Following an experimental discovery of its extremely high thermal conductivity, graphene was proposed as material for heat removal. To evaluate the feasibility of graphene's use for thermal management we simulated heat propagation in siliconon- insulator (SOI) structures with and without graphene or few-layer graphene…
. Aqueous suspensions containing small magnetic particles have been increasingly used in biosciences and biotechnology. Magnetic particles develop magnetic polarization and magnetophoretic mobility, and because of such unique properties, these carriers may be eligible candidates for delivering drugs to specific sites…
Polyaniline (PANI) nanocomposites were synthesized by incorporating separately synthesized metal nanoparticles in 1-methyl-2-pyrrolidinone (NMP) solution of polyaniline. PANI was prepared by oxidative reduction of aniline using chemical method. Silver nanoparticles were produced by inert gas condensation; whereas gold…
The pentagon-heptagon (5/7) pair in a zigzag single-walled carbon nanotube (SWCNT) is described as a dislocation by the modified Peierls-Nabarro (P-N) theory. The theory takes discrete effects, size effects and curvature effects into account. The bonds variation and shape distortion caused by 5/7 pair have been evalua…
Molecular dynamics simulations in three-dimensional single crystal copper under remote uniaxial tension at high strain rate (10 9 /s) were performed to analyze the microscopic mechanism of dislocation emission and void interaction. Two different cases, characterized by whether the line joining centers of two embedded…

Salicylic acid-Formaldehyde-m-Cresol (SFM) terpolymer had been synthesized in DMF media by conventional method. The resulting resin had been characterized by FTIR spectra, elemental and thermogravimetric analyses. The morphology of SFM resin had been studied by SEM and Optical photograph. Various parameters like rate…
This paper presents two technical frameworks that can be used to effectively monitor both ethylene propylene diene monomer (EPDM) and silicone rubber (SiR) composite insulators during their life in service, and provide a tool that assists asset managers decision making. The first framework, derived from a more general…
Chemical vapor deposited (CVD) Ruthenium liners and DirectSeedTM(DS) copper were used with advanced Electrofill processes to provide lower resistance wiring compared to results using CVD Ru and conventional physical vapor deposited (PVD) Cu seed for back end of line (BEOL) structures. Different annealing temperatures…
Nanocrystalline Gd1.1Lu0.8Eu0.1O3powders were prepared by a combustion method with different fuels such as glycine, citric acid, and urea. The as-prepared particles are of nanoscale size, near-spherical shape, and weak agglomeration. The solid solution transparent ceramics of Gd1.1Lu0.8Eu0.1O3were prepared using the p…
This paper describes the result of measurement of normal flux distribution 3-phase 100kVA transformer core assembled with the mix 60° - 23° in different layers of T-joint. The investigation involves the variation of normal flux distribution in the core lamination. The normal flux distribution has been measured using n…
In the article method of analysis of parameters of disk radiators of step-variable form according to requirements of technological process and geometric sizes of the disk is described.
Abstract Fluoroleakeite, NaNa 2 (Mg 2 Fe 3+ 2 Li)Si 8 O 22 F 2 is a new mineral of the amphibole group from the Verkhnee Espe deposit, Akjailyautas mountains, eastern Kazakhstan district, Kazakhstan. The granites and their host rocks have been intensely reworked by post-magmatic and host-rock fluids, resulting in inte…
Microstructure evolution of the homogenised ZK40 magnesium alloy was investigated during compression in the temperature range of 250–400°C and at the strain rate range of 0·01–50 s −1 . At a higher strain rate (⩾10 s −1 ), dynamic recrystallisation developed extensively at grain boundaries and twins, resulting in a mo…
Dissimilar metal combinations are often necessary when manufacturing a component in order to meet particular functional and engineering requirements or protect against environmental degradation. Stainless steels are used in a diverse range of applications due to their excellent corrosion resistance, formability and st…
O Projeto Minas-Rio, de propriedade da Anglo Ferrous Brazil, prevê a utilização de prensa de rolos para cominuição do undersize do peneiramento (-25,4 mm). Esta é uma aplicação que se torna cada dia mais comum, porém relativamente nova em minério de ferro. Foram realizados estudos no Centro de Pesquisa da Krupp/Polysi…
The structures and electronic states of hydrogenated graphenes with a finite size have been investigated by a density functional theory (DFT) method. Five graphenes of various sizes ( n =2, 4, 7, 14, and 19, where n indicates the number of benzene rings in graphene) were examined as models of a hydrogenated graphene s…
A thermopile sensor composed of 196 pairs of p–n thin film legs was processed on a glass substrate by using successive electrodeposition of the n-type Bi–Te and the p-type Sb–Te thin films. The 5.3-μm thick Bi–Te film, electrodeposited at a constant voltage of -50 mV in the 50-mM electrolyte with the Bi/(Bi + Te) mole…
In this work, we investigated the temperature dependence of short and long-range ferroelectric ordering in Pb0.55La0.30TiO3 relaxor composition. High-resolution x-ray powder diffraction measurements revealed a clear spontaneous macroscopic cubic-to-tetragonal phase transition in the PLT relaxor sample at ∼60 K below t…
High thermal stability of high-power phosphor-converted white-light-emitting diodes (PC-WLEDs) incorporating a Ce:YAG-doped glass as the phosphor layer is demonstrated. An exploring study of lumen loss, chromaticity shift, and transmittance loss of high-power PC-WLEDs with Ce:YAG-doped glass and Ce:YAG-doped silicone…
