| 1 | Natural Variation in CCD4 Promoter Underpins Species-Specific Evolution of Red Coloration in Citrus Peel显示文摘Carotenoids and apocarotenoids act as phytohormones and volatile precursors that influence plant development and confer aesthetic and nutritional value critical to consumer preference.Citrus fruits display considerable natural variation in carotenoid and apocarotenoid pigments.In this study,using an integrated genetic approach we revealed that a 5;c/s-regulatory change at CCD4b encoding CAROTENOID CLEAVAGE DIOXYGENASE 4b is a major genetic determinant of natural variation in C3 0 apocarotenoids responsible for red coloration of citrus peel.Functional analyses demonstrated that in addition the known role in synthesizing 3-citraurin,CCD4b is also responsible for the production of another important C3 0 apocarotenoid pigment,p-citraurinene.Furthermore,analyses of the CCD4b promoter and transcripts from various citrus germplasm accessions established a tight correlation between the presence of a putative 5'c/s-regulatory enhancer within an MITE transposon and the enhanced allelic expression of CCD4b in C3 0 apocarotenoid-rich red-peeled accessions.Phylogenetic analysis provided further evidence that functional diversification of CCD4b and naturally occurring variation of the CCD4b promoter resulted in the stepwise evolution of red peels in mandarins and their hybrids.Taken together,our findings provide new insights into the genetic and evolutionary basis of apocarotenoid diversity in plants,and would facilitate breeding efforts that aim to improve the nutritional and aesthetic value of citrus and perhaps other fruit crops. | Xiongjie Zheng Kaijie Zhu Quan Sun Weiyi Zhang Xia Wang Hongbo Cao Meilian Tan Zongzhou Xie Yunliu Zeng Junli Ye Lijun Chai Qiang Xu Zhiyong Pan Shunyuan Xiao Paul D.Fraser Xiuxin Deng | 2019 | Molecular Plant2019，12，9： | 18 |

| 3 | Fabrication of ultrafine ZnFe2O4 nanoparticles for efficient photocatalytic reduction CO2 under visible light illumination显示文摘A one-pot, solvent-thermal process was used to create the ultrafine ZnFe_2O_4 nanoparticles photocatalyst.During the solvent-thermal process, the in situ self-forming NaCl not only served as a 'cage' to confine the ion diffusion, but also acted as a microreactor for nanocrystallite growth. An average particle size of ~10 nm and a high-specific surface area of~112.9 m^2/g were observed for the ultrafine ZnFe_2O_4 nanoparticles Owing to the synergistic effect of ultrafine particle size, the full utilization of the visible light region and high conduction band(CB) position, ultrafine ZnFe_2O_4 photocatalyst displayed an efficient photocatalytic CO_2 reduction under visible light illumination. Besides, the ultrafine ZnFe_2 O_4 photocatalyst showed high production selectivity for CH_3CHO and C_2H_5OH generation in aqueous CO_2/NaHCO_3 solution. This work may provide a new idea for the synthesis of new high-efficiency photocatalysts. | Jun xiao Weiyi Yang Shuang Gao Caixia Sun Qi Li | 2018 | Journal of Materials Science & Technology2018，34，12： | 6 |
| 4 | Microstructure and properties of novel Al-Ce-Sc,Al-Ce-Y,Al-Ce-Zr and Al-Ce-Sc-Y alloy conductors processed by die casting,hot extrusion and cold drawing显示文摘In order to overcome the trade-off between the strength and electrical conductivity of aluminum alloy conductors,the new Al-Ce-Sc,Al-Ce-Y,Al-Ce-Zr and Al-Ce-Sc-Y alloys were prepared by die casting,high temperature homogenization treatment,hot extrusion and cold drawing.Adding Sc and Y eliminated the dendrite segregation of the as-cast Al-0.2 Ce alloy and promoted the formation of equiaxed grains with the average grain size of 142.5μm.The Al-0.2 Ce-0.2 Sc-0.1 Y alloy inherited the great tensile properties of Al-0.2 Ce-0.2 Sc alloy and the high electrical conductivity of Al-0.2 Ce-0.1 Y alloy simultaneously.After cold drawing and annealing at 200℃for 5 h,the ultimate tensile strength of Al-0.2 Ce-0.2 Sc-0.1 Y alloy reached 200 MPa and 198 MPa,the elongation reached 6.8%and 8.5%,and the electrical conductivity reached 61.01%and 61.77%,respectively.The main second phase of Al-0.2 Ce-0.2 Sc-0.1 Y alloy after hot extrusion were Al_(13)Fe_3 Ce containing a few Y and Si atoms.The larger size and proportion of the second phase greatly reduced the concentration of solute Fe and Si atoms and the addition of Y significantly decreased the density of defects after cold drawing compared to Al-0.2 Ce-0.2 Sc alloy,which improved electrical conductivity of the alloy.Furthermore,the dispersed and coherent nano-size Al_3 Sc precipitions of Al-0.2 Ce-0.2 Sc-0.1 Y alloy greatly improved strength,elongation and heat resistance.Compared with Al-0.2 Ce-0.2 Sc alloy,the lower density of dislocation,stacking fault and subgrain boundary and the larger size of Al_3 Sc precipitions with enrichment of Y atoms enable the Al-0.2 Ce-0.2 Sc-0.1 Y alloy to maintain high strength,elongation and electrical conductivity after annealing. | Weiyi Wang Qinglin Pan Geng Lin Xiaoping Wang Yuqiao Sun Xiangdong Wang Ji Ye Yuanwei Sun Yi Yu Fuqing Jiang Jun Li Yaru Liu | 2020 | Journal of Materials Science & Technology2020，58，23： | 4 |

| 6 | Simulation of Centennial-Scale Drought Events over Eastern China during the Past 1500 Years显示文摘The characteristics and causes of centennial-scale drought events over eastern China during the past 1500 years were explored based on simulations of the Community Earth System Model(CESM). The results show that centennial-scale drought events over eastern China occurred during the periods of 622–735(Drought period 1, D1) and 1420–1516(Drought period 2,D2) over the past 1500 years, which is comparable with climate proxy data. In D1, the drought center occurred in northern China and the Yangtze River valley; however, in southern China, precipitation was much more than usual. In D2, decreased precipitation was found across almost the whole region of eastern China. The direct cause of these two drought events was the weakened East Asian summer monsoon, and the specific process was closely linked to the air–sea interaction of the Indo-Pacific Ocean. In D1, regions of maximum cooling were observed over the western Pacific, which may have led to anomalous subsidence, weakening the Walker circulation, and reducing the northward transport of water vapor. Additionally, upward motion occurred over southern China, strengthening convection and increasing precipitation. In D2, owing to the decrease in the SST, subsidence dominated the North Indian Ocean, blocking the low-level cross-equatorial flow, enhancing the tropical westerly anomalies, and reducing the northward transport of moisture. Additionally, descending motion appeared in eastern China, subsequently decreasing the precipitation over the whole region of eastern China. The anomalous cooling of the Indo-Pacific Ocean SST may have been caused by the persistently low solar irradiation in D1; whereas, in D2,this characteristic may have been influenced not only by persistently low solar irradiation, but frequent volcanic eruptions too. | Weiyi SUN Jian LIU Zhiyuan WANG | 2017 | Journal of Meteorological Research2017，31，1： | 4 |

| 8 | Efficient oxygen reduction reaction by a highly porous,nitrogen-doped carbon sphere electrocatalyst through space confinement effect in nanopores显示文摘A highly porous nitrogen-doped carbon sphere(NPC)electrocatalyst was prepared through the carbonization of biomass carbon spheres mixed with urea and zinc chloride in N_(2) atmosphere.The sample carbonized at.1000℃ demonstrates a superior oxygen reduction reaction(ORR)performance over the Pt/C electrocatalyst,while its contents of pyridinic nitrogen and graphitic nitrogen are the lowest among samples synthesized at the same or lower carbonization temperatures.This unusual result is explained by a space confinement effect from the microporous and mesoporous structures in the microflakes,which induces the further reduction of peroxide ions or other oxygen species produced in the first step reduction to water to have the preferred overall four electron reduction ORR process.This work demonstrates that in addition to the amount or species of its aptive sites,the space confinement can be a new approach to enhance the ORR performance of precious-metal-free,nitrogen-doped carbon electrocatalysts. | Zheyang MO Weiyi YANG Shuang GAO Jian Ku SHANG Yajun DING Wuzhu SUN Qi LI | 2021 | Journal of Advanced Ceramics2021，10，4： | 3 |
| 9 | Multi-scale mechanotransduction of the poroelastic signals from osteon to osteocyte in bone tissue显示文摘In order to quantify the poroelastic mechanical signals conduction and evaluate the biomechanical effectiveness of functional units(osteocyte processes,canaliculi and lacuna)in lacunar-canalicular system(LCS),a multiscale poroelastic finite element model was established by using the Comsol Multiphysics software.The poroelastic mechanical signals(pore pressure,fluid velocity,von-Mises stress,strain)were analyzed inside the osteon-osteocyte system.The effects of osteocyte(OCY)’s shape(ellipse and circle),long axis directions(horizontal and vertical)and mechanical properties(Elastic modulus and permeability)on its poroelastic responses were examined.It is found that the OCY processes is the best mechanosensor compared with the OCY body,lacunae and canaliculi.The mechanotransduction ability of the elliptic shaped OCY is stronger than that of circular shaped.The pore pressure and flow velocity around OCYs increase as the elastic modulus and permeability of OCY increase.The established model can be used for studying the mechanism of bone mechanotransduction at the multiscale level. | Xiaogang Wu Chaoxin Li Kuijun Chen Yuqin Sun Weilun Yu Meizhen Zhang Yanqin Wang Yixian Qin Weiyi Chen | 2020 | Acta Mechanica Sinica2020，36，4： | 2 |

| 12 | Post-illumination activity of Bi_(2)WO_(6) in the dark from the photocatalytic“memory”effect显示文摘Photocatalysts with the photocatalytic'memory'effect could resolve the intrinsic activity loss of traditional photocatalysts when the light illumination is turned off.Due to the dual requirements of light absorption and energy storage/release functions,most previously reported photocatalysts with the photocatalytic'memory'effect were composite photocatalysts of two phase components,which may lose their performance due to gradually deteriorated interface conditions during their applications.In this work,a simple solvothermal process was developed to synthesize Bi2WO6 microspheres constructed by aggregated nanoflakes.The pure phase Bi_(2)WO_(6) was found to possess the photocatalytic'memory'effect through the trapping and release of photogenerated electrons by the reversible chemical state change of W component in the(WO_(4))^(2–)layers.When the illumination was switched off,Bi_(2)WO_(6) microspheres continuously produced H_(2)O_(2) in the dark as those trapped photogenerated electrons were gradually released to react with O_(2) through the two-electron O_(2) reduction process,resulting in the continuous disinfection of Escherichia coli bacteria in the dark through the photocatalytic'memory'effect.No deterioration of their cycling H2O2 production performance in the dark was observed,which verified their stable photocatalytic'memory'effect. | Weiyi Yang Yan Chen Shuang Gao Licheng Sang Ruoge Tao Caixia Sun Jian Ku Shang Qi Li | 2021 | Journal of Advanced Ceramics2021，10，2： | 1 |

| 19 | Biomechanical evaluation of two fusion techniques based on finite element analysis:Percutaneous endoscopic and minimally invasive transforaminal lumbar interbody fusion显示文摘As a novel minimally invasive technique,percutaneous endoscopic transforaminal lumbar interbody fusion(PETLIF)has been widely used in the treatment of lumbar degenerative diseases.The purpose of this study was to analyze these two operation types’biomechanical performances of PE-TLIF and traditional minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF)using the finite element(FE)method.The intact FE models of L4-L5 were established and validated based on the CT images.On this basis,the FE models of MIS-TLIF and PETLIF were established and analyzed.It is demonstrated that for lumbar interbody fusion with the oblique asymmetrically implanted cage under bilateral pedicle screws and rods fixation,such as MIS-TLIF and PE-TLIF,different degrees of articular process resection have no significant effect on the cage subsidence,and the surgical segment can achieve similar stability.In addition,the maximum stress of the L4 inferior endplate of MIS-TLIF and PE-TLIF is greater than that of the L5 superior endplate,which indicates that MIS-TLIF and PE-TLIF can cause cage subsidence in the L4 inferior endplate. | Yang Yan Jiarui Li Jianhao Yu Yan Wang Hao Dong Yuqin Sun Xiaogang Wu Liming He Weiyi Chen Haoyu Feng | 2022 | Medicine in Novel Technology and Devices2022，，4： | 1 |
| 20 | Intravenous route to choroidal neovascularization by macrophage-disguised nanocarriers for mTOR modulation显示文摘Retinal pigment epithelial(RPE) is primarily impaired in age-related macular degeneration(AMD), leading to progressive loss of photoreceptors and sometimes choroidal neovascularization(CNV). mTOR has been proposed as a promising therapeutic target, while the usage of its specific inhibitor,rapamycin, was greatly limited. To mediate the mTOR pathway in the retina by a noninvasive approach, we developed novel biomimetic nanocomplexes where rapamycin-loaded nanoparticles were coated with cell membrane derived from macrophages(termed as MRaNPs). Taking advantage of the macrophage-inherited property, intravenous injection of MRaNPs exhibited significantly enhanced accumulation in the CNV lesions, thereby increasing the local concentration of rapamycin. Consequently, MRaNPs effectively downregulated the mTOR pathway and attenuate angiogenesis in the eye. Particularly, MRaNPs also efficiently activated autophagy in the RPE, which was acknowledged to rescue RPE in response to deleterious stimuli. Overall, we design and prepare macrophage-disguised rapamycin nanocarriers and demonstrate the therapeutic advantages of employing biomimetic cell membrane materials for treatment of AMD. | Weiyi Xia Chao Li Qinjun Chen Jiancheng Huang Zhenhao Zhao Peixin Liu Kai Xu Lei Li Fangyuan Hu Shujie Zhang Tao Sun Chen Jiang Chen Zhao | 2022 | Acta Pharmaceutica Sinica B2022，12，5： | 1 |
