Mass Spectrometric and Theoretical Study of Polyiodides: The Connection between Solid State, Solution, and Gas Phases

Paul Joseph Dyson, Zhaofu Fei, Michael Groessl

Polyiodides have been transferred intact from acetonitrile solution to the gas phase and analyzed by mass spectrometry. A range of ions were observed, including I-11, I-13, and I-15, which have higher iodine/iodide ratios than any previously ...

Phase-field simulation of micropores constrained by the dendritic network during solidification

Alain Jacot, Hossein Meidani

A phase-field model has been developed to describe the morphology of pores constrained by a dendritic solid network, and are forced to adopt complex non-spherical shapes. The distribution of the solid, liquid and gas phases was calculated with a multiphase ...

Multi-Valued Spin Switch in a Semiconductor Microcavity

Benoît Marie Joseph Deveaud, François Morier-Genoud, Taofiq Paraïso

In this work, we report on the first realization of multi-valued spin switching in the solid-state. We investigate the physics of spinor bistability with microcavity polaritons in a trap. Spinor interactions lead to special bistability regimes with decoupl ...

3D finite element model of semi-solid permeability in an equiaxed granular structure

Roland Logé

A multi-domain finite element formulation has been applied to determine the semi-solid permeability of an equiaxed granular structure. The granular model was constructed from a Voronoï tessellation algorithm. The liquid-solid interface is represented impli ...

Investigation of the "permanent" electrochemical promotion of catalysis (P-EPOC) by electrochemical mass spectrometry (EMS) measurements

Christos Comninellis, Cyril Falgairette, Chun Xia

The phenomenon of electrochemical promotion of catalysis (EPOC) is most often fully reversible. Subsequent to long-lasting polarization, however, the new steady-state open-circuit catalytic activity after current interruption may remain significantly highe ...

BH4- Self-Diffusion in Liquid LiBH4

Philippe Mauron, Pascal Martelli

The hydrogen dynamics in solid and in liquid LiBH4 was studied by means of incoherent quasielastic neutron scattering. Rotational jump diffusion of the BH4 - subunits on the picosecond scale was observed in solid LiBH4. The characteristic time constant is ...

Compact reactor for continuous multi-phase reactions

Martin Grasemann

The objective of this thesis is the development of a compact reactor for continuous three-phase reactions in single-pass configurations. The design is based on a bubble column reactor staged with layers of catalytic material. To make the reactor suitable f ...

Velocity profiles and interface instability in a two-phase fluid: investigations using ultrasonic velocity profiler

Anton Schleiss, Giovanni De Cesare, Azin Amini

In the present study the velocity profiles and the instability at the interface of a two phase water-oil fluid were investigated. The main aim of the research project was to investigate the instability mechanisms that can cause the failure of an oil spill ...

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

Novel catalytic applications of carbon nanofibers on sintered metal fibers filters as structured supports

Marina Ruta

Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...
