Since the outbreak of the epidemic, immunoassays based on IgM antibody and IgG antibody of the COVID-19 patients have become an important supplement to nucleic acid-based detection.  Two new antibody reference materials developed by the NIM were now approvaed as national reference materials by the State Administration for Market Regulation. As of March 16, a […]

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 […]

The group of DU Xuemin has developed a contact lense made from a poly(2-hydroxyethyl methacrylate) (pHEMA) hydrogel matrix which features periodic nanostructures, resulting in bright, tunable structural colors ranging from red to green to blue. The spacing of periodic nanostructures within the pHEMA hydrogel are sensitive to changes in moisture and pressure, leading to real-time color changes. Based on these features, […]

The teams of LIU Jian at CAS DICP and LIANG Kun at the Institute of Superconducting and Electronic Materials, University of Wollongong, Australia, have tried defect engineered iron doping for electrocatalytic nitrogen fixation. Using an iron-doped Wolfram18049 catalyst in a nanoreactor, they achieved 24.7 μg / (h * mgcat) yields of NH3 and 20.0% Faraday efficiency at […]

The team of CUI Qiu at CAS Qingdao Institute of Bioenergy and Process Technology (QIBEBT) has reviewed a process for biomass to sugar conversion developed in their own and other groups. The strategy employs cellulosome-producing microorganisms as a biocatalyst to enhance lignocellulose solubilization and produces lignocellulose-derived fermentable sugars as a platform product for fermentations aiming at […]

The team around HOU Xianglin and DENG Tiansheng of the Shanxi Provincial Biorefinery Engineering Technology Research Center at the above institute started out with hydroxymethylfurfural,an intermediate derived from monosaccharides such as glucose, and used used a graphene oxide-supported metal vanadium as a catalyst for oxidation. The best solvents were acetic acid and water. Maleic anhydride is […]

According to the China Academy of Information and Communications Technology (CAICT), China expects over 550,000 5G base stations to be put in operation by the end of 2020. Prefecture-level cities are expected to achieve continuous outdoor connection of the 5G network within this year, with key areas in counties and townships. During the battle against […]
