GDR-IRN HOWDI annual meeting

We are glad to announce that the abstract submission is now open for the first HOWDI meeting.

The HOWDI (van der Waals heterostructures of low dimensionality) research group gathers researchers from France and abroad whose investigations focus on the physical properties emerging in van der Waals assemblies. The objective of the GDR-IRN HOWDI is to initiate, sustain and cross-link research activity on graphene, other 2D materials and nanotubes. All information about the network can be found at:

The meeting will be held in Dourdan (Paris area, France) on May 9-13 2022. The participants will be hosted in “Le Domaine du Normont” holiday village for the entire duration of the event. Invited talks, tutorials, contributing talks, poster sessions, and social events are scheduled. All information about the meeting can be found at

Laboratory days

From 12 to 15 October 2021,  LEM staff and some guest researchers presented their research activities during the “laboratory days”.  In a period where smart working is becoming increasingly important, the main objectives of this seminar were to strengthen scientific interactions between lab members and the cohesion of the laboratory. Alternating scientific and technical presentations, round tables and moments of conviviality, the 2021 edition allowed the staff of the laboratory to strengthen their links in a sunny place and in a good mood!

Proof by image – The spaghetti incident

The image “The Spaghetti incident” by Riccardo Gatti and Laurent Korzeczek, selected for the “Proof by image”  2021 competition organized by the CNRS. This image from a numerical simulation illustrates a microstructure of dislocations developing inside a copper sample due to the opening of a crack. It shows the important role of numerical simulations in the understanding and prediction of the collective behavior of these defects associated with the deformation of materials subjected to mechanical and / or thermal stresses.

The twenty selected images of the 2021 competition chosen by the jury composed of image professionals and scientists are available here.
