The title Sm(III) compound, {[Sm(C(9)H(7)O(3))(3)(H(2)O)]·H(2)O}(n), was obtained under hydrothermal conditions. Its structure is isotypic with the analogous Eu complex. The latter was reported incorrectly in space group P1 by Yan et al. [J. Mol. Struct. (2008), 891, 298-304]. This was corrected by Marsh [Acta Cryst.…
In subwavelength-sized particles, light-induced multipole moments of orders higher than the electric dipole are usually negligibly small, which allows for the light-matter interaction to be accurately treated within the electric dipole approximation. In this work we show that in a specially designed meta-atom, a disc…
As a promising clean fuel for vehicles, hydrogen can be used for propulsion, either directly or in fuel cells. Hydrogen storage compositions having high storage capacity, good dehydrogenation kinetics, and hydrogen release and uptake reactions which are reversible are disclosed and described. Generally a hydrogen stor…

The energies arising from the rotation of free hydroxyl groups in the central glucose residue of a cellulose crystalline assembly, calculated using RHF, DFT, and FMO2/MP2 methods, will be presented. In addition, interactions of this central glucose residue with some of the surrounding residues (selected on the basis o…
Dans le domaine des couches minces (épaisseur~Å) associant un métal magnétique (Fe, Co, Ni) et un élément non magnétique (essentiellement métallique ou isolant), de remarquables propriétés physiques (aimantation, transport) nécessitent des caractérisations structurales fines. En particulier, citons le cas de jonctions…
This chapter introduces the fundamental requirements for measuring radiometric quantities with arbitrary sensors and gives an overview of the basic measuring principles. The radiometric quantities of optical materials, components and systems generally have to be measured dependent on of the wavelength. Instruments whi…

Facultade de Fisica Departamento de Fisica Aplicada Doctor of Philosophy by Jorge Botana Alcalde We have studied several low-dimensionality systems using ab initio techniques, based on the DFT approximation; said techniques have become in the recent times one primary path of theoretical research in solid state physics…
Abstract The current theory of the titled phenomenon is apparently based on an inconsistent use of concentration units, as employed in the derivation of the fundamental equations. Thus, manifestly, whilst the relation between extent of conversion and e.e. is derived with mole fractions, the succeeding kinetic equation…

This thesis presents scanning tunneling spectroscopy (STS) measurements of the spatial distribution of the density of states (DOS) of materials where electron correlations play a role. \nIn the manganite La0.67Ca0.33MnO3, the measurements show that flat films with atomically smooth terraces are electronically homogene…
Los materiales compuestos de matriz polimérica representan una interesante alternativa para el diseño de equipamiento y aplicaciones estructurales. Las atractivas propiedades de polímeros termoestables reforzados con fibras de vidrio han despertado gran interés al tratarse de materiales con precio competitivo, buenas…
Laser welding and post weld laser treatment of modified 9Cr-1MoVNb steels (Grade P91) were performed in this preliminary study to investigate the feasibility of using laser welding process as a potential alternative to arc welding methods for solving the Type IV cracking problem in P91 steel welds. The mechanical and…

Shock initiation in a plastic-bonded explosives (PBX) is due to hot spots. Current reactive burn models are based, at least heuristically, on the ignition and growth concept. The ignition phase occurs when a small localized region of high temperature (or hot spot) burns on a fast time scale. This is followed by a grow…
