How Does Transmission Electron Microscopy (TEM) Facilitate Dynamic Imaging?
In TEM, a beam of electrons is transmitted through a thin sample to form an image. For dynamic imaging, time-resolved TEM (TR-TEM) is used, which involves capturing a series of images or videos to study changes over time. Advanced techniques like environmental TEM (ETEM) allow imaging under different environmental conditions, such as varying temperature and gas atmospheres, making it possible to observe reactions and processes in situ.
