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 ...

Pièce en céramique pigmentée

Heinrich Hofmann, Alke Fink

NOVELTY - The component partially or wholly comprises pigmented ceramic. The pigment comprises nanoparticles of metal of group IB in periodic table, alkaline metals or their alloy, coated with a layer of silica such as crystalline silica. The crystalline s ...

Preparation of gold nanoparticles by heat treatment of sputter deposited gold on boron-doped diamond film electrode

Christos Comninellis, György Foti, Bahaa El Roustom

A novel two-step method was developed to prep. gold nanoparticles on boron-doped diamond (BDD) electrode. It consisted of sputter deposition of max. 15 equiv monolayers of gold, followed by a heat treatment at 400-600 Deg in air. The as-sputtered gold depo ...

Development of an electroless post-processing technique for depositing gold as electrode material on CMOS devices

Nico de Rooij, Peter Van der Wal

The limited electrode density and thus, the limited spatial resolution of substrate-integrated microelectrodes arrays (MEAs) used in in-vitro electrophysiology are currently considered as the main constraints of this technique. By taking advantage of the c ...

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 ...

Micromechanical relay with electrostatic actuation and metallic contacts

Nico de Rooij

In this paper, an improved design of an electrostatic polysilicon microrelay with metallic contacts is presented. The polysilicon layer is used for the actuator while the nickel and gold layers are used for the contacts. Improved contact resistance is demo ...

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
