The cryosphere is the component of the Earth that composed of all solid, frozen water found on Earth. The cryosphere includes water storage areas such as glaciers, iceburgs, snow-covered areas, and sea ice. The cryosphere expands and contracts over the course of the months as average temperatures across the globe fluctuate.
An electron cryomicroscope (CryoTEM) is a TEM with a specimen holder capable of maintaining the specimen at liquid nitrogen or liquid helium temperatures. This allows imaging specimens prepared in vitreous ice, the preferred preparation technique for imaging individual molecules or macromolecular assemblies. TEM is composed of several components, which include a vacuum system in which the electrons travel, an electron emission source for generation of the electron stream, a series of electromagnetic lenses, as well as electrostatic plates. The latter two allow the operator to guide and manipulate the beam as required.
