    • MEAM Seminar: “Wave Engineering: From Geometry to Fragility”

    /
    Zoom - Email MEAM for Link peterlit@seas.upenn.edu

    The elastic properties of materials are determined by a few material constants such as the Young’s modulus. Using super-structures one can effectively change these “constants”. In this way we obtain functionalities such as wave-guiding, acoustic lensing or programmable failure. I will show how topological band theory, known from the description of electrons in solids, provides […]

    CBE Seminar: “Phase Behavior and Self-Assembly of Active Colloids”

    /
    Zoom - Email CBE for link

    Abstract In recent years, a new type of synthetic microparticle has captured the imagination of researchers across the physical and biological sciences. These so-called active colloids convert chemical or environmental free energy into irreversible directed motion. Impressively, the active force generated by the particles can lead to self-propelling speeds of tens of hundreds of microns […]

    ODEI Spotlight: The 20th Annual Reverend Dr. Martin Luther King, Jr. Lecture in Social Justice

    /
    https://upenn.zoom.us/j/96715197752

    Dr. Cornel West is Professor of the Practice of Public Philosophy at Harvard University and Professor Emeritus at Princeton University. Cornel West graduated Magna Cum Laude from Harvard in three years and obtained his M.A. and Ph.D. in Philosophy at Princeton. He has written 20 books and has edited 13. He is best known for […]

    BE Seminar: “Designing Biology for Detection and Control” (Pamela A. Silver)

    /

    This seminar will be held virtually - Zoom link coming soon. The engineering of Biology presents infinite opportunities for therapeutic design, diagnosis, and prevention of disease.  We use what we know from Nature to engineer systems with predictable behaviors.  We also seek to discover new natural strategies to then re-engineer.  I will present concepts and […]

    GRASP On Robotics: “Wearable Haptic Devices for Ubiquitous Communication”

    /
    Zoom

    Abstract: Haptic devices allow touch-based information transfer between humans and intelligent systems, enabling communication in a salient but private manner that frees other sensory channels. For such devices to become ubiquitous, their physical and computational aspects must be intuitive and unobtrusive. The amount of information that can be transmitted through touch is limited in large […]

    Faculty panel for Black students in STEM at Penn

    /

    • MEAM Seminar: “Modeling the Behavior of Shape Memory Alloy Structures”

    /
    Zoom - Email MEAM for Link peterlit@seas.upenn.edu

    I will present recent work on the modeling of the structural response of shape memory alloy tubes, bars, and beams. We have developed a new constitutive model that captures pseudoelastic transformation induced recoverable deformation in SMAs including the strong asymmetries in the tensile and compressive responses. Instead of introducing multiple conditions for forward phase transformation, […]

    CBE PhD Dissertation Defense | Exploring the Molecular Origins of Icephilicity Using Specialized Molecular Simulations

    /
    Zoom - Email CBE for link

    Abstract: Exercising control over the formation of ice and similar crystalline structures is important in a variety of contexts, from preserving organs for transplant to preventing clathrate hydrate plugs in natural gas pipelines. To achieve this control, it is crucial to understand nucleation phenomena at the molecular level. Studies have shown that heterogeneous nucleation proceeds […]
