1A New Critical Nitrogen Dilution Curve for Rice Nitrogen Status Diagnosis in Northeast China显示文摘In-season diagnosis of crop nitrogen(N) status is crucial for precision N management. Critical N(N_c) dilution curve and N nutrition index(NNI) have been proposed as effective methods to diagnose N status of different crops. The N_c dilution curves have been developed for indica rice in the tropical and temperate zones and japonica rice in the subtropical-temperate zone, but they have not been evaluated for short-season japonica rice in Northeast China. The objectives of this study were to evaluate the previously developed N_c dilution curves for rice in Northeast China and to develop a more suitable N_c dilution curve in this region. A total of17 N rate experiments were conducted in Sanjiang Plain, Heilongjiang Province in Northeast China from 2008 to 2013. The results indicated that none of the two previously developed N_c dilution curves was suitable to diagnose N status of the short-season japonica rice in Northeast China. A new N_c dilution curve was developed and can be described by the equation N_c = 27.7 W^(-0.34) if W ≥ 1 Mg dry matter(DM) ha^(-1) or N_c = 27.7 g kg^(-1) DM if W < 1 Mg DM ha^(-1), where W is the aboveground biomass. This new curve was lower than the previous curves. It was validated using a separate dataset, and it could discriminate non-N-limiting and N-limiting nutritional conditions. Additional studies are needed to further evaluate it for diagnosing N status of different rice cultivars in Northeast China and develop efficient non-destructive methods to estimate NNI for practical applications.HUANG Shanyu MIAO Yuxin CAO Qiang YAO Yinkun ZHAO Guangming YU Weifeng SHEN Jianning YU Kang Georg BARETH 2018Pedosphere2018,28,5:10

7Geochemistry of ore-forming fluids and geological significance of the Kuoerzhenkuola gold field in Xinjiang, China显示文摘The Kuoerzhenkuola gold field (including the Kuoerzhenkuola and the Buerkesidai gold deposits) is the most important one in the Sawuer gold belt, northern Xinjiang, China. Iso-topic studies including D, O, He, C, S, Pb and Sr reveal that the ore-forming fluids of the Kuo-erzhenkuola and the Buerkesidai deposits shared the same source: the water of ore fluids was magmatic water and minor meteoric water; the mineralizers and ore materials derived mainly from mantle beneath the island arc, and partially from crust. The ore-forming fluids of two depos-its are a mixture of mantle-derived fluids incorporated by crust-derived fluid, and meteoric water. Based on these results, combined with the consideration of the tectonic setting and geological features, we suggest that the two gold deposits in the Kuoerzhenkuola gold field, Sawur gold belt share the same genesis, and are volcanogenic hydrothermal gold deposits occurring in the same caldera.SHEN Ping SHEN Yuanchao LIU Tiebing LI Guangming ZENG Qingdong 2005Science China Earth Sciences2005,48,11:3
8Photodegradation of amoxicillin by catalyzed Fe^(3+)/H_2O_2 process显示文摘Three oxidation processes of UV-Fe3+(EDTA)/H2O2(UV:ultraviolet light;EDTA:ethylenediaminetetraacetic acid),UV-Fe3+/H2O2 and Fe3+/H2O2 were simultaneously investigated for the degradation of amoxicillin at pH 7.0.The results indicated that,100% amoxicillin degradation and 81.9% chemical oxygen demand(CODCr) removal could be achieved in the UV-Fe3+(EDTA)/H2O2 process.The treatment efficiency of amoxicillin and CODCr removal were found to decrease to 59.0% and 43.0% in the UV-Fe3+/H2O2 process;39.6% and 31.3% in the Fe3+/H2O2 process.Moreover,the results of biodegradability(biological oxygen demand(BOD5)/CODCr ratio) revealed that the UV-Fe3+(EDTA)/H2O2 process was a promising strategy to degrade amoxicillin as the biodegradability of the effuent was improved to 0.45,compared with the cases of UV-Fe3+/H2O2(0.25) and Fe3+/H2O2(0.10) processes.Therefore,it could be deduced that EDTA and UV light performed synergetic catalytic effect on the Fe3+/H2O2 process,enhancing the treatment efficiency.The degradation mechanisms were also investigated via UV-Vis spectra,and high performance liquid chromatography-mass spectra.The degradation pathway of amoxicillin was further proposed.Xiaoming Li Tingting Shen Dongbo Wang Xiu Yue Xian Liu Qi Yang Jianbin Cao Wei Zheng Guangming Zeng 2012Journal of Environmental Sciences2012,24,2:3
9A high quality image reconstruction method based on nonconvex decoding显示文摘The article proposes a fast reconstruction algorithm for l0≤p≤1 norm nonconvex model,called Gradient projection nonconvex sparse recovery(GPNSR),which makes a good performance in high-quality image reconstruction.We apply the GPNSR into canonical multiple description coding theory and propose a robust high-quality compressed sensing-based coding method.Combined with iterative weighted technique and fast gradient descent method,the proposed method implicitly implements matrix inverse operations to highly reduce the storage pressure.Also the weighted norm method is taken to optimize the descent steps,which highly increases convergent speed of the algorithm.Taking an image has sparse Fourier representations as an example,the paper presents the detailed image sparse coding and fast reconstruction procedure.By integrating the compressive sensing multi-description coding framework,the simulation demonstrates the superior reconstruction performance of the proposed algorithm.Most importantly,with p close to zero,the reconstruction performance of GPNSR can approximate that of l0 norm optimization result.ZHAO GuangHui SHEN FangFang WANG ZhengYang WU WeiJia SHI GuangMing LIU DanHua 2013Science China(Information Sciences)2013,56,11:3

17Synthesis,structure and catalytic activity of complexes [Ln(EDBP)_2(DME)Na(DME)_3](Ln=Er,Yb,Sm) for ring-opening polymerization of ε-caprolactone显示文摘Discrete ion-pair complexes [Ln(EDBP)2(DME)Na(DME)3] [Ln=Er (1), Yb (2), Sm (3)] have been synthesized by the reaction between sodium salt of 2,2'-ethylidene-bis(4,6-di-tert-butylphenol)(EDBPH2) and Ln(BH4)3·3THF (Ln=Er, Yb, Sm) followed by centrifugation and recrystalization. The complexes were characterized by elemental analysis and FT-IR, and the bonding model of these compounds was confirmed by X-ray single crystal diffraction for complex 1. It was found that four O atoms in two biphenol ligands as well as two O atoms in one ethylene glycol dimethyl ether (DME) molecule connect to the center rare earth metal atom, while sodium exists as counterpart cation to balance the charge. Complexes 1―3 can all be used as single component initiators for the ring-opening polymerization of ε-caprolactone.YU JianFang, WU GuangMing, HUANG Jing, SUN WeiLin & SHEN ZhiQuan Key Laboratory of Macromolecular Synthesis and Functionalization, Ministry of Education, Department of Polymer Science and Engineering, Zhejiang University, Hangzhou 310027, China 2009Science China Chemistry2009,52,10:1

19Electrochemical removal of ammonium nitrogen in high efficiency and N_(2) selectivity using non-noble single-atomic iron catalyst显示文摘Ammonia nitrogen (NH_(4)^(+)-N) is a ubiquitous environmental pollutant,especially in offshore aquaculture systems.Electrochemical oxidation is very promising to remove NH_(4)^(+)-N,but suffers from the use of precious metals anodes.In this work,a robust and cheap electrocatalyst,iron single-atoms distributed in nitrogen-doped carbon (Fe-SAs/N-C),was developed for electrochemical removal of NH_(4)^(+)-N from in wastewater containing chloride.The FeSAs/N-C catalyst exhibited superior activity than that of iron nanoparticles loaded carbon(Fe-NPs/N-C),unmodified carbon and conventional Ti/IrO_(2)-TiO_(2)-RuO_(2)electrodes.And high removal efficiency (>99%) could be achieved as well as high N_(2)selectivity (99.5%) at low current density.Further experiments and density functional theory (DFT) calculations demonstrated the indispensable role of single-atom iron in the promoted generation of chloride derived species for efficient removal of NH_(4)^(+)-N.This study provides promising inexpensive catalysts for NH_(4)^(+)-N removal in aquaculture wastewater.Fengjiao Quan Guangming Zhan Bing Zhou Cancan Ling Xiaobing Wang Wenjuan Shen Jianfen Li Falong Jia Lizhi Zhang 2023Journal of Environmental Sciences2023,,3:1
