How Does Hard Magnetic Soft Matter Deform?
Daniel Katusele, Carmel Majidi, Liping Liu +2
Hard Magnetic Soft Materials, i.e., elastomers seeded with hard magnetic particles, convert magnetic energy into complex motion and have become central to the design of untethered…
Dipolar Self-Interactions Drive Polymer Chain Collapse
Pratik Khandagale, Gal deBotton, Timothy Breitzman +2
We report that a dielectric polymer chain, constrained at both ends, sharply collapses when exposed to a high electric field. The chain collapse is driven by nonlocal dipolar inter…
