MEAM Seminar: “Architecture in Biological Materials: A Template for Toughness Enhancement, or a Siren Song?”

Structural biological materials, such as animal bones and shells, display remarkable mechanical properties despite being composed of quite simple and ordinary constituent materials. For example, the toughness of nacre, a structural biological material found in the shells of some mollusks, is orders of magnitude higher than that of its primary constituent—the calcium based mineral aragonite. […]

MEAM Doctoral Dissertation Defense: “Problems in Nonlinear Homogenization: Bounds, Estimates, Macroscopic Instabilities, and Post-Bifurcation Response”

This talk is concerned with the use of nonlinear homogenization to study the effective response of composites. We look to illustrate the effect that constitutive assumptions have on the methods by which such estimates can be obtained, as well as on the actual effective, or homogenized, response of the material. Although helpful in ensuring existence […]

MEAM Seminar: “Scalable Fabrication of Nanostructured Energy Storage Systems”

The demand for autonomous devices, including intelligent sensor platforms for IOT applications, is driving a parallel need for efficient energy storage systems that are inexpensive to produce, exhibit high power and energy densities, and occupy a minimum footprint on the device. Necessary enhancement in the performance of batteries and supercapacitors can be realized by fabrication […]

Tedori-Callinan Lecture: “Isogeometric Analysis”

The vision of Isogeometric Analysis was first presented in a paper published October 1, 2005 [1].  Since then it has become a focus of research within both the fields of Finite Element Analysis (FEA) and Computer Aided Design (CAD) and is rapidly becoming a mainstream analysis methodology and a new paradigm for geometric design [2].  […]

MEAM Seminar: “Robot Design Concepts for Intuitive Physical Human-robot Interaction”

Physical human-robot interaction (pHRI) aims at taking advantage of the complementary capabilities of robots and humans. One of the key challenges in pHRI is to provide a high-bandwidth human-robot interaction that is safe and intuitive for the human user. To this end, it is proposed in this work to revisit the design of robots in […]

MEAM Seminar: “Engineering Microdevices Using Atomic Layer Deposition and Electrowetting”

This talk will cover 1) devices created one atomic layer at a time and 2) electrowetting optical elements. Atomic layer deposition (ALD) and Atomic Layer Etching (ALE) are self-limiting processes that enable accurate atomic-scale thickness control either through deposition or etching of various materials. We are developing novel manufacturing processes that study how ALD materials […]

MEAM Seminar: “Dynamical Systems Approach to Geophysical and Aerospace Flows”

A dynamical systems approach is taken to explain the dynamics of two classes of ‘gap-leaping’ geophysical flow as well as the hypersonic second-mode instability. First, in the context of a loop current system, it is shown that multiple steady flow patterns with hysteresis exist and appear to satisfy a cusp catastrophe geometry of solutions. Which […]

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

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 […]

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

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

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 […]
