Yodel: A Yield Stress Model for Suspensions

A model for the yield stress of particulate suspensions is presented that incorporates microstructural parameters taking into account volume fraction of solids, particle size, particle size distribution, maximum packing, percolation threshold, and interpar ...

Surface molecular view of colloidal gelation

Sylvie Roke

We investigate the phase behavior of surface-functionalized silica colloids at both the molecular and macroscopic levels. This investigation allows us to relate collective properties such as aggregation, gelation, and aging directly to molecular interfacia ...

Computation of the no-load voltage waveform of laminated salient-pole synchronous generators

Jean-Jacques Simond, Mai Tu Xuan, Stefan Keller

This paper presents a combined analytical and finite-element (FE) method for computation of the no-load voltage waveform of laminated salient-pole synchronous generators. The described method takes into account saturation effects as well as the damper bar ...

Synchronous Generator No-Load Voltage Prediction using a Combined Analytical and FEM Approach.

Jean-Jacques Simond, Mai Tu Xuan, Stefan Keller

A combined analytical and FEM method for prediction of the no-load voltage waveform of laminated salient pole synchronous generators is presented in this article. Very precise prediction of the no-load voltage, including saturation effects as well as the e ...

Method for manufacturing nanostructured thin film electrodes

Ulf Anders Hagfeldt

A method for a binder-free manufg. a nanostructured porous film, e.g. for use in solar cells, includes the steps of prepg. a suspension of semiconducting nanoparticles in a volatile suspension agent, depositing the particle suspension on a conducting subst ...

Prediction of the No-Load Voltage Waveform of Laminated Salient-Pole Synchronous Generators.

Jean-Jacques Simond, Mai Tu Xuan, Stefan Keller

This paper presents a combined analytical and FEM method for prediction of the no-load voltage waveform of laminated salient-pole synchronous generators. The described method takes into account saturation effects as well as the damper bar currents due to t ...

Bimaterial interface fracture: A discrete dislocation model

William Curtin

The influence of mode mixity on crack growth and failure at a metal/ceramic bimaterial interface is examined within the discrete dislocation (DD) plasticity framework. Plasticity occurs via the motion of dislocations embedded in a linearly elastic medium w ...

Force Spectroscopy with a Novel Small Focus AFM

Jürgen Brugger, Johannes Steen

Atomic force microscopy has become potent tool for investigating interand intramolecular interactions. Single molecule force spectroscopy on supramolecular guest-host-complexes reveal information about the depth of the binding pocket and thermal off-rates. ...

Evolution of toxicity during melamine photocatalysis with TiO2 suspensions

César Pulgarin, Juan Kiwi, Sandra Parra Cardona

The fate of melamine has been studied under UV light irradiation (medium pressure mercury arc) in the presence of TiO2 and H2O2. The increase in the concentration of aromatic and aliphatic photo-products were determined in solution concomitantly with the d ...

Adsorption de polycarboxylates et de lignosulfonates sur poudre modèle et ciments

François Perche

Placing concrete requires much more water than the cement needs for its hydration. This results in an important porosity in the hardened concrete, which accentuates the degradation of this material. By adding small amounts of polymeric admixtures, called s ...
