Fictitious phase separation paper published in Nature Materials
Our work unraveling the strange phase separation in single-phase lithium-intercalating layered oxides appears in Nature Materials. We also reveal that most battery particles are reaction-limited rather than diffusion-limited.

T2 Resistivity in Perovskites
Elongated Fermi surfaces in perovskites like SrTiO3 explain the T2 resistivity, previously thought to be from electron-electron interactions/scattering.
