| 1 | Predicting Cadmium Safety Thresholds in Soils Based on Cadmium Uptake by Chinese Cabbage显示文摘Cadmium(Cd), a common toxic heavy metal in soil, has relatively high bioavailability, which seriously threatens agricultural products. In this study, 8 different soils with contrasting soil properties were collected from different regions in China to investigate the Cd transfer coefficient from soil to Chinese cabbage(Brassica chinensis L.) and the threshold levels of Cd in soils for production of Chinese cabbage according to the food safety standard for Cd. Exogenous Cd(0–4 mg kg^(-1)) was added to the soils and equilibrated for 2 weeks before Chinese cabbage was grown under greenhouse conditions. The influence of soil properties on the relationship between soil and cabbage Cd concentrations was investigated. The results showed that Cd concentration in the edible part of Chinese cabbage increased linearly with soil Cd concentration in 5 soils, but showed a curvilinear pattern with a plateau at the highest dose of exogenous Cd in the other 3 soils. The Cd transfer coefficient from soil to plant varied significantly among the different soils and decreased with increasing soil p H from 4.7 to 7.5. However, further increase in soil pH to > 8.0 resulted in a significant decrease in the Cd transfer coefficient. According to the measured Cd transfer coefficient and by reference to the National Food Safety Standards of China, the safety threshold of Cd concentration in soil was predicted to be between 0.12 and 1.7 mg kg^(-1) for the tested soils. The predicted threshold values were higher than the current soil quality standard for Cd in 5 soils, but lower than the standard in the other 3 soils. Regression analysis showed a significant positive relationship between the predicted soil Cd safety threshold value and soil p H in combination with soil organic matter or clay content. | LU Junhe YANG Xinping MENG Xuchao WANG Guoqing LIN Yusuo WANG Yujun ZHAO Fangjie | 2017 | Pedosphere2017，27，3： | 13 |
| 2 | Characterization of the start-up behavior and steady-state performance of biotrickling filter removing low concentration toluene waste gas显示文摘A biotrickling filter packed with the regular ceramic spheres was designed and fabricated to purify the low toluene-concentration waste gas.Particular attention was made to the study of the start-up behavior of the biotrickling filter.Moreover,the steady performances were investigated to establish the experimental correlation between the operation factors and removal efficiency.It was found that the start-up process of the biotrickling filter exhibited three stages including the biofilm formation,biofilm development,and biofilm stabilization.The OD600 nm of the circulated liquid,gas pressure drop,elimination capacity,and temperature rise maintained at a rather low level in the biofilm formation stage,then increased rapidly in the biofilm development stage,and finally reached a stable value in the biofilm stabilization stage.It was also found that the removal efficiency of the biotrickling filter in the stable period decreased with increase in the waste gas flow rate,circulated liquid flow rate,and diameter of the ceramic sphere.More interestingly,it was revealed the operation modes have a significant influence on the removal efficiency of the biotrickling filter,and the microorganism show a high activity under the operating temperature ranging from 30°C to 40°C.The experimental correlations for describing the effect of operation factors on the removal efficiency of the biotrickling filters under both the co-current and counter-current operation modes were obtained.The correlation results are in good agreement with the experimental data. | CHEN Rong LIAO Qiang TIAN Xin WANG YongZhong ZHU Xun MIAO JunHe | 2012 | Science China(Technological Sciences)2012，55，6： | 4 |
| 3 | Thermally stable photoluminescence and long persistent luminescence of Ca3Ga4O9:Tb^3+/Zn^2+显示文摘A green long persistent luminescence(LPL) phosphor Ca_3 Ga_4 O_9:Tb^(3+)/Zn^(2+) was prepared. Ca_3 Ga_4 O_9 matrix exhibits blue self-activated LPL due to the creation of intrinsic traps. When Tb3+ is doped, the photoluminescence(PL) and LPL colors change from blue to green with their intensities significantly enhanced. The doping of Zn^(2+) evidently improves the PL and LPL performances of the Ca_3Ga_4O_9 matrix and Ca_3Ga_4O_9:Tb^(3+). The thermoluminescence(TL) spectra show that a successive trap distribution is formed by multiple intrinsic traps with different depths in the Ca_3 Ga_4 O_9 matrix, and the incorporation of Tb^(3+) and Zn^(2+) effectively increases the densities of these intrinsic traps. The existence of a successive trap distribution makes the Ca_3 Ga_4 O_9:Tb^(3+)/Zn^(2+) phosphor exhibit thermally stable PL and LPL, It is indicated that this phosphor shows great promise for the application such as high-temperature LPL phosphor. | Zhangwen Long Junhe Zhou Jianbei Qiu Qi Wang Dacheng Zhou Xuhui Xu Xue Yu Hao Wu Zhencai Li | 2018 | Journal of Rare Earths2018，36，7： | 4 |
| 4 | Electrolyte/Electrode Interfaces in All‑Solid‑State Lithium Batteries:A Review显示文摘All-solid-state lithium batteries are promising next-generation energy storage devices that have gained increasing attention in the past decades due to their huge potential towards higher energy density and safety.As a key component,solid electrolytes have also attracted significant attention and have experienced major breakthroughs,especially in terms of Li-ion conductivity.However,the poor electrode compatibility of solid electrolytes can lead to the degradation of electrolyte/electrode interfaces,which is the major cause for failure in all-solid-state lithium batteries.To address this,this review will summarize the indepth understanding of physical and chemical interactions between electrolytes and electrodes with a focus on the contact,charge transfer and Li dendrite formation occurring at electrolyte/electrode interfaces.Based on mechanistic analyses,this review will also briefly present corresponding strategies to enhance electrolyte/electrode interfaces through compositional modifications and structural designs.Overall,the comprehensive insights into electrolyte/electrode interfaces provided by this review can guide the future investigation of all-solid-state lithium batteries. | Yuepeng Pang Jinyu Pan Junhe Yang Shiyou Zheng Chunsheng Wang | 2021 | Electrochemical Energy Reviews2021，4，2： | 3 |
| 5 | Engineering CoMoO_(4) in reduced graphene oxide as superior cathode hosts for advanced room-temperature sodium-sulfur batteries显示文摘Promising room-temperature sodium-sulfur(RT Na-S)battery systems rely on purposely designed highperforming and low-cost electrode materials.Nevertheless,there are the challenges of irreversible dissolution and slow redox kinetics of NaPSs in the complete discharge of sulfur capacity.Herein,engineered CoMoO_(4)in reduced graphene oxide(CoMoO_(4)@rGO)is reported as a class of superior cathode hosts for RT Na-S batteries.The CoMoO_(4)@rGO matrix is designed to facilitate the reversible sodiation and desodiation of sulfur,considering the strong chemisorption between sulfur(and short-chain sodium sulfides)and CoMoO_(4),which alleviates the shuttle effect of sodium sulfides and accelerates the electrochemical reaction rate at RT.The obtained S/CoMoO_(4)@rGO cathode with~52%S loading exhibits a high capacity of520.1 mA h g^(-1)after 100 cycles at 0.1 A g^(-1).Moreover,an enhanced long-term performance at high current densities(212.2 mA h g^(-1)at 4 A g^(-1)over 1000 cycles)with high Coulombic efficiency(~100%)is also achieved.This work demonstrates a novel multifunctional additive for RT Na-S battery cathodes,which is expected to promote the long-waited development towards practical applications of RT Na-S batteries. | Xin Ye Sainan Luo Zhiqi Li Jiafeng Ruan Yuepeng Pang Junhe Yang John Wang Shiyou Zheng | 2023 | Journal of Energy Chemistry2023，，11： | 1 |

| 9 | Tunable light emission from carbon dots by controlling surface defects显示文摘Carbon dots(CDs)are metal-free fluorescent materials that can be used in optical and electronic devices,but few studies have focused on one-step synthesis routes for CDs with tunable color and high photoluminescence quantum yield(PLQY).Herein,CDs with tunable light emission were synthesized using a novel amide-assisted solvothermal approach.The as-prepared CDs were well dispersed and homogeneous,with average diameters of approximately 2.0–4.0 nm,depending on the dopants.Owing to the surface states with different ratios of nitrogen-and oxygen-related species,different CDs can exhibit blue,green,red,or white emission with relatively high PLQYs of 61.6%,41.3%,29.1%and 19.7%,respectively.XPS measurements,in conjunction with DFT calculations,indicate that nitrogen substitution(pyridinic/pyrrolic nitrogen)dominates the blue emission,while introducing oxygen functional groups lowered the LUMO energy level,which resulted in redder emission.In addition,the CDs are demonstrated as a bioimaging probe in both in vitro and in vivo assays,and the white light CDs have been demonstrated to be potential fluorescent materials for white-light-emitting diode(WLED). | Huijun Li Sancan Han Bowen Lyu Ting Hong Shibo Zhi Ling Xu Fengfeng Xue Liman Sai Junhe Yang Xianying Wang Bin He | 2021 | Chinese Chemical Letters2021，32，9： | 1 |
| 10 | NATURAL HISTORY OBSERVATION FOR ESOPHAGEAL AND CARDIA PRECURSORS BY REPETITIVE ENDOSCOPIC SCREENING OF 301 SUBJECTS IN SHEXIAN显示文摘OBJECTIVE To investigate the natural history of fast developing esopha- geal and cardia precursors. METHODS Repetitive endoscopic screenings were performed among 40-69-year-olds in the high-incidence areas for esophageal cancer in Shexian. RESULTS The initial diagnosis and the lag-time for 7 subsequently identified severe dysplasia(SD)subjects were as follows:in one subject 13 months after a baseline diagnosis of normal epithelium,in another subject 7 months after a baseline diagnosis of base cell hyperplasia(BCH),in four subjects 3,4,4,and 10.5 months after baseline diagnosis of mild dysplasia (mD),and in one subject 12.5 months after a baseline diagnosis of moder- ate dysplasia(MD).The initial diagnosis and the lag-time for 6 subsequently identified carcinomas in situ or intramucosal carcinoma cases were:in one case 48 months after a baseline diagnosis of mD,in 2 cases 4 and 13 months after baseline diagnoses of MD,and in the other 3 cases 3.5,9,and 17.5 months after baseline diagnoses of SD.The initial diagnosis and lag- time for 3 subsequently identified invasive cancer cases were:in one case 50 months after a baseline diagnosis of MD,in 2 cases 14 and 19 months after baseline diagnoses of SD.In addition,during a 4-year-fol ow-up of 18 subjects after endoscopic mucosa resection,9 of them were found to have developed precursors again at other sites,and also additional findings were obtained for 11 of the 16 dysplasia cases by repetitive biopsy in less than 2 months after the initial endoscopy. CONCLUSION A 5-year screening interval for BCH and mD,and a 3-year interval for MD may be too long for the fast developing precursors.Periodic screenings with shorter intervals should be considered to control the number of interval cases due to fast development,multifocal carcinogenesis,and false negative results inherent in one-time endoscopic biopsy sampling. | Denggui Wen Shijie Wang Liwei Zhang Yingsai Li Weifang Yu Xiaoling Wang Junhe Wang Suping Li Yongwei Li Shunping Wang Limian Er Caifen Ma | 2007 | Chinese Journal of Clinical Oncology2007，4，2： | 1 |
| 11 | A NIR to NIR rechargeable long persistent luminescence phosphor Ca_(2)Ga_(2)GeO_(7):Yb^(3+),Tb^(3+)显示文摘Near infrared to near infrared(NIR-NIR)photo-stimulated persistent luminescence(PSPL)has shown excellent potential in high-resolution bioimaging for deep tissues.However,the PSPL in NIR-Ⅱregion(900-1700 nm)is still lacking.In this work,Ca_(2)Ga_(2)GeO_(7):Yb^(3+),Tb^(3+)(CGGYT)phosphor with unique lowdimensional crystal structure was synthesized by high-temperature solid-state reaction.Thanks to the carriers transferring from deep traps to shallow ones induced by low energy light,the 978 nm PSPL originating from ^(2)F_(5/2) to ^(2)F_(7/2) transition of Yb^(3+)induced by multimode stimulating(980 nm or WLED)is successfully realized after pre-excited by UV lamp.The NIR PSPL of the specimen can be repeatedly stimulated after placed in dark for 12 h.Moreover,the results indicate that codoping with Tb^(3+)can significantly enhance the NIR-ⅡPSPL owing to the quantum cutting persistent energy transfer(QC PET)from Tb^(3+)to Yb^(3+).Our study points to a new direction for the future development of multimode PSPL materials for bioimaging or multimode optical storage applications. | Junhe Zhou Zhangwen Long Jianbei Qiu Dacheng Zhou Jun'an Lai Xuhui Xu Songhan Hu Xizheng Li Qi Wang | 2021 | Journal of Rare Earths2021，39，12： | 1 |

| 13 | Combining field data and modeling to better understand maize growth response to phosphorus(P) fertilizer application and soil P dynamics in calcareous soils显示文摘We used field experimental data to evaluate the ability of the agricultural production system model (APSIM) to simulate soil P availability,maize biomass and grain yield in response to P fertilizer applications on a fluvo-aquic soil in the North China Plain.Crop and soil data from a 2-year experiment with three P fertilizer application rates(0,75 and 300 kg P_(2)O_(5) ha^(–1)) were used to calibrate the model.Sensitivity analysis was carried out to investigate the influence of APSIM SoilP parameters on the simulated P availability in soil and maize growth.Crop and soil P parameters were then derived by matching or relating the simulation results to observed crop biomass,yield,P uptake and Olsen-P in soil.The re-parameterized model was further validated against 2 years of independent data at the same sites.The re-parameterized model enabled good simulation of the maize leaf area index (LAI),biomass,grain yield,P uptake,and grain P content in response to different levels of P additions against both the calibration and validation datasets.Our results showed that APSIM needs to be re-parameterized for simulation of maize LAI dynamics through modification of leaf size curve and a reduction in the rate of leaf senescence for modern staygreen maize cultivars in China.The P concentration limits (maximum and minimum P concentrations in organs)at different stages also need to be adjusted.Our results further showed a curvilinear relationship between the measured Olsen-P concentration and simulated labile P content,which could facilitate the initialization of APSIM P pools in the NCP with Olsen-P measurements in future studies.It remains difficult to parameterize the APSIM SoilP module due to the conceptual nature of the pools and simplified conceptualization of key P transformation processes.A fundamental understanding still needs to be developed for modelling and predicting the fate of applied P fertilizers in soils with contrasting physical and chemical characteristics. | Weina Zhang Zhigan Zhao Di He Junhe Liu Haigang Li Enli Wang | 2024 | Journal of Integrative Agriculture2024，23，3： | 0 |
| 14 | Dynamics and controls of ecosystem multiserviceability across the Qingzang Plateau显示文摘Ecosystem multiserviceability(EMS),a comprehensive and significant ecological indicator,reflects the capacity of ecosystems to offer multiple services concurrently.Intensified climate change and human activity are continu-ously altering ecosystem functions,services,and EMSs.However,numerous studies have only focused on one or a few ecosystem services,rarely taking into account spatial-temporal distribution and drivers of EMS on behalf of different agencies.We calculated EMS including pastoralist(PA),environmental protection agency(EPA),bio-diversity conservation agency(BCA),and climate change mitigation agency(CCMA)using grassland production,habitat quality,water conservation,and carbon sequestration.Then,the effects of geographical features,climate factors,and human activities on spatial-temporal patterns of EMS were explored.The result indicated that EMS showed a decreasing tendency from the southeast to northwest on the Qingzang Plateau(QZP).Meanwhile,there were no obvious fluctuations in four simulated scenarios(PA,EPA,BCA and CCMA)among different vegetation types during 2000 to 2015.Notably,EMS of all simulated scenarios decreased in the alpine steppe ecosystem,but negligible changes were found in other ecosystems from 2015 to 2020.Moreover,the relative importance of precipitation in annual mean value(from 2000 to 2020)of PA,EPA,BCA and CCMA were 0.13,0.11,0.30 and 0.19,respectively.Overall,precipitation played the dominant role on the dynamics of EMS,followed by elevation and human footprint.Our findings highlighted that understanding the patterns and drivers of EMS could provide a reference for the regional management and maintenance of ecosystem stability on QZP. | Ruowei Li Guodong Han Jian Sun Tiancai Zhou Junhe Chen Wen He Yi Wang | 2023 | Geography and Sustainability2023，4，4： | 0 |
| 15 | Preparation and formaldehyde sensitive properties of N-GQDs/SnO2 nanocomposite显示文摘Graphene quantum dots(GQDs)have both the properties of graphene and semiconductor quantum dots,and exhibit stronger quantum confinement effect and boundary effect than graphene.In addition,the band gap of GQDs will transform to non-zero from 0 eV of graphene by surface functionalization,which can be dispersed in common solvents and compounded with solid materials.In this work,the SnO2 nanosheets were prepared by hydrothermal method.As the sensitizer,nitrogen-doped graphene quantum dots(N-GQDs)were prepared and composited with SnO2 nanosheets.Sensing performance of pristine SnO2 and N-GQDs/SnO2 were investigated with HCHO as the target gas.The response(Ra/Rg)of0.1%N-GQDs/SnO2 was 256 for 100 ppm HCHO at 60℃,which was about 2.2 times higher than pristine SnO2 nanosheet.In addition,the material also had excellent selectivity and low operation temperature.The high sensitivity of N-GQDs/SnO2 was attributed to the increase of active sites on materials surface and the electrical regulation of N-GQDs.This research is helpful to develop new HCHO gas sensor and expand the application field of GQDs. | Zhenlu Chen Ding Wang Xianying Wang Junhe Yang | 2020 | Chinese Chemical Letters2020，31，8： | 0 |
| 16 | Configurations of Shock Regular Reflection by Straight Wedges显示文摘We are concerned with the shock regular reflection configurations of unsteady global solutions for a plane shock hitting a symmetric straight wedge.It has been known that patterns of the shock reflection are various and complicated,including the regular and the Mach reflection.Most of the fundamental issues for the shock reflection have not been understood.Recently,there are great progress on the mathematical theory of the shock regular reflection problem,especially for the global existence,uniqueness,and structural stability of solutions.In this paper,we show that there are two more possible configurations of the shock regular reflection besides known four configurations.We also give a brief proof of the global existence of solutions. | Qin Wang Junhe Zhou | 2023 | Communications on Applied Mathematics and Computation2023，5，3： | 0 |
| 17 | Fabrication of Cu/graphite film/Cu sandwich composites with ultrahigh thermal conductivity for thermal management applications显示文摘Effective thermal management of electronic integrated devices with high powder density has become a serious issue,which requires materials with high thermal conductivity(TC).In order to solve the problem of weak bonding between graphite and Cu,a novel Cu/graphite film/Cu sandwich composite(Cu/GF/Cu composite)with ultrahigh TC was fabricated by electro-deposition.The micro-riveting structure was introduced to enhance the bonding strength between graphite film and deposited Cu layers by preparing a rectangular array of micro-holes on the graphite film before electrodeposition.TC and mechanical properties of the composites with different graphite volume fractions and current densities were investigated.The results showed that the TC enhancement generated by the micro-riveting structure for Cu/GF/Cu composites at low graphite content was more effective than that at high graphite content,and the strong texture orientation of deposited Cu resulted in high TC.Under the optimizing preparing condition,the highest in-plane TC reached 824.3 W·m^-1·K^-1,while the ultimate tensile strength of this composite was about four times higher than that of the graphite film. | Rui ZHAO Weikai L Tian WANG Ke ZHAN Zheng YANG Ya YAN Bin ZHAO Junhe YANG | 2020 | Frontiers of Materials Science2020，14，2： | 0 |
| 18 | A multiple-pattern complex event matching model based on merge sharing for massive event streams显示文摘Quickly matching the related primitive events for multiple complex events from the massive event streams usually faces with a great challenge due to the single-pattern characteristics of the existing complex event matching models. Aiming to solve the problem, amultiple-pattern complex event matching model based on merge sharing is proposed inthis paper. The achievement of the paper lies in the fact that a multiple-pattern complexevent matching model based on merge sharing is presented to successfully realize thequick matching of related primitive events for multiple complex events from the massiveevent streams. Specifically, in our scheme, we successfully use merge sharing technologyto merge all the same prefixes, suffixes or subpatterns existing in single-pattern matchingmodels into shared ones and to construct a multiple-pattern complex event matchingmodel. As a result, our proposed matching model in this paper can effectively solve theabove problem. The experimental results show that our proposed matching model in thispaper outperforms the existing single-pattern matching models in model constructionand related events matching for massive event streams. | Jianhua Wang Junhe Liu Feng Lin Jing Zhao Yongbing Long Yubin Lan | 2021 | International Journal of Modeling, Simulation, and Scientific Computing2021，12，4： | 0 |
