Redox Properties of Self-Assembled Gold Nanoclusters

The redox properties of a monolayer of alkanethiolate-protected gold nanoclusters (MPCs) constructed on a gold slide electrode was studied in 1,2-dichloroethane (DCE) electrolyte solutions. The influence of the electrostatic interaction between attached MP ...

Adsorption and photoreactivity of CdSe nanoparticles at liquid|liquid interfaces

Hubert Girault, Bin Su, Jean-Pierre Abid, Nicolas Eugster

The voltage induced assembly and photoreactivity of cadmium selenide (CdSe) nanoparticles protected by mercaptosuccinic acid are studied at the polarisable interface between water and 1,2-dichloroethane electrolyte solutions. Cyclic voltammograms and admit ...

A generalised model for dynamic photocurrent responses at dye-sensitised liquid|liquid interfaces

Hubert Girault, Nicolas Eugster, Zdenek Samec

The heterogeneous photoinduced electron transfer involving dyes adsorbed at the interface between two immiscible electrolyte solutions and redox molecules located in the adjacent phase manifests itself as photocurrent responses under potentiostatic conditi ...

Absolute Standard Redox Potential of Monolayer-Protected Gold Nanoclusters

Hubert Girault, Bin Su

The redox properties of monolayer-protected gold nanoclusters (MPCs) are considered from both the theoretical and experimental viewpoints. The “absolute standard redox potential” ([ ]abs) of MPCs is first derived from electrostatic considerations. A linear ...

Synthesis of novel cyanine-fullerene dyads for photovoltaic devices

Frank Nüesch, Libero Zuppiroli

Two novel cyanine-fullerene dyads have been synthesized by means of the Prato reaction from the corresponding cyanine-aldehyde, N-methylglycine and C60. As well as a thorough characterization using MS-TOF, 1H-NMR, 13C-NMR a ...

Conducting Polymers Containing In-Chain Metal Centers: Electropolymerization of Oligothienyl-Substituted {M(tpy)2} Complexes and in Situ Conductivity Studies, M = Os(II), Ru(II)

Ulf Anders Hagfeldt

The electropolymn. of Ru and Os bis-terpyridine complexes that form rodlike polymers with bithienyl, quaterthienyl, or hexathienyl bridges were studied. Absorption spectroscopy, SEM, and cyclic voltammetry were used to characterize the monomers and resulti ...

Ag+ transfer across the water|1,2-dichloroethane interface facilitated by complex formation with tetraphenylborate derivatives

Hubert Girault, Carlos Manuel De Melo Pereira, Laure Tomaszewski

The assisted transfer of silver ion, Ag+, by complexation of Ag+ with the tetrakis(4-chlorophenyl)borate (TPBCl−) anion was studied at the interface between two immiscible electrolyte solutions (ITIES). The elucidation of the interfacial mechanisms employe ...

Effect of the Phase Volume Ratio on the Potential of a Liquid-Membrane Ion-Selective Electrode

Hubert Girault, Zdenek Samec

Two-phase liquid system IA(w)jIX(o) comprising the interface between the aqueous solution (w) of uni-univalent electrolyte IA and an organic solvent solution (o) of a uni-univalent electrolyte IX with the common cation I+ is considered as a simple model of ...

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 ...

Hydrovoltaic cells. Part II: Thermogalvanic cells and numerical simulations of thermal diffusion potentials

Hubert Girault, Valérie Devaud

When two electrolyte solutions of different temperature are placed in contact, a thermal diffusion potential (TDP) is established. The phenomenon is studied numerically using finite element simulations of the temperature distribution within a hydrodynamic ...
