Towards implementing new isotopes for environmental research:Redetermination of the 32Si half-life

Mario Aaron Veicht

The predicted climate changes on Earth will significantly impact the environment and human society. The climate patterns observed during the past centuries led to a better understanding of the driving forces for such changes. However, more studies using ne ...

Micro ion beam analysis for the erosion of beryllium marker tiles in a tokamak limiter

Olivier Sauter, Richard Pitts, Ambrogio Fasoli, Stefano Coda, Basil Duval, Henri Weisen, Yves Martin, Jan Horacek, Javier García Hernández, Duccio Testa, Marco Wischmeier, Federico Nespoli, Patrick Blanchard, David Pfefferlé, Antonio José Pereira de Figueiredo, Jonathan Marc Philippe Faustin, Liang Yao, Dalziel Joseph Wilson, Jonathan Graves, Mikhail Maslov, Joan Decker, Andrea Scarabosio, Cristian Galperti, Gilles Arnoux

Beryllium limiter marker tiles were exposed to plasma in the Joint European Torus to diagnose the erosion of main chamber wall materials. A limiter marker tile consists of a beryllium coating layer (7-9 mu m) on the top of bulk beryllium, with a nickel int ...

Plasma cleaning of beryllium coated mirrors

Cleaning systems of metallic first mirrors are needed in more than 20 optical diagnostic systems from ITER to avoid reflectivity losses. Currently, plasma sputtering is considered as one of the most promising techniques to remove deposits coming from the m ...

Short- and long-range polar order contributions to the Ferroelectric phase of Ca2+ doped SrTiO3

Alexander Tagantsev

Short- and long-range impurity-induced polar ordering in Sr1-xCaxTiO3 (x = 0.014) single crystals was investigated and discussed on the basis of light refraction, morphic birefringence and temperature-dependent dielectric hysteresis loop measurements. Anew ...

Influence of calcium to silica ratio on aluminium uptake in calcium silicate hydrate

Karen Scrivener, Émilie Michèle L'Hôpital

Aluminium uptake in calcium silicate hydrate (C-S-H) was studied at different Ca/Si ratios from 0.6 to 1.6 at 20 degrees C. Aluminium incorporation in C-S-H depends on the total amount of aluminium present in the sample. At low Al/Si ratio (

Field effect modulated nanofluidic diode membrane based on Al2O3/W heterogeneous nanopore arrays

Jürgen Brugger, Philippe Renaud, Arnaud Bertsch, Songmei Wu, Fabien Patrick Wildhaber

We developed Al2O3/W heterogeneous nanopore arrays for field effect modulated nanofluidic diodes. They are fabricated by transferring self-organized nanopores of anodic aluminium oxide into a W thin film. The nanopores are ∼20 nm in diameter and 400 nm in ...

How are small endohedral silicon clusters stabilized?

Anne-Clémence Corminboeuf, Fabrice Avaltroni

Clusters in the (Be, B, C)@Si-n((0,1,2+)) (n = 6-10) series, isoelectronic to Si-n(2-), present multiple symmetric structures, including rings, cages and open structures, which the doping atom stabilizes using contrasting bonding mechanisms. The most strik ...

Al2O3 particle rounding in molten copper and Cu8wt%Al

Andreas Mortensen

We investigate processing-microstructure relationships in the production of Al2O3 particle reinforced copper composites by solidification processing. We show that during production of the composites by gas-pressure infiltration of packed Al2O3 particle pre ...
