The effects of initial temperature and cooling rate on the freezing behaviors of clusters Co531, Cu531, and Ni531 are studied by the molecular dynamics with a general embedded atom method. The results show that their freezing points are obviously influenced by initial temperature and cooling rate. Higher initial tempe…
Light induced degradation caused by boron-oxygen complexes in compensated Czochralski-wafers produced from 50% Elkem Solar Silicon® (ESSTM) and 50% non-compensated polysilicon is studied. Minority carrier lifetimes are measured using QssPC calibrated photoluminescence imaging and illumination with 1 Sun is used to ind…
The objective of the study was to formulate micro particles of a poorly soluble drug Ketoprofen with the aid of Chitosan in presence of salting out agents. Dissolution Studies were carried out in 0.1N HCl using USP type II dissolution apparatus. The effect of Chitosan in presence of salting out agent predominated drug…
The purpose of controlling the quenching process of an orange-hot steel workpiece is to ensure its required surface hardness. A sound in a cooling liquid generated by the quenching process was experimentally analyzed. It contains sufficient information about the ongoing process for its quantification, and it can be us…
Maximizing filler loading in order to improve papermaking economics and optimize paper quality is of continuous interest to the producer of printing and writing papers. Traditionally filler is primarily applied to the sheet in the wet end as so-called internal loading. In the surface filling process one or two percent…
This paper investigates the excited states of Si 3 O molecule by using the single-excitation configuration interaction and density functional theory. It finds that the visible light absorption spectrum of Si 3 O molecule comprises the yellow and the purple light without external electric field, however all the visible…
The ethanolic extract of the roots of Hemidesmus indicus was investigated for its nephroprotective activity in Cisplatin induced renal injury in rats. In the curative regimen, the ethanolic extract at dose levels of 250 and 500 mg/kg showed dose-dependent reduction in the elevated blood urea and serum creatinine. Ther…
This paper aims to investigate the dynamic mechanical properties of Polycarbonate material processed by Fused Deposition Modeling (FDM) rapid prototyping process. Frequency sweep is performed in Dynamic Mechanical Analysis (DMA) 2980 equipment to get modulus, damping and viscosity values. The effects of FDM parameters…
The reflection property of alkaline textured wafers is an important parameter for texture evaluation. Nevertheless, the geometric properties of the surface structure influence cell performance and cannot be distinguished by reflection measurements only. The pyramid size distribution can affect, e.g. contact formation…
In this paper some polyurethane membranes were prepare by electrospraying process to obtain biocompatible materials. The polyurethanes utilized in this study were synthesized from hexamethylene diisocyanate (HDI), polytetramethylene ether glycol (PTMEG) and butanediol (BD) filled with different proportion of hydroxypr…
Microcrystalline Cellulose (MCC) is a very important product in pharmaceutics, foods, cosmetics and other industries. In this study, Beeswing (-20L) and Chaff. (+5) which are the parts of corn cobs were used as raw material to produce MCC via alkaline degradation. The effects of concentration of sodium hydroxide solut…
Zinc Aluminum Oxide (ZAO) thin films were prepared by DC reactive magnetron sputtering on glass substrates and the effect of substrate temperature (from 303K-623K) on the structural and optical properties were studied. XRD patterns of ZAO thin films deposited at different substrate temperatures exhibit (0 0 2) prefere…
The brain is a fragile organ as well as complicated. The brain is protected from many toxic substances and various chemicals by the presence of two barriers namely blood brain barrier (BBB) and blood cerebrospinal fluid barrier (BCSFB). BBB it protects the brain because of restrictive angio architecture with endotheli…
Summary The plant Kigelia africana (Lam.) Benth. is used in traditional medical practices of Africa and India to treat hepatic diseases. The present study is designed to evaluate the effect of K. africana fruit extract (KAFE) on lipid profiles in Triton X-100 induced hyperlipidemia in male wistar rats. The aqueous and…
Nanotechnology is a multidisciplinary field and has achieved breakthroughs in bioengineering, molecular biology, diagnostics, and therapeutics. Targeted delivery of therapeutic agents has the potential to localize drugs to a specific tissue as a mechanism to enhance treatment efficacy and abrogate side effects. The su…
New metal complexes of the ligand 2 -thioaceticacid-5-Pyridyl-1,3,4-oxadiazole ( HL) with the metal ions Ni (II) Cu(II) Co (II) and Fe ( III) were prepared in al coholic medium, the prepared complexes were characterized by FTIR spectroscopy, electronic spectroscopy, elemental analysis, magnetic susceptibility, conduct…
Measuring the secondary electron yield (SEY) on technical surfaces in accelerator vacuum systems provides essential information for the study of electron cloud growth and suppression, with application to many accelerator R&D projects. As a part of the CesrTA research program, we developed and deployed an in-situ SEY m…
Aim: To clone the gene of Xylose isomerase (XyI) from thermophilic Geobacillus caldoxylosilyticus TK4 strain and to express and characterize this enzyme. Methods: XyI gene of Geobacillus caldoxylolyticus was cloned into pET28a(+) vector and expressed in Escherichia coli. The recombinant protein was purified by using n…
Open-cellular elastomeric nanocomposite foams were obtained by polymerization of water-in-oil high internal phase emulsions (HIPEs) containing 2ethylhexylacrylate, styrene, divinylbenzene, and organo-modified montmorillonite (org-MMT)s. The effects of various org-MMT contents on the emulsion viscosity and microcellula…
