1Effect of ultrasonic treatment and Sr addition on microstructure of Al-20%Si alloy显示文摘Many investigations have revealed that transition of melt structure can effectively infl uence the fi nal solidifi cation microstructures.In this study,ultrasonic treatment was applied to Al-20%Si melt and Sr-modif ied Al-20%Si melt at 720℃(i.e.above liquidus of about 690℃)for 60 s,and then the melt was quickly quenched to room temperature.Experimental results show that ultrasonic treatment can ref ine the primary Si phase andα-Al of Al-20%Si alloy;strontium can make the morphology of Si phase spheroidized and refi ned as Sr addition changes the faceted growth characteristic of Si phase;however,the ref inement effect of ultrasonic treatment on the primary Si phase andα-Al is weakened by Sr addition.Miao Long Lu Yiping Zhang Yubo Fu Ying Li Tingju 2013China Foundry2013,10,4:10
2A NAC transcription factor, NOR-like1, is a new positive regulator of tomato fruit ripening显示文摘Ripening of the model fruit tomato(Solanum lycopersicum)is controlled by a transcription factor network including NAC(NAM,ATAF1/2,and CUC2)domain proteins such as No-ripening(NOR),SlNAC1,and SlNAC4,but very little is known about the NAC targets or how they regulate ripening.Here,we conducted a systematic search of fruit-expressed NAC genes and showed that silencing NOR-like1(Solyc07g063420)using virus-induced gene silencing(VIGS)inhibited specific aspects of ripening.Ripening initiation was delayed by 14 days when NOR-like1 function was inactivated by CRISPR/Cas9 and fruits showed obviously reduced ethylene production,retarded softening and chlorophyll loss,and reduced lycopene accumulation.RNA-sequencing profiling and gene promoter analysis suggested that genes involved in ethylene biosynthesis(SlACS2,SlACS4),color formation(SlGgpps2,SlSGR1),and cell wall metabolism(SlPG2a,SlPL,SlCEL2,and SlEXP1)are direct targets of NOR-like1.Electrophoretic mobility shift assays(EMSA),chromatin immunoprecipitation-quantitative PCR(ChIP-qPCR),and dual-luciferase reporter assay(DLR)confirmed that NOR-like1 bound to the promoters of these genes both in vitro and in vivo,and activated their expression.Our findings demonstrate that NOR-like1 is a new positive regulator of tomato fruit ripening,with an important role in the transcriptional regulatory network.Ying Gao Wei Wei Xiaodan Zhao Xiaoli Tan Zhongqi Fan Yiping Zhang Yuan Jing Lanhuan Meng Benzhong Zhu Hongliang Zhu Jianye Chen Cai-Zhong Jiang Donald Grierson Yunbo Luo Da-Qi Fu 2018Horticulture Research2018,5,1:9
3Wheat genomic study for genetic improvement of traits in China显示文摘Bread wheat(Triticum aestivum L.)is a major crop that feeds 40%of the world’s population.Over the past several decades,advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat,and the genetic basis of agronomically important traits,which promote the breeding of elite varieties.In this review,we focus on progress that has been made in genomic research and genetic improvement of traits such as grain yield,end-use traits,flowering regulation,nutrient use efficiency,and biotic and abiotic stress responses,and various breeding strategies that contributed mainly by Chinese scientists.Functional genomic research in wheat is entering a new era with the availability of multiple reference wheat genome assemblies and the development of cutting-edge technologies such as precise genome editing tools,highthroughput phenotyping platforms,sequencing-based cloning strategies,high-efficiency genetic transformation systems,and speed-breeding facilities.These insights will further extend our understanding of the molecular mechanisms and regulatory networks underlying agronomic traits and facilitate the breeding process,ultimately contributing to more sustainable agriculture in China and throughout the world.Jun Xiao Bao Liu Yingyin Yao Zifeng Guo Haiyan Jia Lingrang Kong Aimin Zhang Wujun Ma Zhongfu Ni Shengbao Xu Fei Lu Yuannian Jiao Wuyun Yang Xuelei Lin Silong Sun Zefu Lu Lifeng Gao Guangyao Zhao Shuanghe Cao Qian Chen Kunpu Zhang Mengcheng Wang Meng Wang Zhaorong Hu Weilong Guo Guoqiang Li Xin Ma Junming Li Fangpu Han Xiangdong Fu Zhengqiang Ma Daowen Wang Xueyong Zhang Hong-Qing Ling Guangmin Xia Yiping Tong Zhiyong Liu Zhonghu He Jizeng Jia Kang Chong 2022Science China(Life Sciences)2022,65,9:9

5Study of ultrahigh-purity copper billets refined by vacuum melting and directional solidification显示文摘The purpose of this paper is to study large-sized copper billets refined with 5N ultrahigh purity after vacuum melting and directional solidifi-cation (VMDS). The precise impurity analysis of copper billets was carried out with a glow discharge mass spectrometer (GDMS). The re-sults demonstrate that the total concentration of twenty-two impurities is decreased by 63.1wt.%-66.5 wt.%. Ag, P, S, Na, Mg, Se, Zn, In and Bi are easy to be removed due to lgPimp - lgPCu > 1.5, and they can be removed effectively under the vacuum condition of 1650-1700 K for 30 min. The electrical conductivity of 5N copper is higher than that of the raw material as the impurity concentrations decrease. The segrega-tion effect in directional solidification can be remarkable when the equilibrium distribution coefficient (k0) value is less than 0.65 due to the strong affinity of Cu for some metallic and non-metallic impurities.FU Yabo CHEN Jie LIU Ning LU Yiping LI Tingju YIN Guomao 2011Rare Metals2011,30,3:6
6Origin of strong solid solution strengthening in the CrCoNi-W medium entropy alloy显示文摘Solid solution strengthening is one of the most conventional strategies for optimizing alloys strength,while the corresponding mechanisms can be more complicated than we traditionally thought specifically as heterogeneity of microstructure is involved.In this work,by comparing the change of chemical distribution,dislocation behaviors and mechanical properties after doping equivalent amount of tungsten(W)atoms in CrCoNi alloy and pure Ni,respectively,it is found that the alloying element W in CrCoNi alloy resulted in much stronger strengthening effect due to the significant increase of heterogeneity in chemical distribution after doping trace amount of W.The large atomic scale concentration fluctuation of all elements in CrCoNi-3W causes dislocation motion via strong nanoscale segment detrapping and severe dislocation pile up which is not the case in Ni-3W.The results revealed the high sensitivity of elements distribution in multi-principle element alloys to composition and the significant consequent influence in tuning the mechanical properties,giving insight for complex alloy design.Yujie Chen Yan Fang Xiaoqian Fu Yiping Lu Sijing Chen Hongbin Bei Qian Yu 2021Journal of Materials Science & Technology2021,,14:5
7Ductile and ultrahigh-strength eutectic high-entropy alloys by large-volume 3D printing显示文摘1.Introduction Additive manufacturing or 3D printing outweighs conventional casting methods in the aspect of complex parts fabrication,which can realize one-step formation without the need of complicated cast dies.3D printing significantly promotes industrial production for making near-net shaped components.However,this promising technique is not always ideally applicable for metals and alloys.For example,titanium alloys prepared by 3D printing often suf-fer from poor plasticity,and usually require further complex heat treatment or hot isostatic pressing treatment,in order to remove internal stress and regulate plasticity and strength[1,2],which de-feats the original intention of employing additive manufacturing.One of the fundamental causes for such issues is the low fluidity of the alloys upon melting,leading to great chemical heterogeneity,high porosity content and residual stresses.This limitation hinders further design and fabrication of high-performance printable alloys from large scale production and application.Yiping Lu Xiaoxiang Wu Zhenghong Fu Qiankun Yang Yong Zhang Qiming Liu Tianxin Li Yanzhong Tian Hua Tan Zhiming Li Tongmin Wang Tingju Li 2022Journal of Materials Science & Technology2022,,31:4

9Effect of pyrophosphate on the light scatter in KDP crystal显示文摘Pyrophosphate doped potassium dihydrogen phosphate (KDP) crystal was grown from aqueous solution by the temperature lowering method. Light scatter in KDP crystal was detected with the ultramicroscopic method. The light scatter in KDP crystal was aggravated when pyro-phosphate was doped into the growth solution, which was distributed ununiformly in prism and pyramidal sectors of KDP crystal. Different effects of pyrophosphate on prism and pyramidal sectors of KDP crystal can explain this case. The transmission in this crystal was measured, showing that pyrophosphate affects the transmission evidently.Xun Sun Xinguang Xu Youjun Fu Shenglai Wang Hong Zeng Yiping Li Zhangshou Gao 2001Chinese Science Bulletin2001,46,5:3

15A fast auto-focusing method of microscopic imaging based on an improved MCS algorithm显示文摘An improved'three steps'mountain-climb searching(MCS)algorithm is proposed which is applied to auto-focusing for microscopic imaging accurately and efficiently.By analyzing the performance of several evaluation functions,the variance function and the Brenner function are synthesized as a new evaluation function.In the first step,a self-adaptive step length which is much dependent on the reciprocal of the evaluation function value at the beginning position of climbing is used for approaching the halfway up the mountain roughly.Secondly,a fixed moderate step length is applied for approaching the mountaintop of the variance function as closer as possible.Finally,afine step is employed for reaching the exact mountaintop of the Brenner function.The microscope auto-focusing experiments based on the proposed algorithm for blood smear detection have been carried out comprehensively.The results show that the improved algorithm can not only guarantee the precision to get clear focal images,but also improve the auto-focusing e±ciency.Guangkai Fu Yiping Cao Mingteng Lu 2015Journal of Innovative Optical Health Sciences2015,8,5:1

17A counting method for complex overlapping erythrocytes-based microscopic imaging显示文摘Red blood cell(RBC)counting is a standard medical test that can help diagnose various conditions and diseases.Manual counting of blood cells is highly tedious and time consuming.However,new methods for counting blood cells are customary employing both electronic and computer-assisted techniques.Image segmentation is a classical task in most image processing applications which can be used to count blood cells in a microscopic image.In this research work,an approach for erythrocytes counting is proposed.We employed a classification before counting and a new segmentation idea was implemented on the complex overlapping clusters in a microscopic smear image.Experimental results show that the proposed method is of higher counting accuracy and it performs much better than most counting algorithms existed in the situation of three or more RBCs overlapping complexly into a group.The average total erythrocytes counting accuracy of the proposed method reaches 92.9%.Xudong Wei Yiping Cao Guangkai Fu Yapin Wang 2015Journal of Innovative Optical Health Sciences2015,8,6:1

20The BZR1-EDS1 module regulates plant growth-defense coordination显示文摘Plants have developed sophisticated strategies to coordinate growth and immunity,but our understanding of the underlying mechanism remains limited.In this study,we identified a novel molecular module that reg-ulates plant growth and defense in both compatible and incompatible infections.This module consisted of BZR1,a key transcription factor in brassinosteroid(BR)signaling,and EDS1,an essential positive regulator of plant innate immunity.We found that EDS1 interacts with BZR1 and suppresses its transcriptional activ-ities.Consistently,upregulation of EDS1 function by a virulent Pseudomonas syringae strain or salicylic acid treatment inhibited BZR1-regulated expression of BR-responsive genes and BR-promoted growth.Furthermore,we showed that the cytoplasmic fraction of BZR1 positively regulates effector-triggered im-munity(ETI)controlled by the TIR-NB-LRR protein RPS4,which is attenuated by BZR1's nuclear transloca-tion.Mechanistically,cytoplasmic BZR1 facilitated AvrRps4-triggered dissociation of EDS1 and RPS4 by binding to EDS1,thus leading to efficient activation of RPS4-controlled ETI.Notably,transgenic expression of a mutant BZR1 that accumulates exclusively in the cytoplasm improved pathogen resistance without compromising plant growth.Collectively,these results shed new light on plant growth-defense coordina-tion and reveal a previously unknown function for the cytoplasmic fraction of BZR1.The BZR1-EDS1 mod-ule may be harnessed for the simultaneous improvement of crop productivity and pathogen resistance.Guang Qi Huan Chen Dian Wang Hongyuan Zheng Xianfeng Tang Zhengzheng Guo Jiayu Cheng Jian Chen Yiping Wang Ming-yi Bai Fengquan Liu Daowen Wang Zheng Qing Fu 2021Molecular Plant2021,14,12:1
