Epitaxially grown lanthanum-modified lead zirconate titanate (PLZT) thin films were deposited on r -cut sapphire substrates using an advanced sol–gel method. The methanol addition into sol–gel solutions brought high quality epitaxial growth of PLZT thin films. This film showed high electro-optic (EO) coefficients that…
Carbon-fibre composite (CFC) and tungsten macrobrush armours are foreseen as PFC for the ITER divertor. In ITER the main mechanisms of metallic armour damage remain surface melting and melt motion erosion. In the case of CFC armour, due to rather different heat conductivities of CFC fibres a noticeable erosion of the…
The range of concentration of calcium carbonate in the shells of various freshwater gastropods was determined using ion chromatography. Individuals of Helisoma trivolvis (wild) were collected from three ponds in Pennsylvania and New Jersey; individuals of Physa sp. were collected from one pond in New Jersey; individua…
FOM-Rijnhuizen is building, in cooperation with its Trilateral Euregio Cluster (TEC) partners, a PSI-laboratory to study plasma surface interaction (PSI) under extreme, ITER relevant plasma conditions. The largest linear plasma generator of PSI-lab is Magnum-PSI, and is designed to deliver up to 10 MW m −2 power over…
A systematic investigation of the polymorph−hydrate system for Compound I was carried out with the objective of understanding the phase relationships between the different forms as it relates to crystallization conditions. The ternary phase diagram was determined from solubility and KF measurements of the supernatant…
In the frame of JET's ITER-like wall (ILW) project tungsten coatings on carbon fibre reinforced carbon substrates will be used in the divertor and highly loaded areas in the main chamber. Fourteen different types of samples were produced by physical or chemical vapour deposition and vacuum plasma spray (VPS) with coat…
Abstract Wood polymer nanocomposites were prepared from solid aspen wood, water-soluble melamine-urea-formaldehyde (MUF) resin, and silicate nanoclays. The nanofillers were ground with a ball-mill before being mixed with the MUF resin and impregnated into the wood. The water-soluble prepolymer was mixed with the nanoc…
Abstract This article is devoted to the cold crystallization of filled natural rubber with different types of filler such as carbon black, silica, and grafted silica. A large set of differential scanning calorimetry data is presented with various scanning rates, times, and temperatures of isothermal crystallization to…
A high speed chalcogenide random access memory based on Si 2 Sb 2 Te 5 , which is outstanding in data retention and electrical performance, has been fabricated by 0.18-µm complementary metal oxide semiconductor technology. set and reset times are 31 and 10 ns when the corresponding voltage pulses are 2 and 3.5 V, resp…
Pulsed-plasma polymerization has been used to deposit ultrathin layers of pentafluorophenyl methacrylate by using low duty cycles and low power input. The monomer structure can be retained such that the chemical reactivity of the active ester group could be studied using the reaction with a simple amine. The film prop…
The thermal reduction of Co/Al 2 O 3 catalysts prepared by impregnation of Co(II) nitrate generally leads to migration of cobalt ions into alumina with formation of cobalt aluminate. In order to prevent the latter, it is attempted to reduce cobalt by decomposition of supported precursor salts containing ethylenediamin…
In this paper we consider the hyperbolic relaxation of the Cahn–Hilliard equation ruling the evolution of the relative concentration u of one component of a binary alloy system located in a bounded and regular domain Ω of ℝ 3 . This equation is characterized by the presence of the additional inertial term ∊u tt that a…
Single-walled carbon nanotubes are damaged by low-energy electron and photon irradiation, depending strongly on the diameter. In this study, the formation and healing of the irradiation-induced defects were found to be in competition during irradiation even at room temperature or below. The diameter dependence of the…
The erosion of tungsten and carbon marker layers was studied in the outer divertor of ASDEX Upgrade. The outer strike point area and a large fraction of the outer baffle are net erosion areas for both materials. The net erosion rate of carbon is about 10–20 times larger than the net erosion rate of tungsten. The erosi…
In Brief Liposomes are composed of phospholipids, the basic components of human cell walls. Liposome encapsulation improves a medication's bioavailability, which can extend treatment effects and reduce drug dosing. The therapeutic advantages of liposomal drug delivery, such as the ability of long-circulating liposomes…
Hybrid Density functional calculations have been carried out for Au 10 , Au 10 -H 2 O, Au 10 -O 2 , and Au 10 -H 2 O-O 2 model clusters. The results show that all the Au 10 clusters examined have a weak interaction with H 2 O and neutral and negatively charged Au10 clusters have a weak interaction with O 2 . Moreover,…
Various parameters of dosimetric interest such as mass attenuation coefficients, effective atomic numbers and electron densities of some commonly used solvents such as acetonitrile (C(4)H(3)N), butanol (C(4)H(9)OH), chlorobenzene (C(6)H(5)Cl), diethylether (C(4)H(10)O), ethanol (C(2)H(5)OH), methanol (CH(3)OH), propan…
The effect of introducing a network of distributor channels in a nanoporous catalyst pellet was studied. The diffusivity in the distributor channels is orders of magnitude larger than in the nanoporous material itself. Introduction of distributor channels leads to an increasing volume-averaged diffusivity but a decrea…
Abstract The effect of reactive compatibilization on the mechanical properties of nanosilica filled polypropylene (PP) composites was studied in this work. First, the nanoparticles were grafted with poly(glycidyl methacrylate) (PGMA) by solution free‐radical polymerization, and then melt blended together with PP matri…
A novel transflective liquid crystal display architecture and its system driving schemes are proposed. In the reflective mode, the ambient light is used to readout the displayed images. While in the transmissive mode, a color-sequential light emitting diode backlight is used to eliminate the color filters. Under such…
