The energetics of dissocn. reactions of S82+ into stoichiometric mixts. of Sn+, n = 2-7, and Sm2+, m = 3, 4, 6, 10, were investigated by the B3PW91 method [6-311+G(3df)//6-311+G*] in the gas phase and in soln., with solvation energies calcd. using the SCIP ...
This thesis is devoted to the study of oxygen reduction reaction catalysed by porphyrins at the interface between two immiscible electrolyte solutions (ITIES). Electrochemical and spectrophotometric techniques are introduced to these interfaces in order to ...
The 22q11.2 deletion syndrome (22q11DS) is a widely recognized genetic model allowing the study of neuroanatomicalvbiomarkers that underlie the risk for developing schizophrenia. Recent advances in magnetic resonance image analysesvenable the examination o ...
Plants have efficient mechanisms for detoxification and sequestration of xenobiotic chemicals and trace elements, basis of any efficient phytoremediation process. However the amount of pollutants that can be accumulated and detoxified without disrupting th ...
Three new cation-cation complexes of pentavalent uranyl, stable with respect to the disproportionation reaction, have been prepared from the reaction of the precursor [(UO 2py 5)(KI 2py 2)] n (1) with the Schiff base ligands salen 2-, acacen 2-, and saloph ...
Arsenic sorption onto aquifer sediments was investigated in anaerobic laboratory batch and column uptake experiments and characterized by As, Fe, and Mn X-ray absorption spectroscopy (XAS) to estimate the extent and mechanism of abiotic sorption and oxidat ...
Upon treating elemental S with [AgSbF6], [AgAl(hfip)4], [AgAl(pftb)4] (hfip = OCH(CF3)2, pftb = OC(CF3)3), [Ag(S8)2][SbF6] (1), [AgS8][Al(hfip)4] (2), and [Ag(S8)2]+[Al(pftb)4]- (3) formed in SO2 (1), CS2 (2), or CH2Cl2 (3). 1-3 Were characterized by singl ...
Simulation of biodegradation of chlorinated solvents in dense non-aqueous phase liquid (DNAPL) source zones requires a model that accounts for the complexity of processes involved and that is consistent with available laboratory studies. This paper describ ...
A disproportionation process of a metastable AlCl solution with a simultaneous ligand exchange-Cl is substituted by N(SiMe(3))(2)-leads to a [Al(69)N(SiMe(3))(2)](3-) cluster compound that can be regarded as an intermediate on the way to bulk metal f ...
