    • MEAM Seminar: “Mechanical Models for DNA”

    /
    Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    We will discuss two complementary mechanical models for DNA that deal with, respectively two problems: one, phase transitions in a DNA molecule, and two, allosteric interactions between two ligands bound to DNA. Experimental studies on single molecules of DNA have reported a rich variety of cooperative structural transitions, including coexistence of three phases, when a […]

    MEAM Doctoral Dissertation Defense: “Additive Manufacturing and Mechanical Properties of Cellulose Nanofibril Materials”

    /
    Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    Cellulose nanofibrils (CNFs) are a nanomaterial derived from plants that have high specific stiffness and strength, can be made into optically transparent materials, and are biodegradable. These properties make CNFs an attractive building block for bulk structural materials. However, CNFs are typically produced in aqueous suspension at low CNF weight fractions (<1 wt.%), which makes […]

    MEAM Seminar: “Delivering Expressive and Personalized Fingertip Haptic Cues”

    /
    Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    The importance of meaningful tactile experiences has become increasingly apparent in areas such as teleoperation, education, and gaming. As the applications of rendering haptic stimuli are growing, so are the requirements of haptic interfaces, in that the intended audience is becoming more diverse and the intended interactions are becoming more complicated. For the past few […]

    MEAM Seminar: “Nano-compatible Neuromorphic Computers: An All-passive Approach to Neural Networks”

    /
    Room 337, Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    This era of the internet of things is poised to experience explosive growth in the number of interconnected smart electronic devices. Machine learning algorithms, such as neural networks, are expected to play an indispensable role in analyzing the data gathered by these devices, and in many cases, will also facilitate informed device responses. However, the […]

    MEAM Seminar: “Small, Autonomous, Flying Robots that can Feel and Map their Environment”

    /
    Room 307, Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    Autonomous flight through unknown environments in the presence of obstacles is a challenging problem for micro aerial vehicles (MAVs). A majority of the current state-of-art research focuses on modeling obstacles as opaque objects that can be easily sensed by optical sensors such as cameras or LiDARs. Since obstacles may not always be opaque, particularly in […]

    MEAM/LRSM Seminar: “Enabling Soft, Flexible 2D Materials and Sensors”

    /
    Reading Room, LRSM 3231 Walnut Street, Philadelphia, PA, United States

    Low temperature synthesis of high quality 2D materials directly on flexible substrates remains a fundamental limitation towards realization of robust, strainable electronics possessing the unique physical properties of atomically thin structures. Here, we describe room temperature synthesis of uniform, stoichiometric amorphous MoS2, WSe2, and other transition metal dichalcogenides and subsequent large area (>5 cm2) photonic […]

    • Penn Engineering Connects: A Reception on Inclusion

    /
    Raisler Lounge (Room 225), Towne Building 220 South 33rd Street, Philadelphia, PA, United States

    A reception on inclusion will be held for new Penn Engineering doctoral students to connect them to their peers and supporting structures within the school. Please join the Dean, Deputy Dean, the Director of the Office of Diversity and Inclusion, faculty and staff leaders including chairs, graduate group chairs and coordinators, and leaders of student groups.
