Phase coexistence enables switching in strained BiFeO3
— Highly strained films of multiferroic BiFeO3 are shown to exhibit a complex and temperature dependent coexistence of multiple phases, with a minority phase being a prerequisite to ferroelectric switching of the majority.

LuFeO3: a new room-temperature multiferroic material
— Atomically resolved scanning transmission electron microscopy (STEM) image of LuFeO3, a new room-temperature multiferroic. Red dots indicate the “buckling” of the Lu oxide plane, consistent with the polar structure.

Fluctuations in ultrasmall nanocrystals induce white light emission
— Combined scanning transmission electron microscopy (STEM) observations and density functional theory (DFT) calculations show why nanoparticles, which typically emit monochromatic light at an energy tuned by their size, suddenly are able to individually emit white light. White-light emission from nanoparticles is of importance due to its potential for energy efficient solid state lighting.
