Using electrodeposition from a bath of molten fluorides, single crystals of tetragonal beta-tantalum have been obtained for the first time at normal pressure. The unit-cell parameters are a = 10.211 (3), c = 5.3064 (10) Angstrom, space group P (4) over bar ...
CsI thin film photocathodes of 600 nm thickness deposited on polished Al surfaces by resistive evaporation technique were studied by angle-resolved X-ray photoelectron spectroscopy (ARXPS), before and after UV-irradiation under vacuum. It is shown that the ...
The ionic liquid crystal [C12-mim]Cl has been doped with 5 mol% europium nitrate and the photophysical properties of both the ionic liquid and the trivalent europium ion have been monitored with respect to temperature in the range of 248 to +120 uC. The re ...
A detailed three-dimensional, continuous-energy MCNP4B model of the LWR-PROTEUS critical facility has been developed for the analysis of whole-reactor characteristics using ENDF/B-V, ENDF/B-VI and JEF-2.2 cross-section sets. The model has been applied to t ...
Phosphorescent composition comprises an alkaline earth metal silicate doped with europium fluoride and another lanthanide fluoride. Independent claims are also included for: (1) producing a composition as above by grinding a mixture of alkaline earth metal ...
The homoditopic ligand H2LC3 has been designed to form neutral triple-stranded bimetallic helicates of overall composition [Ln2(LC3)3]. The grafting of the polyoxyethylene fragments ensures water solubility and also favors cell penetration whi ...
We performed bulk-sensitive x-ray absorption (XAS) in the partial fluorescence yield (PFY) mode, and resonant x-ray emission (RXES) measurements of the solid solution Sc (7 at.%):Ce at the Ce L-3 (2p-->5d) and M-4,M-5 (3d-->4f) absorption edges. We deduce ...
The present thesis work deals with the investigation of the heterogeneous reactions involving nitrate radical (NO3), dinitrogen pentoxide (N2O5) and ozone (O3) on surrogates of atmospheric mineral dust particles characteristic of the troposphere. An additi ...
The influence of hydrostatic pressure on the emission and absorption spectra measured for various types of InGaN structures (epilayers, quantum wells, and quantum dots) is studied. While the known pressure coefficients of the GaN and InN band gaps are abou ...
The Object Constraint Language (OCL) offers so-called non-deterministic constructs which are often only poorly understood even by OCL experts. They are widely ignored in the OCL literature, their semantics given in the official language description of OCL ...
