Correlative image learning of chemo-mechanics in phase-transforming solids
Constitutive laws underlie most physical processes in nature. However, learning such equations in heterogeneous solids (for example, due to phase separation) is challenging. One such relationship is between co...

Current-induced transition from particle-by-particle to concurrent intercalation in phase-separating battery electrodes
Many battery electrodes contain ensembles of nanoparticles that phase-separate on (de)intercalation. In such electrodes, the fraction of actively intercalating particles directly impacts cycle life: a vanishin...
