    Lundi 30 juin 2014 11:15-12:15 - Bibliothèque PCT - F3.04
    Nanoscale Models of Single Asperity Friction and Wear
    Understanding friction and wear behavior is limited in part by our lack of a detailed understanding of the atomic scale processes from which energy dissipation and material transfer arise. This has been particularly well illustrated by recent experiments, primarily employing atomic force microscopy (AFM), (...)

    Interrogating the physics of amorphous materials : Mechanics of materials from rubbery to glassy and from the macroscopic to the nanometric
    The mechanics of the materials in the world that surrounds us, at least from the time of Galileo, has fascinated humankind. In the present seminar I will describe our studies of the behavior of amorphous materials with special focus on the use of mechanical measurements to probe fundamental materials physics. (...)

    Bio-adhesive lipid membranes on DNA carpets : confinement, depletion and localized pressure
    It has been recently shown[1] that when a bio-adhesive phospholipid vesicle is brought into contact with a carpeted surface of end-grafted lambda-phage DNAs, the spreading front of the adhesive patch propagates outwards from a nucleation center, acting as a scraper that strongly stretches the DNA chains. Moreover, (...)

    Collective behaviors of bacteria

    Cavitation propagation in natural and artificial (microfabricated) systems

These later are observed naturally in the sap conducting network of trees (...)

    Fast and slow quenches across second order phase transitions : the morphology of structures and the density of topological defects
    When a dissipative macroscopic system is driven through a second order phase transition (a quench) it undergoes an ordering process, usually called phase ordering. Typically, during this process, spatial regions with the order of the (competing) equilibrium phases increase in size and topological defects (be them (...)

    A quantitative approach to microbial population growth using tailored cylindrical yeast colonies
    Microbes can form complex structures composed of millions to billions of cells. These assemblies contrast with the classical view we have of the “unicellulars” microbes. In fact, given their environment, they likely form heterogeneous connected structures, and our understanding of these assemblies is still scarce. (...)

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.
