Giant voltage-induced deformation in dielectric elastomers near the verge of snap-through instability
Dielectric elastomers are capable of large voltage-induced deformation, but achieving
such large deformation in practice has been a major challenge due to electromechanical
instability and electric breakdown. The complex nonlinear behavior suggests an important
opportunity: electromechanical instability can be harnessed to achieve giant voltage-induced
deformation.

Fracture and debonding in lithium-ion batteries with electrodes of hollow core-shell nanostructures
In a novel design of lithium-ion batteries, hollow electrode particles coated with stiff shells are used to mitigate mechanical and chemical degradation. In particular, silicon anodes of such core-shell nanostructures have been cycled thousands of times with little capacity fading. To reduce weight and to facilitate lithium diffusion, the shell should be thin. However, to avert fracture and debonding from the core, the shell must be sufficiently thick.
