The influence of catalyst support alumina-silica in terms of different Al2O3 to SiO2 mole ratios containing 20 wt.% Ni on the production of hydrogen and catalyst coke formation from the pyrolysis-catalysis of waste tyres is reported. A two-stage reactor system was used with pyrolysis of the tyres followed by catalytic reaction. There was only a small difference in the total gas yield and hydrog...

These are model studies whose aim is to obtain information that would allow development of new technology for synthesizing monolayers of Al2O3-C with adjusted microstructure on cemented carbides. The Al2O3-C layer will constitute an intermediate layer on which the outer layer of Al2O3 without carbon is synthesized. The purpose of the intermediate layer is to block the cobalt diffusion to the sy...

in addition to its antioxidant effect, vitamin e or α–tocopherol is suggested to enhance remyelination in the animal model of non-inflammatory demyelination. in this study, the possible proliferative effect of vitamin e on human- induced pluripotent stem cell-derived neural progenitors (hips-nps) and the underlying mechanisms were investigated in vitro. nps were induced from ips cells via 3 ste...

Pd nanoparticles (PdNPs) stabilized by methyl cellulose (MC) were synthesized in an aqueous solution, which are monodispersed nanoparticles. PdNPs/α-Al2O3 catalyst was prepared with monodispersed PdNPs and showed better catalytic performance than Pd/α-Al2O3 catalyst prepared by the incipient wetness impregnation method using Pd(NO3)2 as a precursor. The catalysts were characterized by transmiss...

Al2O3–Ta2O5 nanolaminate films were prepared via atomic layer deposition (ALD) on silicon with a single overall composition and thickness, but with a varying number of Al2O3/Ta2O5 bilayers. The composition of the films was roughly 57% Al2O3 and 43% Ta2O5 and the total film thickness was held at 58 nm, while the number of bilayers was varied from 3 to 192 by changing the target bilayer thickness...

In a common salt-in-polymer electrolyte, a polymer which has polar groups in the molecular chain is necessary because the polar groups dissolve lithium salt and coordinate cations. Based on the above point of view, polystyrene [PS] that has nonpolar groups is not suitable for the polymer matrix. However, in this PS-based composite polymer-in-salt system, the transport of cations is not by segme...

Tetraplatinum cluster complexes bearing hydrophilic anchors, [Pt4(μ-OCOCH3)4(μ-OCOC6H4OH-4)4] (2a), [Pt4(μ-OCOCH3)4(μ-OCOC6H4B(OH)2-4)4] (2b), and [Pt4(μ-OCOCH3)4(μ-OCOC6H4NH2-4)4] (2c), were successfully prepared by a selective substitution reaction of four in-plane acetates of [Pt4(μ-OCOCH3)8] (1) with the corresponding p-substituted benzoic acids. Solid-state structure determination of 2a re...

The plasma spray technique has been used by several researchers to deposit nanostructured ceramic coatings, but there is no available literature discussing how to fabricate a bulk, freestanding nanostructured component by such a technique. In the current study, net shape nanostructured Al2O3 structures have been fabricated using the plasma spray technique. A detailed characterization of the spr...

Nanowire nanoelectronic devices have been exploited as highly sensitive subcellular resolution detectors for recording extracellular and intracellular signals from cells, as well as from natural and engineered/cyborg tissues, and in this capacity open many opportunities for fundamental biological research and biomedical applications. Here we demonstrate the capability to take full advantage of ...

Development of effective electrical magnetohydrodynamic (MHD) coating insulating induced current path is one of key fusion technologies for fusion blanket research and development. Electrical insulation coating is extremely important for lead lithium (PbLi) MHD thermofluid study from pointview of secure electric insulating wall condition. The alumina (Al2O3) coatings fabricated by a sol-gel met...
