Brillouin scattering measurements were performed on liquid methane using diamond anvil cell along five isotherms and at the pressures up to solidification points. Sound velocity, refractive index, and adiabatic bulk modulus of liquid methane as function of pressure were determined with the measurements from the platel…
This document briefly introduces an analytical method commonly used to determine the radiation length of elements, elemental molecules, chemical compounds, mixtures, composite materials and structures. The formulas are reliable in the absence of experimental data, but the experimental assessment should be prioritised…
Modeling of the electric system “architecture” aims to achieve performances of safety, maintenance, operation, and reliability. This paper discusses the criteria in designing special cases, such as roadway tunnels, that need a structured architecture complying with electrical loads extensively distributed and with ins…
Bacterial acyl carrier protein (ACP) is a highly anionic, 9 kDa protein that functions as a cofactor protein in fatty acid biosynthesis. Escherichia coli ACP is folded at neutral pH and in the absence of divalent cations, while Vibrio harveyi ACP, which is very similar at 86% sequence identity, is unfolded under the s…
Sonolysis of stoichiometric mixtures of tris(2,4-pentanedionato)iron, Fe(acac) 3, and tris(2,4-pentanedionato)yttrium, Y(acac) 3 (H 2 O) 3, under Ar atmosphere in tetraglyme led to a colloidal solution from which amorphous Y−Fe−O nanopowders could be precipitated by hexane. These powders are composed of amorphous nano…
The effect of reverse micelle environment on the binding mechanism of 2-(4-(dimethylamino)styryl)-1-methylpyridinium iodide (DASPMI) with Bovine Serum Albumin (BSA) compared with that in buffer solution has been investigated in this paper with the help of steady state and time-resolved emission spectroscopy along with…
Phase separation in salt-free symmetric mixtures of oppositely charged rodlike polyelectrolytes is studied using quasi-analytical calculations. Stability analyses for the isotropic-isotropic and the isotropic-nematic phase transitions in the mixtures are carried out and demonstrate that electrostatic interactions favo…
We report on the fabrication and optical properties of large-scale plasmonic nanocomposite metamaterial directly within glass matrix by thermal electric-field poling of glass. The achieved structure exhibits an enhanced backscattering (see Figure), which has strong dependence on the exposure of the surface to differen…
Myostatin is one of the transforming growth factor (TGF)-β family members and plays inhibitory roles in the development and growth of muscle in mammals. Mammalian myostatins have been studied intensively, considering its medical and industrial potential use. Still, limited information is available about myostatin homo…
Autologous or allogeneic mesenchymal stem cells (MSCs) have been used as one of the potential cell sources for cellular cardiomyoplasty. The adverse microenvironment in acute myocardial infarction, however, is considered a deleterious factor for MSC transplantation and cell survival. Tumor necrosis factor (TNF)-alpha…
In this letter, we report the fabrication of microbelts through the coassembly of hexa-2-pyridyl-hexaazatriphenylen (HPHAT), a disklike pi-conjugated molecule, with primary alkyl ammonium triflate. The strategy is first to construct hydrogen-bonded complexes between HPHAT and primary alkyl ammoniums to mimic covalentl…
The decomposition of levofloxacin was performed in an aqueous solution under ultrasound irradiation. The effect of operating conditions, including pH value, reaction time, initial concentration, and ultrasound power on the chemical oxygen demand (COD) removal rate was examined at room temperature (23 +/- 2 degrees C).…
With the aim of getting insights into the peculiar electronic, structural, and photophysical properties of four expanded pyridinium systems of potential use as electron acceptors in supramolecular architectures, their electronic and geometrical structures, at both the ground and the excited states, were investigated b…
Abstract-The combination of tetragonal ZrO2(t-ZrO2) and amorphous Al2O3was explored as the gate dielectric for Si-based MOS devices. Because of the absence of a ZrSiO4and/or ZrSi interfacial layer, the thermally stable t-ZrO2/Al2O3/Si stack is more eligible than the Al2O3/t-ZrO2/Si stack for the gate dielectric since…
The effects of intermolecular interactions on the electronic properties of bis-triisopropylsilylethynyl-substituted (TIPS) anthracene, tetracene, and pentacene are obtained from comparison of the ionization energies measured by solid-phase ultraviolet photoelectron spectroscopy (UPS) with the ionization energies measu…
Isolated vanadia clusters supported on titania catalyze the oxidation of methanol to formaldehyde. We used density functional theory to determine the mechanism of this reaction and found a new pathway for the dissociative adsorption of methanol and the dehydrogenation of the methyl group. In this mechanism, methanol a…
The applicably of multi-objective optimization to ellipsometric data analysis is presented and a method to handle complex ellipsometric problems such as multi sample or multi angle analysis using multi-objective optimization is described. The performance of a multi-objective genetic algorithm (MOGA) is tested against…
The spectroscopic and structural characteristics and the relative reactivity of several Tp Ms Cu(olefin) (olefin = ethylene, 1, 1-hexene, 2, allyl ethyl ether, aee, 3, cyclohexene, 4, and styrene, 5 ) complexes bearing the bulky hydrotris(3-mesitylpyrazolyl)borate ligand have been examined. Experimental data, includin…
Abstract The triplet exciton and polaron dynamics in phosphorescent dye (PtOEP) blended polymer (MEH‐PPV) photovoltaic devices are investigated by quasi‐steady‐state photo‐induced absorption (PIA) spectroscopy. According to the low‐temperature PIA and photoluminescence (PL) results, the increase in strength of the tri…
Recently, a single-crystal field-effect hole mobility of about 1.0 cm 2 /(V s) has been measured for the tetraphenylbis(indolo[1,2- a ])quinoline (TPBIQ) crystal. TPBIQ can be considered as almost the dimer of 5,7-diphenylindolo[1,2- a ]quinoline (DPIQ), but the experimental hole mobilities differ markedly. Here, base…
