Surfaces of the nearly Kähler S3×S3 preserved by the almost product structure

Miroslava Antić, Zejun Hu, Marilena Moruz, Luc Vrancken

The product manifold S3×S3 is one of the only four homogeneous six-dimensional nearly Kähler manifolds. It also admits a canonical almost product structure P, which is compatible with the almost complex structure (see Bolton et al., Tôhoku Math. J. 67 (2015), 1–17, and Moruz and Vrancken, Publ.…

Oxidation behavior of Al-doped Ti3SiC2-20 wt.%Ti5Si3 composite

Bendiba Guedouar, Youcef Hadji, Abdessabour Benamor, Nabil Chiker, Adel Haddad, Arnaud Tricoteaux, Jean-Pierre Erauw, Vedi Dupont, Fayçal Hadj-Larbi, Mohamed Amine Soualili, Mohamed Hadji

In this work, an aluminum-doped Ti3SiC2-20 wt.% Ti5Si3 composite was prepared through reactive spark plasma sintering (SPS) from a powder mixture of Ti, SiC, C, and Al. The microstructure evolution of the formed oxide scales onto this composite were investigated in the temperature range of 1000–…

Investigation of aluminum nitrate as a set retarder of magnesium potassium phosphate cement: Mechanisms involved in diluted suspension

Céline Cau Dit Coumes, Angélique Rousselet, Biwan Xu, Cyrille Albert-Mercier, sandrine Gauffinet

In this study, the influence of aluminum nitrate on the hydration process of magnesium potassium phosphate (MKP) cement was investigated experimentally and through thermodynamic modelling using diluted systems with Mg/PO$_4$ molar ratio and water-to-cement ratio of 1 and 100 respectively. Three…

Subdivisions of Ring Dupin Cyclides Using Bézier Curves with Mass Points

Lionel Garnier, Lucie Druoton, Jean-Paul Becar, Laurent Fuchs, Géraldine Morin

The paper deals in the Computer-Aided Design or Computer-Aided Manufacturing domain with the Dupin cyclides as well as the Bézier curves. It shows that the same algorithms can be used either for subdivisions of ring Dupin cyclides or Bézier curves. The Bézier curves are described with mass points…

Influence of cetyltrimethylammonium bromide and hydroxide ions on the interfacial tension and stability of emulsions of dodecane in aqueous silicate solutions

Matthieu Bertin, Donatien Gomes Rodrigues, Christel Pierlot, Cyrille Albert-Mercier, Catherine Davy, David Lambertin, Véronique Rataj

This manuscript provides an understanding of the emulsification mechanisms of a model alkane (dodecane) in concentrated aqueous sodium silicate solutions, for e.g. formulating alkane/geopolymer composites for varied applications. To this purpose, we assume that silicate oligomers stabilize the…

Multioutput Gaussian processes with functional data: A study on coastal flood hazard assessment

Andrés F. López-Lopera, Déborah Idier, Jeremy Rohmer, François Bachoc

Surrogate models are often used to replace costly-to-evaluate complex coastal codes to achieve substantial computational savings. In many of those models, the hydrometeorological forcing conditions (inputs) or flood events (outputs) are conveniently parameterized by scalar representations,…

A User-Oriented Local Coastal Flooding Early Warning System Using Metamodelling Techniques

Déborah Idier, Axel Aurouet, François Bachoc, Audrey Baills, José Daniel Betancourt, Fabrice Gamboa, Thierry Klein, Andrés F. López-Lopera, Rodrigo Pedreros, Jérémy Rohmer, Alexandre Thibault

Given recent scientific advances, coastal flooding events can be properly modelled. Nevertheless, such models are computationally expensive (requiring many hours), which prevents their use for forecasting and warning. In addition, there is a gap between the model outputs and information actually…

Mechanical modelling of microwave sintering and experimental validation on an alumina powder

Maxence Renaux, Damien Méresse, Julien Pellé, Anthony Thuault, Céline Morin, Christelle Nivot, Christian Courtois

Microwave sintering (MW) allows fast heating (≤30 min) and densification of ceramic materials, like alumina Al2O3. In order to predict the final material properties (density, size and grain size) the mechanical SOVS (Skorohold Olevsky Viscous Sintering) model is adapted and validated for…

From Metal-Organic Framework Powders to Shaped Solids: Recent Developments and Challenges

Bakytzhan Yeskendir, Jean-Philippe Dacquin, Yannick Lorgouilloux, Christian Courtois, Sébastien Royer, Jérémy Dhainaut

Metal-organic frameworks represent a class of porous materials which developed considerably over the past few years. Their highly porous structure makes them outperforming conventional adsorbents in hot topics such as dihydrogen and methane storage, and carbon dioxide capture. Their consequent…

Influence of dopants on thermal stability and densification of β-tricalcium phosphate powders

Nicolas Somers, Florian Jean, Marie Lasgorceix, Hugo Curto, Giovanni Urruth, Anthony Thuault, Fabrice Petit, Anne Leriche

In this work, β-tricalcium phosphate (β-TCP) is doped with Mg2+ and Sr2+ in order to postpone the problematic β-TCP → α-TCP transition occurring from 1125 °C. Indeed, this phase transition occurs with a large lattice expansion during sintering causing microcracks and a reduced shrinkage leading to…
