CMDA approves test chip for multiple respiratory viruses
The virus chip was jointly developed by West China Hospital affiliated to Sichuan University, Tsinghua University and a Chengdu-based biotech company, Boao Jingxin Biotechnology Co. With secretion samples collected from patients’ noses and throats, the chip detects six common respiratory viruses including the novel coronavirus all at once within 1.5 hours. Each chip allows the detection of 16 samples in a single assay at the same time.

Chinese-French oceanographic CFOSat satellite put into service
After 8 month in-orbit-testing, the oceanography satellite co-developed by China and France and launched in October 2018 was now put into service. The satellite acquires high-accuracy remote sensing data with its scatterometer and wave spectrometer, and can conduct...
CAS Dalian Institute of Chemical Physics converts biomass fatty acids to long-chain alanes under mild conditions
Researchers around WANG Feng from the Bioenergy Chemicals Research Group have developed a photocatalytic decarboxylation procedure to convert long-chain fatty acids to alkanes under mild conditions. They used low-value long-chain fatty acids from a bio-oil refining...
CAS QIBEBT develops perovskite oxide-based porous membrane for solar-driven evaporation and regeneration
Biological pollutants such as algae, or organic pollutants cause pollution of photothermal films in solar-driven water evaporation. They can be removed by high-temperature degradation, resulting in considerable energy consumption. The group around JIANG Heqing at CAS...
