| 2 | Characterizations and mechanical properties of impregnated diamond segment using Cu-Fe-Co metal matrix显示文摘Diamond impregnated Cu-Fe-Co based saw-blade segments are directly processed by vacuum and pressure-assisted sintering at different temperature,with the purpose of reducing the cobalt content in diamond tools.Copper and iron are used as the bonding elements and co-balt-chrome pre-alloyed powder is used as the hardening phase.Effects of sintering temperature on microstructures and mechanical properties of the sintered matrix and diamond graphitization were investigated by X-ray diffraction analysis,electron probe micro-analyzer,universal testing machine,digital Rockwell hardness tester and Raman scattering analyzer.Results showed that microstructures of the sintered matrix were refined and porosities in the sintered matrix were closed to a more spherical-like shape with the increase of the sintering temperature.Densification,hardness and tensile strength of the matrix sintered at 820 ℃ were 12.75%,2.72% and 156.38% higher than that of the matrix sintered at 740 ℃,respectively.Diamond graphitization was not occurred at 820 ℃.The hardness and the tensile strength rose 32.8% and 13.5%,respectively,after 7.5 h ageing treatment.The matrix densification ascent and the dispersed distribution of Co-Cr pre-alloyed powders contributed a hardness improvement and a tensile strength improvement to the Cu-Fe based matrix. | Li, Wensheng Zhang, Jie Wang, Shucai Dong, Hongfeng Li, Yaming Liu, Yi | 2012 | Rare Metals2012，31，1： | 19 |
| 3 | Numerical Calculation and Experimental Research on Residual Stresses in Precipitation-hardening Layer of NAK80 Steel for Shot Peening显示文摘Shot peening can improve fatigue strength of materials by creating compressive residual stress field in their surface layers,and offers a protection against crack initiation and propagation,corrosion,etc.And fatigue fracture and stress corrosion cracking of NAK80 steel parts are improved effectively.Currently there lacks in-depth research in which the beneficial effect of the residual stress may be offset by the surface damage associated with shot peening,especially in terms of the research on the effective control of shot peening intensity.In order to obtain the surface residual stress field of NAK80 steel after shot peening,the samples are shot peened by pneumatic shot peening machine with different rules.The residual stress in the precipitation-hardening layer of NAK80 steel is measured before and after a shot peening treatment by X-ray diffraction method.In order to obtain true residual stress field,integral compensation method is used to correct results.By setting up analytical model of the residual stress in the process of shot peening,the surface residual stress is calculated after shot peening,and mentioning the reason of errors occurred between calculated and experimental residual stresses,which is mainly caused by the measurement error of the shoot arc height.At the same time,micro hardness,microstructure and roughness in the precipitation-hardening layer of NAK80 steel before and after shot peening were measured and surveyed in order to obtain the relation between shot peening strength and surface quality in the precipitation-hardening layer.The results show that the surface quality of NAK80 steel is significantly improved by shot peening process.The over peening effect is produced when the shot peening intensity is too high,it is disadvantageous to improve sample's surface integrity,and leading to reduce the fatigue life.When arc high value of optimal shot peening is 0.40 mm,the surface quality is the best,and the depth of residual stress in the precipitation-hardening layer reaches to about 450 μm.Numerical calculation is very useful to define the process parameters when a specific residual stress profile is intended,either to quantify the benefits on a specific property like fatigue life or to help on modeling a forming process like shot peen forming.In particular,the proposed parameter optimization in the progress of shot peening and effective control of the surface texture provide new rules for the quantitative evaluations of shot peening surface modification of NAK80 steel. | MIAO Hong ZUO Dunwen WANG Min ZHANG Ruihong WANG Hongfeng | 2011 | Chinese Journal of Mechanical Engineering2011，24，3： | 17 |
| 4 | Full-thickness tissue engineered skin constructed with autogenic bone marrow mesenchymal stem cells显示文摘To explore the feasibility of repairing clinical cutaneous deficiency, autogenic bone marrow mesen-chymal stem cells (BMSCs) were isolated and differentiated into epidermal cells and fibroblasts in vitro supplemented with different inducing factors and biomaterials to construct functional tissue- engineered skin. The results showed that after 72 h induction, BMSCs displayed morphologic changes such as typical epidermal cell arrangement, from spindle shape to round or oval; tonofibrils, melano-somes and keratohyaline granules were observed under a transmission electronic microscope. The differentiated cells expressed epidermal stem cell surface marker CK19 (59.66% ± 4.2%) and epidermal cells differentiation marker CK10. In addition, the induced epidermal cells acquired the anti-radiation capacity featured by lowered apoptosis following exposure to UVB. On the other hand, the collagen microfibrils deposition was noticed under a transmission electronic microscope after differentiating into dermis fibroblasts; RT-PCR identified collagen type I mRNA expression in differentiated cells; radioimmunoassay detected the secretion of interleukin-6 (IL-6) and interleukin-8 (IL-8) (up to 115.06 pg/mL and 0.84 ng/mL, respectively). Further in vivo implanting BMSCs with scaffold material short-ened skin wound repair significantly. In one word, autogenic BMSCs have the potential to differentiate into epidermal cells and fibroblasts in vitro, and show clinical feasibility acting as epidermis-like and dermis-like seed cells in skin engineering. | HE LiJuan, NAN Xue, WANG YunFang, GUAN LiDong, BAI CiXian, SHI ShuangShuang, YUAN HongFeng, CHEN Lin, LIU DaQing & PEI XueTao Laboratory of Stem Cells and Regenerative Medicine, Institute of Blood Transfusion, Academy of Military Medical Sciences, Beijing 100850, China | 2007 | Science China(Life Sciences)2007，50，4： | 16 |
| 5 | Rapid report of the 8 January 2022 M_(S)6.9 Menyuan earthquake,Qinghai,China显示文摘The M_(S)6.9 Menyuan earthquake in Qinghai Province,west China is the largest earthquake by far in 2022.The earthquake occurs in a tectonically active region,with a background b-value of 0.87 within 100 km of the epicenter that we derived from the unified catalog produced by China Earthquake Networks Center since late 2008.Field surveys have revealed surface ruptures extending 22 km along strike,with a maximum ground displacement of 2.1 m.We construct a finite fault model with constraints from In SAR observations,which showed multiple fault segments during the Menyuan earthquake.The major slip asperity is confined within 10 km at depth,with the maximum slip of 3.5 m.Near real-time back-projection results of coseismic radiation indicate a northwest propagating rupture that lasted for~10 s.Intensity estimates from the back-projection results show up to a Mercalli scale of IX near the ruptured area,consistent with instrumental measurements and the observations from the field surveys.Aftershock locations(up to January 21,2022)exhibit two segments,extending to~20 km in depth.The largest one reaches M_(S)5.3,locating near the eastern end of the aftershock zone.Although the location and the approximate magnitude of the mainshock had been indicated by previous studies based on paleoearthquake records and seismic gap,as well as estimated stressing rate on faults,significant surfacebreaching rupture leads to severe damage of the high-speed railway system,which poses a challenge in accurately assessing earthquake hazards and risks,and thus demands further investigations of the rupture behaviors for crustal earthquakes. | Hongfeng Yang Dun Wang Rumeng Guo Mengyu Xie Yang Zang Yue Wang Qiang Yao Chuang Cheng Yanru An Yingying Zhang | 2022 | Earthquake Research Advances2022，2，1： | 14 |

| 7 | Resequencing of 145 Landmark Cultivars Reveals Asymmetric Sub-genome Selection and Strong Founder Genotype Effects on Wheat Breeding in China显示文摘Controlled pedigrees and the multi-decade timescale of national crop plant breeding programs offer a unique experimental context for examining how selection affects plant genomes.More than 3000 wheat cultivars have been registered,released,and documented since 1949 in China.In this study,a set of 145 elite cultivars selected from historical points of wheat breeding in China were re-sequenced.A total of 43.75 Tb of sequence data were generated with an average read depth of 17.94x for each cultivar,and more than 60.92 million SNPs and 2.54 million InDels were captured,based on the Chinese Spring RefSeq genome v1.0.Seventy years of breeder-driven selection led to dramatic changes in grain yield and related phenotypes,with distinct genomic regions and phenotypes tar-geted by different breeders across the decades.There are very clear instances illustrating how introduced Italian and otherforeign germplasm was integrated into Chinese wheat programs and reshaped the genomic landscape of local modern cultivars.Importantly,the resequencing data also highlighted significant asymmetric breeding selec-tion among the three sub-genomes:this was evident in both the collinear blocks for homeologous chromosomes and among sets of three homeologous genes.Accumulation of more newly assembled genes in newer cultivars implied the potential value of these genes in breeding.Conserved and extended sharing of linkage disequilibrium(LD)blocks was highlighted among pedigree-related cultivars,in which fewer haplotype differences were detected.Fixation or replacement of haplotypes from founder genotypes after generations of breeding was related to their breeding value.Based on the haplotype frequency changes in LD blocks of pedigree-related cultivars,we propose a strategy for evaluating the breeding value of any given line on the basis of the accumulation(pyramiding)of bene-ficial haplotypes.Collectively,our study demonstrates the influence of 'founder genotypes' on the output of breeding efforts over many decades and also suggests that founder genotype perspectives are in fact more dy-namic when applied in the context of modern genomics-informed breeding. | Chenyang Hao Chengzhi Jiao Jian Hou Tian Li Hongxia Liu Yuquan Wang Jun Zheng Hong Liu Zhihong Bi Fengfeng Xu Jing Zhao Lin Ma Yamei Wang Uzma Majeed Xu Liu Rudi Appels Marco Maccaferri Roberto Tuberosa Hongfeng Lu Xueyong Zhang | 2020 | Molecular Plant2020，13，12： | 9 |
| 8 | RESUSPENSION METHOD FOR ROAD SURFACE DUST COLLECTION AND AERODYNAMIC SIZE DISTRIBUTION CHARACTERIZATION显示文摘Traffic-generated fugitive dust is a source of urban atmospheric particulate pollution in Beijing. This paper introduces the resuspension method, recommended by the US EPA in AP-42 documents, for collecting Beijing road-surface dust. Analysis shows a single-peak distribution in the number size distribution and a double-peak mode for mass size distribution of the road surface dust. The median diameter of the mass concentration distribution of the road dust on a high-grade road was higher than that on a low-grade road. The ratio of PM2.5 to PM10 was consistent with that obtained in a similar study for Hong Kong. For the two selected road samples, the average relative deviation of the size distribution was 10.9% and 11.9%. All results indicate that the method introduced in this paper can effectively determine the size distribution of fugitive dust from traffic. | Jianhua Chen Hongfeng Zheng Wei Wang Hongjie Liu Ling Lu Linfa Bao Lihong Ren | 2006 | China Particuology2006，4，6： | 7 |

| 10 | Elemental sulfur in northern South China Sea sediments and its significance显示文摘Elemental sulfur(ES) is one of the intermediates in the inorganic sulfur cycle and thus plays a key role in the fractionation of stable sulfur isotopes in different reservoirs and the marine environment. In this study, solid ES is discovered in sediments near the Jiulong Methane Reef in the northern South China Sea by scanning electron microscopy and Raman spectroscopy. Combining the morphology and distribution of ES, pyrite concentrations, and sulfur isotopes, we conclude that:(1) solid ES coexists with pyrite microcrystals and sulfide(oxyhydr)oxides as well as clay minerals, and they are mainly distributed on the surface of mineral aggregates;(2) ES mainly occurs within and near the sulfate-methane transition zone(SMTZ) despite little morphological diversity;(3) ES formation might be related to hydrogen sulfide oxidation and is therefore linked with fluctuations in the SMTZ. Within the SMTZ, hydrogen sulfide is produced and pyrite precipitates because of enhanced anaerobic oxidation of methane coupled with dissimilatory sulfate reduction. This enhances the efficiency of the inorganic sulfur cycle and provides favorable conditions for ES formation. The discovery of solid ES in sediments near the Jiulong Methane Reef suggests an important relationship with SMTZ fluctuations that could have implications for the evolution of methane hydrate in the South China Sea. | LIN Qi WANG JiaSheng FU ShaoYing LU HongFeng BU QingTao LIN RongXiao SUN Fei | 2015 | Science China Earth Sciences2015，58，12： | 6 |
| 11 | A review of friction stir joining of SiCp/Al composites显示文摘SiCp/Al composites have excellent comprehensive properties and have been widely used in aerospace,automotive industry and other fields.Due to the huge difference in performance between SiC particles and matrix alloys,traditional fusion welding methods are difficult to meet the join requirements of SiCp/Al composites.Friction stir joining(friction stir welding),as a solid phase joining process,has been proved to be a new technology with fine prospect in joining SiCp/Al composites compared with fusion welding process.Although some progress has been made in recent years,there are still full of challenges.In this paper,the research status of friction stir joining of SiCp/Al composites in recent years is expatiated,including the weldability of SiCp/Al composites,the macrostructure and the microstructure of joints,mechanical properties of joints,and tool wear and monitoring.Furthermore,the existing challenges of friction stir joining of SiCp/Al composites are summarized and the future development directions are prospected. | Lisheng ZUO Xianrui ZHAO Zeyang LI Dunwen ZUO Hongfeng WANG | 2020 | Chinese Journal of Aeronautics2020，33，3： | 6 |
| 12 | Noble Gas Isotopic Compositions of Cobalt-rich Ferromanganese Crusts from the Western Pacific Ocean and Their Geological Implications显示文摘Noble gas isotopic compositions of various layers in three-layered (outer, porous and compact layers) cobalt-rich ferromanganese crusts and their basaltic and phosphorite substrates from the western Pacific Ocean were analyzed by using a high vacuum gas mass spectrum. The analytical results show that the noble gases in the Co-rich crusts have derived mainly from the ambient seawater, extraterrestrial grains such as interplanetary dust particles (IDPs) and wind-borne continental dust grains, and locally formation water in the submarine sediments, but different noble gases have different sources. He in the crusts derives predominantly from the extraterrestrial grains, with a negligible amount of radiogenic He from the eolian dust grains. Ar is sourced mainly from the dissolved air in the seawater and insignificantly from radiogenic Ar in the eolian continental dust grains or the formation water. Xe and Ne derive mainly from the seawater, with minor amounts of extraterrestrial Xe and Ne in the IDPs. Compared with the porous and outer layers, the compact layer has a relatively high 4He content and lower 3He/4He ratios, suggesting that marine phosphatization might have greatly modified the noble gas isotopic compositions of the crusts. Besides, the 3He/4He values of the basaltic substrates of the cobalt-rich crusts are very low and their R/Ra ratios are mostly <0.1 Ra, which are similar to that of phosphorite substrates (0.087 Ra), but much lower than that of fresh submarine MORB (8.75±2.14 Ra) or seamount basalts (3-43 Ra), implying that the basaltic substrates have suffered strong water/rock interaction and reacted with radiogenic 4He and P-rich upwelling marine currents during phosphatization. The trace elements released in the basalt/seawater interaction might favor the growth of cobalt-rich crusts. The relatively low 3He/4He values in the seamount basalts may be used as an important exploration criterion for the cobalt-rich ferromanganese crusts. | SUN Xiaoming XUE Ting HE Gaowen YE Xianren ZHANG Mei LU Hongfeng WANG Shengwei | 2007 | Acta Geologica Sinica(English Edition)2007，81，1： | 5 |
| 13 | Thermogravimetric study of the effect of a PVA oxygen-insulating barrier on the spontaneous combustion of coal显示文摘Coal samples in the air for three months were characterized by Thermogravimetric Analysis (TGA). The effect of a PVA oxygen-insulating barrier on the spontaneous combustion of coal was examined. The moisture loss activation energy, oxidation activation energy and combustion activation energy were calculated by an integral method using the Coats-Redfen formula. The results show that the tendency for spontaneous combustion of three coal samples (judged by the activation energy) falls in the order: CYW>YJL>SW. The oxidation activation energy and combustion activation energy of coal protected by the PVA oxygen-insulating barrier increased. A significant increase in the combustion activation energy was noted, especially for the CYW coal where the in-crease was 28.53 kJ/mol. Hence, oxidation of the protected coal samples was more difficult. The PVA oxygen-insulating barrier helps to prevent spontaneous combustion of the coal. | MENG Xianhang CHU Ruizhi WU Guoguang XU Hongfeng ZHU Jiamei WANG Zhihua | 2010 | Mining Science and Technology2010，20，6： | 5 |
| 14 | Devonian Sequence Stratigraphy and Relative Sea Level Changes in Longmenshan Area, Sichuan显示文摘The Longmenshan area is located at the western margin of Yangtze platform, where the Devonian is composed of clastic rocks, mixed clastic-carbonate rocks and carbonate rocks in ascending order, and was formed in the marine environment from nearshore to outer shelf. Based on a study of six sections the Devonian in Longemenshan area is divided into 18 sequences and 5 sequence sets. The maximum transgressive high in the Devonian of this area occurred in Early Frasnian, corresponding to asymmetricus zone. The boundaries among the sequence sets are roughly corresponding to the bottom boundaries of Ⅰa’,Ⅰc’,Ⅱa, and Ⅱd in the Devonian of West Europe and North America, respectively. The frequencies of the relative sea level changes in this area vary in different periods, but can be correlated with those in the other regions of the world. | Liu Wenjun Chen Yuanren Zheng Rongcai Wang Hongfeng Li Xianghui (Chengdu Institute of Technology, Chengdu 610059) | 1996 | Journal of Earth Science1996，15，1： | 5 |
| 15 | Less and shrunken pollen 1(LSP1) encodes a member of the ABC transporter family required for pollen wall development in rice(Oryza sativa L.)显示文摘Pollen fertility is an agronomic trait that strongly influences rice yield. Recent studies have revealed that the development of the pollen wall is required for pollen fertility and is regulated by several genes. However, the mechanisms underlying pollen and pollen wall development in rice remain largely unknown. In the present study, a point mutation in a gene on chromosome 1 was identified that resulted in the production of less and shrunken pollen(LSP) and led to defects in pollen wall formation. This gene was named LSP1 and was found to encode a member of the adenosine triphosphate-binding cassette(ABC)transporter G subfamily, OsABCG3. Two other loss-of-function mutants of LSP1/OsABCG3,generated using CRISPR/Cas9 technology, showed the same male sterile phenotype. The LSP1/OsABCG3 gene showed a spatio-temporal expression pattern in the developing anthers, and is an ortholog of the Arabidopsis genes At ABCG1 and At ABCG16, which play an important role in pollen wall development. Mutation of LSP1/OsABCG3 affected the expression of several genes involved in pollen and pollen wall formation. These results suggest that LSP1/OsABCG3 is critical for normal pollen fertility and shed light on the molecular mechanisms underlying rice pollen wall development. | Tao Luo Ting Zou Guoqiang Yuan Zhiyuan He Wenjie Li Yang Tao Miaomiao Liu Dan Zhou Hongfeng Zhao Jun Zhu Yueyang Liang Qiming Deng Shiquan Wang Aiping Zheng Huainian Liu Lingxia Wang Ping Li Shuangcheng Li | 2020 | The Crop Journal2020，8，3： | 4 |
| 16 | Wheat breeding history reveals synergistic selection of pleiotropic genomic sites for plant architecture and grain yield显示文摘Diversity surveys of crop germplasm are important for gaining insights into the genomic basis for plant architecture and grain yield improvement,which is still poorly understood in wheat.In this study,we exome sequenced 287 wheat accessions that were collected in the past 100 years.Population genetics analysis identified that 6.7%of the wheat genome falls within the selective sweeps between landraces and cultivars,which harbors the genes known for yield improvement.These regions were asymmetrically distributed on the A and B subgenomes with regulatory genes being favorably selected.Genome-wide association study(GWAS)identified genomic loci associated with traits for yield potential,and two underlying genes,TaARF12 encoding an auxin response factor and TaDEP1 encoding the G-proteinγ-subunit,were located and characterized to pleiotropically regulate both plant height and grain weight.Elite single-nucleotide haplotypes with increased allele frequency in cultivars relative to the landraces were identified and found to have accumulated over the course of breeding.Interestingly,we found that TaARF12 and TaDEP1 function in epistasis with the classical plant height Rht-1 locus,leading to propose a“Green Revolution”-based working model for historical wheat breeding.Collectively,our study identifies selection signatures that fine-tune the gibberellin pathway during modern wheat breeding and provides a wealth of genomic diversity resources for the wheat research community. | Aili Li Chenyang Hao Zhenyu Wang Shuaifeng Geng Meiling Jia Fang Wang Xiang Han Xingchen Kong Lingjie Yin Shu Tao Zhongyin Deng Ruyi Liao Guoliang Sun Ke Wang Xingguo Ye Chengzhi Jiao Hongfeng Lu Yun Zhou Dengcai Liu Xiangdong Fu Xueyong Zhang Long Mao | 2022 | Molecular Plant2022，15，3： | 4 |
| 17 | Radioactivity monitoring in environmental water and air around QNPP显示文摘Results of environmental radioactivity monitoring around Qinshan Nuclear Power Plant (QNPP) are reported in this paper. From 1992 to 2005, concentrations of 90Sr, 137Cs and 3H in terrestrial freshwater are (4.4±1.7) mBq·L-1, (0.3±0.1) mBq·L-1 and (1.6±0.5) Bq·L-1, respectively, and (2.8±2.4) Bq·L-1 of 3H in rainwater. Concentrations of 90Sr, 137Cs and 3H in the seawater samples collected from sea area nearby QNPP are (5.4±4.1) mBq·L-1, (0.7±0.2) mBq·L-1 and (1.0±0.5) Bq·L-1, respectively. Concentrations of 90Sr, 137Cs and 3H in the total waste water discharged from NPP-I are (4.0±1.8) m Bq·L-1, (1.0±0.5) mBq·L-1 and (2.8±2.2) Bq·L-1, respectively, and (1.4±0.4) Bq·L-1 of 3H in seawater sampled from No.1 outlet. Atomspheric 3H concentration in 1993~2005 at two monitoring sites is (78.9±96.3) and (64.2±40.2) mBq·m-3, respectively, with an increasing trend after 2003. Atmospheric 14C concentrations at the two sites are in the same levels as the background and data of the reference site. | XIANG Yuanyi WANG Kan ZHANG Yu CAO Zhonggang YE Jida WANG Hongfeng | 2007 | Nuclear Science and Techniques2007，18，5： | 4 |
| 18 | The nodulation and nyctinastic leaf movement is orchestrated by clock gene LHY in Medicago truncatula显示文摘As sessile organisms,plants perceive,respond,and adapt to the environmental changes for optimal growth and survival.The plant growth and fitness are enhanced by circadian clocks through coordination of numerous biological events.In legume species,nitrogen-fixing root nodules were developed as the plant organs specialized for symbiotic transfer of ni-trogen between microsymbiont and host.Here,we report that the endogenous circadian rhythm in nodules is regulated by MtLHY in legume species Medicago truncatula.Loss of function of MtLHY leads to a reduction in the number of nodules formed,resulting in a diminished ability to assimilate nitrogen.The operation of the 24-h rhythm in shoot is further influenced by the availability of nitrogen produced by the nodules,leading to the irregulated nyctinastic leaf movement and reduced biomass in mtlhy mutants.These data shed new light on the roles of MtLHY in the orchestration of circadian oscillator in nodules and shoots,which provides a mechanistic link between nodulation,nitrogen assimilation,and clock function. | Yiming Kong Lu Han Xiu Liu Hongfeng Wang Lizhu Wen Xiaolin Yu Xiaodong Xu Fanjiang Kong Chunxiang Fu Kirankumar S.Mysore Jiangqi Wen Chuanen Zhou | 2020 | Journal of Integrative Plant Biology2020，62，12： | 4 |
| 19 | Chromosome-scale assembly of the Dendrobium chrysotoxum genome enhances the understanding of orchid evolution显示文摘As one of the largest families of angiosperms,the Orchidaceae family is diverse.Dendrobium represents the second largest genus of the Orchidaceae.However,an assembled high-quality genome of species in this genus is lacking.Here,we report a chromosome-scale reference genome of Dendrobium chrysotoxum,an important ornamental and medicinal orchid species.The assembled genome size of D.chrysotoxum was 1.37 Gb,with a contig N50 value of 1.54 Mb.Of the sequences,95.75%were anchored to 19 pseudochromosomes.There were 30,044 genes predicted in the D.chrysotoxum genome.Two whole-genome polyploidization events occurred in D.chrysotoxum.In terms of the second event,whole-genome duplication(WGD)was also found to have occurred in other Orchidaceae members,which diverged mainly via gene loss immediately after the WGD event occurred;the first duplication was found to have occurred in most monocots(tau event).We identified sugar transporter(SWEET)gene family expansion,which might be related to the abundant medicinal compounds and fleshy stems of D.chrysotoxum.MADS-box genes were identified in D.chrysotoxum,as well as members of TPS and Hsp90 gene families,which are associated with resistance,which may contribute to the adaptive evolution of orchids.We also investigated the interplay among carotenoid,ABA,and ethylene biosynthesis in D.chrysotoxum to elucidate the regulatory mechanisms of the short flowering period of orchids with yellow flowers.The reference D.chrysotoxum genome will provide important insights for further research on medicinal active ingredients and breeding and enhances the understanding of orchid evolution. | Yongxia Zhang Guo-Qiang Zhang Diyang Zhang Xue-Die Liu Xin-Yu Xu Wei-Hong Sun Xia Yu Xiaoen Zhu Zhi-Wen Wang Xiang Zhao Wen-Ying Zhong Hongfeng Chen Wei-Lun Yin Tengbo Huang Shan-Ce Niu Zhong-Jian Liu | 2021 | Horticulture Research2021，8，1： | 3 |
| 20 | A 10×10 deep ultraviolet light-emitting micro-LED array显示文摘In this work,we design and fabricate a deep ultraviolet(DUV)light-emitting array consisting of 10×10 micro-LEDs(μ-LEDs)with each device having 20μm in diameter.Strikingly,the array demonstrates a significant enhancement of total light output power by nearly 52%at the injection current of 100 mA,in comparison to a conventional large LED chip whose emitting area is the same as the array.A much higher(~22%)peak external quantum efficiency,as well as a smaller efficiency droop forμ-LED array,was also achieved.The numerical calculation reveals that the performance boost can be attributed to the higher light extraction efficiency at the edge of eachμ-LED.Additionally,the far-field pattern measurement shows that theμ-LED array possesses a better forward directionality of emission.These findings shed light on the enhancement of the DUV LEDs performance and provide new insights in controlling the light behavior of theμ-LEDs. | Huabin Yu Muhammad Hunain Memon Hongfeng Jia Haochen Zhang Meng Tian Shi Fang Danhao Wang Yang Kang Shudan Xiao Shibing Long Haiding Sun | 2022 | Journal of Semiconductors2022，43，6： | 3 |
