| 1 | Cr(VI) removal from aqueous solution with bamboo charcoal chemically modified by iron and cobalt with the assistance of microwave显示文摘Bamboo charcoal (BC) was used as starting material to prepare Co-Fe binary oxideloaded adsorbent (Co-Fe-MBC) through its impregnation in Co(NO3)2 , FeCl3 and HNO3 solutions simultaneously, followed by microwave heating. The low-cost composite was characterized and used as an adsorbent for Cr(VI) removal from water. The results showed that a cobalt and iron binary oxide (CoFe2O4 ) was uniformly formed on the BC through redox reactions. The composite exhibited higher surface area (331 m2/g) than that of BC or BC loaded with Fe alone (Fe-MBC). The adsorption of Cr(VI) strongly depended on solution pH, temperature and ionic strength. The adsorption isotherms followed the Langmuir isotherm model well, and the maximum adsorption capacities for Cr(VI) at 288 K and pH 5.0 were 35.7 and 51.7 mg/g for Fe-MBC and Co-Fe-MBC, respectively. The adsorption processes were well fitted by the pseudo second-order kinetic model. Thermodynamic parameters showed that the adsorption of Cr(VI) onto both adsorbents was feasible, spontaneous, and exothermic under the studied conditions. The spent Co-Fe-MBC could be readily regenerated for reuse. | Wei Wang Xuejiang Wang Xin Wang Lianzhen Yang Zhen Wu Siqing Xia Jianfu Zhao | 2013 | Journal of Environmental Sciences2013，25，9： | 14 |
| 2 | A MATHEMATICAL MODEL FOR RESERVOIR SEDIMENTATION AND FLUVIAL PROCESSES显示文摘This paper consists of two parts: mechanism of non-equilibrium transport of non-uniform sediment and its application in the mathematical model. Based on a statistic approach of sediment transport proposed by the authors, a 1 - D equation of non-e- quilibrium transport for various size group of sediment particles is developed. Then equations to predict change of sediment concentration and the corresponding changes in size distribution of suspended load and bed material are also derived. The conception that changes in size distribution are interrelated to sediment-carrying capacity is expounded. These results reveal the essence of sediment transport of non-uniform sediment particles. In the second part a mathematical model incorporating the mentioned equations to compute deposition and scouring in reservoirs as well as the fluvial processes of river channels has been developed. Verification of the model agrees well with field data. | Han Qiwei and He Mingmin (Senior Research Engineers, Dept. of Sedimentation Eng. Inst. of Water Conservancy and Hydroelectric Power Research.)

| 3 | RILL EROSION PROCESS ON STEEP SLOPE LAND OF THE LOESS PLATEAU显示文摘Rill erosion processes and principle of preventing rill erosion of different applied measures are studied by rainfall simulation and field investigation. Research results show that rill erosion processes can be schematically divided into five stages, that is, concentrated flow forming process; little waterfalls in the concentrated flow forming Process; little waterfalls developing into rill head cut process; rill head cuts developing to form discontinuous rill process and discontinuous rills connecting to form continuous rill process. Rill head cuts backward erosion, rill wall collapsing and runoff washing rill bed are the main patterns of rill development. The relevant equation between critical runoff volume of occurring rill erosion and slope degree can be expressed as follows: Q = 76. 10 - 2. 10J. And relevant equation between critical slope length of occurrence Of rill erosion and slope degree is parabolic with a minimum-value. In addition, influence of rill erosion development on slope runoff and soil erosion, benefits and principle of reducing rill erosion amount of mulch, non-tillage system and remained residue, strip alternation of grass and crop, horizontal ditch are also studied. | ZHENG Fenli and TANG Keli (1 The English text has been altered and edited by Dr. DING Lianzhen 2 Engineer, National Key Laboratory of Soil Erosion and Dryland Farming on Loess Plateau, Chinese Academy of Sciences and institute of Soil and Water Conservati | 1997 | International Journal of Sediment Research1997，12，1： | 9 |
| 4 | Hyperbolic Method to Analyze the Electrical Resistivity Curve of Portland Cements with Superplasticizer显示文摘Electrical measurement was employed to investigate the early hydration characteristics of cement pastes with different dosages of superplasticizer in the same W/C ratio.The hyperbolic method was applied to analyze the electrical resistivity development.The peak point(P_h)on the hyperbolic curve could be easily read.The time(th)to reach the point Ph had strong relations with the setting time.th was delayed with the increment of the dosage of superplasticizer.The time th was used to plot the relationship between the initial setting time and final setting time.The hyperbolic equation was established to predict the ultimate resistivity. The retardation effect of the superplasticizer was confirmed in the same W/C ratio by setting time and isothermal heat evolution. | WEI Xiaosheng XIAO Lianzhen LI Zongjin | 2008 | Journal of Wuhan University of Technology(Materials Science)2008，23，2： | 7 |

| 6 | Effect of Post-weld Heat Treatment on Properties of Friction Welded Joint Between TC4 Titanium Alloy and 40Cr Steel Rods显示文摘Dissimilar metal joining of Ti–6Al–4V(TC4) titanium alloy to as-rolled 40 Cr steel rods was conducted with friction welding, and the effect of post-weld heat treatment(PWHT) on the microstructure and mechanical properties of the resultant joints was investigated. The average tensile strength of the as-welded joints reached 766 MPa and failure occurred in 40 Cr steel base metal. However, after PWHT at 600 °C for 0.5, 1, 2 and 3 h, the tensile strength of the joints decreased and fracture happened through the interface with quasi-cleavage features. The bending angle of specimens was improved from 9.6° in as-welded state to 32.5° after PWHT for 2 h. The tensile strength of the joint was enhanced by martensitic transformation near the interface in as-welded state. Sorbite formed near the interface in PWHT state and improved the bending ductility of the joint. Ti C brittle phase formed at the interface after PWHT for 0.5 h and deteriorated the tensile strength and bending ductility of the joint. After PWHT for 2 h, no Ti C phase was detected at the interface. The microhardness on the interface in as-welded state was higher than that after PWHT, indicating that the decrease of microhardness around the interface could be accompanied by degradation of tensile strength but improvement of bending ductility of the joints. | Honggang Dong Lianzhen Yu Dewei Deng Wenlong Zhou Chuang Dong | 2015 | Journal of Materials Science & Technology2015，31，9： | 6 |
| 7 | Evaluation and scenario simulation for forest ecological security in China显示文摘Continuously growing populations and rapid economic development have led to the excessive use of forest resources,and the forest ecosystem is threatened.In response,forest ecological security(FES)has attracted attention.In this study,an integrated dynamic simulation model was constructed using the system dynamic method,and it was used to evaluate the FES in China from 1999 to 2014.A scenario analysis was then used to evaluate the changes in the FES under five forestry policy scenarios for the 2015–2050 period,including the baseline,afforestation policy,harvesting policies,management policy,investment policy,and a policy mix.The results showed that the evaluation values of the FES increased during the period from 1999 to 2002,the period from 2004 to 2010 and the year 2014,and they decreased in 2003 and during the period from 2011 to 2013.During the 2015–2050 simulation period,the FES improved continuously.In particular,China would enter a new stage when the economic systems,social systems and ecosystems were in harmony after 2040.To improve the FES and the current status of the FES,a scenario analysis showed the most suitable scenario to be Scenario 5 from 2015 to 2020 and Scenario 2 from 2021 to 2050.To relieve pressure,the most suitable scenario would be Scenario 5 from 2015 to 2040 and from 2046 to 2050,and the most suitable scenario would be Scenario 4 for 2041–2045.A policy mix(Scenario 5)would be most efficient under current conditions,while the effects of all the benefits of the forestry policies would weaken over the long term.The integrated method can be regarded as a decision support tool to help policy makers understand FES and promulgate a reasonable forestry policy. | Qin Zhang Guangyu Wang Feng Mi Xuanchang Zhang Lianzhen Xu Yufang Zhang Xiaoli Jiang | 2019 | Journal of Forestry Research2019，30，5： | 5 |
| 8 | Quantifying the adsorption and uptake of CuO nanoparticles by wheat root based on chemical extractions显示文摘Extensive application of metal nanoparticles is attracting more attention because of their potential environmental risks.Many studies have focused on the uptake of metal nanoparticles (NPs) by plant,but the adsorption of nanoparticles on root surface is often mistakenly regarded as their uptake.This study optimized the methods to distinguish the adsorption and uptake of CuO-NPs on the wheat root by applying different metal competing ions (Na +,Mg 2+,and La 3+ ),surfactant (i.e.,sodium dodecyl benzene sulfonate,SDBS),or complexing agents like NaOAc and Na 4 EDTA,as well as ultrasonic technique.The results indicated that some CuO-NPs is strongly adsorbed on the plant root surface,and part of them by mechanical adhesion.Competing ions could not desorb the CuO-NPs from the root surface,while NaOAc and Na 4 EDTA well dissolved the adsorbed CuO-NPs.In addition,the uptake and adsorption of CuO-NPs increased with increasing exposure concentrations of CuO-NPs in the range of 5-200 mg/L.The amount of CuO-NPs adsorption is always lower than that of their uptake. | Dongmei Zhou Shengyang Jin Lianzhen Li Yu Wang Nanyan Weng | 2011 | Journal of Environmental Sciences2011，23，11： | 3 |
| 9 | Artificial intelligence in gastric cancer:applications and challenges显示文摘Gastric cancer(GC)is one of the most common malignant tumors with high mortality.Accurate diagnosis and treatment decisions for GC rely heavily on human experts’careful judgments on medical images.However,the improvement of the accuracy is hindered by imaging conditions,limited experience,objective criteria,and inter-observer discrepancies.Recently,the developments of machine learning,especially deep-learning algorithms,have been facilitating computers to extract more information from data automatically.Researchers are exploring the far-reaching applications of artificial intelligence(AI)in various clinical practices,including GC.Herein,we aim to provide a broad framework to summarize current research on AI in GC.In the screening of GC,AI can identify precancerous diseases and assist in early cancer detection with endoscopic examination and pathological confirmation.In the diagnosis of GC,AI can support tumor-node-metastasis(TNM)staging and subtype classification.For treatment decisions,AI can help with surgical margin determination and prognosis prediction.Meanwhile,current approaches are challenged by data scarcity and poor interpretability.To tackle these problems,more regulated data,unified processing procedures,and advanced algorithms are urgently needed to build more accurate and robust AI models for GC. | Runnan Cao Lei Tang Mengjie Fang Lianzhen Zhong Siwen Wang Lixin Gong Jiazheng Li Di Dong Jie Tian | 2022 | Gastroenterology Report2022，10，1： | 3 |
| 10 | CT radiomics can help screen the coronavirus disease2019(COVID-19): a preliminary study显示文摘The coronavirus disease 2019(COVID-19) is raging across the world.The radiomics,which explores huge amounts of features from medical image for disease diagnosis,may help the screen of the COVID-19.In this study,we aim to develop a radiomic signature to screen COVID-19 from CT images.We retrospectively collect 75 pneumonia patients from Beijing Youan Hospital,including 46 patients with COVID-19 and 29 other types of pneumonias.These patients are divided into training set(n = 50) and test set(n = 25) at random.We segment the lung lesions from the CT images,and extract 77 radiomic features from the lesions.Then unsupervised consensus clustering and multiple cross-validation are utilized to select the key features that are associated with the COVID-19.In the experiments,while twenty-three radiomic features are found to be highly associated with COVID-19,four key features are screened and used as the inputs of support vector machine to build the radiomic signature.We use area under the receiver operating characteristic curve(AUC) and calibration curve to assess the performance of our model.It yields AUCs of 0.862 and 0.826 in the training set and the test set respectively.We also perform the stratified analysis and find that its predictive ability is not affected by gender,age,chronic disease and degree of severity.In conclusion,we investigate the value of radiomics in screening COVID-19,and the experimental results suggest the radiomic signature could be a potential tool for diagnosis of COVID-19. | Mengjie FANG Bingxi HE Li LI Di DONG Xin YANG Cong LI Lingwei MENG Lianzhen ZHONG Hailin LI Hongjun LI Jie TIAN | 2020 | Science China(Information Sciences)2020，63，7： | 2 |
