Our core expertise is nanomaterials synthesis. We are focusing on the design of functional nanomaterials, their formation mechanisms, their reactivity and the exploration of new territories in inorganic compositions at the nanoscale, which provide access to properties without equivalent among common compositions.

We are developing original synthesis methods, instrumentation and characterization methods, focusing on new liquid-phase media and reactions. We are targeting a wide range of nanomaterials from oxides to non-oxides that encompass boron-, nitrogen- and silicon-based materials, spanning a wide range of properties, from batteries, thermoelectricity, to spin transport, plasmonics, electrocatalysis and energy conversion.

Carbaboride nanocrystals published in Inorganic Chemistry

We designed the first nanocrystals of sodium carbaboride in molten salts, and unveiled the deviation to ideal stoichiometry that is made possible by a specific molten salt-derived synthesis route and by the nanoscale of the objects. The nanocrystals can act as precursors towards functional boron carbides. This work is part of a Forum of Inorganic …

EuChemS Lecture Award!

David received the 2019 EuChemS Lecture Award! That’s a great honour recognizing the efforts of our group, the collaborative framework within the lab and all collaborators. Thanks to everyone, and see you for the actual lecture, beginning of 2021.

Manganese (V) in oxide and oxyfluoride frameworks published in Chemistry of Materials

We report herein new oxides and oxyfluorides built on the apatite crystal framework and hosting Mn5+, a rare oxidation state of manganese, very scarcely observed in oxides. We take the opportunity of isolating these new solids to provide the first spectroscopic characterization of Mn5+ by EELS and to show the significant ionic conductivity of these …
