Nanometer monocrystalline copper
A smart assembly line for the manufacturing of nanometer monocrystalline copper, the first of its kind in China, became operational in Wenzhou, E.China’s Zhejiang Province on Saturday, indicating one of the key materials for chipmaking has been able for mass production locally.
Chinese scientists report starch synthesis from carbon dioxide
https://phys.org/news/2021-09-chinese-scientists-starch-synthesis-carbon.html
Chinese scientists recently reported a de novo route for artificial starch synthesis from carbon dioxide (CO2) for the first time. Relevant results were published in Science on Sept. 24.
The new route makes it possible to shift the mode of starch production from traditional agricultural planting to industrial manufacturing, and opens up a new technical route for synthesizing complex molecules from CO2.

Qinghai-Tibet Plateau summer rainfall in next 2-10 years can be predicted
Qinghai-Tibet Plateau summer rainfall for the next two to 10 years can be predicted by climate models, according to a new study by Chinese scientists, revealing the predictability of decadal variations of the plateau’s summer rainfall for the first time.
Chinese scientists are also working on predicting the average summer rainfall of the Himalayan region in the next 10 years using climate models, and will share the data with South Asian nations including India for reference and preparations for possible extreme climate events. https://www.globaltimes.cn/page/202106/1225898.shtml
