The anti-snoring nasal mask turned into a black electron microscope for 10 days. This is how it happened recently. A news of a smog-proof nasal mask for 10 days turned into a black electron microscope was followed by netizens. What is the smog particle under the microscope? It is about 2000 times magnified by a scanning electron microscope, and the micron-sized smog particles attached to the filter material fiber can be clearly seen, and the result is shocking. Let's go and see the detailed report!

Liu Yong, an associate professor and doctoral supervisor at Beijing University of Chemical Technology, said that the sample used in the experiment was a filter element with a snorting mask of about 10 days, which was magnified 2000 times by a scanning electron microscope to clearly see the fiber attached to the filter material. Micron-sized smog particles. The experiment found that the filter element of the anti-snoring nasal mask turned black in about 10 days.

By magnifying the scanning electron microscope by about 2000 times, the micron-sized smog particles attached to the filter material fibers can be clearly seen.
The reporter went to the Polymer Nanocomposites Laboratory of Beijing University of Chemical Technology to interview and observe the experiment of smog particles through a desktop scanning electron microscope.

Micron-sized smog particles. According to him, the main observations are solid smog particles, such as calcium carbonate, iron oxide, sulfate, etc. Non-solid aerosols can be seen in another way.
Before and after the New Year, Beijing suffered from continuous smog weather. According to the news released by the Beijing Heavy Pollution Emergency Command, Beijing will continue the orange warning of heavy air pollution until 24:00. Experts remind the public to reduce their outing activities and go out to do protective measures
