The dependence of the proton-triton thermo-nuclear fusion reaction rate on the temperature and total energy content of the high-energy proton distribution function

Duccio Testa, Christian Schlatter

The endothermic nuclear reaction between thermal tritons and high-energy protons can represent an important contribution to the total neutron yield in tokamak plasmas heated by radio-frequency waves, as the first JET experiments have demonstrated (see Mant ...

Failure in multiphase geomaterias

Lyesse Laloui

The contributions assembled in the present volume proceed from the lectures of the 2009 ALERT Geomaterials School devoted to the Failure in the multiphase geomaterials. The multiphase behaviour of geomaterials used to be mainly considered from the point of ...

Optimization of reaction calorimetry for monitoring chemical reactions in supercritical fluids

Charalampos Mantelis

The PhD thesis deals with the optimization of the reaction calorimetry technique to monitor chemical reactions in supercritical fluids. The aim is to develop this thermal analysis technique to monitor the heat released by a chemical reaction in a high pres ...

Structured fiber supports for ionic liquid-phase catalysis used in gas-phase continuous hydrogenation

Paul Joseph Dyson, Lioubov Kiwi, Gabor Laurenczy, Marina Ruta

Structured supported ionic liquid-phase (SSILP) catalysis is a new concept with the advantages of ionic liquids (ILs) used as solvents for homogeneous catalyst and the further benefits of structured heterogeneous catalysts. This is achieved by confining th ...

Small-scale reactor for data oriented process development

Julien Léo Billeter, Konrad Hungerbühler

During the early stages of research and development chemical industry needs flexible and versatile tools to investigate chemical reaction systems. An important part of the optimisation of a process considering economic factors, risk analysis and environmen ...

Ionic liquid synthesis in a microstructured reactor for process intensification

Albert Renken, Lioubov Kiwi

Ionic liquids (IL) are the focus of growing interest over the last few years due to their low vapour pressure being beneficial for replacing common organic solvents with high vapour pressure. IL synthesised via alkylation are produced in batch or semi-batc ...

Proton-triton nuclear reaction in ICRF heated plasmas in JET

Duccio Testa, Christian Schlatter

Fast protons can react with tritons in an endothermic nuclear reaction which can act as a source of neutrons in magnetically confined fusion plasmas. We have performed an experiment to systematically study this reaction in low tritium concentration (approx ...

Microstructured reactors for catalytic reactions

Albert Renken, Lioubov Kiwi

A review. This review addresses the catalytic reactions performed in microstructured reactors, which are more and more recognized in recent years as a novel approach for chem. and chem. process industry. They are particularly suited for highly exothermic a ...

Microstructured reactors for heterogeneous catalytic processes

Albert Renken

A review; microstructured reactors are mainly characterized by their very-high surface to vol. ratio compared to traditional chem. reactors. Multichannel microreactors having channel diams. in the order of ten to several hundred micrometers have sp. surfac ...
