Properties of xYSZ nanoparticles and pellets with x varying from 1 to 15%

Suciu C., Dorolti E., Hoffmann A.C., University of Bergen, NO

Nanoparticles of oxides are used, among other things, for solid oxide fuel cells (SOFCs), where the use of yttria-stabilized zirconina nanoparticles in the inner region of the anode will increase the extent of the "triple-phase [...]

Multifunctional Nanostructures and Nanoarchitectures

Hunyadi Murph S.E., Savannah River National Laboratory, US

The development of functional nanomaterials with multi-detection modalities opens up new avenues for creating multi-purpose technologies for many applications. The “ideal” nanoparticle would combine multiple detection modalities (magnetic, plasmonic, elastic or inelastic light scattering, fluorescence, [...]

Effect of flame-made metal (M = Pt, Nb, Ru) -loaded In2O3 on NO2 gas sensing

Phanichphant S., Chiang Mai University, TH

Unloaded In2O3 and M-loaded (M = Pt, Nb and Ru) In2O3 nanoparticles loaded with 0.25–1.00wt% metal were successfully synthesized in a single step by the flame spray pyrolysis (FSP) technique. Unloaded In2O3 and M-loaded (M [...]

Development of a Platinum Nanoparticle based Microcombustor Power Device

Bakrania S., Rowan University, US

Microcombustors coupled with thermoelectric devices have the potential to provide a prolonged power source for portable devices as opposed to conventional batteries due to significantly higher energy densities. Recharging then can be easily achieved by [...]

Polymer Nanofluid for enhanced oil recovery: A design of polystyrene nanoparticles, transport behavior evaluation and unconsolidated flooding test

de Araujo L.L.G.C., de Avila J.N.L., de Araujo L.L.G.C., de Avila J.N.L., Drexler S., Rodrigues Jr. J.A., Nascimento R.S.V., UFRJ, BR

This work focuses on the design of a nanoparticle containing polymer and surfactant containing that would be used in solution as a nanofluid for enhanced oil recovery. The nanoparticle is formed by crosslinking chemical reactions [...]

A highly dispersed Cu-Ni/Ce0.5Zr0.5O2/SBA-15 nanocatalysts: Preparation, characterization and the catalytic application in direct synthesis of dimethyl carbonate

Yang M., Zhang Z-q, Chang Q-Q, Liu E-Z, Liu Y., Zhao B., Liu E-Z, Liu Y., Hu X.Y., Fan J., Northwest University, CN

SBA-15 has been successfully applied as a support to prepare supported metal catalysts[1]. Nevertheless, Conventional impregnation method cannot assure the incorporation of active species into SBA-15 mesopores. The modification of silica support using ethylene glycol [...]

Nanogenotoxicity Measurements of Oxidative DNA Damage Using Isotope Dilution Mass Spectrometry

Petersen E., Jaruga P., Dizdaroglu M., Nelson B., National Institute of Standards and Technology, US

Hyphenated mass spectrometry (gas chromatography/mass spectrometry) techniques have been employed as one of the primary analytical tools for investigating the effects of ionizing radiation, chemical/biological carcinogens and oxygen derived free radicals on the induction and [...]

Synthesis and evaluation of T85-LPEI copolymers for pDNA delivery

Wang M.X., Carolinas Medical Center, US

In this study, a series of low molecular weight PEI (LPEI) modified with Tween 85 were prepared by varying feed ratio and PEI size (Mw: 0.8k, 1.2k and 2.0k Da) for gene delivery. The Mws [...]

Evaluation of the Potential Synergistic Antimicrobial Effects Observed using Various Combinations of Chemical Agents (Nanoparticled and Non-Nanoparticled) on a Selected Panel of Cheese Derived Microorganisms

O’ Callaghan K.A.M., Kerry J.P., University College Cork, IE

The aim of the this study was to examine the antimicrobial effectiveness of a number of agents (nanoparticled and non-nanoparticled) applied individually and in combination to cheese derived cultures to determine their suitably as active [...]
