Volcano Series In-Situ Holders (Optics&Heating&Double Tilt)

Product Features

Volcano Series In Situ Holders (Optics&Heating&Double Tilt) construct an optical and biasing composite multi field automatic control and feedback measurement system in an in-situ sample stage using a light source introduced by optical fibers and MEMS chips. By combining multiple different modes such as EDS, EELS, SAED, HRTEM, STEM, etc., real-time and dynamic monitoring of the microstructure evolution, phase transition, and elemental valence states of the sample under vacuum environment with changes in light field and temperature can be achieved at the nanoscale or even atomic level Key information such as microstresses and atomic level structure and composition evolution at the surface/interface.

    Surface structure changes of cerium dioxide nanoparticles at 800℃and light.


    The diffusion of the metal alloy was observed at 1300℃,The temperature stability of the  chip is better, The drift rate is very low.


    The carbonization of MOF material was observed during the temperature change from room temperature to1000℃。


    Ag2te-based thermoelectric materials can realize the mutual conversion between electric energy and heat energy through the movement of internal carriers.Therefore, in the process of applying voltage experiment, the temperature of the sample will rise with the increase of voltage. The results show that with the continuous increase of voltage,the surface structure of the sample changes obviously, and the grain changes from irregular block to strip or disappear。In addition, through the process of lowering voltage,we found that  the surface structure change process is reversible when the material increases or decreases the voltage, indicating that the material has excellent thermoelectric performance and reusable performance.
