Investigating the Role of Stem Cell Mechanobiology in Tendon Degeneration
Published: February 17, 2020

Abstract: Tendon and ligament injuries account for 20-30% of all musculoskeletal disorders and are the most common form of non-fatal occupational injury resulting in over 420,000 days away from work each year. A primary cause of tendon degeneration is overuse (i.e., fatigue loading), which produces repeated microscale damage of the load-bearing collagen fibrils as well as […]

Mechanics in Electrochemistry: From Energy Storage to Energy Harvesting
Published: February 10, 2020

Abstract: Rechargeable batteries function by reversible ion shuttling between the electrodes through the electrolytes. However, large amount, high rate ion diffusion and insertion induces large deformation in constituent materials in battery cells, leading to material failure, and consequently irreversible capacity decay and poor cyclability. How do mechanics and electrochemistry reciprocally influence one another in battery […]

Radiation Chemistry, Reactivity and Dynamics in Ionic Liquids and Molten Salts
Published: November 19, 2019

Abstract: Being comprised entirely of charged species, ionic liquids (IL) and molten salts (MS) have dramatically different properties compared to conventional molecular liquids and they provide new and unusual environments to test our understanding  of physical chemistry phenomena. We are interested in how IL and MS properties influence physical and dynamical processes that determine the stability […]

Living Electronics for Bio-interfacing
Published: November 5, 2019

Abstract: Electronic and biological systems represent two limiting thermodynamic models in terms of functioning and information processing. By converging the dynamic and self-adaptable features of bio-machinery and the rationally defined/programmed functionalities of electronic components, there is potential to evolve new capabilities to effectively interrogate and direct biologically significant processes, as well as novel bio-inspired systems/device […]

Instabilities in Soft Materials: Emergent Heterogeneity and Other Surprises
Published: October 18, 2019

Abstract: During development, instabilities develop in the brain, giving it its characteristic wrinkled shape. Other soft tissues, including skin, the bladder, and the airway mucosa, also exhibit instabilities and the resulting folds, wrinkles, and creases. Instabilities in these soft tissues, which often contain multiple layers with distinct properties, are very complex and still not well […]

Ranajay Ghosh: The Extreme Mechanics of Fish Scale Inspired Structures
Published: September 16, 2019

Abstract: Dermal scales appeared early in the evolutionary history of vertebrates, most notably in fishes. Their remarkable multi-functional roles include protection from predatory attacks, enhancement of locomotion, camouflaging and thermal regulation. This has led to a tremendous variation in scale type, material, shape, size and organization among species (e.g. fishes, snakes) as well as within […]
