In this paper, we have successfully fabricated low-temperature polycrystalline silicon thin-film transistor (LTPS-TFT) nonvolatile memory devices employing high-κ Eu2O3and Y2O3films as the charge trapping layer. The LTPS-TFT memory device uses band-to-band tunneling-induced hot hole injection and gate Fowler-Nordheim…
Experimental and modeled dependencies of the induced refractive index on dosage of UV exposure in photo-thermo-refractive glass for different thermal treatment regimes are presented. Resulting spatial profiles of refractive index modulation in a reflecting Bragg grating recorded by a holographic technique are computed…
Abstract The objective of this study was to investigate the effects of mono‐ and polyvalent cations on sorption of the two hydrophobic compounds nonylphenol (NP) and phenanthrene (Phe). To this end, exchange sites of a sandy soil were saturated with either Na+, Ca2+, or Al3+ and excess salts were removed by washing. T…
The magnetization behavior of long nanowires with square cross section under the influence of strong perpendicular spin-polarized current is studied theoretically. The study is based on Landau-Lifshitz-Slonczewski phenomenology. Without the current the wire is magnetized uniformly along its axis. For small currents th…
ABSTRACT O‐(2,3‐dihydroxypropyl) cellulose (DHPC) samples were synthesized by etherification of cellulose with glycidol (GLY) in a NaOH/urea aqueous solution system under different reaction conditions, so that they had different degrees of ether substitution (DS) in both the overall and regional distributions. The cha…
This study examines the use of poly(o‐toluidine) (POT) coatings and poly(o‐toluidine)/oxidized multi‐walled carbon nanotubes (POT‐MWCNT) composite on 304 stainless steel for corrosion protection. The POT coatings and its composite were synthesized on steel substrates under cyclic voltammetric conditions. These coating…
Here we performed structural and biochemical analyses on the TK2285 gene product, an uncharacterized protein annotated as a member of the ribokinase family, from the hyperthermophilic archaeon Thermococcus kodakarensis . The three-dimensional structure of the TK2285 protein resembled those of previously characterized…
Abstract A series of cationic starch (CS-8)-based styrene (St) acrylate latex preparations was prepared by the core-shell emulsion polymerization method. The latex was used in the surface-treatment of decorative base papers, for good printability and absorbability. CS-8, which has a low relative viscosity, was used as…
ABSTRACT Polystyrene (PSt) radicals and poly(methyl acrylate) (PMA) radicals, derived from their monobrominated precursors prepared by atom transfer radical polymerization (ATRP), were formed in the presence of the radical trap 2‐methyl‐2‐nitrosopropane (MNP), selectively forming PSt‐PMA diblock copolymers with an alk…
Abstract We present an extended methodology of the quantum mechanical/molecular mechanical framework with Metropolis Monte Carlo method (QM/MM-MC), in which close surrounding solvent molecules are included in QM subsystem to evaluate quantitatively the solvation free energy change. The neutral (N) and zwitterionic (Z)…
Some of the more efficient accretion processes in astrophysics are associated with the presence of accretion disks. Such disks are found in protostars; in various types of binary stars, including low- and high-mass X-ray binaries; in dwarf novae or cataclysmic variables; and in classical novae. They are also believed…
The article presents the first attempt to CVD-aluminise alloys based on an intermetallic phase Ti48Al2Cr2Nb. Moreover, it includes initial results of producing VPA-deposited aluminide coating in industrial environment. Microstructure and phase analyses of the obtained coatings have been conducted. The chemical and pha…
Dispersed 1-tetradecyl-3-methylimidazolium chloride ([C 14 MIM]Cl) ionic liquid (IL) is insoluble with alkane solvents: 1-hexane, 1-octane, 1-decane, and 1-dodecane. Aggregation of IL, however, was initiated by adding 1-octanol (molar ratio of IL/octanol is 1/3), and rod-like single crystals grew after several days. C…
The radical initiated hydrosilylation of terminated unsaturated organic molecules on water saturated Si(100)-(2 × 1) is systematically studied using density functional theory (DFT) calculations in the framework of periodic surface model. Two possible radical chain-reaction mechanisms including the H-abstraction from s…
Carbon doping is known to be very effective for enhancing the high‐field properties of magnesium diboride, MgB 2 , but not for the low‐field properties. Here, we report that both the high‐ and the low‐field properties can be improved simultaneously without doping by increasing the initial magnesium partial pressure, b…
Three two-dimensional (2D) and 3D supramolecular coordination architectures based on ternary M(II)-dicyanamide-2-hydroxypyridine systems, [Co(hmpH)2(dca)2] (1), [Cu(hmpH)2(dca)2] (2), and [Mn(hepH)2(dca)2] (3) (dca = dicyanamide, hmpH = 2-(hydroxymethyl)pyridine, hepH = 2-(hydroxyethyl)pyridine), have been synthesized…
La 2 Mo 2 O 9 (LMO) ceramics are synthesized by using a novel isobaric-microwave assisted method. Monoclinic distortion shrinkage was detected according to a smaller thermodynamics parameter enthalpy ( ΔH ) ∼ 3.2 kJmol −1 at the monoclinic-cubic phase transition temperature in these LMO ceramics. Even there is no dire…
Production of primary Al- alloys belong to heavy source fouling of life environs. Care of environment in industry of aluminium connects with the decreasing consumptions resource as energy, materials, water and soil, with increase recycling and extension life of products. Recycled (secondary) aluminium alloys are made…
Abstract Epoxy resin, along with a suitable reinforcement such as glass, is used to manufacture windmill blades by vacuum assisted resin infusion molding (VARIM) process. For the simulation of VARIM process, the sub models are required to describe the rheological and thermochemical behaviour of the epoxy resin. In the…
In this work we characterize an alcohol dehydrogenase (ADH) from the hyperthermophilic archaeon Pyrobaculum aerophilum (PyAeADHII). We have previously found that PyAeADHII has no activity when standard ADH substrates are used but is active when α-tetralone is used as substrate. Here, to gain insights into enzyme funct…
