Particle-size and -density segregation in granular free-surface flows

Christophe Ancey

When a mixture of particles, which differ in both their size and their density, avalanches downslope, the grains can either segregate into layers or remain mixed, dependent on the balance between particle-size and particle-density segregation. In this pape ...

The Impact of Toluene on the Performance of Anode-Supported Ni-YSZ SOFC Operated on Hydrogen and Biosyngas

Christian Ludwig, Jan Van Herle, Stefan Diethelm, Hossein Madi

This paper presents an experimental study of the impact of toluene on the performance of anode-supported (AS) Ni/YSZ SOFC operating at ∼800 °C, 0.25 A/cm2 fed with H2 and biosyngas. Toluene was added to the fuel stream and its concentration increased from ...

The merits of ion cyclotron heating schemes for sawtooth control in tokamak plasmas

Jonathan Graves, Jonathan Marc Philippe Faustin

JET experiments have compared the efficacy of low-and high field side ion cyclotron resonance heating (ICRH) as an actuator to deliberately minimise the sawtooth period. It is found that low-field side ICRH with low minority concentration is optimal for sa ...

Aeration Performances of a Gabion Stepped Weir with and without Capping

Davide Wüthrich

The stepped spillway design has been used for more than 3,300 years. A simple structure is the gabion stepped weir. A laboratory study was performed herein in a large size facility. Three gabion stepped weirs were tested with and without capping, as well a ...

Degradation mechanism of slag blended mortars immersed in sodium sulfate solution

Wei Sun, Karen Scrivener

Additions of slag are usually considered to give cementitious materials which perform well in sulfate bearing environments. This paper compares the deterioration of slag cement blends to those of plain Portland cement and demonstrates that this occurs more ...

Direct determination of niobium at the low nanogram level in mineral waters and freshwaters

Michaël Bensimon

The increasing use of elements such as Nb and Ta in green and information technologies makes it necessary to develop appropriate analytical methods for studying their environmental and ecotoxicological behaviour. This paper describes the first time Nb has ...

Characterizing the Structure and Defect Concentration of ZnO Nanoparticles in a Colloidal Solution

Majed Chergui, Thomas James Penfold, Mercedes Hannelore Rittmann-Frank, Marco Eli Reinhard, Thomas Charles Henry Rossi, Jochen Rittmann

The structure and defect concentration of colloidal solutions of ZnO nanoparticles, synthesized by a sol gel procedure (SG-NP), as well as commercially available ZnO nanoparticles (SA-NP) are investigated by UV-vis absorption spectroscopy, transmission ele ...

Dynamic aggregation of the mid-sized gadolinium complex {Ph-4[Gd(DTTA)(H2O)(2)](-)(3)}

Lothar Helm, Pascal Miéville, Hugues Jaccard

A compound binding three Gd3+ ions, {Ph-4Gd(DTTA)(H2O)(2) (3)} (where H(5)DTTA is diethylenetriaminetetraacetic acid), has been synthesized around a hydrophobic center made up of four phenyl rings. In aqueous solution the molecules start to self-aggre ...
