Welcome to where science resonates!

Materials can be constructed from nanosized building blocks. The properties of such materials then depend on the chemical composition, the morphology, the crystallinity and the spatial organization of these components. We study how properties (e.g. resonance) depend on these characteristics, particularly for application in optics.

July 3, 2020. Laura Ellezam presented a beautiful body of work at Collège de France, combining synthesis of doped ruthenium oxide clusters, PDF measurements and DFT modelling to determine their local structure. I was very impressed and honored to participate in her big day.

May 11, 2020. Antoine Mazel and I are writing a patent “Solution synthesis of silicon particles via coordination complex decomposition”. Together we have developed a fantastic new method to produce silicon particles in solution that will open the way for future research in controlling silicon particle morphology, and creating hybrid materials, such as gold@silicon nanostructures. We will tell you all about it in an upcoming publication!

April 23, 2020. Adèle Hilico has received funding to study our silicon particles in optical tweezers to fully characterize the optical properties of single particles. Well done Adèle!

April 20, 2020. Paul Danty and Antoine Mazel’s work on metal-induced crystallization of titania under microwave radiation has been accepted for publication by Inorganic Chemistry.

March 11, 2020. A project in collaboration with Kevin Vynck was funded today. It is a Mission pour les initiatives transverses et interdisciplinaires, funded by the CNRS, entitled “Synthèse et caractérisation de matériaux nanostructurés produisant des effets visuels inédits” or in English “Synthesis and characterization of nanostructured materials producing unprecedented visual effects”.

February 9-13, 2020. I am on my way to ICONN in Brisbane. Looking forward to meeting up with Australian colleagues!

February 3, 2020. Jie’s article is published! It looks great in press!

October 27-November 1, 2019. I spent the week at Pacrim13, presenting Benoit, Paul and Antoine’s work on the titania crystallization at low temperatures. I was very pleased with how this work was perceived, and for the time with all of the colleagues in Okinawa20191030_212717.jpg

August 5-9, 2019. I’m attending Telluride 2019 in the Blue Mountains, Australia. What a great opportunity to discuss with some fabulous material scientists. I particularly enjoyed discussing with Brian Korgel, Dale Huber and Jim Watkins. Super exciting stuff is on the horizon! Thanks Lucy Gloag and Richard Tilley for organizing.Telluride 2019

July 23-26, 2019. Many of us from the Meta team have gone to Lisbon to participate in Meta 2019. What great talks this year!

July 15, 2019. We’re looking for a new teammate, if you’re looking to do a thesis in nanoparticle synthesis, assembly and optical properties measurements, please contact me.

April 24, 2019. We just submitted a patent entitled “Procédé de séparation d’ions métalliques”, good work Benoît Cormary and Maria Letizia De Marco!

Mar 11-15, 2019. What a fantastic week at the Hybrid Materials conference in Sitges! The highlight was having the opportunity to spend time with Clément Sanchez, marking his 70th birthday. I’m so impressed with all he’s built during his career, what an inspiration to all of us working in inorganic and hybrid materials.
