| 2 | Ultra-thin CoAl layered double hydroxide nanosheets for the construction of highly sensitive and selective QCM humidity sensor显示文摘To achieve real-time monitoring of humidity in various applications,we prepared facile and ultra-thin CoAl layered double hydroxide(CoAl LDH)nanosheets to engineer quartz crystal microbalances(QCM).The characteristics of CoAl LDH were investigated by transmission electron microscopy(TEM),X-ray diffraction(XRD),X-ray photoelectric spectroscopy(XPS),Brunauer–Emmett–Telle(BET),atomic force microscopy(AFM)and zeta potential.Due to their large specific surface area and abundant hydroxyl groups,CoAl LDH nanosheets exhibit good humidity sensing performance.In a range of 11.3%and 97.6%relative humidity(RH),the sensor behaved an ultrahigh sensitivity(127.8 Hz/%RH),fast response(9.1 s)and recovery time(3.1 s),low hysteresis(3.1%RH),good linearity(R^(2)=0.9993),stability and selectivity.Besides,the sensor can recover the initial response frequency after being wetted by deionized water,revealing superior self-recovery ability under high humidity.Based on in-situ Fourier transform infrared spectroscopy(FT-IR),the adsorption mechanism of CoAl LDH toward water molecules was explored.The QCM sensor can distinguish different respiratory states of people and wetting degree of fingers,as well as monitor the humidity in vegetable packaging,suggesting excellent properties and a promising application in humidity sensing. | Yongheng Zhu Xuhua Dong Jinsheng Cheng Lumin Wang Cheng Zhao Yonghui Deng Siqi Xie Yingjie Pan Yong Zhao Gengzhi Sun Tianjun Ni | 2023 | Chinese Chemical Letters2023，34，8： | 1 |

| 6 | Recent Changes of Northern Indian Ocean Summer Rainfall Based on CMIP5 Multi-Model显示文摘This study evaluates the simulation of summer rainfall changes in the Northern Indian Ocean (NIO) based on the fifth phase of Coupled Model Intercomparison Project (CMIP5). The historical runs of 20 CMIP5 coupled General Circulation Models (GCMs) are analyzed. The Multi-Model ensemble (MME) of the CMIP5 models well reproduces the general feature of NIO summer rainfall. For a short period 1979?2005, 14 out of 20 models show an increased trend in the mean rainfall and a similar spatial distri-bution to the Global Precipitation Climatology Project (GPCP) observations in MME. The increasing of the convergence in the equatorial IO results in the increase of rainfall significantly. The equatorial rainfall trend patterns seem modulated by the SST warm-ing in the tropical Indian Ocean, which confirm the mechanism of 'warmer-get-wetter' theory. For a long period 1950?2005, the trend of monsoon rainfall over India shows a decrease over the most parts of the India except an increase over the south corn er of the Indian Peninsula, due to a weakened summer monsoon circulation. The pattern is well simulated in half of the CMIP5 models. The rainfall over the north India is different for a short period, in which rainfall increases in 1979?2005, implying possible decadal varia-tion in the NIO summer climate. | YANG Yali DU Yan ZHANG Yuhong CHENG Xuhua | 2013 | Journal of Ocean University of China2013，12，2： | 1 |

| 9 | Interannual variability in the barrier layer and forcing mechanism in the eastern equatorial Indian Ocean and Bay of Bengal显示文摘Interannual variability(IAV)in the barrier layer thickness(BLT)and forcing mechanisms in the eastern equatorial Indian Ocean(EEIO)and Bay of Bengal(BoB)are examined using monthly Argo data sets during 2002–2017.The BLT during November–January(NDJ)in the EEIO shows strong IAV,which is associated with the Indian Ocean dipole mode(IOD),with the IOD leading the BLT by two months.During the negative IOD phase,the westerly wind anomalies driving the downwelling Kelvin waves increase the isothermal layer depth(ILD).Moreover,the variability in the mixed layer depth(MLD)is complex.Affected by the Wyrtki jet,the MLD presents negative anomalies west of 85°E and strong positive anomalies between 85°E and 93°E.Therefore,the BLT shows positive anomalies except between 86°E and 92°E in the EEIO.Additionally,the IAV in the BLT during December–February(DJF)in the BoB is also investigated.In the eastern and northeastern BoB,the IAV in the BLT is remotely forced by equatorial zonal wind stress anomalies associated with the El Ni?o-Southern Oscillation(ENSO).In the western BoB,the regional surface wind forcing-related ENSO modulates the BLT variations. | Tian Ma Xuhua Cheng Yiquan Qi Jiajia Chen | 2020 | Acta Oceanologica Sinica2020，39，7： | 0 |
| 10 | Interannual variability of the spring Wyrtki Jet显示文摘Features of the interannual variability of the spring Wyrtki Jet in the tropical Indian Ocean are revealed using observation data and model output.The results show that the jet has signifi cant interannual variation,which has a signifi cant correlation with winter El Niño Modoki index(R=0.62).During spring after an El Niño(La Niña)Modoki event,the Wyrtki Jet has a positive(negative)anomaly,forced by a westerly(easterly)wind anomaly.The result of a linear-continuously stratifi ed model shows that the fi rst two baroclinic modes explain most of the interannual variability of the spring Wyrtki Jet(~70%)and the third to fi fth modes together account for approximately 30%.Surface wind anomalies in the tropical Indian Ocean are related to the Walker circulation anomaly associated with El Niño/La Niña Modoki.The interannual variability of the spring Wyrtki Jet has an evident impact on sea surface salinity transport before the onset phase of the summer monsoon in the Indian Ocean. | Kangping DENG Xuhua CHENG Tao FENG Tian MA Wei DUAN Jiajia CHEN | 2021 | Journal of Oceanology and Limnology2021，39，1： | 0 |
| 11 | A conductive supramolecular hydrogel creates ideal endogenous niches to promote spinal cord injury repair显示文摘The current effective method for treatment of spinal cord injury(SCI)is to reconstruct the biological microenvironment by filling the injured cavity area and increasing neuronal differentiation of neural stem cells(NSCs)to repair SCI.However,the method is characterized by several challenges including irregular wounds,and mechanical and electrical mismatch of the material-tissue interface.In the current study,a unique and facile agarose/gelatin/polypyrrole(Aga/Gel/PPy,AGP3)hydrogel with similar conductivity and modulus as the spinal cord was developed by altering the concentration of Aga and PPy.The gelation occurred through non-covalent interactions,and the physically crosslinked features made the AGP3 hydrogels injectable.In vitro cultures showed that AGP3 hydrogel exhibited excellent biocompatibility,and promoted differentiation of NSCs toward neurons whereas it inhibited over-proliferation of astrocytes.The in vivo implanted AGP3 hydrogel completely covered the tissue defects and reduced injured cavity areas.In vivo studies further showed that the AGP3 hydrogel provided a biocompatible microenvironment for promoting endogenous neurogenesis rather than glial fibrosis formation,resulting in significant functional recovery.RNA sequencing analysis further indicated that AGP3 hydrogel significantly modulated expression of neurogenesis-related genes through intracellular Ca2+signaling cascades.Overall,this supramolecular strategy produces AGP3 hydrogel that can be used as favorable biomaterials for SCI repair by filling the cavity and imitating the physiological properties of the spinal cord. | Biao Yang Chengzhen Liang Di Chen Feng Cheng Yuang Zhang Shaoke Wang Jiawei Shu Xianpeng Huang Jingkai Wang Kaishun Xia Liwei Ying Kesi Shi Chenggui Wang Xuhua Wang Fangcai Li Qian Zhao Qixin Chen | 2022 | Bioactive Materials2022，7，9： | 0 |
| 12 | Eddy generation mechanism in the eastern South China Sea显示文摘Mesoscale eddy generation mechanisms in the eastern South China Sea(ESCS) are investigated using altimetry observations and solutions of a nonlinear, 1?-layer reduced-gravity model. We estimate the relative roles of the wind forcing in the interior South China Sea(SCS) and the remote forcing from the western tropical Pacific(WTP)in eddy generation in the ESCS. Model solutions show that the high-frequency wind in the interior SCS is the primary forcing for eddies, which explains about 54% of the mesoscale eddies generated in the ESCS. Signals from the WTP also play an important role. Wind-driven equatorial signals reach the west coast of Luzon Island through the Sibutu Passage and Mindoro Strait. The reflected Rossby waves from the west coast of Luzon Island propagate westward, become unstable, and turn into eddies. The signals driven by high-frequency wind from the WTP explain about 40% of the mesoscale eddies generated in the ESCS. The high-frequency wind forcing in both the SCS and the WTP is important for eddy generation in the ESCS. | Jiajia Chen Xuhua Cheng Xiao Chen | 2019 | Acta Oceanologica Sinica2019，38，4： | 0 |
| 13 | Study on the interannual variability of the Kerama Gap transport and its relation to the Kuroshio/Ryukyu Current system显示文摘An analysis of a 68-year monthly hindcast output from an eddy-resolving ocean general circulation model reveals the relationship between the interannual variability of the Kerama Gap transport(KGT)and the Kuroshio/Ryukyu Current system.The study found a significant difference in the interannual variability of the upstream and downstream transports of the East China Sea-(ECS-)Kuroshio and the Ryukyu Current.The interannual variability of the KGT was found to be of paramount importance in causing the differences between the upstream and downstream ECS-Kuroshio.Additionally,it contributed approximately 37%to the variability of the Ryukyu Current.The interannual variability of the KGT was well described by a two-layer rotating hydraulic theory.It was dominated by its subsurface-intensified flow core,and the upper layer transport made a weaker negative contribution to the total KGT.The subsurface flow core was found to be mainly driven by the subsurface pressure head across the Kerama Gap,and the pressure head was further dominated by the subsurface density anomalies on the Pacific side.These density anomalies could be traced back to the eastern open ocean,and their propagation speed was estimated to be about 7.4 km/d,which is consistent with the speed of the local first-order baroclinic Rossby wave.When the negative(positive)density anomaly signal reached the southern region of the Kerama Gap,it triggered the increase(decrease)of the KGT towards the Pacific side and the formation of an anticyclonic(cyclonic)vortex by baroclinic adjustment.Meanwhile,there is an increase(decrease)in the upstream transport of the entire Kuroshio/Ryukyu Current system and an offshore flow that decreases(increases)the downstream Ryukyu Current. | Han Zhou Kai Yu Jianhuang Qin Xuhua Cheng Meixiang Chen Changming Dong | 2024 | Acta Oceanologica Sinica2024，43，3： | 0 |
| 14 | Dynamics of seasonal and interannual variability of the ocean bottom pressure in the Southern Ocean显示文摘Seasonal and interannual variability of ocean bottom pressure(OBP)in the Southern Ocean was investigated using Gravity Recovery and Climate Experiment(GRACE)data and a Pressure Coordinate Ocean Model(PCOM)based on mass conservation.By comparing OBP,steric sea level,and sea level,it is found that at high latitudes the OBP variability dominates the sea level variability at seasonal-to-decadal time scales.The diagnostic OBP based on barotropic vorticity equation has a good correlation with the observations,indicating that wind forcing plays an important role in the variability of the OBP in the Southern Ocean.The unique interannual patterns of OBP in the Southern Ocean are closely associated with El Niño-Southern Oscillation(ENSO)and Southern Annular Mode(SAM).Regression analysis indicates that ENSO and SAM influence the OBP through altering the Ekman transport driven by surface wind.The leading pattern of OBP from PCOM are very similar to observations.Sensitive experiments of PCOM show that surface wind forcing explains the observed OBP variability quite well,confirming the importance of wind forcing and related oceanic processes.In the eastern South Pacific,the averaged OBP shows a decrease(increase)trend before(after)2011,reflecting the reverse trend in westerly wind.In the South Indo-Atlantic Ocean,the averaged OBP has a weak increase trend during 2003–2016. | Xiaoqin Xiong Xuhua Cheng Niansen Ou Tao Feng Jianhuang Qin Xiao Chen Rui Xin Huang | 2022 | Acta Oceanologica Sinica2022，41，5： | 0 |
| 15 | Rational design and synthesis of upconversion luminescence-based optomagnetic multifunctional nanorattles for drug delivery显示文摘Optomagnetic multifunctional composite based on upconversion luminescence nanomaterial is regarded as a promising strategy for bioimaging,disease diagnosis and targeted delivery of drugs.To explore a mesoporous nanostructure with excellent water dispersibility and high drug-loading capacity,a novel nanorattle-structured Fe3O4@SiO2@NaYF4:Yb,Er magnetic upconversion nanorattle(MUCNR)was successfully designed by using Fe3O4 as core and NaYF4:Yb,Er nanocrystals as shell.The microstructures and crystal phase of the as-prepared MUCNRs were evaluated by transmission electron microscopy,Xray powder diffraction and N2 adsorption/desorption isotherms.The Kirkendall effect was adapted to explain the formation mechanism of the MUCNRs.The loading content and encapsulation efficiency of doxorubicin hydrochloride(DOX)could reach as high as 18.2%and 60.7%,respectively.Moreover,the DOX loading MUCNR(DOX-MUCNR)system showed excellent sustained drug release and strong p Hdependent performance,which was conducive to drug release at the slightly acidic microenvironment of tumor.Microcalorimetry was used to quantify the interactions between the carrier structure and drug release rate directly.The heat release rates in the heat-flow diagrams are basically consistent with the DOX release rate,thereby showing that microcalorimetry assay not only provides a unique thermodynamic explanation for the structure–activity relationship of Fe3O4@SiO2@NaYF4:Yb,Er MUCNRs but also provides powerful guidance to avoid the blind selection or design of drug carriers.Therefore,our work firmly provided a comprehensive perspective for using Fe3O4@SiO2@NaYF4:Yb,Er MUCNRs as a remarkable magnetic targeted drug carrier. | Xuhua Liang Yanyan Zhao Min Cheng Fei Zhang | 2021 | Chinese Journal of Chemical Engineering2021，34，10： | 0 |
| 16 | Submesoscale motions and their seasonality in the northern Bay of Bengal显示文摘The unbalanced submesoscale motions and their seasonality in the northern Bay of Bengal(BoB)are investigated using outputs of the high resolution regional oceanic modeling system.Submesoscale motions in the forms of filaments and eddies are present in the upper mixed layer during the whole annual cycle.Submesoscale motions show an obvious seasonality,in which they are active during the winter and spring but weak during the summer and fall.Their seasonality is associated with the mixed layer instability that depends on the mixed layer depth(MLD).During the winter,the MLD provides a much greater reservoir of the available potential energy,which promotes mixed layer instability to develop active submesoscale motions.The variations of MLD are likely modulated by the larger scale motions and the influxes of freshwater.Further investigations imply that the MLD and the stratified barrier layer are combined to determine the vertical structure of the submesoscale motions.The shallow MLD and strong stratification below during the summer and fall seem to prevent the downward extension of submesoscale motions.But in spring when the weak stratification exists,the penetration depth exceeds the base of the barrier layer. | Lanman Li Xuhua Cheng Zhiyou Jing Haijin Cao Tao Feng | 2022 | Acta Oceanologica Sinica2022，41，4： | 0 |
| 17 | Impacts of Oceanic Fronts and Eddies in the Kuroshio-Oyashio Extension Region on the Atmospheric General Circulation and Storm Track显示文摘This paper reviews the progress in our understanding of the atmospheric response to midlatitude oceanic fronts and eddies,emphasizing the Kuroshio-Oyashio Extension(KOE)region.Oceanic perturbations of interest consist of sharp oceanic fronts,temperature anomalies associated with mesoscale eddies,and to some extent even higher-frequency submesoscale variability.The focus is on the free atmosphere above the boundary layer.As the midlatitude atmosphere is dominated by vigorous transient eddy activity in the storm track,the response of both the time-mean flow and the storm track is assessed.The storm track response arguably overwhelms the mean-flow response and makes the latter hard to detect from observations.Oceanic frontal impacts on the mesoscale structures of individual synoptic storms are discussed,followed by the role of oceanic fronts in maintaining the storm track as a whole.KOE fronts exhibit significant decadal variability and can therefore presumably modulate the storm track.Relevant studies are summarized and intercompared.Current understanding has advanced greatly but is still subject to large uncertainties arising from inadequate data resolution and other factors.Recent modeling studies highlighted the importance of mesoscale eddies and probably even submesoscale processes in maintaining the storm track but confirmation and validation are still needed.Moreover,the atmospheric response can potentially provide a feedback mechanism for the North Pacific climate.By reviewing the above aspects,we envision that future research shall focus more upon the interaction between smaller-scale oceanic processes(fronts,eddies,submesoscale features)and atmospheric processes(fronts,extratropical cyclones etc.),in an integrated way,within the context of different climate background states. | Guidi ZHOU Xuhua CHENG | 2022 | Advances in Atmospheric Sciences2022，39，1： | 0 |
