Recently, the existence of specimen-size-independent Weibull master curves characterizing strength and failure of macroscopically homogeneous, brittle materials, if the Weibull modulus m > 1, has been demonstrated by the present author. Furthermore, an app ...
IrO2 and boron-doped diamond electrodes were tested by preparative electrolysis of simple model compds. in acid medium. In oxidn. reactions of more complex mechanism than simple electron transfer, these electrodes are active only at potentials of simultane ...
Dendrite tip temperature measurements are reported for the hypereutectic alloy Al-30% Si, directionally solidified as a bulk (non-composite) alloy, and also as the matrix of a fibrous metal matrix composite. Over the range of tip velocities studied (10-100 ...
The adsorption of MeOH on the (110) surface of g-alumina was studied using both ab initio and d. functional theory quantum chem. methods. A [Al3O9H10]+ cluster model comprising one tetrahedral and 2 octahedral Al cations were used to describe the surface a ...
The reaction of NO with CO on a catalyst of 0.5% Pt-3.4% MoO3 supported on a-Al2O3 was studied in different reactors at atm. pressure. A fixed-bed reactor with external recycle loop exhibited bistability and hysteresis as CO concn. or temp. were varied. In ...
The electrochem. oxidn. (or combustion) of orgs. with simultaneous oxygen evolution has been investigated using different oxide electrodes. A simplified mechanism for the electrochem. oxidn. of orgs. is presented, according to which selective oxidn. occurs ...
We report transport measurements on single crystals of Sr2RuO4-δ, grown by the flux technique. The temperature dependence of the Hall coefficient is similar to the one measured in cuprates, and the linear resistivity persists up to ~1000 K, while the super ...
Rotation anisotropy by second harmonic generation (SHG) is carried out on epitaxial Hg1−xCdxTe (MCT) and oxide- and sulphide-covered MCT surfaces and shows the fourfold symmetry pattern expected from the {100} surface (C4v symmetry). The uneven nature of t ...
Nanostructured anatase TiO2 electrodes surface modified with inorg. metal oxide clusters, i.e., phosphotungstic acid (PWA), was studied by XPS and spectroelectrochem. The surface modifiers were electroactive and could be addressed reversibly by changing th ...
