The presence of disorder in crystals gives rise to a diffuse, continuous scattering in diffraction patterns. Disorder, in fact, may cause broadening of Bragg reflections and a decrease of the maximum height of the peak intensity. However, for any Bragg reflection whose intensity is affected by disorder, the intensity…
Hybrides nano /micrométriques de nanotubes de carbone (NTC) greffés sur microparticules d alumina, microplaques de SiC ou nanoplaquettes de graphène (NPG) ont été utilisés comme renforts multifonctionnelles dans les composites à matrice polymère. Le NTCs utilisés étaient généralement sous forme de six branches symétri…
La compréhension usuelle de l'appariement proton-neutron, dont les traces sont actuellement étudiées en noyaux N = Z, s'appuie sur le mécanisme de paires de Cooper et modèles BCS type. Dans cette thèse, nous présentons une approche alternative qui, contrairement aux modèles BCS, conserve exactement le nombre de partic…
La lyophilisation est un processus industriel utilise pour ameliorer la stabilite de produits biopharmaceutiques tres labiles en solution et pendant leur stockage. Il s'agit d'un procede tres consommateur en temps et energie (sur plusieurs jours s'il n'est pas optimise). Les phenomenes physiques associes a ce processu…
The light effect on specific growth rate of the seven species dinoflagellates Prorocentrum cordatum, P. micans, P. pusillum, Gyrodinium fissum, Glenodinium foliaceum, Scrippsiella trochoidea and Heterocapsa triquetra on the light intensities from 10 to 344 μmol m-2s-1 was investigated. Found that at 19 – 22 o C and a…
Les composants du circuit primaire des réacteurs nucléaires à eau sous pression (REP) subissent une corrosion généralisée entraînant le relâchement d'espèces solubles dans le fluide primaire (principalement Fe, Ni, Cr, Mn, Co). Sous l'effet de la convection du fluide, ces espèces sont entraînées dans le circuit primai…

The Host-Guest complexation of 5,17-bis-(N-tolyliminomethyl)-25,27-dipropoxycalix[4]arene with benzoic acids has been studied by reversed-phase high-performance liquid chromatography (RP HPLC) method (the mobile phase – MeCN/H2O, 86/14 v/v, the column support – LiChrosorb RP 18, UV detector, l = 254 nm). The study of…
Циљ овог истраживања је да се испита примене „cross-flow“ микрофилтрације на oбраду џибре од скробних сировина и утицај оперативних параметара (рН, трансмембрански притисак и проток) на флукс пермеата и ефикасност пречишћавања у систему са и без присуства статичког мешача. Микрофилтрација је изведена у условима потпун…
This bachelor thesis summarizes the most commonly used species concepts in the class Zygnematophyceae. This group of algae and the molecular markers used in the zygnematophytes' molecular phylogeny will be presented in this thesis. Zygnematophytes have unicellular or multicellular forms and they generally occur in fre…

The pyrochlore compounds Ho2Ti2O7 and Dy2Ti2O7 show an exotic form of magnetism called the spin ice state, resulting from the interplay between geometrical frustration and ferromagnetic coupling. A fascinating feature of this state is the appearance of magnetic monopoles as emergent excitations above the degenerate gr…
We have been examining factors determining the accuracy of cluster expansion (CE), which is used in combination with many density functional theory (DFT) calculations. With the exception of multicomponent metallic or isovalent ionic systems, the contributions of long-range effective cluster interactions (ECIs) to conf…
Oscillator-strength sum rule in light-induced transitions is one general form of quantum-mechanical identities. Although this sum rule is well established in equilibrium photo-physics, an experimental corroboration for the validation of the sum rule in a nonequilibrium regime has been a long-standing unexplored questi…
We compute for an archetypical glass-forming system the excess of particle mobility distributions over the corresponding distribution of dynamic propensity, a quantity that measures the tendency of the particles to be mobile and reflects the local structural constraints. This enables us to demonstrate that, on superco…

In order to investigate the influence of stabilization treatment on microstructure and intergranular corrosion(IGC) resistance of Super304H austenitic heat-resistant steel,the microstructure including grain size,carbide distribution,type and amount of the samples after solution and stabilization treatment were charact…
This work reports the study of semiconductor nanocrystals, also known as quantum dots, focusing specifically on zinc sulfide (ZnS). Two different capping agents were used (glutathione and N-acetyl-L-cysteine) for the preparation of ZnS nanocrystals via aqueous route. The study aimed specifically at evaluating the effi…
a-Al2O3 powders with different shapes were prepared from the reaction of aluminum sulfate octadecahydrate and urea by hydrothermal pyrolysis method.The as-prepared products were characterized by X-ray diffraction(XRD) and scanning electron microscopy(SEM).The effects of reaction time and additives such as PEG 2000 and…
A two-step method was used to synthesize a novel biodegradable polyurethane(PU) composed by L-lysine ethyl ester diisocyanate(LDI),poly(e-caprolactone) diols(PCL-diol) and 1,4: 3,6-dianhydro-D-sorbitol(Isosorbide) as chain extender.3D porous PU scaffolds were produced by a combined salt leaching-phase inverse techniqu…
