The positions and relative intensities of the peaks yield a fingerprint that can be used for qualitative ph...

The French gravel industry produces approximatively 6.5 million tons of gravel wash mud each year. This material offers very promising properties which require an in-depth characterization study before its use as a construction material, otherwise it is removed from value cycles by disposal in landfills. We examined the suitability of gravel wash m...

The misfit-layered Ca3Co4O9 oxide is being seen as a potential thermoelectric (TE) candidate for high-temperature power generation in air. Since the single crystal depicts a very small size and a low strength, it is worth elaborating grain-oriented Ca3Co4O9 ceramics to capitalize on their anisotropy. Yet, the usual textured pellets are too thin to...
