    Abstract: This research aims to synthesize and characterize the PbTiO3 nanofibres by electrospinning technique. PbTiO3 nanofibre was fabricated onto Al-substrate by home-made electrospinning setup. The spinning or running time was set to 20 min. After spinning, subsequent annealing in oxygen and atmospheric ambient was performed at 600°C for 1 h and followed... Show More

    Abstract: Our daily activity is supported with information stored in tiny tips in computers that are invisible by the naked eyes. The stored information of PC and TV broadcasting images displays on lighted phosphor screens. Comfortable images on the phosphor screens for the naked eyes should be equivalent with the daytime scenery under slightly overcastting ... Show More

    Abstract: Steel 42CrMo4, used in the manufacturing of transmission systems (gears), poses problems in service under specific cyclic stress conditions of the operating mode of its bodies. The treatment of ion nitriding during 20 hours with 520°C applied to 42CrMo4 steel in an untreated state (quenched and tempered) led to the formation of a compound layer (mi... Show More

    Abstract: This study relates to the use of the industrial waste as substitute to the natural aggregates. It relates to two types of waste: Crushed glass and waste tires. These wastes were incorporated into concrete for a partial substitution of the aggregates in the proportions of 5%, 10%, 15%, 20%, 25% and 30% for the same matrix (mortar). The compressive s...

    Abstract: The spectral responses are particularly important for the design of photodetectors operating in the wavelength range between 0,78μm to 2,6μm. To elaborate each device; we purpose a theoretical model to calculate the internal quantum efficiency. The theoretical curves of the internal quantum efficiency are obtained, by simulation to define the geome... Show More

    Abstract: In this work, effect of vanadium doping of CaCu3Ti4O12 (CCTO) on microstructure and complex dielectric constant over wide frequency (100 Hz-1 MHz) and temperature (0°C – 160°C) ranges has been studied. The vanadium doping of CCTO system results in an increase of grain size, the grains being surrounded by melted-like grain boundaries. Real parts of ... Show More
