    1. GO-guided direct growth of highly oriented metal–organic framework nanosheet membranes for  H2/CO2 separation

    Chem. Sci., 2018, Advance Article

    DOI: 10.1039/C7SC04815G

    Researchers in China and Australia report a bottom-up strategy for directly growing a highly oriented Zn2（benzimidazole）4 ZIF nanosheet tubular membrane, based on graphene oxide guided self-conversion of ZnO nanoparticles. The resulting 200 nm thick membrane demonstrated exceptional H2/CO2 gas separation performance, with a H2 performance of 1.4×10-7 mol m-2 s-1 Pa-1 and an ideal separation selectivity of approximately 106. The strategy is particularly suitable for large-scale fabrication of tubular MOF membranes.

    2. 9,10-Azaboraphenanthrene-containing small molecules and conjugated polymers: synthesis and their application in chemodosimeters for the ratiometric detection of fluoride ions

Chem. Sci., 2018, Advance Article DOI: 10.1039/C8SC00688A

    Scientists in China have developed an efficient synthetic procedure for conjugated small molecules and polymers featuring 9,10-azaboraphenanthrene units via aromaticity-driven ring-opening interactions. These molecules and polymers displayed good air and moisture stability, and bright fluorescent properties. The compounds were used as effective and selective ratiometric sensors for fluoride ions in THF solution with 11 anions. The conjugated polymers showed better sensing performance than the molecules due to exciton migration along the conjugated chains.

    1. Cross-linked AIE supramolecular polymer gels with multiple stimuli-responsive behaviours constructed by hierarchical self-assembly

    Polym. Chem., 2018, 9, 2021-2030

    DOI: 10.1039/C8PY00226F

    Here researchers used the principles of hierarchical （step-wise） self-assembly to create stimuli-responsive supramolecular polymer gels. Firstly, the discrete building blocks of the supramolecular structures were synthesised, driven by coordination interactions these self-assembled to create metallacycles. By increasing the concentration of metallacycles and introducing guest molecules the system self-assembled into a crosslinked supramolecular gel. The gels created had aggregation-induced-emission properties and were responsive to stimuli such as temperature and competitive guests.

    2. RAFT polymerization of a RGD peptide-based methacrylamide monomer for cell adhesion

    Polym. Chem., 2018, 9, 1780-1786

    DOI: 10.1039/C7PY01887H

    In this paper a novel RGD peptide-based methacrylamide monomer （MARGD） was synthesised and can be polymerised by RAFT polymerization to afford well-defined polymers （PMARGD） containing a RGD peptide group. In aqueous solutions PMARGD self-assembled into nanoparticles which exhibited pH responsive behaviour, increasing in size as the pH of the solution decreased. Cytotoxicity tests showed biocompatibility.

    Mater. Horiz., 2018, Advance Article

    DOI: 10.1039/C8MH00156A

    Intercalation pseudocapacitive materials enable very fast charging and discharging processes in batteries, which can provide both fast rate capability and high specific capacity. Currently, all the previously reported pseudocapacitive contributions in intercalation/deintercalation reactions are based on various cations （Li+, Na+, Zn2+ etc.）。 In this work, the authors demonstrate that boron-doped graphite sheets can reversibly store anions （PF6-） through both a surface-controlled pseudocapacitive reaction and a diffusion-limited intercalation/deintercalation reaction.

    Biomaterials Science （IF: 4.21）

    1. Interaction of cells with patterned reactors

    Biomater. Sci., 2018, 6, 793-802

    DOI: 10.1039/C7BM00838D

    Researchers created patterned particles through step-wise assembly with a PDMS stamp, strengthened by a final crosslinking step. Then they made the patterned particles into reactors by introducing enzyme-loaded liposomes in between polymer layers. The enzyme used was glucose oxidase, which catalyses the reaction of glucose to hydrogen peroxide. The reactor design successfully influenced the cellular response and the activity of the reactor increased with additional liposome deposition steps.

    哈尔滨工业大学和丹麦奥胡斯大学的研究人员们借助PDMS印章逐步组装合成了一种图案化颗粒，并由最后的一个交联步骤进行强化。之后，他们通过在聚合物层之间引入载有酶的脂质体，将这种图案化颗粒制成了反应器。所使用的葡萄糖氧化酶能够催化由葡萄糖生成过氧化氢的反应。所设计的反应器成功地影响了细胞响应，而且其活性会随着脂质体沉积步骤的增多而增加。
