Growth of intermetallic compounds in the Au-In system: Experimental study and 1-D modelling

Michel Rappaz, Aïcha Hessler-Wyser, Léa Deillon

The gold indium system is of primary interest for bonding processes such as solid liquid interdiffusion bonding. In order to optimize the manufacturing parameters, it is essential to know which intermetallic compounds (IMCs) are formed when solid Au and li ...

Incremental Model Identification of Gas-Liquid Reaction Systems with Unsteady-State Diffusion

Benoit Till Cretegny

Identification of kinetic models and estimation of reaction and mass-transfer parameters can be performed using the extent-based identification method, whereby each chemical/physical process is treated individually. This method is used here to analyze gas- ...

Incremental Model Identification of Gas-Liquid Reaction Systems with Unsteady-State Diffusion

Dominique Bonvin, Julien Léo Billeter, Sriniketh Srinivasan, Benoit Till Cretegny

Identification of kinetic models and estimation of reaction and mass-transfer parameters can be performed using the extent-based identification method, whereby each chemical/physical process is handled separately [1-3]. This method is used here to analyze ...

Synthesis and Properties of Highly-Charged Cationic Polyelectrolytes

Hamideh Ahmadloo

Polyelectrolytes (PEL) and PEL complexes formed by electrostatic interaction are recognized as compounds with a remarkable potential for a wide field of applications. However, comprehensive knowledge about electrostatic and structural influences on the pol ...

Efficient determination of diffusion coefficients by monitoring transport during recovery delays in NMR

Geoffrey Bodenhausen, Fabien Ferrage

A novel NMR approach allows one to efficiently determine translational diffusion coefficients of macromolecules in solution. This method for Signal Optimization with Recovery in Diffusion Delays (SORDID) monitors transport occurring during the recovery tim ...

Characterization of the colloidal organic matter from the Amazonian basin by asymmetrical flow field-flow fractionation and size exclusion chromatography

Enrica Alasonati

Colloidal organic matter (COM) collected in small and large watercourse tributaries of the Negro River (Brazil) were fractionated and characterized by an asymmetrical flow field-flow fractionation (AFIFFF) coupled to UV and seven angle laser light scatteri ...

Assessment of metal-extracellular polymeric substances interactions by asymmetrical flow field-flow fractionation coupled to inductively coupled plasma mass spectrometry

Enrica Alasonati

Extracellular polymeric substances (EPSs) excreted by the bacterium Sinorhizobium meliloti and associated Ca, Cd and Pb were characterised by asymmetrical flow field-flow fractionation coupled with UV spectrophotometry and inductively coupled plasma mass s ...

Pore scale analyses of evaporation from porous media

Nima Shokri

Evaporation from porous media is a key process in the hydrologic cycles, waste isolation, biological and food processes and other engineering application. Drying rate and patterns in porous media are strongly influenced by transport properties of the mediu ...

3D Imaging of the Fermi Surface by Thermal Diffuse Scattering

Philip Pattison

We use thermal diffuse scattering of x rays to visualize the lens-shaped portions of the Fermi surface in metallic zinc. Our interpretation of the nature of the observed scattered intensity anomalies is supported by the incorporation of inelastic x-ray sca ...

Development of a hyphenated analytical methodology for the fractionation and characterization of environmental colloids

Enrica Alasonati

Natural colloids are defined as macromolecules and nanoparticles with sizes ranging between 1 nm and 1 µm. Colloidal pool is complex "ill-defined" mixture of humic substances, exopolymeric substances (EPS), inorganic oxides, clays, etc. Aquatic colloids ha ...
