Scientists hope a material which they say can kill bacteria and viruses
could be used in face masks to help tackle the outbreak of the novel coron­
avirus.
The material features nanosilver（纳米银），which has antibacterial prop­
erties,and was made using a process known as melt blowing.This makes
polypropylene microfibers（聚乙烯超细纤维）with a diameter of one micron
（微米），explained Alexander Zhanovich Medvedev,who worked on the pro­
ject and leads a lab of the SBRAS（Siberian Branch of the Russian Academy
of Sciences）.
Medvedev said in a statement that he and colleagues fitted their creation in the inner layer of a conventional three-layer medical mask.Researchers tested the mask against the influenza A virus. When the team compared the new material with that of regular masks,ten thousand times more viruses passed through the latter.
Lyakhov,chief researcher at the SBRAS,said that the material completely deactivates viruses. However,he added it#s unclear exactly how it works,and this problem must be approached in separate

research projects.The team believe the material could protect people against influenza A for up to 10hours,compared to regular masks which need to be changed every one to two hours.The mask is reusable but would be more expensive than regular face masks.
Lyakhov said he spoke to infectious disease specialists who said that as the cloth kills the in­fluenza A virus,"Then most likely other viruses that cause respiratory infections should be exposed to the same effect."
Medvedev said the team had developed a production line so prototypes can be made for testing by specialists.Lyakhov is in close contact with partners in China,he said,and is willing to send sam­ples there for testing.
Dr.Amesh Adalja,an expert,said most people don"t know how to use the masks correctly in order to avoid catching infections.What's more,those rushing out to buy them could lead to supply shortages,meaning health care providers struggle to access them.

q Dear Jim(
冒It's great to hear from you.I feel proud 申knowing your interest in Chinese history.
As for my favourite figure in Chinese history,it must be Wei Yuan,a great thinker
in the late Qing Dynasty.He,in his book,
Haiguo Tuzhi(Maps and Records of the
World),introduced modern technologies and ideas to China.That opened our eyes to the world.In fact,he inspires me to major in English in college,which can be a bridge between China and the world.
Are you interested in knowing more?I can find you some books!Just let me know. Yours,
Li Hua
