| 1 | Microstructure and shear strength of the brazed joint of Ti(C,N)-based cermet to steel显示文摘Firm joins were obtained between Ti(C,N)-based cermet and steel with Ag-Cu-Zn-Ni filler metal by vacuum brazing. The effects of technological parameters such as brazing temperature, holding time, and filler thickness on the shear strength of the joints were investigated. The microstructure of welded area and the reaction products of the filler metal were examined by scanning electron microscopy (SEM), metallographic microscope (OM), energy-dispersive X-ray analysis (EDS), and X-ray diffraction (XRD). The brazing temperature of 870°C, holding time of 15 min, and filler thickness of 0.4 mm are a set of optimum technological parameters, under which the maximum shear strength of the joints, 176.5 MPa, is achieved. The results of microstructure show that the wettability of the filler metal on Ti(C,N)-based cermet and steel is well. A mutual solution layer and a diffusion layer exist between the welding base materials and the filler metal. | YE Dameng, XIONG Weihao, Zhang Xiuhai, QU Jun, and YAO Zhenghua State Key Laboratory of Plastic Forming Simulation and Die & Mould Technology, Huazhong University of Science and Technology, Wuhan 430074, China | 2010 | Rare Metals2010，29，1： | 7 |

| 6 | Trefoil-shaped metallacycle and metallacage via heteroleptic self-assembly显示文摘Template-oriented multi-component synthesis method has been proven to be an exceedingly reasonable and excellent method for the synthesis of giant two-dimensional(2D)and three-dimensional(3D)supramolecules,but designing and constructing heteroleptic and controllable self-assembly without unexpected by-products remains a challenge.Here we report two discrete trefoil-shaped metallacycle S1 and metallacage s2 by heteroleptic self-assembly using one hexaphenylbenzene core ligand and two capping ligands.The 2D trefoil-shaped metallacycle S1 could resemble the emblem of the classic'Mitsubishi motif.The use of template-oriented ligand and bent spacer ligand promotes the quantitative formation of the desired 3D trefoil-shaped metallacage S2.The formed metallacage S2 possesses a molecular weight up to 36 kDa,diameter 6.6 nm and height 3.0 nm.All supramolecular coordination complexes were fully characterized by NMR spectroscopy(^(1)H NMR,2D COSY,2D NOESY,2D DOSY),high-resolution electrospray ionization mass sectrometry ESI-MS.ESI-TWIM-MS,TEM and AFM. | Zhilong Jiang He Zhao Jun Wang Bangtang Chen Wenzhi Lv Yiming Li Qiangqiang Dong Die Liu Weiya Liu Min Wang Fan Fu Seok-Ho Hwang Mingzhao Chen Pingshan Wang | 2023 | Chinese Chemical Letters2023，34，12： | 0 |

| 8 | Research on friction law in deep drawing process of rectangular parts显示文摘Friction law is researched in rectangular parts deep drawing using simulation test ma-chine that is used to assess lubricants performance in deep drawing process. Friction coefficientsin different positions on die surface in deep drawing process are measured through probe sensors.Friction coefficients of flange corner, near straight border and far straight border are verified anddescribed quantitatively. It plays an important role in using appropriate lubricants in auto-bodypanel deep drawing process. | LUO Yajun HE Dannong YANG Jianhua ZHANG Yongqing ZHANG Wei LI Jun 1.

| 9 | Highly emissive tribenzotriquinacene-based double-rimed nanocube显示文摘The study of discrete nanosized cages has gone a long way to seek aesthetically appealing structures and to carry out functional applications.Although the construction of supramolecular cages via a bottom-up self-assembly process has been well developed,the sophisticated synthesis still remains a challenge.Here we report the design and assembly of a giant double-rimed nanocube Zn_(24)LH_(8),built with 8 tribenzotriquinacene as six-connected vertices and 24(tpy=terpyridine)connectivities serving as the edges.From the single-crystal structure of tribenzotriquinacene-based ligand LH,the bowl-shaped ligand defines a suitable rigid platform for the spatially well-defined attachment of three sets of parallel vertices,which promotes the quantitative formation of the desired three-dimensional(3D)double-rimed cubic architectures.The formed nanocube Zn_(24)LH_(8)possesses molecular weight up to 25.6 kDa and side length 5.3 nm.Remarkably,the Zn_(24)LH_(8)exhibits strong cyan light emission with high luminescence quantum yields in solution and in the solid state based on the inherent cage-confinement induced emission enhancement.By adding orange-emissive Rhodamine B,emission tuning experiments were achieved including white light emission.This work presents a new system for the imitation of complex assemblies and provides a promising candidate for emissive materials. | Zhilong Jiang Zihao Wu Jun Wang Bangtang Chen Min Wang Weiya Liu Wenzhi Lv Rui Miao He Zhao Die Liu Shenghua Chen Mingzhao Chen Pingshan Wang | 2023 | Nano Research2023，16，7： | 0 |
| 10 | Research of the molecular mechanism of Hai Honghua medicinal liquor in the treatment of fracture based on network pharmacology combined with molecular docking显示文摘Background:Hai Honghua medicinal liquor(HHML),a famous hospital formula composed of 19 traditional Chinese medicines,has been successfully applied in treating soft tissue injury,fresh closed fracture,limb dysfunction after fracture healing,shoulder,neck and leg pain,knee joint pain and other clinical multiple diseases for 30 years in clinical.However,research on the material basis of HHML for the treatment of fracture healing-related disorders is still in a gap.Therefore,it is particularly important to explore the active ingredients,core targets and potential pharmacological mechanisms of HHML to promote fracture healing.Methods:We screened the core active components of each traditional Chinese medicine in formula and its action targets through the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and Encyclopedia of Traditional Chinese Medicine database.The fracture related targets were retrieved from several different public databases,including GeneCards,Online Mendelian Inheritance in Man,DisGeNET and Therapeutic Target Database.Bioinformatics analysis to obtain key bioactive components,underlying targets and signaling pathways,containing the Venn diagram of the intersection with components and diseases gene targets,protein–protein interaction,as well as the Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes analysis,and finally molecular docking.Results:A total of 249 bioactive ingredients of HHML and 325 HHML-fracture-related targets were screened.The network analysis revealed that quercetin,luteolin,kaempferol,Licochalcone A,naringenin and 8-Isopentenyl-kaempferol may be potential candidate agents.Multiple targets are involved including TP53,MAPK3,STAT3,AKT1,MAPK1,HSP90AA1,ESR1 and PIK3CA may be closely linked targets.PI3K-AKT signaling pathway may play a significant role of HHML in treatment of fracture.What’s more,molecular docking suggested that 8-isopentenyl kaempferol,glycyrrhiza chalcone A,and naringenin bound to AKT1,PIK3CA,and ESR1,respectively,exhibiting lower energy and more stable characteristics.Conclusions:The findings indicate the potential active ingredients,target proteins and molecular mechanisms of HHML for the treatment of fractures to provide the exact idea for the next research on the mechanism of action of HHML formula for fracture treatment. | Die Qian Cheng-Xun He Qing Zhang Xiao-Ting Huang Jun Zhao Chi Xu Hong Zhang | 2023 | TMR Integrative Medicine2023，7，12： | 0 |
