In-situ & low-dose electron microscopy.
Due to increasing needs for probing dynamic properties of multifunctional responsive materials or to investigate polymeric/bio-materials of high electron-beam sensitivity, we have acquired and/or customized various types of ancillary equipment in the past few years for in-situ or low-dose electron microscopy. Specifically, electrochemical analysis, cryo-microscopy, and mechanical or mechanoelectrical testing in both TEM and SEM for nano- to micro-scale materials or structures are being explored at present.
