Shulou(Shulou.com)11/24 Report--

Thanks to CTOnews.com netizens and special commentators for their clue delivery! On April 22, CTOnews.com, the global press conference of "High Spatio-temporal Resolution Electron microscope" of City University of Hong Kong was held simultaneously at City University of Hong Kong and Shenzhen Futian Research Institute of Hong Kong University. This microscope is the first high spatio-temporal resolution electron microscope with its own intellectual property rights in China, and it is also the first compact electron microscope with low voltage, field emission, scanning and transmission integrated mode in the world.

In order to overcome the radiation damage and the bottleneck of still image samples, the research team of the University of Hong Kong has designed pulsed electron sources and fast cameras that can be used by desktop electron microscopes. Because the team has the relevant intellectual property rights and is free to design the system, the price of specific electron microscopes is expected to be reduced to 60% of similar products on the market.

Appendix to CTOnews.com:

This high space-time resolution electron microscope is composed of four key systems and other supporting instrument control components: vacuum system, pulsed electron beam emission system, aberration correction electron optics system and fast imaging system. High spatio-temporal resolution imaging of nanometer scale can be achieved in low voltage system. By reducing the damage caused by high-energy electron beam, it can observe many vulnerable samples and see material details as small as Omicron virus.
