This article investigates the relationship between the characteristic radii from an anion nucleus, by comparing RSP (the Shannon−Prewitt anion radius based on Pauling's theory with Goldschmidt's experimental data) with Req, at which the charge densities of one anion and cation respectively are equal in the interatomic…
The effect of collagen tripeptide fragment GER on the adhesion and spreading of mouse embryonic fibroblasts STO to different substrates (polystyrene plastic, poly-L-lysine, fibronectin, gelatin) has been studied. It was found that tripeptide GER was involved in fibroblast adhesion and spreading. The cell response depe…
The heterocyclic ring of N-aryl-4-chloro-1,8-naphthalimides, reported to be resistant to nucleophilic attack, reacts with primary amine nucleophiles at room temperature to give 4-chloro-N-alkyl-1,8-naphthalimides. The reaction is first order in the naphthalimide. The Hammett plot is linear (R(2) 0.996) with a large po…
Compact equivalent circuit models for single‐walled carbon nanotube (SWCNT) bundles are described, and the performance of SWCNT bundle interconnects is evaluated and compared with traditional Cu interconnects at different interconnect levels for through‐silicon‐via‐based three‐dimensional integration. It is shown that…

We successfully synthesize four kinds of ZnO nano/microcrystals including dumbbell microrods, nanoflakes, nanoplates, and microrods by a simple wet chemical method. Growth duration is found to play a crucial role in the morphologies of these ZnO nano/microcrystallites. In addition, growth conditions are systematically…
Soils are formed in a structural continuity of layers along a toposequence. The objective of this study was to characterize the chemical and physical properties of soils in two topossequences derived from basaltic rocks in the state of Parana, with different slopes, aiming to identify the relationships between their a…

Here we report on a spectro-chemical approach to investigate the adsorption of dissolved Cd ions to montmorillonite (M) in the presence of a mixed consortium of soil bacteria. Results indicate that the order of metal-loading was M- microbial complex > microbial biomass > M. Surface interactions of Cd with M-microbial…
Surface modification of γ-Fe2O3 nanoparticles synthesized by a chemically induced transition has been attempted by adding ZnCl2 during synthesis. The structure of the modified particles was studied using X-ray diffraction (XRD) and transmission electron microscopy (TEM). The experimental results showed that ZnFe2O4 gr…
The Directed Self Assembly (DSA) method is becoming a key complementary technology for enabling lithographic pattern feature shrinkage. Recent DSA technology has developed remarkable improvements in many aspects of materials and process. Block co-polymer, especially polystyrene-block-polymethylmethacrylate (PS-b-PMMA)…
Various kinds of Ag nanostructures were grown on various metallic substrates using hexakisphosphate (IP6) as a silver carrier agent. The Ag nanostructures with three-dimensional dendritic structure, the two-dimensional dendritic structure, the two-dimensional fractal structure, particles and nanowire structures were c…
Abstract This study is concerned with air oxidation of TiAlCr-Y coated Ti45Al-8Nb (at%) alloy between 750 °C–950 °C for 500 hours. It was shown in these tests that at 750 °C, 850 °C and 950 °C, the oxidation degradation increased with temperature: at 750 °C the oxide scale consisted of TiO2/Al2O3/Cr2O3 phases, whilst…
The aerogel-type wood is prepared under crafts of dissolution of wood materials by 1 - propenyl -3- methylimidazolium ionic liquid and followed supercritical drying process. And then, cellulose fibers as supporting frame with incomplete three-dimensional cross-linked network are reformed after dissolution of aerogel-b…
The transport properties of ZnO nanobelts along the (101¯0) non-polarized direction coupled with Cu electrodes were studied via non-equivalent Greens functions method and density functional theory formalism. The transport properties were greatly affected by interfacial spacing and nanobelt widths. The conductance decr…
Relative to the power grid, the short-capacity system has smaller inertia and weaker ability to bear disturbance. As a result, the synchronous generator in short-capacity system will be greatly influenced by harmonic. To reveal how harmonic influence the generator, this article analyzed how harmonic current will influ…
Synthesis of oxynitride solid solutions CaAl 4-x Si x O 7-x N x :Eu 2+ (x = 0 -4) was attempted by the solid state reaction (SSR) methods using Si 3 N 4 and AlN as nitrogen sources. The Ca 3 Al 8 Si 4 O 17 N 4 (x = 4/3) sample with the high phase purity was obtained when AlN was used as a nitrogen source whereas the s…
Dissolution testing has emerged in the pharmaceutical field as a very important tool to characterise the performance of drug products. Enrofloxacin is an antimicrobial frequently used in veterinary medicine that has no dissolution method described in pharmacopoeias. In vitro dissolution tests of enrofloxacin tablets w…
The photoluminescence (PL) spectrum of Si quantum rods (QRs) shows multiple peaks in the visible region. The PL decay is tri-exponential and decay time monotonically decreases with increasing emission energy. The multi-exponential nature of the PL emission indicates that the rediative recombination occurs through a di…
With different high pressure heat treatments on Cu–Al alloy, the effects on microstructure and thermal expansion coefficients of Cu–Al alloy are studied in the paper by optical microscopy, scanning electron microscopy, transmission electron microscopy and expansion instrument etc. The experimental results show that af…
