Our study consisted in the characterization of the superconductingmaterial Pr123 using the acoustic method and the non destructive testing(NDT). Our work was performed at high working frequency of 600MHz.We studied the superconducting bulk system…

Le but de cette étude est d'examiner l'utilisation d'un vent électriquegénéré par une décharge couronne à deux électrodes pour nettoyer lespanneaux photovoltaïques de la poussière. La première électrode est un filalimenté par…

The evolution with temperature of the point defect concentration in thecubic C15-ZrFe 2 Laves phase was investigated in the presence of severalternary additions X (X=V, Y, Tc, Ru). The heats of formation of thedifferent point defects were carried out…

Simulation in terms of enzymatic activity and estimation the process oftransfer of electronic active sites of the compound 2-hydroxyphenyl iminonaphthalen-2-ol (Schiff basis) synthesized have called upon valuablecomputational programs such as the…

Carbon production is growing globally, with energy-related carbonemissions accounting for two-thirds of global emissions. Generatingcarbon-neutral hydrogen from renewable energy is a significantachievement toward a circular economy in this industry.…

The use of renewable energies is one of the solutions to reduce CO 2 in theatmosphere and to satisfy our energy needs. Because, the exploitation offossil energies such as carbon, gas and oil are responsible for thedisruption of the climate system and…

On a étudié les propriétés mécaniques d’un composite formé parl’incorporation d’une charge végétale la poudre d’alfa des régions du sudalgérien (Bou-saada) dans la matrice du composite PP r /kaolin. On aobservé une augmentation de certaines…

Ce travail présente une étude numérique bidimensionnelle des phénomènes de la convection mixtelaminaire des nanofluides dans un canal plan horizontale remplie d’eau et de différents nanoparticules(Cu-eau, Al2O3 -eau) pour une fraction volumique des…

This study focuses on the synthesis and characterization of hydroxyapatitewhich can be used in the biomedical field. The bio-ceramic(hydroxyapatite) was extracted from animal bone after being degreased,cleaned and ground into fine particles of…

In the 21 st decade, nanotechnology is back bone of research. Thesenanoparticles have special attention in the all area of world. The particlestructures manipulation rang from 1-100nm and has high properties canbe synthesis by different methods.…
