In order to study the microstructure and mechanical properties of Copper Beryllium alloy, spreadability test was carried out at two temperatures under Argon atmosphere for different filler metals of Ag content. The results show that BAg2a (Ag–26Cu–21Zn–19Cd) and BAg1a (Ag–18.5 Cu–17Zn–14.5 Cd) are the best choice for brazing of Copper Beryllium. Zn affects the wetting of interlayer because it spreads preferentially. The bonding process was carried out at a temperature ranging of 650–800 C for various times under ...

Quantum-confined semiconductor structures are the cornerstone of modern-day electronics. Spatial confinement in these structures leads to formation of discrete low-dimensional subbands. At room temperature, carriers transfer among different states due to efficient scattering with phonons, charged impurities, surface roughness and other electrons, so transport is scattering-limited (diffusive) and well described by the Boltzmann transport equation. In this review, we present

The electrical behavior of Silicon On Insulator (SOI) devices has been investigated with the help of computer simulations. As, the technology has been aggressively reduced in size over the last few decades, the SOI device effectively suppresses the short channel effect (SCE) and other parasitic effects in comparison with conventional bulk devices. At the same time more physics based modeling is used to investigate device's electrical behavior. The quantum effect has been computed by using density gradient method along with hydrodynamics model for transportation of charge carriers in Fully Depleted (FD) and FinFET SOI devices. In this paper we investigate the sensitivity of impact ionization in SOI devices by varying its internal temperature at constant doping concentration of 1×17 cm−3. The threshold voltage becomes sensitive and varies for high operating temperature for both accumulation and inversion modes. FD SOI device shows better control of threshold voltage as compared with FinFET SOI device in inversion mode. But in accumulation mode FinFET SOI devices shows better response on threshold voltage than FD SOI device. Impaction ionization for both FD SOI device and FinFET SOI device reduces with increasing temperature.

The unison of nanotechnology and polymer science enables the development of novel silver-based polyester nanocomposite as an antimicrobial coating material. Highly branched polyester/clay silver nanocomposites based on vegetable oil with different loadings of silver were prepared via reduction of silver salt by employing dimethylformamide as solvent as well as reducing agent at room temperature. Organically modified montmorillonite clay of 2.5wt%

In recent years, we noticed that soft set theory have many applications in many real-life problems in different fields such as the field of " engineering, social sciences, medical sciences " etc. It is clear that the notion of soft topological space and its concepts (such as soft near open sets) has been developed with the help of soft sets in many applications. In the present paper, we introduce new class of soft near open sets called " soft simply open sets " and " soft delta sets " as a generalization and modification for soft open sets (resp. some of soft near open sets). We further investigate some relationships among various soft open sets and finally we study some of their properties.
