| 1 | Biogas charging and dissipating process and its accumulation in the Sebei gasfield,Qaidam Basin,China显示文摘The Sebei gasfield is the largest biogas accumulation found in China and many reservoirs and seal rocks superposed on a syndepositional anticline in Quaternary.The biogas charging and dissipating process and its distribution have been a research focus for many years.The authors suggest a diffusing and accumulating model for the biogas,as they find that the shallower the gas producer,the more methane in the biogas,and the lighter stable carbon isotope composition of methane.Based on the diffusing model,diffused biogas is quantitatively estimated for each potential sandy reservoir in the gasfield,and the gas charging quantity for the sandy reservoir is also calculated by the diffused gas quantity plus gas reserve in-place.A ratio of diffusing quantity to charging quantity is postulated to describe biogas accumulating state in a sandy reservoir,if the ratio is less than 0.6,the reservoir forms a good gas-pool and high-production layer in the gasfield,which often occurs in the reservoirs deeper than 900 m;if the ratio is greater than 0.6,a few gas accumulated in the reservoir,which frequently exists in the reservoirs shallower than 900 m.Therefore,a biogas accumulation model is built up as lateral direct charging from gas source for the sands deeper than 900 m and indirect charging from lower gas-bearing sands by diffusion at depth shallower than 900 m.With this charging and diffusion quantitative model,the authors conducted re-evaluation on each wildcat in the central area of the Qaidam Basin,and found many commercial biogas layers. | JIN Qiang 1,CHENG FuQi 1,2 ,SU AiGuo 3 ,ZHU GuangYou 3 ,WANG Li 1 &CAO Qian 1 1 China University of Petroleum,Dongying,Shandong 257061,China 2 Geological Institute of Shengli Oilfield,SINOPEC,Dongying,Shandong 257015,China 3 Petroleum Exploration and Development Institute,PetroChina,Beijing 100083,China | 2008 | Science China Earth Sciences2008，51，S1： | 2 |
| 2 | Discriminating hydrocarbon generation potential of coaly source rocks and their contribution:a case study from the Upper Paleozoic of Bohai Bay Basin,China显示文摘Although various coaly source rocks widely developed in the Carboniferous-Permian(C-P)of the Bohai Bay Basin,their geochemical characteristics and hydrocarbon generation potential are poorly understood.This study aims to discriminate the contribution of hydrocarbon generation from different C-P coaly source rocks and clarify the differences within generated oils using organic geochemistry,organic petrology,and thermal simulation experiments.The coaly source rocks containt coal clarain and durain,carbonaceous shale,and shale deposited in deltaic and lagoonal environment.The results indicated that clarain,durain,and carbonaceous shale exhibited higher hydrogen index and liquid-gas hydrocarbon yields than lagoonal and deltaic shales,which was mainly associated with the concentrations of sporinite,cutinite,and hydrogen-rich collodetrinite.Aliphatic hydro-carbons originated firom coal and carbonaceous shale presented lower Ts/(Ts+Tm),Ga/17α(H)21β(H)-C_(30)hopane,18α(H)-oleanane/17α(H)21β(H)-C_(30)hopane ratios,and higher 17β3(H)21α(H)-C_(30)Morane/17α(H)21β(H)-C_(30)hopane than deltaic lagoonal shales.Parameters of aromatic hydrocarbons generated from five lithologies of coaly source rocks trended as clear group distribution,e.g.,clarain and durain showing lower MNR,DBT/Fluorene(F)ratios and higher DBF/F ratio than coaly shales.The distinct descending trend of hydrocarbon potential is obtained from clarain,durain,carbonaceous shale to lagoonal and deltaic shales,implying dominated the petroleum and natural gas supplement from coal and carbonaceous shale.The difference between aliphatic and aromatic hydrocarbons provides a significant contribution to analyze the generic relationship between coaly source rock and lacustrine shale.Our results illustrate the importance of coaly source rocks for the in-depth oil-gas exploration of the Bohai Bay Basin and understanding hydrocarbon generation potential of source rocks in coal bearing strata. | Jinjun XU Da LOU Qiang JIN Lixin FU Fuqi CHENG Shuhui ZHOU Xiuhong WANG Chao LIANG Fulai LI | 2021 | Frontiers of Earth Science2021，15，4： | 1 |

| 5 | Synergy of first-and second-sphere interactions in a covalent organic framework boosts highly selective platinum uptake显示文摘Platinum recovery from waste electrical and electronic equipment(WEEE) in highly acidic solutions is significant to the electronics industry and environmental remediation. However, the lack of ingenious design and synergetic coordination gives rise to unsatisfied PtCl_(4)^(2-)extraction capacities and selectivities in most previously reported adsorbents(e.g., polymeric and inorganic materials). Herein, we proposed a synergistic strategy that realizes highly selective PtCl_(4)^(2-)uptake through first-and second-sphere coordinations. The proof-of-concept imine-linked covalent organic framework(SCU-COF-3) was found to chelate Pt Cl42-via the direct N…Pt coordination and the synergistically interlaminar N–H…Cl hydrogen bonds, which was disclosed by the comprehensive analysis of extended X-ray adsorption fine structure(EXAFS) characterizations and density functional theory(DFT) calculations. The unique adsorption mechanism imparts a superior adsorption capacity(168.4 mg g-1)and extraordinary Pt(II) selectivity to SCU-COF-3 under static conditions. In addition, SCU-COF-3 exhibits an upgraded distribution coefficient of 1.62 × 10^(5)mL· g^(-1), one order of magnitude higher than those of reported natural adsorbents. Specifically, SCU-COF-3 can extract PtCl_(4)^(2- )quantitatively from a simulated acidic waste solution coexisting with other 12 competitive ions, suggesting its promising application in practical scenarios. | Linwei He Baoyu Li Zhonglin Ma Lixi Chen Shicheng Gong Mingxing Zhang Yaoyao Bai Qi Guo Fuqi Wu Fuqiang Zhao Jie Li Duo Zhang Daopeng Sheng Xing Dai Long Chen Jie Shu Zhifang Chai Shuao Wang | 2023 | Science China Chemistry2023，66，3： | 0 |
| 6 | Superior Iodine Uptake Capacity Enabled by an Open Metal-Sulfide Framework Composed of Three Types of Active Sites显示文摘Efficient adsorption of gaseous radioiodine is pivotal for the sustainable development of nuclear energy and the long-termradiation safety of the ecological system.However,state-of-the-art adsorbents(e.g.metal-organic frameworks and covalent-organic frameworks)currently under exploration suffer severely from limited adsorption capacity,especially under a real-world scenariowith extremely lowradioiodine concentration and elevated temperature.This mostly originates from the relatively weak sorption driving forces mainly determinedby the iodine-adsorbent interaction consistingof noncovalent interactionswith a small fraction of strong chemical bonding.Here,we document the discovery of an open metal-sulfide framework((NH_(4))_(2)(Sn_(3)S_(7)),donated as SCU-SnS)constructed by three different types of active sites as a superior iodine adsorbent.Benefiting from the ability of iodine for pre-enrichment into the framework by charge-balancing NH_(4)^(+)through N-H···I interaction,the efficient reduction of I^(2)affording I^(-)by S^(2-),and extremely high binding affinity between Sn_(4)^(+)and I^(-),SCU-SnS exhibit a record-breaking iodine adsorption capacity(2.12 g/g)under dynamic breakthrough conditions and the highest static capacity(6.12 g/g)among all reported inorganic adsorbents,both at 348 K.Its facile synthesis and low cost endow SCU-SnS with powerful application potential for the nuclear industry. | Yugang Zhang Linwei He Tingting Pan Jian Xie Fuqi Wu Xinglong Dong Xia Wang Lixi Chen Shicheng Gong Wei Liu Litao Kang Junchang Chen Lanhua Chen Long Chen Yu Han Shuao Wang | 2023 | CCS Chemistry2023，5，7： | 0 |
| 7 | A review: effect and mechanism of plant extracts rich in polyphenols on reducing uric acid activity显示文摘Hyperuricemia is a metabolic condition caused by the increase of uric acid level in the body,which can lead to gout,kidney disease,cardiovascular disease,hypertension and diabetes.In recent years,the incidence rate of hyperuricemia has been increasing and gradually becoming younger.Allopurinol and febuxostat are commonly used drugs to reduce the level of uric acid in the body.Although these drugs have good curative effect,they can produce adverse reactions.Therefore,it has been the focus of attention to find appropriate treatment and new drugs to reduce serum uric acid level.Natural plants have become the source of new drugs for their multiple biological activities,strong efficacy and minimal side effects.More and more studies have shown that natural plant extracts rich in phenols,flavonoids and other active components can significantly reduce the level of uric acid,and improve the complications caused by high uric acid.In this paper,hyperuricemia related diseases,functional plants rich in polyphenols with the effect of reducing uric acid and the mechanism of their active components were reviewed. | Shuping Wang Fuqi Wang Ruowen Zhang Xu Zhao | 2021 | Journal of Polyphenols2021，3，1： | 0 |
| 8 | A Statistical Algorithm for Retrieving Background Value of Absorbing Aerosol Index Based on TROPOMI Measurements显示文摘The ultraviolet aerosol index(UVAI) is essential for monitoring the absorbing aerosols during aerosol events. UVAI depends on the absorbing aerosol concentration, the viewing geometry, and the temporal drift of radiometric sensitivity. To efficiently detect absorbing aerosols with the highest precision and to improve the accuracy of long-term UVAI estimates,the background UVAI must be examined through the UVAI retrieval. This study presents a statistical method that calculates the background value of UVAI using TROPOspheric Monitoring Instrument(TROPOMI) observation data over the Pacific Ocean under clear-sky scenes. Radiative transfer calculations were performed to simulate the dependence of UVAI on aerosol type and viewing geometry. We firstly applied the background UVAI to reducing the effects of viewing geometry and the degradation of the TROPOMI irradiance measurements on the UVAI. The temporal variability of the background UVAI under the same viewing geometry and aerosol concentration was identified. Radiative transfer calculations were performed to study the changes in background UVAI using Aerosol Optical Depth from the Moderate Resolution Imaging Spectroradiometer(MODIS) and reflectance measurements from TROPOMI as input. The trends of the temporal variations in the background UVAI agreed with the simulations. Alterations in the background UVAI expressed the reflectance variations driven by the changes in satellite state. Decreasing trends in solar irradiance at 340 and 380 nm due to instrument degradation were identified. Our findings are valuable because they can be applied to future retrievals of UVAI from the Environmental Trace Gases Monitoring Instrument(EMI) onboard the Chinese GaoFen-5 satellite. | Fuying TANG Weihe WANG Fuqi SI Haijin ZHOU Yuhan LUO Dongshang YANG Yuanyuan QIAN | 2023 | Advances in Atmospheric Sciences2023，40，6： | 0 |
| 9 | Identification of Key Links in Electric Power Operation Based-Spatiotemporal Mixing Convolution Neural Network显示文摘As the scale of the power system continues to expand,the environment for power operations becomes more and more complex.Existing risk management and control methods for power operations can only set the same risk detection standard and conduct the risk detection for any scenario indiscriminately.Therefore,more reliable and accurate security control methods are urgently needed.In order to improve the accuracy and reliability of the operation risk management and control method,this paper proposes a method for identifying the key links in the whole process of electric power operation based on the spatiotemporal hybrid convolutional neural network.To provide early warning and control of targeted risks,first,the video stream is framed adaptively according to the pixel changes in the video stream.Then,the optimized MobileNet is used to extract the feature map of the video stream,which contains both time-series and static spatial scene information.The feature maps are combined and non-linearly mapped to realize the identification of dynamic operating scenes.Finally,training samples and test samples are produced by using the whole process image of a power company in Xinjiang as a case study,and the proposed algorithm is compared with the unimproved MobileNet.The experimental results demonstrated that the method proposed in this paper can accurately identify the type and start and end time of each operation link in the whole process of electric power operation,and has good real-time performance.The average accuracy of the algorithm can reach 87.8%,and the frame rate is 61 frames/s,which is of great significance for improving the reliability and accuracy of security control methods. | Lei Feng Bo Wang Fuqi Ma Hengrui Ma Mohamed AMohamed | 2023 | Computer Systems Science & Engineering2023，46，8： | 0 |
| 10 | State Evaluation Based on Feature Identification of Measurement Data:for Resilient Power System显示文摘Resilient power systems urgently need real-time evaluation of their operational states.By mining the characteristics of the grid operational data and mapping them to the operational state,this paper proposes a method to evaluate the real-time state and the evolution direction of power systems.First,the state evaluation matrix is constructed using nodal voltages.Then,from the data-driven perspective,the grid state is embodied in the operational data change.Furthermore,four indicators are proposed to characterize the power grid statefrom inherent physical and operating characteristics perspectives.Finally,through the simulations of a real power grid in China,it is shown that the method proposed in this paper can adequately characterize the power grid state,and is robust against bad data. | Hongxia Wang Bo Wang Peng Luo Fuqi Ma Yinyu Zhou Mohamed A.Mohamed | 2022 | CSEE Journal of Power and Energy Systems2022，8，4： | 0 |
| 11 | Skeleton-based Violation Action Recognition Method for Safety Supervision in Operation Field of Distribution Network Based on Graph Convolutional Network显示文摘Safety accidents in the operation field of the distribution network often occur,which seriously endanger the safety and lives of operators.Existing identification methods for safety risk can identify static safety risks,such as no-helmet,no-safety gloves,etc.,but fail to identify risks in the dynamic actions of operators.Therefore,this paper proposes a skeletonbased violation action-recognition method for supervision of safety during operations in a distribution network,i.e.,based on spatial temporal graph convolutional network(STGCN)and key joint attention module(KJAM),which can implement dynamic violation behavior recognition of operators.In this method,the human posture estimation method,i.e.Multi-Person Pose Estimation,is utilized to extract the skeleton information of operators during operations,and to construct an undirected graph,which reflects the movement and posture of the human body.Then,the STGCN is utilized to identify actions of operators that can lead to dynamic violations.In addition,the KJAM captures important joint information of operators.The effectiveness and superiority of the proposed method are verified in comparison to other action recognition methods.The experimental results show that the proposed method has higher recognition accuracy for common violations collected at the actual operation site of the distribution network and shows a strong generalization ability,which can be applied to the video monitoring system of field operations to reduce the occurrence of safety accidents. | Bo Wang Fuqi Ma Rong Jia Peng Luo Xuzhu Dong | 2023 | CSEE Journal of Power and Energy Systems2023，9，6： | 0 |
| 12 | Galangin probably ameliorates hyperuricemia by inhibiting urate acid transport 1 (URAT1): Homology modeling and mechanism exploration显示文摘Urate acid transporter 1(URAT1)is the main transporter of uric acid reabsorption,which closely related to the pathogenesis of hyperuricemia.Screening URAT1 inhibitors and studying their possible metabolic processes is a hot spot in the development of uric acid-lowering drugs.Studies have shown that many food-borne plant polyphenols have uric acid lowering activity with non-toxic side eff ects,and can be used to improve and alleviate hyperuricemia.In this study,we take galangin(GAL)as an example to explore the mechanism of plant polyphenols aff ecting hyperuricemia by inhibiting URAT1.Homology modeling was used to construct a three-dimensional model of URAT1 protein,and the structure was optimized.Ramachandran diagram was used to verify the rationality of model protein structure.A known URAT1 inhibitor,benzbromarone(BBR),was used to dock with URAT1 to determine the docking site and show the key amino acids.GAL and model protein were docked by molecular docking method to analyze their interaction.Meanwhile,comparing the interaction of BBR and GAL with the key amino acids of model proteins,the binding of GAL was more stable,suggesting that GAL could aff ects hyperuricemia by inhibiting URAT1.This paper aims to provide theoretical guidance for the development of new functional food ingredients for lowering uric acid. | Aijinxiu Ma Fuqi Wang Xu Zhao | 2022 | Journal of Polyphenols2022，4，1： | 0 |
