New paper out: “Cartilage-like tribological performance of charged double network hydrogels”

While we normally work with single-polymer hydrogels, we had the opportunity to work with the Grunlan group at Texas A&M to study their charged double-network hydrogels. These hydrogels are tough! Looking more like cartilage all the time. In this paper we present evidence that their lubrication behavior matches or exceeds that of native cartilage. Higher […]

New paper out: “Compositional Dependence of Polyacrylamide Hydrogel Abrasive Wear Resistance”

Many researchers are aware that hydrogels, even a single kind of hydrogel (polyacrylamide) can be designed to have properties that range from brittle to viscoelastic. It’s truly a versatile material! As hydrogels are being considered as replacements for cartilage in the body, they need to be able to take a beating: they can’t break under […]

Congratulations to Shab on her successful PhD defense on Friday! “Wear mechanisms of chemically crosslinked hydrogels under mild abrasion”

Hydrogels are the next “engineering material” that we need new textbooks for, to teach the next generation of engineers to design with them. Shabnam’s work contributes directly to that, and over the past 4 years she has discovered that the material nature of the hydrogel determines how it wears away — sometimes it acts brittle, […]
