Advanced nanoparticles and methodologies
Time has flown since last post! We were too busy with many things. First, Edouard and Daniel successfully and brilliantly defended their theses in September-October! Congrats to them. It was a pleasure to work with them and we wish them success in their future carriers!
We have two postdoc positions to fill. Please, visit the join us page!
Some people of the group, Fernando, Amandine, Daniel and Edouard attended the International Symposium on Boron, Borides and related materials at Sorbonne Université. Great scientific discussions and congrats to Edouard who won the Award of the PhD student talk!
State-of-the-art synthesis pathways to inorganic materials and nanomaterials are presented in the light of their relationship with geosciences, showing how geological phenomena can inspire innovative synthesis methods and materials.
Geoinspired syntheses of materials and nanomaterials, D. portehault*, I. Gómez-Recio, M. A. Baron, V. Musumeci, C. Aymonier, V. Rouchon, Y. Le Godec, Chemical Society Reviews, 51, 4828 (2022)
We have joined the efforts of Prof. Sylvie Begin-Colin and Prof. Ovidiu Ersen at IPCMS Strasbourg to shed more light on the processes at play during colloidal synthesis of iron oxide nanocrystals. In situ transmission electron microscopy reveals that molecular precursors self-assemble into vesicles, in which nanocrystals nucleate.
In situ liquid transmission electron microscopy reveals self-assembly-driven nucleation in radiolytic synthesis of iron oxide nanoparticles in organic media, N. Ortiz Peña, D. Ihiawakrim, S. Creţu, G. Cotin, C. Kiefer, S. Begin-Colin, C. Sanchez, D. Portehault, O. Ersen, Nanoscale, 14, 10950 (2022)

Our work where we used powder neutron diffraction to study Mn(V) oxide apatites with Universidad Complutense de Madrid has been highlighted by ILL!

We’ll have the pleasure to host, with Prof. Nathalie Vast (Ecole Polytechnique) and Jean-François Halet (NIMS-LINK), ISBB2022, the 21st International Symposium on Boron, Borides and related materials. The conference will be held in Jussieu campus, in Quartier Latin, in September 2022.

We have an opened PhD position with ERC funding! Details for application can be found at the following link: https://bit.ly/3wwBldh
During the last months we have published some papers where we dig in several topics:
Chemistry of silicon-based nanomaterials, from Yang’s work:
Converting silicon nanoparticles into nickel iron silicide nanocrystals within molten salts for water oxidation electrocatalysis, Journal of Materials Chemistry A, 10, 1350 (2022)
A straightforward approach to high purity sodium silicide Na4Si4, Dalton Transactions, 50, 16703 (2021)
Combining nanoparticles with metallurgical processes to design new composites, from Binghua’s work:
Liquid Processing of Bismuth–Silica Nanoparticle/Aluminum Matrix Nanocomposites for Heat Storage Applications, ACS Applied Nano Materials, 5, 2, 1917 (2022)
The group has evolved quite a lot over the last months. We wish a lot of success for the future to Guillaume and Yang who have brilliantly defended their thesis!
And… we welcome the new generation who arrived during the last weeks: Marzena is a new postdoc, geoscientist and interesting in structural transformations in nanomaterials, Emile is master student working on layered materials, Ambroise deals with perovskite oxide nanocatalysts, and Daniel is PhD candidate at Universidad Complutense de Madrid, visiting us for 2 months for nanoscale oxide synthesis.
