1Xiba Granitic Pluton in the Qinling Orogenic Belt, Central China: Its Petrogenesis and Tectonic Implications显示文摘Xiba granitic pluton is located in South Qinling tectonic domain of the Qinling orogenic belt and consists mainly of granodiorite and monzogranite with significant number of microgranular quartz dioritic enclaves. SHRIMP zircon U-Pb isotopic dating reveals that the quartz dioritic enclaves formed at 214±3 Ma, which is similar to the age of their host monzogranite (218±1 Ma). The granitoids belong to high-K calc-alkaline series, and are characterized by enriched LILEs relative to HFSEs with negative Nb, Ta and Ti anomalies, and right-declined REE patterns with (La/Yb) N ratios ranging from 15.83 to 26.47 and δEu values from 0.78 to 1.22 (mean= 0.97). Most of these samples from Xiba granitic pluton exhibit εNd(t) values of 8.79 to 5.38, depleted mantle Nd model ages (T DM ) between 1.1 Ga and 1.7 Ga, and initial Sr isotopic ratios ( 87 Sr/ 86 Sr) i from 0.7061 to 0.7082, indicating a possible Meso-to Paleoproterozoic lower crust source region, with exception of samples XB01-2-1 and XB10-1 displaying higher ( 87 Sr/ 86 Sr) i values of 0.779 and 0.735, respectively, which suggests a contamination of the upper crustal materials. Quartz dioritic enclaves are interpreted as the result of rapid crystallization fractionation during the parent magmatic emplacement, as evidenced by similar age, texture, geochemical, and Sr-Nd isotopic features with their host rocks. Characteristics of the petrological and geochemical data reveal that the parent magma of Xiba granitoids was produced by a magma mingling process. The upwelling asthenosphere caused a high heat flow and the mafic magma was underplated into the bottom of the lower continent crust, which caused the partial melting of the lower continent crustal materials. This geodynamic process generated the mixing parent magma between mafic magma from depleted mantle and felsic magma derived from the lower continent crust. Integrated petrogenesis and tectonic discrimination with regional tectonic evolution of the Qinling orogen, it is suggested that the granitoids are most likely products in a post-collision tectonic setting.ZHANG Fan LIU Shuwen CHEN Xu LI Qiugen DAI Junzhi YANG Kai WU Fenghui CHEN Youzhang 2012Acta Geologica Sinica(English Edition)2012,86,5:13
2Analysis of threshed rice mixture separation through vibration screen using discrete element method显示文摘The discrete element method was utilized to construct three-dimensional discrete element models for the rice mixture,and their motions were analyzed numerically on a planar vibration screening device.The results showed that,after falling onto the vibrating screen surface,the mixture undergoes a reciprocating motion within the same cycle.During the screening process,the mixture undergoes segregation,slides along the screen surface,passes through the screen and then falls.In comparing the movement of grains and shriveled grains,it can be seen that the velocity of shriveled grains experiences cyclical changes,which is consistent with the grains’motion cycle.The impact on grains is shown to be greater than that on shriveled grains,and the average speeds of shriveled grains and grains converge.The curve shows that the screening of repetitive movements has a significant effect on the average velocity of shriveled grains,but also the velocity of shriveled grains and the vibration parameters can be well represented by a fitting equation.It is beneficial for the separation of grains from shriveled grains to choose a greater vibration frequency and screen surface inclination in the range of commonly used.Li Hua Wang Jinshuang Yuan Jianbo Yin Wenqing Wang Zhiming Qian Youzhang 2017International Journal of Agricultural and Biological Engineering2017,10,6:10
3Critical Range of Soil Boron for Prognosis of Boron Deficiency in Oilseed Rape显示文摘Relationships between seed yields of oilseed rape (Brassica napus L.) and extractable boron concentrations in three soil layers (A, P and W) were investigated through ten experiments on three types of soils (Alluvic Entisols, Udic Ferrisols and Stagnic Anthrosols) in northern, western and middle Zhejiang Province. Among several mathematical models used to described the relationships, the polynomial equation, y = a + bx + cx2 + dx3, where y is the yield of oilseed rape seed and x the extractable boron concentration in P layer of soil, was the best one. The critical range of the concentrations corresponding to 90% of the maximum oilseed rape yield was 0.40-0.52 mg kg-1. The extractable boron concentration of the P layers of the soils was the most stable. The critical range determined was verified through the production practices of oilseed rape in Zhejiang and Anhui provinces.WEI YOUZHANG Department of Soil Science and Agricultural Chemistry, Zhejiang University, Hangzhou 310029 (China) 2001Pedosphere2001,11,3:6
4Protective effect of Sijunzi decoction on neuromuscular junction ultrastructure in autoimmune myasthenia gravis rats显示文摘OBJECTⅣE: To investigate the protective role of Sijunzi decoction in neuromuscular junction(NMJ)and muscle cell mitochondria ultrastructure; as well as its effects on the amount of adenosine triphosphate(ATP) and the activities of mitochondrial respiratory chain complexes I, Ⅱ, Ⅲ, and Ⅳ in autoimmune myasthenia gravis rats.METHODS: An experimental autoimmune myasthenia gravis(EAMG) rat model was established by inoculating rats with acetylcholine receptors extracted from Torpedo. Rats were divided into three groups: model, prednisone, and Sijunzi decoction, and were fed physiological saline, prednisone, or Sijunzi decoction, respectively. NMJ and muscle cell mitochondria ultrastructure were observed by transmission electron microscope. The amount of ATP was assessed by high performance liquid chromatography. The activities ofmitochondrial respiratory chain complexes I, Ⅱ, Ⅲ,and Ⅳ was determined using the Clark oxygen electrode method.RESULTS: In the model group, there were sparse muscle fibers, with decreased mitochondria, and sparse, diffluent, or absent NMJ folds. After intervention with Sijunzi decoction, the above pathology changes were improved: muscle fiber structure was clear and complete; the mitochondria count was higher; and the NMJ structure was close to normal. Gastrocnemius muscle mitochondria in the model group produced significantly less ATP than those in the prednisone group(P<0.01). Conversely, the ATP of Sijunzi decoction group was significantly higher than prednisone group(P<0.01). The activities of gastrocnemius muscle mitochondrial respiratory chain complexes I, Ⅱ, Ⅲ, and Ⅳ in both the prednisone and Sijunzi decoction groups was dramatically higher compared with the model group(P<0.05). The activities of complexes I and Ⅲ in the Sijunzi decoction group were significantly higher than those in the prednisone group(P<0.05), but there was no obvious difference in complex Ⅱ or Ⅳ activities between the two groups(P>0.05).CONCLUSION: Sijunzi decoction improved pathological changes in muscle mitochondria and NMJ,enhanced the amount of ATP in gastrocnemius muscle mitochondria, and improved the activities of respiratory chain complexes I, Ⅱ, Ⅲ, and Ⅳ(especially I and Ⅲ) of the EAMG rats.HaibinWu Shifeng She Youzhang Liu Wensheng Xiong Yalei Guo Huansong Fang Hong Chen Jia Li 2013Journal of Traditional Chinese Medicine2013,33,5:3
5Dual-Functional Lithiophilic/Sulfiphilic Binary-Metal Selenide Quantum Dots Toward High-Performance Li-S Full Batteries显示文摘The commercial viability of lithium-sulfur batteries is still challenged by the notorious lithium polysulfides(Li PSs)shuttle effect on the sulfur cathode and uncontrollable Li dendrites growth on the Li anode.Herein,a bi-service host with Co-Fe binary-metal selenide quantum dots embedded in three-dimensional inverse opal structured nitrogen-doped carbon skeleton(3DIO FCSe-QDs@NC)is elaborately designed for both sulfur cathode and Li metal anode.The highly dispersed FCSe-QDs with superb adsorptive-catalytic properties can effectively immobilize the soluble Li PSs and improve diffusion-conversion kinetics to mitigate the polysulfide-shutting behaviors.Simultaneously,the 3D-ordered porous networks integrated with abundant lithophilic sites can accomplish uniform Li deposition and homogeneous Li-ion flux for suppressing the growth of dendrites.Taking advantage of these merits,the assembled Li-S full batteries with 3DIO FCSe-QDs@NC host exhibit excellent rate performance and stable cycling ability(a low decay rate of 0.014%over 2,000 cycles at 2C).Remarkably,a promising areal capacity of 8.41 mAh cm^(-2)can be achieved at the sulfur loading up to 8.50 mg cm^(-2)with an ultra-low electrolyte/sulfur ratio of 4.1μL mg^(-1).This work paves the bi-serve host design from systematic experimental and theoretical analysis,which provides a viable avenue to solve the challenges of both sulfur and Li electrodes for practical Li-S full batteries.Youzhang Huang Liang Lin Yinggan Zhang Lie Liu Baisheng Sa Jie Lin Laisen Wang Dong-Liang Peng Qingshui Xie 2023Nano-Micro Letters2023,15,5:2

7Bi_(2)S_(3) spheres coated with MOF-derived Co_(9)S_(8) and N-doped carbon composite layer for half/full sodium-ion batteries with superior performance显示文摘Bismuth sulfide(Bi_(2)S_(3))has attracted particular interest as a potential anode material for sodium-ion batteries(SIBs).However,the low electrical conductivity and dramatic volumetric change greatly restrict its practical applications.In view of the apparent structural and compositional advantages of metal-organic frameworks(MOFs)derived carbon-based composite,herein,as a proof of concept,Bi_(2)S_(3) spheres coated with the MOF-derived Co_(9)S_(8) and N-doped carbon composite layer(Bi_(2)S_(3)@Co_(9)S_(8)/NC composite spheres)have been rational designed and synthesized.As expected,the core-shell Bi_(2)S_(3)@Co_(9)S_(8)/NC composite spheres exhibit remarkable electrochemical performance in terms of high reversible capacity(597 m Ah g^(-1) after 100 cycles at 0.1 A g^(-1)),good rate capability(341 m Ah g^(-1) at 8 A g^(-1))and long-term cycling stability(458 m Ah g^(-1) after 1000 cycles at 1 A g^(-1))when investigated as anode materials for SIBs.Electrochemical analyses further reveal the favorable reaction kinetics in the Bi_(2)S_(3)@Co_(9)S_(8)/NC composite spheres.In addition,the possible sodium storage mechanism has been studied by ex-situ X-ray diffraction technique.More importantly,a sodium-ion full cell based on Na_(3) V_(2)(PO_(4))_(3)/r GO as cathode and Bi_(2)S_(3)@Co_(9)S_(8)/NC as anode is also fabricated,suggesting their potential for practical applications.It is anticipated that the present work could be extended to construct other advanced electrode materials using MOFs-derived carbon-based composites as surface coating materials for various energy storagerelated applications.Youzhang Huang Xueshuang Zhu Daoping Cai Zhixiang Cui Qianting Wang Hongbing Zhan 2021Journal of Energy Chemistry2021,30,8:2
