| 1 | Formation mechanism of in-situ volcanic reservoirs in eastern China:A case study from Xushen gasfield in Songliao Basin显示文摘A large number of in-situ volcanic reservoirs have been discovered from the Meso-Cenozoic rift basin group in eastern China.Based on drilling results in combination with geological and geophysical analysis,a case study from the Early Cretaceous Xujiaweizi fault-depression shows that the formation mechanism of in-situ volcanic reservoirs is characterized by'fault-controlled body,body-controlled facies,facies-controlled reservoir,and reservoir-controlled accumulation'.In other words,deep faults control the volcanic eruption type,volcanic body,and gas reservoir distribution;the volcanic body determines the spatial distribution of volcanic facies and volcanic gas reservoir size;the volcanic facies control reservoir physical properties and effective thickness of gas formation;the volcanic reservoir properties control gas reservoir type and gas productivity.The result is useful to guiding the discovery of in-situ volcanic gas reservoirs in faulted basins in both theory and practice. | FENG ZiHui YIN ChangHai LIU JiaJun ZHU YingKang LU JiaMin LI JiangHai | 2014 | Science China Earth Sciences2014，57，12： | 12 |
| 2 | A deep seismic sounding profile across the Tianshan Mountains显示文摘The deep seismic sounding profile across the Tianshan Mountains revealed a two-layer crustal structure in the Tianshan region, namely the lower and upper crusts. Lateral variations of layer velocity and thickness are evidently shown. Low-velocity layers spread discontinuously at the bottom of the upper crust. The Mono depth is 47 km in the Kuytun area and 50 km in the Xayar area. In the Tianshan Mountains, the Moho becomes deeper with the maximum depth of 62 km around the boundary between the southern and northern Tianshan Mountains. The average velocity ranges from 6.1 to 6.3 km/s in the crust and 8.15 km/s at the top of the upper mantle. Two groups of reliable reflective seismic phases of the Moho (Pm1 and Pm2) are recognized on the shot record section of the Kuytun area. A staked and offset region, 20-30 km long, is displayed within a shot-geophone distance of 190-210 km in Pm1 and Pm2. Calculation shows that the Moho is offset by 10 km in the northern Tianshan region, 62 km deep in the south while | LU Deyuan LI Qiusheng GAO Rui LI Yingkang LI Dexing LIU Wen ZHANG Zhiying | 2000 | Chinese Science Bulletin2000，45，22： | 9 |

| 6 | In-situ fabrication of carbon compound NiFeMo-P anchored on nickel foam as bi-functional catalyst for boosting overall water splitting显示文摘The efficient non-noble metal-based bifunctional electrocatalyst for hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)has attracted great interest,which is highly significant to enhance the efficiency of hydrogen production from water electrolysis.Herein,inspired by the appropriate hydrogen adsorption free energy of transition metal alloy and the strong corrosion resistance of phosphide in alkaline electrolyte,carbon compound NiFeMo-P anchored on nickel foam(NiFeMo-P-C)is obtained by simple one-pot hydrothermal and subsequent hydrogen reduction treatment.Remarkably,the NiFeMo-P-C exhibits excellent bifunctional electrocatalytic performances toward HER and OER with low overpotentials of 87 and 196 mV at 10 mA·cm^(-2),respectively.Moreover,the electrolyzer using NiFeMo-P-C as both cathode and anode only requires a cell voltage of 1.50 V to reach a current density of 10 mA·cm^(-2),along with an outstanding long-term stability for 50 h.The synergistic effect among alloys and phosphide,partially broken hollow morphology and porous nickel foam substrate jointly impart NiFeMo-P-C high electrocatalytic activity and superior durability. | Xiangyang Zhou Tingting Yang Ting Li Youju Zi Sijing Zhang Lei Yang Yingkang Liu Juan Yang Jingjing Tang | 2023 | Nano Research Energy2023，2，4： | 0 |
| 7 | Successful clearance of persistent SARS-CoV-2 asymptomatic infection following a single dose of Ad5-nCoV vaccine显示文摘Persistent asymptomatic(PA)SARS-CoV-2 infections have been identified.The immune responses in these patients are unclear,and the development of effective treatments for these patients is needed.Here,we report a cohort of 23 PA cases carrying viral RNA for up to 191 days.PA cases displayed low levels of inflammatory and interferon response,weak antibody response,diminished circulating follicular helper T cells(cTfh),and inadequate specific CD4+and CD8+T-cell responses during infection,which is distinct from symptomatic infections and resembling impaired immune activation.Administration of a single dose of Ad5-nCoV vaccine to 10 of these PA cases elicited rapid and robust antibody responses as well as coordinated B-cell and cTfh responses,resulting in successful viral clearance.Vaccine-induced antibodies were able to neutralize various variants of concern and persisted for over 6 months,indicating long-term protection.Therefore,our study provides an insight into the immune status of PA infections and highlights vaccination as a potential treatment for prolonged SARS-CoV-2 infections. | Shaofu Qiu Zhao Chen Airu Zhu Qiuhui Zeng Hongbo Liu Xiaoqing Liu Feng Ye Yingkang Jin Jie Wu Chaojie Yang Qi Wang Fangli Chen Lan Chen Sai Tian Xinying Du Qingtao Hu Jinling Cheng Canjie Chen Fang Li Jing Sun Yanqun Wang Jingxian Zhao Jincun Zhao Hongbin Song | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 0 |
| 8 | Tight gas charging and accumulation mechanisms and mathematical model显示文摘The gas-water distribution and production heterogeneity of tight gas reservoirs have been summarized from experimental and geological observations, but the charging and accumulation mechanisms have not been examined quantitatively by mathematical model. The tight gas charging and accumulation mechanisms were revealed from a combination of physical simulation of nuclear magnetic resonance coupling displacement, numerical simulation considering material and mechanical equilibria, as well as actual geological observation. The results show that gas migrates into tight rocks to preferentially form a gas saturation stabilization zone near the source-reservoir interface. When the gas source is insufficient, gas saturation reduction zone and uncharged zone are formed in sequence from the source-reservoir interface. The better the source rock conditions with more gas expulsion volume and higher overpressure, the thicker the gas saturation stabilization and reduction zones, and the higher the overall gas saturation. When the source rock conditions are limited, the better the tight reservoir conditions with higher porosity and permeability as well as larger pore throat, the thinner the gas saturation stabilization and reduction zones, but the gas saturation is high. The sweet spot of tight gas is developed in the high-quality reservoir near the source rock, which often corresponds to the gas saturation stabilization zone. The numerical simulation results by mathematical model agree well with the physical simulation results by nuclear magnetic resonance coupling displacement, and reasonably explain the gas-water distribution and production pattern of deep reservoirs in the Xujiaweizi fault depression of the Songliao Basin and tight gas reservoirs in the Linxing-Huangfu area of the Ordos Basin. | ZHOU Nengwu LU Shuangfang ZHANG Pengfei LIN Zizhi XIAO Dianshi LU Jiamin ZHU Yingkang LIU Yancheng LIN Liming WANG Min JIANG Xinyu LIU Yang WANG Ziyi LI Wenbiao | 2023 | Petroleum Exploration and Development2023，50，6： | 0 |
