My core expertise is nanomaterials synthesis. I am focusing on the design of functional nanomaterials, their formation mechanisms and the exploration of new territories in inorganic compositions at the nanoscale, which provide access to properties without equivalent among common compositions. To move away from regular nanomaterials (metals, simple metal oxides), I am developing novel synthesis methods, including original instrumentation, and the use of new liquid and gel media. One of my specificities is the wide range of nanomaterials I am exploring, from oxides to borides, polycationics, metals and nitrides, spanning a wide range of properties, from batteries, thermoelectricity, to spin transport and plasmonics.
New paper out in Chem. Eur. J.: we have combined hard templating and the differential reactivity of TiO2 polymorphs to design mixed valence Ti3+/Ti4+ oxide nanoparticles with carbon-free surfaces. The approach enabled us to probe the surface states of the particles with synchrotron radiation.
I am honored to be elected board member of the Solid State Chemistry Division of the French Chemical Society. Thanks for the trust. Hope to be able to promote the field and its interrelations with nanosciences, physics and many others.
We have uncovered a molten salts pathway enabling versatile design of perovskite oxide nanocrystals. Congrats to Naoual and Guillaume for their first paper! Check out this invited paper in ChemNanoMat.
