Ramie fiber/soy protein concentrate (SPC) polymer (resin) interfacial shear strength (IFSS) was measured using the microbond technique. To characterize the effect of plasticization, SPC resin was mixed with glycerin. Fibers were also treated with ethylene plasma polymer to reduce fiber surface roughness and polar natu…
Luminescent properties of and doped phosphors were studied. In the doped system the solid solution extends to but in the doped system the solid solution range is not over the content of For doped samples, the photoluminescence (PL) increases about 30% and cathodoluminescence (CL) increases about 10%. Additionally the…
The effect of intrinsic strain on grain growth in Cu thin films was studied by both plan-view and cross-sectional scanning ion microscope in a focused ion beam system. Significant grain growth with bimodal grain size distribution was observed during room temperature storage in the Cu films which were deposited on the…
Influences of sheet electron beam irradiation on brittleness, fracture load and fracture toughness were studied for silica glass surface. The irradiation, which is one of short-time treatments at low temperature below boiling point of water, restrained the brittleness and enhanced fracture load and fracture toughness…
Ordered mesoporous silica containing 3-chloropropyl groups was prepared by a direct synthetic approach involving hydrolysis and co-condensation of tetraethylorthosilicate (TEOS) and 3-chloropropyltrimethoxysilane in the presence of the triblock copolymer P123 as the structure-directing agent and under acidic condition…
A new host porphyrin bearing four permethyl-beta-cyclodextrin moieties for multi-porphyrin assembly forms a unique 2 : 2 assembly with the tetra-anion of tetrakis(p-sulfonylphenyl)porphyrin (TPPS) in aqueous solution.
The ionic transport in a series of 0.2 [X Na2O·(1 − X)Rb2O]·0.8B2O3 glasses has been studied by measuring both the electrical conductivity of these glasses and the tracer diffusivities of 22Na and 86Rb as functions of composition and temperature. At constant temperature (380 °C) the tracer diffusivities of 22Na and 86…
For recycling steel work dust and improving blast furnace (BF) performance, a few types of non-spherical carbon-iron oxide agglomerates were manufactured in laboratory scale and their strength and reducibility were evaluated using a shatter and a tumbler tester, a simulator for lumpy zone in BF and a softening/melting…
The copper precursors bis-hexafluoroacetylacetonato-copper vinyl-trimethyl-silane-copper(I)-hexafluoroacetylacetonate (hfac)Cu(VTMS), 2-methyl-1-hexen-3-yne-copper-hexafluoroacetylacetonate (hfac)Cu(MHY), and dimethylbutene-copper(I)-hexafluoroacetylacetonate (hfac)Cu(DMB) are compared with respect to deposition rates…
The synthetic flavylium salt 7-(N,N-diethylamino)-4'-hydroxyflavylium tetrafluoroborate gives rise in aqueous solution to a complex network of chemical reactions driven by pH. The system was studied by 1H NMR, single crystal X-ray diffraction, steady state and transient UV-Vis spectrophotometry as well as stopped flow…
New conducting polymers, including poly[thieno[3,2-b][1]benzothiophene] (poly-TBT) and poly [6-methoxythieno[3,2-b][1]benzothiophene] (poly-MeOTBT) were electrosynthesized by anodic oxidation of the corresponding monomers in 0.1 M LiClO4 acetonitrile solution. Poly-TBT and poly-MeOTBT electroactive films were formed o…
We have investigated the complexation of lanthanide ions (Nd3+, Eu3+, Gd3+, Tb3+, Dy3+) with three cyclam-based ligands (cyclam = 1,4,8,11-tetraazacyclotetradecane), namely 1,4,8,11-tetrakis(naphthylmethyl)cyclam (1), and two dendrimers consisting of a cyclam core appended with four dimethoxybenzene and eight naphthyl…
The multi-layered electroluminescent device consisting of Eu(TTA)3(2,2′-bipyridine mono N-oxide) (TTA = 2-thenoyltrifluoroacetonate) as the red dopant exhibited an impressive current and power efficiency at a brightness of 100 cd m−2 and voltage-independent spectral stability.
The structure and orientation of polymer and clay platelets in multilayered, micrometer-thick nanocomposite films was investigated by means of scanning electron microscopy (SEM), atomic force microscopy (AFM), optical microscopy and small-angle neutron scattering (SANS). Microscopic and scattering methods complementar…
Direct liquid crystal templating from non-ionic polyoxyethylene surfactants has been utilised to produce well-defined birefringent films of nanostructured cadmium telluride films which displayed good optical properties as evidenced by UV/VIS reflectance spectroscopy.
4,4'(5')-Bis[2-(9-anthryloxy)ethylthio]tetrathiafulvalene bearing an electron-rich tetrathiafulvalene unit and a luminophore of anthracene shows a highly selective and sensitive chemiluminescence response to singlet oxygen.
The synthesis of the first tetraaza[3,3]ferrocenophane, from the previously unreported 1,1'-bis(triphenylphosphoranylidenamino)ferrocene and its conversion into a nitrogen-rich [2,2]bis[3,3]ferrocenophane is described. The electronic behaviour of these multinuclear ferrocenophanes indicates a strong electronic couplin…
A 30 vol% aqueous suspension of SiC/Al2O3/Y2O3 (1/0.02/0.016 volume ratio) system was consolidated by filtration through gypsum mold. The green compact was hot-pressed at 1700–1900°C under a pressure of 39 MPa in an Ar atmosphere. The sintering mechanisms were discussed based on the analysis of shrinkage curves of SiC…
A (2+1)D kinetic Monte Carlo (KMC) code was developed for coarse-grained as well as atomic-scale simulations that require detailed consideration of complex surface-reaction mechanisms associated with electrodeposition of copper in the presence of additives. The physical system chosen for simulation is similar to that…
We report a simple, one step and efficient method to deposit Si nanoparticles on the surface of in situ formed carbon spheres. This report emphasizes Si deposition on carbon spheres from the thermal decomposition of TEOS at 700 °C in a closed Swagelok cell in an inert atmosphere.
