Vinylation reaction was investigated by catalytic system in the presence of aromatic acetylene alcohols (AAA) with acetylene. Theoretically proposed factors affecting the process of the reaction. The influence of the nature and amount of catalyst, the molar ratio of the starting materials during the reaction temperatu…
Large single crystal domains of WS2 are grown by chemical vapour deposition and their photoluminescent properties under lateral electric field are studied. We demonstrate that monolayer and bilayer WS2 have opposite responses to lateral electric fields, with lateral electric fields causing monolayer WS2 photoluminesce…
Cavitations phenomenon is resulted from elevated temperature and pressure and production of free radicals. This technology can be employed to disinfect drinking water and waste water. What is important in cavitations reactors is the production of hydroxyl radicals, which plays a significant role in removing coliforms.…
There is great interest in developing eco-friendly green biocomposites from cropderived bioplastics attributable to their renewable resource-based origin and biodegradable nature. Fully nonbiodegradable and nonrenewable nature of plastic packaging has led to a renewed interest in packaging materials based on eco-frien…
Bulk metallic glass Cu 29 Zr 32 Ti 15 Al 5 Ni 19 was successfully prepared in a copper mold with designing idea of high entropy alloys. The compressive strength of glassy Cu 29 Zr 32 Ti 15 Al 5 Ni 19 is 1673.4MPa. Particular attention should be pay to that it shows a plastic deformation high up to 20% during compressi…
The power quality problems like voltage sag, voltage swell, harmonics etc can be compensated through a three phase four wire unified power quality conditioner (UPQC) under unbalanced and distorted load condition. UPQC is a device which is used to share the active power between shunt and series converters through DC li…
Large capacity content addressable memory (CAM) is a key element in wide variety of applications. A major challenge in realization of such systems is the complexities of scaling MOS transistors. Converges of different technologies, which are well-matched with CMOS processing may allow extension of Moore's law for a ne…
Silicon carbide is currently used as a structural material for heat exchanger tubes and related applications because of its excellent thermal properties and oxidation resistance. Silicon carbide suffers corrosion degradation, however, in the aggressive furnace environments of industrial processes for aluminum remeltin…
This study developed a rapid, eco-friendly and convenient green method for the biosynthesize of stable silver nanoparticles have been prepared by hot chemical reduction method with using agar as a biopolymer matrix and a capping (reduction) agent to get a Ag - agar hybrid NP (hybrid core / shall NP). We prepared the s…
a b s t r a c t Flax (Linum usitatissimum L.) is a potential winter crop for the Southeast USA that can be grown for both seed and fiber. The objective of this research was to evaluate the effect of irrigation on flax straw, fiber, and seed yield of fiber-type and seed-type cultivars at different flax growth stages. T…
Using the perturbation method based on a variational phonon basis obtained by the modified Lang-Firsov (MLF) transformation, the two-site double-exchange Holstein model is studied in presence of a finite difference in bare site energies (ǫd=ǫ2-ǫ1). The polaronic ground-state wave function is calculated up to the fifth…
The evaluation of essential oil (Aloe-vera) on the Bomyx mori has been proved to be in Sericulture industry. This study was carried out to show the influence of Aloe-vera oil on the number of fertilized eggs (%) and incubation period of Bombyx mori eggs. In 0.25, 0.5 and 0.75 ml. amount of Aloe-vera oil, the incubatio…
Ritonavir, a widely prescribed anti retroviral drug belongs to class II under BCS and exhibit low and variable oral bioavailability due to its poor aqueous solubility. Its oral absorption is dissolution rate limited and it requires enhancement in the solubility and dissolution rate for increasing its oral bioavailabil…
Accepted on 21 February 2015 _____________________________________________________________________________ ABSTRACT Several 1-Hepta-O-benzoyl-β-D-lactosyl-3-alkyl carbamates have been synthesized by the interaction of Hepta-O-benzoyl-β-D-lactosyl isocyanate with various alcohols. The identities of these newly synthesi…
The important influence of thermodynamic effect inside bubble and viscous liquid volume outside the bubble on the dynamics of bubble can be found. However, the combined effect of those two factors has currently little research and the thermodynamic effect of the bubble can be seen from the Flynn model. Taking thermody…

In this work, temperature dependent electrical and thermal conduction in the bio-supported 3.2 nm-thin Ir nanofilm and individual silver nanowire are studied at reduced temperatures. For the Ir film, by studying the temperature-dependent behavior (300 K down to 43 K) of electron thermal conductivity (), we quantify t…
The wetting and spreading of molten filler materials (pure Al, pure Ag, and AgAl alloys) on a Kovar™ (001) substrate was studied with molecular dynamics simulations. A suite of different simulations was used to understand the effects on spreading rates due to alloying as well as reactions with the substrate. The impor…
Graphene is a 2D flat-mat consisting of a honeycomb-like structure of carbon atoms with sp 2 bonding character for each carbon. It exhibits excellent electrical conductivity and mechanical strength, and can be synthesized in a number of ways. Most syntheses involve first oxidizing graphite to Graphene Oxide (GO), Func…
The main objective of this work is to find alternative materials for the cutting tools used in turning operations. The conventional materials like tungsten carbide(WC), titanium carbide(TiC), cubic boron nitride (CBN) and diamond used as cutting tools for turning operations on lathe are expensive. Titanium grade 5 (Ti…
