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 […]

Electrochemical Energy Systems
Published: September 9, 2019

Abstract: Demand of batteries keeps increasing as electronic devices get widespread and fossil-based systems are being replaced by electricity-based systems. Lithium-ion battery has been considered one of the most promising power sources for mobile and transportation systems, but it faces challenging issues of high cost, low capacity (i.e. short operation hours or driving ranges), and […]

Real-Time Sea-State Estimation From Measurement Of A Ship’s Motion in Waves
Published: September 9, 2019

Abstract: In standard seakeeping simulations of a ship in irregular seas, the rigid body motions of the ship are computed using a set of semi-analytic integro-differential equations, which model the response of the ship including non-linear and history dependent forces.    Using this type of model allows one to model the response of the ship in […]
