This paper lbcuses on the main characteristics of a tree-shaped timber structural system or simply tree-shaped. One of them is the complexity of its steel connections, responsible for the joint of bar elements, compounding a complex structural system, which requires the application of the CYPECAD software version 2007 to solve the calculations problems. Its efficiency was confirmed by a variety of laboratory tests carried out with the whole structure. The tree-shaped is a timber structure that can be used in a large number of destinations, including residences, malls, sheds, hangars, etc.. Originally, it was conceived based on the well-known masterpiece ＂Sagrada Familia＂, whose author was Architect Antoni Gaudi I Cornet （1852-1926） in Barcelona/Spain. It was designed at the end of 19th century and its construction is still not finished. Gaudi inverted the logical order of the gothic concepts, i.e., light weights below and heavy weights above. Based on this concept, he always had in mind the figure of a tree in nature. The tree-shaped follows the same idea, using timber pieces connected by steel plates. Theoretical and numerical analyses have shown its efficiency and lightness for use in timber structures. 展开更多

The rational construction of active targeting liposomes will provide an important structural support for its effective brain targeting.However,there is no clear understanding of the structure-activity relationship of active targeting liposomes.Combining multiscale computational simulation and experimental verification,we established a computational model of RVGP modified PEGylated liposomes(RVGP-PEG-L)and investigated the role of PEG and molecular interaction mechanism of carrier-ligand-receptor.The result indicated that the complex network conformation formed by PEG with 42 monomers(42 PEG)above the density of 8%was the molecular basis for PEG-L to achieve long-circulation function.The lowest monomer number of PEG linker to ensure the targeting ability of RVGP was 42.However,the pose of RVGP binding to nAChR changed after it was linked with PEG-L due to the restraint of PEG chain,leading to a decrease of binding free energy.Increasing the monomer number of PEG linker or improving the non-polarity of polymers was a potential strategy to enhance the combination of RVGP-PEG-L with nAChR on the targeting cell. 展开更多

Transition metal oxides are promising materials for electrochemical energy storage,but they still have the problem of volume change during electrochemical processes.Through the reasonable design of the microstructure of materials,the stress caused by electrode materials during the electron transmission process can be alleviated.This study successfully synthesized MnMoO4 with a yolk-shell structure using a novel selftemplating method.A systematic investigation of the precursor metal ratio(Mn:Mo)and annealing temperature revealed their critical influence on the formation of the yolk-shell structure and the resulting electrochemical performance.When used as a supercapacitor electrode material,MMA-500 delivers a high specific capacitance of 361 F g−1 at a current density of 0.5 A g−1.Additionally,the assembled MMA-500//AC asymmetric supercapacitor showed outstanding cycling stability,maintaining 81.14%capacitance retention after 9000 cycles.This performance surpasses that of most reported MnMoO4-based cathode materials.Our findings provide robust experimental evidence and valuable insights into optimizing the electrochemical performance of yolk-shell structured binary transition metal oxides for energy storage applications. 展开更多

Metal–organic frameworks(MOFs)are a class of porous materials that consist of highly ordered organic building blocks and metal ions/clusters.Because the emerging porous materials have the ability to retain and even enhance the individual functionalities of the secondary building units(SBUs),the catalytic functions of porous MOFs can be therefore easily realized by carefully choosing and tuning the functional moieties in building synthons.Accompanying the development on the synthesis strategy and the characterization technology for MOF materials,MOF catalysts have undergone an upsurge and transcended the stage of opportunism.This brief review will give a cross-section of the rational design and synthesis of porous metal–organic framework materials for heterogeneous catalysis. 展开更多

CONSPECTUS:Photoinduced charge separation(CS)ensures efficient light-energy conversion.The stable and long-lived charge-separation state(CSs)is beneficial for suppressing charge recombination and facilitating the separation of highly reduction-active electrons or highly oxidation-active holes to participate in subsequent photoreactions.Accordingly,the construction of stable and long-lived charge-separation states has been an important goal for researchers.These results highlighted the importance of fullerene materials. 展开更多
