We report electrical bistability in electrostatic assembly of CdSe nanoparticles. We obtained thin films of the nanoparticles via layer-by-layer electrostatic assembly technique, which provided a nanoscale control to tune the thickness. Devices based on such thin films exhibit electrical bistability along with memory…
This paper presents a circuit-compatible compact model for short channel length (5 nm~100 nm), quasi-ballistic single wall carbon nanotube field-effect transistors (CNFETs). For the first time, a universal circuit-compatible CNFET model was implemented with HSPICE. This model includes practical device non-idealities,…
The experimental results of measurements of electromagnetic wave reflection for some specimens of water foam for various time of their existence in free space for frequency range 38 - 52 GHz are presented. Thickness of specimens was 80 mm, the range of foaming ratio was from 69 till 173. It was possible to select sepa…
Cadmium sulphide (CdS) thin films deposited on indium tin oxide (ITO) substrates were prepared by chemical bath deposition technique by using different conditions to agitate the bath and the substrate. For substrate, an oscillating device working at 37 Hz was adapted to support each ITO substrate in order to agitate t…
Spalling is a wave-induced dynamic fracture phenomenon. The waves can be either one: elastic, elasto-plastic, or shock waves. From a continuum mechanics point of view, fracture mechanics and wave propagation form the main ingredients in the formation of spalls. Recently, however, micro-structural effects have become i…
Abstract Peroxide cure is an important and widely used cure system for rubber. Several properties obtained via peroxide vulcanization are superior and not achievable with sulfur vulcanization, e.g. : aging resistance, no reversion and low compression set. However, other properties such as tensile strength and dynamic…
Electron diffraction was used to study the annealed titanium monoxide TiO1.087 containing the monoclinic ordered phase Ti5O5. The diffraction pattern of titanium monoxide in the (112)* B1 plane of the reciprocal lattice of the parent B1 cubic structure contains not only structural, superstructural, and additional refl…
Two series of very large discotic complexes of tetrakis (2,3,6,7-tetraalkoxy)triphenylenocyaninato copper(II) (abbreviated as ( C n O ) 16 TcCu ; n = 8, 10, 12 and 14) and tetrakis(2,3,6,7-tetraalkoxy)-1,4-diazatriphenylenocyaninato copper(II) (abbreviated as ( C n O ) 16 TzCu ; n = 8, 10, 12 and 14), were synthesized…
Supramolecular triads composed of zinc naphthalocyanine ( ZnNc ) as an electron donor, pyridylfullerenes as primary electron acceptors, and either ferrocene ( Fc ) or N , N -dimethylaminophenyl ( DMA ) entities as second electron donors were constructed via metal-ligand axial coordination. The formation of the supramo…
Abstract The pH-stat technique has been used to study the influence of several natural and synthetic additives containing carboxyl, phenolic, and sulfonic groups on the precipitation of calcium carbonate from supersaturated solutions (Ca=HCO 3 = 5.50 mM, NaCl=0.10 M, pH 8.50, 35°C). The additives investigated were nat…
Thin films of indium oxide 200 nm thick and indium nitride 150 nm thick were produced by reactive sputtering deposition onto soda lime substrates. The Indium cathode was kept under vacuum attached to a high voltage dc. The In xOy films were obtained in argon-oxygen mixture with total pressure between 2 and 7 Pa, curre…
We report on the effect of postdeposition laser annealing of undoped zinc oxide (ZnO) thin films grown by laser assisted molecular beam deposition. Hall-effect measurements show that some undoped ZnO films change from n type with mobility values in the range of 200cm2V−1s−1 to p-type material with mobility value of 73…
This paper reports on the use of liquid hyperbranched aromatic polyester epoxy resin (HTME) as an additive to an epoxy resin/amine system. Four kinds of different molecular weight and epoxy equivalent weight HTME as modifiers in the diglycidyl ether of bisphenol-A (DGEBA) amine systems are discussed in detail. It was…
Membranes in artificial organs and scaffolds for tissue engineering are often coated with biomimetic molecules (e.g., collagen) to improve their biocompatibility and promote primary cell adhesion and differentiation. However, animal proteins are expensive and may be contaminated with prions. Silk fibroin (SF) made by…
To provide a data base for the regulatory guide of light water reactors, behavior of reactor fuels during off-normal and postulated accident conditions such as reactivity-initiated accident (RIA) is being studied in the Nuclear Safety Research Reactor (NSRR) program of the Japan Atomic Energy Agency (JAEA). The paper…
Abstract Dislocations are common defects in both natural as well as in CVD‐grown diamond. Recent advances in the growth of high quality single crystal CVD diamond have led to an increased interest in the atomistic and electronic structure of 〈100〉 dislocations. These dislocations are observed as mixed‐type 45° and pur…
Thermally stimulated currents (TSCs) are measured in amorphous barium titanate thin films deposited by the rf sputtering technique. The TSC global curve is composed of three overlapping peaks in the 0–200°C temperature range. At 50°C, a first TSC peak is observed that can be related to a shallow-trap level. A second p…
Fission gas release (FGR) behavior under rapid heating conditions of high burnup UO2 fuels with developed rim structure has been examined using two different out-of-pile heating techniques with no restraint pressure. The burnups of the fuel specimens were 36–86 GWd/tU. The bare fuel specimens were heated up to 600-1,8…
Application of nanofiber-based nanomats in medicine is attractive and thanks to the 3D nanostructure and the high surface to volume ratio they are excellent for local controlled drug delivery. The use of bioactive bioerodible polymers for developing drug delivery nanomats may allow for drug release and targeting contr…
Abstract Usual rubber products are a composite from rubber and nano-filler ( e.g. carbon black, silica, etc. ), and it is believed that the good dispersion of the nano-filler is the most important issue determining the performance of rubber vulcanizates. So far, transmission electron microscopy (TEM) has been the most…
