Electron spin lifetime in chemically synthesized graphene sheets

László Forró, Bálint Náfrádi

Graphene is theoretically expected to be a highly suitable material for spintronic and quantum computation applications. Current experimental reports assign surprisingly low spin lifetimes to graphene and related carbon structures. Recently, we showed a so ...

Revealing and Accelerating Slow Electron Transport in Amorphous Molybdenum Sulphide Particles for Hydrogen Evolution Reaction

Michael Graetzel, Xile Hu, Thomas Moehl, Heron Vrubel

Electrochemical impedance spectroscopy is used to identify a slow electron transport process in hydrogen evolution catalysed by amorphous molybdenum sulphides on glassy carbon. A new chemical synthesis leads to an amorphous molybdenum sulfide catalyst with ...

A selective chemiluminescence detection method for reactive oxygen species involved in oxygen reduction reaction on electrocatalytic materials

Christos Comninellis, Pauline Bornoz

An original selective and quantitative detection method for direct access to reactive oxygen species (ROS) generated in near-neutral aqueous solutions during transient electrochemical experiments is described herein. Several chemiluminescent probes, which ...

Dielectrophoresis of lambda-DNA using 3D carbon electrodes

Philippe Renaud, Rodrigo Martinez Duarte

Carbon electrodes have recently been introduced as an alternative to metal electrodes and insulator structures for dielectrophoretic applications. Here, an experimental and theoretical study employing an array of 3D carbon electrodes contained in a microfl ...

Carbon-graphene nanocomposite cathodes for improved Co(II/III) mediated dye-sensitized solar cells

Michael Graetzel, Jun Ho Yum, Morgan Mertens Stefik, Yelin Hu

Cobalt-based electrolytes have significantly advanced the tunability and performance of dye-sensitized solar cells. The typically used platinum cathodes are expensive and non-optimal for cobalt complexes, motivating the search for replacements. Graphene na ...

Comparative study of three lactate oxidases from Aerococcus viridans for biosensing applications

Giovanni De Micheli, Sandro Carrara, Irene Taurino

A comparison between engineered and commercially available L-lactate oxidases from Aerococcus viridans was conducted for biosensing applications. Enzymes were adsorbed onto the surfaces of graphite electrodes modified with multi-walled carbon nanotubes. Th ...

Low Temperature Ferromagnetism in Chemically Ordered FeRh Nanocrystals

Harald Brune, Stefano Rusponi, Jan Gui-Hyon Dreiser, Sergio Vlaic, Alberto Cavallin

In sharp contrast to previous studies on FeRh bulk, thin films, and nanoparticles, we report the persistence of ferromagnetic order down to 3 K for size-selected 3.3 nm diameter nanocrystals embedded into an amorphous carbon matrix. The annealed nanopartic ...
