High-quality m-plane orientated ZnO films have been successfully grown on m-plane sapphire by using radio frequency magnetron sputtering deposition. The introduction of a nanometer-thick, low-temperature-grown ZnO buffer layer effectively eliminates inclusions of other undesirable orientations. The structure character…
During the past decade, a shift of focus onto greener alternatives to petroleum-based plastics has spurred the development of bio-based resins for plastic development. This has led to a positive marketing image for companies making the switch to resins from renewable resources. This shift of focus is further reinforce…
This study reports a green approach toward the synthesis of novel optically active poly(amide-imide)s (PAI)s bearing thiazole moiety, which was formed by the polycondensation reaction of 3,5-diamino- N-(thiazol-2-yl)benzamide and various diacids containing natural amino acids in molten tetrabutylammonium bromide. Diam…
A prospective technology for manufacturing thermoplastic composites is based on hybrid commingled yarns. The hybrid yarns are further processed into semi-impregnated thermoplastic preforms in the form of woven or non-crimped fabrics, which are consolidated and molded in a single processing step. The quality of the com…
Crystallographic structure and magnetic phase diagrams were investigated for single crystals of multiferroic Mn 2 GeO 4 showing successive magnetic transitions at T N1 = 47 K, T N2 = 17 K, and T N3 = 5.5 K. Substantial anomalies of lattice distortion were observed at the respective magnetic transition temperatures. We…
In the last few years research activities have been focused on the modification of fiber properties with nano-scaled additives. One of the most important fields of research is the alteration of mechanical properties such as the tenacity and the specific breaking load. In this study, we determined the influence of nano…
A photochromic diarylethene with N,N-dimethyl substituted group 1a was prepared. 1a showed ring-opening and ring-closing photoisomerization with UV/vis light irradiation. Treatment of 1a with CF(3)COOH produced a protonated diarylethene 1aH. With UV light irradiation, 1aH photoconverted to protonated ring-closed isome…
Various poly(ethylene glycol) monomethyl ether moieties were grafted onto hydrogenated silicon surfaces in order to investigate the influence of the molecular design on the antifouling performance of such coatings. The grafted chains were either oligo(ethylene oxide) chains (EG)(n)OMe bound to silicon via Si-O-C coval…
Zinc oxide (ZnO) nanoparticles have been synthesized by a microwave heating method. The resulting powders were annealed at temperatures from 400°C to 800°C for 4 h. The annealed powders were characterized in terms of their structural, morphological, and optical properties by X-ray diffraction (XRD), Fourier-transform…
It is shown that pre-straining with deformation twinning is a novel approach to enhancing the uniform elongation of a high-strength β-type Ti–15Mo alloy (mass%) with isothermal ω-phase precipitation. Pre-existent mechanical {3 3 2}⟨1 1 3⟩ twins hinder the early onset of plastic instability (necking) after yielding, wh…
Phase-selective synthesis of trivalent lanthanide-doped NaGdF4 nanocrystals, capped by ionic liquid cations bearing long alkyl chains, succeeded via a one-step interface-assisted ionothermal route. Owing to the existence of an interface formed between hydrophobic ionic liquids and ethylene glycol, selectively either p…
On the basis of mean-field theory, we predict that molecular brushes with dendritic side chains ("dendronized polymers") may exhibit the behavior of semirigid polymers capable of lyotropic odering. The apparent persistence length of these molecular brushes is governed by the interactions between dendritic grafts and m…
Abstract Defect structure and transport properties of Co 3 O 4 cobalt oxide have been studied as a function of temperature and oxygen pressure, using marker and thermogravimetric techniques. It has been found that the oxidation of CoO to form Co 3 O 4 follows parabolic kinetic, being thus diffusion controlled. Marker…
Oriental Journal of Chemistry is a peer reviewed quarterly research journal of pure and applied chemistry. It publishes standard research papers in almost all thrust areas of current chemistry of academic and commercial importance. It provides a platform for rapid publication of quality research papers, reviews and ch…
Abstract The interaction of the copper [{3,5‐(CF3)2Pz}Cu]3 and silver [{3,5‐(CF3)2Pz}Ag]3 macrocycles {3,5‐(CF3)2Pz = 3,5‐bis(trifluoromethyl)pyrazole} with 2‐butanone and benzophenone was investigated for the first time by IR and NMR spectroscopy and single‐crystal X‐ray diffraction. New, low‐frequency IR bands for ν…
The degradation mechanism of graphene sheets doped with metal chloride was investigated as a function of the annealing process. The sheet resistance of doped graphene increased from 500–700 Ω sq−1 to 10 kΩ sq−1 and the transmittance at 550 nm decreased from 95% to 87–91% after annealing at 400 °C. Furthermore, the wor…
Surface-enhanced Raman scattering (SERS) from silver nanosculptured thin films (STF) was studied in detail for biosensing. The influences of the nanostructures' sizes, topology, the substrate features, and the preparation conditions on the enhancement were examined. Enhancement factors on the order of 10 7 were obtain…
A homogeneous aqueous dispersion of cellulose nanocrystals (CNs) that is left to evaporate in a Petri dish self-organizes into smectic liquid crystals that are actually liquid multilamellar structures. As evaporation proceeds, the liquid multilamellar structures solidify to become a solid multilamellar film. Each soli…
This article presents an experimental study on the effect of polymeric matrix flow behavior on the properties of the reprocessed wood–plastic composites (WPC) of high-density polyethylene (HDPE) and wood sawdust. WPCs are considered as sustainable materials due to their durability in the environmental conditions and r…
In order to achieve continuous biocatalytic hydration of CO(2), carbonic anhydrase (CA) derived from Rhodobacter sphaeroides was immobilized on electrospun polystyrene/poly(styrene-co-maleic anhydride) (PS/PSMA) nanofibers as cross-linked enzyme aggregates (CLEA). The CA-CLEA maintained more than 94.7% of its initial…
