| 1 | Cobalt single atom site catalysts with ultrahigh metal loading for enhanced aerobic oxidation of ethylbenzene显示文摘The oxidation of hydrocarbons to produce high value-added compounds(ketones or alcohols)using oxygen in air as the only oxidant is an efficient synthetic strategy from both environmental and economic views.Herein,we successfully synthesized cobalt single atom site catalysts(Co SACs)with high metal loading of 23.58 wt.%supported on carbon nitride(CN),which showed excellent catalytic properties for oxidation of ethylbenzene in air.Moreover,Co SACs show a much higher turn-over frequency(19.6 h^(−1))than other reported non-noble catalysts under the same condition.Comparatively,the as-obtained nanosized or homogenous Co catalysts are inert to this reaction.Co SACs also exhibit high selectivity(97%)and stability(unchanged after five runs)in this reaction.DFT calculations reveal that Co SACs show a low energy barrier in the first elementary step and a high resistance to water,which result in the robust catalytic performance for this reaction. | Yu Xiong Wenming Sun Yunhu Han Pingyu Xin Xusheng Zheng Wensheng Yan Juncai Dong Jian Zhang Dingsheng Wang Yadong Li | 2021 | Nano Research2021，14，7： | 20 |

| 4 | Research on HJ-1A/B satellite data automatic geometric precision correction design显示文摘Developed independently by China,HJ-1A/B satellites have operated well on-orbit for five years and acquired a large number of high-quality observation data.The realization of the observation data geometric precision correction is of great significance for macro and dynamic ecological environment monitoring.The paper analyzed the parameter characteristics of HJ-1 satellite and geometric features of HJ-1 satellite level 2 data(systematic geo- corrected data).Based on this,the overall HJ- 1 multi- sensor geometric correction flow and charge-coupled device(CCD) automatic geometric precision correction method were designed.Actual operating data showed that the method could achieve good result for automatic geometric precision correction of HJ-1 satellite data,automatic HJ-1 CCD image geometric precision correction accuracy could be achieved within two pixels and automatic matching accuracy between the images of same satellite could be obtained less than one pixel. | Xiong Wencheng Shen Wenming Wang Qiao Shi Yuanli Xiao Rulin Fu Zhuo | 2014 | Engineering Sciences2014，12，5： | 0 |

| 6 | Interfacial friction at action: Interactions, regulation, and applications显示文摘Friction is a fundamental force that impacts almost all interface-related applications.Over the past decade,there is a revival in our basic understanding and practical applications of the friction.In this review,we discuss the recent progress on solid–liquid interfacial friction from the perspective of interfaces.We first discuss the fundamentals and theoretical evolution of solid–liquid interfacial friction based on both bulk interactions and molecular interactions.Then,we summarize the interfacial friction regulation strategies manifested in both natural surfaces and artificial systems,focusing on how liquid,solid,gas,and hydrodynamic coupling actions mediate interfacial friction.Next,we discuss some practical applications that are inhibited or reinforced by interfacial friction.At last,we present the challenges to further understand and regulate interfacial friction. | Zhiran YI Xiong WANG Wanbo LI Xuezhi QIN Yang LI Kaiqiang WANG Yunting GUO Xing LI Wenming ZHANG Zuankai WANG | 2023 | Friction2023，11，12： | 0 |

| 8 | Organic Geochemical Characteristics of Source Rocks of Hongshuizhuang Formation in the Mengjiawopu Section of Lingyuan-Ningcheng Basin in North China显示文摘Through the regional geological survey,outcrop section measurement and other field geological work,a block of black shale is found at the outcrop of Mengjiawopu Section of Hongshuizhuang Formation in Jixian County,and organic geochemical source rock analysis and evaluation methods are used to study the source rocks in Hongshuizhuang Formation.The set of source rocks is mainly gray-black silty mudstone and gray-black shale,with a cumulative thickness of 78 m;the total organic matter(TOC)is generally high,with an average content of 1.35%,of which good and rich source rock samples account for 86%.A combined analysis of the stable carbon isotope of kerogen,the correlation between Pr/nC17 and Ph/nC18,and the ratio of saturated hydrocarbon to aromatic hydrocarbon identifies that the organic matter is mainly TypeⅡkerogen;the equivalent vitrinite reflectance R o of organic matter is from 1.68%to 1.94%.R c,the correlation of the methylphenanthrene index(MPI)against the vitrinite reflectance is from 1.63%to 1.81%,with an average of 1.71%,and the Odd/Even Predominance(OEP)value is between 0.87 and 1.11,both indicating that the source rocks of the Hongshuizhuang Formation are at the stage of high to over maturation.In summary,the set of source rocks in Hongshuizhuang Formation is characterized by high organic matter content,good kerogen types,and high to over maturation stage. | Quan Xiong Youjun Tang Wenming Zong Shouliang Sun Daxiang He Feng Wang | 2019 | Open Journal of Yangtze Oil and Gas2019，4，3： | 0 |
| 9 | Transformation and immobilization of hexavalent chromium in the co-presence of biochar and organic acids:effects of biochar dose and reaction time显示文摘A batch experiment was conducted to examine the effects of biochar dose and reaction duration on the transformation and immobilization of Cr(VI)in the combined biochar and low-molecular-weight organic acid systems.The results showed that increase in the dosage level of biochar caused increase in the solution pH,particularly for the Biochar300 treatments but did not enhance the reduction of Cr(VI)after 1-day reaction.Over 35%of the converted Cr(III)was immobilized by sorption to the biochar due to increased negatively charged sites on the biochar surfaces driven by pH rise.The elevated pH due to biochar dose increase tended to slow down the reduction of Cr(VI)to Cr(III),resulting in more Cr(VI)being adsorbed at a higher biochar dose.For the higher-temperature biochars,the increase in biochar dose did not markedly change the transformation and immobilization of the added Cr.Increase in the reaction duration markedly increased the pH for Biochar300.This resulted in the disappearance of all Cr(VI)in the solution after the 7-day reaction,possibly through sorption of cationic Cr(III)to the biochar surfaces.Increase in reaction time for the higher-temperature biochars resulted in re-oxidation of Cr(III)to Cr(VI)due to the increased exposure of solution Cr(III)to atmospheric oxygen.The research findings obtained from this study have implications for optimizing treatment procedure for wastewater that contains elevated level of toxic Cr(VI).Simulation experiments are required to determine appropriate biochar dose and reaction time to achieve cost-effective treatment goals. | Yongjun Li Wenming Xiong Xin Wei Junhao Qin Chuxia Lin | 2021 | Biochar2021，3，4： | 0 |
