MEAM Seminar: “Defending the Planet: The DART Mission, and Mechanics Among the Asteroids”

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

An on-orbit demonstration of asteroid deflection is a key test of our ability to defend the planet from an incoming asteroid. The recent DART (Double Asteroid Redirection Test) mission was NASA's demonstration of kinetic impactor technology, impacting an asteroid to adjust its speed and path. The DART spacecraft impacted the asteroid Dimorphos on September 26, […]

MEAM Ph.D. Thesis Defense: “A Study of Hydrogel Mechanics with Application on the Fracture of Human Blood Clots”

DRLB A6 209 S. 33rd Street, Philadelphia, PA, United States

Loading of biological and synthetic hydrogels involves large deformations, and there exists a large literature devoted to their experimental characterization. Analytical investigations have recognized the importance of contributions originating from the liquid phase, and experiments have verified them. The liquid flux fields in these materials usually exhibit fully three-dimensional profiles and are time-dependent. This coupled […]

MEAM Seminar: “Bringing Microrobots into Biomedicine”

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

Recent progress in diverse disciplines such as soft matter physics, nanoparticle synthesis, nanomedicine, and microbiology has enabled rich opportunities for translation of small-scale robots into medical applications. These robotic systems are providing innovative, high-precision, therapeutic and diagnostic approaches for the treatment of diseases associated with microbial biofilms and are rapidly moving from proof-of-concept studies to […]

MEAM Seminar: “A Symbiotic Philosophy for Bio-inspired Robotics”

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

Humans have frequently looked to natural phenomena to inspire the design of art, structures, and mechanisms. However, there are as many different ways to learn from nature as there are words for this approach: bioinspiration, biomimicry, and biodesign to name a few. In this talk, I propose a taxonomy for categorizing distinct biodesign approaches and […]

MEAM Seminar: “Granular and Photoelastic Avalanches”

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

Flowing granular materials arise everywhere around us, in industry from pharmaceutical processes to bulk good transport lines, and in nature from snow avalanches to captivating dune fields. In landslides, we have an interesting interplay between microscale (grain-grain contacts) and macroscale processes (continuum behavior). In order to understand critical macroscale processes such as stability of a […]

MEAM Seminar: “Hardware / Controls Co-design to Overcome Challenges for Aerial Robots”

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

Aerial robotics have become ubiquitous, but (like most robots) they still struggle to operate at high speed in unstructured, cramped environments. By considering a vehicle's mechanical design simultaneously with the design of controls and automation algorithms, we have more degrees of freedoms to find creative solutions to problems. In this talk I will present some […]

MEAM Seminar: “Advancing the Versatility of Legged Robots and Assistive Devices”

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

Recent years have witnessed tremendous growth in the capabilities of legged robots, with quadrupeds and humanoids demonstrating athletic behaviors that even five years ago were out of reach. Likewise, actively powered lower-limb assistive devices have made great strides in their maturity, with hardware such as the Open-Source Leg broadening access for future breakthroughs. Despite this […]

MEAM Seminar: “Magnetic Fluid Hyperthermia with Magnetic Iron Oxide Nanoparticles: A Case Study in Multi-disciplinary Translational Biomedical Research”

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

Magnetic nanoparticles that are responsive to clinically safe magnetic fields offer multi-modal nanomedicine capabilities. To succeed, complexities of physics and engineering must be addressed to match physical and magnetic properties of magnetic nanoparticles with devices used to activate them. This requires thoughtful design and fabrication of both nanoparticles and devices, with appropriate testing in relevant […]

MEAM Seminar: “Rheological Evaluation of Complex Fluids for Fluid Mechanics Studies”

Towne 315 220 S. 33rd Street, Philadelphia, PA, United States

Recent development of computational fluid mechanics allows to simulate wide range of fluid mechanics problems, but it requires appropriate constitutive equations and rheological properties to represent behavior of complex fluid flows. Standard torque-type rheometer, which is conventional rheometer with assuming ideal constant shear profiles in a thin test fluid layer, however, essential problems on the […]
