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.

JF-22 ultra-high-speed wind tunnel

https://www.thesun.co.uk/news/15120985/china-hypersonic-wind-tunnel/ the JF-22 tunnel was capable to simulating flights at Mach 30 or 23,000mph – 30 times the speed of sound.

China’s JF-22 ultra-high-speed wind tunnel is expected to be completed by 2022. It can reproduce flying conditions at an altitude of 40-100 kms at about 30 times the speed of sound. If successful, the cost of satellite and spacecraft launches will be 90% cheaper

China achieves breakthroughs in self-developed no liquid helium dilution refrigerator, targeting the bottleneck problem in quantum computing, as the technology will guard China’s study and development of quantum computing with a steady cryogenic guarantee, according to an announcement from the Institute of Physics, Chinese Academy of Sciences in June. 

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

Hydrogen fuel cell heavy-duty truck

Beiben Trucks Group Co., Ltd. 北奔重型汽车集团有限公司, a Chinese heavy-duty truck producer, has launched a new vehicle powered by 100-kilowatt hydrogen fuel cells. The vehicle’s hydrogen storage cylinders use proton-exchange membrane fuel cells independently developed by Shanghai Jiao Tong University. It can work in extremely cold conditions of minus 30 degrees Celsius.
