| 1 | Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype. | Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu | 2021 | Cell Research2021，31，3： | 9 |

| 3 | Confined van der Waals Epitaxial Growth of Two-Dimensional Large Single-Crystal In_(2)Se_(3) for Flexible Broadband Photodetectors显示文摘The controllable growth of two-dimensional(2D)semiconductors with large domain sizes and high quality is much needed in order to reduce the detrimental efect of grain boundaries on device performance but has proven to be challenging.Here,we analyze the precursor concentration on the substrate surface which signifcantly infuences nucleation density in a vapor deposition growth process and design a confned micro-reactor to grow 2D In_(2)Se_(3) with large domain sizes and high quality.Te uniqueness of this confned micro-reactor is that its size is∼102-103 times smaller than that of a conventional reactor.Such a remarkably small reactor causes a very low precursor concentration on the substrate surface,which reduces nucleation density and leads to the growth of 2D In_(2)Se_(3) grains with sizes larger than 200�m.Our experimental results show large domain sizes of the 2D In_(2)Se_(3) with high crystallinity.Te fexible broadband photodetectors based on the as-grown In_(2)Se_(3) show rise and decay times of 140 ms and 25 ms,efcient response(5.6 A/W),excellent detectivity(7×10^(10) Jones),high external quantum efciency(251%),good fexibility,and high stability.Tis study,in principle,provides an efective strategy for the controllable growth of high quality 2D materials with few grain boundaries. | Lei Tang Changjiu Teng Yuting Luo Usman Khan Haiyang Pan Zhengyang Cai Yue Zhao Bilu Liu Hui-Ming Cheng | 2019 | Research2019，，1： | 7 |

| 5 | Genome-and transcriptome-wide association studies provide insights into the genetic basis of natural variation of seed oil content in Brassica napus显示文摘Seed oil content(SOC)is a highly important and complex trait in oil crops.Here,we decipher the genetic basis of natural variation in SOC of Brassica napus by genome-and transcriptome-wide association studies using 505 inbred lines.We mapped reliable quantitative trait loci(QTLs)that control SOC in eight environments,evaluated the effect of each QTL on SOC,and analyzed selection in QTL regions during breeding.Six-hundred and ninety-two genes and four gene modules significantly associated with SOC were identified by analyzing population transcriptomes from seeds.A gene prioritization framework,POCKET(prioritizing the candidate genes by incorporating information on knowledge-based gene sets,effects of variants,genome-wide association studies,and transcriptome-wide association studies),was implemented to determine the causal genes in the QTL regions based on multi-omic datasets.A pair of homologous genes,BnPMT6s,in two QTLs were identified and experimentally demonstrated to negatively regulate SOC.This study provides rich genetic resources for improving SOC and valuable insights toward understanding the complex machinery that directs oil accumulation in the seeds of B.napus and other oil crops. | Shan Tang Hu Zhao Shaoping Lu Liangqian Yu Guofang Zhang Yuting Zhang Qing-Yong Yang Yongming Zhou Xuemin Wang Wei Ma Weibo Xie Liang Guo | 2021 | Molecular Plant2021，14，3： | 6 |

| 7 | Cold Stress-induced Glucosyltransferase CsUGT78A15 is Involved in the Formation of Eugenol Glucoside in Camellia sinensis显示文摘Eugenol is a natural phenolic compound known for its health-promoting properties and its ability to add a floral scent to tea plants.Plant eugenol glycosides have been identified and shown to make important contributions to fruit floral quality.However,the details of their biosynthesis and metabolism in tea plants are still unknown.Here,eugenol glucoside was unambiguously identified as a native metabolite in the tea plant,and its biosynthesis was shown to be induced by low temperature treatment.Through the analysis of UGTs induced by low temperature,the glycosyltransferase CsUGT78A15 was identified in tea,and its encoded protein was shown to catalyze the glucosylation of eugenol.Vmax/Km ratios showed that eugenol was the most suitable substrate for CsUGT78A15.Sugar donor preference analysis showed that CsUGT78A15 had a higher selectivity for glucose,followed by galactose and glucuronic acid.The expression of CsUGT78A15was correlatedwith the accumulation of eugenol glucoside in different tissues and genotypes of tea.Down-regulation of CsUGT78A15 led to a decreased eugenol glucoside content under cold stress,indicating that CsUGT78A15 plays an important role in the biosynthesis of eugenol glucoside under cold stress.The identification of eugenol glucoside in the tea plant and the discovery of a cold stress-induced eugenol glucosyltransferase in tea provide the foundation for the improvement of tea flavor under cold stress and the biotechnological production of eugenol glucoside. | Mingyue Zhao Binbin Cai Jieyang Jin Na Zhang Tingting Jing Jingming Wang Yuting Pan Zixiang Zhou Yifan Zhao Yingying Feng Feng Yu Mengting Zhang Yating Li Zhonghua Liu Chuankui Song | 2020 | Horticultural Plant Journal2020，6，6： | 4 |
| 8 | The integration of transcriptomic and transgenic analyses reveals the involvement of the SA response pathway in the defense of chrysanthemum against the necrotrophic fungus Alternaria sp.显示文摘Chrysanthemum morifolium cv.‘Huaihuang’has ornamental,edible,medicinal,and tea product uses.However,its field growth,yield,and quality are negatively affected by black spot disease caused by Alternaria sp.(Strain:HQJH10092301;GenBank accession number:KF688111).In this study,we transcriptionally and transgenically characterized a new cultivar,‘Huaiju 2#’(Henan Traditional Chinese Medicine Plant Cultivar identification number:2016002),which was bred from‘Huaihuang’and shows resistance to Alternaria sp.Numerous‘Huaiju 2#’plants were inoculated with Alternaria sp.for three or five days.Metabolic analysis showed increases in both salicylic acid(SA)and jasmonic acid(JA)in infected plants compared to the control.Protein activity analysis also revealed a significant increase in defense enzyme activities in infected plants.RNA-Seq of plants infected for 3 or 5 days produced a total of 58.6 GB of clean reads.Among these reads,16,550 and 13,559 differentially expressed genes(DEGs)were identified in Cm_3 dpi(sample from 3 days post-inoculation labeled as Cm_3 dpi)and Cm_5 dpi(sample from 5 days post-inoculation labeled as Cm_5 dpi),respectively,compared with their controls(Cm_0 d:a mixture samples from 0 d(before inoculation)and those treated with sterile distilled water at 3 dpi and 5 dpi).Gene annotation and cluster analysis of the DEGs revealed a variety of defense responses to Alternaria sp.infection,which were characterized by increases in resistance(R)proteins and the reactive oxygen species(ROS),Ca2+,mitogen-activated protein kinase(MAPK),and JA signaling pathways.In particular,SA signaling was highly responsive to Alternaria sp.infection.The qPCR analysis of 12 DEG candidates supported their differential expression characterized by using the RNA-Seq data.One candidate was CmNPR1(nonexpressor of pathogenesis-related gene 1),an important positive regulator of SA in systemic acquired resistance(SAR).Overexpression of CmNPR1 in‘Huaiju 2#’increased the resistance of transgenic plants to black spot.These findings indicate that the SA response pathway is likely involved in the defense of‘Huaiju 2#’against Alternaria sp.pathogens. | Xiting Zhao Lingyu Song Liwei Jiang Yuting Zhu Qinghui Gao Dandan Wang Jing Xie Meng Lv Ping Liu Mingjun Li | 2020 | Horticulture Research2020，7，1： | 3 |
| 9 | Flexible Operation Mode of Coal-fired Power Unit Coupling with Heat Storage of Extracted Reheat Steam显示文摘In order to provide more grid space for the renewable energy power,the traditional coal-fired power unit should be operated flexibility,especially achieved the deep peak shaving capacity.In this paper,a new scheme using the reheat steam extraction is proposed to further reduce the load far below 50%rated power.Two flexible operation modes of increasing power output mode and reducing fuel mode are proposed in heat discharging process.A 600 MW coal-fired power unit with 50%rated power is chosen as the research model.The results show that the power output is decreased from 300.03 MW to 210.07 MW when the extracted reheat steam flow rate is 270.70 t·h^(-1),which increases the deep peak shaving capacity by 15%rated power.The deep peak shaving time and the thermal efficiency are 7.63 h·d^(-1)and 36.91%respectively for the increasing power output mode,and they are 7.24 h·d^(-1)and 36.58%respectively for the reducing fuel mode.The increasing power output mode has the advantages of higher deep peak shaving time and the thermal efficiency,which is recommended as the preferred scheme for the flexible operation of the coal-fired power unit. | WEI Haijiao LU Yuanwei YANG Yanchun ZHANG Cancan WU Yuting LI Weidong ZHAO Dongming | 2022 | Journal of Thermal Science2022，31，2： | 3 |
| 10 | A male-ABCD algorithm for hepatocellular carcinoma risk prediction in HBs Ag carriers显示文摘Objective: Hepatocellular carcinoma(HCC) development among hepatitis B surface antigen(HBs Ag) carriers shows gender disparity, influenced by underlying liver diseases that display variations in laboratory tests. We aimed to construct a risk-stratified HCC prediction model for HBs Ag-positive male adults.Methods: HBs Ag-positive males of 35-69 years old(N=6,153) were included from a multi-center populationbased liver cancer screening study. Randomly, three centers were set as training, the other three centers as validation. Within 2 years since initiation, we administrated at least two rounds of HCC screening using Bultrasonography and α-fetoprotein(AFP). We used logistic regression models to determine potential risk factors,built and examined the operating characteristics of a point-based algorithm for HCC risk prediction.Results: With 2 years of follow-up, 302 HCC cases were diagnosed. A male-ABCD algorithm was constructed including participant's age, blood levels of GGT(γ-glutamyl-transpeptidase), counts of platelets, white cells,concentration of DCP(des-γ-carboxy-prothrombin) and AFP, with scores ranging from 0 to 18.3. The area under receiver operating characteristic was 0.91(0.90-0.93), larger than existing models. At 1.5 points of risk score,26.10% of the participants in training cohort and 14.94% in validation cohort were recognized at low risk, with sensitivity of identifying HCC remained 100%. At 2.5 points, 46.51% of the participants in training cohort and 33.68% in validation cohort were recognized at low risk with 99.06% and 97.78% of sensitivity, respectively. At 4.5 points, only 20.86% of participants in training cohort and 23.73% in validation cohort were recognized at high risk,with positive prediction value of 22.85% and 12.35%, respectively.Conclusions: Male-ABCD algorithm identified individual's risk for HCC occurrence within short term for their HCC precision surveillance. | Yuting Wang Minjie Wang He Li Kun Chen Hongmei Zeng Xinyu Bi Zheng Zhu Yuchen Jiao Yong Wang Jian Zhu Hui Zhao Xiang Liu Chunyun Dai Chunsun Fan Can Zhao Deyin Guo Hong Zhao Jianguo Zhou Dongmei Wang Zhiyuan Wu Xinming Zhao Wei Cui Xuehong Zhang Jianqiang Cai Wanqing Chen Chunfeng Qu | 2021 | Chinese Journal of Cancer Research2021，33，3： | 3 |
| 11 | Enhanced Heat Transfer of Carbon Nanotube Nanofluid Microchannels Applied on Cooling Gallium Arsenide Cell显示文摘Carbon nanotube nanofluids have wide application prospects due to their unique structure and excellent properties.In this study,the thermal conductivity properties of carbon nanotube nanofluids and SiO2/water nanofluids were compared and analyzed experimentally using different preparation methods.The physical properties of nanofluids were tested using a Malvern Zetasizer Nano Instrument and a Hot Disk Thermal Constant Analyzer.Combined with field synergy theory analysis of the heat transfer performance of nanofluids,results show that the thermal conductivity of carbon nanotube nanofluids is higher than that of SiO2/water nanofluids,and the thermal conductivity of nanofluid rises with the increase of mass fraction and temperature.Moreover,the synergistic performance of carbon nanotube nanofluids is also superior to that of SiO2/water nanofluids.When the mass fraction of the carbon nanotube nanofluids is 10%and the SiO2/water nanofluids is 8%,their field synergy numbers and heat transfer enhancement factors both reach maximum.From the perspective of the preparation method,the thermal conductivity of nanofluids dispersed by high shear microfluidizer is higher than that by ultrasonic dispersion.This result provides some reference for the selection and use of working substance in a microchannel cooling concentrated photovoltaic and thermal(CPV/T)system. | ZHANG Huiying YAN Suying WANG Tao WU Yuting ZHAO Xiaoyan ZHAO Ning | 2020 | Journal of Thermal Science2020，29，6： | 3 |
| 12 | Multi-scenario Simulation for 2060 and Driving Factors of the Eco-spatial Carbon Sink in the Beibu Gulf Urban Agglomeration, China显示文摘Since China announced its goal of becoming carbon-neutral by 2060, carbon neutrality has become a major target in the development of China's urban agglomerations. This study applied the Future Land Use Simulation(FLUS) model to predict the land use pattern of the ecological space of the Beibu Gulf urban agglomeration, in 2060 under ecological priority, agricultural priority and urbanized priority scenarios. The Integrated Valuation of Ecosystem Services and Trade-offs(In VEST) model was employed to analyse the spatial changes in ecological space carbon storage in each scenario from 2020 to 2060. Then, this study used a Geographically Weighted Regression(GWR) model to determine the main driving factors that influence the changes in land carbon sinking capacity. The results of the study can be summarised as follows: firstly, the agricultural and ecological priority scenarios will achieve balanced urban expansion and environmental protection of resources in an ecological space. The urbanized priority scenario will reduce the carbon sinking capacity. Among the simulation scenarios for 2060, carbon storage in the urbanized priority scenario will decrease by 112.26 × 10^(6) t compared with that for 2020 and the average carbon density will decrease by 0.96 kg/m^(2) compared with that for 2020. Carbon storage in the agricultural priority scenario will increase by 84.11 × 10^(6) t, and the average carbon density will decrease by 0.72 kg/m^(2). Carbon storage in the ecological priority scenario will increase by 3.03 × 10^(6) t, and the average carbon density will increase by 0.03 kg/m^(2). Under the premise that the population of the town will increases continuously, the ecological priority development approach may be a wise choice.Secondly, slope, distance to river and elevation are the most important factors that influence the carbon sink pattern of the ecological space in the Beibu Gulf urban agglomeration, followed by GDP, population density, slope direction and distance to traffic infrastructure.At the same time, urban space expansion is the main cause of the changes of this natural factors. Thirdly, the decreasing trend of ecological space is difficult to reverse, so reasonable land use policy to curb the spatial expansion of cities need to be made. | QIN Menglin ZHAO Yincheng LIU Yuting JIANG Hongbo LI Hang ZHU Ziming | 2023 | Chinese Geographical Science2023，33，1： | 3 |
| 13 | Modulating the optical and electrical properties of MAPbBr_(3) single crystals via voltage regulation engineering and application in memristors显示文摘Defect density is one of the most significant characteristics of perovskite single crystals(PSCs)that determines their optical and electrical properties,but few strategies are available to tune this property.Here,we demonstrate that voltage regulation is an efficient method to tune defect density,as well as the optical and electrical properties of PSCs.A three-step carrier transport model of MAPbBr_(3) PSCs is proposed to explore the defect regulation mechanism and carrier transport dynamics via an applied bias.Dynamic and steady-state photoluminescence measurements subsequently show that the surface defect density,average carrier lifetime,and photoluminescence intensity can be efficiently tuned by the applied bias.In particular,when the regulation voltage is 20 V(electrical poling intensity is 0.167 Vμm^(−1)),the surface defect density of MAPbBr_(3) PSCs is reduced by 24.27%,the carrier lifetime is prolonged by 32.04%,and the PL intensity is increased by 112.96%.Furthermore,a voltage-regulated MAPbBr_(3) PSC memristor device shows an adjustable multiresistance,weak ion migration effect and greatly enhanced device stability.Voltage regulation is a promising engineering technique for developing advanced perovskite optoelectronic devices. | Jun Xing Chen Zhao Yuting Zou Wenchi Kong Zhi Yu Yuwei Shan Qingfeng Dong Ding Zhou Weili Yu Chunlei Guo | 2020 | Light(Science & Applications)2020，9，1： | 3 |
| 14 | Highly-rough surface carbon nanofibers film as an effective interlayer for lithium–sulfur batteries显示文摘Lithium–sulfur(Li–S)battery with a new configuration is demonstrated by inserting a flexible nitrogen-doping carbon nanofiber(N-CNFs)interlayer between the sulfur cathode and the separator.The N-CNFs film with high surface roughness and surface area is fabricated by electrospinning and a subsequent calcination process.The N-CNFs film interlayer not only effectively traps the shuttling migration of polysulfides but also gives the whole battery reliable electronic conductivity,which can effectively enhance the electrochemical performance of Li–S batteries.Finally,Li–S batteries with long cycling stability of 785 mAh/g after 200 cycles and good rate capability of 573 mAh/g at 5 C are achieved. | Hongfan Zhu Mo Sha Huaping Zhao Yuting Nie Xuhui Sun Yong Lei | 2020 | Journal of Semiconductors2020，41，9： | 3 |
| 15 | FeCe nanocomposite with high iron content as efficient catalyst for generation of COx-free hydrogen via ammonia decomposition显示文摘FeCe nanocomposite catalysts with different iron contents were synthesized by a facile co-precipitation method.The as-prepared materials were characterized by various techniques including powder X-ray diffraction(XRD),N2 adsorption/desorption and high-resolution transmission electron microscopy(HRTEM).Catalyst with the highest iron content(90 FeCe) shows the best activity for the hydrogen generation via ammonia decomposition.83% NH3 conversion is achieved at 550℃ and nearly full conversion of NH3 is realized at 600℃ with a GHSV of 24000 cm3/(gcat·h).The large content and small size crystal particles of iron species are responsible for the good catalytic performance.Temperatureprogrammed reduction by hydrogen(H2-TPR) was performed to investigate the interaction between cerium and iron species.It is found that slight cerium can exert strong interaction with iron compound thus effectively prevent the self-aggregation of active iron species,so as to improve the catalytic activity for ammonia decomposition. | Yingqiu Gu Xiaoya Chen Shuang Zhao Yuting Zhang | 2020 | Journal of Rare Earths2020，38，10： | 3 |
| 16 | Chromosomal-level genome of macadamia(Macadamia integrifolia)显示文摘Macadamia from the family Proteaceae is a plant native to Australia and has long been favoured by people for its crispy and high nutritional and medicinal value.Here,the genome of GUIRE 1(GR1),a highly heterozygous superior cultivar of macadamia nut,was sequenced and assembled using nanopore sequencing,and a 807-Mb genome(contig N50,1.9 Mb;scaffold N50,54.70 Mb)and 14 chromosomes were obtained.A total of 453 Mb(about 55.95%)repetitive sequences and 37,657 protein-coding genes were obtained by gene annotation and homologous protein comparison.Proteaceae diverged from Nelumbonaceae nearly 115.37 million years ago and from Rubiaceae about 140 million years ago.A genome-wide duplication(WGD)event occurred in macadamia 41 million years ago based on the WGD analysis.The functional enrichment analysis of M.integrifolia-specific gene families revealed their roles in signal transduction,protein phosphorylation,protein binding,and defense response.Here,a highly heterozygous genome of M.integrifolia was unlocked to provide a database for breeding and molecular mechanism research. | Chengcai Xia Sirong Jiang Qiujin Tan Wenquan Wang Long Zhao Chenji Zhang Yuting Bao Qi Liu Jianjia Xiao Ke Deng Miaohua He Pengliang An Wenlin Wang Meiling Zou Zhiqiang Xia | 2022 | Tropical Plants2022，1，1： | 3 |
| 17 | Transient silencing mediated by in vitro synthesized double-stranded RNA indicates that PsCdc14 is required for sporangial development in a soybean root rot pathogen显示文摘In many eukaryotic organisms,Cdc14 phosphatase regulates multiple biological events during anaphase and is essential for mitosis.It has been shown that Cdc14 is required for sporulation in the potato blight pathogen Phytophthora infestans;however,the role that the Cdc14 homolog(PsCdc14) plays in the soil-borne soybean root rot pathogen P.sojae remains ambiguous.PsCdc14 is highly expressed in sporulation,zoospore,and cyst life stages,but not in vegetative mycelia and infection stages,suggesting that it contributes to asexual reproduction and thus the spread of the disease.Double-stranded RNA(dsRNA) mediates gene silencing,a post-transcriptional and highly conserved process in eukaryotes,involving specific gene silencing through degradation of target mRNA.We combined in vitro dsRNA synthesis and a polyethylene glycol-mediated transformation system to construct a dsRNA-mediated transient gene silencing system;and then performed a functional analysis of PsCdc14 in P.sojae.PsCdc14 mRNA was dramatically reduced in transformants after protoplasts were exposed in in vitro synthesized PsCdc14 dsRNA,resulting in low sporangial production and abnormal development in P.sojae silencing lines.Furthermore,dsRNA-mediated transient gene silencing could enable elucidation of P.sojae rapid gene function,facilitating our understanding of the development and pathogenicity mechanisms of this oomycete fungus. | ZHAO Wei YANG XinYu DONG SuoMeng SHENG YuTing WANG YuanChao ZHENG XiaoBo | 2011 | Science China(Life Sciences)2011，54，12： | 3 |
| 18 | A selected population study reveals the biochemical mechanism of intramuscular fat deposition in chicken meat显示文摘Background:Increasing intramuscular fat(IMF)is an important strategy to improve meat quality,but the regulation mechanism of IMF deposition needs to be systematically clarified.Results:A total of 520 chickens from a selected line with improved IMF content and a control line were used to investigate the biochemical mechanism of IMF deposition in chickens.The results showed that the increased IMF would improve the flavor and tenderness quality of chicken meat.IMF content was mainly determined both by measuring triglyceride(TG)and phospholipid(PLIP)in muscle tissue,but only TG content was found to be decisive for IMF deposition.Furthermore,the increase in major fatty acid(FA)components in IMF is mainly derived from TGs(including C16:0,C16:1,C18:1n9c,and C18:2n6c,etc.),and the inhibition of certain very-long-chain FAs would help to IMF/TG deposition.Conclusions:Our study elucidated the underlying biochemical mechanism of IMF deposition in chicken:Prevalent accumulation of long-chain FAs and inhibitions of medium-chain FAs and very long chain FA would jointly result in the increase of TGs with the FA biosynthesis and cellular uptake ways.Our findings will guide the production of high-quality chicken meat. | Huanxian Cui Lu Liu Xiaojing Liu Yongli Wang Na Luo Xiaodong Tan Yuting Zhu Ranran Liu Guiping Zhao Jie Wen | 2022 | Journal of Animal Science and Biotechnology2022，13，5： | 2 |
| 19 | Enhanced thermoelectric performance in Cl-doped BiSbSe_(3) with optimal carrier concentration and effective mass显示文摘Possessing inherently low thermal conductivity,BiSbSe_(3) is a promising thermoelectric material for medium temperature.Therefore,to substantially optimize the thermoelectric performance of BiSbSe_(3),researchers mainly focus on the strategies to improve its electrical transport properties.Among these strongly coupled thermoelectric parameters,carrier concentration and effective mass are two intrinsic variables to decisively affect the electrical transport properties.In this work,Cl as a donor dopant is effective to provide extra electrons in n-type BiSbSe_(3),and the carrier concentration and effective mass can be well optimized simultaneously with increasing Cl content owing to the multiple conduction bands in BiSbSe_(3).What’s more,maximum weighted mobility~53 cm^(2)V^(-1)s^(-1)is obtained in Cl-doped BiSbSe_(3),which contributes to a largely enhanced power factor~4.8μW cm^(-1)K^(-2)at room temperature and outperforms other halogen-doped BiSbSe_(3) samples.Finally,combining the significantly enhanced power factor and maintained low thermal conductivity,a maximum ZT~1.0 is achieved in Cl-doped BiSbSe_(3) at 800 K. | Sining Wang Lizhong Su Yuting Qiu Yu Xiao Li-Dong Zhao | 2021 | Journal of Materials Science & Technology2021，，11： | 2 |
| 20 | Exogenous SA or 6-BA maintains photosynthetic activity in maize leaves under high temperature stress显示文摘With global warming, high-temperature(HT) stress has become a major abiotic stress for crops, in particular summer maize in China. Photosynthesis is sensitive to HT. Salicylic acid(SA) and 6-benzyladenine(6-BA) can improve the adaptation of plants to various biotic and abiotic stresses. However, their contribution to maintaining photosynthetic activity and alleviating photoinhibition in maize leaves under HT stress is still unclear. The effects of exogenous SA or 6-BA on growth, photosynthesis capacity, photosystem Ⅱ(PSII) activity, subcellular ultrastructure, antioxidant system, and plant hormones in maize leaves under HT stress were investigated. Under HT conditions, application of SA or 6-BA up-regulated gibberellin and zeatin content in leaves, increasing leaf area index(LAI). It also expanded the stomata by reducing abscisic acid and jasmonic acid content in leaves, cooling them and increasing CO2supply to photosynthesis. A higher net photosynthetic rate, combined with increased activity of the antioxidant system, alleviated oxidative stress in maize plants sprayed with SA or 6-BA, allowing them to maintain their chloroplast ultrastructure and PSII activity, in particular electron transfer from QAto QB. The increased LAI and net photosynthetic rate per unit leaf area also resulted in the accumulation of more biomass. | Yuting Li Xuetao Han Hao Ren Bin Zhao Jiwang Zhang Baizhao Ren Huiyuan Gao Peng Liu | 2023 | The Crop Journal2023，11，2： | 2 |
