    • ESE PhD Thesis Defense: “Engineering copper-vacancy color centers in zinc sulfide for quantum defect discovery”

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

    Photoluminescent point defects, or color centers, in wide-bandgap semiconductors are important platforms for quantum information science because they can be operated as solid-state quantum spin-light interfaces. Implementing so-called defect qubits in an expanded variety of materials systems is beneficial for applications, since the host-defect material properties determine operating parameters such as emission wavelength, spin coherence […]

    MEAM Ph.D. Thesis Defense: “Computational Fluid-Structure Interaction Modeling of the Cardiovascular System”

    /
    Towne 319 220 S. 33rd Street, Philadelphia, United States

    Patient-specific computational modeling and simulation has become a routine part of cardiovascular clinical research. These techniques leverage medical imaging to construct subject-specific models that can be used to study disease processes, design and evaluate medical devices, perform predictive surgery, and aid in clinical decision-making. Modern cardiovascular simulations often require millions of elements and tens of […]

    MEAM Seminar: “Rapidly Understanding Novel Object Dynamics for Robotic Manipulation”

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

    The field of robotic manipulation is attempting to expand from structured warehouse and lab environments to in-the-wild applications in human-centric settings. When deployed in novel settings, a robot may see and need to interact with a new object for the first time. Model-based control approaches rely on a priori dynamics models, an assumption that does […]

    ESE Ph.D. Thesis Defense: “Mobile Mission Planning in Uncertain Environments”

    /
    Berger Auditorium (Room 13), Skirkanich Hall 210 South 33rd Street, Philadelphia, PA, United States

    Robotic mission planning in uncertain environments remains a formidable challenge due to environmental complexity and sensor noise. This dissertation introduces new methodologies to tackle these issues. We develop a method for Linear Temporal Logic (LTL) planning, extending it to completely unknown environments to enable dynamic understanding and task fulfillment. Large language models (LLMs) are also […]

    ESE Seminar: “Fluorite and Wurtzite Structure Ferroelectrics. From Fundamentals to Semiconductor Applications”

    /
    Glandt Forum, Singh Center for Nanotechnology 3205 Walnut Street, Philadelphia, PA, United States

    Ferroelectric properties were initially discovered in perovskite-structured materials over a century ago. However, it was only in the last two decades that these properties were confirmed in fluorite-structured doped HfO2 and wurtzite-structured AlN films, respectively. The ferroelectricity in doped HfO2 or ZrO2 has been attributed to a previously unknown non-centrosymmetric orthorhombic Pca21 phase, while it […]

    Summer 2024 GRASP on Robotics: Sami Atiya, ABB Ltd., “The Evolution of Robotics/AI: an Industry Perspective”

    /
    Wu and Chen Auditorium (Room 101), Levine Hall 3330 Walnut Street, Philadelphia, PA, United States

    This seminar will be held in-person in Wu and Chen as well as virtually via Zoom. ABSTRACT Since its inception, Robotics has constantly used technological developments to address new customer needs. These developments have occurred in two areas: mechatronics and software & control. Mechatronic advances made robots stronger, faster, and more accurate. In parallel, software […]

    • MSE Thesis Defense: “Alloy Anodes for Alkali-Metal Batteries: Elucidating Lithiation Pathways of Metal/Metal Composites and Solid Solution Alloys Using Novel Nanoporous Tri-Layer Metal/Metal/Metal Composites”

    /
    LRSM Reading Room 3231 Walnut St., Philadelphia, PA, United States

    The pressing issues of global warming and the rapid depletion of fossil fuel reserves have prompted both private and governmental organizations to seek clean, renewable energy alternatives. Solar and wind energy have been extensively researched, leading to significantly reduced costs for energy production. However, to address the intermittent nature of these energy sources, reliable methods […]

    MEAM Seminar: “Macroscopic Ensemble Methods for Robot Team Data Collection in Dynamic Environments”

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

    Data is necessary to improve our understanding of dynamic environments, like the ocean. With limited sensing resources, the challenge lies in identifying and acquiring sensor measurements over large spatial and temporal scales. One solution is to use a team of robots equipped with sensors to collect data. However, robot teams still require methods that effectively […]

    Battery technologies are crucial for reducing greenhouse gases by enabling the use of renewable energy and facilitating the transition to electric vehicles, thereby lowering emissions. Lithium metal anodes are ideal for next-generation batteries in automotive applications due to their high energy density. However, issues such as dendrite formation and solid electrolyte interphases (SEI) affect their […]

    MEAM Seminar: “Fingertip Friction, Materials, and Tactile Perception”

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

    Sliding touch is one of the key inputs for the perception of materials in our environment. We are interested in the contribution of fingertip friction to the process of tactile exploration and perception. Psychophysical studies address correlations between subjective judgements of perception and measured physical parameters of interactions, in our case of friction on materials […]
