Ti‐6Al‐4V alloy is a workhorse of titanium industry; it accounts for about 60 percent of the total titanium alloy production. The high cost of titanium makes net shape manufacturing routes very attractive. Casting is a near net shape manufacturing route that offers significant cost advantages over forgings or complica…
The static and dynamic properties of a system of end-grafted flexible ring polymer chains grafted to a flat substrate and exposed to a good solvent are studied by using a molecular dynamics method. The monomers are described by a coarse-grained bead-spring model. Varying the grafting density ρ and the degree of polyme…
Asian Journal of Chemistry, a Multidisciplinary Chemistry Journal is an Peer Reviewed International Journal and publishes from India. The journal has been established since January 1989 on a firm foundation of International Quality Research. This Journal encompasses all branches of chemistry and its sub – disciplines…
Biosurfactant was obtained from Nocardiopsis VITSISB and it was used in cosmetic formulation of toothpaste, replacing Sodium Lauryl Sulphate which is normally used in commercial toothpaste as a surfactant. This biosurfactant toothpaste was qualitatively analyzed by several tests like Spreadability Test, Foaming abilit…
Synthesis of silver nanoparticles is achieved through methods such as physical, chemical and biological. Biological method of nanoparticles synthesis is economical and eco-friendly. The plant extract of DaturaalbaNees. incubated with silver nitrate showed gradual change in colour from colourless to reddish brown with…
The first criterion for the electrolyte of solid oxide fuel cells (SOFC) is to have sufficient ionic conductivity without any significant electronic conductivity. Since the cell operates at high temperature, it must withstand that operating temperature along with stability in both reducing and oxidizing environments.…
Rubbers in general are seldom used in their pristine form. They are too weak to fulfill practical requirements because of lack of hardness, strength properties and wear resistance. So they are used with a number of other components called fillers which improve the processability, performance properties and life of the…
Nanotechnology involves the creation and manipulation of materials at nanoscale levels (1-100 nm) to create products that exhibit novel properties. While this motivation has driven nanoscience and technology in physics and engineering, it is not the main reason that nanoparticles are useful for systemic applications i…
Hydration and hardening properties of magnesium potassium phosphate cement paste(MKPC) containing composite retarders(CR) were investigated by testing and analyzing its setting time,hydration heat,compressive strength,phase component and microstructure,which were compared with those of MKPC paste with borax(NB) added.…

BaSO 4 :(Mn 6+ , Mn 5+ ) crystal was grown using MnCO 3 as manganese source at high temperature from 650 to 750°C by the NaCl-KCl flux method in air and its spectroscopic properties were investigated. The experimental results indicate that Mn 6+ and Mn 5+ ions coexisted in the crystal. A broadband emission band peakin…
Carbon nanotubes (CNTs) have found many potential applications stemming from their small dimensions and marvellous electronic, mechanical, and thermal properties. One of the barriers for using CNTs as building blocks in nanoelectronics is the high contact resistance. This paper reviews recent progress on the research…
Two hundred and four strains of biocellulose (BC)-producing Gluconacetobacter strains were isolated from 48 rotten tropical fruits collected in Thailand. Twenty-nine representative isolates were selected from each of the 16 isolation sources and identified by morphological, physiological and biochemical characteristic…
The present theories and experimental methods to evaluate the swelling behaviors by gravimetric measurement were experimentally tested for polyvinyl alcohol (PVA) films. It was found that the swelling behaviors and swelling kinetic parameters, such as diffusion exponent n, by gravimetric measurement may be greatly inf…

Drug delivery to the brain is always a challenging task for the formulation scientists because of low permeation due to presence of blood brain barrier (BBB) with tight junctions in the brain endothelial cells. Even though numerous traditional approaches such as prodrugs, disruption of blood brain barrier have shown s…
In this paper, we report on the impact of the structure of ligands on the luminescence enhancement of Eu(III) by directly exciting Eu(III) with visible light in aqueous media. Upon replacing the water molecules that coordinated around a Eu(3+) ion with a ditopic ligand 1,11-bis(2,6-dicarboxypyridin-4-yloxy)-3,6,9-trio…
Grinding of solid brivaracetam (BRV) and seletracetam (SEL) with inorganic lithium salts yields original ionic co-crystals (ICCs) characterized by markedly different thermal properties with respect to pure racetams; solid products have been characterized by single crystal crystallography. It is suggested that co-cryst…
The binding properties of the two ligands (L) N,N'-bis[(3-hydroxy-4-pyron-2-yl)methyl]-N,N'-dimethylethylendiamine (Malten) and 4,10-bis[(3-hydroxy-4-pyron-2-yl)methyl]-1,7-dimethyl-1,4,7,10-tetraazacyclododecane (Maltonis) towards M(II) transition metal ions (M(II) = Cu(II) for Malten and Co(II) for Maltonis, respect…
Silver/carbon (Ag/C) core–shell nanowires with different thickness of shell were synthesized by a hydrothermal method and used as templates for fabricating gold nanoparticle-decorated Ag/C (Ag/C/AuNPs) nanowires. The Ag/C/AuNPs nanowires were characterized by transmission electron microscopy (TEM), high-resolution tra…
