Non-Volatile Memory (NVM) technologies are promising alternatives to traditional CMOS memory technologies. While NVMs were primarily studied to be used in the memory hierarchy, they can also provide benefits in reconfigurable systems such as Field-Programmable Gate Arrays (FPGAs). In this paper, we investigate the app…
The polymer solar cell is a promising candidate for the next-generation solar cell because of its light weight, flexibility and easy fabrication. In this manuscript, we report on polymer solar cells based on P3HT: []-phenyl-C61-butyric acid methyl ester with 1:1 weight ratio blending as active layer. To improve the pe…
Interaction of trichloroethene with sodium tetra- and pentasulfide (prepared in turn from sodium sulfide and elemental sulfur) has lead to new family of polyvinylenepolysulfides containing up to 94% of sulfur. The polymers were found highly electrochemically active when applied as active cathode for lithium batteries.
The change of intensities of optical transitions of atoms, molecules, and their ions in the near field of nanoobjects is of interest for researchers from both basic and applied points of view. The concept of a near field was used as early as the 1960s to study the mechanisms of hypersensitive transitions of rare-earth…
Density functional theory is used to investigate sulfur dioxide physisorption inside and outside of single-walled carbon nanotube (SWCNT) of (5,0) and (5,5). This study is conducted at B3LYP/6-31G* level of theory. Sulfur dioxide molecule is studied with axis oriented parallel or perpendicular to the nanotube wall. Bo…
Nigeria and other nations are looking for solution to their energy crisis and nuclear energy seem to be an option as Federal Government have mandated NAEC, an apex arm of government charge with development of nuclear energy programme for the country to look at the possibility of using nuclear power to generate electri…

The model of a class of irreversible solid oxide fuel cell (SOFC) and the semiconductor thermoelectric generator (TEG) hybrid power system is established. The general expressions of several important performance parameters of the system such as the power output, efficiency, and minimum electric current density of the…
The magnetism and work function Φ of Fe 1— x Gd x /Fe (001) films have been investigated using first-principles methods based on the density functional theory. The calculated results reveal that Gd doping on the Fe (001) surface would greatly affect the geometrical structure of the system. The restruction of the surfa…
In this work, a series of hydrogel nanocomposites were prepared by grafting acrylic acid and acrylamide on gelatin in the presence of Na-montmorillonite (Na-MMT) nanoparticles. The characterizations of hydrogel nanocomposites were examined by swelling experiments, Fourier transform infrared (FT-IR) spectroscopy, X-Ray…
Direct Bonded Copper (DBC) is now commonly applied as heat transfer substrates for high power electronics. The metallizaed surfaces are designed for improving the heat conduction and joining with copper heat sink. However, due to the mismatch of coefficient of thermal expansion, the joining area is usually the failure…
The aim of this paper is to develop a kind of copper matrix self-lubricious material with excellent friction and wear characteristics. The copper-graphite composites reinforced with short copper-coated carbon fibers (CF-C/Cu) were successfully developed using techniques of mechanical alloying, composite plating and ho…
A facile, efficient, and low energy consumption detonation method to prepare few-layered graphene nanosheets has been developed using graphite oxide as a precursor at detonation induced temperature as low as 100 °C . The composition and structure of as-produced few-layered graphenes were characterized by X-Ray Diffrac…
In order to determine the best curing conditions of silicate wood adhesive, three different curing conditions, i.e. room temperature, moderate temperature, and high temperature were chosen to prepare poplar plywood with silicate adhesive and poplar veneer as raw materials. The optimised curing technology was obtained…
Papermaking industry generates a considerable amount of wastewater including varieties of pollutants. This paper reviews the ordinary processes of treating papermaking wastewater, and introduces the merits and demerits of these processes. The latest technologies are summed up. A forecast is made through all the method…
Insulation is an important part in an electric power system. There are many materials used as insulation in electric power equipment. Epoxy resin is a kind of polymeric insulation which is used as indoor as well as outdoor insulators. Under operating condition and polluted environment a large leakage current (LC) may…
The optimization of processing conditions and material chemistries has enabled the uniform integration of PEDOT:PSS within a polyurethane matrix to fabricate elastomeric fibers with high electrical conductivity, using a simple fibre wetspinning process. J. M. Razal, G. G. Wallace, and co-workers report the fabrication…
A wavelength swapping nondegenerate pump-probe technique to measure the magnitudes of the nonlinear optical dynamics as well as the relaxation time of electrons in high energy levels is presented using a ZnS single crystal wafer as an example. By pumping the sample with 800 nm femtosecond pulses and probing at 400 nm,…
In this paper the effect of various rotor core material for high speed Solid Rotor Induction Motor (SRIM) have been analyzed. A comparative study, regarding the performance of high speed SRIM on variation of various material properties has been made. It has been observed that a material with good electrical conductivi…
A consistent thermodynamic description of the process of stationary eutectic solidification at low supercoolings is presented. To find the relation between the parameters that characterize this process, a new approach has been used that is based on obtaining an expression for the rate of the free-energy change by two…
