Colloidal semiconductor nanocrystals present unique optical properties which depend on their size, shape and composition. It is therefore crucial to be able to precisely control these parameters during their synthesis. Here we present the synthesis and the optical properties of two kinds of core/shell heterostructures…
In the title salt, [Pd(C(10)H(8)N(2))(C(6)H(6)NO)(2)](PF(6))(2), the Pd(II) atom is in a slightly distorted square-planar coordination environment by N atoms derived from two 4-pyridine-carboxamide ligands, in a cis disposition, and a chelating 2,2'-bipyridine mol-ecule. The monodentate ligands are nearly orthogonal t…
In the title compound, {[Tb(C(12)H(8)NO(2))(3)(H(2)O)(2)]·H(2)O}(n), the Tb(III) cation is in an eight-coordinate environment, ligated by six carboxylate O atoms from five 3-(pyridin-4-yl)benzoate (L) ligands and by two O atoms from water molecules. The cations are bridged by the carboxylate O atoms of the L ligands t…
Concerning to their industrial application, testing of the performances of nanomaterials is very important . Research of graphene characteristics is important for the storage of hydrogen. In this paper the interaction of the wave packet was simulated with one graphene sheet and the results were studied. Temperature Tf…

La sepiolita es un mineral utilizado en numerosos productos comerciales e industriales generalmente relacionados con aplicaciones de absorción de moléculas orgánicas. Este mineral, por su hábito fibroso, fue utilizado como un sustituto del asbesto. Presenta una estructura tridimensional en fibras que origina una alter…
As the nuclear industry grows around the globe, it brings with it a need for more safeguards and proliferation resistant technologies. The International Atomic Energy Agency (IAEA) depends on effective containment and surveillance (C/S) technologies and methods for maintaining continuity of knowledge over nuclear asse…
Cette thèse possède un double objectif : le premier est l'amélioration des techniques de contrôle en mécanique quantique, et plus particulièrement en RMN, grâce aux techniques du contrôle optimal géométrique. Le second consiste à étudier l'influence des singularités hamiltoniennes dans les systèmes physiques contrôlés…
In the title compound, (C(7)H(11)N(2))[Er(H(2)O)(8)]Cl(4)·H(2)O, the asymmetric unit consists of one 4-(dimethyl-amino)-pyridinium and one octa-aqua-erbium cation balanced by four Cl(-) anions, and one water mol-ecule. The 4-(dimethyl-amino)-pyridinium cation is protonated at the pyridine N atom. The dimethyl-amino gr…
Proposed and justified method of calculating the parameters of functional cavitation devices. It was obtained summarized and calculated dependencies of critical parameters for determining leakage. Using the experimental data are built graphical dependencies for determining the capacity of the holes and nozzles.
This thesis deals with the biological activity of fibronectin (FN) as interface protein in the interaction between cells and materials.It investigates protein response, in terms of adsorbed amount and conformation, to different physicochemical properties of the material.Moreover, early cell response and cellular funct…
Solid iron can be observed at environmental conditions and also as metallic component of quasicrystalline alloys.Its behavior in aqueous solution is analyzed from some particular thermochemical relationships.The model utilizes free Gibbs energy to obtain pH and pε parameters which are related to iron redox reactions.T…
Les complexes de lanthanides, grâce a un temps de decroissance de luminescence eleve, sont parmi les sondes les plus sensibles puisqu’ils permettent une mesure de luminescence en temps resolu. Ces complexes sont a la base de certaines technologies permettant, in vitro et/ou in cellulo, la detection d’interactions entr…
Amino-functional macroporous monoliths from polymerized high internal phase emulsion (polyHIPE) were surface modified with initiators for atom transfer radical polymerization (ATRP). The ATRP initiator groups on the polyHIPE surface were successfully used to initiate activator regeneration by electron transfer (ARGET)…
Moisture transmission properties of some combinations of polyester and viscose blended single jersey fabrics were studied in an effort to understand the physical basis of clothing comfort. In addition to this an attempt has also been made to investigate the influence of enzyme treatment on moisture transmission charac…
Energetic materials comprise a set of systems of tremendous technological importance. Besides helping shape landscapes to establish communications, they have been used to reach fuel reservoirs, deploy safety bags and prevent heart strokes. Understanding its behavior can help in attaining strategic and tactical superio…

Si e testata, inoltre, la risposta di composti organici quali tannini e lign…
A high potential development in organic photovoltaic technology is the production of p-i-n structure, through the controlled doping of the active layer regions close to the electrodes. Here, an opening study on p-i-n structure formation by electrochemical doping with ionic liquids, namely 1-butyl-3-methylimidazolium h…
We propose and experimentally demonstrate novel types of composite sequences of half-wave and quarter-wave polarization retarders, permitting operation at either ultrabroad spectral bandwidth or narrow bandwidth. The retarders are composed of stacked standard half-wave retarders and quarter-wave retarders of equal thi…
Abstract Zinc is a relatively active metal and its compounds are stable. It is found in all natural waters and soils as well as the atmosphere and is an important trace element in plant and animal life. Zinc ores are widely distributed throughout the world: 55 minerals are known. Zinc is a lustrous blue‐white metal an…
