A particular salt may precipitate if its solubility product, Ksp, is exceeded. The stoichiometric solubility product of a salt is defined as the product of the molalities of the salt ions in a water solution saturated with salt. The stoichiometric solubility product of CaSO4 is, for example, defined as: K (CaSO ) m ms…
From the beginning of the 1990s to the present, the research focus is on the study of the design of novel catalytic reactors. Micro-reaction engineering is an emerging eld, which is rapidly developing. Several alternative micro-channel catalytic reactors have been recently introduced. The high surface-to-volume ratio,…
We have observed how thermoelectric effects that result in asymmetric melting of silicon wires are suppressed for increasing electric current density (J). The experimental results are investigated using numerical modeling of the self-heating process, which elucidates the relative contributions of the asymmetric thermo…
Yttrium oxide (Y2O3) films have been successfully deposited with yttrium-ethylenediaminetetraacetic acid (EDTA・Y・H) complexes prepared by various milling techniques. The effects of the properties of the EDTA・Y・H complex on the properties of the deposited Y2O3 films have been analyzed. Seven different types of the raw…
Plastics in WEEE (Waste of Electric and Electronic Equipments) have increased up to 25% in the last five years. As new regulations are setting up increased recycling objectives and the oil prize is also increasing, plastic recycling is more than never an issue. In this context, while still working on virgin polymers,…
Aerogels are light and mesoporous materials that appear very promising in terms of thermal insulation. They could play a great part in the future in the reduction of thermal losses through building and appliances envelopes. In this context, the goal of this thesis work is the development of a material combining a very…
This article gives some proposals on how to grow silver nanoparticles using different methods. Dilute silver salts are recommended as the metal precursor starting solutions. The formation of the silver nanoparticles is to be monitored using UV-Vis absorption spectroscopy so as to reveal the formation of silver nanopar…
Supramolecular chemistry has emerged as a vibrant research eld that has provided new approaches to multidisciplinary molecular architecture. An ensemble of molecules organized into higher-order functional structures through weak, non-covalent forces1-3 offers a wide range of nano-and meso-structured assemblies. These…
Enzymes form products from substrates with high selectivity and efciency at ambient temperatures. Enzymes feature well-dened binding pockets that bind substrates during reactions using non-covalent interactions. The behavior is analogous to a lock and key system in which the substrate (key) has a complementary size an…
Ce travail a été réalisé en collaboration avec EDF R&D, dans le cadre d’une convention CIFRE-ANRT, l’objectif étant d’améliorer le coefficient de performance de pompes à chaleur thermoélectriques (PACTEs) pour des "Bâtiments Basse Consommation". Les PACTEs présentent de nombreux avantages environnementaux, le désavant…
Triafulven türevlerinin ve halojen atomları ile komplekslerinin (C3H2=XH2.Y; X=C, Si, Ge, Sn; Y=F, Cl, Br, I) geometrik optimizasyonu B3LYP/6-311+G (d, p) temel setinde yapılarak komplekslerin aromatikliği, geometrik-tabanlı (HOMA), magnetik- tabanlı (NICS ve diamagnetik alınganlık anizotropisi (??) ), ?-elektron sayı…
A Python library for computing integrated information.
The leaf extracts of P. rubra (Kalachuchi), I. aquatica (Kangkong), M. pudica (Makahiya), E. hirta (Gatas-Gatas), and C. aromaticus (Oregano) were screened for inhibitory activity against coagulase production of S. aureus. The Tube Coagulase Test and Colony Count were used for the inhibitory assay. The E. hirta (Gatas…
O objetivo geral deste trabalho foi desenvolver microcapsulas probioticas de Bifidobacterium animalis e Lactobacillus acidophilus avaliando a sobrevivencia dos probioticos microencapsulados sob condicoes gastrointestinais simuladas e a viabilidade durante armazenamento sob diferentes temperaturas, com posterior aplica…
The increasing miniaturisation of MOS transistors has made RAM memories more and more sensitive to alpha particles emitted by radioactive elements naturally present in the materials used for memory fabrication. Indeed, at ground level, the soft error rate triggered by these particles is comparable to that triggered by…

Dizertačná práca sa zaoberá štúdiom morfológie a mechanických vlastností tenkých vrstiev plazmových polymérov na bázi tetravinylsilánu a jeho zmesí s kyslíkom a argónom. Vrstvy boli pripravené na substrátoch z kremíku a skla pomocou metódy plazmochemickej depozície z plynnej fázy. Mikroskopia atomárnych síl bola použi…
Transformers at power on the network can rip current energization which is significantly higher than the rated current of the transformer. Size current energization depends on the time of inclusion and of the remanent magnetism in the core. The currents that occur when you turn on the transformer to the network can so…
L'epuisement progressif des ressources fossiles a entraine ces dernieres annees un transfert d'interet des materiaux synthetiques vers les materiaux issus de ressources renouvelables. Ces derniers peuvent etre elabores a partir de polymeres et/ou de synthons presents dans la biomasse. Dans ce contexte, la synthese de…
Exposure buildup factor (EBF) and energy absorption buildup factor (EABF) for some building materials (cement, clay brick, thermiston, gypsum and ordinary concrete) available in Iraq at the photon energy range 0.015-15.0 MeV up to penetration depth 40 mfp has been calculated using five parameter geometric progression…
