| 1 | Synthesis of Li_4Ti_5O_(12) nanostructural anode materials with high charge–discharge capability显示文摘This study demonstrates a facile and efficient hydrothermal method to prepare spindle titanate(Li4Ti5O12 denoted as LTO)and/or carbon-LTO nanocomposites(CLTO),in which the LTO or C-LTO microspheres have diameters of a few micrometers,composed of numerous nanosheets with thickness of*30 nm and edge length of hundreds of nanometers.The morphology and size control of these nanoparticles could be achieved by varying experimental parameters including concentration of titanium butoxide,lithium hydroxide,and cetyltrimethylammonium bromide,as well as reaction temperature and time.These micro-nanostructures were characterized by several advanced techniques,such as transmission electron microscopy,scanning electron microscopy,X-ray diffraction,energy dispersive spectroscopic analysis,surface area,and electrochemical measurements.The LTO and C-LTO microstructures were examined in the charge–discharge capacity at a rate of 50 C,as well as the stability after 100 cycles at a rate of 10 C.The excellent capability may be attributed to good conductivity,large surface area,and stable assembly structure of such micro-nanostructures,which could be explored as a promising anode material for lithium-ion batteries. | Ru Wen Jeffrey Yue Zifeng Ma Wuming Chen Xuchuan Jiang Aibing Yu | 2014 | Chinese Science Bulletin2014，59，18： | 8 |
| 2 | Hierarchical peony-like FeCo-NC with conductive network and highly active sites as efficient electrocatalyst for rechargeable Zn-air battery显示文摘Carbon materials featuring hierarchical pores and atomically dispersed metal sites are promising catalysts for energy storage and conversion applications.Herein,we developed a facile strategy to construct functional carbon materials with a fluffy peony-like structure and dense binary FeCo-Nx active sites(termed as f-FeCo-CNT).By regulating the metal content in precursors,a three-dimensional(3D)interconnected conductive carbon nanotubes network was in-situ formed throughout the atomically dispersed FeCo-NC matrix during pyrolysis.Taking advantage of rich pore hierarchy and co-existence of highly active FeCo-Nx sites and beneficial FeCo alloy nanoparticles,the f-FeCo-CNT material exhibited excellent bifunctional performance towards oxygen reduction reaction/oxygen evolution reactions(ORR/OER)with respect to the atomically dispersed FeCo-NC(SA-f-FeCo-NC)and commercial Pt/C+Ru02 mixture,surpassing the SA-f-FeCo-NC with a 20 mV higher ORR half-wave potential and a 100 mV lower OER overpotential(at 10.0 mA/cm^2).Remarkably,the f-FeCo-CNT-assembled Zn-air battery(ZAB)possessed a maximum specific power of 195.8 mW/cm^2,excellent rate capability,and very good cycling stability at large current density of 20.0 mA/cm^2.This work provides a facile and feasible synthetic strategy of constructing low-cost cathode materials with excellent comprehensive ZAB performance. | Yiyan Wang Anuj Kumar Mang Ma Yin Jia Yu Wang Ying Zhang Guoxin Zhang Xiaoming Sun Zifeng Yan | 2020 | Nano Research2020，13，4： | 5 |
| 3 | RECENT ADVANCES IN RESEARCH AND FORECASTING OF TROPICAL CYCLONE TRACK, INTENSITY, AND STRUCTURE AT LANDFALL显示文摘This review prepared for the fourth International Workshop on Tropical Cyclone Landfall Processes(IWTCLP-4) summarizes the most recent(2015-2017) theoretical and practical knowledge in the field of tropical cyclone(TC) track, intensity, and structure rapid changes at or near landfall. Although the focus of IWTCLPIV was on landfall, this summary necessarily embraces the characteristics of storms during their course over the ocean prior to and leading up to landfall. In the past few years, extremely valuable observational datasets have been collected for TC forecasting guidance and research studies using both aircraft reconnaissance and new geostationary or low-earth orbiting satellites at high temporal and spatial resolution. Track deflections for systems near complex topography such as that of Taiwan and La Réunion have been further investigated, and advanced numerical models with high spatial resolution necessary to predict the interaction of the TC circulation with steep island topography have been developed. An analog technique has been designed to meet the need for longer range landfall intensity forecast guidance that will provide more time for emergency preparedness. Probabilistic track and intensity forecasts have also been developed to better communicate on forecast uncertainty. Operational practices of several TC forecast centers are described herein and some challenges regarding forecasts and warnings for TCs making landfall are identified. This review concludes with insights from both researchers and forecasters regarding future directions to improve predictions of TC track, intensity, and structure at landfall. | MARIE-DOMINIQUE LEROUX KIMBERLY WOOD RUSSELL L.ELSBERRY ESPERANZA O.CAYANAN ERIC HENDRICKS MATTHEW KUCAS PETER OTTO ROBERT ROGERS BUCK SAMPSON ZIFENG YU | 2018 | Tropical Cyclone Research and Review2018，7，2： | 4 |
| 4 | One-pot synthesis of the highly efficient bifunctional Ni-SAPO-11 catalyst显示文摘Hydro isomerization of linear alkanes to branched isomers is an important petrochemical process for production of gasoline with high octane number.Non-noble metal bifunctional catalysts used in this process always suffer from low metal dispersion and poor metal-acid synergy.Herein,a facile one-pot synthesis method was used to simultaneously regulate metal particle sizes and acidity of the Ni-SAPO-11 hydroisomerization catalyst.The physicochemical properties are investigated using XANES,EXAFS,TEM/STEM,FT-IR,XPS,UV-vis and NH_3-TPD.Apart from the highly dispersed nickel nanoparticles with an average diameter of 8 nm,the framework Ni~(2+)ions are generated via substituting framework Al~(3+)ions of the SAPO-11.The formed NiP-OH structures have lower deprotonation energy(DPE)than the SiAl-OH ones,contributing more and stronger acid sites to the Ni-SAPO-11 catalyst.The great metal-acid synergy including high metal to acid sites ratio(n_(Ni)/n_A)and close intimacy is obtained for the Ni-SAPO-11 catalyst.The Ni-SAPO-11 catalyst outperforms the counterpart prepared by the impregnation method and exhibits comparable activity and isomers selectivity to the Pt/SAPO-11 catalyst in the n-hexane hydroisomerization. | Yuchao Lyu Weilong Zhan Zhumo Yu Xinmei Liu Ye Yang Xiaoxing Wang Chunshan Song Zifeng Yan | 2021 | Journal of Materials Science & Technology2021，，17： | 4 |
| 5 | Ag@Au core/shell triangular nanoplates with dual enzyme-like properties for the colorimetric sensing of glucose显示文摘Due to the serious harm of diabetes to human health,development of sensitive assays for glucose level is of high significance for early prevention and treatment of diabetes.Currently,most conventional enzyme-based glucose sensors suffer from high cost and low stability due to the inherent defects of natural enzymes.Herein,we develop a pure nanozyme-based glucose detection method using Ag@Au core/shell triangular nanoplates(TNPs),which combines glucose oxidase(GOD)-and horseradish peroxidase(HRP)-like activities of the Au shell and inherent plasmonic properties of Ag TNPs.The sensing mechanism is based on the fact that the Au shell possessed GOD-like activity,enabling the oxidation of glucose to produce H2O2,which can further etch the silver core,leading to the decrease of absorbance at 800 nm and the color change from blue to colorless.Compared with the previous nanozymes-based glucose sensors,our method avoids the use of enzymes and organic chromogenic agent.Moreover,the stability of the Ag@Au core/shell TNPs is much better than that of Ag TNPs due to the protection by the coating of the Au shell.This method was successfully applied to the detection of urine samples from patients with diabetes,indicating its practical applicability for real sample analysis. | Ao Liu Mengmeng Li Jingxiang Wang Fan Feng Yu Zhang Zhiwei Qiu Yuzhu Chen Benjamin Edem Meteku Congying Wen Zifeng Yan Jingbin Zeng | 2020 | Chinese Chemical Letters2020，31，5： | 3 |
| 6 | OVERVIEW OF SEVERE TYPHOON FITOW AND ITS OPERATIONAL FORECASTS显示文摘Severe typhoon Fitow(1323)brought persistent and heavy rainfall to Zhejiang and the Shanghai area after it made landfall at Fujian Province of China in October 2013,breaking the rainfall records of several counties and districts in Zhejiang.In this paper,we provide an overview of the characteristics of Fitow’s landfall,including its track,intensity,structural evolution,heavy rainfall,and wind.We also describe some of the associated disastrous impacts.Finally,we provide verifications of operational forecasts of its track,intensity and rainfall.Though the track and intensity is well predicted,the rainfall persistence and enhancement in the second stage in Shanghai and north Zhejiang areas are not predicted out at all.The analysis presented in this paper provides forecasters and researchers with some valuable information on Fitow,which could form a useful basis for further studies. | ZIFENG YU YANDIE CHEN DAN WU GUOMIN CHEN XUWEI BAO QIUZHEN YANG RUNLING YU LEI ZHANG JIE TANG MING XU ZHIHUA ZENG | 2014 | Tropical Cyclone Research and Review2014，3，1： | 2 |
| 7 | Validation and Spatiotemporal Distribution of GEOS-5-Based Planetary Boundary Layer Height and Relative Humidity in China显示文摘Few studies have specifically focused on the validation and spatiotemporal distribution of planetary boundary layer height(PBLH) and relative humidity(RH) data in China. In this analysis, continuous PBLH and surface-level RH data simulated from GEOS-5 between 2004 and 2012, were validated against ground-based observations. Overall, the simulated RH was consistent with the statistical data from meteorological stations, with a correlation coefficient of 0.78 and a slope of 0.9. However, the simulated PBLH was underestimated compared to LIDAR data by a factor of approximately two,which was primarily because of poor simulation in late summer and early autumn. We further examined the spatiotemporal distribution characteristics of two factors in four regions—North China, South China, Northwest China, and the Tibetan Plateau. The results showed that the annual PBLH trends in all regions were fairly moderate but sensitive to solar radiation and precipitation, which explains why the PBLH values were ranked in order from largest to smallest as follows: Tibetan Plateau, Northwest China, North China, and South China. Strong seasonal variation of the PBLH exhibited high values in summer and low values in winter, which was also consistent with the turbulent vertical exchange. Not surprisingly, the highest RH in South China and the lowest RH in desert areas of Northwest China(less than 30%). Seasonally, South China exhibited little variation, whereas Northwest China exhibited its highest humidity in winter and lowest humidity in spring,the maximum values in the other regions were obtained from July to September. | Yidan SI Shenshen LI Liangfu CHEN Chao YU Zifeng WANG Yang WANG Hongmei WANG | 2018 | Advances in Atmospheric Sciences2018，35，4： | 2 |
| 8 | Scalable synthesis of Na_(3)V_(2)(PO_(4))_(3)/C with high safety and ultrahigh-rate performance for sodium-ion batteries显示文摘NASICON-type Na_(3)V_(2)(PO_(4))_(3) is a promising electrode material for developing advanced sodium-ion batteries.Preparing Na_(3)V_(2)(PO_(4))_(3) with good performance by a cost-effective and large-scale method is significant for industrial applications.In this work,a porous Na_(3)V_(2)(PO_(4))_(3)/C cathode material with excellent electrochemical performance is successfully prepared by an agar-gel combined with freeze-drying method.The Na_(3)V_(2)(PO_(4))_(3)/C cathode displayed specific capacities of 113.4 mAh·g^(-1),107.0 mAh·g^(-1) and 87.1 mAh·g^(-1) at 0.1 C,1 C and 10 C,respectively.For the first time,the 500-mAh soft-packed symmetrical sodium-ion batteries based on Na_(3)V_(2)(PO_(4))_(3)/C electrodes are successfully fabricated.The 500-mAh symmetrical batteries exhibit outstanding low temperature performance with a capacity retention of 83%at 0℃ owing to the rapid sodium ion migration ability and structural stability of Na_(3)V_(2)(PO_(4))_(3)/C.Moreover,the thermal runaway features are revealed by accelerating rate calorimetry(ARC)test for the first time.Thermal stability and safety of the symmetrical batteries are demonstrated to be better than lithium-ion batteries and some reported sodium-ion batteries.Our work makes it clear that the soft-packed symmetrical sodium ion batteries based on Na_(3)V_(2)(PO_(4))_(3)/C have a prospect of practical application in high safety requirement fields. | Guijia Cui Hong Wang Fengping Yu Haiying Che Xiaozhen Liao Linsen Li Weimin Yang Zifeng Ma | 2022 | Chinese Journal of Chemical Engineering2022，35，6： | 2 |
| 9 | Crucial control measures to contain China's first Delta variant outbreak显示文摘The SARS-C oV-2 B.1.617.2(Delta) variant flared up in late May in Guangzhou,China.Transmission characteristics of Delta variant were analysed for 153 confirmed cases and two complete transmission chains with seven generations were fully presented.A rapid transmission occurred in five generations within10 days.The basic reproduction number(R_0) was 3.60(95% confidence interval:2.50-5.30).After redefining the concept of close contact,the proportion of confirmed cases discovered from close contacts increased from 43% to 100%.With the usage of a yellow health code,the potential exposed individuals were self-motivated to take a nucleic acid test and regained public access with a negative testing result.Facing the massive requirement of screening,novel facilities like makeshift inflatable laboratories were promptly set up as a vital supplement and 17 cases were found,with 1 pre-symptomatic.The dynamic adjustment of these three interventions resulted in the decline of Rt from 5.00 to 1.00 within 9 days.By breaking the transmission chain and eliminating the transmission source through extending the scope of the close-contact tracing,health-code usage and mass testing,the Guangzhou D elta epidemic was effectively contained. | Lei Luo Zifeng Yang Jingyi Liang Yu Ma Hui Wang Chitin Hon Mei Jiang Zhengshi Lin Wenda Guan Zhitong Mai Yongming Li Kailin Mai Zhiqi Zeng Chuanmeizi Tu Jian Song Bin Liu Yong Liu Jianfeng He Huiyuan Li Bosheng Li Hang Dong Yutian Miao Shujun Fan Lirui Fan Xingyi Liang Ke Li Chun Chen Huihong Deng Zhicong Yang Nanshan Zhong | 2022 | National Science Review2022，9，4： | 2 |
| 10 | Morphology and phylogeny of Chrysogorgia pinniformis sp.nov.and C.varians sp.nov.,two golden corals from the Caroline seamounts in the tropical Western Pacific Ocean显示文摘Two new species of Chrysogorgia Duchassaing&Michelotti,1864 collected from the Caroline seamounts in the tropical Western Pacific Ocean are described.Chrysogorgia pinniformis sp.nov.belongs to Versluys’group C(Squamosae typicae)with only scales in polyp body wall and tentacles.C.pinniformis sp.nov.is characterized by large branches pinnately branched and forming multiple fans with its small branches regularly and quasi-dichotomous branched,and scales and rods present in the polyp mouth area.It is most similar to C.pinnata Cairns,2007 by the pinnate trait,but differs from the latter by its group C pattern(vs.group A,Spiculosae)and having sclerites present in the polyp mouth area(vs.absent).Chrysogorgia varians sp.nov.belongs to the Chrysogorgia group A(Spiculosae)with rods distributed in the polyp body wall and tentacles.It is characterized by warty rods and elongated scales in the tentacles,many warts and ridges on the scales,conspicuously toothed margins at the rounded ends in the pinnules,and small rods with ridge-like warts in the polyp mouth area.This species was frequent and abundant in the Caroline seamounts during our cruises and its morphological variability in growth period was obvious.The phylogenetic analyses based on mtMutS and 28 S rDNA regions supported the assignment of the new species to the genus Chrysogorgia.However,the mtMutS marker showed very limited usefulness for species delimitation and inner relationship inference of Chrysogorgia.In contrast,the 28 S rDNA showed much higher level of genetic variation,and it may be a potential barcode for this genus.In the 28 S rDNA trees,the two new species clustered together.Additionally,compilation of our data showed that 42 of 78(ca.54%)Chrysogorgia species were found in the Indo-West Pacific convergent region,indicating that this area may be a hotspot of deep-water Chrysogorgia species. | Yu XU Zifeng ZHAN Kuidong XU | 2021 | Journal of Oceanology and Limnology2021，39，5： | 1 |
| 11 | Rainfall forecast errors in different landfall stages of Super Typhoon Lekima (2019)显示文摘The rainfall forecast performance of the Tropical Cyclone(TC)version Model of Global and Regional Assimilation PrEdiction System(GRAPESTCM)of the China Meteorological Administration for landfalling Super Typhoon Lekima(2019)is studied by using the object-oriented verification method of contiguous rain area(CRA).The major error sources and possible reasons for the rainfall forecast uncertainties in different landfall stages(including near landfall and moving further inland)are compared.Results show that different performance and errors of rainfall forecast exist in the different TC stages.In the near landfall stage the asymmetric rainfall distribution is hard to be simulated,which might be related to the too strong forecasted TC intensity and too weak vertical wind shear accompanied.As Lekima moves further inland,the rain pattern and volume errors gradually increase.The Equitable Threat Score of the 24 h forecasted rainfall over 100 mm declines quickly with the time-length over land.The diagnostic analysis shows that there exists an interaction between the TC and the mid-latitude westerlies,but too weak frontogenesis is simulated.The results of this research indicate that for the current numerical model,the forecast ability of persistent heavy rainfall is very limited,especially when the weakened landing TC moves further inland. | Bin HE Zifeng YU Yan TAN Yan SHEN Yingjun CHEN | 2022 | Frontiers of Earth Science2022，16，1： | 1 |

| 13 | Luminescent d-f transition Yb(Ⅱ)-containing azacryptates with high photoluminescence quantum yields显示文摘Emission tunable d-f transition lanthanide complexes have wide applications in many fields such as lighting and photoredox catalysis.Compared with Ce(Ⅲ)and Eu(Ⅱ)complexes,which have achieved near-unity photoluminescence quantum yields(PLQYs),Yb(Ⅱ)complexes still suffer from low reported PLQYs not exceeding 10%.In this work,two luminescent Yb(Ⅱ)-containing azacryptates YbI_(2)-N8M6(N8M6=4,7,13,16,21,24-hexamethyl-1,4,7,10,13,16,21,24-octaazabicyclo[8.8.8]hexacosane)and YbI2-N8E6(N8E6=4,7,13,16,21,24-hexaethyl-1,4,7,10,13,16,21,24-octaazabicyclo[8.8.8]hexacosane)were synthesized and characterized.YbI2-N8M6 in solid powder exhibits blue emission with a maximum emission wavelength(λm)of 464 nm and a PLQY of 76%,while YbI_(2)-N8E6 in solid powder exhibits green emission with a λ_(m) of 537 nm and a PLQY up to93%.Moreover,YbI_(2)-N8M6 exhibits mechanochromic property,showing an emission color change from deep-blue to cyan under mechanical grinding.These results will inspire the studies about luminescent Yb(Ⅱ)complexes and their further applications. | Wenchao Yan Zifeng Zhao Gang Yu Hao Qi Ruoyao Guo Nanlong Zheng Zuqiang Bian Zhiwei Liu | 2023 | Science China Chemistry2023，66，6： | 0 |
| 14 | Satellite record of the transition of air quality over China显示文摘The rapid development of atmospheric satellite instruments since 1990s provides unprecedented large amount of observational datasets concerning global atmospheric pollutants.The continu-ous and long-term large-scale satellite products such as aerosol optical depth,tropospheric NO 2 and SO 2 enable effective and objective evaluation of air quality.Satellite columnar aerosol opti-cal parameters can be used to indicate particle pollution near surface after correction.By contrast,satellite results of trace gas pollutants such as NO 2 and SO 2 from fossil fuel combustion with short lifetime around half one day are used to estimate anthro-pogenic emissions.It is shown that the overall anthropogenic emissions in China have largely declined since strict emission reduction policy implemented since 2013.However,coarse pixel resolution of the trace gases,limited information and retrieval bias of aerosol properties tend to hinder further application of satellite in air quality research.Recently launched satellite missions with advanced detection abilities will greatly enhance global atmo-spheric observations with much more datasets available. | Liangfu Chen Minghui Tao Zifeng Wang Jinhua Tao Chao Yu Ying Zhang Meng Fan Jinabin Gu Lin Su | 2018 | Big Earth Data2018，2，2： | 0 |
| 15 | Metallogenic Age and Ore-forming Material Sources of the Dahongshan Fe-Cu Deposit,Yunnan Province:Insights from Molybdenite Re-Os Dating and H-O-S-Pb Isotopes显示文摘The Dahongshan Fe-Cu(-Au)deposit is a superlarge deposit in the Kangdian metallogenic belt,southwestern China,comprising approximately 458 Mt of Fe ores(40%Fe)and 1.35 Mt Cu.Two main types of Fe-Cu(-Au)mineralization are present in the Dahongshan deposit:(1)early submarine volcanic exhalation and sedimentary mineralization characterized by strata-bound fine-grained magnetite and banded Fe-Cu sulfide(pyrite and chalcopyrite)hosted in the Na-rich metavolcanic rocks;(2)late hydrothermal(-vein)type mineralization characterized by Fe-Cu sulfide veins in the hosted strata or massive coarse-grained magnetite orebodies controlled by faults.While previous studies have focused primarily on the early submarine volcanic and sedimentary mineralization of the deposit,data related to late hydrothermal mineralization is lacking.In order to establish the metallogenic age and ore-forming material source of the late hydrothermal(-vein)type mineralization,this paper reports the Re-Os dating of molybdenite from the late hydrothermal vein Fe-Cu orebody and H,O,S,and Pb isotopic compositions of the hydrothermal quartz-sulfide veins.The primary aim of this study was to establish the metallogenic age and ore-forming material source of the hydrothermal type orebody.Results show that the molybdenite separated from quartz-sulfide veins has a Re-Os isochron age of 831±11 Ma,indicating that the Dahongshan Fe-Cu deposit experienced hydrothermal superimposed mineralization in Neoproterozoic.The molybdenite has a Re concentration of 99.7-382.4 ppm,indicating that the Re of the hydrothermal vein ores were primarily derived from the mantle.The δ^(34)S values of sulfides from the hydrothermal ores are 2‰-8‰ showing multi-peak tower distribution,suggesting that S in the ore-forming period was primarily derived from magma and partially from calcareous sedimentary rock.Furthermore,the abundance of radioactive Pb increased significantly from ore-bearing strata to layered and hydrothermal vein ores,which may be related to the later hydrothermal transformation.The composition of H and O isotopes within the hydrothermal quartz indicates that the ore-forming fluid is a mixture of magmatic water and a small quantity of water.These results further indicate that the late hydrothermal orebodies were formed by the Neoproterozoic magmatic hydrothermal event,which might be related to the breakup of the Rodinia supercontinent.Mantle derived magmatic hydrothermal fluid extracted ore-forming materials from the metavolcanic rocks of Dahongshan Group and formed the hydrothermal(-vein)type Fe-Cu orebodies by filling and metasomatism. | YE Zifeng YANG Guangshu YU Wenxiu CHEN Aibing JIA Fuju | 2023 | Acta Geologica Sinica(English Edition)2023，97，6： | 0 |
| 16 | RAPID INTENSIFICATION NEAR LANDFALL OF TYPHOON VICENTE(2012)显示文摘Typhoon Vicente(2012) underwent rapid intensification(RI) within 24 h before landfall in China's Mainland. Analysis of the large-scale environment and characteristics of Vicente identifies the aforementioned intensification as classic RI. The process occurred in an environmental flow with a deep-layer shear ranging from 5 ms-1 to 8 ms-1. Convection caused by persistent vertical shear forcing of the vortex was observed primarily in the downshear left quadrant of the storm. However, radar and satellite observations indicate that the northern convection of the inner core of Vicente quickly developed in the down-shear right three hours near landfall. | ZIFENG YU DAN WU HUI YU | 2013 | Tropical Cyclone Research and Review2013，2，1： | 0 |
| 17 | RECENT ADVANCES IN RESEARCH AND FORECASTING OF TROPICAL CYCLONE RAINFALL显示文摘In preparation for the Fourth International Workshop on Tropical Cyclone Landfall Processes(IWTCLP-IV), a summary of recent research studies and the forecasting challenges of tropical cyclone(TC) rainfall has been prepared. The extreme rainfall accumulations in Hurricane Harvey(2017) near Houston, Texas and Typhoon Damrey(2017) in southern Vietnam are examples of the TC rainfall forecasting challenges. Some progress is being made in understanding the internal rainfall dynamics via case studies. Environmental effects such as vertical wind shear and terrain-induced rainfall have been studied, as well as the rainfall relationships with TC intensity and structure. Numerical model predictions of TC-related rainfall have been improved via data assimilation, microphysics representation, improved resolution, and ensemble quantitative precipitation forecast techniques. Some attempts have been made to improve the verification techniques as well. A basic forecast challenge for TC-related rainfall is monitoring the existing rainfall distribution via satellite or coastal radars, or from over-land rain gauges. Forecasters also need assistance in understanding how seemingly similar landfall locations relative to the TC experience different rainfall distributions. In addition, forecasters must cope with anomalous TC activity and landfall distributions in response to various environmental effects. | KEVIN CHEUNG ZIFENG YU RUSSELL L.ELSBERRY MICHAEL BELL HAIYAN JIANG TSZ CHEUNG LEE KUO-CHEN LU YOSHINORI OIKAWA LIANGBO QI ROBERT F.ROGERS KAZUHISA TSUBOKI | 2018 | Tropical Cyclone Research and Review2018，7，2： | 0 |
| 18 | Magnetic rod-based metal-organic framework metal composite as multifunctional nanostirrer with adsorptive,peroxidase-like and catalytic properties显示文摘Although magnetic stirring is frequently used to enhance the kinetics for adsorption,chemical and biochemical reactions,the introduction of stirrers inevitably leads to the adsorption of analytes and thus interferes with the efficiency of the chemical process or reaction.In this work,magnetic Fe_(3) O_(4) nanorods with tunable length-to-diameter ratio were synthesized via a hydrothermal method and used as templates for the in-situ depositing of MIL-100(Fe) and gold nanoparticles.Such nanorod-based material can not only function as an adsorbent,nanozyme,and a heterogeneous catalyst for corresponding applications but also serve as a magnetic nanostirrer to enhance kinetics.As a proof-of-concept,the capture of bacteria pathogen,mimic-peroxidase-based colorimetric detection of hydrogen peroxide,and the catalytic reduction of selected organic pollutants were conducted using the as-synthesized Fe_(3) O_(4)@MIL-100(Fe)-Au nanostirrer with and without magnetic field.The results show that the rates of bacteria capture,mimetic enzyme reaction and catalysis were tremendously expedited.We believe this magnetic field-assisted approach holds great promise for future applications,because,not only does it eliminate the use of external magnetic stirrers and thereby decrease the risk of foreign pollution but also,is adaptable for nanoscale reaction systems where conventional stirring is not applicable due to size limitations. | Benjamin Edem Meteku Jiankun Huang Jingbin Zeng Sobia Aslam Yu Zhang Xue Zhang Bingwen Cui Cong-ying Wen Zifeng Yan | 2021 | Chinese Chemical Letters2021，32，10： | 0 |
| 19 | Ecological Investigation and Ecological Security Assessment of Xizhijiang River Basin in Huizhou City of Guangdong Province显示文摘In addition to such ecological problems as the pollution of the water system,the unreasonable structure of the upstream Basin and the insufficient water conservation forests,the Xizhi River Basin also faces human decision-making problems such as imperfect ecological compensation mechanism.In view of the above problems,using the DPSIR model(Drivers,Pressures,States,Impacts,Responses),this paper analyzed eucalyptus forest in Xizhi River Basin to assess the security of the Xizhi River ecological Basin,and finally concluded that the ecological status of Xizhi River Basin remains safe. | Jianqiao QIN Zifeng HE Jianmei CHEN Xiaoping HUANG Dongni YU Shaoli WU | 2021 | Asian Agricultural Research2021，13，2： | 0 |
| 20 | The wheat sucrose synthase gene TaSus1 is a determinant of grain number per spike显示文摘Some haplotypes of the sucrose synthase gene TaSus1 are associated with thousand-grain weight(TGW)in wheat(Triticum aestivum L.).However,no mutations have been identified within the gene to test this association.The effects of TaSus1 on grain number per spike(GNS)also are largely unknown.Our previous genome-wide association study identified TaSus-A1 as a candidate gene controlling fertile spikelet number per spike(FSN).In the present study,we generated two independent mutants for the three TaSus1 homoeologs by CRISPR/Cas9-mediated genome editing.The triple mutants displayed lower FSN,GNS,grain number per spikelet(GNST),and TGW than wild-type plants.In 306 hexaploid wheat accessions,two single-nucleotide polymorphisms in TaSus-A1 contributed differently to GNS.Introgression of the two alleles into a wheat genetic background confirmed their effects.The alleles differed in geographical distribution among the accessions. | Liping Shen Lili Zhang Changbin Yin Xiaowan Xu Yangyang Liu Kuocheng Shen He Wu Zhiwen Sun Ke Wang Zhonghu He Xueyong Zhang Chenyang Hao Jian Hou Aoyue Bi Xuebo Zhao Daxing Xu Botao Ye Xuchang Yu Ziying Wang Danni Liu Yuanfeng Hao Fei Lu Zifeng Guo | 2024 | The Crop Journal2024，12，1： | 0 |
