Visitor Seminar: “Phase Change Heat Transfer for Water and Energy Sustainability”

April 27 @ 10:00 am - 11:00 am

Abstract: Imagine that one day you can drink water wherever air is available, you can grow plants on Mars, you can drive flying cars, and your smartphone never gets hot. Phase change heat transfer will be an essential process in these systems and devices. Condensation and evaporation are two of the most important phase change processes as they have high heat transfer rates. In condensation, the condensate must be rapidly removed to reduce the thermal resistance. In evaporation, the liquid…

MAE Seminar: “Light Plus Sound: Photoacoustic Imaging (PAI) and Photo-mediated Ultrasound Therapy (PUT)”

April 29 @ 10:00 am - 11:00 am

Abstract: Photoacoustic imaging (PAI), also referred to as optoacoustic imaging, is an emerging biomedical imaging technology that is noninvasive, nonionizing, with high sensitivity, satisfactory imaging depth and good temporal and spatial resolution. Like conventional optical imaging, PAI presents the optical contrast which is highly sensitive to molecular conformation and biochemical contents of tissues and can aid in describing tissue metabolic and hemodynamic changes. Unlike conventional optical imaging, the spatial resolution of PAI is not limited by the strong light diffusion…

Visitor Seminar: “The potential applications of bio-inspired 3D electronic microfliers for environmental sensing”

May 2 @ 10:00 am - 11:00 am

Abstract:  Miniaturized, low-cost, wireless electronic devices with meteorological sensors can serve as Lagrangian tracers and provide complementary and important information for pollution sensing, environmental monitoring, storm observations, etc. We developed and examined passive structures designed for controlled, unpowered flight inspired by wind-dispersed seeds, combining fundamental studies in Lagrangian dynamics and novel soft electronics developed for biomedical applications. Controlled mechanical buckling techniques in assembly of three-dimensional (3D) mesostructures provide access to miniature, 3D fliers optimized for such purposes, in processes that…

Visitor Seminar: “Computer Simulations of Mechanical, Thermal, and Mass Transport Across 6+ Length Scales towards Predictive Material Manufacturing”

May 3 @ 10:00 am - 11:00 am

Abstract:  The long-duration space mission demands a paradigm shift from on-ground to in-space ‘born-certified’ manufacturing because material characterization/testing facilities are simply not available there. This is, however, not trivial due to the lack of an approach of correlating in-space manufacturing conditions with the material microstructure evolution in situ. It remains a challenge using traditional single-scale simulation tool to address the complexity induced by the simultaneous occurrence of microscale plastic flow, nanoscale thermal transport, and atomic-level ion hopping in materials when…

Visitor Seminar: “Developing Advanced Solid Propellants and Explosives – Modeling Condensed Phase Materials in Shock-Induced Extreme Conditions”

May 6 @ 10:00 am - 11:00 am

Abstract: Explosives, pyrotechnics, propellants, and fuels are typical classes of energetic materials. These materials have a high amount of stored chemical energy that can be released exothermically. Modeling such materials requires the robust predictions of mechanical-thermochemical material behaviors for initiating reaction and maximizing designated outputs. This talk describes a theoretical continuum framework for modeling energetic materials including how equations of state and chemical kinetics can be improved, and modeling solid phase materials in hydrodynamics system.
