What does TEM mean in ACADEMIC & SCIENCE

The transmission electron microscope (TEM) is a type of electron microscope that uses a beam of electrons to observe very small objects, such as those at the nanoscale. It provides much higher magnifications and resolutions than light microscopes and can provide detailed information about a sample's composition as well.

The TEM works by passing an electron beam through a specimen, allowing it to be viewed on a fluorescent screen. By passing the beam through various lenses, it can be magnified, allowing the user to observe details on incredibly small scales. In addition, due to interactions between the sample and elements in the beam, different materials may absorb different amounts of energy which can help determine what elements are present in a sample.

TEM is often used in scientific research to gain an understanding of nanostructures and their compositions as well as to study biological specimens such as viruses or cells. Its high resolution capabilities also make it useful for failure analysis in industries such as electronics or material science where microscopic examination of components can help identify causes of defects or failures.
