Electronic states and solvation of Cu and Ag aqua ions are investigated by comparing the Cu2+ + e- -> Cu+ and Ag2+ + e- -> Ag+ redox reactions using d. functional-based computational methods. The coordination no. of aq. Cu2+ is found to fluctuate between 5 ...
A novel N-heterocyclic tridentate polycarbene ligand has been synthesized and stabilized as its corresponding silver complex. An electronic structure investigation reveals significant pi-bonding interactions within the Ag-carbene unit of the [(TIMEMe)2Ag3] ...
The unexpected but facile prepn. of the Ag salt of the least coordinating [(RO)3Al-F-Al(OR)3]- anion (R = C(CF3)3) by reaction of Ag[Al(OR)4] with one equiv. of PCl3 is described. The mechanism of the formation of Ag[(RO)3Al-F-Al(OR)3] is explained based o ...
Pure and K-doped vanadia/titania prepared by different methods have been studied in order to elucidate the role of vanadia species (monomeric, polymeric, bulk) in catalytic toluene partial oxidation. The ratio of different vanadia species was controlled by ...
Incorporation of a nitrogen functionality into a tripodal N-heterocyclic carbene ligand system affords the first N-anchored tetradentate tris-carbene ligands TIMENR I (R = Me (5a), t-Bu (5b), Bz (5c)). Treatment of the Me derivatized H3TIMENMe3 imid ...
More than 50 yr. after the proposal of the Dewar-Chatt-Duncanson model for the binding of olefins to transition-metal atoms, the first structurally characterized example of a silver-C2H4 complex [Ag(h2-C2H4)3]+ was obtained with the help of the very weakly ...
Medical-grade poly(vinyl chloride) (PVC) was chemically modified to study how the incorporation of monovalent silver influences Pseudomonas aeruginosa adhesion and colonization. The modification investigated consisted of a radio frequency-oxygen (RF-O-2) g ...
Reactions designed to give Se6[Sb(OTeF5)6]2 by the reaction of Se2Br2, 4Se, and 2Ag[Sb(OTeF5)6] lead to products that include [Ag2(Se6)(SO2)2][Sb(OTeF5)6]2 (1). The distorted cubic (Ag2Se6+2)n consists of a Se6 mol. bicapped by two silver cations (local D3 ...
The bacterial inactivation efficiencies of silver metal and oxides and their combinations on textile fabrics was investigated to evaluate the disinfectant action on airborne bacteria. The inactivation performance was seen to depend on the amount of silver ...
The assisted transfer of silver ion, Ag+, by complexation of Ag+ with the tetrakis(4-chlorophenyl)borate (TPBCl−) anion was studied at the interface between two immiscible electrolyte solutions (ITIES). The elucidation of the interfacial mechanisms employe ...
