1, Nature Materials Cover: The use of “phagocytosis” synthesis of functional colloidal particlesUniversity of Bristol Stephen Mann (author) and other people inspired by cell phagocytosis, the preparation of self-driven magnetic Pickering emulsion (MPE), can be selective intake of silica gel particles. After the intake of colloidal particles can selectively transmit and release this water-soluble carrier, while MPE droplets can also be coupled within the enzyme activity. This provides a revelation for the development of colloidal-based new materials and provides a new micrometer-scale regulation for particle synthesis to induce highly ordered behavior.Phagocytosis-inspired behaviour in synthetic protocell communities of compartmentalized colloidal objects（Nature Materials，2017，Doi:10.1038/nmat4916）2, Nature Nanotechnology Cover: Sulfated Glycopeptide Nanostructures are used to activate multifunctional proteins North American University Samuel I. Stupp (Correspondent) et al. Reported supramolecular sulfated glycopeptide nanostructures that extend the signal of bone morphogenetic protein 2 more naturally than the natural sulfated polysaccharide heparin, which promotes Spinal bone regeneration, although far less animal model, but this bioactive nano-structure in the future involved in the field of protein research will have more applications possible.Sulfated glycopeptide nanostructures for multipotent protein activation（Nature Nanotechnology，2017，Doi:10.1038/nnano.2017.109）3, Nature Chemistry Cover: Polyamide-nickel metal polymer University of Bristol Ian Manners (author) and others using the two nickel-nickel monomer through the ring-opening polymerization to form the main chain of poly-nickel-nickel-containing metal polymer, nickel-nickel monomer due to its relatively weak nickel – The interaction between static and dynamic can be converted between each other. At the same time, the study found that the system in the lower concentration, increase the temperature or the existence of a polar solvent, will make poly-lignocene polymerization. The synthetic magnetic material has the potential for data storage and retrieval.Main-chain metallopolymers at the static–dynamic boundary based on nickelocene（Nature Chemistry，2017，Doi:10.1038/nchem.2743）4, JACS cover: reduce the conjugate polymer single, tri-state energy difference universal method Andrew J. Musser and Richard H. Friend of the University of Cambridge and Hugo Bronstein (co-author of the University of London), who introduced a universal method to reduce the single, tri-state energy difference in conjugated polymers, And the receptors are orthogonally connected to spatially separate electrons and holes. This method allows the conjugated polymer to greatly reduce the exchange energy, promote the formation of triplet and thermally excited delayed fluorescence, the mechanism of these two processes through the excited state π – π * and charge transport between the mixed drive.Synthesis and Exciton Dynamics of Donor-Orthogonal Acceptor Conjugated Polymers: Reducing the Singlet–Triplet Energy Gap（JACS，2017，DOI: 10.1021/jacs.7b03327）5, JACS cover: Cu-Oxo cluster catalyzes methane oxidation University of Munich, Johannes A.

Chem. Int. Ed. Cover: Interactions between aromatic-perfluoro aromatic and charge transport in organic concentrating systems (Pyrene-OFN) and pyrene-TCNB were synthesized by supramolecular self-assembly of two typical luminescent organic eutectic pyrene-pyrene-OFNs. It was found that the two intergranular interaction modes exhibited different optical properties, namely, aromatic-perfluoro aromatic (AP) and charge transport (CT) interactions. And the competitive relationship between these two different molecules can be used to produce more complex organic concentrating systems.Competition between Arene–Perfluoroarene and Charge-Transfer Interactions in Organic Light-Harvesting Systems（Angew.

Cover: Single Layer Silicon Embedded Graphite for Lithium Ion BatteriesA single layer Si embedded graphite / carbon mixed electrode (G / SGC) was prepared by Minseong Ko and Jaephil Cho (co-author of the National Institute of Science and Technology), Korea. And the electrodes were compared with commercially available materials under the same conditions. Because SGC has a good compatibility with traditional graphite, and SGC structural characteristics are also very good to determine, so there is a potential application prospects.
