Polyaniline/MnO 2 /graphite felt (PMGF) composite, which can be used as a novel free‐standing, flexible electrode for supercapacitors, was fabricated via a facile electrochemical method. Polyaniline/graphite felt (PANI/GF) electrode was prepared by electropolymerization of PANI onto the GF. Subsequently, manganese dio…
The local structure of SmFe 1− x Ru x AsO 0.85 F 0.15 ( x = 0.0, 0.05, 0.25 and 0.5) superconductors has been investigated by temperature dependent As K-edge extended x-ray absorption fine structure analysis. The effect of Ru substitution remains confined to the iron–arsenide layer but neither the static disorder nor…
Using the quantum chemistry calculation module based on density functional theory (DFT), the stable adsorption states of Ni4 cluster on the surface of α-Al2O3(0 0 0 1) was investigated firstly, and then the most stable adsorption configuration was selected as the representative model of supported Ni4/α-Al2O3(0 0 0 1)…
A free dendrite growth at the Earth's inner core boundary is analyzed using a sharp interface model.A new selection criterion of the dendrite tip's stable growth into non-isothermal binary melt with convection and pressure effects for the 2D and 3D axisymmetric models is derived.The criterion obtained combines known a…
Epitaxial 4H-SiC graphene films for use in ambient gas sensing are fabricated and tested. The sensitivity response to nitrogen dioxide is optimized by varying both operation temperatures and humidity. A relative resistance change response of -45% is obtained upon application of elevated temperatures and a gas mixture…
ABSTRACT A series of 1,3,5‐trialkyl‐benzenetricarboxylamides (BTA‐Rs) with different side‐chain lengths of n ‐alkyl are synthesized to use as nucleating agents of poly (lactic acid) (PLA). Crystallization rate of PLA is detailed discussed in nonisothermal melt‐crystallization with addition of the synthesized nucleatin…
We report on the fabrication and optoelectronic features of Tb3+ doped gadolinium oxide (Gd2O3) nanpowders. The nanosystems were found to exhibit cubic crystalline structure with an average crystallite size in the range of 11–24 nm. Inclusion of Tb3+ into Gd2O3 host has led to suppression of the optical gap but result…
We report the application of partially reduced CuO nanoparticles as Cu-based catalysts for dimethyldichlorosilane (M2) synthesis via the Rochow reaction. The CuO nanoparticles (50–100 nm) were synthesized by a simple precipitation method and partially reduced in a H 2 /N 2 mixture gas to obtain the Cu-based catalyst c…
A series of polycrystalline SmFeAsO 1− x F x bulks ( x = 0–0.25) were synthesized by a one step solid state reaction method at a low heat temperature of 900 ° C, which was about 300 ° C lower than the conventional temperature (∼1200 ° C). The magnetic susceptibility measurements showed single step superconducting tran…
Kurzfassung Das Nitrieren und Nitrocarburieren zeichnet sich durch eine von anderen Verfahren der Randschichttechnik unerreichte Anwendungsvielfalt aus, die sich aus der Struktur nitrierter Randschichten und der Variationsbreite nitrierbarer Werkstoffe ergibt. Die einzigartige Kombination einer dünnen Hartstoffschicht…
We examine the character of the itinerant magnetic transition of DyCo${}_{2}$ by different calorimetric methods, thereby separating the heat capacity and latent heat contributions to the entropy---allowing direct comparison to other itinerant electron metamagnetic systems. The heat capacity exhibits a large \ensuremat…
Seamless observation: Magnetic measurements in a solid-state electrochemical environment have been developed and applied to a mixed-valent chromium Prussian blue analogue (PBA) ferrimagnet. Battery cells containing PBA as a cathode active material were inserted into a SQUID and the PBA reduction during battery dischar…
Time evolution photoluminescence (PL) studies of ferroelectric liquid crystal (FLC) mixtures doped with different concentrations of ZnS and CdS quantum dots (QDs) are carried out. Remarkable enhancement in the PL intensity and a significant shift in the emission band of FLC materials are observed by doping with a suit…
OBJECTIVE: The purpose of this work was to prepare a stable paclitaxel nanosuspension and test it for potential use as a targeted chemotherapeutic. Different particle coatings were employed to assess their impact on cellular uptake in vitro. In vivo work was then performed to demonstrate efficacy in tumor-bearing mous…
Boron and nitrogen substitutional impurities in graphene are analyzed using a self-consistent tight-binding approach. An analytical result for the impurity Green's function is derived taking broken electron-hole symmetry into account and validated by comparison to numerical diagonalization. The impurity potential depe…
We have investigated the failure modes of single crystal aluminium under decaying shock loading by using molecular dynamics simulations. The microstructure evolution during the failure is presented in terms of the central symmetry parameter, and the corresponding pressure and temperature profiles are calculated and di…
ABSTRACT A novel polyarylene ether nitrile terminated with phthalonitrile (PEN‐ t ‐Ph) was synthesized by a simple solution polycondensation of biphenyl and hydroquinone with 2,6‐dichlorobenzonitrile, followed by termination with 4‐nitrophthalonitrile. The PEN‐ t ‐Ph/1,3,5‐Tri‐(3,4‐dicyanophenoxy) benzene (TPh) system…
This study analyses the flexural and impact strength of polypropylene reinforced with stone ground wood pulp (SGWP) and the effect of a maleated‐polypropylene (MAPP) coupling agent on the mechanical properties of these composites. Composites prepared in the absence of the coupling agent showed a very light positive li…
Using scanning tunneling microscopy and spectroscopy, we have analyzed the growth of ZnO thin films on a Au(111) support. Because of the 12% lattice mismatch with the metal beneath, ZnO develops a (0001)-oriented coincidence lattice that gives rise to a well-ordered hexagonal Moiré pattern with 2.2 nm periodicity. Thi…
One-dimensional (1-D) chain complexes constructed by metal-metal bonds containing three types of metal species-platinum, rhodium, and copper-have been rationally synthesized and characterized by single-crystal X-ray analyses and physical measurements. The paddlewheel or lantern type complex, [Rh2(O2CCH3)4] (i.e., [Rh2…
