| 1 | Prussian Blue Analogues in Aqueous Batteries and Desalination Batteries显示文摘In the applications of large-scale energy storage,aqueous batteries are considered as rivals for organic batteries due to their environmentally friendly and low-cost nature.However,carrier ions always exhibit huge hydrated radius in aqueous electrolyte,which brings difficulty to find suitable host materials that can achieve highly reversible insertion and extraction of cations.Owing to open threedimensional rigid framework and facile synthesis,Prussian blue analogues(PBAs)receive the most extensive attention among various host candidates in aqueous system.Herein,a comprehensive review on recent progresses of PBAs in aqueous batteries is presented.Based on the application in different aqueous systems,the relationship between electrochemical behaviors(redox potential,capacity,cycling stability and rate performance)and structural characteristics(preparation method,structure type,particle size,morphology,crystallinity,defect,metal atom in highspin state and chemical composition)is analyzed and summarized thoroughly.It can be concluded that the required type of PBAs is different for various carrier ions.In particular,the desalination batteries worked with the same mechanism as aqueous batteries are also discussed in detail to introduce the application of PBAs in aqueous systems comprehensively.This report can help the readers to understand the relationship between physical/chemical characteristics and electrochemical properties for PBAs and find a way to fabricate high-performance PBAs in aqueous batteries and desalination batteries. | Chiwei Xu Zhengwei Yang Xikun Zhang Maoting Xia Huihui Yan Jing Li Haoxiang Yu Liyuan Zhang Jie Shu | 2021 | Nano-Micro Letters2021，13，11： | 4 |
| 2 | Cu3(PO4)2: Novel Anion Convertor for Aqueous Dual‑Ion Battery显示文摘Electrode materials which can reversibly react with anions are of interest for aqueous dual-ion batteries.Herein,we propose a novel anion electrode,Cu3(PO4)2,for constructing an aqueous dual-ion cell.The Cu3(PO4)2 electrode can operate in a quasi-neutral condition and deliver a reversible capacity of 115.6 mAh g^−1 with a well-defined plateau at−0.17 V versus Ag/AgCl.Its reaction mechanism shows that Cu3(PO4)2 decomposes into Cu2O and subsequently is converted into Cu during the initial discharge process.In the following charge process,Cu is oxidized into Cu2O.It suggests Cu3(PO4)2 reacts with OH−ions instead of PO43−ions after the initial discharge process and its potential thereby depends upon the OH−ions concentration in electrolyte.Additionally,an aqueous dual-ion cell is built by using pretreated Cu3(PO4)2 and Na0.44MnO2 as anode and cathode,respectively.During cycling,OH−ions and Na^+ions in electrolyte can be stored and released.Such a cell can provide a discharge capacity of 52.6 mAh g^−1 with plateaus at 0.70 and 0.45 V,exhibiting the potential of application.This work presents an available aqueous dual-ion cell and provides new insights into renewable energy storage and adjustment of the OH−ions concentration in aqueous buffer solution. | Haoxiang Yu Chenchen Deng Huihui Yan Maoting Xia Xikun Zhang Zhen‑Bo Wang Jie Shu | 2021 | Nano-Micro Letters2021，13，3： | 3 |
| 3 | Hydrogen Bond-Assisted Ultra-Stable and Fast Aqueous NH_(4)^(+)Storage显示文摘Aqueous ammonium ion batteries are regarded as eco-friendly and sustainable energy storage systems.And applicable host for NH_(4)^(+)in aqueous solution is always in the process of development.On the basis of density functional theory calcula-tions,the excellent performance of NH_(4)^(+)insertion in Prussian blue analogues(PBAs)is proposed,especially for copper hexacyanoferrate(CuHCF).In this work,we prove the outstanding cycling and rate performance of CuHCF via electrochemical analyses,delivering no capacity fading during ultra-long cycles of 3000 times and high capacity retention of 93.6%at 50 C.One of main contributions to superior performance from highly reversible redox reaction and structural change is verified during the ammoniation/de-ammoniation progresses.More importantly,we propose the NH_(4)^(+)diffusion mechanism in CuHCF based on con-tinuous formation and fracture of hydrogen bonds from a joint theoretical and experimental study,which is another essential reason for rapid charge transfer and superior NH_(4)^(+)storage.Lastly,a full cell by coupling CuHCF cathode and polyaniline anode is constructed to explore the practical application of CuHCF.In brief,the outstanding aqueous NH_(4)^(+)storage in cubic PBAs creates a blueprint for fast and sustainable energy storage. | Xikun Zhang Maoting Xia Haoxiang Yu Junwei Zhang Zhengwei Yang Liyuan Zhang Jie Shu | 2021 | Nano-Micro Letters2021，13，9： | 2 |
| 4 | Evaluation of the China Ocean Reanalysis (CORA) in the South China Sea显示文摘The daily regional reanalysis product of the China Ocean Reanalysis(CORA)product was released in website in 2018.Using in situ observational data including Argo profiling floats,drifters,and cruise data,the performance of CORA in the South China Sea in terms of temperature,salinity,current and mixed layer depths is evaluated based on timescale(seasonal and interannual)and spatial distribution characteristics.The CORA temperature,salinity,and mixed layer depth show certain seasonal and interannual variations.In 50-400 m depth in the SCS,the CORA temperature is colder in winter and warmer in summer and autumn.In 0-150 m in the SCS,the CORA salinity is higher in most time of the year.However,in the second half of the year,the salinity is slightly weaker in 100-150 m depth.In most years,the CORA mixed layer depths tend to be shallower,and in season,shallower in winter and deeper in summer.In spatial distribution,the closer the area is to the coast,the greater the CORA errors would be.The CORA temperature is colder in the western side and warmer in the eastern side,resulting in a weaker SCS western boundary current(SCSwbc).In most areas,the CORA mixed layer depths are shallower.In the area close to the coast,the CORA mixed layer depths change rapidly,and the deviations in the mixed layer depths are larger.In the central SCS,the CORA mixed layer depths change slowly,and the deviations in the mixed layer depths are also small. | FAN Maoting WANG Huizan ZHANG Weimin HAN Guijun WANG Pinqiang | 2020 | Journal of Oceanology and Limnology2020，38，6： | 2 |
| 5 | Groundwater Nitrate Contamination and Driving Forces from Intensive Cropland in the North China Plain显示文摘High nitrate in groundwater is a serious problem especially in highly active agricultural areas.In this paper,the concentration and spatial distribution of groundwater nitrate in cropland area in the North China Plain were assessed by statistical and geostatistical techniques.Nitrate concentration in groundwater reached a maximum of 526.58 mg/L,and 47.2%,21.33%and 11.13%of samples had levels in excess of nitrate safety threshold concentration(50 mg/L)in shallow,middle-deep and deep groundwater,respectively.And NO-3 content significantly decreased with groundwater depth.Groundwater nitrate concentrations under vegetable area are significantly higher than ones under grain and orchard.And there are great differences in spatial distribution of nitrate in the North China Plain and pollution hotspot areas are mainly in Shandong Province.Based on both multiple regressions combined with principal component analysis(PCA),significant variables for nitrate variation in three types of ground water were found:population per unit area,percentage of vegetable area,percentage of grain crop area,livestock per unit area,annual precipitation and annual mean temperature for shallow groundwater;population per unit area and percentage of vegetable area for middle-deep groundwater;percentage of vegetable area,percentage of grain crop area and livestock per unit area for deep groundwater. | Jing LIU Chengjun ZHANG Peng LI Shunjiang LI Maoting MA Guoyin ZHANG Xianbiao GAO Changlin KOU Lihua JIANG Tongke ZHAO | 2019 | Asian Agricultural Research2019，11，9： | 1 |

| 7 | Central nervous system injury meets nanoceria:opportunities and challenges显示文摘Central nervous system(CNS)injury,induced by ischemic/hemorrhagic or traumatic damage,is one of the most common causes of death and long-term disability worldwide.Reactive oxygen and nitrogen species(RONS)resulting in oxidative/nitrosative stress play a critical role in the pathological cascade of molecular events after CNS injury.Therefore,by targeting RONS,antioxidant therapies have been intensively explored in previous studies.However,traditional antioxidants have achieved limited success thus far,and the development of new antioxidants to achieve highly effective RONS modulation in CNS injury still remains a great challenge.With the rapid development of nanotechnology,novel nanomaterials provided promising opportunities to address this challenge.Within these,nanoceria has gained much attention due to its regenerative and excellent RONS elimination capability.To promote its practical application,it is important to know what has been done and what has yet to be done.This review aims to present the opportunities and challenges of nanoceria in treating CNS injury.The physicochemical properties of nanoceria and its interaction with RONS are described.The applications of nanoceria for stroke and neurotrauma treatment are summarized.The possible directions for future application of nanoceria in CNS injury treatment are proposed. | Wang Yang Maoting Zhang Jian He Mingfu Gong Jian Sun Xiaochao Yang | 2022 | Regenerative Biomaterials2022，9，1： | 0 |
