Europium(III) derivative formed by reaction of the europium ion with a fluorinated diketonate reagent and a neutral donor. The resulting non-polar, thermally stable, and luminescent derivative partitions into cyclohexane upon formation and can be subjected to high-resolution capillary gas chromatography. This approach…

Vapor Multifold Nucleation Rate Surfaces for Case of the Polimorfous Enantiotropic Phase Transitions of a Condenced Phase
Examples of the nucleation rate topologies for systems which are having the enantiotropy polymorphic phase transitions, using the idea of the nucleation rate surface semiempirical design over the phase equilibria diagrams, are presented. It was shown that multichannel vapor nucleation in according the independent set…
Semiempirical Method of Boiling Expectation Time Calculation in Falling Wavy Liquid Film
The Mathematical model which allows to calculate boiling expectation times in falling wavy liquid films on nonsteady heat release has been represented. It has been shown that it is necessary to take a convective constituent of a heat transfer into account in heat exchange modeling in falling films. The effective therm…
Structure, Ionic Conduction and Thermodynamics of New Compounds Based on Bismuth and Renium Oxides
New compounds Bi14ReO24.5, Bi12.5Lu1.5ReO24.5, Bi12.5Ho1.5ReO24.5 were synthesized by solid-state method with bismuth oxide, Bi2O3, ammonium perrhenate, NH4ReO4, lutecium oxide, Lu2O3, and holmium oxide, Ho2O3. The lattice parameters and space group were determined by X-ray diffraction spectroscopy. Bi14ReO24.5 has te…

Transformateur limiteur de courant supraconducteur à haute température critique : design, construction et test
RESUME Malgre un rendement eleve pouvant atteindre 98% ou 99%, les transformateurs modernes avec des enroulements en cuivre ou aluminium generent des pertes d'origines electrique (eet Joule, 80% a pleine charge) mais aussi magnetique ( 20%). L'utilisation de supraconducteurs pour les bobines permettrait, grâce aux pro…
Development and implementation of computer methods at the analysis of the deformation of the beam body with the finite elements method (FEM)
16=111This is a very substantial activity in which designer fi nds out possible deformations, rigidities (stifnesses) and stress states of the machine parts and fi ts after forming its virtual geometry, and later the real one as well.They are of the essential importance at the fast and accurate analysis of the possibl…
An Integrated Chemical Reactor-Heat Exchanger Based on Ammonium Carbamate (POSTPRINT)
Abstract : In this work we present our recent effort in developing a novel heat exchanger based on endothermic chemical reaction (HEX reactor). The proposed HEX reactor is designed to provide additional heat sink capability for aircraft thermal management systems. Ammonium carbamate (AC) which has a decomposition enth…
Inductive Microenvironment for Improved Osseous Integration
Abstract : The ultimate goal of tissue engineering is to address the current organ shortage problem, i.e. development of an alternative therapeutic strategy to autografting and allografting. Several approaches are currently been used to regenerate damaged tissue using the principles of tissue engineering. Among these,…
Influence of substrate temperature on structural and optical properties of SnO2 films
Tin Oxide (SnO2) films have been deposited by spray pyrolysis technique at different substrate temperatures. The effects of substrate temperature on the structural, optical and electrical properties of SnO2 films have been investigated. The XRD result shows a polycrystalline structure for SnO2 films at substrate tempe…
