Transmission electron microscopy (TEM) analysis is a powerful technique used in materials science and biology to study the structure and properties of materials at the nanoscale. TEM works by transmitting a beam of electrons through an ultra-thin specimen, which interacts with the atoms in the sample to produce high-resolution images and detailed information about the material's morphology, composition, crystal structure, and defects. TEM analysis allows researchers to investigate a wide range of materials, including metals, semiconductors, ceramics, polymers, and biological samples, with resolutions down to the atomic level. This technique is crucial for understanding the properties and behavior of materials in various applications, such as in the development of new materials for electronics, energy storage, and biomedical devices.
