FAST radiotelescope in Guiyang officially in operation

The Five-hundred-meter Aperture Spherical radio Telescope (FAST), a single-dish telescope with a diameter of half a kilometer and a receiving area equivalent to about 30 football fields, was officially taken in operation. It is located in a naturally deep and round karst depression in Southwest China’s Guizhou province. Xinhua news release, January 13, 2020

Structure of African swine fever virus elucidated

RAO Zihe and WANG Xiangxi from the CAS Institute of Biophysics and BU Zhigao from the CAS Harbin Veterinary Research Institute have determined the structure of the African swine fever virus (ASFV) at a resolution of 4.1-angstroms, using an optimized image reconstruction strategy. The virus’s structural details will provide strategies for vaccine development. CAS news […]

Graphene nanostructures provide path to quantum materials

GAO Hongjun and colleagues from CAS Institute of Physics have achieved atomically precise folding of graphene nanostructures through STM tip-induced manipulation technology. They were able to fold graphene nanoislands in an arbitrarily chosen direction, constructed bilayer graphene stacks withs a tunable twist angle and a tubular edge connection between the layers, and created intramolecular junctions of […]

Solar energy to methanol pilot plant opened in Lanzhou

The project initiated by LI Can of CAS Dalian Institute of Chemical Physics combines hydrogen production by electrocatalytic water splitting with highly selective, carbon dioxide hydrogenation to methanol. Energy consumption is reduced to 4.0-4.2 kWh / m3 hydrogen. Carbon dioxide hydrogenation to methanol uses a bimetal oxide catalyst (ZnO-ZrO2). Methanol selectivity is greater than 90%, […]

China launches microsatellite for Ethiopia

The wide-range multispectral remote-sensing microsatellite donated to Ethiopia was sent into space together with eight other satellites. Weighing about 65 kg and having a design life of two years, the satellite can obtain remote-sensing data for agriculture, forestry, water conservation, as well as disaster prevention and mitigation. About 20 Ethiopian engineers have been trained in […]

China Academy of Sciences donates digital land map to Mozambique

At the 4th “Digital Silk Road” International Conference held in Shenzhen from Dec. 17, 2019, it was announced that China’s Earth Big Data will support agricultural disaster countermeasures in African countries. Within the “Digital Silk Road Project” (DBAR), the Chinese Academy of Sciences donated to Mozambique data drafting the country’s arable land at 10-meter resolution. […]
