Fast temperature cycling of the catalytic CO oxidation using microstructure reactors

Martin Luther

The possibility to increase the performance (productivity or selectivity) of a chemical reactor by using periodic variations of reaction parameters (e.g. reactant concentration or temperature) has been theoretically envisaged since the beginning of the 70t ...

Development and application of an advanced fuel model for the safety analysis of the generation IV gas-cooled fast reactor

Petr Petkevich

Until about the year 2030, current-day nuclear power plants (NPPs) will be replaced by so-called Gen-III or Gen-III+ units, which are mainly based on light water reactor technology. The principal new features are increased safety and improved economical ef ...

Shaken helical track bioreactors: Providing oxygen to high-density cultures of mammalian cells at volumes up to 1000L by surface aeration with air

Florian Maria Wurm, David Hacker, Xiuwei Zhang, Mathieu Benjamin Stettler

A new scalable reactor was developed by applying a novel mixing principle that allows the large-scale cultivation of mammalian cells simply with surface aeration using air owing to increased liquid–gas transfer compared to standard stirred-tank bioreactors ...

Supercritical Reaction Calorimetry: Versatile Tool for Measuring Heat Transfer Properties and Monitoring Chemical Reactions in Supercritical Fluids

Thierry Meyer, Charalampos Mantelis

The heat flow reaction calorimetry technique was developed for reactions with supercrit. fluids and was applied to monitor the free-radical dispersion polymn. of Me methacrylate in supercrit. carbon dioxide (scCO2). The main math. equation for the calorime ...

Synchrotron X-Rays for Microstructural Investigations of Advanced Reactor Materials

Manuel Alexandre Pouchon, Wolfgang Hoffelner, Maria Samaras

X-rays from synchrotron beamlines provide a powerful tool for materials analysis in circumstances where long-term materials degradation under complex loading conditions (e.g., temperature, irradiation, and stress) becomes important. This may occur for adva ...

Reaction monitoring of the MMA polymerization at marginal dispersion stability

Thierry Meyer, Charalampos Mantelis

The free-radical dispersion polymn. of Me methacrylate was studied using the reaction calorimetry technique. An esp. developed calorimeter for use with supercrit. fluids was employed and a set of expts. was explicitly designed to isolate the effect of the ...
