Hydrogel-to-Aerogel Transitions in Polymer-Particle Hydrogels Expand the Wildfire Defense Window
Changxin Dong, Samya Sen, Zhennan Ru +4
The 2025 Los Angeles wildfires caused widespread urban destruction and displacement, and severe economic losses, highlighting the urgent need for better fire retardants. Current fi…
Evolving transport properties of dynamic hydrogels enable self-tuning of short- and long-term cargo delivery
Samya Sen, Changxin Dong, Carolyn K. Jons +6
Hydrogels are crosslinked polymer networks with high water content, widely employed in biomedical applications such as drug delivery, tissue engineering, and regenerative medicine.…
Stretching the Printability Metric in Direct-ink Writing with Highly Extensible Yield-Stress Fluids
Chaimongkol Saengow, Samya Sen, Joaquin Yus +7
Direct-ink writing leverages the rheological complexity of yield-stress fluids to construct complex geometries, particularly those with large gaps across internal structures. Howev…
Biomimetic non-ergodic aging by dynamic-to-covalent transitions in physical hydrogels
Samya Sen, Anthony C. Yu, Changxin Dong +2
Hydrogels are soft materials engineered to suit a multitude of applications that exploit their tunable mechanochemical properties. Dynamic hydrogels employing noncovalent, physical…
