Charge packets in insulating polymers-especially in polyethylene, have been reported by many groups in different laboratories within the last 15 years. They constitute an unexpected behavior in charge transport and understanding the mechanisms for their formation and propagation could participate in deepening our know…
Synthesis of RGO (reduced graphene oxide)-CdS composite material was performed through CBD (chemical bath deposition) method in which graphene oxide served as the support and Cadmium Sulfate Hydrate as the starting material. Graphene-based semiconductor photocatalysts have attracted extensive attention due to their us…
PURPOSE: To investigate the osteoconductive properties and biological performance of Poly L-lactic acid (PLLA) with omentum in bone defects. METHODS: PLLA nanofiber scaffolds were prepared via electrospinning technique. Forty four New Zealand white female rabbits randomly divided into three groups of 18 rabbits each.…
Electrospray-deposited poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) was investigated using several solvent solutions as a hole-transporting layer for spin-coated poly(3-hexylthiophene-2,5-diyl):[6,6]-phenyl-C61 butyric acid methyl ester (P3HT:PCBM) mixture organic thin-film solar cells (OSCs).…

Abstract Au@Pt core‐shell nanoparticles were successfully synthesized by a successive reduction method and then assembled on Vulcan XC‐72 carbon surface. Furthermore, its composition, morphology, structure, and activity towards methanol oxidation were characterized by UV‐vis spectrometry, transmission electron microsc…
High-voltage power metering systems based on electronic instrument transformers (EITs) have some advantages compared to the conventional ones. This paper describes an unique calibration method and device for the power metering system. High accuracy with the calibration method can be achieved. The estimated relative un…
In this study, an optical simulation of Cu(In,Ga)Se2 (CIGS) solar cells by the rigorous coupled-wave analysis (RCWA) method is carried out to investigate the effects of surface morphology on the light absorption and power conversion efficiencies. Various sub-wavelength grating (SWG) nanostructures of periodic ZnO:Al (…
Dye sensitized solar cells (DSSC) are photoelectrochemical solar cells. They are based upon an iodide tri-iodide redox couple mediated between a photosensitive electrodes of semiconductor materials stained with a photosensitive dye and a catalytic counter electrode. In the present investigation, ZnO compact layer was…
Our study on Sm1/2Ca1/2−xSrxMnO3 (x = 0, 1/6, 1/3, and 1/2) system shows an unusual consequence in magnetic field-induced transition to ferromagnetic metallic state and collapse of charge ordering in the intermediate compositions. Interestingly, the transition is sharp or step-like at low temperature that is observed…
LDPE is widely used as an insulating material for power cable. In order to clarify the conduction mechanism of LDPE under ac high field, the simultaneous observation of the dissipation current waveform and electroluminescence (EL) is carried out. As the results of experiments, it was found that when the EL was observe…
We describe work in which gold nanoparticles were formed in diamond-like carbon (DLC), thereby generating a Au-DLC nanocomposite. A high-quality, hydrogen-free DLC thin film was formed by filtered vacuum arc plasma deposition, into which gold nanoparticles were introduced using two different methods. The first method…
ZnMgO thin films deposited on Si (111) substrates by pulsed laser deposition at 300°C were annealed at different temperatures from 400 to 800°C in air. Non-polar films with (110) orientation have been obtained. The thin film annealed at 500°C shows the co-existence of (002), (200) and (110) orientations according to X…
Based on density functional theory, the mechanisms for oxygen-driven unzipping of carbon nanotubes under electric field are presented. Under the control of external electric field, O adatoms will diffuse along the single-walled carbon nanotube from low potential to the high potential sites. The energy barrier of O ada…
In this paper, we report the enhanced performance of Graphene-Nafion-GOD based enzymatic biosensors to detection glucose used fast, simple, and easy to control fabrication method. These materials are prepared by mixing graphene, a Nafion perfluorinated resin, and glucose oxidase (GOD) in appropriate amounts. The graph…
Continued demands for better control of the operating conditions used in human motion tracking and medical applications have led to the need for better means of detecting different types of proprioceptive activity pattern. One way to satisfy this need is to use MEMS technology to develop a sensor which can be used lat…
Abstract To describe the rich phenomena in dilute dispersions of highly charged colloidal particles, it is necessary to modify the long-range electric part of the DLVO potential. The screened Coulombic potential of pure repulsion obtained from the Helmholtz free energy in the DLVO theory is replaced by a new screened…
A novel DC through hole filling process was formulated for high volume HDI and substrate core layer metallization production. The process yields high quality results over a wide current density range.
This paper reports the synthesis and self-assembling properties of 6-O-hexadecyl- and 6-O-octylsucroses. Mono-etherification of 2,3,4,1′,3′,4′-hexa-O-benzylsucrose with the corresponding alkyl bromides predominantly took place at the glucose 6-position and the products were isolated by silica gel column chromatography…
