This paper describes a case study of two electrolysis tests of solid oxide cells ͓Ni/yttria-stabilized zirconia ͑YSZ͒-YSZ-lanthanum strontium manganite ͑LSM͒/YSZ͔ tested in a plug-flow setup.An extensively instrumented cell test setup was used, and the tests involved measurements of the cell impedance at open-circuit…
Red-shifted photoluminescence is observed in the co-crystal of arene- and perfluoroarene-attached bipyridines, which is a perfectly layered array through arene–perfluoroarene interactions.
We present a convenient method to prepare fluorophores 3- or 3,7-divinyl substituted 10H-phenothiazines and their protonation forms can aggregate to become fluorescent organic nanoparticles (FONs) with bright fluorescent spots in the lysosomes of cancer cells but not normal cells.
A new surface-tethered iterative carbohydrate synthesis (STICS) technology is presented in which a surface functionalized 'stick' made of chemically stable high surface area porous gold allows one to perform cost efficient and simple synthesis of oligosaccharide chains; at the end of the synthesis, the oligosaccharide…
The surface morphology, electrochemical characteristics, and salt spray corrosion performance were studied for cerium-based conversion coatings on Al 2024-T3 that were post-treated in heated aqueous solutions of orthophosphate, pyrophosphate, and polyphosphate compounds. Phosphate post-treatment reduced cracking in th…
Corrosion tests of ferritic/martensitic (F/M), austenitic stainless and Si-added austenitic steels were conducted at 450 to 600°C for 2000 h or 3000 h in oxygen-saturated lead-bismuth eutectic (LBE) to clarify temperature effect on corrosion behavior. While the corrosion depth is small at 450°C because of oxide film f…
We construct simple models to compare ordered tricontinuous patterns that are topologically consistent with the constraints imposed by three-arm star polyphile self-assembly, analogous to steric packing and elastic bending models used to analyse bicontinuous mesophases in amphiphilic assemblies. We find a number of co…
Biodegradable amino-acid-based poly(ester amide) (PEA) ultra-fine fibers pre-loaded with a nitroxyl radical model compound, 4-amino-2.2.6.6-tetramethylpiperidine-1-oxy (4-amino-TEMPO), were prepared by electrospinning. The fiber size and morphology were shown to be greatly affected by the composition ratio of the solv…
We study the equilibrium morphology of droplets of symmetric AB diblock copolymer on a flat substrate. Using self-consistent field theory (SCFT), we provide the first predictions for the equilibrium droplet shape and its internal structure. When the substrate affinity for the A component, ηA, is small, the droplet ado…
In this paper two ultra high speed carbon nanotube Full-Adder cells are presented. First design uses two transistors, two resistors and seven capacitors and the second one uses four transistors and seven capacitors. The first design is faster and the second one consumes less power. Simulation results illustrate signif…
New hybrid organic/inorganic magnets have been synthesized by insertion of stilbazolium-carboxylate and/or -sulfonate dyes into cobalt and copper layered hydroxides. Co2(OH)3.57(MR)0.43·1.88 H2O (MR⊂Co (1)) (MRNa: Methyl Red sodium salt: sodium 2-[4-(Dimethylamino)phenylazo]benzoate), Co2(OH)3.27(MO)0.73·2.94 H2O (MO⊂…
Fluorescent nanoparticles of zirconia doped with europium (ZrO2:Eu3+) have been produced via the co-precipitation of simple metal salt precursors using continuous supercritical water hydrothermal synthesis. The effect of reaction temperature and residence time on both particle size and conversion were investigated. In…
Advances in nanotechnology research have led to the creation of new generation of contrast agents, therapeutics, and delivery systems. These applications are expected to significantly improve the diagnosis and treatment of a variety of diseases. Two nanotechnologies-semiconductor and metallic nanostructures-are the mo…
The employment of the anion of methyl 2-pyridyl ketone oxime (mpko(-)) as a tridentate chelating/bridging ligand in manganese chemistry is described. The inorganic anion (Br(-), ClO(4)(-)) used in the reaction affects the identity of the product. The reaction of MnBr(2) and one equivalent of mpkoH in the presence of a…
From 2.10.08 to 12.10.08 an intense bloom of Noctiluca scintillans (Macartney) was observed for the first time in the coastal areas of Gulf of Mannar (southeast coast of India) near Appa Island, Thalaiyari Island and Valai Island and subsequently it intensified into a dense bloom in Muthupettai area and spread from Ki…
Macroporous SiC ceramics were obtained from porous phenyl-bridged polysilsesquioxane prepared by a sol–gel method accompanied by spinodal decomposition subsequently subjected to intramolecular carbothermal reduction. By this method, we can obtain macroporous SiC ceramics with improved atomic-level homogeneity and cont…
Iridium-based stellate (star-shaped) polyhedral oligomeric silsesquioxane macromolecular dyes were synthesized and an inkjet printing process to deposit inks based on these materials was developed. Polymeric–macromolecular blended light emitting diodes based on these hybrid organic–inorganic dyes were studied. We find…
The significant factor that determines the improvement of properties in rubber by the incorporation of nanoclay is its distribution in the rubber matrix. The simple mixing of nonpolar rubber and organically modified nanoclay will not contribute for the good dispersion of nanofiller in the rubbery matrix. Hence a polar…
A series of composite films were prepared by blending chitosan with three polycations, poly(L-lysine), polyethyleneimine, and poly-L-ornithine, in specific blend proportions. The surface properties of the composite films, including surface topography, chemistry, and wettability, were examined by atomic force microscop…
A wind turbine blade generally consists of two shells which are bonded together with a structural adhesive. K.P. Subrahmanian and Fabrice Dubouloz of Huntsman Advanced Materials discuss the requirements for the adhesives used and the development of a product with improved toughness.
