| 1 | Influence of N on precipitation behavior,associated corrosion and mechanical properties of super austenitic stainless steel S32654显示文摘The influence of N on the precipitation behavior,associated corrosion,and mechanical properties of S32654 were investigated by microstructural,electrochemical,and mechanical analyses.Increasing the N content results in several alterations:(1) grain refinement,which promotes intergranular precipitation;(2) a linear increase in the driving force for Cr2 N and Mo activity,which accelerates the precipitation of intergranular Cr2 N and π phase,respectively;(3) a linear decrease in the driving force for σ phase and Cr activity,which suppresses the formation of intragranular σ phase.The total amount of precipitates first decreased and then increased with the N content increasing.Furthermore,the intergranular corrosion susceptibility depended substantially on the total amount of precipitates and also first exhibited a decreasing and then an increasing trend as the N content increased.In addition,aging precipitation caused a considerable decrement in the ultimate tensile strength(UTS) and a remarkable increment in the yield strength(YS).Both the UTS and YS always increased with N content increasing throughout the solution and aging process.Whereas the elongation was considerably sensitive to the aging treatment,it exhibited marginal variation with the N content increasing. | Shucai Zhang Huabing Li Zhouhua Jiang Zhixing Li Jingxi Wu Binbin Zhang Fei Duan Hao Feng Hongchun Zhu | 2020 | Journal of Materials Science & Technology2020，42，7： | 10 |
| 2 | Heavy Oil and Oil Sands:Global Distribution and Resource Assessment显示文摘Global recoverable resources of heavy oil and oil sands have been assessed by CNPC using a geology-based assessment method combined with the traditional volumetric method, spatial interpolation method, parametric-probability method etc. The most favourable areas for exploration have been selected in accordance with a comprehensive scoring system. The results show:(1) For geological resources, CNPC estimate 991.18 billion tonnes of heavy oil and 501.26 billion tonnes of oil sands globally, of which technically recoverable resources of heavy oil and oil sands comprise 126.74 billion tonnes and 64.13 billion tonnes respectively. More than 80% of the resources occur within Tertiary and Cretaceous reservoirs distributed across 69 heavy oil basins and 32 oil sands basins. 99% of recoverable resources of heavy oil and oil sands occur within foreland basins, passive continental-margin basins and cratonic basins.(2) Since residual hydrocarbon resources remain following large-scale hydrocarbon migration and destruction, heavy oil and oil sands are characterized most commonly by late hydrocarbon accumulation, the same basin types and source-reservoir conditions as for conventional hydrocarbon resources, shallow burial depth and stratabound reservoirs.(3) Three accumulation models are recognised, depending on basin type: degradation along slope; destruction by uplift; and migration along faults.(4) In addition to mature exploration regions such as Canada and Venezuela, the Volga-Ural Basin and the Pre-Caspian Basin are less well-explored and have good potential for oil-sand discoveries, and it is predicted that the Middle East will be an important region for heavy oil development. | LIU Zuodong WANG Hongjun Graham BLACKBOURN MA Feng HE Zhengjun WEN Zhixing WANG Zhaoming YANG Zi LUAN Tiansi WU Zhenzhen | 2019 | Acta Geologica Sinica(English Edition)2019，93，1： | 9 |

| 8 | Evolution of the morphology,structural and thermal stability of LiCoO_(2) during overcharge显示文摘The overcharge behaviors of 1000 m Ah LiCoO_(2)/graphite pouch cells are systematically investigated through the analysis of morphology,structural and thermal stability of LiCoO_(2) under different state of charge(SOC)of 120%,150%,174%,190%and 220%.The LiCoO_(2) experiences the phase transition from O3 to H1-3 and then O1 together with the grain breakage and boundary slip as evidenced by XRD and SEM analysis respectively,which results in the pronounced Co dissolution after the SOC of 174%.The impedance analysis of the pouch cells and coin cells demonstrates that the main contribution of impedance increase originates from the LiCoO_(2) electrode.Under the combined effect of structural collapse,Co dissolution,and electrolyte oxidization,the thermal stability of Li CoO_(2) cathode materials reduces with the progressing of overcharge as revealed by differential scanning calorimetry(DSC)results.We hope that this comprehensive understanding can provide meaningful guidance for advancing the overcharge performance of LiCoO_(2)/graphite pouch cells. | Zhitao E Huajun Guo Guochun Yan Jiexi Wang Rukun Feng Zhixing Wang Xinhai Li | 2021 | Journal of Energy Chemistry2021，30，4： | 1 |

| 10 | Dynamic Changes of ORF1ab and N Gene Ct Values in COVID-19 Omicron Inpatients of Different Age Groups—Beijing Municipality,China,November-December 2022显示文摘Introduction:In November 2021,the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)Omicron variant was identified as the variant of concern and has since spread globally,replacing other cocirculating variants.To better understand the dynamic changes in viral load over time and the natural history of the virus infection,we analyzed the expression of the open reading frames 1ab(ORF1ab)and nucleocapsid(N)genes in patients infected with Omicron.Methods:We included patients initially admitted to the hospital for SARS-CoV-2 infection between November 5 and December 25,2022.We collected daily oropharyngeal swabs for quantitative reverse transcriptase-polymerase chain reaction tests using commercial kits.We depicted the cycle threshold(Ct)values for amplification of ORF1ab and N genes from individual patients in age-specific groups in a time series.Results:A total of 480 inpatients were included in the study,with a median age of 59 years(interquartile range,42 to 78;range,16 to 106).In the<45-year-old age group,the Ct values for ORF1ab and N gene amplification remained below 35 for 9.0 and 11.5 days,respectively.In the≥80-year-old age group,the Ct values for ORF1ab and N genes stayed below 35 for 11.5 and 15.0 days,respectively,which was the longest among all age groups.The Ct values for N gene amplification took longer to rise above 35 than those for ORF1ab gene amplification.Conclusion:The time to test negative varied among different age groups,with viral nucleic acid shedding taking longer in older age groups compared to younger age groups.As a result,the time to resolution of Omicron infection increased with increasing age. | Qing Zhang Zhaomin Feng Yiwei Hao Lirong Wei Aibin Wang Zhixing Han Meimei Tian Sheng Sun Xin'gang Li Tianjiao Xue Xiangjing Kong Baoliang Li Cheng Kou Quanyi Wang Da Huo Linghang Wang | 2023 | China CDC weekly2023，5，8： | 0 |
| 11 | Late-stage azolation of benzylic C‒H bonds enabled by electrooxidation显示文摘The installation of azoles via C–H/N–H cross-coupling is significantly underdeveloped,particularly in benzylic C–H azolation due to the requirement for external chemical oxidants and the challenge in controlling the site-and chemo-selectivity.Herein,a late-stage azolation of benzylic C‒H bonds enabled by electrooxidation is described,which proceeds in an undivided cell under mild,catalyst-and chemical-oxidant-free reaction conditions.The strategy empowers the C‒H azolation on primary,secondary,and even challenging tertiary benzylic positions selectively.The remarkable synthetic utility of our approach is highlighted by its easy scalability without overoxidation of products and ample scope with valuable functional groups.The approach can be directly used to install benzyl and azole motifs on highly functionalized drug molecules. | Zhixiong Ruan Zhixing Huang Zhongnan Xu Shaogao Zeng Pengju Feng Ping-Hua Sun | 2021 | Science China Chemistry2021，64，5： | 0 |
| 12 | Direct Electrochemical Synthesis of Sulfur-Containing Triazolium Inner Salts显示文摘Main observation and conclusion The electrochemical thiocyanation/cyclization of aldehyde hydrazones was developed under external oxidant-free and catalyst-free conditions.In contrast to previous thiocyanation,this electrosynthetic approach enabled a cascade C-H thiocyanation/cyclization through a mild,direct electrolysis manner in an undivided cell without the additive of halogens and stoichiometric oxidants.In this protocol,commercially available and inexpensive sodium thiocyanate was used,which played a dual role as a thiocyanation reagent and electrolyte.This strategy provides expedient access to functionalized sulfur-containing triazolium inner salts with ample scope and diverse functional group tolerance.Based on the findings of mechanistic studies,a reaction mechanism was proposed. | Yueheng Li Zhixing Huang Guangquan Mo Wei Jiang Chengwei Zheng Pengju Feng Zhixiong Ruan | 2021 | Chinese Journal of Chemistry2021，39，4： | 0 |

| 14 | Static analysis of tympanic membrane in aero-otitis media by three-dimensional model of the middle ear显示文摘The three-dimensional(3D)model of the middle ear is of great significance to the research of middle ear related diseases.The particular focus of this work is to simulate the impact of aircraft altitude and speed changes on the tympanic membrane(TM)during the descent phase,so as to analyze the pathogenesis of aero-otitis media and the mechanical response characteristics of TM under static pressure.The simulations showed that the stress and strain of TM increase as the altitude difference and speed of the aircraft increase,and the maximum stress and strain areas are consistent with the clinical observation of TM hyperemia.Therefore,among many prevention and treatment measures of aero-otitis media,it is a therapeutic method to directly balance the pressure difference between the inner and outer TM. | Kaili Sun Xu Bie Zhixing Feng Shen Yu Xiuzhen Sun Jizhe Wang Yingxi Liu Lina Peng Zhaoxu Yao | 2022 | Theoretical & Applied Mechanics Letters2022，12，2： | 0 |
| 15 | A Hyper-Heuristic Framework for Lifetime Maximization in Wireless Sensor Networks With A Mobile Sink显示文摘Maximizing the lifetime of wireless sensor networks(WSNs) is an important and challenging research problem. Properly scheduling the movements of mobile sinks to balance the energy consumption of wireless sensor network is one of the most effective approaches to prolong the lifetime of wireless sensor networks. However, the existing mobile sink scheduling methods either require a great amount of computational time or lack effectiveness in finding high-quality scheduling solutions. To address the above issues, this paper proposes a novel hyperheuristic framework, which can automatically construct high-level heuristics to schedule the sink movements and prolong the network lifetime. In the proposed framework, a set of low-level heuristics are defined as building blocks to construct high-level heuristics and a set of random networks with different features are designed for training. Further, a genetic programming algorithm is adopted to automatically evolve promising high-level heuristics based on the building blocks and the training networks. By using the genetic programming to evolve more effective heuristics and applying these heuristics in a greedy scheme, our proposed hyper-heuristic framework can prolong the network lifetime competitively with other methods, with small time consumption. A series of comprehensive experiments, including both static and dynamic networks,are designed. The simulation results have demonstrated that the proposed method can offer a very promising performance in terms of network lifetime and response time. | Jinghui Zhong Zhixing Huang Liang Feng Wan Du Ying Li | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，1： | 0 |
| 16 | Water-resistant conductive organogels with sensation and actuation functions for artificial neuro-sensory muscular systems显示文摘The development of functional flexible conductive materials can significantly contribute to the improvement of intelligent human–computer integration.However,it is a challenge to endow human–machine interface with perception and response actuation simultaneously.Herein,a customizable and multifunctional electronic conductive organogel is proposed by combining conductive carbon nanotube(CNT)clusters and flexible adhesive organogels.The conductive CNT cluster layers generated on the surface of organogels equip the resulting organogel-based conductors with considerable quasi-superhydrophobicity and increase their potential applicability as highly sensitive stress and strain sensors.In particular,this quasi-superhydrophobicity is insensitive to tensile strain.Based on customizable conductive networks and entropy-driven organogel actuation,the conductive organogels can sense various strain and stress signals and imitate natural organisms with muscle actuation and neurofeedback.This strategy for preparing electronic conductors can enhance the rational design of soft robotics and artificial intelligence devices,facilitating further progress of human-like intelligent systems. | Zhixing Zhang Yunfei Yu Huitao Yu Yiyu Feng Wei Feng | 2022 | SmartMat2022，3，4： | 0 |
