1Science and Prediction of Heavy Rainfall over China:Research Progress since the Reform and Opening-Up of New China显示文摘This paper reviews the major progress on development of the science and prediction of heavy rainfall over China since the beginning of the reform and opening-up of new China(roughly between 1980 and 2019).The progress of research on the physical mechanisms of heavy rainfall over China is summarized from three perspectives:1)the relevant synoptic weather systems,2)heavy rainfall in major sub-regions of China,and 3)heavy rainfall induced by typhoons.The development and application of forecasting techniques for heavy rainfall are summarized in terms of numerical weather prediction techniques and objective forecasting methods.Greatly aided by the rapid progress in meteorological observing technology and substantial improvement in electronic computing,studies of heavy rainfall in China have advanced to investigating the evolution of heavy-rain-producing storms and observational analysis of the cloud microphysical features.A deeper and more systematic understanding of the synoptic systems of importance to the production of heavy rainfall has also been developed.Operational forecast of heavy rainfall in China has changed from subjective weather event forecasts to a combination of both subjective and objective quantitative precipitation forecasts,and is now advancing toward probabilistic quantitative precipitation forecasts with the provision of forecast uncertainty information.Yali LUO Jisong SUN Ying LI Rudi XIA Yu DU Shuai YANG Yuanchun ZHANG Jing CHEN Kan DAI Xueshun SHEN Haoming CHEN Feifan ZHOU Yimin LIU Shenming FU Mengwen WU Tiangui XIAO Yangruixue CHEN Huiqi LI Mingxin LI 2020Journal of Meteorological Research2020,34,3:10
2CuS nanoplatelets arrays grown on graphene nanosheets as advanced electrode materials for supercapacitor applications显示文摘CuS nanoplatelets arrays grown on graphene nanosheets are successfully synthesized via a facile lowtemperature solvothermal reaction with graphene oxide(GO), CH_3 CSNH_2 and Cu(CH_3 COO)_2·H_2O as the reactants. CH_3CSNH_2 plays an important role in being the reducing agent for GO and the sulfur source of CuS. Supercapacitive performance of the graphene/CuS nanocomposite as active electrode materials has been evaluated by cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy measurements. The results indicate that graphene/CuS electrode delivers a high capacitance of 497.8 F g^(-1) at a current density of 0.2 A g^(-1), which outperforms bare CuS electrode. This excellent performance is ascribed to the short diffusion path and large surface area of the unique hierarchical nanostructure with nanoflakes building blocks for bulk accessibility of faradaic reaction.Xianfu Li Kaixuan Zhou Jianyu Zhou Jianfeng Shen Mingxin Ye 2018Journal of Materials Science & Technology2018,34,12:3
3Synthesis of a Novel Co-B/CTAB Catalyst via Solid-state-reaction at Room Temperature for Hydrolysis of Ammonia-borane显示文摘Cobalt-boride(Co-B)is emerging as one of the promising materials in the base-hydrolytic dehydrogena-tion of ammonia-borane(AB).In order to avoid the low specific area and poor catalytic capacity of Co-B catalyst caused by aggregation arising from the strong reducing property and rapid reaction condensation of sodium borohy-dride(NaBHa),novel cobalt boride/cetyltrimethylammonium bromide(Co-B/CTAB)catalyst was obtained via solid-state grinding at room temperature,and the catalyst was further characterized by XRD,SEM,XPS and BET.The hydrogen generation rate(HGR)was then determined by the hydrolysis reaction of AB.The SEM images indicate that a lot of irregular folds and curled edges are formed on the sample with a maximum surface area of 145.57 m2/g,thus possibly resulting in the high hydrogen production(HGR was 10.68 L.minlg),which may be attributed to CTAB that provide favorable large specific surface area and abundant porous structure.Additionally,catalyst will not be affected by solvants during solid-state reaction.As a diluent,the surfactant CTAB hindered the reaction rate of sodium borohydride reduction to cobalt boride and obtained the novel catalyst with a large specific surface area.HU Haibin LONG Bo JIANG Yifan SUN Shichang Ibrahim LAWAN ZHOU Weiming- ZHANG Mingxin WANG Liwei ZHANG Fan YUAN Zhanhui 2020Chemical Research in Chinese Universities2020,36,6:2

7Correlation between acne and Northwest dryness syndrome in Xinjiang autonomous region of China显示文摘OBJECTIVE: To analyze the correlation between acne and Northwest dryness syndrome in the Xinjiang region to provide an epidemiological foundation for the prevention and treatment of acne in the region. METHODS: The correlations among acne, clinical syndromes of Northwest dryness syndrome, and Northwest dryness syndrome were evaluated using the syndrome fitness index and canonical correlation analysis. RESULTS: The acne group had a Northwest dryness syndrome rate of 24.13%, and the control group 10.34%(χ2=7.733, P<0.01). There was no significant difference in the fitness index for acne and for the sub-syndromes of Northwest dryness syndrome(P> 0.05). The first canonical correlation coefficient was 0.5656(P<0.01). The acne-dependent variable group had the largest damp-heat syndrome load(0.8709), and the independent variable had the largest lung-heart-spleen pyretic dryness load(0.6766). CONCLUSION: Northwest dryness syndrome is a risk factor for acne in the Xinjiang region. Exogenous dryness and endogenous damp are frequently seen as subsyndromes in Northwest dryness syndrome in acne patients in the region. Acne was correlated with the damp-heat and lung-heart-spleen pyretic dryness sub-syndromes of Northwest dryness syndrome.Yan Wang Xiaozhong Wang Haiyan Yuan Jing Jing Huaike Chen Xiaohong Ren Lili Zhang Huitian Zhang Mingxin Zhou 2013Journal of Traditional Chinese Medicine2013,33,6:1

11Zinc-catecholete frameworks biomimetically grown on marine polysaccharide microfibers for soft electronic platform显示文摘Integrating functional nanomaterials on nonplanar organisms has emerged as a rising technology,while significant mismatch would cause interface failure and poor durability.Herein,we demonstrate a facile strategy to assemble crystalline catecholate frameworks with honeycomb lattice on seaweed-derived polysaccharide microfibers,which is expected to form biomimetic connections and maintain durable stability.By physiological coagulation,well-aligned ZnO nanoarrays are tightly attached on alginate fibers,which is fractionally adopted as sacrifice for heteroepitaxial growth of zinc-catecholate frameworks(Zn3(HHTP)2).Benefiting from amplification effect of in-situ formed heterojunctions,promoted interfacial charge transfer is achieved,which allows for fabricating broadband photodetectors.Combined with high porosity for gas adsorption,the heteroepitaxial catecholate framework further enables its use as highly selective ppb-level triethylamine sensors.This work provides a promising strategy for heteroepitaxial growth of catecholate frameworks on organo-substrates and opens new applications in wearable sensor platform based on comfortable biofibers.Kai Liu Mingxin Zhang Xinxin Du Anqin Zhou Bin Hui Yanzhi Xia Kewei Zhang 2023Nano Research2023,16,1:1

13Recent progress in electrospun nanofibers and their applications in heavy metal wastewater treatment显示文摘Novel adsorbents with a simple preparation process and large capacity for removing highly toxic and nondegradable heavy metals from water have drawn the attention of researchers.Electrospun nanofiber membranes usually have the advantages of large specific surface areas and high porosity and allowing flexible control and easy functionalization.These membranes show remarkable application potential in the field of heavy metal wastewater treatment.In this paper,the electrospinning technologies,process types,and the structures and types of nanofibers that can be prepared are reviewed,and the relationships among process,structure and properties are discussed.On one hand,based on the different components of electrospun nanofibers,the use of organic,inorganic and organic−inorganic nanofiber membrane adsorbents in heavy metal wastewater treatment are introduced,and their advantages and future development are summarized and prospected.On the other hand,based on the microstructure and overall structure of the nanofiber membrane,the recent progresses of electrospun functional membranes for heavy metal removal are reviewed,and the advantages of different structures for applications are concluded.Overall,this study lays the foundation for future research aiming to provide more novel structured adsorbents.Xizi Xu He Lv Mingxin Zhang Menglong Wang Yangjian Zhou Yanan Liu Deng-Guang Yu 2023Frontiers of Chemical Science and Engineering2023,17,3:1
14A neural network-based production process modeling and variable importance analysis approach in corn to sugar factory显示文摘Corn to sugar process has long faced the risks of high energy consumption and thin profits.However,it’s hard to upgrade or optimize the process based on mechanism unit operation models due to the high complexity of the related processes.Big data technology provides a promising solution as its ability to turn huge amounts of data into insights for operational decisions.In this paper,a neural network-based production process modeling and variable importance analysis approach is proposed for corn to sugar processes,which contains data preprocessing,dimensionality reduction,multilayer perceptron/convolutional neural network/recurrent neural network based modeling and extended weights connection method.In the established model,dextrose equivalent value is selected as the output,and 654 sites from the DCS system are selected as the inputs.LASSO analysis is first applied to reduce the data dimension to 155,then the inputs are dimensionalized to 50 by means of genetic algorithm optimization.Ultimately,variable importance analysis is carried out by the extended weight connection method,and 20 of the most important sites are selected for each neural network.The results indicate that the multilayer perceptron and recurrent neural network models have a relative error of less than 0.1%,which have a better prediction result than other models,and the 20 most important sites selected have better explicable performance.The major contributions derived from this work are of significant aid in process simulation model with high accuracy and process optimization based on the selected most important sites to maintain high quality and stable production for corn to sugar processes.Yi Tong Mou Shu Mingxin Li Yingwei Liu Ran Tao Congcong Zhou You Zhao Guoxing Zhao Yi Li Yachao Dong Lei Zhang Linlin Liu Jian Du 2023Frontiers of Chemical Science and Engineering2023,17,3:1

16Enhanced strength-ductility synergy via high dislocation density-induced strain hardening in nitrogen interstitial CrMnFeCoNi high-entropy alloy显示文摘The present work demonstrates that nitrogen doping inhibits the formation of deformation twins in a CrMnFeCoNi high entropy alloy,while significantly increases the strength without sacrificing much duc-tility at 77 K.Microstructural characterization and first-principles calculations were employed to unveil the role of interstitial nitrogen atoms in obtaining such an excellent combination of strength and ductility at 77 K.It is found that nitrogen addition increases generalized stacking fault energy(GSFE)and reduces twinning.However,the pinning of dislocations by nitrogen atoms effectively suppresses dislocation cross-slip and dynamic recovery and in turn,promotes the accumulation of dislocations.The high dislocation density induces a high strain hardening capacity and improves uniform elongation,which compensates for the ductility loss accompanied by solid solution strengthening.The effect of nitrogen doping enriches the design concept of high-and medium-entropy alloys,providing an economical and effective strategy to develop ultra-high-performance alloys that are suitable for cryogenic applications.Huabing Li Yu Han Hao Feng Gang Zhou Zhouhua Jiang Minghui Cai Yizhuang Li Mingxin Huang 2023Journal of Materials Science & Technology2023,,10:0
17Decentralized control design and implementation for magnetic levitation systems with extended state observer显示文摘This paper focuses on control design and synthesize for a class of magnetic levitation systems,which have a decentralized control for each suspension point.Due to the existence of mechanical coupling among four suspension points,large modeling uncertainties,unpredictable disturbances during the operation,and measurement noises,becomes challenging.To estimate and compensate for the effects of lumped uncertainties,this study employs the extended state observer(ESO)in conjunction with active disturbance rejection control(ADRC).Specifically,a novel ESO is proposed that utilizes output signals and their derivatives to estimate the lumped uncertainties more accurately,which simplifies the convergence proof conditions and has well engineering performance.This article is written in honor of B.M.Chen on the occasion of his 60th birthday.Specifically,this paper is inspired by his pioneering work on composite nonlinear feedback,which combines linear feedback and nonlinear compensator to enhance system performance Chen et al.(IEEE Trans Autom Control,40:427-439,2003).Qiang Chen Qing Yang Mingxin Liu Peichang Yu Lianchun Wang Danfeng Zhou Jie Li Ying Tan 2023Control Theory and Technology2023,21,3:0
18Variations in the natural 13C and 15N abundance of plants and soils under long-term N addition and precipitation reduction:interpretation of C and N dynamics显示文摘Background:The nitrogen isotope natural abundance(δ^(15)N)provides integrated information on ecosystem N dynamics,and carbon isotope natural abundance(δ^(13)C)has been used to infer how water-using processes of plants change in terrestrial ecosystems.However,howδ^(13)C andδ^(15)N abundances in plant life and soils respond to N addition and water availability change is still unclear.Thus,δ^(13)C andδ^(15)N abundances in plant life and soils were used to investigate the effects of long-time(10 years)N addition(+50 kg N·ha^(−1)·yr^(−1)and precipitation reduction(−30%of throughfall)in forest C and N cycling traits in a temperate forest in northern China.Results:We analyzed theδ^(13)C andδ^(15)N values of dominant plant foliage,litterfall,fungal sporophores,roots,and soils in the study.The results showed thatδ^(15)N values of foliage,litterfall,and surface soil layer’s(0–10 cm)total N were significantly increased by N addition,whileδ^(15)N values of fine roots and coarse roots were considerably decreased.Nitrogen addition also significantly increased theδ^(13)C value of fine roots and total N concentration of the surface soil layer compared with the control.The C concentration,δ^(13)C,andδ^(15)N values of foliage andδ^(15)N values of fine roots were significantly increased by precipitation reduction,while N concentration of foliage and litterfall significantly decreased.The combined effects of N addition and precipitation reduction significantly increased theδ^(13)C andδ^(15)N values of foliage as well as theδ^(15)N values of fine roots andδ^(13)C values of litterfall.Furthermore,foliarδ^(15)N values were significantly correlated with foliageδ^(13)C values,surface soilδ^(15)N values,surface soil C concentration,and N concentrations.Nitrogen concentrations andδ^(13)C values of foliage were significantly correlated withδ^(15)N values and N concentrations of fine roots.Conclusions:This indicates that plants increasingly take up the heavier 15N under N addition and the heavier 13C and 15N under precipitation reduction,suggesting that N addition and precipitation reduction may lead to more open forest ecosystem C and N cycling and affect plant nutrient acquisition strategies.Guoyong Yan Shijie Han Mingxin Zhou Wenjing Sun Binbin Huang Honglin Wang Yajuan Xing Qinggui Wang 2020Forest Ecosystems2020,7,4:0
19Current status of municipal wastewater treatment plants in North-east China:implications for reforming and upgrading显示文摘Climate affects the natural landscape,the economic productivity of societies,and the lifestyles of its inhabitants.It also influences municipal wastewater treatment.Biological processes are widely employed in municipal wastewater treatment plants(WWTPs),and the prolonged cold conditions brought by the winter months each year pose obstacles to meeting the national standards in relatively cold regions.Therefore,both a systematic analysis of existing technical bottlenecks as well as promising novel technologies are urgently needed for these cold regions.Taking North-east China as a case,this review studied and analyzed the main challenges affecting 20 municipal WWTPs.Moreover,we outlined the currently employed strategies and research issues pertaining to low temperature conditions.Low temperatures have been found to reduce the metabolism of microbes by 58%or more,thereby leading to chemical oxygen demand(COD)and NH_(4)^(-)-N levels that have frequently exceeded the national standard during the winter months.Furthermore,the extracellular matrix tends to lead to activated sludge bulking issues.Widely employed strategies to combat these issues include increasing the aeration intensity,reflux volume,and flocculant addition;however,these strategies increase electricity consumption by>42%in the winter months.Internationally,the processes of anaerobic ammonium oxidation(anammox),granular sludge,and aerobic denitrification have become the focus of research for overcoming low temperature.These have inspired us to review and propose directions for the further development of novel technologies suitable for cold regions,thereby overcoming the issues inherent in traditional processes that have failed to meet the presently reformed WWTP requirements.Bin Cui Chongjun Zhang Liang Fu Dandan Zhou Mingxin Huo 2023Frontiers of Environmental Science & Engineering2023,17,6:0
20A novel photonic crystal vertical cavity surface emitting laser based on coherent coupling显示文摘We demonstrate a novel oxide confined GaAs-based photonic crystal vertical cavity surface emitting laser (PC-VCSEL) operating at a wavelength of 850 nm based on coherent coupling. A ring-shaped light-emitting aperture is added to the conventional PC-VCSEL, and coherent coupling is achieved between the central defect aperture and the ring-shaped light-emitting aperture. Measurements show that under the continuous-wave (CW) injected current of 20 mA, a high power of 2 mW is obtained, and the side mode suppression ratio (SMSR) is larger than 20 dB. The average divergence angle is 4.2° at the current level of 20 mA. Compared with the results ever reported, the divergence angle is reduced.LIU AnJin QU HongWei XING MingXin CHEN Wei ZHOU WenJun ZHENG WanHua 2010Chinese Science Bulletin2010,55,2:0
