MEAM Seminar: “Metal and Air Generate Power for Robots”
In many cases, the size and weight of energy storage technologies required to power robotic systems are too large or massive for a robot to carry, leading to limited operational […]
MEAM Seminar: “Accelerated Design of Heterogeneous Materials for Improved Failure Characteristics”
Nature provides countless examples of the use of heterogeneity to enhance the failure properties of materials. Many biological materials, such as bone, marine shells, and fish scales, are extremely resilient […]
MEAM Seminar: “A Differential Homogenization Framework for Precipitation Strengthened Metals”
Precipitation-strengthened alloys are a commercially important class of materials because their mechanical properties can be altered by changing the microstructure through heat-treatment. Specifically, precipitates are introduced into the bulk (matrix) […]
MEAM Seminar: “Exploiting Interface Patterning for Adhesion Control”
Surface force-mediated adhesion, e.g. van der Waals forces, is critical for direct bonding of bulk solids in the absence of an adhesive layer. However, no two surfaces are ideally flat […]
PICS Colloquium: “Kinetic theory for superparameterization of sea ice dynamics”
Arctic sea ice comprises of many ice floes whose dynamics is driven by oceanic/atmospheric currents and floe-floe interaction. Models of the effective sea ice dynamics at large scales typically employ hydrodynamic equations of […]
MEAM Seminar: “Rheological Behavior and Field Statistics of Suspensions of Rigid Particles in Yield Stress Fluids”
Suspensions of non-Brownian particles in fluids are commonly found in nature (e.g. mud, soils, and debris flows) and in the industry (e.g. paints, food, and cosmetics). Understanding the relations between […]
MEAM PhD Thesis Defense: “Modular Robots Morphology Transformation and Task Execution”
Self-reconfigurable modular robots are composed of a small set of modules with uniform docking interfaces. Different from conventional robots that are custom-built and optimized for specific tasks, modular robots are […]
MEAM Seminar: “Some Investigations of Phase Transitions in Rod-like Macro-molecules and Fibrous Gels”
Stress-induced solid-to-solid phase transitions form a large class of phase transitions in nature. They occur in materials that can exhibit different crystal structures under different conditions (stress and temperature), and […]
MEAM PhD Thesis Defense: “Controlled Levitation of Nanostructured Thin Films for Sun-Powered Near-Space Flight”
Earth’s mesosphere is the least studied part of our atmosphere. The data it contains within itself can help develop more comprehensive and accurate models of the atmosphere and can help […]
MEAM PhD Thesis Defense: “Lightweight Structures Enabled by Microfabrication”
Lightweight structures are the product of the science of making systems as light as possible with constraints, which often refer to being sufficiently strong and stiff. Although the development of […]
