Natural Convection of a Nanofluid in a Conical Container

Mahfoud B., Bendjaghlouli A., Bessaïh R., University of Bouira Algeria, DZ

Natural convection is simulated in a truncated cone filled with nanofluid. Inclined walls wall have constant temperature where the heat source is located on the bottom wall of the conical container which is thermally insulated. [...]

SOI-Multi-FinFET: Impact of Fins Number multiplicity on Corner Effect

Moulai Khatir A.N., Guen-Bouazza A., Bouazza B., Guen-Bouazza A., UABT, DZ

SOI-Multifin-FET shows excellent transistor characteristics, ideal sub-threshold swing, low drain induced barrier lowering (DIBL) without pocket implantation and negligible body bias dependency. In this work, we analyzed this combination by a three-dimensional numerical device simulator [...]

Investigation of the In2O3 oxide grown by electron beam on the In metal and on the InP

Hamaidaa K., Bouslamaa M., Ghaffour M., Ouerdane A., Lounis Z., Ia A.A.S.S.A.L., Nouri A., Besahraoui F., Nouri A., university of temouchent, DZ

Our results are based on the use of the analysis techniques such as the Auger Electron Spectroscopy (AES) and the Electron Energy Loss Spectroscopy (EELS) which are well appropriated to study the surface of point [...]

Eddy Current and Microwave Characterization of Fe- Based Alloy Synthesized by Mechanical Alloying

Hamlati Z., Bergheul S., Azzaz M., University of Saad Dahleb, DZ

In the present study mechanical alloying has been used to obtain bulk nanocrystalline FeAl intermetallic compound. Nanocrystalline powder of Fe(Al) solid solution was the product of ball milling. The structural effects of mechanical alloying of [...]

Enhancement of photoelectrochemical and optical characteristics using a TiO2 nanoparticles interlayer in MEH-PPV heterojunction devices

Habelhames F., Girtan M., Manole A., Lamiri L., Zerguine W., Nessark B., Univesité Ferhat Abbas, DZ

In this work, MEH-PPV+TiO2 composite material was prepared by incorporation of titanium oxide nonoparticles (TiO2) into poly[2-methoxy-5-(2'-ethylhexyloxy)-p-phenylenevinylene] (MEH-PPV) polymer matrix and deposited by spin coating on glass and indium thin oxide (ITO) substrates. The absorbance [...]
