Searching for low-cost and efficient catalysts for the oxygen evolution reaction has been actively pursued owing to its importance in clean energy generation and storage. While developing new catalysts is important, tuning the electronic structure of existing catalysts over a wide electrochemical potential range can also offer a new direction. Here we demonstrate a method for electrochemical li...

Abstract Ternary zinc–sodium–phosphate glasses doped with transition metal of the composition Na 2 M x Zn 1− P O 7 ( = 0, 1, and 5 mol %) (where Ni, Cu Co) were prepared by traditional quenching method. The ac conductivity measurements at different temperatures for have been investigated, activation energy dc conduction has determined in each sample. results showed that evolution depends on nat...

the major reason for the prediction of thermodynamic properties of mercury lies in the fact that itsintermolecular interactions highly depend on temperature and density. internal pressure is a good criterion toinvestigate the density dependence of the interatomic interactions. because its physical base is a forcetending to close together the molecules that is intermolecular interactions, and as...

The title compound, [Mn(C(8)H(4)N(8))(2)(H(2)O)(5)]·2H(2)O, is the fourth transition metal complex containing the 1,3-di(2H-tetra-zol-5-yl)benzene ligand to be structurally characterized. The Mn^II^ cation has a distorted octahedral coordination geometry. The 1,3-di(tetra-zol-5-yl)benzene ligand is planar. All H atoms bonded to O atoms participate in hydrogen bonds, which link the mol-ecules in...

α,α-Difluorodiaroylmethane can be used as a nucleophilic difluoromethylation reagent for generating α-thioaryl-α,α-difluoroacetophenones (Ar(1)COCF2SAr) and difluoromethylthiolated arenes (ArSCF2H) under transition-metal-free conditions. The reaction selectivity is mainly dependent on temperature. The method has also been extended to the synthesis of α-thioaryl-α-monofluoroacetophenones using α...

Divalent metal complexes of macrocyclic ligand 1,4,8,11-tetraazacyclotetradecane-1,8-bis(methylphosphonic acid)) (1,8-H4te2p, H4L) were investigated in solution and in the solid state. The majority of transition-metal ions form thermodynamically very stable complexes as a consequence of high affinity for the nitrogen atoms of the ring. On the other hand, complexes with Mn2+, Pb2+ and alkaline e...

Crystal structures and physical properties have been investigated for two cation radical salts formed with EOET, which is a hybrid molecule between ET and BO. The Mott-insulating κ’-(EOET) 2 Cu[N(CN) 2 ]Br salt has a spin-singlet ground state, while the κ-(EOET) 2 GaCl 4 salt with a triangular lattice composed of EOET dimers shows a metal-insulator transition at around 40 K.
