathological processes has attracted a growing interest. In fact, identification of this global signaling system has provided new insights into underlying pathophysiological mechanisms of various diseases such as Alzheimer’s disease (AD). Understanding this information may lead to the development of novel th...

Minerals are crystalline solids, and their properties are governed by quantum mechanics. Density functional theory in the local density approximation or the generalized gradient approximation gives accurate predictions for energetic properties of closed shell systems, as well as ionic/covalent crystals, and open-shelled transition metals and transition metals oxides. The electronic structure an...

Reductive dechlorination of carbon tetrachloride (CT) and 1,1,1-trichloroethane (1,1,1-TCA) by FeS with transition metals (Cu(II), Co(II), and Ni(II)) and hydrosulfide was characterized in this study. The batch kinetic experiments were conducted by spiking each stock solution of CT and 1,1,1-TCA into 33 g/L of FeS suspensions with and without transition metals at pH 7.5. No significant enhancem...
