Molecular wiring of LiFePO4 (Olivine)

Michael Graetzel, Ladislav Kavan

The carbon-free LiFePO4 (olivine) was modified by a monolayer coverage with [12-(2,5-di-tert-butyl-4-methoxy-phenoxy)-dodecyl]-phosphonic acid, coded DW. Thin film electrodes were bonded with 5% PVDF and deposited on F-doped SnO2 (FTO) support. The surface ...

Effectiveness factor of thin-layer IrO2 electrocatalyst : influence of catayst loading and electrode kinetics

Dimensionally Stable Anodes (DSA®) are electrodes composed of a metal support and an oxide coating (catalyst). Particularly in this thesis, the Ti/IrO2 electrode was used for the study of the fraction of the surface which participates effectively in the in ...

Multiphysics and Energetic Modeling of a Vanadium Redox Flow Battery

Alfred Rufer

Vanadium redox flow batteries (VRB) are large stationary electricity storage systems; their performance is enhanced when they are operating under optimal conditions. The multiphysics model developed in this paper offers a good understanding of the VRB oper ...

Préparation et caractérisation de nanoparticules bimétalliques (Pt-Au) sur un substrat en diamant dopé au bore : application à l'électrocatalyse

Bahaa El Roustom

Using petrol as a main source of energy, during the 20th century, has caused considerable amounts of damage among which are atmospheric pollution and global warming. At the same time, many geologists and economists expect that the discovery rate of new pet ...

Machining of non-conducting materials using electrochemical discharge phenomenon – An overview

Rolf Wüthrich, Valia Fascio

Machining with electrochemical discharges is an unconventional technology able to machine several electrically non-conductive materials like glass or some ceramics. After almost 40 years of its first mention in literature, this technology remains an academ ...

Chemical and electrochemical promotion of supported rhodium catalyst

Olena Baranova

The chemical and electrochemical promotion of highly dispersed nanofilm Rh catalysts (dispersion: about 10 %, film thickness: 40 nm) has been investigated for the first time. To this end Rh metal was sputter-deposited, either on a purely ionic conductor (8 ...
