The area under the glow curve (no thermal quenching and constant dose) is conserved only in TL–time plots and is not conserved in TL–temperature plots, but for a given heating rate, the glow peak height is same in time as well as in temperature plots and the glow peak height increases with increasing heating rate. How…
Abstract The blend of polypropylene (PP) and atactic polystyrene (PS) hybrid with nano‐ceria (CeO 2 ) was prepared for fine dyeable fiber. Nano‐CeO 2 modified with stearic acid was in situ added to PS by radical suspension polymerization. The dispersion of hy‐PS with nano‐CeO 2 in the PP crystals was investigated. The…
Abstract Polybutadiene (BR) and styrene–butadiene (SBR) rubbers containing the same loading of precipitated silica nanofiller were prepared. The silica surfaces were pretreated with bis(3‐triethoxysilylpropyl) tetrasulfide to chemically bond the silica to the rubber. The rubber compounds were mixed together for differ…
We present computer simulations of the Gay-Berne model with a strong terminal dipole. We report the existence of different stable antiferroelectric interdigitated bilayered phases in this model with diverse in-plane organization. The occurrence of these phases depends crucially on the value of the molecular elongation…
Abstract Monomeric Schiff base derived from salicylaldehyde and 1,3‐diaminopropane was subjected to polycondensation reaction with formaldehyde and piperazine in basic medium. The resin was found to form polychelates readily with Mn(II), Co(II), Ni(II), Cu(II), and Zn(II) metal ions. The materials were characterized b…
The structural, electrical, and magnetic properties of epitaxial thin films of a Heusler compound Fe 2 VSi on (001) MgAl 2 O 4 and MgO substrates were investigated. Structural characterization revealed that the films on MgAl 2 O 4 (the lattice mismatch to Fe 2 VSi of 0.7%) were in tetragonally strained states, while t…
In this study, the effect of SiO 2 doping on the sintering behavior, microstructure, and dielectric properties of BaTiO 3 ‐based ceramics was investigated. Silica was added to (Ba 0.96 Ca 0.04 )(Ti 0.85 Zr 0.15 )O 3 (BCTZ) powder prepared using the solid‐state method. SiO 2 ‐doped BCTZ ceramics with a high density and…
Abstract Blends of poly(butylene terephthalate) (PBT) with poly(acrylonitrile‐butyl acrylate‐styrene) (ABAS) were characterized by differential scanning calorimetry, infrared, thermogravimetric analysis, and wide‐angle X‐ray diffraction (WAXD) studies. Addition of ABAS polymer to PBT improved the thermal stability of…
Microscopic models of classical degrees of freedom coupled to noninteracting fermions occur in many different contexts. Prominent examples from solid state physics are descriptions of colossal magnetoresistance manganites and diluted magnetic semiconductors, or auxiliary field methods for correlated electron systems.…
We succeeded in making a nanometer scale height standard by using an atomically controlled diamond surface; an equilateral triangular island with bi-atomic layer steps of (111) diamond on an atomically flat surface. This standard of diamond gives us an absolute digit scale, with 0.206 nm steps determined by its crysta…
The purpose of this study was to investigate the recovery of surfactants using a multistage foam fractionator for three types of surfactants: cationic (cetyl pyridinium chloride, CPC); anionic (sodium dodecyl sulfate, SDS); and nonionic (polyoxyethylene(20 Princen , H.M. ; Mason , S.G. ( 1965 ) Shape of a fluid drop a…
Abstract Polymer nanocomposites based on poly (ethylene 2,6‐naphthalate) (PEN) and carbon nanotubes (CNTs) were prepared by direct melt blending with a twin‐screw extruder. Dynamic thermogravimetric analysis was conducted on the PEN/CNT nanocomposites to clarify the effect of CNTs on the thermal decomposition behavior…
Abstract Cross‐linked zein has been produced using glyoxal (GLY) as the cross‐linking reagent via reactive extrusion for the first time in a twin screw extruder using dilute sodium hydroxide as catalyst. Tri(ethylene glycol) was used as a plasticizer for various items. The extrudate was then ground and processed using…
Abstract A series of low‐density polyethylene (LDPE) antibacterial functional plastics were prepared by mechanical blending with commercial chitosan (CS), self‐made water‐soluble chitosan (W‐CS), and microchitosan as antibacterial agents. The effects of the antibacterial agent content on the elongation at break of the…
Abstract In this study, we use PMMA, tetraethoxysilane and titanium ethoxide to prepare tertiary nanocomposites via non‐hydrolytic sol–gel method. Boron trifluoride monoethylamine was used as catalyst. Silica and titanium dioxide are incorporated into nanocomposites to improve the thermal stability. Thermogravimetric…
Abstract Under mild conditions with the aid of ultrasonic, multi‐walled carbon nanotubes (MWNTs) have been functionalized by mixed acid treatment which was proved by FTIR and XPS. According to SEM, acid treatment on MWNTs decreased the thickness of the membrane. However, no devastating damage and fracture happened on…
We present a simple method to prepare hexagonally packed metallic nanocylinders based on gold nanoparticles embedded in a copolymeric matrix. The gold nanoparticles are generated selectively within the P4VP-rich cylindrical domains of a polystyrene-b-poly-4-vinylpyridine (PS-b-P4VP) diblock copolymer. In order to achi…
Evaporation and sliding behaviors of water droplets were investigated on smooth and rough fluoroalkylsilane coatings. The rough coating possesses nanoscale roughness and chemical heterogeneity on its surface. Evaporation behaviors for these two coatings differed when nanoliter-scale droplets were used, although they w…
In this paper, we numerically study bound electron states induced by long-range Coulomb impurities in gapped graphene and quasibound states in the supercritical region based on the lattice model. We present a detailed comparison between our numerical calculations and the prediction of quantum electrodynamics $2+1(\tex…
Inhibition of acetyl-CoA carboxylase (ACC) may prevent lipid-induced insulin resistance and type 2 diabetes, making the enzyme an attractive pharmaceutical target. Although the enzyme is highly conserved amongst animals, only the yeast enzyme structure is available for rational drug design. The use of biophysical assa…
