Density functional theory (DFT)-based calculations are performed to determine the effects of preadsorbed atomic hydrogen (H) and substrate reconstruction on the absorption of H into bilayer graphene via the armchair edge. The total energy is calculated using the Vienna Ab-initio Simulation Package (VASP) software for…
Titanium dioxide thin films have been deposited onto glass substrate by spray pyrolysis technique at different substrate temperature(Ts =300 0 C to 400 0 C) and annealed at 500 0 C for 1hr.The annealed films were characterised by x-ray diffraction,scanning electron microscopy and uv-vis spectroscopy in order to identi…
This need to assure higher reliability has resulted in a growing industry trend to de-gas and remove from service, de-gas and repack or replace valves to improve emission performance. This operating strategy requires improvements in valve repair practices to assure each valve completes its expected life cycle between…
One of the radiotherapy has boron neutron capture therapy (BNCT). They may make it easier to kill tumor cells with BNCT. In BNCT, it is important for boron agents, which have high selectively and high accumulation, to be introduced into tumor cells. To date, the main boron compounds used by the clinical study are sodi…
This paper discusses the effect of a metal chloride pre-cursor on the phase formation of Yb-doped Ba(Ce, Zr)O 3 solid electrolyte derived from a sol-gel method via acetate and chloride salts. The use of metal chloride as a pre-cursor showed the increased in thermal decomposition temperature (T td ≈1360 o C) compared t…
strongly with the presence of these structural features than with size. We further suggest that the presence of dangling-O atoms on TiO2 clusters or surfaces may be associated with enhanced catalytic activity and that these O atoms may serve as active sites. The process of optimization for a target property reveals th…
The objective of this study is to isolate indigenous cellulose-degrading bacteria from soil samples collected in Taiwan. After isolation by culture enrichment followed by strain acclimation, the characteristics of these bacteria were investigated. Three distinct soil samples were collected; those were hot spring drain…
Nigeria is blessed with abundant solid mineral deposits scattered in different parts of the country. As a measure to curtail the total dependence of imported commercial adsorbent for the treatment of our petroleum wastewater, Kankara kaolin from Katsina state, Nigeria was pretreated and blended with a commercial zeoli…
Polymer nano particle composite membrane has drastically increases the efficiency in purification process. In view of its practical applicability it leaves a platform for the researcher to synthesize ,characterize and study of pore size of 0Dnonmaterial composite membrane. Metal nanoparticles of different size are int…
We report a process for preparing poly(butylene terephthalate) (PBT) powders of diameter smaller than 100 m in quantitative yield using amphiphilic block copolymer phase inversion process. 1 Poly(benzyl acrylate)-based block copolymers of controlled M composition were prepared by RAFT polymerization for making PBT po…
The aim of this research was to determined phytoplankton variety and quality of Binuang Dam chemical-physics waters. Methodology this research is descriptive and observation is arranged to direct observation at the site, water and phytoplankton sampling was done on 4 different observing stations. The observation was r…
Abstract: A representative of the fluoride-containing iron pnictide high-temperature superconductors, namely CaFFeAs, was doped with sodium up to the composition Ca 0.86 Na 0.14 FFeAs for the first time. Single crystals with an edge length in the range of 0.1 – 2.0 mm were obtained via solid-state and flux syntheses,…
The paper presents the effect of plastic strain occurring at room temperature in annealed samples of AISI 304L austenitic chromium-nickel steel on content of strain-induced α′ martensite in its structure. The strain was introduced by uniaxial tension with constant strain rate of about 0.083 mm/s. It has been demonstra…
Fixed-dose combination chemotherapy holds great potential for management of cancer. Thus a drug delivery system which can administer a controlled ratio of several drugs simultaneously and control the drug release at the cancer site is highly desired. In this work, a fixed-dose dual drug loaded polymer micelle is forme…
Macro shrinkage results, due to the interaction of several complex influences in iron. The grating, risering, and the iron chemistry needs to revised, when the shrinkage is constantly present in cast products on a regular basis. It has been observed that the problem of macro shrinkage is within the control and timing…
Now a days the global warming and air pollution are big issues in the world. The 70% of air pollution is due to emissions from an internal combustion engine. The harmful gases like NOX, CO, unburned HC and particulate matter increases the global warming, so catalytic converter plays an vital role in reducing harmful g…
The results of an X-ray diffraction experiment performed on the Aleppian Belon have shown that the natural and the processed Belon with solvents LiCl, KCl and NaCl are composed of Ankerite, Leucite, Halloysite, Quartz and CO2AL2O5.8H2O. The proportion of these found components varies depending on the quality of the so…
Metal (Ag and Mg) doped ZnO thin film was prepared by sol-gel spin coating method on glass substrates followed by annealing at 4 different temperatures (300 to 450°C) to understand the structural behavior. The structural analysis of Mg doped ZnO thin film was showed the crystal grown in their preferred hexagonal (100)…
Abstract: The density and the viscosity measurements of polymer blend solutions form an important tool for the evaluation of parameters which give an insight into the nature of miscibility and molecular interactions in polymer blend. Inthe present investigation, densities and viscosities have been measured in 4 % solu…
Solubility is one of the important parameter to achieve desired concentration of drug in systemic circulation for pharmacological response to be shown. Poorly water soluble drugs often require high doses in order to reach therapeutic plasma concentrations after oral administration. Low aqueous solubility is the major…
