Transmission Electron Microscopy Liquid Electrochemical In Situ SystemTechnical advantages:

Atomic level observation resolution: The ultra-thin silicon nitride window film and 100-200nm ultra-thin liquid layer design of its MEMS chip significantly reduce electron beam scattering interference, enabling clear observation of sample atomic arrangement. In liquid phase environment, a resolution of 0.3nm can be achieved, meeting the requirements of atomic level structural analysis.

High safety and leak proof design: Nanofluidic technology is used to achieve nanoupgraded fluid transportation. The redundant liquid in the system is only in microliters, and the use of polymer membrane surface contact sealing technology increases the sealing area. Compared with traditional O-ring sealing and high flow liquid transportation design, it can effectively avoid liquid leakage and damage to the electron microscope.

Multi field coupling regulation capability: capable of simultaneously applying electrical signals and temperature fields, and can also achieve fluid flow control, supporting multi field coupling experiments of light, electricity, heat, and fluid, and adapting to complex electrochemical scene simulations.

Working Principle:

The electron beam penetrates the liquid pool and interacts with atoms in the sample, generating scattered electrons. The detector receives scattered electronic signals and constructs a sample image. Apply electrical signals through an electrochemical workstation to drive electrochemical reactions in the liquid pool. By combining techniques such as EDS (energy dispersive X-ray spectroscopy) and EELS (electron energy loss spectroscopy), analyze the changes in elemental valence states, chemical composition, and microstructure of the sample during the electrochemical reaction process.
