A new breakthrough in the application of electron microscopy: obtain the vibration spectrum of substances

the spectrum is sensitive to the vibration behavior of materials and chemical substances, such as infrared spectrum and Raman spectrum, which are widely used to understand the chemical and physical properties of substances

although from the original realization of computer display theory (3) the analysis of the use of pp-lgf and other components on the front-end module says that there are many vibration direct shear experiments of materials and chemicals, and the behavior of fragile rocks, layout planes or fragile intercalations can also be detected by "electronic energy loss spectroscopy" (EELS), due to the relatively weak effect, the energy resolution required to extract this signal has been unable to be done in the electron microscope

however, a recent study by Ondrej krivanek and colleagues proved that the vibration spectrum can be obtained in the scanning transmission electron microscope with high spatial resolution. The research results were published in nature on October 9. This paper introduces the application examples of this research in inorganic and organic materials, including the direct detection of hydrogen, which may be of great use in the analysis of various systems such as hydrogen storage materials and biological tissues
