CAS QIBEBT develops alkane-induced reporter system for monitoring alkane production by algae
The group around Xuefeng LU at QIBEBT studies alkane production by Synechococcus PCC7942 using recombinant aliphatic aldehydes deformylation dioxygenase ( ADO) as the critical enzyme for hydrocarbon production from accumulated triglycerides. Based on promoters from Pseudomonas and Acinetobacter which are triggered by long-chain alkanes, the group constructed a GFP-reporter which allows the rapid screening of high alkane-producing mutants.

CAS QIBEBT develops novel Inducible promoter system for Clostridium
The group around CUI Qiu has developed a new arabinose-based promoter system for C. cellulolyticum which includes an oxygen-independent fluorescent reporter, a sensitive MazF-based counterselection genetic marker and a precise gene knock-out method based on an inducible ClosTron system. The arabinose-inducible gene operation system ARAi has high inducing efficiency and stringency, and ARAi can be applied in both controllable gene expression and precise gene disruption, stimulating the application of Clostridium in the bioconversion of lignocellulosic substrates.

Suzhou researchers develop wearable fibrous perovskite for e-textiles
The group around Qingwen LI at CAS SINANO in Suzhou has coated carbon nanotubes with perovskite, obtaining a bendable fibre which convenrts about 3 % of solar enery into electricity. The prototype material wears down within 4 days due to air and moisture, but the researchers see room to improve the technology for self-powering e-textiles

CAS Dalian Institute of Chemical Physics develops novel microporous polymer for safer drinking water
The group of Weiqiao DENG has developed a perfluorinated conjugated microporous polymer (PFCMP with a super-hydrophobic surface area, which absorbs a wide range of organic solvents, oil, dyes and heavy metal ions with very good adsorption capacity, adsorption kinetics and regeneration. Dye adsorption capacity reached 1377mg/g, lead ion adsorption capacity 808mg/g, arsenic ion adsorption capacity 303mg/g, and the adsorption of organic solvents reached 3000 wt.%. Toluene was removed from water within 40s.

CAS Lanzhou of Chemical Physics creates flexible electronics by simulating rose petals
The group of Zijian CHENG used the concept of rose petal surface structures to develop an elastomeric material which could be used as an elastic substrate for flexible conductive materials. Compared with conventional flat polydimethylsiloxane substrates, elastomeric petals have biomimicking topographic surfaces that can effectively inhibit the propagation of microcracks formed in the conducting layer, which is deposited on top, regardless of the type of conductive materials and the deposition methods.

Group at CAS Institute of Biochemistry and Cell Biology, Shanghai, finds trick for long-term expansion of adult muscle stem cells
Ping HU and colleagues have identified the presence of T cells as critical for prolonged muscle stem cell expansion. By analyzing the the T cell cytokines responsible for this effect and adding them to muscle stem cell cultivations, they achieved 1018 fold cell expansion and stability for over 20 passages.

CAS Kunming Institute of Zoology Institute studies non-mulberry silkworms in view of silk improvement
By epigenetic analysis of genomes of silkworm-related insects, the group of Wen WANG at the CAS Institute of Zoology has generated evidence that disparate features of silk—coloration, retention, strength—are likely not only due to silk proteins, but also to the environment of silk assembly, and more specifically, that stable silk coloration exhibited by some Saturniidae silkmoths may be attributable to active catalytic progress in pigmentation.
