| 1 | V_r:A new index to represent the variation rate of geomagnetic activity显示文摘By calculating the hourly standard deviation of the first-order differences of the horizontal geomagnetic component minute data,a new index Vr to represent the variation rate of the geomagnetic field was introduced.Vr-indices show similar trends in the temporal change at different observatories and have simultaneous peak values at the observatories covering a large span geographically,which reveals that the source of geomagnetic disturbances represented by Vr is in the magnetosphere.Based on the comparison among Vr,Kp and ap,it is found that generally Vr changes linearly with Kp and ap,which means that the rapid changes of magnetic field usually exist together with magnetic disturbances.But there are exceptions.As Vr can be easily produced by individual observatory in quasi real time and is more sensitive to the variation rate of geomagnetic field rather than the field itself,it can be expected to serve for monitoring or predicting the geomagnetic-induced event in a quick and intuitive way. | Dongmei Yang Yufei He Chuanhua Chen Jiadong Qian | 2010 | Earthquake Science2010，23，4： | 4 |
| 2 | Variations of electron density and temperature in ionosphere based on the DEMETER ISL data显示文摘Observations of the Langmuir Probe Instrument(ISL,Instrument Sonde de Langmuir) onboard the DEMETER satellite during four years from 2006 to 2009 were used to analyze the tempo-spatial variations of electron density(Ne) and temperature(Te) in the ionosphere.Twenty four research bins with each covering an area with 10° in longitude and 2° in latitude were selected to study the spatial distributions of Ne and Te.The results indicate that both Ne and Te have strong annual variations in the topside ionosphere at 660 km altitude.The semiannual anomaly and equinoctial asymmetry which are usually well known as the features of F-layer also exist in the topside ionosphere at low-and mid-latitudes.The yearly variation of Ne is opposite to the peak electron density of the F2-layer(NmF2) at higher latitudes in daytime and both are similar in nighttime.Also the yearly variations of Te at low-latitude are contrary to that at 600 km in daytime and similar in nighttime.An interesting feature of nighttime Te at low-latitude is an obvious annual variation in the northern hemisphere and semiannual variation in the southern hemisphere.The yearly variations of Te in daytime have negative and positive correlation with Ne at mid-and high-latitudes,respectively.Both Ne and Te in the neighborhood bins at the same latitude have a high correlation.In ionospheric events analyzing,this information may help to understand the characteristics of the variation and to distinguish the reliable abnormality from the normal background map. | Yufei He Dongmei Yang Rong Zhu Jiadong Qian M Parrot | 2010 | Earthquake Science2010，23，4： | 1 |
| 3 | Hydrologic implications of the isotopic kinetic fractionation of open-water evaporation显示文摘The kinetic fractionation of open-water evaporation against the stable water isotope H_2 ^(18)O is an important mechanism underlying many hydrologic studies that use ^(18)O as an isotopic tracer. A recent in-situ measurement of the isotopic water vapor flux over a lake indicates that the kinetic effect is much weaker(kinetic factor 6.2‰) than assumed previously(kinetic factor14.2‰) by lake isotopic budget studies. This study investigates the implications of the weak kinetic effect for studies of deuterium excess-humidity relationships, regional moisture recycling, and global evapotranspiration partitioning. The results indicate that the low kinetic factor is consistent with the deuterium excess-humidity relationships observed over open oceans.The moisture recycling rate in the Great Lakes region derived from the isotopic tracer method with the low kinetic factor is a much better agreement with those from atmospheric modeling studies than if the default kinetic factor of 14.2‰ is used. The ratio of transpiration to evapotranspiration at global scale decreases from 84±9%(with the default kinetic factor) to 76±19%(with the low kinetic factor), the latter of which is in slightly better agreement with other non-isotopic partitioning results. | Wei XIAO Yufei QIAN Xuhui LEE Wei WANG Mi ZHANG Xuefa WEN Shoudong LIU Yongbo HU Chengyu XIE Zhen ZHANG Xuesong ZHANG Xiaoyan ZHAO Fucun ZHANG | 2018 | Science China Earth Sciences2018，61，10： | 1 |
| 4 | High-Entropy Perovskite Oxide: A New Opportunity for Developing Highly Active and Durable Air Electrode for Reversible Protonic Ceramic Electrochemical Cells显示文摘Reversible proton ceramic electrochemical cell(R-PCEC)is regarded as the most promising energy conversion device,which can realize efficient mutual conversion of electrical and chemical energy and to solve the problem of large-scale energy storage.However,the development of robust electrodes with high catalytic activity is the main bottleneck for the commercialization of R-PCECs.Here,a novel type of high-entropy perovskite oxide consisting of six equimolar metals in the A-site,Pr_(1/6)La_(1/6)Nd_(1/6)Ba_(1/6)Sr_(1/6)Ca_(1/6)CoO_(3−δ)(PLN-BSCC),is reported as a high-performance bifunctional air electrode for R-PCEC.By harnessing the unique functionalities of multiple ele-ments,high-entropy perovskite oxide can be anticipated to accelerate reaction rates in both fuel cell and electrolysis modes.Especially,an R-PCEC utilizing the PLNBSCC air electrode achieves exceptional electrochemical performances,demonstrating a peak power density of 1.21 W cm^(−2)for the fuel cell,while simultaneously obtaining an astonishing current density of−1.95 A cm^(−2)at an electrolysis voltage of 1.3 V and a temperature of 600℃.The significantly enhanced electrochemical performance and durability of the PLNBSCC air electrode is attributed mainly to the high electrons/ions conductivity,fast hydration reactivity and high configurational entropy.This research explores to a new avenue to develop optimally active and stable air electrodes for R-PCECs. | Zuoqing Liu Zhengjie Tang Yufei Song Guangming Yang Wanru Qian Meiting Yang Yinlong Zhu Ran Ran Wei Wang Wei Zhou Zongping Shao | 2022 | Nano-Micro Letters2022，14，12： | 1 |
| 5 | An overview of cetacean strandings, bycatches and rescues along the western coast of the Taiwan Strait, China: 2010–2015显示文摘The analysis of cetacean strandings can provide fundamental information about species diversity and composition in a particular region. The present study collected and analyzed cetacean strandings, bycatches and rescues along the western coast of the Taiwan Strait, China, from 2010 to 2015. In total, 48 records, including 37 strandings, 8 bycatches and 3 rescues, involving 13 known species were collected. Among them, Indo-Pacific humpback dolphins(Sousa chinensis) and finless porpoises(Neophocaena phocaenoides) were the most common species, consisting of 31.3% and 25%, respectively. Notably, 10 out of the 48(20.8%) records were collected from the Pingtan Island and included 3 species of Mysticeti and 4 species of Odontoceti. Finally, we compared the cetacean species composition between the western and eastern coasts of the Taiwan Strait; 31 cetacean species occurred in the Taiwan Strait, indicating a relatively high cetacean diversity in this region. Systematic field surveys are urgently needed to explore the cetacean species composition, population stock and the related habitat status in the Taiwan Strait, which may improve conservation management in the future. | ZHAO Liyuan ZHU Qian MIAO Xing XU Min WU Fuxing DAI Yufei TAO Cuihua MOU Jianfeng WANG Xianyan | 2017 | Acta Oceanologica Sinica2017，36，12： | 1 |
| 6 | Effects of DOM characteristics from real wastewater on the degradation of pharmaceutically active compounds by the UV/H_(2)O_(2) process显示文摘The characteristics of dissolved organic matter(DOM) can significantly affect the degradation of target compounds by the advanced oxidation processes. In this study, the effects of the different hydrophobicity/hydrophilicity fractions, molecular weight(MW) fractions,fluorescence components and molecular components of DOM extracted from municipal wastewater on the degradation of 4 pharmaceutically active compounds(Ph ACs), including carbamazepine, clofibric acid, atenolol and erythromycin by the UV/H_(2)O_(2) process were investigated. The results showed that the degradation rate constants of 4 Ph ACs decreased dramatically in the presence of DOM. The linear regressions of 4 Ph ACs degradation as a function of specific fluorescence intensity(SFI) are exhibited during the degradation of 4Ph ACs and the SFI may be used to evaluate effect of DOM on target compounds in wastewater. The hydrophobic acid(HPO-A) exhibited the strongest inhibitory effect on degradation of 4 Ph ACs during oxidation process. The small MW fractions of DOM significantly inhibited the degradation of 4 Ph ACs during oxidation process. Among three fluorescence components,hydrophobic humic-like substances may significantly inhibit the degradation of 4 Ph ACs during oxidation process. At the molecular level, the formulas may be derived from terrestrial sources. CHO compound may significantly inhibit the degradation of 4 Ph ACs during oxidation process on formula classes. The unsaturated hydrocarbons, carbohydrates and tannins compounds may significantly inhibit the effectiveness of the UV/H_(2)O_(2) process on compound classes. | Yufei Shi Jinju Geng Xiang Li Yuli Qian Hongzhou Li Liye Wang Gang Wu Qingmiao Yu Ke Xu Hongqiang Ren | 2022 | Journal of Environmental Sciences2022，34，6： | 0 |
| 7 | Influence of mass ratio and calcination temperature on physical and photoelectrochemical properties of ZnFe-layered double oxide/cobalt oxide heterojunction semiconductor for dye degradation applications显示文摘A visible light-active photoelectrocatalyst,ZnFe-layered double oxide(LDO)/cobalt(II,III)oxide(Co_(3)O_(4))composites were obtained by calcining the Co loaded ZnFe-layered double hydroxide(LDH)prepared by a hydrothermal and microwave hydrothermal method.The morphological studies revealed that the ZnFe-LDO/Co_(3)O_(4) composites exhibited a flower-like structure comprising Co_(3)O_(4) nanowires and ZnFe-LDO nanosheets.Further,when the mass ratio of Co(NO_(3))_(2)·6H_(2)O/LDH was 1:1.8 and the calcination temperature was 550℃,the ZnFe-LDO/Co_(3)O_(4) composite exhibited 93.3%degradation efficiency for methylene blue(MB)at the applied voltage of 1.0 V under visible light after 3 h.Furthermore,the Mott-Schottky model experiments showed that the formation of a p-n heterojunction between ZnFe-LDO and Co_(3)O_(4) could effectively inhibit the recombination of electrons and holes in the photoelectrocatalytic process.Meanwhile,free radical scavenging experiments showed that the active radicals of⋅OH played an important role in the degradation of MB.Therefore,the photoelectrocatalytic effect of ZnFe-LDO/Co_(3)O_(4) provides a simple and effective strategy for the removal of organic pollutants. | Yufei Zhang Junjie Zheng Jiejie Nan Chengjie Gai Qian Shao Vignesh Murugadoss Srihari Maganti Nithesh Naik Hassan Algadi Mina Huang Ben Bin Xu Zhanhu Guo | 2023 | Particuology2023，，3： | 0 |
| 8 | Prediction of the thermal conductivity of Mg–Al–La alloys by CALPHAD method显示文摘Mg-Al alloys have excellent strength and ductility but relatively low thermal conductivity due to Al addition.The accurate prediction of thermal conductivity is a prerequisite for designing Mg-Al alloys with high thermal conductivity.Thus,databases for predicting temperature-and composition-dependent thermal conductivities must be established.In this study,Mg-Al-La alloys with different contents of Al2La,Al3La,and Al11La3phases and solid solubility of Al in the α-Mg phase were designed.The influence of the second phase(s) and Al solid solubility on thermal conductivity was investigated.Experimental results revealed a second phase transformation from Al_(2)La to Al_(3)La and further to Al_(11)La_(3)with the increasing Al content at a constant La amount.The degree of the negative effect of the second phase(s) on thermal diffusivity followed the sequence of Al2La>Al3La>Al_(11)La_(3).Compared with the second phase,an increase in the solid solubility of Al in α-Mg remarkably reduced the thermal conductivity.On the basis of the experimental data,a database of the reciprocal thermal diffusivity of the Mg-Al-La system was established by calculation of the phase diagram (CALPHAD)method.With a standard error of±1.2 W/(m·K),the predicted results were in good agreement with the experimental data.The established database can be used to design Mg-Al alloys with high thermal conductivity and provide valuable guidance for expanding their application prospects. | Hongxia Li Wenjun Xu Yufei Zhang Shenglan Yang Lijun Zhang Bin Liu Qun Luo Qian Li | 2024 | International Journal of Minerals,Metallurgy and Materials2024，31，1： | 0 |
| 9 | Feasibility and physics potential of detecting ^(8)B solar neutrinos at JUNO显示文摘The Jiangmen Underground Neutrino Observatory(JUNO)features a 20 kt multi-purpose underground liquid scintillator sphere as its main detector.Some of JUNO's features make it an excellent location for^8B solar neutrino measurements,such as its low-energy threshold,high energy resolution compared with water Cherenkov detectors,and much larger target mass compared with previous liquid scintillator detectors.In this paper,we present a comprehensive assessment of JUNO's potential for detecting^8B solar neutrinos via the neutrino-electron elastic scattering process.A reduced 2 MeV threshold for the recoil electron energy is found to be achievable,assuming that the intrinsic radioactive background^(238)U and^(232)Th in the liquid scintillator can be controlled to 10^(-17)g/g.With ten years of data acquisition,approximately 60,000 signal and 30,000 background events are expected.This large sample will enable an examination of the distortion of the recoil electron spectrum that is dominated by the neutrino flavor transformation in the dense solar matter,which will shed new light on the inconsistency between the measured electron spectra and the predictions of the standard three-flavor neutrino oscillation framework.IfDelta m^(2)_(21)=4.8times10^(-5);(7.5times10^(-5))eV^(2),JUNO can provide evidence of neutrino oscillation in the Earth at approximately the 3sigma(2sigma)level by measuring the non-zero signal rate variation with respect to the solar zenith angle.Moreover,JUNO can simultaneously measureDelta m^2_(21)using^8B solar neutrinos to a precision of 20% or better,depending on the central value,and to sub-percent precision using reactor antineutrinos.A comparison of these two measurements from the same detector will help understand the current mild inconsistency between the value of Delta m^2_(21)reported by solar neutrino experiments and the KamLAND experiment.

| 10 | Steerable merging bound states in the continuum on a quasi-flatband of photonic crystal slabs without breaking symmetry显示文摘Optical resonators with high quality(Q)factors are paramount for the enhancement of light–matter interactions in engineered photonic structures,but their performance always suffers from the scattering loss caused by fabrication imperfections.Merging bound states in the continuum(BICs)provide us with a nontrivial physical mechanism to overcome this challenge,as they can significantly improve the Q factors of quasi-BICs.However,most of the reported merging BICs are found atΓpoint(the center of the Brillouin zone),which intensively limits many potential applications based on angular selectivity.To date,studies on manipulating merging BICs at off-Γpoint are always accompanied by the breaking of structural symmetry that inevitably increases process difficulty and structural defects to a certain extent.Here,we propose a scheme to construct merging BICs at almost an arbitrary point in momentum space without breaking symmetry.Enabled by the topological features of BICs,we merge four accidental BICs with one symmetry-protected BIC at theΓpoint and merge two accidental BICs with opposite topological charges at the off-Γpoint only by changing the periodic constant of a photonic crystal slab.Furthermore,the position of off-Γmerging BICs can be flexibly tuned by the periodic constant and height of the structure simultaneously.Interestingly,it is observed that the movement of BICs occurs in a quasi-flatband with ultra-narrow bandwidth.Therefore,merging BICs in a tiny band provide a mechanism to realize more robust ultrahigh-Q resonances that further improve the optical performance,which is limited by wide-angle illuminations.Finally,as an example of application,effective angle-insensitive second-harmonic generation assisted by different quasi-BICs is numerically demonstrated.Our findings demonstrate momentum-steerable merging BICs in a quasi-flatband,which may expand the application of BICs to the enhancement of frequency-sensitive light–matter interaction with angular selectivity. | XIN QI JIAJU WU FENG WU MINA REN QIAN WEI YUFEI WANG HAITAO JIANG YUNHUI LI ZHIWEI GUO YAPING YANG WANHUA ZHENG YONG SUN HONG CHEN | 2023 | Photonics Research2023，11，7： | 0 |
| 11 | Anomaly of the ionospheric electron density close to earthquakes:Case studies of Pu'er and Wenchuan earthquakes显示文摘The electron density recorded onboard the DEMETER satellite was analyzed to search for possible anomalies before earthquakes both in space and time.To distinguish pre-earthquake anomalies from the other anomalies related to geomagnetic activity,data were filtered using the K_p index.The analysis is based on the comparison of data recorded closely to earthquakes in space and time and past data for the same area.In analyzing data around the time and location of the Pu'er and Wenchuan earthquakes,obvious anomalies in electron density were found close to the epicenters,and some remarkable disturbances were detected before the earthquakes occurred.The results were finally compared with those of previous works that used the same data but employed different analysis methods.Good agreement was found which suggests that these anomalies have a close relation to the earthquake preparation. | Yufei He Dongmei Yang Jiadong Qian Michel Parrot | 2011 | Earthquake Science2011，24，6： | 0 |
| 12 | Water molecules bonded to the carboxylate groups at the inorganic-organic interface of an inorganic nanocrystal coated with alkanoate ligands显示文摘High-quality colloidal nanocrystals are commonly synthesized in hydrocarbon solvents with alkanoates as the most common organic ligand.Water molecules with an approximately equal number of surface alkanoate ligands are identified at the inorganic-organic interface for all types of colloidal nanocrystals studied,and investigated quantitatively using CdSe nanocrystals as the model system.Carboxylate ligands are coordinated to the surface metal ions and the first monolayer of water molecules is found to bond to the carboxylate groups of alkanoate ligands through hydrogen bonds.Additional monolayer(s)of water molecules can further be adsorbed through hydrogen bonds to the first monolayer of water molecules.The nearly ideal environment for hydrogen bonding at the inorganic-organic interface of alkanoate-coated nanocrystals helps to rapidly and stably enrich the interface-bonded water molecules,most of which are difficult to remove through vacuum treatment,thermal annealing and chemical drying.The water-enriched structure of the inorganic-organic interface of high-quality colloidal nanocrystals must be taken into account in order to understand the synthesis,processing and properties of these novel materials. | Jiongzhao Li Weicheng Cao Yufei Shu Haibing Zhang Xudong Qian Xueqian Kong Linjun Wang Xiaogang Peng | 2022 | National Science Review2022，9，2： | 0 |
| 13 | A developed dual-site Langmuir model to represent the high-pressure methane adsorption and thermodynamic parameters in shale显示文摘Comprehending the mechanism of methane adsorption in shales is a crucial step towards optimizing the development of deep-buried shale gas. This is because the methane adsorbed in shale represents a significant proportion of the subsurface shale gas resource. To properly characterize the methane adsorption on shale, which exhibits diverse mineral compositions and multi-scale pore sizes, it is crucial to capture the energy heterogeneity of the adsorption sites. In this paper, a dual-site Langmuir model is proposed, which accounts for the temperature and pressure dependence of the density of the adsorbed phase. The model is applied to the isothermals of methane adsorption on shale, at pressures of up to 30 MPa and temperatures ranging from 40 to 100 ℃. The results show that the proposed model can describe the adsorption behavior of methane on shale more accurately than conventional models, which assume a constant value for the density of adsorbed phase. Furthermore, the proposed model can be extrapolated to higher temperatures and pressures. Thermodynamic parameters were analyzed using correctly derived equations. The results indicate that the widely used, but incorrect, equation would underestimate the isosteric heat of adsorption. Neglecting the real gas behavior, volume of the adsorbed phase, and energy heterogeneity of the adsorption sites can lead to overestimation of the isosteric heat of adsorption. Furthermore, the isosteric heat evaluated from excess adsorption data can only be used to make a rough estimate of the real isosteric heat at very low pressure. | Ke Hu Qian Zhang Yufei Liu Muhammad Abdurrahman Thaika | 2023 | International Journal of Coal Science & Technology2023，10，5： | 0 |
| 14 | LAT1 targeted brain delivery of temozolomide and sorafenib for effective glioma therapy显示文摘Glioma is the most common primary craniocerebral tumor caused by the cancerous growth of glial cells in the brain and spinal cord.Currently,standard treatment is the surgical resection followed by concurrent radiation and chemotherapy.However,the blood-brain barrier(BBB)prevents most antitumor drugs from entering the brain and reduces their efficacy,especially in lowgrade glioma.Since L-type amino acid transporter 1(LAT1)is highly expressed in glioma cells and mediates drug transport across the BBB,it is a promising target for drug delivery and treatment of glioma.Temozolomide(TMZ)is the first-line treatment for glioma,however,patients often exhibit drug resistance at advanced stage.A multikinase inhibitor and inducer of ferroptosis,sorafenib can improve the therapeutic effects of TMZ.Therefore,to optimize the glioma treatment and cross the BBB,we designed LAT1-targeting nanoparticles co-loaded with TMZ and sorafenib.Our results from both in vitro and in vivo studies confirmed that LAT1-targeting nanoparticles significantly increased the cellular uptake,cytotoxicity,accumulation at tumor site,and the anti-tumor efficacy compared to the non-target nanoparticles.Therefore,LAT1 can be used as a potential target for braintargeted drug delivery,and sorafenib-induced ferroptosis can aid the anti-glioma efficacy of TMZ. | Yufei Zhang Qian Cheng Yuhao Xue Kai Yao Madiha Zahra Syeda Jian Xu Jianheng Wu Zhenjie Wang Longguang Tang Qingchun Mu | 2023 | Nano Research2023，16，7： | 0 |
| 15 | Mesoporous Cu_(3−x)Zn_(x)(BTC)_(2)nanocubes synthesized in deep eutectic solvent and their catalytic performances显示文摘To develop high-performance metal-organic frameworks(MOFs)for catalysis is of great importance.Here,we synthesized the mesoporous Cu_(3−x)Zn_(x)(BTC)_(2)(BTC=benzene-1,3,5-tricarboxylate)nanocubes in a deep eutectic solvent of ZnCl_(2)/ethylene glycol solution.The route can proceed at room temperature and the reaction time needed is shortened to be 30 min,which is superior to the conventional solvothermal route that usually needs high temperature and long reaction time.The formation mechanism of the mesoporous Cu_(3−x)Zn_(x)(BTC)_(2)nanocubes in deep eutectic solvent(DES)was investigated by in situ synchrotron X-ray diffraction/small angle X-ray scattering/X-ray absorption fine structure conjunction technique.The mesoporous Cu_(3−x)Zn_(x)(BTC)_(2)nanocubes exhibit high catalytic activity and reusability for cyanosilylation reaction of benzaldehyde and aerobic oxidation reaction of benzylic alcohol. | Jingyang Hu Jianling Zhang Xiuniang Tan Xiuyan Cheng Zhuizhui Su Lixiong Qian Mingzhao Xu Yufei Sha Yanyue Wang Yisen Yang Yunpeng Liu Guang Mo Xueqing Xing Zhonghua Wu | 2023 | Nano Research2023，16，3： | 0 |
