This paper deals with the investigation of space charge accumulation dynamics in XLPE electrical insulation. In particular, very fast charge packets, i.e., having large mobility, are observed to be injected from both electrodes and to cross the insulation bulk, thereby contributing to heterocharge build-up at the oppo…
In this paper, rectangular shape complementary split ring resonators (CSRRs) with different dimensions are introduced to realize balanced composite right/left handed (CRLH) structure.As the dimensions of CSRRs is altered, the required series capacitance should also be modified and the propagation characteristics will…
The protonation mechanisms of the poly(amidoamine) (PAMAM) andpoly(propyleneimine) (PPI) dendrimers are clarified and related to their molecular structure. The overall proton binding isotherms can be interpreted in terms of a site binding model, which involves a limited number of parameters, and can be used to gain de…
An overview on recent developments in thermal interfaces is given with a focus on a novel thermal interface technology that allows the formation of 2-3 times thinner bondlines with strongly improved thermal properties at lower assembly pressures. This is achieved using nested hierarchical surface channels to control t…
For the first time, pore formation on n-InP͑100͒ has been carried out by galvanostatic treatments in acidic liquid ammonia at 223 K. Voltage oscillations correlated to a specific current line oriented pore morphology have been evidenced by scanning electron microscopy.Whatever the anodic charge, a constant pore depth…
Hydroentanglement is a versatile and relatively little explored method of bonding the fibrous web using high-pressure water jets. These nonwoven structures have an extensive range of applications–for example, wipes, carpet backing, filters, sanitary, medical dressings, and composites. Such applications require certain…
One of the main differences between low-pressure and atmospheric-pressure plasma treatments is that there is little moisture involved in the low-pressure plasma treatment, although moisture could exist at the wall of the vacuum chamber or react with the substrate after plasma treatment, while in the atmospheric-pressu…
We report quasi-elastic neutron scattering experiments at two resolutions that probe timescales of picoseconds to nanoseconds for the hydration dynamics of water, confined in a concentrated solution of N-acetyl-leucine-methylamide (NALMA) peptides in water over a temperature range of 248 K to 288 K. The two QENS resol…
Single crystalline Sn-doped ZnO nanobelts were successfully synthesized by the carbon thermal reduction deposition process without using any catalyst. XRD investigation confirmed that the products were of the wurtzite structure of ZnO. SEM, EDS, and TEM analyses showed that the Sn-doped ZnO nanostructures contained a…
A new thermal management application of silicon-based thermoelectric (TE) cooler integrated with high power light emitting diode (LED) is investigated in present study. The silicon-based TE cooler herein is fabricated by MEMS fabrication technology and flipchip assembly process that is used for high power LED cooling.…
The authors report on reproducible growth of ZnMgO quantum dots (QDs) by a metal organic chemical vapor deposition method. Mg is introduced into ZnO QDs, as confirmed by x-ray photoelectron spectroscopy and photoluminescence measurements. The size, density, and optical band gap of ZnMgO QDs can be well controlled by s…
Transmission studies for multiple heterostructures consisting of two kinds of single-negative materials inserted with defects are presented. The results show that multiple-channeled filters can be obtained by adjusting the period number m and thicknesses of defects. These structures provide an excellent way to select…
Abstract We have performed a detailed, quantum chemical, decomposition analysis of the physical nature of key interactions in the model enzyme chorismate mutase (CM), for several active conformations produced by high level combined quantum mechanics/molecular mechanics (QM/MM) modeling. In opposition to our previous s…
Bi-functionalized dendrimers leads to highly efficient quantitative proteomics and the determination of protease activities in snake venoms.
We had proposed chemical heat pumps using a reversible calcium sulphate/water reaction system for effective waste energy utilization. However, more reaction kinetics studies are necessary for this reaction system, especially for different atmosphere condition and different materials. As a result, the reaction equilibr…
Dielectric relaxations were investigated for the solid-solution system Ce1-xSmxO2-δ(0.0≦x≦0.5), which is a typical oxide-ion conductor. The dielectric constants showed anomalously large values at low frequencies and high temperatures. Computer simulation clarified that the anomalously large dielectric constant (εr′) o…
SQUID magnetometry and transport measurements combined with crystal structure refinement have been used to examine the variation in superconducting properties (Tc and Meissner fraction) in the molecular superconductor β″-(BEDT-TTF)4[(H3O)Fe(C2O4)3]·C6H5CN on replacing the C6H5CN guest molecule with pyridine (C5H5N). U…
Polypyrrole films doped with dodecylbenzenesulfonate (PPy–DBS) were prepared for effective copper protection by galvanostatical method on an underlayer of polypyrrole doped with oxalate , because PPy–DBS could not be obtained directly on the copper surface by electrochemical methods. Their anticorrosion performance in…

Aliphatic poly(carbonate) glycols (PC-glycols) with different methylene unit lengths were synthesized from ethylene carbonate and 1,3-propanediol, 1,4-butanediol, 1,5-pentanediol, 1,6-hexanediol, 1,7-heptanediol, 1,8-octanediol, 1,9-nonanediol or 1,10-decanediol. The samples were coded 3002, 4002, 5002, 6002, 7002, 80…
