1Effect of Strontium Addition to Platinum Catalyst for Propane Dehydrogenation显示文摘PtSnSr/HZSM-5 catalysts with different amounts of strontium were prepared by sequential impregnation method,and characterized by BET analysis,TEM,NH3-TPD,H2-TPR,TPO and TG techniques.The results showed that the addition of strontium could modify the characteristics and properties of both acid function and metal function of Pt-Sn-based catalysts.In this case,PtSnSr/HZSM-5 catalyst with an appropriate amount of Sr(1.2%) showed higher catalytic activity and lower amount of coke deposits than PtSn/HZSM-5 catalyst.However,excessive loading of Sr could facilitate the reduction of Sn,which was unfavorable to the reaction.Afterwards,1.0 m% of Na was added into the PtSnSr(1.2%)/HZSM-5 catalyst to improve the catalytic performance in propane dehydrogenation,and this catalyst displayed the best catalytic performance during our experiments.After having been subjected to reaction for 5h,the PtSnNa(1.0%)Sr(1.2%)/HZSM-5 catalyst had achieved a higher than 95% selectivity towards propene along with a corresponding propane conversion rate of 32.2%.Huang Li Zhou Shijian Zhou Yuming Zhang Yiwei Zhang Shaobo Xu Jun 2012China Petroleum Processing & Petrochemical Technology2012,14,3:11
2Potential Benefits of Biochar in Agricultural Soils:A Review显示文摘Soil degradation,characterized by declines in nutrient status and simultaneous accumulation of pesticide residues,is a major problem affecting agricultural ecosystems.Previous studies indicate that biochar application to soil has promise as a practical method to alleviate these pressures:increasing crop yield and enhancing pesticide degradation.Here,we review the roles of biochar in both chemical and biological promotion of pesticide degradation and the potential benefits of biochar relating to the efficiency of fertilizer use,availability of nutrients,and nutrient exchange.Biochar typically has a high surface area featuring many functional groups,a high cation exchange capacity,and high stability.Major factors that impact on the nutrient retention characteristics of biochar(e.g.,feedstock,pyrolysis temperature,and application rate) are also discussed herein.Nonetheless,more studies of the long-term impacts on soil properties from biochar addition are still required before it can be possible to accurately quantify the sustainability of this approach to sequester carbon and restore soil function.DING Yang LIU Yunguo LIU Shaobo HUANG Xixian LI Zhongwu TAN Xiaofei ZENG Guangming ZHOU Lu 2017Pedosphere2017,27,4:10
3Interfacial microstructure evolution and bonding mechanisms of 14YWT alloys produced by hot compression bonding显示文摘Hot compression bonding was first used to join oxide-dispersion-strengthened ferrite steels(14 YWT)under temperatures of 750–1100℃ with a true strain range of 0.11–0.51. Subsequently, the microstructure evolution and mechanical properties of the joints were characterized, revealing that the 14 YWT steels could be successfully bonded at a temperature of at least 950℃ with a true strain of 0.22, without degrading the fine grain and nanoparticle distribution, and the presence of inclusions or micro-voids along the bonding interface. Moreover, the joints had nearly the same tensile properties at room temperature and exhibited a similar fracture morphology with sufficient dimples compared to that of the base material. An electron backscattered diffraction technique and transmission electron microscopy were systematically employed to study the evolution of hot deformed microstructures. The results showed that continuous dynamic recrystallization characterized by progressive subgrain rotation occurred in this alloy, but discontinuous dynamic recrystallization characterized by strain-induced grain boundary bulging and subsequent bridging sub-boundary rotation was the dominant nucleation mechanism. The nuclei will grow with ongoing deformation, which will contribute to the healing of the original bonding interface.Liying Zhou Shaobo Feng Mingyue Sun Bin Xu Dianzhong Li 2019Journal of Materials Science & Technology2019,35,8:6
4Structure-function relationship of the mammarenavirus envelope glycoprotein显示文摘Mammarenaviruses, including lethal pathogens such as Lassa virus and Junín virus, can cause severe hemorrhagic fever in humans. Entry is a key step for virus infection, which starts with binding of the envelope glycoprotein(GP) to receptors on target cells and subsequent fusion of the virus with target cell membranes. The GP precursor is synthesized as a polypeptide, and maturation occurs by two cleavage events, yielding a tripartite GP complex(GPC) formed by a stable signal peptide(SSP), GP1 and GP2. The unique retained SSP interacts with GP2 and plays essential roles in virion maturation and infectivity. GP1 is responsible for binding to the cell receptor, and GP2 is a class I fusion protein. The native structure of the tripartite GPC is unknown.GPC is critical for the receptor binding, membrane fusion and neutralization antibody recognition.Elucidating the molecular mechanisms underlining the structure–function relationship of the three subunits is the key for understanding their function and can facilitate novel avenues for combating virus infections. This review summarizes the basic aspects and recent research of the structure–function relationship of the three subunits. We discuss the structural basis of the receptor-binding domain in GP1, the interaction between SSP and GP2 and its role in virion maturation and membrane fusion, as well as the mechanism by which glycosylation stabilizes the GPC structure and facilitates immune evasion. Understanding the molecular mechanisms involved in these aspects will contribute to the development of novel vaccines and treatment strategies against mammarenaviruses infection.Wei Wang Zheng Zhou Leike Zhang Shaobo Wang Gengfu Xiao 2016Virologica Sinica2016,31,5:4

8Optimal design of the gas storage surface pipeline system with injection and withdrawal conditions显示文摘Underground natural gas storage(UNGS)is an important part of the natural gas supply system to ensure a balanced energy supply.The surface system,as an important part of the gas storage,undertakes the functions of gas injection and gas production of the gas storage,and its investment economy is of vital importance.In fact,the UNGS surface pipeline network has two-way injection and production characteristics,which is different from the one-way production characteristics of conventional oil&gas gathering and transportation systems.This paper takes the minimum investment of the pipeline network as the objective function,considers the gas injection and gas withdrawal flow conditions and esablishes a mixed integer non-linear programming model(MINLP)for the surface pipeline network of the UNGS to optimize its pipeline layout and diameter parameters.Constraints including the well affiliation,the number of stations,the gathering radius,the processing capacity and the flow/pressure equilibrium equations,are also taken into consideration.Taking an UNGS in China as an example,the results of the optimal structure and diameter of the pipeline network,as well as the pipe flow,node pressure,and maximum/minimum flowrate during gas injection and gas withdrawal are obtained.Finally,the effects of constraints such as processing capacity and radius on the structure layout and investment of the UNGS are analyzed,verifying the reliability and effectiveness of the model.Jun Zhou Liuling Zhou Guangchuan Liang Shaobo Wang Tiantian Fu Xuan Zhou Jinghong Peng 2021Petroleum2021,7,1:2
9CILP-2 is a novel secreted protein and associated with insulin resistance显示文摘Genetic association studies have implicated that cartilage intermediate layer protein 2 (CILP-2) confers the risk susceptibility for type 2 diabetes (T2DM). However, it is still unknown whether CILP-2 is involved in the regulation of glucose homeostasis and insulin resistance (IR). In the current study, we initially observed that CILP-2 as a secreted protein was detected in both conditioned medium and lysates of cells transfected with an overexpressed vector. We then found that circulating CILP-2 levels had a progressive increase from normal to impaired glucose tolerance (a pre-diabetic status) and then to diabetes, which was correlated positively with waist-to-hip ratio, triglyceride, fasting blood glucose, 2-h blood glucose after glucose overload, HbA1c, fasting insulin, 2-h plasma insulin after glucose overload, and homeostasis model assessment of insulin resistance but negatively with HDL-C. CILP-2 expression was increased in the liver and muscle but decreased in adipose tissues of obese mice or T2DM patients. Furthermore, we demonstrated that CILP-2 circulating levels were affected by OGTT and Exenatide. CILP-2 overexpression resulted in impaired glucose tolerance and hepatic IR in vivo and increased PEPCK expression whereas suppressed phosphorylation of insulin receptor and Akt kinase in vitro. Based on these findings, we have identified a direct interaction between CILP-2 and PEPCK and suggested that CILP-2 plays an important role in the regulation of hepatic glucose production.Tong Wu Qin Zhang Shaobo Wu Wenjing Hu Tingting Zhou Ke Li Dongfang Liu Harvest FGu Hongting Zheng Zhiming Zhu Ling Li and Gangyi Yang 2019Journal of Molecular Cell Biology2019,11,12:2

11A scalable bio-inspired polydopamine-Cu ion interfacial layer for high-performance lithium metal anode显示文摘The growth of Li dendrites and the instability of the solid electrolyte in terphase(SEI)layer during plating/stripping has hin dered the practical applicati on of high-energy-density batteries based on a lithium metal anode.Building a stable interfacial layer is effective in preventing lithium corrosiion by the electrolyte and controlling the deposition of lithium metal.Here,we present a robust polydopamine-Cu ion(PDA-Cu^2+)coati ng layer formed by the aggregation of nanoparticles and Cu ions,which can be obtained by a subtle immersion strategy.We demonstrate that the PDA-Cu^2+ protective layer,with a unique structure comprising nanoparticles,can regulate and guide Li metal deposition,and together with Cu ions,forms a lubricating surface to facilitate uniform Li ion diffusion and induce stable SEI layer formation.Li anodes with this PDA-Cu^2+layer modification ultimately achieve higher Coulombic efficiencies,which are consistently stable for over 650 cycles at 0.5 mA·cm^-2 without Li dendrites.The introduced PDA-Cu^2+ coating can adhere to any material of any shape;addition ally,the operation can be realized on a large scale because of its simplicity.These merits provide a promising approach for developing stable and safe lithium metal batteries.Qianqian Meng Huimin Zhang Yue Liu Shaobo Huang Tianzhu Zhou Xiaofei Yang Biyan Wang Wenfeng Zhang Hai Ming Yu Xiang Meng Li Gaoping Cao Yaqin Huang Li-zhen Fan Hao Zhang Yuepeng Guan 2019Nano Research2019,12,12:2

16320-fold luminescence enhancement of [Ru(dpp)3]Cl2 dispersed on PMMA opal photonic crystals and highly improved oxygen sensing performance显示文摘Ru complexes([Ru(dpp)3]Cl2)were spin coated on poly(methyl methacrylate)(PMMA)opal photonic crystals(PhCs),and a,320-fold luminescence enhancement was observed compared to that on glass,which is the largest luminescence enhancement of dye molecules by the modulation of three-dimensional(3D)PhCs reported until now.The enhancement mechanism was carefully examined and it was shown that the luminescence of[Ru(dpp)3]Cl2 depended on the molecule concentration and temperature.It can be concluded that the suppressed non-radiative relaxation among the molecules and the field enhancement both contribute significantly to the luminescence enhancement.The PMMA PhC/Ru complex composites were then tested for their intracellular oxygen sensing and cell imaging properties;these composites effectively improved the limit of detection(LOD)and the brightness of the cell images.Pingwei Zhou Donglei Zhou Li Tao Yongsheng Zhu Wen Xu Sai Xu Shaobo Cui Lin Xu Hongwei Song 2014Light(Science & Applications)2014,3,1:1
