An iced lipid nanotube has been employed as a template to perform sol-gel transcription of transition metal alkoxides in the absence of solution catalysts, giving titania, tantalum oxide and vanadium oxide nanotubes in aqueous dispersions.
Polyimide nanotubes with tunable wall thickness were fabricated by a precursor impregnation method using an AAO template, and carbon nanotubes containing magnetic iron oxide were obtained using ferric chloride-embedded polyimide precursor by a carbonization process.
Dense (LSM) electrodes were patterned by photolithography and fabricated via pulsed-laser deposition on -stabalized (YSZ) electrolytes. Impedance analysis shows that the interfacial polarization resistance decreases significantly as electrode thickness drops below a critical value, beyond which the top surface of the…

One potentially significant challenge to the structural integrity of the reactor pressure vessel (RPV) in a pressurized water reactor (PWR) is posed by a PTS event wherein rapid cooling of the downcomer occurs, an event which may be followed by re-pressurization.The temperature drop produced by rapid depressurization…
The temperature dependence of emission spectrum of full-color emitting , is investigated. As an increase of temperature, three emission bands show anomalous blueshift along with broadening bandwidth and decreasing intensity. With increasing temperature, variations in both the peak position and the intensity-quenched t…
A linear dynamic model is established for two-strand or Sirospun yarn processing. Approximate oscillating frequencies in the vertical and horizontal directions are obtained. By suitable choice of certain processing parameters, the mixture construction after the convergence point can be optimally matched.
Size-controlled EuS nanoparticles were synthesized by the reaction of europium metal with thiourea as a sulfur source in liq. NH3, whose surface was confirmed to be modified with thiourea by FT-IR measurement, and the opto-magnetic properties (Faraday effect) of the EuS nanoparticles were investigated by using PMMA fi…
We show that polyelectrolyte shells may be perfect hosts and microreactors for catalysis. Using a layer-by-layer self-assembly process to form hollow polyelectrolyte capsules, we show that individual layers can be replaced by palladium and gold nanoclusters forming robust cell-type microcapsules. Testing the catalytic…
The kinetics of vanadate release from an organic coating and the stability and protective ability of the newly formed vanadate-based films on zinc surfaces have been studied with respect to self-healing ability of vanadate-pigmented organic coatings. The results were compared with those obtained with chromate. The kin…
Poly(3-hydroxybutyrate) (P3HB), its co-polymers with 3-hydroxyvalerate (HV) (PHBV8 and PHBV22), and their hydroxyapatite (HAp) containing composites (5 and 15%, w/w) were prepared by injection molding. PHBV bone plates with low valerate contents and 15% (w/w) HAp appear to have better mechanical properties than the ot…
The effect of PAMAM G3.5, PAMAM G4 and PAMAM-OH G4 dendrimers on human and bovine serum albumins has been studied by fluorescence spectroscopy at different pH and ionic strength. It has been shown that the interactions between dendrimers and proteins depend on pH and the efficiency of interactions can be regulated by…
Oblique orientated alpha-helices are highly specialised protein structural elements that penetrate membranes at a shallow angle and are used to promote membrane destabilisation by a number of protein classes. Here, the use of extended hydrophobic moment methodology shows that the amphibian extrudates, aurein 1.2 and c…
In this work, the dielectric constant of rubidium manganese hexacyanoferrate was observed in the ultraviolet, visible, and near-infrared regions using spectroscopic ellipsometry (SE). The SE data for ε drastically varied with the phase transition between the high-temperature and low-temperature phases, e.g., the gain…
Solid Oxide Fuel Cell (SOFC) developers are presently considering both internal and external reforming fuel cell designs. Generally, the endothermic reforming reaction and excess air through the cathode provide the cooling needed to remove waste heat from the fuel cell. Current information suggests that external refor…
Yttria-stabilized zirconia ͑YSZ͒ electrolyte disks with patterned platinum ͑Pt͒ electrodes having different three phase boundary ͑TPB͒ lengths ͑l TPB ͒, but the same electrode-electrolyte interface area, were deposited on one of the two faces using photomicrolithography.Platinum counter electrode was applied on the ot…
Novel micro-capsules (carbon nanotubosomes) have been fabricated by cross-linking shells of amine-functionalized multi-walled carbon nanotubes (MWNTs) produced by their adsorption on water-in-oil emulsion drops followed by an emulsion-inversion.
The step-wise assembly of the high nuclearity cluster, {[Ni(II)(H2O)5]6[Co(III)(tmphen)2]3[Fe(II)(CN)6]2}13+, is achieved by treating {[Co(tmphen)2]3[Fe(CN)6]2} with six equivalents of Ni(ClO4)2 in aqueous MeOH.
The majority of drug products are solid dosage forms, most of which contain the drug substance in the crystalline state. This review considers the forces responsible for crystal packing, the various types of pharmaceutical crystals, and the methods used to determine the structure of pharmaceutical crystals. These topi…
Epiclon [3a,4,5,7a-tetrahydro-7-methyl-5-(tetrahydro-2,5-dioxo-3-furanyl)-1,3-isobenzofurandione] (1) was reacted with L-methionine (2) in acetic acid and the resulting imide-acid 3 was obtained in high yield. The diacid chloride 4 was prepared from diacid derivative 3 by reaction with thionyl chloride. Thermostable p…
