Controlled Polyelectrolyte Coating of Glass-Supported Metal Nanostructures

Noelia Laura Bocchio

We investigated the coating of glass-supported gold nanostructures with polyelectrolyte multilayers. To achieve selective coating of either the metal or the glass, thiol and silane monolayers with different functionalities were used. Self-assembled monolay ...

Gold Nanoparticles Supported on Passivated Silica: Access to an Efficient Aerobic Epoxidation Catalyst and the Intrinsic Oxidation Activity of Gold

David Lyndon Emsley, David Benjamin Roger Antoine Gajan

Well-defined and perfectly dispersed [(square SiO)Au(1)] surface species supported on silica have been obtained via surface organometallic chemistry and transformed upon mild reduction (H(2), 300 degrees C) into small (1.8 +/- 0.6 nm) Au particles supporte ...

Resistivity Measurements of Gold Wires Fabricated by Stencil Lithography on Flexible Polymer Substrates

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Andreea Veronica Savu, Marc Antonius Friedrich van den Boogaart, Oscar Vazquez Mena, Katrin Sidler Arnet

We report on the patterning and characterization of titanium–gold (Ti–Au) wire test structures on polyethylene naphthalate (PEN), polyethylene terephthalate (PET) and polyimide (PI) substrates. PEN, PET and PI are flexible polymers which can withstand stre ...

Capteurs solaires colorés et intégration architecturale

Christian Roecker, Maria Cristina Munari Probst

L’utilisation de capteurs thermiques en façade reste très limitée, malgré le fait que les produits actuels soient performants et économiquement rentables dans la plupart des cas. L’une des raisons majeures de cette situation tient à la difficulté d’intégre ...

Focused electron beam induced deposition of gold

Elyahou Kapon, Patrik Willi Hoffmann, Benjamin Dwir, Ivo Utke, Klaus Leifer

Codeposition of hydrocarbons is a severe problem during focused electron beam writing of pure metal nanostructures. When using organometallic precursors, a low metal content carbonaceous matrix embedding and separating numerous nanosized metal clusters is ...

Mineralization of gold in block copolymer micelles

Harm-Anton Klok

Ultrasmall gold particles have been prepared inside the micelles of polystyrene-block-poly(ethylene oxide) and polystyrene-block-poly(2-vinylpyridine) in toluene. Starting point was the formation of a thermodynamically stable dispersion of HAuCl4
