THEORETICAL STUDY OF STABILITY OF COMPOSITE BASED ON CARBON NANOTUBES AND RUTILE
With the help of quantum and chemical method of close coupling, finding of stable configuration of nanocomposite on the basis of "carbon nanotube and ceramics"is carried out. Rutile nanoparticle with surface (110) consisting of 148 atoms was considered as ceramic material. The criterion for stability was the enthalpy…
SPECTRAL INVESTIGATIONS OF NANOCOMPOSITES ON THE BASIS OF POROUS SILICON
The results of experimental studies of porous silicon nanocomposites with biological materials: powder mineral phase of bone (hydroxyapatite) and biochemical solution identical to the natural tear fluid are presented in the work. Layers of porous silicon have been obtained in the process of electrochemical etching sil…
MECHANISMS OF DEGRADATION OF ELECTROPHYSICAL CHARACTERISTICS OF MOS-STRUCTURES WITH HIGH-K DIELECTRICS
Results of study of the processes of change of electrophysical characteristics are presented at various operating modes of MOS-structures and the analysis of the most probable mechanisms of degradation of structures was spent. The gate dielectric was made from rare-earth oxides (high-k dielectrics). The estimation of…
Six-coordinate oxime-imine cobalt(III) complexes with amino acid co-ligands; synthesis and characterisation
In this publication, several six coordinate Co(III)-complexes are reported. The reaction of 2,3-butanedione monoxime with ethylenediamine or o-phenylenediamine in mole ratios of 2:1 gave the tetradentate imine-oxime ligands diaminoethane-N,N`-bis(2-butylidine-3-onedioxime) H2L1 and o-phenylenediamine-N,N`-bis(2-butyli…

Dielectric and Piezoelectric Properties of (Ba0.85Ca0.15)(Ti0.9Zr0.1)O3 Ceramics as a Function of Calcination Temperature
(Ba0.85Ca0.15)(Ti0.9Zr0.1)O3 + 0.04 wt% CeO2 lead-free ceramics were synthesized by conventional sintering process and the effect of calcination temperature on microstructure, dielectric and piezoelectric properties were investigated. Improved piezoelectric properties have been observed at 1,125℃ calcination temperatu…
Method for nonlinear stochastic problem of creep solving for a plane taking into account damage of the material
The analytical method for nonlinear stochastic problem of creep solving for a plane taking into account the damage of the material and the third stage of creep is developed. Determinative creep equations are taken in accordance with the energy version of the nonlinear theory of a viscous flow in a stochastic form. Stoc…

Functional modeling of construction organization in emergency situations Формирование функциональной модели организации строительного производства в условиях чрезвычайной ситуации
The main purpose of construction organization (CO) is putting an object of a required quality into operation within the established time limit with the lowest labor and resources input. This aim remains relevant also in emergency situations. However, apart from the main tasks of CO in emergencies, there are additional…
Mineralogical composition and functionality of clays used for pottery education by physically challenged learners at the Ikwezi-Lokusa Educational Centre, Eastern Cape, South Africa
Clays used for pottery education to physically challenged learners were mineralogically analysed to appraise their suitability both for usage in making pottery products and convenience for the learners. The suitability is alluded to the fact that the clays have undergone basic beneficiation which include grinding, rem…
