Metal dusting is a severe form of corrosive degradation of metals and alloys at high temperatures (350-950°C) in carbon-supersaturated gaseous environments. Fe, Ni, and Co, as well as alloys based on these metals are all susceptible. The corrosion manifests itself as a break-up of bulk metal to metal powder, hence, th…
The metal-metal bonded indium porphyrin-osmium cluster complex [(TPP)InOs3(mu-H)2(CO)9(mu-eta2-C5H4N)] was first synthesized and characterized using the indium porphyrin hydride as the precursor. The complex has very good optical limiting performance with determined optical limiting threshold of 0.4 J cm(-2).
The octahedral complexes cis- and trans-[Ru(CN)2(CNtBu)4] are prepared in quantitative yields from the reaction of Ru3(CO)12 with an excess of the isocyanide and under CO pressure. During the reaction, part of the isocyanide ligands are reductively cleaved to yield the cyanide ligands, isobutene and hydrogen. The latt…
Ultra-low carbon IF steel was deformed to various strains ranging from 0.8 to 5.6 by the accumulative roll-bonding (ARB) process at 500°C, and subsequently annealed at various temperatures for 1.8 ks in order to clarify the effect of strain on the microstructures and mechanical properties. The materials deformed by re…
The advancement of efficient hybrid fuel cell systems requires the evolution of analysis strategies for evaluating and developing cycle design. This paper addresses the performance of a recently developed simulation tool for the analysis of tubular SOFC power systems as compared to observed hybrid operation data. Desc…
High Capacitance EDLC Using a Carbon Material Obtained by Carbonization of PVDC : The Effect of the Crystallite Size of the Pristine PVDC , Endo, M., Kim, Y. J., Osawa, K., Ishii, K., Inoue, T., Nomura, T., Miyashita, N., Dresselhaus, M. S.
A comparative study was carried out on the fabrication and performance of Ni/3 mol % (Ni/TZ3Y) and Ni/8 mol % (Ni/TZ8Y) cermet anodes. The electrochemical performance of Ni/TZ3Y and Ni/TZ8Y cermet anodes was investigated in relation to the fabrication processes such as the coarsening treatment of zirconia and Ni/zirco…
Abstract A new class of thermosetting resins has been developed that is based on the cationic copolymerization of regular soybean oil (SOY), low saturation soybean oil (LSS), or conjugated LSS (CLS) with various alkene comonomers initiated by boron trifluoride diethyl etherate (BFE) or related modified initiators. The…
Quantitative aspects for electrochemical preparation and subsequent characterization of a functional polymer, poly(1,5-diaminonaphthalene), have been studied using electrochemical quartz crystal microbalance experiments along with transient electrochemical experiments, and the results are reported. The polymer was pre…
Sorption of acetates and nitrates of mercury, lead, silver and bismuth from acetate buffers or nitric acid solutions by three types of neutral hypercrosslinked polystyrene materials has been studied. The sorbents were prepared by crosslinking either linear polystyrene or a styrene-0.7% DVB copolymer with monochlorodim…
Heating [Mn3O(O2CPh)6(py)2(H2O)] in MeCN at 100 degrees C for 12 hours in a sealed Teflon container produces the hexanuclear species [Mn6O2(O2CPh)12(py)2]: dimerisation of the triangle occurs via solvent loss and ligand rearrangement.
The ability to control reductions in the saturation energy density is important from the point of view of realizing applications where one would require successive layers in the practical limiter to be fabricated from materials of decreasing saturation energy density. In this paper, two new axially aryloxy substituted…
Copper exchanged on beta zeolites are extremely active and selective for the catalytic oxidation of ammonia to nitrogen and water and this activity correlates to the ease of reduction of the copper species.
Bulk hydrogen retention and hydrogen diffusion in graphite and carbon materials have been studied to estimate hydrogen recycling and tritium inventory in a fusion reactor environment. Hydrogen may permeate into a filler grain in the form of a hydrogen molecule, diffuse through crystallite boundaries and finally be tra…
The effect of the organophilisation of a Na-bentonite, through cationic exchange reaction with a commercial quaternary benzalkonium salt, on the morphology and mechanical behaviour of polypropylene (PP)/low density polyethylene (LDPE) blend matrices has been investigated employing a statistical experimental design. Th…
A first study by in situ FTIR spectroelectrochemistry of TTF and TTM-TTF has been undertaken. The oxidation, in this case, is caused only by electrochemistry, which constitutes a clear advantage over chemical oxidation since no side products are present in the solution. In this context, we obtained the signals of neut…
Intratumour heterogeneity in the uptake of blood-borne technetium-labelled human serum albumin ((99m)Tc-HSA) was studied in human melanoma xenografts in an attempt to identify transport barriers leading to inadequate and heterogeneous uptake of macromolecular therapeutic agents in tumours. The Bioscope imaging system,…
Two series of unsymmetrical diphenyl-1,3-diketones, each species bearing one terminal alkene, have been synthesized. These diketones have been converted into their respective unsymmetrical diphenylisoxazoles [3(5)-(4-ω-alkenyloxyphenyl)-5(3)-(4-alkoxyphenyl)isoxazoles] which have been isolated as equal mixtures of two…
Ceria and doped ceria nanopowders synthesized in flames from submicrometer-sized droplets of precursor solutions demonstrate several characteristics that promise superior performance when used to fabricate electrolytes for solid oxide fuel cells relative to powders synthesized using other technologies. Combustion chem…
