krióEM

krióEM is a term that refers to a specific area of research or a methodology within the field of materials science and engineering. The prefix "krió" originates from the Greek word for cold, suggesting a focus on cryogenic temperatures or low-temperature processes. The "EM" likely stands for electron microscopy, a powerful technique used to visualize materials at the nanoscale. Therefore, krióEM broadly encompasses the application of electron microscopy techniques at extremely low temperatures.

This approach is particularly valuable for studying materials that are unstable or undergo significant changes at room temperature. By cooling samples to cryogenic temperatures, researchers can preserve their structure, observe transient phenomena, and achieve higher resolution imaging. Examples of applications include the study of cryo-preserved biological samples, the investigation of phase transitions in superconductors, or the analysis of delicate organic molecules. The ability to maintain samples in a frozen, hydrated state is a key advantage of cryo-electron microscopy, allowing for the study of biomolecules in a near-native environment. The development and refinement of krióEM techniques have significantly advanced our understanding of complex materials and biological systems.
