Polyoxometalates and colloidal nanocrystals as building blocks for metal oxide nanocomposite films

The authors report the prepn. of soln.-derived metal oxide nanocomposite films by combining polyoxometalates (POMs) and colloidal oxide nanocrystals. Polyniobates and vanadates were combined with Sn-doped In2O3 (ITO) nanocrystals leading to Nb2O5-ITO, V2O5 ...

Films of brookite TiO2 nanorods/nanoparticles deposited by matrix-assisted pulsed laser evaporation as NO2 gas-sensing layers

Raffaella Buonsanti, Mikaël Martino

TiO2 nanorods in the brookite phase, with av. dimensions of 3-4 nm × 20-50 nm, were synthesized by a wet-chem. aminolysis route and used as precursors for thin films that were deposited by the matrix-assisted pulsed laser evapn. (MAPLE) technique. A nanoro ...

Fabrication of Functional Silicon Surfaces using Metallic Nanostructures Produced by Block Copolymer Self-Assembly

Li Wang

Self-assembly is the autonomous organization of components into patterns or structures without human intervention. At the molecular level, self-assembly usually involves non-covalent interactions of various natures, such as van der Waals, electrostatic and ...

Application of an asymmetric flow field flow fractionation (AF4) multi-detector approach for metallic ENP characterization - prospects and limitations demonstrated on Au nanoparticles

Christian Ludwig, Andrea Ulrich, Harald Hagendorfer

In this work we discuss about the method development, applicability and limitations of an asymmetric flow field flow fractionation (A4F) system in combination with a multi-detector setup consisting of UV/vis, light scattering, and inductively coupled plasm ...

Influence of Y2O3 and Fe2Y additions on the formation of nano-scale oxide particles and the mechanical properties of an ODS RAF steel

Nadine Baluc, Zbigniew Oksiuta

The main goal of this work was to manufacture an oxide dispersion strengthened (ODS) reduced activation ferritic steel from a pre-alloyed, gas atomised Fe-14Cr-2W-0.2Ti (in wt.%) powder mechanically alloyed with either 0.3%Y2O(3) or 0.5%Fe2Y particles and ...

New Analytical Methods for Size Fractionated, Quantitative, and Element Specific Analysis of Metallic Engineered Nanoparticles in Aerosols and Dispersions

Harald Hagendorfer

The application of engineered nanoparticles (ENP) increased almost exponentially during the last decade. Next to carbon based ENP, metal based ENP are the next most commonly employed. Utilization of such particles for medical applications, remediation of t ...

Engineering light absorption in single-nanowire solar cells with metal nanoparticles

Anna Fontcuberta i Morral, Carlo Colombo

Semiconductor nanowires (NWs) possess a fascinating ability to efficiently collect and trap light into a sub-wavelength volume due to the occurrence of leaky mode resonances. The same confinement ability is manifested by metal nanostructures thanks to the ...

Processing of yttria stabilized zirconia reinforced with multi-walled carbon nanotubes with attractive mechanical properties

Daniele Mari, Robert Schaller, Mehdi Mazaheri, Gilbert Fantozzi

The improvement of the mechanical properties of carbon nanotube reinforced polycrystalline yttria-stabilized zirconia (CNT-YSZ) was questionable in earlier investigations due to several difficulties for processing of these composites. In the present articl ...

Supported nitrogen-modified Pd nanoparticles for the selective hydrogenation of 1-hexyne

Paul Joseph Dyson, Lioubov Kiwi, Gabor Laurenczy, Rocio Micaela Crespo Quesada, Ryan Dykeman

2,2′-Bipyridine (bipy) and an imidazolium-functionalized bipy ligand were used in the synthesis of palladium nanoparticles in water and in ionic liquid. The function of such ligands was twofold: first, as stabilizing agents to prevent the agglomeration of ...
