    Wave turbulence in vibrating plates
    The concept of wave turbulence has been introduced about 50 years ago in the context of water waves. It consists in an asymptotic expansion of the cumulant terms of the dynamics that leads eventually to a kinetic equation. Beside the thermodynamical equilibrium solutions, this kinetic equation exhibits the (...)

    Mechanics and tumor growth}
    Two key elements control the proliferation of tumors. On the one hand, cancer cells accumulate gene mutations. On the other hand, tumors have to interact with neighboring cells and to push on their surrounding in order to grow. Therefore, mechanical stress is one of the important parameters that have to be taken (...)

    And if all bubbles were equal ? Science and applications of monodisperse foams

    Identifying Material Properties from Mechanical Tests
    Material behavior is quantified in terms of a set of “material properties” with a material property being a value, function or functional that can be used to predict responses under a variety of conditions. What constitutes a material property depends on the theory employed. For example, for isotropic linear (...)

    Unravelling Spider' Silks
    In silks, proteins are the structural components and water is the solvent. Protein and water combine and separate - under ambient pressures and temperatures - to make the silk thread, which can be so tough that it outperforms even the best man-made fibres. Spider silk is a case in point for outstanding mechanical (...)

    Roles of icosahedral and crystal-like order in hard spheres glass transition
    A link between local structural ordering and slow dynamics has recently attracted much attention from the context of the origin of glassy slow dynamics. There have been a few candidates for such structural order, icosahedral order, exotic amorphous order, and crystal-like order. Each type of order is linked to (...)

General recommendations for the speakers

The audience is often heterogeneous - because of the wide range of scientific topics covered in the lab - so planning a talk for a broader audience would be preferred. The seminar is in English, and speakers are thus invited to prepare their slides in English.

The seminar starts at 11:30 AM. The speaker is asked to arrive in the lab at least 15 minutes in advance to set up their computer. The talks last typically 45 minutes, and are followed by a discussion time.
