| 1 | Deep Structural Framework and Genetic Analysis of Gold Concentration Areas in the Northwestern Jiaodong Peninsula, China: A New Understanding based on High-Resolution Reflective Seismic Survey显示文摘The gold concentration areas in the northwestern Jiaodong Peninsula constituted an important gold metallogenetic region in Eastern China during the Mesozoic. The deep geological bodies' texture characteristic is important for exploring the resources thoroughly and understanding the metallogenic process. The detailed textures were revealed using high-resolution seismic profiles through the three major ore-controlling structures-Sanshandao fault zone, Jiaojia fault zone and Zhaoping fault zone. This study aims to establish a deep structural framework of this area. Based on their formation mechanism, the fault structures developed in the area can be divided into regional and local fault structures. The structural styles are characterised by superimposing their compressional, strike-slip and extensional multi-stage activities. The crust is cut by vertical structures corresponding to a left-lateral strike-slip fault system on the surface. Nearby these structures are the arc-shape structures formed by multi-stage magma intrusions into the upper crust. Bounded by the Tancheng–Lujiang and Muping–Jimo fault zones, the current Jiaodong block, developed a series of NE-trending strike-slip fault systems, was probably formed by the assemblage of several obliquely aligned blocks. The intensive magmatism and hydrothermal activity between the blocks induced large-scale mineralisation. It provides a new angle of view for understanding the cratonic destruction and large ore-concentration formed during the Mesozoic. | YU Xuefeng SHAN Wei XIONG Yuxin GENG Ke SUN Yuqin CHI Naijie GUO Baokui LI Dapeng LI Hongkui SONG Yingxin YANG Deping | 2018 | Acta Geologica Sinica(English Edition)2018，92，5： | 19 |
| 2 | Corrosion engineering boosting bulk Fe_(50)Mn_(30)Co_(10)Cr_(10)high-entropy alloy as high-efficient alkaline oxygen evolution reaction electrocatalyst显示文摘Oxygen evolution reaction(OER)is a critical process in electrocatalytic water splitting.However,the development of low-cost,highly efficient OER electrocatalysts by a simple method that can be used for industrial application on a large scale is still a huge challenge.Recently,high entropy alloy(HEA)has acquired extensive attention,which may provide answers to the current dilemma.Here,we report bulk Fe_(50)Mn_(30)Co_(10)Cr_(10),which is prepared by 3D printing on a large scale,as electrocatalyst for OER with high catalytic performance.Especially,an easy approach,corrosion engineering,is adopted for the first time to build an active layer of honeycomb nanostructures on its surface,leading to ultrahigh OER performance with an overpotential of 247 mV to achieve a current density of 10 mA cm^(-2),a low Tafel slope of 63 mV dec^(-1),and excellent stability up to 60 h at 100 mA cm^(-2)in 1 M KOH.The excellent catalytic activity mainly originates from:(1)the binder-free self-supported honeycomb nanostructures and multi-component hydroxides,which improve intrinsic catalytic activity,provide rich active sites,and reduce interfacial resistance;and(2)the diverse valence states for multiple active sites to enhance the OER kinetics.Our findings show that corrosion engineering is a novel strategy to improve the bulk HEA catalytic performance.We expect that this work would open up a new avenue to fabricate large-scale HEA electrocatalysts by 3D printing and corrosion engineering for industrial applications. | Pengfei Zhou Dong Liu Yuyun Chen Mingpeng Chen Yunxiao Liu Shi Chen Chi Tat Kwok Yuxin Tang Shuangpeng Wang Hui Pan | 2022 | Journal of Materials Science & Technology2022，，14： | 3 |

| 4 | Bioprinted constructs that simulate nerve-bone crosstalk to improve microenvironment for bone repair显示文摘Crosstalk between nerves and bone is essential for bone repair,for which Schwann cells(SCs)are crucial in the regulation of the microenvironment.Considering that exosomes are critical paracrine mediators for intercellular communication that exert important effects in tissue repair,the aim of this study is to confirm the function and molecular mechanisms of Schwann cell-derived exosomes(SC-exos)on bone regeneration and to propose engineered constructs that simulate SC-mediated nerve-bone crosstalk.SCs promoted the proliferation and differentiation of bone marrow mesenchymal stem cells(BMSCs)through exosomes.Subsequent molecular mechanism studies demonstrated that SC-exos promoted BMSC osteogenesis by regulating the TGF-βsignaling pathway via let-7c-5p.Interestingly,SC-exos promoted the migration and tube formation performance of endothelial progenitor cells.Furthermore,the SC-exos@G/S constructs were developed by bioprinting technology that simulated SC-mediated nerve-bone crosstalk and improved the bone regeneration microenvironment by releasing SC-exos,exerting the regulatory effect of SCs in the microenvironment to promote innervation,vascularization,and osteogenesis and thus effectively improving bone repair in a cranial defect model.This study demonstrates the important role and underlying mechanism of SCs in regulating bone regeneration through SC-exos and provides a new engineered strategy for bone repair. | Tianchang Wang Wentao Li Yuxin Zhang Xiang Xu Lei Qiang Weiqiang Miao Xiaokun Yue Xin Jiao Xianhao Zhou Zhenjiang Ma Shuai Li Muliang Ding Junfeng Zhu Chi Yang Hui Wang Tao Li Xin Sun Jinwu Wang | 2023 | Bioactive Materials2023，，9： | 1 |
| 5 | Improvement of titanium alloy TA19 fatigue life by submerged abrasive waterjet peening:Correlation of its process parameters with surface integrity and fatigue performance显示文摘Submerged abrasive waterjet peening(SAWJP)is an effective anti-fatigue manufacturing technology that is widely used to strengthen aeroengine components.This study investigated the correlation of SAWJP process parameters on surface integrity and fatigue life of titanium alloy TA19.SAWJP with different water pressures and standoff distances(SoDs)was conducted on the TA19 specimens.The surface integrity of the specimens before and after SAWJP with different process parameters was experimentally studied,including microstructure,surface roughness,microhardness,and compressive residual stress(CRS).Finally,fatigue tests of the specimens before and after SAWJP treatment with different process parameters were carried out at room temperature.The results highlighted that the fatigue life of the TA19 specimen can be increased by 5.46,5.98,and 6.28 times under relatively optimal process parameters,which is mainly due to the improved surface integrity of the specimen after SAWJP treatment.However,the fatigue life of specimens treated with improper process parameters is decreased by 0.55 to 0.69 times owing to the terrible surface roughness caused by the material erosion.This work verifies that SAWJP can effectively improve the surface integrity and fatigue life of workpieces,and reveals the relationship between process parameters,surface integrity,and fatigue life,which provides support for the promotion of SAWJP in the manufacturing fields. | Gongyu WANG Shulei YAO Yuxin CHI Chengcheng ZHANG Ning WANG Yalong CHEN Rongsheng LU Zhuang LI Xiancheng ZHANG | 2024 | Chinese Journal of Aeronautics2024，37，1： | 0 |
