ABSTRACT This study reports the one‐step reactive melt mixing preparation of organic–inorganic hybrid based on maleic anhydride‐grafted polyethylene and 3‐(2‐aminoethyl)aminopropyl‐heptaisobutyl substituted polyhedral oligomeric silsesquioxane, (NPOSS), as well as on low‐density polyethylene and allyl‐heptaisobutyl‐PO…
Fiber membranes prepared from jute fragments can be valuable, low cost, and renewable. They have broad application prospects in packing bags, geotextiles, filters, and composite reinforcements. Traditionally, chemical adhesives have been used to improve the properties of jute fiber membranes. A series of new laccase,…
Abstract Previously we have determined the lowest-energy structures and full vibrational spectra of Cu N with N up to 150 atoms by means of an unbiased-structure-optimization approach combined with the analytical formulas of the embedded-atom total-energy method and the harmonic superposition approximation. Here, we e…
Abstract C24H16N3O11Co2, monoclinic, P21/n, a = 7.3343(2) Å, b = 42.2275(12) Å, c = 7.5118(2) Å, β = 100.988(3)°, V = 2283.82(11) Å3, Z = 4, R gt (F) = 0.0365, wR ref (F 2 ) = 0.1142, T = 293(2) K.
The aim of this study is to establish a measurement method of oxygen partial pressure in fuel electrodes of solid oxide fuel cells (SOFCs) to clarify a mass transfer mechanism in SOFCs. A sensor, which was made of a platinum wire coated with zirconia, was inserted into the fuel electrode to measure the oxygen partial…
Abstract C22H16N2Br2Pb, monoclinic, C2/c, a = 32.262(11) Å, b = 4.2743(15) Å, c = 16.205(6) Å, β = 115.582(4)°, V = 2015.5(12) Å3, Z = 4, R gt (F) = 0.0578, wR ref (F 2 ) = 0.1163, T = 296(2) K.
Abstract Screen printing is a method commonly used for making electrodes for crystalline silicon solar cells. Although the screen-printing method is fast and easy, screen-printed electrodes have a porous structure, high contact resistance, and low aspect ratio. On the other hand, plated electrodes have low contact res…
Thioxanthone–anthracene (TX-A) was previously synthesized and used as an initiator for the polymerization of acrylates and methacrylates in air atmosphere. Photodimerization of TX-A was carried out in benzene under light irradiation of >350 nm, and dimer (diTX-A) formation was followed by UV–vis, fluorescence and phos…
The results of investigations of the effect of the amount and composition of the exothermic mixture in the filler of the powder strips, produced with different rolling parameters, on the melting parameters and the transition of alloying elements from the powder strip to the deposited metal are presented.
TiN coatings were deposited with various Ar/N2 gas flow ratios by arc ion plating. Coating microstructure and mechanical properties were investigated through grazing incidence x-ray diffraction (GIXRD), scanning electron microscopy, digital microscopy, nanoindentation, and nanoscratch test. GIXRD indicated that TiN co…
Microvolume anion-exchange porous polymer disk-packed cartridges were prepared for Am/Np separation, which is required prior to the measurement of Neptunium-237 ((237)Np) with inductively coupled plasma mass spectrometry (ICPMS). Disks with a volume of 0.08 cm(3) were cut out from porous sheets having anion-exchange-g…
Abstract We found that inhomogeneous epitaxial growth in a superlattice near a Si substrate creates an area where local leakage current occurs at the interface between an AlGaN surface and a Schottky electrode. Here, electroluminescence (EL) through a transparent gate of an AlGaN/GaN high-electron-mobility transistor…
The temperature dependence of the relaxation dynamics in the bilayer thin film heterostructure composed of multiferroic ${\mathrm{BiFeO}}_{3}$ (BFO) and superconducting ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7}$ (YBCO) grown on a (001) ${\mathrm{SrTiO}}_{3}$ substrate is studied by a time-resolved pump-prob…
A novel sulfur oxidizer, strain wk12T, was isolated from an industrially synthesized lead (II) sulfide. The G+C content of the genomic DNA was around 58.5 mol%. The major components in the cellular fatty acid profile were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), C16 : 0 and summed feature 8 (C18 : 1ω7c and/or…
Photoconductivity (PC) of InxGa1-xN has been systematically studied as a function of Indium(In) composition (x) under super-band gap excitation at room temperature. A negative PC has been observed in InN and high In-composition InxGa1-xN, whereas the PC gradually changed to be positive with decreasing x. Transition fr…
Chemically functionalized surfaces are studied for a wide range of applications going from medicine to electronics. Whereas non-magnetic surfaces have been widely studied, functionalization of magnetic surfaces is much less common and has almost never been used for spintronics applications. In this article we present…
We report the synthesis, spectroscopy and X‐ray structural characterization of seven new mixed alkyl‐perfluoroalkyl silver tris(pyrazolyl)borate complexes with the general formula TpRF,CH₃Ag, where RF = CF3 or C2F5. The metal is partly encapsulated in a fluorine‐rich environment and exhibits high Lewis acidity, allowi…
Gallium(III) tetraphenylporphyrinates (TPP) containing anionic sulfur ligands have been prepared and characterized in the solid state and solution. The complexes serve as structural models for iron(III) heme sites containing sulfur coordination that otherwise prove challenging to synthesize due to the propensity for r…
To fabricate stable photoresponsive films and devices, a cross-linked network that firmly fixes the position of the chromophores is an ideal structure, because aggregation and/or phase separation effects of chromophores in matrix can be effectively restrained in such robust films. Herein, the in situ electrochemical d…
Orientation and order of distinct molecular subunits in solid layers of the high mobility n-type copolymer poly[ N, N ′-bis(2-octyldodecyl)-1,4,5,8-naphthalenediimide-2,6-diyl]-5,5′-(2,2′-bithiophene) P(NDI2OD-T2) are investigated by means of infrared transition moment orientational analysis. This novel spectroscopic…
