Abstract For polycrystalline Ti‐51.8Ni (at.%) specimens annealed at 473 and 943 K, the microstructures at room temperature were observed by transmission electron microscopy and the stress‐induced transformation behaviors at low temperatures were investigated by compressive test. The precipitation of Ti 3 Ni 4 was conf…
Abstract Wider zones with close‐knit orientation crystals in high density polyethylene ( HDPE ) parts prepared via the gas‐assisted injection molding ( GAIM ) process were obtained under high cooling gas pressure. In this study, compressed nitrogen, as a cooling medium, was introduced to retain a high cooling rate of…
Carboxylated nitrile butadiene rubber (XNBR)–based nanocomposites with varying amounts of nanokaolin were produced by latex stage mixing. Sonication of the unmodified kaolin and the technique adopted for the preparation of the composite have helped to get a uniform dispersion of clay in XNBR matrix. Nanokaolin caused…
Structural stability of a transparent conducting oxide CuLaO2 at high pressures is investigated using in-situ Raman spectroscopy, electrical resistance, and x-ray diffraction techniques. The present Raman investigations indicate a sequence of structural phase transitions at 1.8 GPa and 7 GPa. The compound remains in t…
A series of novel water-based UV-curable polyurethane dispersions (UV-PUDs) were synthesized by acetone process with anionic and nonionic stabilization in combination, which can address the requirements of volatile organic compounds (VOCs) directives for both indoor and outdoor applications. The nonionic stabilization…
Inorganic surface ligands such as metal chalcogenides ligand SnS 4 4– and metal free ligand S 2– were introduced for CdSe quantum dot sensitized solar cell (QDSSC) applications. The SnS 4 4– ligand QDs were successfully deposited onto TiO 2 photoanode through metal ion coordination. In solution, metal–ammonia complexe…
In this study, micronized organo‐montmorillonite (OMMT) suspension was prepared with sodium‐montmorillonite (Na‐MMT), didecyl dimethyl ammonium chloride, and dispersant polyethylene glycol 1000 by a ball‐milling process. Then, wood flours (WFs) were impregnated with prepared OMMT suspension at a concentration of 0.5,…
Artificial magnetism enables various transformative optical phenomena, including negative refraction, Fano resonances, and unconventional nanoantennas, beamshapers, polarization transformers and perfect absorbers, and enriches the collection of electromagnetic field control mechanisms at optical frequencies. We demons…
Heterogenous nanostructures shaped with CdS covered ZnO (ZnO/CdS) core/shell nanorods (NRs) are fabricated on indium-tin-oxide by pulsed laser deposition of CdS on hydrothermally grown ZnO NRs and characterized through morphology examination, structure characterization, photoluminescence and optical absorption measure…
An algorithm involving classical molecular dynamics simulations with mapping and reverse mapping procedure is here suggested to simulate the crosslinking of the polystyrene dissolved in dichloroethane by monochlorodimethyl ether. The algorithm comprises consecutive stages: molecular dynamics atomistic simulation of a…
Phase composition and nanostructure of layered and irregular massive impact diamond grains from the Popigai astrobleme have been investigated by Raman spectroscopy and high-resolution electron microscopy and the conditions of phase transformations are discussed. Several coexisting carbon phases forming tight aggregate…
Silica nanoparticles were synthesized by means of a sol–gel method and generated in ethylene propylene diene monomer rubber (EPDM) by in situ synthesis. The properties were determined using scanning electron microscopy, attenuated total reflectance Fourier‐transform infrared spectroscopy, thermogravimetric analysis, t…
Using the coupled series expansion method developed in this paper, we have investigated the quantum behavior of Coulomb impurity states under external electric and magnetic fields in graphene. Under magnetic field, we have obtained an accurate full spectrum of the attractive and repulsive Coulomb impurities for both m…
Crystallographic orientations determine the optical, electrical, mechanical, and thermal properties of crystals. Control of crystallographic orientations has been studied by changing the growth parameters, including temperature, pressure, proportion of precursors, and surface conditions. However, molecular dynamic mec…
A major challenge in muscle tissue engineering is mimicking the ordered nanostructure of native collagen fibrils in muscles. Electrospun nanofiber constructs have been proposed as promising candidate alternatives to natural extracellular matrix. Here, we introduce a novel method to fabricate a two-dimension (2D) sheet…
Ba6Zn6ZrS14 was synthesized by a traditional salt-melt method with KI as flux. The pale yellow crystals of Ba6Zn6ZrS14 crystallize in the tetragonal space group I4/mcm with a=16.3481 (4) Å and c=9.7221(6) Å. The structure features unique one-dimensional parallel [Zn6S9](6-) and [ZrS5](6-) straight chains. The D2h-symm…
Complexation between 5,10,15,20-tetrakis(4-sulfonatophenyl)porphyrin (TPPS) and poly(ethylene glycol)-block-poly(L-lysine) (PEG-b-PLL) was performed via electrostatic interaction. Two kinds of primary arrays of TPPS with different supramolecular chirality induced by PLL were obtained in the resultant complex by invert…
We report a microsecond electro-optic response in an anisotropic-polymer/liquid-crystal composite, which forms a homogeneously mixed structure in the nanoscale range owing to the high miscibility between them. The nanocomposite was fabricated by photopolymerizing a nematic liquid crystal (NLC) mixture doped with a cro…
The homometallic hexameric ruthenium cluster of the formula [Ru(III)6(μ3-O)2(μ-OH)2((CH3)3CCO2)12(py)2] (1) (py = pyridine) is solved by single-crystal X-ray diffraction. Magnetic susceptibility measurements performed on 1 suggest that the antiferromagnetic interaction between the Ru(III) centers is dominant, and this…
