🔬 LEEMONS | Project updates and partner perspectives

As we enter a new year, the LEEMONS team would like to share a few key updates from the project, combining recent experimental progress with a closer look at the people behind the consortium.

🔹 First passivation results at CSEM

Over the past weeks, the project reached an important milestone with the first passivation test results obtained at CSEM.
While these results remain below our initial expectations, they represent a valuable step forward. They provide important insights into the physical mechanisms at play and already help identify key optimisation pathways for upcoming experimental campaigns.

As is often the case in research and innovation, these early results allow us to refine our hypotheses, adjust experimental protocols, and strengthen the project’s overall technical strategy. The entire consortium remains fully engaged in turning these learnings into tangible progress in the months ahead.

🎥 Meet the Partners – new interview series online
In parallel, and in line with our commitment to transparency, dissemination and collective valorisation, we are pleased to announce the release of a new Meet the Partners interview series on the LEEMONS website.

These interviews give voice to the teams from:
• CSEM – Bertrand Paviet-Salomon
• CEA Leti – FrĂ©dĂ©ric Milesi
• ISC Konstanz – Lejo Joseph & Lacra Popescu
• UMLP – UniversitĂ© Marie & Louis Pasteur – Samuel Queste

They offer direct insight into each partner’s expertise, role and motivation within the project, as well as their perspective on the scientific and technological challenges addressed by LEEMONS.

đź”­ Looking ahead
In the months ahead, LEEMONS will focus on advancing passivation performance, consolidating Zebra metallisation, and moving towards a full M6 manufacturing process at the CEA-Leti premises. Ambitious challenges remain, but the shared commitment and complementary expertise across the consortium continue to drive the project forward!

Thank you to everyone contributing, in one way or another, to the progress of the project.
