BE Seminar: “Nanofluidic Technologies for Biomolecule Manipulation”

In the last 20 years, microfabrication techniques have allowed researchers to miniaturize tools for a plethora of bioanalytical applications.  In addition to better sensitivity, accuracy and precision, scaling down the size of bioanalytical tools has led to the exploitation of new technologies to further manipulate biomolecules in ways that has never before been achieved. For […]

MEAM Seminar: “Origami Micro, Bio, and Nanosystems “

Due to the inherent planarity of conventional micro and nanofabrication, it is challenging to pattern and assemble micro, bio, and nano-materials and devices in all three dimensions. Origami inspired mechanical assembly by curving, bending, and folding of appropriately designed micro and nanopatterned precursors provides a high-throughput solution to address this challenge. In this talk, I […]

MEAM Doctoral Dissertation Defense: “High-Dimensional Design Evaluations for Self-Aligning Geometries”

Physical connectors with self-aligning geometry aid in the docking process for many robotic and automatic control systems such as robotic self-reconfiguration and air-to-air refueling. This self-aligning geometry provides a wider range of acceptable error tolerance in relative pose between the two rigid objects, increasing successful docking chances. In a broader context, mechanical alignment properties are […]

MEAM Seminar: “Multi-Stable Morphing Structures”

Variable geometry “morphing” structures can achieve different geometric configurations through overall deformation, but usually many actuators are required for shape control. In this talk we consider a particular type of morphing structure that is able to switch configuration with only a few actuators. It is based on the concept of embedding by design local energy […]

MEAM Special Seminar: “Smartphone-based Mobile Detection Platform for Molecular Diagnostics: from Infectious Diseases to Cancer”

Rapid, quantitative molecular diagnostics in the field, at home, and in resource poor settings is needed for evidence-based disease management, control, and prevention. Conventional molecular diagnostics requires extensive sample preparation, sophisticated instruments, and trained personnel, restricting their use to centralized laboratories. To overcome the limitations of laboratory-based procedures, we designed a simple, inexpensive, hand-held, smartphone-based […]

MEAM Seminar: “The Simulation and Modeling of Turbulent Flows”

Our group at the University of Minnesota focuses on fundamental advances in numerical algorithms, and understanding of flow physics that allow the prediction of engineering turbulent flows. This presentation will discuss key aspects of such simulation alongside illustrative examples. We will discuss a recently developed unstructured overset grid methodology and its application to particle-resolved DNS […]

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].  […]
