Gold Metal Liquid-Like Droplets

Hubert Girault, Pierre-François Marie Brevet, Manuel Alejandro Méndez Agudelo, Heron Vrubel, Micheal Diarmaid Scanlon, Dmitry Momotenko, Evgeny Smirnov

Simple methods to self-assemble coatings and films encompassing nanoparticles are highly desirable in many practical scenarios, yet scarcely any examples of simple, robust approaches to coat macroscopic droplets with continuous, thick (multilayer), reflect ...

A new target for gold(I) compounds: glutathione-S.transferase inhibition by auranofin

Paul Joseph Dyson, Christian Hartinger, Angela Casini

Nowadays, gold compounds occupy a relevant position constituting a promising class of experimental anticancer metallodrugs. Several research efforts have been devoted to the investigations of the pharmacological properties of gold(I) complexes bearing phos ...

In-Plane Fabricated Insulated Gold-Tip Probe For Electrochemical And Molecular Experiments

Nico de Rooij, Terunobu Akiyama, Sebastian Gautsch, Peter Van der Wal, Yexian Wu

In this contribution we present a scanning probe with a gold-tip completely encapsulated with insulator all the way to the apex. The probe fabrication is unique owing to an in-plane arrangement in which the width of the cantilever is defined by deep reacti ...

Biosensor based on chemically-designed anchorable cytochrome c for the detection of H2O2 released by aquaticcells

Olivier Martin, Christian Santschi, Guillaume Suarez

A novel third generation biosensor was developed based on one-shot adsorption of chemically-modified cytochrome c (cyt c) onto bare gold electrodes. In contrast to the classic approach which consists of attaching cyt c onto an active self-assembled monolay ...

Application of a Versatile Nanoparticle Stabilizer in Phase Transfer and Catalysis

Paul Joseph Dyson, Vincent Laporte, Ilaria Biondi

Gold and rhodium nanoparticles stabilized by a cationic polymer can be readily modified by anion exchange to afford nanoparticles that may be dispersed in a wide range of organic solvents and ionic liquids. The catalytic activity of the Rh nanoparticle dis ...

Ethynyl Benziodoxolones for the Direct Alkynylation of Heterocycles: Structural Requirement, Improved Procedure for Pyrroles, and Insights into the Mechanism

Rosario Scopelliti, Jérôme Waser, Jonathan Brand

This report describes a full study of the gold-catalyzed direct alkynylation of indoles, pyrroles, and thiophenes using alkynyl hypervalent iodine reagents, especially the study of the structural requirements of alkynyl benziodoxolones for an efficient ace ...

Influence of gold particle size on the photocatalytic activity for acetone oxidation of Au/TiO2 catalysts prepared by dc-magnetron sputtering

Francis Lévy

Two series of Au/TiO2 materials with different gold content have been prepared by dc-magnetron sputtering on ceramic shaped pure anatase or Degussa P25 TiO2. The time of deposition was varied between 1 and 20 min in order to obtain different thickness and ...

Mechanistic studies on two dinuclear organogold(III) compounds showing appreciable antiproliferative properties and a high redox stability

Angela Casini

Two dinuclear oxo-bridged organogold(III) compounds, namely [(N,N,C)(2)Au-2(mu-O)]PF6 (with N,N,CH = 6-(1-methylbenzyl)-2,2'-bipyridine, Au(2)O1; or 6-(1,1-dimethylbenzyl)-2,2'-bipyridine, Au(2)O2), were previously prepared and characterised. Their so ...

Intergranular penetration of liquid gold into stainless steel

Michel Rappaz, Denis Favez, Léa Deillon, Jean-Daniel Wagnière

Intergranular penetration of liquid 18 K gold into a superaustenitic stainless steel, which occurs during laser welding of these two materials, has been studied using a C-ring device which can be put under tensile stresses by a screw. It is shown that liqu ...

Polymer Brush Guided Formation of Thin Gold and Palladium/Gold Bimetallic Films

Harm-Anton Klok, Dusko Paripovic

This manuscript reports a new strategy to guide the chemical solution deposition of thin, microstructured metal films. The proposed strategy is based on the use of poly(2-(methacryloyloxy)ethyl ammonium chloride) (PMETAC) brushes grown via surface-initiate ...
