Aging diagnosis of silicone rubber composite insulator based on conduction current test
This paper presents a new criterion on aging diagnosis of silicone rubber composite insulator. Taking being operated composite insulators as the object, the electrical degradation threshold was obtained by the conduction current test, then the hydrophobic of samples was obtained by static contact angle measurement and…
Characterization of the internal parameters of nanostructured light induced thermionic emission devices for energy conversion
We propose a method to calculate the output current-voltage characteristics of a light induced thermionic emission device. This approach improves on the existing methods by having both a higher precision and higher range in evaluating the associated integrals, resulting in simulated device characteristics with a wider…

In this study, an investigation on mechanical properties of flax natural fiber composite is performed as a precedent study on the design of eco-friendly structure using flax natural fiber composite.The Vacuum Assisted Resin Transfer Molding-Light (VARTML) manufacturing method is adopted for manufacturing the flax fibe…
The series calculation model for the magnetic field of coil above arbitrary layer conductive plates
In calculation the magnetic field of the coil above multilayer conductive plates, time consuming and implementation difficulties are the main problems. A series expansion method was proposed to calculate the magnetic field, based on the Maxwell equations, the magnetic vector potential and solution region truncation. T…

SINTERING AND CHARACTERIZATION OF WC-20WT.% (FE, CO) NANO-STRUCTURED POWDERS DEVELOPED BY BALL-MILLING
WC-based cemented carbides Ball milling Microstructure Hardness Sintering The aim of the present work is to study the effects of the nanostructured WC-20 wt. % (Fe,Co) with different iron to cobalt ratios on microstructure and hardness of the sintered samples. Furthermore, a sample with a cobalt binder was produced un…
Fluorescence Spectroscopy Of Lysozyme-Silver Nanoparticles Complex
Identifying the nature of protein-nanoparticle interactions and favored binding sites is an important issue in functional characterization of biomolecules and their physiological responses. Herein, interaction of silver nanoparticles with lysozyme as a model protein has been monitored via fluorescence spectroscopy. Fo…
Metallic Sn- and SnO2-doped SAPO-34 as Model Catalysts for Investigating the Effect of Oxidation States on Bio- Ethanol Dehydration Products
Over the last decade, due to the increase of energy demand and lower cost of bio-ethanol production, the conversion of bio-ethanol to valuable products such as light olefins, paraffins and aromatics have been received considerable attention. From the previous result, it was found that tin oxide doped on SAPO-34 was di…
Electrochemical biochip for applications to wireless and batteryless monitoring of free-moving mice
A multi-sensing platform for applications in wireless and batteryless monitoring of free-moving small animals is presented in this paper. The proposed platform hosts six sensors: four biosensors for sensing of both disease biomarkers and therapeutic compounds, and two further sensors (T and pH) for biosensor calibrati…
Microstructure and wear resistance of spray formed and conventionally cast high‐chromium white iron
A billet of hypoeutectic high‐chromium white iron (19% Cr, 2.5% C) was spray formed using Gas‐to‐Metal Ratios (GMR) of 0.9, 1.0, and 1.1. Microstructural studies and dry sand rubber wheel abrasion tests were carried out, on the one hand, to compare between the spray formed and conventionally cast material and, on the…
Phase Transformation in Ultra-Thin Films
Thickness dependent structural phase transformation in thin polycrystalline metal films has been reviewed. Various effects of film thickness reduction on film microstructure have been identified. Film thickness dependent structural phase transformation has been treated thermodynamically taking polycrystalline titanium…

Losses in VSI-PWM fed axial flux machines
The goal of this paper is to study the additional loss caused by Pulse Width Modulation (PWM), on the one hand in an axial flux permanent magnet synchronous machine (PMSM), and on the other hand in the voltage source inverter (VSI) that supplies the machine. Via a computationally efficient technique, the losses are co…
Effect of the grain boundary on the dielectric breakdown strength of (Ba0.4Sr0.6)TiO3 paraelectric ceramics with various grain sizes
(Ba0.4Sr0.6)TiO3(BST) paraelectric ceramics (Tc≈ -67 °C) with various grain sizes (0.6-1.8 μm) were synthesized by oxalate co-precipitation method and prepared by conventional solid-state sintering process. With decreasing grain sizes, the dielectric breakdown strength increases gradually. Based on the conductivity ac…
