Iowa State University‘s Department of Materials Science and Engineering honors Xiaoli Tan, professor, and Zhongming Fan, graduate research assistant, who have made the cover of Applied Physics Letters for their research studying a dual-stimuli in-situ transmission electron microscopy technique. They demonstrated the technique on the relaxor ceramic 0.75(Bi1/2Na1/2)TiO3–0.25SrTiO3 and proved that this technique is indispensable for exploring the rich physics in functional materials.
