| 1 | Xiba 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 | 2012 | Acta Geologica Sinica(English Edition)2012，86，5： | 13 |

| 4 | Photosynthate supply drives soil respiration of Fraxinus mandshurica seedlings in northeastern China: evidences from a shading and nitrogen addition experiment显示文摘Improved understanding of the link between photosynthesis and below-ground processes is needed to better understand ecosystem carbon(C) cycling and its feedback to climate change. We conducted a short-term shading and nitrogen(N) addition experiment from June to September 2013 to investigate the effect of photosynthate supply by Manchurian Ash(Fraxinus mandshurica) seedlings on soil respiration(SR). Shading significantly reduced SR in early and middle growing season, but not in late growing season, leading to a decrease in mean SR by 24 % in N-unfertilized treatments. N addition increased mean SR by 42 % in un-shaded treatment. The stimulation of SR was largely attributed to accelerated autotrophic respiration by increasing photosynthesis, leaf area index and belowground biomass. Shading reduced mean SR by 32 % in N addition treatment. The strengthened shading effect on SR resulted from N addition was because of more photosynthates supply at low soil temperature. Our findings highlight the predominance of photosynthates supply in regulating the responses of C cycling to global change. | Yanli Jing Dexin Guan Jiabing Wu Anzhi Wang Changjie Jin Fenghui Yuan | 2016 | Journal of Forestry Research2016，27，6： | 1 |
| 5 | Hydrothermal synthesis and characterization of MnCo_(2)O_(4) in the low-temperature hydrothermal process:Their magnetism and electrochemical properties显示文摘MnCo_(2)O_(4) octahedral structure with edge length about 500 nm was successfully synthesized by a simple hydrothermal route.With the use of NaOH,the chemical potential and the rate of ionic motion in the precursor solution were controlled,and the particle size was limited.The magnetization measurements revealed that the products exhibited ferrimagnetic characteristics with different saturation magnetization and coercivity at different measuring temperatures.In addition,the as-prepared MnCo_(2)O_(4) as anodes for lithium-ion batteries(LIBs)exhibited a reversible capacity of 1180 mA·h/g and 1090 mA·h/g at current density of 0.1 C and 1 C,respectively.The excellent cyclic performance was confirmed because the value of reversible capacity for MnCo_(2)O_(4) was 618 mA·h/g after 50 cycles at 0.1 C.Owing to the good rate performance,MnCo_(2)O_(4) octahedral products were suggested to have a promising application as anode material for LIBs. | Lianfeng DUAN Fenghui GAO Limin WANG Songzhe JIN Hua WU | 2013 | Journal of Advanced Ceramics2013，2，3： | 0 |
| 6 | High-performance liquid-phase catalytic purification of phosphine in tail gas using Pd(Ⅱ)/Cu(Ⅱ)composite显示文摘Pd/Cu liquid-phase composite was utilized as the catalyst in this study to remove PH_(3) at low temperatures.The anti-heterotoxicity of catalysts in the PH_(3) catalytic oxidation purification process was carefully explored and pioneered.The catalytic performance,thermodynamics,kinetics,and catalytic oxidation mechanism of Pd/Cu liquid-phase catalyst catalytic oxidation of PH_(3) were thoroughly investigated.The results showed that Pd/Cu has a superior catalytic effect on the removal of PH_(3) in the gas mixture under low temperature.With CO as the carrier gas,the removal efficiency of PH_(3) could be maintained at 100%for nearly 450 min,indicating that the Pd/Cu liquid phase catalyst has good resistance to heterotoxicity.According to the thermodynamic,kinetic,and related characterization results of the PH_(3) purification process,the kinetic region of the gas–liquid reaction of PH_(3) absorption by Pd/Cu solution was an interfacial reaction.Pd was the primary catalyst and Cu was the secondary catalyst,and the adsorption of PH_(3)was a primary reaction.PH_(3) was spontaneously oxidized to H_(3)PO_(4) in the Pd/Cu catalytic system during the removal process.Pd was regenerated by O_(2) and Cu,increasing the activity and stability of the Pd/Cu catalyst in the sustain and efficient purification of PH_(3) in tail gas. | Chenyang Zhao Yinhan Cheng Guangfei Qu Yongheng Yuan Fenghui Wu Ye Liu Shan Liu Junyan Li Ping Ning | 2023 | Chinese Journal of Chemical Engineering2023，57，5： | 0 |
