Benjamin ABÉCASSIS

CNRS Research Director

I am a physical chemist working at the Chemistry Lab of the École Normale Supérieure de Lyon. My research lies at the interface between materials science, soft matter and nanotechnology.

My main current interest is ultrathin 2D colloidal nanoparticles: their synthesis, surface chemistry and conformation.  I also study the self-assembly of nanocrystals from the perspective of the emergence of collective properties. This implies understanding colloidal forces between particles at the nanoscale. I am also interested in probing the formation mechanism of nanoparticles using in situ synchrotron-based X-ray techniques. I have expertise in Small Angle X-ray Scattering.

I have a PhD (2006) from École Polytechnique and i hold the "habilitation à diriger les recherches" since 2016.

I am pleased to announce two fully funded PhD openings in my group in the framework of the ERC SENECA project: one on synthetic aspects and one on (small angle) scattering. Please see below for details and contact me for further inquiry.

We have an opening for a post doc in theory / simulations of colloidal nanoplatelets. Please see the offer below:erc_postdoc_theory

Our paper paper on the self-assembly of POMS is out in Inorg Chem. This is part of a long term collaboration with G. Izzet's group in Paris.

My SENECA proposal has been selected for funding by the ERC. I am really thrilled with the honour ! This funds will be dedicated to our current efforts to understand the shape control of thin nanoplatelets. There will be openings soon, watch this space !
