Cancer marker detection in human serum with a point-of-care low-cost system

Chemiluminescence, i.e. the emission of light from a chemical reaction, offers interesting opportunities for developing point-of-care biosensors. However, commercially available systems are expensive, bulky, and primarily addressed to laboratory usage. The ...

Kinetics of the solvent-free hydrogenation of 2-methyl-3-butyn-2-ol over a structured Pd-based catalyst

Albert Renken, Lioubov Kiwi, Rocio Micaela Crespo Quesada, Martin Grasemann

The solvent-free selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) was studied over a Pd/ZnO structured catalyst and compared to its behavior in water-assisted conditions. The catalytic behavior was correlated with the s ...

Kinetic hard-modelling and spectral validation of rank-deficient spectroscopic data

Julien Léo Billeter, Konrad Hungerbühler

In recent years, chemometric methods for the analysis of multivariate kinetic data have considerably progressed. Kinetic hard-modelling is one of these methods that is based on the rate law and used to determine the kinetic parameters (e.g. rate constants) ...

Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

New insight into the chemistry of allymetals

Eric Masson

The present thesis work provides new insight into the generation of allylmetal species and into their reactivity toward electrophiles. endo-Allylpotassiums are known to be more stable than their corresponding exo-isomers. The ring strain of methylenecycloa ...

Information extraction from the Evolving Factor Analysis

Simon Crelier, Michael Amrhein

The goal of our project (HES-SO n°11246) is to develop chemometric methods that enhance the development of chemical reactions. Semi-batch experiments are performed using a fully automated chemical reactor. Real-time analytical data, infrared (IR) spectra f ...

Atmospheric heterogeneous reactions of chlorine and bromine containing molecules

Arnaud Aguzzi

This thesis deals with a laboratory study of heterogeneous reactions involving bromine and chlorine containing reservoir species on alkali salt substrates which are relevant to the marine boundary layer, and on ice substrates which are relevant to the lowe ...

Cis-Trans Isomerization in Triply-Bonded Ditungsten Complexes: A Multitude of Possible Pathways

Ursula Röthlisberger

We have investigated different possible mechanisms for the cis-trans isomerization in triply bonded ditungsten complexes with stoichiometry W2Cl4(NHEt)2(PMe3)2 using static d. functional calcns. as well as Car-Parrinello simulations. Our studies reveal an ...

Performance enhancement of a microchannel reactor under periodic operation

Albert Renken, André Rouge

The transient behavior of the dehydration of isopropanol has been studied in a microreactor. The av. productivity under periodic operation is found to be considerably higher compared to steady state even for conversions reaching 80%. The optimal cycle peri ...
