We report in this paper on the electrochemical formation of nickel tetrasulfonated phthalocyanine (NiTSPc) based films on bulk Pt disk microelectrodes (diameter d = 50 μm) and thin-film Pt microdisk (diameter d = 10 μm) arrays for the realisation of Pt bas ...
The dynamic range, sensitivity, and dark decay of holographic recording of wavelength 458 nm in LiNbO3 crystals doped with 0.2-at. % Mn with different oxidation states have been measured. The measured sensitivity is 0.5 cm/J and is found to be independent ...
Fuel Cells are electrochemical devices that are able to directly convert chemical energy to electrical energy, without any Carnot limitation. Hence, their energy efficiencies are relatively high. Among the various types of fuel cells, solid oxide fuel cell ...
Five azo-dyes: 4-phenylazo-phenol, 4-phenylazo-benzeneamine, 4-phenylazo-benzenethiol, 4-phenylazo-benzoic acid, and 4-phenylazo-pyridine have been prepd. and used as a "test kit" for rapid screening of functional group affinity to metal oxides. The dyes w ...
Band-structure (BS) calculations of the density of states (DOS) using the full potential augmented plane waves code WIEN97 were performed on the four single-valence vanadium oxides VO, V2O3, VO2 and V2O5. The DOS are discussed with respect to the distortio ...
The interaction between the dye cis-bis(4,4'-dicarboxy-2,2'-bipyridine)-bis(isothiocyanato) ruthenium(II), Ru(dcbpyH2)2(NCS)2, and nanostructured ZnO was investigated by photoelectron spectroscopy (PES) using synchrotron radiation. The results are compared ...
Three perovskite-type compounds of composition La0.4Ca0.6Fe1-xCoxO3-d (x=o, o.25 and 0.5) were investigated for use as oxygen separation membranes for the partial oxidation (POX) of methane to syngas. Special attention was given to the question of their st ...
Supported photooxidation catalysts containing a metal oxide or metal ion as catalyst which is fixed to the support by means of carboxylate moieties are an alternative to existing such catalysts, particularly if low cost supports such as organic polymers, p ...
Innovative structured catalysts based on nanoparticles of gold supported on activated carbon fibers (ACF) in the form of woven fabrics are presented for low-temperature CO oxidation. Gold was deposited by adsorption from aqueous solution of ethylenediamine ...
Properties of ultra-thin films are different from their single crystal counterparts due to the presence of (substrate induced) strain, different degree and type of (growth induced) disorder and different average doping (distribution of oxygen vacancies, fo ...
