CIMEX - Centre Interdisciplinaire de Microscopie Electronique de l'Ecole polytechnique
In early 2009, the Irradiated Solids Laboratory (LSI) has made available to other Ecole Polytechnique (LPMC, LPICM, LMS, DCPH and BIOC), Orsay campus (CSNSM) and Saclay plateau (CSM SPAM) laboratories the transmission electron microscope CM30 (LaB6), equipped with STEM and EDX detector. The success of this operation has encouraged the Ecole Polytechnique in late 2009 to acquire a JEOL 2010 FEG equipped with an energy filter GIF Tridiem (EELS). A FEG-SEM Hitachi S-4800 shared between different CIMEX laboratories is also present at the Ecole Polytechnique, as well as a sample preparation room well equipped.
Thus in 2010 was created the Interdisciplinary Center for Microscopy Electronic transmission of the Ecole Polytechnique (CIMEX) gathered around the 4 founders laboratories (LSI LPICM, LPMC and BIOC).
Since then, many microscopists have joined the CIMEX, namely Pierre-Eugène Coulon (IR X, LSI, 2009), Mathias Kobylko (Teacher X, LSI, 2012), Ileana Florea (IR X, LPICM, 2013) and Eric Larquet (IR CNRS, LPMC, 2014). In 2011, the CIMEX and its partners have been winners of the TEMPOS Equipex (Transmission Electron Microscopy at Palaiseau-Orsay-Saclay), covering the acquisition and the maintenance of several advanced electron microscopes in the period 2011-2019. He is also very involved in education and training, through the organization of practical work and workshops on electron microscopy and sample preparation.
Early 2015, 8 microscopists belonging to the 4 laboratories are active in the CIMEX.
The objectives of the CIMEX can be divided into three main directions:
- Giving the opportunity to the Polytechnic School laboratories to perform TEM observations and caracterisations of nanometric systems.
LSI : Composite glasses, nanowires, nanostructured polymers, cements, superconductors, storage glasses, characterization of radiation damage
LPICM : Nanoobjects elaboration (carbone nanotubes, semiconductor nanowires, graphene)
LPMC : Inorganic or hybrid synthesis with a high specific surface, core-shell nanoparticles
BIOC : Understanding biologic cellular networks
- Develop electron microscopy teaching
TREX - Ecole Polytechnique
M2 Nanosciences - Université Paris-Saclay
M2 Ingénierie et Chimie des Biomolécules - Université Paris-Saclay
Licence Professionnelle de Biophotonique - Université Paris Diderot
Annual workshop on cryo-ultramicrotomy in material sciences - partnership with Leica
- Actively participate in the ongoing development on the Saclay plateau of the Integration Center NanoInnov Paris Region
The CIMEX is part of the TEMPOS Equipex (2011-2019). TEMPOS is divided into three parts:
- ChromaTEM (supported by LPS): nano-optics experience combining photons and electrons
- NanoMax (supported by the Ecole Polytechnique): in situ observation of the growth of nano-objects.
- NanoTEM (supported by the LPN): TEM sample preparation by FIB and structural and chemical characterization of samples by advanced electron microscopy.
Finally, new buildings for the CIMEX (~250 m²) are expected for june 2016 on the Polytechnic School campus.
