In this work, the voltammetric charge and work function of Rh catalyst were studied to clarify the origin of electrochem. promotion. The measures were carried on at 375 Deg, either in a non-reactive oxygen/helium gas mixt. or under complete oxidn. of propy ...
Titanium-containing amorphous hydrogenated carbon films (a-C:H/Ti) have been deposited by a medium-frequency-driven physical vapor deposition plasma-enhanced chemical-vapor deposition process at 40 kHz. Core-level photoelectron spectroscopy and valence-ban ...
The present thesis is devoted to a detailed study of the Casimir force exerting between two parallel metallic plates whose conducting behaviour is described on the microscopic level. In the semi-classical regime, which corresponds to large separations and ...
In plane wave based electronic structure calcns. the interaction of core and valence electrons is usually represented by at. effective core potentials. They are constructed in such a way that the shape of the at. valence orbitals outside a certain core rad ...
The charge density of urea is studied using very high precision single-crystal synchrotron-radiation diffraction data collected at the Swiss-Norwegian Beam Lines at ESRF. An unprecedented resolution of 1.44 Å-1 in sin[theta][/][lambda] is obtained at 123 K ...
Organic light emitting devices (OLED) are among the most promising future technologies for the manufacture of flat and inexpensive displays. Although OLEDs provide already much higher brightness as compared to liquid crystals devices (LCD), they have a maj ...
Calcns. of 13C nuclear shieldings for low-energy isomers of C36H2x (x = 2,3) suggest that it should be possible to use exptl. 13C shifts, when these become available, to distinguish the isomeric form of the underlying fullerene cage and, in the case of iso ...
We discuss our recently proposed mechanism for the electro-oxidation/reduction on Pt(111) surfaces (J. Electroanal. Chem. 2002, 537, 7) in the presence of sulfuric acid. The bisulfate ion has a large dipole moment and is strongly adsorbed on the positive e ...
For the low-spin t2g6 Ru(OH2)62+ (ΔV⧧ = −0.4 cm3 mol-1) and Rh(OH2)63+ (ΔV⧧ = −4.2 cm3 mol-1) hexaaquaions, the respective Id and Ia water exchange mechanisms had been assigned, mainly on the basis of activation volumes ΔV⧧ and entering ligands effects for ...
Diffusion of Li and Na ions in TiO2, anatase, has been studied using theor. (quantum chem. ab initio periodic Hartree-Fock and a modified semiempirical INDO) as well as electrochem. (chronocoulometry) methods. On the basis of the theor. calcns., the geomet ...
