| 2 | Physics issues in diffraction limited storage ring design显示文摘Diffraction limited electron storage ring is considered a promising candidate for future light sources,whose main characteristics are higher brilliance,better transverse coherence and better stability.The challenge of diffraction limited storage ring design is how to achieve the ultra low beam emittance with acceptable nonlinear performance.Effective linear and nonlinear parameter optimization methods based on Artificial Intelligence were developed for the storage ring physical design.As an example of application,partial physical design of HALS(Hefei Advanced Light Source),which is a diffraction limited VUV and soft X-ray light source,was introduced.Severe emittance growth due to the Intra Beam Scattering effect,which is the main obstacle to achieve ultra low emittance,was estimated quantitatively and possible cures were discussed.It is inspiring that better performance of diffraction limited storage ring can be achieved in principle with careful parameter optimization. | FAN Wei BAI ZhengHe GAO WeiWei FENG GuangYao LI WeiMin WANG Lin HE DuoHui | 2012 | Science China(Physics,Mechanics & Astronomy)2012,55,5: | 2 |
| 3 | High performance organic transistors and phototransistors based on diketopyrrolopyrrole-quaterthiophene copolymer thin films fabricated via low-concentration solution processing显示文摘Conjugated polymers have received considerable attentions over the past years due to their large-area potential applications via low-cost solution processing.Improving crystallinity of conjugated polymer molecules in solution-processed thin films is crucial for their efficient charge transport and thus high performance optoelectronic devices.Herein,with diketopyrrolopyrrole-quaterthiophene(PDQT)copolymer as an example,it is found that by simply reducing the solution concentration for spincoating meanwhile with the assistance of post-annealing,significantly enhanced film crystallinity with formation of typical single crystalline domains is obtained,which benefits from the enough space for better molecular assembly especially at the semiconductor/dielectric interface.High performance polymer transistors and phototransistors were finally constructed based on the optimal lowconcentration(2 mg/mL)spin-coated PDQT films(12 nm),which giving a high charge carrier mobility of 2.28 cm^2V^(-1)s^(-1)and a photoresponse on/off ratio of 2.1×10~7at V_G=0 V under white light irradiation of6 mW/cm^2.The results suggest that the bright future of PDQT crystalline films for large-area flexible integrated optoelectronic devices and the application of effective low-concentration processing approach in solution-processed organic electronics with reduced material waste. | Pengcheng Gu Mengxiao Hu Shang Ding Guangyao Zhao Yifan Yao Feng Liu Xiaotao Zhang Huanli Dong Xiangke Wang Wenping Hu | 2018 | Chinese Chemical Letters2018,29,11: | 2 |
| 4 | N,P-codoped graphene supported few-layered MoS2 as a long-life and high-rate anode materials for potassium-ion storage显示文摘Layer-structured MoS_(2)is regarded as a promising anode material for potassium ion batteries.Herein,MoS_(2)nanosheets on N,P-codoping reduced graphene oxide(MoS_(2)/N,P-rGO)have been successfully prepared via a facile two-step synthesis,where few-layered MoS_(2)nanosheets are chemically bonded onto the surface of N,P-rGO.As an anode material,MoS_(2)/N,P-rGO exhibits a high specific capacity(462.7 mAh·g^(-1)at 100 mA·g^(-1)over 200 cycles),outstanding rate capability(224.9 mAh·g^(-1)at 20 A·g^(-1)),and excellent cycle life(236.6 mAh·g^(-1)at 2 A·g^(-1)after 7,000 cycles),much better than those of MoS_(2)and MoS_(2)/rGO.These advanced performances outperform most of the reported anode materials for potassium ion batteries to date.Meanwhile,the K-storage reactions of MoS_(2)/N,P-rGO have been disclosed through in-situ and ex-situ characterizations.The kinetics analysis confirms that K-storage of MoS_(2)/N,P-rGO is predominant by pseudo-capacitance. | Guangyao Ma Yanli Zhou Yingying Wang Zhenyu Feng Jian Yang | 2021 | Nano Research2021,14,10: | 2 |

| 9 | A stochastic reconstruction strategy based on a stratified library of structural descriptors and its application in the molecular reconstruction of naphtha显示文摘Molecular reconstruction is a rapid and reliable way to provide molecular detail of petroleum fractions,which is required in the kinetic modeling of petroleum conversation processes at the molecular level.In the typical stochastic reconstruction method,the estimation of properties of pseudo molecules that are generated by Monte Carlo sampling depends on the building of predefined molecular libraries,which is expensive and inaccessible for certain petroleum fractions.In this paper,a novel stochastic reconstruction strategy is proposed,which is based on a stratified library of structural descriptors.Properties of pseudo molecules generated in the novel strategy can be directly estimated by group contribution method in the condition of lacking predefined molecular libraries.In this strategy,the molecular building diagram comprises two steps.First,the ring structure is configured by determining the number of rings.Different from the length of chain adopted in the traditional stochastic reconstruction method,in the second step,number of structural descriptors(SDs)for binding site and chain were determined sequentially for the configuration of binding site and saturated acyclic hydrocarbon chain.These structural descriptors for binding site and chain were selected from group contribution methods.To count the number of partial overlapping sections between structural descriptors for chain,two supplementary structural descriptors were created.All possible saturated structures of hydrocarbon chains can be represented by structural descriptors at the scale of property estimation.This strategy separates the building of a predefined molecule library from the stochastic reconstruction process.The exact structures of pseudo molecules represented by structural descriptors in this work can be determined with sufficient chemical knowledge.Fifty naphtha samples are tested independently to demonstrate the performance of the proposed strategy and the results show that the estimated properties were close enough to the experimental values.This strategy will benefit the molecular management of petrochemical industries and therefore improve economic and environmental efficiencies. | Guangyao Zhao Minglei Yang Wenli Du Feifei Shen Feng Qian | 2022 | Chinese Journal of Chemical Engineering2022,,11: | 1 |

| 13 | 20世纪后期气候加速变暖促进了北半球树木径向生长显示文摘20世纪后期全球加速变暖导致北半球森林衰退事件频发,并增加了树木生长-气候关系的复杂性。然而,关于气候加速变暖前后北半球不同地区树木生长对气候因子响应的异质性研究仍较为缺乏。本研究利用北半球3大洲9个地区共计229条温度敏感型树轮宽度年表分析了气候加速变暖前后不同地区树木生长趋势和气候响应的异质性表现。结果表明:(i)1977–2000年期间,气候加速变暖显著促进了北半球不同地区树木的径向生长,但在1950–2000年期间,不同地区的树木径向生长表现出异质性特征。(ii)1976年后,除北美中部和欧洲北部,北半球树木生长和温度的相关性均显著增加,亚洲地区最为明显。(iii)在1977–2000年期间,9个地区的树木年轮指数与温度均出现了短暂的分离(2–5年)。在1950–2000年期间,各地区树木生长能够更好地追踪到北半球平均温度的变化趋势而不是区域温度。 | Jie Liu Zong-Shan Li Maierdang Keyimu Xiaochun Wang Haibin Liang Xiaoming Feng Guangyao Gao Bojie Fu | 2023 | Journal of Plant Ecology2023,16,1: | 0 |
| 14 | Macrocyclic versus acyclic preorganization in organoplatinum(Ⅱ)-based host-guest complexes显示文摘Two host-guest systems have been constructed,by employing structurally similar terpyridine platinum(II)macrocycle and molecular tweezer as the synthetic receptors.The macrocycle/guest complex displays low-energy emission signal,reinforced non-covalent binding affinity,and enhanced photosensitization capability than those of the molecular tweezer/guest one.The discrepancy between macrocyclic and acyclic preorganization modes originates from the different numbers of Pt(II)Pt(II)metal-metal bonds in host-guest complexation structures. | Xiaolong Zhang Yifei Han Guangyao Liu Feng Wang | 2019 | Chinese Chemical Letters2019,30,11: | 0 |
| 15 | Prognostic Significance of HbA1c Level in Asian Patients with Prediabetes and Coronary Artery Disease显示文摘Background:Measuring glycosylated hemoglobin(HbA1c)is a simple way to assess patients with prediabetes or diabetes mellitus.It has been shown that HbA1c level predicts prognosis in patients with coronary artery disease(CAD)and the incidence of diabetes mellitus.However,the prognostic significance of HbA1c level in Asian patients with prediabetes and CAD is not yet clear.Our study aimed to determine the relationship between HbA1c level and major adverse cardiovascular events(MACE)in patients with prediabetes and CAD.Methods:We enrolled 1367 patients with prediabetes and CAD in the final analysis,and grouped them according to the HbA1c level.Primary end points included nonfatal myocardial infarction,hospitalization for unstable angina,and ischemia-driven revascularization.Cox proportional-hazards regression analysis was used to determine the relation-ship between HbA1c level and MACE after our accounting for confounding factors.Results:A total of 1367 patients(age 58.8±10.3 years;71.6%men)were included.During 43 months of follow-up,197 patients experienced at least one primary end point event.Multivariate Cox proportional-hazards regression analy-sis showed in comparison of HbA1c levels that the hazard ratio for primary end points was 4.110,with a 95%confidence interval of 2.097-6.011(P<0.001).Conclusions:HbA1c level positively correlated with MACE,demonstrating it is a valuable indicator for indepen-dently predicting MACE in Asian patients with prediabetes and CAD. | Yang Liu Xunxun Feng Jiaqi Yang Tienan Sun Guangyao Zhai Qianyun Guo Yujie Zhou | 2022 | Cardiovascular Innovations and Applications2022,,1: | 0 |

| 17 | Genome resources for the elite bread wheat cultivar Aikang 58 and mining of elite homeologous haplotypes for accelerating wheat improvement显示文摘Despite recent progress in crop genomics studies,the genomic changes brought about by modern breeding selection are still poorly understood,thus hampering genomics-assisted breeding,especially in polyploid crops with compound genomes such as common wheat(Triticum aestivum).In this work,we constructed genome resources for the modern elite common wheat variety Aikang 58(AK58).Comparative genomics between AK58 and the landrace cultivar Chinese Spring(CS)shed light on genomic changes that occurred through recent varietal improvement.We also explored subgenome diploidization and divergence in common wheat and developed a homoeologous locus-based genome-wide association study(HGWAS)approach,which was more effective than single homoeolog-based GWAS in unraveling agronomic trait-associated loci.A total of 123 major HGWAs loci were detected using a genetic population derived from AK58 and cs.Elite homoeologous haplotypes(HHs),formed by combinations of subgenomic homoeologs of the associated loci,were found in both parents and progeny,and many could substantially improve wheat yield and related traits.We built a website where users can download genome assembly sequence and annotation data for AK58,perform blast analysis,and run JBrowse.Our work enriches genome resources for wheat,provides new insights into genomic changes during modern wheat improve-.ment,and suggests that efficientmining of elite HHs can make a substantial contribuutionto genomics-assisted breeding in common wheat and other polyploid crops. | Jizeng Jia Guangyao Zhao Danping Li Kai Wang Chuizheng Kong Pingchuan Deng Xueqing Yan Xueyong Zhang Zefu Lu Shujuan Xu Yuannian Jiao Kang Chong Xu Liu Dangqun Cui Guangwei Li Yijing Zhang Chunguang Du Liang Wu Tianbao Li Dong Yan Kehui Zhan Feng Chen Zhiyong Wang Lichao Zhang Xiuying Kong Zhengang Ru Daowen Wang Lifeng Gao | 2023 | Molecular Plant2023,16,12: | 0 |
