Quantum chemical studies of reactive species in water

In this thesis, quantum chemical methods have been applied to elucidate the thermodynamics and the kinetics of reactions involving reactive species in water. Due to their high reactivity in water, many transient species are difficult to study by experiment ...

Temperature Sensitivity of Nanochannel Electrical Conductance

Philippe Renaud, Arnaud Bertsch, Mojtaba Taghipoor

Electrical measurement is a widely used technique for the characterization of nanofluidic devices. The electrical conductivity of electrolytes is known to be dependent on temperature. However, the similarity of the temperature sensitivity of the electrical ...

Description of the capacity degradation mechanism in LaNi5-based alloy electrodes

Andreas Züttel, Philippe Mauron, Mariana Spodaryk, Marco Roman Holzer

The mechanism of the capacity degradation of LaNi5-based alloy electrodes was investigated with a special focus on the influence of the alloy and surface composition, as well as the unique structure obtained by gas atomisation. The electrochemical properti ...

Nanocalorimetric platform for accurate thermochemical studies in microliter volumes

Martinus Gijs, Thomas Lehnert, Raphaël Etienne Jean Trouillon, Rima Padovani

A straightforward and general way for monitoring chemical reactions is via their thermal signature. Such approach requires however an experimental setup with a high thermal stability that simultaneously allows time-resolved heat detection with high sensiti ...

Online elemental analysis of process gases with ICP-OES: A case study on waste wood combustion

Christian Ludwig, Marco Wellinger

A mobile sampling and measurement system for the analysis of gaseous and liquid samples in the field was developed. An inductively coupled plasma optical emission spectrometer (ICP-OES), which is built into a van, was used as detector. The analytical syste ...

Development and Application of Devices for Online Trace Element Analysis of Thermal Process Gases from Woody Feedstocks

Marco Wellinger

When using natural or waste wood in thermo-chemical conversion processes, the presence of a number of heteroatoms (e.g. sulfur, chlorine, potassium and sodium or heavy metals) may hinder the processes themselves as well as pose a threat to equipment and/or ...

The calculated difference in the standard heat of formation Delta Delta H-f degrees(298.15) of n- and i-C4H3 center dot free radicals is 37.9 kJ mol(-1) for G3MP2B3 and 45.0 kJ mol(-1) for CCSD(T)-CBS (W 1 U) calculations, which seems to preclude the direc ...

The kinetics of H2O vapor condensation and evaporation on different types of ice in the range 130-210 K

Hubert van den Bergh, Michel Rossi, Pascal Pratte

The kinetics of condensation (kc) and the evaporation flux (J(ev)) of H2O on ice were studied in the range 130-210 K using pulsed-valve and steady-state techniques in a low-pressure flow reactor. The uptake coefficient gamma was measured for different type ...
