The results of investigating properties of polytetrafluoroethylene (PTFE) and polyparaphenylene sulphide (PPS) films filled with dye molecules by co-deposition in vacuum are given. Thin polymer films filled with different polymethine dyes with various dye concentration are investigated. Film properties at room tempera…
ABSTRACT In this paper, a fuzzy based hybrid active power filter (FHAPF) is proposed for reducing harmonics and improving the power factor of a distribution system. The proposed filter consists of two control circuits such as Generalized PI control unit and fuzzy adjustor unit, in which, generalized PI control unit is…
The synthesis and characterization of Cu (II) complexes of three diuretic drugs acetazolamide, furosemide and hydrochlorothiazide are reported here. On the basis of elemental analyses, electrical conductivity and molecular weight data the adducts are assigned to the general composition [M(L)2]. All the adducts are par…
UO2 oxidation has been examined since the early age of nuclear energy civilian applications. Most studies refer to unirradiated analogues or low burnup spent nuclear fuels. Unirradiated UO2 or low burn up fuel follow the scheme UO2→U3O7→U3O8 having all oxides present during the process, while fuels with burnup > 35 GW…
Effect of Film Thickness on the Transmittance of Chemical Bath Fabricated CdS Thin Film was investigated in this paper. The films of different thicknesses were deposited on to glass substrate. Structural and surface morphology of the films were carried out using an x-ray diffractometer with Cukα radiation and Olympus…
This work highlights some of the issues regarding the application of the cohesive elements for modeling grain boundaries\nwith the purpose of capturing intergranular stress corrosion cracking in polycrystalline aggregates. The main\nissue relates to the computation of the normal stresses which at the triple lines betw…
Research and development (R&D) in nuclear safeguards, nonproliferation, and nuclear security is a cornerstone of the Joint Research Centre (JRC) Nuclear Safety and Security Work Program.\nThe main stakeholders are the Euratom safeguards authority and the International Atomic Energy Agency and close contact is maintain…
Engine EGR reforming was examined with a goal of improving the fuel consumption of engines burning ethanol-blended gasoline. The catalyst carriers of Rh catalyst were examined and optimized by using a flow reactor. The improved “carrier of ceria” is the most suitable. And engine EGR reforming was examined by an experi…
An experimental study of the post-impact spreading of liquid droplets on dry horizontal substrates is presented in this paper.The drop spreading and recoil behaviors are captured using a high-speed digital video camera at 2000 frames per second.To ascertain the effects of liquid interfacial and viscous properties, exp…
The biosynthesis of gold nanoparticles (GNPs) is demonstrated using Salmonella typhi cell exudates. The optimum parameters for the synthesis of nanoparticles were found to be inherent pH of the extract (7.35), high temperature (100oC) and 100 ppm aurochlorate. The results were verified by UV-Visible spectroscopy, High…
Citrate capped gold nanoseeds of uniform size and shape were prepared and used for CTAB-assisted growth of gold nanorods. Further, shape and size dependent hydrodynamic sedimentation behavior of nanostructure is exploited for separation of gold nanorods from mixture containing particles of different shape and size. Th…
In our work, the effect of crystallization methods and their parameters on the particle size, particle size-distribution and roundness were investigated in case of glycine crystallization. Three types of crystallization methods were applied according to the solubility results of the substance. In case of cooling cryst…
For the suppression of metallic particle lift-off in compact Gas-Insulated-Switchgear (GIS), a coating with nonlinear resistivity characteristic was adapted to the inner surface of GIS tank. Electrical field analysis using the measured current density to electric field (J-E) characteristics indicates that the nonlinea…
Friction Stir Welding is relatively young welding process in solid state which is created in The Welding Institute - London, during 1991 year. The first application is connected with railway and aluminum and aluminum alloys welding but later the application range is extended, so today this process successfully welded…
Crystals of potassium dihydrogen phosphate (KDP) doped with boron has been grown by slow solvent evaporation method at room temperature. The presence of boron is confirmed by EDAX. The presence of the functional groups has been identified by Fourier transform infrared spectrum. The grown crystal was characterized by p…
Titled homologous series consisting of eleven members is a liquid crystal in nature pentyl to decyl members of the series are liquid crystal (LC) while, rest of the members of the series are nonliquid crystals. Enantiotropic nematogenic mesophase with threaded or schlieren texture persisted for pentyl, hexyl, octyl an…
The phytochemcal screening and the effect of orally administered ethanolic leaf extract of Piliostigma thonningii on Serum lipid profile of male albino wistar rats were determined. Extracts of the leaf were first screened for presence of phytochemicals using chemical methods. Fifteen (15) albino wistar rats were rando…
The As-quenched hardness behaviour of 1.2% carbon steels in different quenching media was investigated. The hardness values were studied on two grades of high carbon steel materials, namely 1.2% carbon and low-alloy 1.2% carbon steels respectively. Specimens were prepared and given both spheroidizing and normalizing h…
This study investigated the capability of the grown Iron Oxide nanoparticles (NPs) for faster glucose detection. Horizontal Vapor Phase Crystal (HVPC) Growth Technique was utilized in the synthesis of Iron Oxide NPs from 99.99% purity Magnetite - Iron Oxide (Sigma- Aldrich) bulk material. Different parameters were var…
The inhibiting effect of leaf extracts of Hyppocratea pallens planhc.ex oliv on the corrosion of mild steel in 1.0 M HCl and 0.5 M H2SO4 solutions has been investigated by weight loss, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) techniques.
