Abstract The present paper deals with the reflection of waves incident at the surface of a transversely isotropic micropolar medium under the theory of thermoelasticity of GN types II and III. The wave equations are solved by imposing proper conditions on the components of displacement, stresses, and temperature distr…
Abstract Core–satellite nanostructures made of gold nanoparticles were fabricated on glass substrates by controlled immobilization of the nanoparticles and VUV irradiation. Coupled SPR absorption between core and satellite nanoparticles was observed, depending on the length of the dithiol linkers. These satellite nano…
Ionic liquids comprising cationic cobalt(III) complexes [Co(acacen)L2][Tf2N] (L = 3-butylpyridine (1), 1-butylimidazole (2); acacen = N,N′-bis(acetylacetone)ethylenediamine, Tf2N = bis(trifluoromethanesulfonyl)amide) were prepared. 1 is a liquid at room temperature and exhibits a glass transition at −12 °C, whereas 2…
In the present work, it is attempted to derive a macroscopic constitutive law for the elastic deformation of granular materials, based on microscopic considerations. For the sake of simplicity, the solution is restricted to two dimensions, that is, a random assembly of infinitely extended cylinders. After examining pa…
Melting in finite size systems is an interesting but complex phenomenon. Many factors affect melting and owing to their interdependencies it is a challenging task to rationalize their roles in the phase transition. In this work, we demonstrate how structural motif of the ground state influences melting transition in s…
ABSTRACT This article deals with the structure and mechanical properties of blends of an amorphous copolyester (PCTG) and an amorphous polyamide (aPA) which were directly prepared during the plasticization step of an injection molding process. The blends were composed by an almost pure aPA phase, and a PCTG‐rich phase…
A single crystal of the indium-rich intermetallic compound EuPtIn 4 has been grown by a high-temperature solution growth method, with molten indium as solvent. The crystal structure of the compound was solved from the single crystal X-ray diffraction data and it is found that EuPtIn 4 crystallizes in the orthorhombic…
We report a hypothetical sp2-rich high-density amorphous carbon (sp2-HDAC) phase that is achieved from glassy carbon at high pressure and temperature (151 GPa and nearly 4100 K) based on molecular dynamics calculations. The systemically theoretical investigation demonstrates that the sp2-HDAC phase exhibits a high inc…
We propose a method to utilize colloidal quantum dots (QDs) as a swept light source for hyperspectral microscopy. The use of QD allows for uniform multicolor emission which covers visible-NIR wavelengths. We used 8 colors of CdSe/ZnS and CdTe/ZnS colloidal quantum dots with the peak emission wavelengths from 520 nm to…
Nuclear resonance vibrational spectroscopy (NRVS) is a powerful technique that can provide geometric structural information on key reaction intermediates of Fe-containing systems when utilized in combination with density functional theory (DFT). However, in the case of binuclear non-heme iron enzymes, DFT-predicted NR…
The reaction of 1 : 4.4 M proportion of cis-[ReO2I(PPh3)2] and 4-aminopyridine (ampy) in acetone–water gives trans-[ReO2(ampy)4]I·2H2O (1a) in 85% yield. 1a has been characterized by C, H, and N microanalyses, FT-IR, UV–vis, 1H NMR spectroscopy, and molar conductivity. The X-ray crystal structure of 1a reveals an octa…
We report ultraviolet electroluminescence from a hetero p-n junction between a single ZnO microsphere and p-GaN thin film. ZnO microspheres, which have high crystalline quality, have been synthesized by ablating a ZnO sintered target. It was found that synthesized ZnO microspheres had a high-optical property and exhib…
ABSTRACT Cisplatin was incorporated into polymeric carriers through the coordination of Pt with the carboxylic groups of methoxy‐poly(ethylene glycol) (mPEG)‐block‐poly[(2‐carboxy‐ethylsulfanyl)‐propyl glycidyl ether] (PCPGE). The mPEG‐b‐PCPGE/Pt complexes with a Pt content of 14 wt % could self‐assemble into spheric…
The niobized layer was formed on Q235 low-carbon steel by double-glow plasma surface niobizing to improve its wear resistance. The microstructure, phase composition, and microhardness were determined. The friction and wear properties of the niobized samples and the untreated alloys were tested on a ball-on-disk tribom…
PURPOSE: This study was aimed to assess the effects of High Intensity Focused Ultrasound (HIFU) thermal ablation on tumor T1ρ . METHODS: In vivo T1ρ measurements of murine tumors at various spin-lock amplitudes (B1 = 0-2000 Hz) were performed before (n = 13), directly after (n = 13) and 3 days (n = 7) after HIFU treat…
Water uptake in porous low-k dielectrics has become a significant challenge for both back-end-of-the-line integration and circuit reliability. This work examines the effects of water uptake on the fracture behavior of nanoporous low-k organosilicate glass. By using annealing dehydration and humidity conditioning, the…
Poly (p‐phenylene benzobisoxazole)/carbon nanotube (PBO/CNTs) composites have already been experimentally synthesized with the outstanding mechanical and electrical properties. Carboxylic carbon nanotubes (CNT‐COOH), obtained by acid treatment, can better disperse than pristine nanotubes in PBO matrix, which is estima…
Here we investigated the protective role of caffeic acid phenyl ester (CAPE) on erythrocyte indices and osmotic resistance, blood coagulation, hepato-renal function and antioxidant status in cadmium (Cd) toxicity in rats. Cd intoxication was induced by intraperitoneal injection (i.p.) of cadmium chloride (1 mg/kg/day)…
We theoretically investigate the thermoelectric effects in an Aharonov-Bohm ring with a serially coupled double quantum dot embedded in one arm. An external magnetic field is perpendicularly applied to the two dots. Using the nonequilibrium Green's function method in the linear-response regime, we calculate the charge…
A simple synthetic strategy for synthesis of new series of hetarylazo-heterocycles is described. The effects of solvent on their electronic absorption spectra were analyzed using Kamlet-Taft equation. The results of fitting coefficients indicated that the solvatochromism of the studied compounds is mainly due to the s…
