25-9 China issues long-term guideline on IP

China’s State Council and the CPC recently issued a guideline on building up its intellectual property (IP) strength between 2021 and 2035. By 2035, China’s overall IP competitiveness will be at the forefront of the world as a world-class IP powerhouse with Chinese characteristics on six aspects: China will build a comprehensive, well-structured, IP legal […]

27-9 CAS Shanghai converts syngas aerosols to medium- and long-chain chemicals using Clostridium ljungdahlii

A group around Weihong JIANG at CAS Institute of Plant Sciences in Shanghai metabolically engineered autotrophic Clostridium ljungdahlii to efficiently co-produce three important bulk chemicals, isopropanol, 3-hydroxybutyrate (3-HB), and ethanol (together, IHE), using syngas (CO2/CO). The engineered strain was further optimized to reassimilate acetic acid and synthesize 3-HB by introducing heterologous functional genes. Finally, the […]

24-9 Team at CAS Tianjin Institute of Industrial Biotechnology synthesises starch from CO2 in a cell-free system

The group used computational design to draft an artificial anabolic pathway from CO2 to starch.  First, CO2 is reduced to methanol by an inorganic catalyst. Next, in a cell free system with spatial and temporal segregation, methanol is covered to starch through 11 core reactions driven by hydrogen and including engineered enzymes. Reaction rates in […]

13-9 China launches Gaofen 5-02 satellite for hyper spectral observation of air pollution

The satellite developed by the CAS Hefei Institute of Material Science is equipped with a total of 7 remote sensing instruments, including a main greenhouse gas monitor (GMI), an atmospheric trace gas differential absorption spectrometer (EMI), a multi-angle polarization detector (DPC) and a high-precision polarization scanner (POSP). The four payloads operate synchronously for a dynamic […]

13-9 Hydrogen from decoupled water electrolysis may regulate electricity peak loads

DENG Denghui’s group at the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences wants to use hydrogen as a green energy carrier to balance peaks and troughs in power consumption. To this end, they use polysulfides as a mediator in a galvanostat, lowering the reduction potential for the formation of hydrogen to […]
