| 1 | Spatial Pattern and Benefit Allocation in Regional Collaborative Innovation of the Yangtze River Delta, China显示文摘As an important step enhancing regional innovation, researches on collaborative innovation have attracted much more attention recently. One significant reason is that cities can get excessive benefits while they take collaborative innovation activities. Based on the theories of innovation geography, this paper takes the collaborative innovation of the Yangtze River Delta(YRD) Urban Agglomeration as a case study and measures the collaborative innovation capacity from innovation actors and innovation cities by adopting the catastrophe progression model. Then on this basis, the study depicts the spatial pattern and the benefit allocation of collaborative innovation by using the coupling collaborative degree model and benefit allocation model of collaborative innovation. The results show that:1) The collaborative innovation capacity of cities in the Yangtze River Delta has strengthened largely, while the capacity still is not high enough. Cities with high collaborative innovation capacity are concentrated in Shanghai, the southern part of Jiangsu, and Hangzhou Bay, yet the cooperation of the universities-industries-research institutes need to improve. 2) The spatial pattern of collaborative innovation of the Yangtze River Delta presents several innovation circles, which are in Suzhou-Wuxi-Changzhou Metropolitan Circle, Nanjing Metropolitan Circle, Hangzhou Metropolitan Circle, Ningbo Metropolitan Circle, and Hefei Metropolitan Circle. Shanghai plays the role of the central city of collaborative innovation, while Suzhou, Nanjing, Hangzhou, Ningbo, and Hefei act as sub-central cities. 3) The benefit each city allocated from collaborative innovation activities has increased. However, the allocations of the benefit show that cities with higher innovation capacity have significant advantages in most cases, which lead to serious disparities in space. | WANG Yue WANG Chengyun MAO Xiyan Liu Binglin ZHANG Zhenke JIANG Shengnan | 2021 | Chinese Geographical Science2021，31，5： | 1 |
| 2 | An organosulfide-based energetic liquid as the catholyte in highenergy density lithium metal batteries for large-scale grid energy storage显示文摘Development of catholytes with long-cycle lifespan,high interfacial stability,and fast electrochemical kinetics is crucial for the comprehensive deployment of high-energy density lithium metal batteries(LMBs)with cost-efficiency.In this study,a lithiated 2-mercaptopyridine(2-MP-Li)organosulfide was synthesized and used as the soluble catholyte for the first time.Under the routine working mode,the LMB using this 2-MP-Li catholyte possessed high capacity retention of 55.4%with a Coulombic efficiency(CE)of near 100%after 2,000 cycles.When a cell system was fully filled with 2-MP-Li catholyte,it yielded a double capacity with 15%improvement in the capacity retention,corresponding to 0.0182%capacity decay per cycle,as well as excellent rate performance even at 6 mA·cm^(−2).These superior achievements resulted from the enhanced interfacial stability of Li anode induced by the salt-type 2-MP-Li molecule and the avoiding of using neutral catholyte as the initial active material,thereby mitigating the side reactions originating from the polysulfide shuttle effect.Furthermore,density functional theory(DFT)calculation and kinetics investigations proved the pseudocapacitive characteristic and faster ion diffusion coefficient with this design.Besides,the fabricated energy storage device showed excellent performance but with low economic cost and easy processing.Such a LMB with an alterable amount of capacity has a high potential to be applied in flow-cell type batteries for large-scale grid energy storage in the future. | Zhengkun Xie Zeying Yang Xiaowei An Xiyan Yue Jiajia Wang Shusheng Zhang Weihua Chen Abuliti Abudula Guoqing Guan | 2022 | Nano Research2022，15，7： | 0 |
| 3 | ERF5.1 modulates carotenoid accumulation by interacting with CCD4.1 in Lycium显示文摘Carotenoids are important natural pigments and have medical and health functions for humans.Carotenoid cleavage dioxygenase 4(CCD4)and ethylene responsive factor(ERF)participate in carotenoid metabolism,but their roles in Lycium have not been discovered.Here,we annotated LbCCDs from the Lycium reference genome and found that LbCCD4.1 expression was significantly correlated with the carotenoid metabolites during Lycium five fruit developmental stages.Over-expression of LbCCD4.1 in NQ’s leaves resulted in a series of significantly lower contents of carotenoid metabolites,includingβ-carotene andβ-cryptoxanthin.Moreover,LbERF5.1,a transcription factor belonging to the ERF family that was located in the nucleus,was isolated.Significant reductions in the carotenoids,especially lutein,violaxanthin and their derivatives,were observed in over-expressing ERF5.1 transgenic NQ’s leaves.Over-expression or virus-induced gene silencing of LbERF5.1 in NQ’s leaves induced a consistent up-or down-expression,respectively,of LbCCD4.1.Furthermore,yeast one-hybrid and dual-luciferase reporter assays showed that ERF5.1 interacted with the promoter of CCD4.1 to increase its expression,and LbERF5.1 could bind to any one of the three predicted binding sites in the promoter of LbCCD4.1.A transcriptome analysis of LbERF5.1 and LbCCD4.1 over-expressed lines showed similar global transcript expression,and geranylgeranyl diphosphate synthase,phytoene synthase,lycopeneδ-cyclase cytochrome,cytochrome P450-type monooxygenase 97A,cytochrome P450-type monooxygenase 97C,and zeaxanthin epoxidase in the carotenoid biosynthesis pathway were differentially expressed.In summary,we uncovered a novel molecular mechanism of carotenoid accumulation that involved an interaction between ERF5.1 and CCD4.1,which may be used to enhance carotenoid in Lycium. | Jianhua Zhao Yuhui Xu Haoxia Li Xinlei Zhu Yue Yin Xiyan Zhang Xiaoya Qin Jun Zhou Linyuan Duan Xiaojie Liang Ting Huang Bo Zhang Ru Wan Zhigang Shi Youlong Cao Wei An | 2023 | Horticulture Research2023，10，12： | 0 |

| 5 | Fluoropyridine family:Bifunction as electrolyte solvent and additive to achieve dendrites-free lithium metal batteries显示文摘Electrolyte formulation with high stability towards both Li metal anode and high-voltage cathode is considered as one of key points for the high-energy density lithium metal batteries(LMBs).In our previous study,by adding only 2%of 2-fluoropyridine(2-FP)as the additive in the carbonate and ether-based electrolyte formulations effectively suppressed Li dendrite growth.In this study,we further found that the main fluoropyridine(FP)family members can serve as not only the effective additive but also the excellent electrolyte solvent in the electrolyte formulations to enhance the performance of LMBs.For the 2-FP,when it was also used the electrolyte solvent and paired with single-salt lithium bis(trifluoromethylsulfonyl)imide(Li TFSI),the obtained electrolyte formulation of 1 M Li TFSI in pure2-FP solvent not only allowed faster ion transport though solvation effect,but also possessed impressive oxidation stability window over 4.3 V.As a result,the high-voltage LiNi_(1/3)Mn1_(/3)Co_(1/3)O_(2)(1.5 mA h cm^(-2))|Li metal battery with it exhibited a capacity retention of more than 80%over a long-term cycle even at 0.45 m A cm^(-2)with a lean electrolyte(30μL).Meanwhile,for another FP family member(i.e.,3-FP)as the electrolyte additive,the 4.3 V LMBs with the carbonate-based electrolyte containing only 1%of 3-FP maintained 83.9%of initial capacity after 200 cycles at 0.75 m A cm^(-2).Density functional theory(DFT)calculations and experiments confirmed that three typical FPs,i.e.,2-FP,3-FP and 4-FP can not only regulate the initial Li nucleation process,but more importantly also induce a protective layer,leading to a uniform and dendrites-free Li deposition.This bifunction of the FP family member as either electrolyte solvent or additive in the electrolyte formulations should be promising for the achieving of dendrites-free high-energy density LMBs. | Zhengkun Xie Xiaowei An Zhijun Wu Xiyan Yue Jiajia Wang Xiaogang Hao Abuliti Abudula Guoqing Guan | 2021 | Journal of Materials Science & Technology2021，，15： | 0 |
