News and highlights

August 31, 2024: Article about Cobalt and Nickel Phosphides for Catalysis

Our latest work from the ERC NanoFLP research program is out. Here we developped a large-scale robust synthesis of Co2P and Ni2P nanoparticles based on the commercial phosphine HETAP. We also showed that addition of a well-selected second phosphine was able to trigger a low-temperature catalytic hydrogenation of phenylacetylene. Read the article.

July, 2024: Outreach Article about NanoFLPs

Just published in the French journal "L'Actualité chimique": a feature article about our ERC Research program on NanoFLP, or "nanoparticles as partners in Frustrated Lewis Pairs".

It describes our recent works on this topic, with a focus on what where ou guidelines and purposes.

July, 2024: Interview for ARTE

In this series of podcast for the franco-german TV, I was interviewed by journalist Xavier de la Porte to discuss about nanoparticles and conspiracy theories. A very interesting opportunities to bring the debate in front of a broad audience!

July 18, 2024: NanoSea Conference

This international conference, held this year in Marseille, gathers a dynamic community about nanomaterials and their applications. I had the opportunity to give a talk dealing with synthesis and opportunities of our gadolinium-based oxysulfide nanoparticles.

April 28, 2024: GdR Chalco Workshop

I was invited to give a talk in the workshop organized in Rennes by the GdR Chalco about the synthesis and applications of chalcogenides. A great opportunity to learn more about recent trends in the field, and to discuss our latest results about lanthanide oxysulfide nanoparticles.

April 21, 2024: Seminar at CINaM

I spent the day at the Centre Interdisciplinaire de Nanosciences de Marseille (CINaM), to give a seminar and discuss research opportunities and ongoing collaborations with colleagues. An exciting way to discover other facets of Nanosciences than these I am more familiar with!

April, 2024: Défi NAP-XPS

I recently joined this French initiative from the Fédération de Recherche Spectroscopies de Photoémission. Its aim is to promote near-ambient-pressure XPS as a unique spectroscopy to solve scientific questions related to surfaces, catalysis and more.

Refining the NanoFLP Concept

Still fighting to unveil an authentic NanoFLP, we uncovered an interesting low-temperature behavior of Ni nanoparticles in the presence of well-selected phosphine. This could be interpreted as the formation of a surface frustrated Lewis pair for H-H cleavage... but also as a consequence of phenylacetylene activation. What do you make of this?

Carbon is our friend!

Nickel fame for catalysis now extends to a new guy: nickel carbide. In this work, we show that this phase can be used as a catalyst for the hydrgenation of a number of moieties, coming along a greater robustness than the metallic counter-part. Check out our nickel carbide buddy.

Make them safer

It's a small step for the world of nanoparticles, but a big step for our beloved oxysulfides nanoplates: in this work, we propose to evaluate, in a very preliminary approach, some of the interactions of the nanoparticles with macrophage cells. We turned on the lamp (visible light) and monitored the impact in the production of radicals. Read for yourself.

Did you say NanoFLP?

We have been proposing for a while to use metal nanoparticles as partners in Frustrated Lewis Pairs. Now, we found that nickel-cobalt nanoparticles associated to well-chosen phosphines likely form such a pair, based on the correlation between Si-H bond activation and the Tolman cone angle of the phosphine: only a tiny range of steric hindrance is suitable, and it is related to the silane bulkiness. We believe we nailed it. Make your own opinion.

Molybdenum mapped out

Molybdenum is a key element of the energy transition. X-ray absortion spectroscopy at the L-edge is an amazing way to analyze it in solids, liquids, composites, etc. Here, we wrote some simple guidelines to interpret the data and we provided a consistent series of spectra for well-known, and less-know, Mo compounds.
