Phonon anharmonicities in graphite and graphene

We determine from first principles the finite-temperature properties-linewidths, line shifts, and lifetimes-of the key vibrational modes that dominate inelastic losses in graphitic materials. In graphite, the phonon linewidth of the Raman-active E-2g mode ...

Processing of Graphite-Based Sacrificial Layer for Microfabrication of Low Temperature Co-fired Ceramics (LTCC)

Peter Ryser, Thomas Maeder, Hansu Birol

The processing and application of graphite powder-based sacrificial layer for fabrication of microfluidic structures in LTCC is described. Such layers are produced as pastes, which are screen-printed in LTCC sheets to avoid sagging, by supporting closed, t ...

Electrochemical reactivity at graphitic micro-domains on polycrystalline boron doped diamond thin-films electrodes

Christos Comninellis

This paper deals with the electrochem. reactivity of B doped diamond (BDD) electrodes. A comparative study was carried out to show the influence of the presence of graphitic micro-domains upon the surface of these films. Those graphitic domains are sometim ...

Highly branched polymer/montmorillonite clay nanocomposites

Marlene Rodlert

The aim of this thesis has been to assess the potential of branched polymers as novel exfoliants for layered silicates and their application in polyurethanes. Three different types of –OH functional branched polymers have been studied: dendrimers, hyperbra ...

Methoxylation of p-tert-butyltoluene on boron-doped diamond electrodes

Christos Comninellis

The methoxylation of p-tert-butyltoluene (TBT) in CH3OH-H2SO4-H2O soln. has been investigated on graphite and boron-doped diamond (BDD) anodes. Different reaction intermediates have been found on BDD and graphite. In fact BDD electrodes favor the formation ...

Self-assembled nanowires connected to micropads using the nanostencil method

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart

Electrodeposition on Highly Oriented Pyrolytic Graphite (HOPG) steps has been proven to be an easy method for the preparation of metal (Pd, Cu, Ag etc) and metal oxide or sulfide (MoO2, MnO2, MoS2) nanowires in recent years. These wires can be transferred ...

Heat treatment of carbon anodes for the aluminum industry

Mauriz Lustenberger

Aluminum is produced by the electrolytic reduction of alumina dissolved in molten cryolite. This process requires carbon anodes which are consumed during the electrolysis. The anodes contribute roughly with 15% to the total aluminum production cost. If the ...
