| 2 | Zircon U-Pb geochronology,geochemistry and petrogenesis of syenogranite from Angeer Yinwula area in Inner Mongolia显示文摘The study presents the results of U-Pb dating of zircons and whole-rock geochemical analyses of syenogranite in Angeer Yinwula area, China, with the aim of determining its formation time, petrogenesis and regional setting. Zircon U-Pb data obtained by LA-ICP-MS indicate that the syenogranite formed in the Early Cretaceous(136.1±0.9 Ma). Geochemically, the rock is characterized by high SiO_2(76.63%--77.58%) and Na_2O+K_2O(8.00%--8.32%), low MgO(0.02%--0.04%) and TFe_2O_3(0.51%--0.84%), and is enriched in LREEs and LILEs, depleted in HREEs and HFSEs. It belongs to high-K calc-alkaline, metaluminous-weakly peraluminous, exhibiting an affinity to I-type granite. All these characteristics implied that the syenogranite in this region derived from crust-mantle mixed source. Overall, the regional geology, geochronology and geochemical features suggest that the formation of the syenogranite was related to the subduction of the Paleo-Pacific Ocean. | LIU Hanlun WANG Keyong LI Jian CAI Wenyan TANG Wenhao WANG Changhong | 2019 | Global Geology2019，22，2： | 2 |
| 3 | Thermodynamic Performances of[mmim]DMP/Methanol Absorption Refrigeration显示文摘In order to study the theoretical cycle characteristic of [mmim]DMP(1-methyl-3-methylimidazolium dimethylphosphate)/methanol absorption refrigeration,the modified UNIFAC group contribution model and the Wilson model are established through correlating the experimental vapor pressure data of [mmim]DMP/methanol at T=280~370K and methanol mole fraction x=0.529~0.965.Thermodynamic performances of absorption refrigeration utilizing [mmim]DMP/methanol,LiBr/H2O and H2O/NH3 are investigated and compared with each other under the same operating conditions.From the results,some conclusions are obtained as follows:1)the circulation ratio of the [mmim]DMP /methanol absorption refrigeration is higher than that of the LiBr/H2O absorption refrigeration,but still can be acceptable and tolerable.2)The COP of the [mmim]DMP/methanol absorption refrigeration is smaller than that of the LiBr/H2O absorption refrigeration,while it is higher than that of the H2O/NH3 absorption refrigeration under most operating conditions.3)The[mmim]DMP/methanol absorption refrigeration are still available with high COP when the heat source temperature is too high to drive LiBr/H2O absorption refrigeration. | Wei Chen Shiqiang Liang Yongxian Guo Keyong Cheng Xiaohong Gui Dawei Tang | 2012 | Journal of Thermal Science2012，21，6： | 2 |
| 4 | Kinetics and mechanism of thermal degradation of vegetable-tanned leather fiber显示文摘Thermal degradation of vegetable-tanned leather fiber(VLF)was investigated by thermogravimetric analysis aiming to know the exact kinetics and degradation mechanism.The thermogravimetric(TG)and differential thermogravimetric(DTG)curves showed that decomposition of the VLF occurs mainly in the range of 150-600℃,and the latter exhibits asymmetrical peak with a pronounced shoulder.The decomposition process was first analyzed by deconvolution of the experimental DTG curves,followed by reconstruction of the weight loss profiles of two individual processes.Several common isoconversional approaches were applied to calculate the activation energy over a wide range of conversion for the sample,including modified Kissinger-Akahira-Sunose(MKAS),Friedman,and Flynn-Wall-Ozawa.The average activation energy of vegetable-tanned leather fiber was found to be 241.9 kJ mol^(−1) by MKAS method.The activation energy values obtained for the pseudocomponents representing highly-crosslinked and low-crosslinked collagen in VLF were given as 190.6 and 124.8 kJ mol^(−1),respectively.Generalized master plots results suggested that the reaction mechanism for highly-crosslinked collagen follows the random nucleation and growth process at conversion values lower than 0.5.When the conversion is higher than 0.5,the mechanism tends to random scission model.For low-crosslinked collagen,the degradation is mainly governed by random nucleation and nuclei growth.The gaseous products of VLF thermal degradation were analyzed with an online-coupled TG-Fourier transform infrared spectroscopy system. | Jie Liu Lan Luo Yadi Hu Fang Wang Xuejing Zheng Keyong Tang | 2019 | Journal of Leather Science and Engineering2019，1，1： | 2 |

| 7 | 离子液体中胶原纤维的溶解和再生显示文摘天然胶原纤维被成功地溶解于1-丁基-3-甲基咪唑氯化物([BMIM]Cl)离子液体中,并且在不同的沉淀剂中再生。在偏光显微镜中观察,发现胶原纤维的晶体结构在加热过程中已经被[BMIM]Cl破坏了。利用变温红外光谱法检测溶解过程中胶原/[BMIM]Cl的结构变化。利用FTIR和XRD表征再生胶原的结构。结果表明,胶原蛋白的三螺旋结构在溶解与再生过程中一定程度上被破坏了。沉淀的处理很大程度上决定了再生胶原的成膜能力和热稳定性,提出了胶原在[BMIM]Cl中溶解以及在沉淀剂中再生的可能机制。利用[BMIM]Cl作为介质可以成功制备不同形态(薄膜,纤维,凝胶)的胶原蛋白/纤维素复合材料。 | Zhuojun Meng Xuejing Zheng Keyong Tang 徐彬 王国伟 | 2014 | 西部皮革2014，36，14： | 1 |
| 8 | Interface engineering of Fe-Co_(3)N/CoP composite with N-doped C by using soybean:Fabrication of efficient electrocatalysts for oxygen evolution reaction显示文摘Soybean can serve as an efficient carbon and nitrogen source for in-situ fabrication of efficient composite electrocatalysts with conductive nitrogen-doped carbon(N-C)material.In this study,the iron-doped cobalt nitride/phosphide(Fe-Co_(3)N/CoP)nanosheet was composited with a conductive N-C material by using soybean as C and N source,as well as NH3 as additional nitrogen source.During the nitridation process of Fe-Co_(3)N,N-C bond was formed as a newly generated Co(Fe)-N-C active sites.Therefore,it fabricates a good microscopic contact interface between the catalyst and carbon material for charge transfer.Besides,the introduction of Fe-CoP by partially phosphating Fe-Co_(3)N further improved the OER activity due to the high catalytic activity of Co sites with high valence state.As a result,the obtained electrocatalyst exhibited overpotentials as low as 285 and 390 mV for supporting 10 and 100 mA/cm��2 current densities.This work indicates that the design of materials with good interfaces could be an effective approach for the preparation of electrocatalysts for water electrolysis. | Longqing Gao Xiumin Li Chao Tang Tianshuo Xie Zhengkun Xie Haimei Li Guoqing Guan Jie Liu Keyong Tang | 2023 | Carbon Resources Conversion2023，6，2： | 1 |

| 10 | Efficient and ecological leather processing: replacement of lime and sulphide with dispase assisted by 1-allyl-3-methylimidazolium chloride显示文摘Leather is a collagen-based biomass prepared from raw skins or hides by a series of unit operations, in which the unhairing and fiber opening are extremely important operations. However, the conventional Na2S/Ca(OH)2 system used in unhairing and fiber opening has given rise to the pollution to the environment. It is necessary to develop substitute technology for the Na2S/Ca(OH)2. In the present study, 1-allyl-3-methylimidazolium chloride ([AMIm]Cl) was used to cooperate with dispase for cycle unhairing and one-pot beamhouse to recycle waste bovine hides and com-pared with conventional processing. During those processes, the mechanism of [AMIm]Cl-dispase synergistic unhair-ing and collagen fibers opening were studied. Besides, plant hazard, organic matter and [AMIm]Cl of wastewater from [AMIm]Cl-dispase process were respectively investigated and separated to evaluate the environmental and economic benefits of the [AMIm]Cl-dispase process. As a result, enzyme activity after unhairing by [AMIm]Cl-diapase system for using 5 times is higher than that by KCl-dispase system, and needs lower unhairing time, which is because of rapid penetration of [AMIm]Cl-dispase solution in bovine hides. For this reason, the tensile strength and elastic modulus of tanned leather from [AMIm]Cl-dispase process are higher than those from the KCl-diapase and conventional pro-cesses, and its hydrothermal shrinkage temperature is comparable to that of the conventional one. Because of the 58.13% lower wastewater discharge (WD), 66.60% lower total solids (TS), 97.23% lower ammonia nitrogen (NH3-N), non-toxic wastewater and organic matter recovery in wastewater are reached from [AMIm]Cl-dispase process, which is expected to be an alternative to the conventional process to reduce environmental pollution and realize the sustainable development of technology for leather manufacturing. | Hui Liu Keyong Tang Xiumin Li Jie Liu Xuejing Zheng Ying Pei | 2022 | Journal of Leather Science and Engineering2022，4，1： | 0 |
| 11 | Food Supply Values and Their Factors of Three Pond Aquaculture Ecosystems: A Case Study of Shanghai显示文摘Studies on food supply values,the basis of eco-service values,and their factors of different pond aquaculture ecosystems are helpful to explain the influences of the inputted factors and their variations among these ecosystems and provide information for stakeholders to adjust their decisions and behaviors to increase their total eco-service values. On the basis of continued records from 2011 to 2012 of 18 ponds of three pond aquaculture ecosystems,namely Litopenaeus vannamei,Macrobrachium nippponensis and carp fresh water pond aquaculture ecosystems in Qingpu,Fengxian,and Jiading,three suburban districts of Shang,this paper analyzed the costs,returns,net food supply values and their regional and temporal fluctuations. The results showed that:(1) the net food supply values of the three ecosystems are 143252. 4,135883. 7,and 52623. 1Yuan /Ha in 2011 correspondently,with the Litopenaeus vannamei pond aquaculture ecosystem(LVPAE) ranking highest and the carp pond aquaculture ecosystem(CPAE) lowest among them,and the trend was same in 2012,but the values decreased than that of 2011 with the rate of 30. 0%( LVPAE),38. 0 %( Macrobrachium nippponensis pond aquaculture ecosystem,MNPAE) and 13. 7 %( CPAE).(2)The dominant factors of the net food supply values of these ecosystems are the produce price and variable costs; fry and feed costs are the main variable factors producing the noticeable difference among the ecosystems.(3) The cost- benefit ratio of per unit product of the CPAE,LVPAE and MNPAE changed from 27. 5%,91. 7%,129. 0% in 2011 to 23. 0%,73. 8% and 63. 8% in 2012,with the CPAE ranked lowest among them in both years.(4) For all the three ecosystems,their net food supply values may not always change in same trends with their net eco-service values,if stakeholders want to keep a balance between these two types of values,MNPAE should be encouraged in these districts. | Zhengyong YANG Xinzheng ZHANG Zhenfang HAN Keyong TANG | 2014 | Asian Agricultural Research2014，6，8： | 0 |

| 13 | Generation of oxygen vacancies in NiFe LDH electrocatalysts by ultrasound for enhancing the activity toward oxygen evolution reaction显示文摘Introduction of vacancies is a promising route to enhance the performance of electrocatalysts by tuning the electronic structure and bonding energy.Here,the influence of ultrasound treatment on the O vacancies formation and interlayer spacing in NiFe layered double hydroxide(LDH)was investigated.It is found that the strong ultrasound treatment results in rich O vacancies on the surface of NiFe LDH,which affect the electrocatalysis performance.Besides,the ultrasound treated NiFe LDH electrocatalysts had a reduced thickness with a hexagonal nanosheet morphology and expanded interlayer distance,which could promote the diffusion of reactant and generated gas.When the obtained defect-rich NiFe LDH electrocatalyst prepared by a 10-min ultrasonic treatment was applied to catalyze oxygen evolution reaction(OER),only 194 mV of overpotential was needed to maintain a current density of 10 mA⋅cm^(-2). | Xiumin Li Qianyu Hu Yazhou Xu Xiaoyang Liang Jiawei Feng Kunyan Zhao Guoqing Guan Yongchao Jiang Xiaogang Hao Keyong Tang | 2021 | Carbon Resources Conversion2021，4，1： | 0 |

| 15 | A combined kinetic study on the pyrolysis of chrome shavings by thermogravimetry显示文摘Chrome shavings(CS),a kind of solid wastes discharged from tanneries,always pose serious environmental problems due to the presence of chromium.In this work,kinetic study of the pyrolysis of CS was investigated using a thermogravimetric analyzer in nitrogen atmosphere.The results obtained from the thermogravimetric analysis indicated that there are three stages in the temperature range 25 to 600℃.The second stage is the main weight loss stage and it could be mainly attributed to the pyrolysis of collagenous materials.Iso-conversional and generalized master-plots method were first employed to estimate the activation energy value and possible reaction mechanism of CS pyrolysis.The results showed that the pyrolysis process could not be described accurately by single-step reaction due to the heterogeneous nature of CS.Afterwards,the thermogravimetric kinetic of CS pyrolysis was studied using combined kinetic analysis.It was found that three-parallel-reaction model allowed better fitting relevance for CS pyrolysis.This information was important for simulating and predicting the pyrolysis behaviors of CS. | Jie Liu Lan Luo Zonghui Zhang Yadi Hu Fang Wang Xiumin Li Keyong Tang | 2020 | Carbon Resources Conversion2020，3，1： | 0 |
