In situ transmission/scanning transmission electron microscopy (TEM/STEM) measurements have taken a central stage for establishing structure-chemistry-property relationship over the past couple of decades. The challenges for realizing 'a lab-in-gap', i.e., gap between the objective lens pole-pieces, or 'a lab-on-chip', to be used to carry out experiments are being met through continuous instrumental developments. Commercially available TEM columns and sample holder that have been modified for in situ experimentation have contributed to uncovering structural and chemical changes occurring in the sample when subjected external stimulus such as temperature, pressure, radiation (photon, ions, electrons), environment (gas, liquid, magnetic or electrical field), or a combination thereof...
