| 3 | Coprinus comatus-derived nitrogen-containing biocarbon electrocatalyst with the addition of self-generating graphene-like support for superior oxygen reduction reaction显示文摘The development of nitrogen-rich biomassderived carbon catalysts provides an attractive perspective to substitute for Pt-based electrocatalysts for oxygen reduction reaction(ORR). We here report a facile strategy for synthesis of a nitrogen-doped biocarbon/graphene-like composite electrocatalyst by pyrolyzing a solid-state mixture of coprinus comatus biomass and melamine under nitrogen protection. The graphtic carbon nitride formed by polycondensation of melamine at 600 °C acts as a selfsacrificing template to generate the nitrogen-doped graphene-like sheet, which can function as an inserting agent and self-generating support. The composite catalyst exhibits the most promising catalytic activity towards the fourelectron ORR with a half-wave potential of around 0.83 V(vs. RHE), and more excellent stability and tolerance to methanol/ethanol compared to the commercial Pt/C catalyst. It is interestingly found that both a higher content of nitrogen and a larger ratio of graphitic-nitrogen species,which may derive from self-addition of graphene-like support into the catalyst, can effectively improve the electrocatalytic activity. The planar N group may be the nitrogen functionality that is most responsible for maintaining the ORR activity in alkaline medium. This study can largely encourage the exploration of high-performance carbon-based catalysts from economical and sustainable fungus biomass. | Chaozhong Guo Wenli Liao Zhongbin Li Lingtao Sun Haibo Ruan Qingshan Wu Qinghong Luo Jie Huang Changguo Chen | 2016 | Science Bulletin2016,61,12: | 4 |
| 4 | The synthesis and characterization of a Co-N/C composite catalyst for the oxygen reduction reaction in acidic solution显示文摘A non-precious metal Co-N/C catalyst for the oxygen reduction reaction (ORR) was synthesized by heating a mechanical mixture of cobalt chloride,urea and acetylene black under a nitrogen atmosphere.The catalyst was characterized by XRD and XPS.The electrocatalytic activity in the ORR was evaluated by linear sweep voltammetry in 0.5 mol L-1 H2SO4 solution.The results show that the Co-N/C catalyst aids the reduction of oxygen.The presence of elemental cobalt in the precursor allows nitrogen atoms to embed themselves in the graphite matrix to form pyridinic and graphitic type C-N structures as the ORR active sites.The effect of heat-treating temperature on the catalytic activity was also investigated.The results also show that the Co-N/C catalyst is most active when pyrolyzed at 600℃.The obtained Co-N/C catalyst loses some activity after initial exposure to the H2SO4 solution because of leaching,but is then stable for up to 20 h immersion.The catalyst is also stable when charged,which is supported by the cyclic voltammetry results. | SI YuJun CHEN ChangGuo YIN Wei CAI Hui | 2011 | Chinese Science Bulletin2011,56,11: | 3 |

| 7 | Design and analysis of a dual-stator brushless doubly-fed induction machine with a staggered dual-cage rotor显示文摘In this paper,a new dual-stator brushless doubly-fed induction machine with a staggered dual cage rotor is proposed,with emphasis on the general interconnection rule of the conductor bars for the staggered dual cage rotor.Since the squirrel cage rotor offers the merits of robustness,reliable structure,high slot filling factor,and low rotor resistance comparing to the wound rotor,it is introduced to the dual-stator brushless doubly-fed induction machine to solve the problems of high copper loss and unreliable rotor structure for the dual-stator brushless doubly-fed induction machine with a wound rotor.The originality of this article is to investigate the interconnection rule of conductor bars between the inner and outer cages.The constraint condition that is supposed to be satisfied is deduced by using the rotating magneto-motive force theory,based on which diverse slot/pole combinations are investigated.The performance comparison between the existing and proposed machines is conducted.Finally,a prototype is designed and fabricated.The experimental results verify the effectiveness of the proposed topology. | CHENG Ming ZENG Yu YAN XiaoMing ZHANG ChangGuo | 2022 | Science China(Technological Sciences)2022,65,6: | 2 |

| 10 | Light weight optimization of stratospheric airship envelope based on reliability analysis显示文摘A stratospheric airship is an essential flight vehicle in the aviation field.In this paper,optimal design approach of stratospheric airships is developed to optimize envelope shape considering three failure modes and multidisciplinary analysis models,and could also reduce the mass of a stratospheric airship to be deployed at a specific location.Based on a theoretical analysis,three failure modes of airships including bending wrinkling failure,hoop tearing failure and bending kink failure,are given to describe and illustrate the failure mechanism of stratospheric airships.The results show that the location,length and size of the local uniform load and the large fineness ratio are easier to lead to bending wrinkling failure and bending kink failure.The small fineness ratio and the increasing differential pressure are more prone to cause hoop tearing failure for an airship hull.The failure probability is sensitive to the wind field.From an optimization design,the reliability analysis is essential to be carried out based on the safety of the airship.The solution in this study can provide economical design recommendations. | Yunce ZHANG Yafei WANG Changguo WANG | 2020 | Chinese Journal of Aeronautics2020,33,10: | 2 |

| 14 | Exhumation history and preservation of the Jiaojia giant gold deposit, Jiaodong Peninsula显示文摘The Jiaojia giant gold deposit is the largest gold deposit in China, with a total gold reserve of approximately 1200 t.Until now, the knowledge of the exhumation history of post-mineralization period is limited, in particular for the low-temperature thermochronology studies of samples below-1000 m. In this work, we combined zircon fission-track(ZFT) and apatite fission-track(AFT) dating of samples between-1100 and-2000 m to determine the post-mineralization cooling and exhumation history of the Jiaojia giant gold deposit. The ZFT ages ranged from 144.2±6.3 to 124.4±5.5 Ma, representing the cooling period and the disturbance of ore-forming fluid. The AFT ages ranged from 28.1±2.6 to 16.2±1.0 Ma, recording the exhumation and cooling processes. With reference to previous low-temperature thermochronology studies in the Jiaojia goldfield, we estimated the exhumation rate and amount of the Jiaojia giant gold deposit and reconstructed its exhumation and preservation history. The exhumation history was divided into four stages, rapid exhumation(~120–95 Ma), relatively slow exhumation(~95–50 Ma),slow exhumation(~50–30 Ma) and relatively rapid exhumation(since 30 Ma). Each stage corresponds to geological events related to the basin-mountain coupling that have occurred since the Cretaceous in the Jiaodong area, namely, a strong tectonic extension and volcanic eruption in the Jiaolai Basin, subsidence of the Jiaolai Basin and Wangshi Group molasse sedimentary,tectonic quiescence, and the Linqu Group basalt eruption of the Jiaobei uplift. Our results show that the exhumation of the Jiaojia giant gold deposit is ~5.2±1.2 km and the orebody erosion degree is relatively low, indicating huge prospecting potential deep in the Jiaojia giant gold deposit. These findings have significance and practical value for deep prospecting in the Jiaodong area. | Qibin ZHANG Mingchun SONG Zhengjiang DING Meili GUO Mingling ZHOU Changguo DAI Guang HUO Peng ZHANG | 2022 | Science China Earth Sciences2022,65,6: | 1 |
