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 […]
