Advanced nanoparticles and methodologies
A new study on the reactivity under various atmospheres of nanoscaled metal borides produced from molten salt synthesis is published in Inorganic Chemistry. We have gathered a multidisciplinary consortium, combining advanced nanomaterials synthesis, in situ electron microscopy and synchrotron-based in situ X-ray spectroscopies, to unravel the strong structural reorganization of these nanomaterials.

A new paper on hybrid inorganic-organic gold nanoparticles bearing phase-separated organic shells has been accepted for publication in ACS Nano. We have combined advanced computations, synthesis and electron microscopy, to unveil intermolecular H-bonding as the driving force for phase separation, thus paving the way to controlled dissymetric nano-objects. Many thanks to Marialore Sulpizi (Johannes Gutenberg University Mainz), Frederic Tielens (UPMC) and Ovidiu Ersen (IPCMS Strasbourg) for this stimulating collaboration. DOI: 10.1021/acsnano.7b03616

The second paper of Claire on hybrid gold nanoparticles has just been accepted in Small. We used liquid 1H NMR and DFT to get insight into ligand exchange properties, intermolecular interactions and entropy balance within the mixed ligand shells at the surface of gold nanoparticles. DOI:

We report in Advanced Materials the original surface-driven spin transport in perovskite nanocrystals. This work has been achieved thanks to an original synthesis of nanoparticles in inorganic molten salts. This is our first joint paper with Bernard Doudin’s group a IPCMS-Strasbourg, and José Gonzalez Calbet’s group at UC Madrid. Thanks to all! Looking for future joint achievement! This work is highlighted by the Institute of Chemistry of the CNRS. |

The third paper of Julie, dealing with vanadium oxide-based nanoparticles. It is published in Inorganic Chemistry. A nice collaboration with François Ribot (LCMCP) and Valérie Briois from synchrotron SOLEIL, to enlighten topotactic transformations within oxide nanoparticles.

In this article, we propose a methodology coupling spectroscopic ellipsometry, UV-visible spectroscopy and calculations, aiming at highlighting charge transfers between the core of a gold nanoparticle and the organic shell of capping molecules. Hence, we demonstrate unparalleled charge transfer resulting in a giant shift of the plasmonic response.
