| 1 | Geological and Geochemical Characteristics and Exploration Prospect of Coal-Derived Tight Sandstone Gas in China: Case Study of the Ordos, Sichuan, and Tarim Basins显示文摘This work extensively investigated global tight sandstone gas, and geologically and geochemically analyzed the tight sandstone gas in China's Ordos, Sichuan, and Tarim basins. We compared typical tight sandstone gas in China with that in North America. We proposed six conditions for the formation of China's tight sandstone gas, and illustrated the geological characteristics of tight sandstone gas. In China, gas-bearing tight sandstones were mainly deposited in continental lake deltas and marine-terrigenous facies basin environments, associated with coal-measure strata, and were mostly buried deeper than 2000 m under a formation pressure of 20–30 MPa, with pressure coefficients varying from overpressure to negative pressure. In other countries, tight gas bearing sandstones were dominantly deposited in marine to marine-terrigenous facies environments, occurred in coal-measure strata, and were mostly buried shallower than 2000 m in low-pressure systems. We systematically analyzed tight sandstone gas in the Ordos, Sichuan, and Tarim basins in terms of chemical compositions, geochemical characteristics of carbon isotopes, origins, and sources. Tight sandstone gas in China usually has a hydrocarbon content of >95%, with CH4 content >90%, and a generally higher dry coefficient. In the three above-mentioned large tight sandstone gas regions, δ13 C1 and δ13 C2 mainly ranges from-42‰ to-28‰ and from-28‰ to-21‰, respectively. Type III coal-measure source rocks that closely coexist with tight reservoirs are developed extensively in these gas regions. The organic petrology of source rocks and the carbon isotope compositions of gas indicate that tight sandstone gas in China is dominantly coal-derived gas generated by coal-measure strata. Our analysis of carbon isotope series shows that local isotope reversals are mainly caused by the mixing of gases of different maturities and that were generated at different stages. With increasing maturity, the reversal tendency becomes more apparent. Moreover, natural gas with medium-low maturity(e.g., Xujiahe Formation natural gas in the Sichuan Basin) presents an apparent reversal at a low-maturity stage, a normal series at a medium-maturity stage, and a reversal tendency again at a high-maturity stage. Finally, we proposed four conditions for preferred tight sandstone gas 'sweep spots,' and illustrated the recoverable reserves, proven reserves, production, and exploration prospects of tight sandstone gas. The geological and geochemical characteristics, origins, sources, and exploration potential of tight sandstone gas in China from our research will be instructive for the future evaluation, prediction, and exploration of tight sandstone gas in China and abroad. | ZOU Caineng TAO Shizhen HAN Wenxue ZHAO Zhenyu MA Weijiao LI Changwei BAI Bin GAO Xiaohui | 2018 | Acta Geologica Sinica(English Edition)2018，92，4： | 11 |
| 2 | Fabrication and oxidation resistance of silicon nitride fiber reinforced silica matrix wave-transparent composites显示文摘Wave-transparent ceramic matrix composites for the high temperature use should possess excellent oxidation resistance. In this work, Si3N4f/SiO2 composites with different fiber content were fabricated by filament winding and sol gel method. The oxidation resistance was investigated by tracking the response of flexural strength to the testing temperature. The results show that the flexural strength and toughness of the composites with fiber content of over 37% can reach high levels at around 175.0 MPa and 6.2 MPa m^1/2, respectively. After 1 h oxidation at 1100℃, the flexural strength drops a lot but can still reach 114.4 MPa, which is high enough to ensure the safety of structures. However, when the oxidation temperature rises to 1200–1400℃, the flexural strengths continue to fall to a relatively low level at 50.0–66.4 MPa. The degradation at high temperatures is caused by the combination of over strong interfacial bonding, the damage of fiber and the crystallization of silica matrix. | Xuejin Yang Bin Li Duan Li Changwei Shao Changrui Zhang Chunrong Zou Kun Liu | 2019 | Journal of Materials Science & Technology2019，35，12： | 4 |

| 8 | All-in-one phototheranostics based on BTP-4F-DMO nanoparticles for NIR-II fluorescence/photoacoustic dual-mode imaging and combinational therapy显示文摘Various phototheranostics have recently been developed for phototherapy.Through proper molecular design,the photochemical and photophysical properties of these phototheranostics can be promoted.Herein,an acceptor-donor-acceptor(A-D-A)-structured dye,BTP-4F-DMO,was synthesized and prepared into water-soluble nanoparticles(NPs).The obtained BTP-4F-DMO NPs had strong absorption from650 nm to 850 nm and a fluorescence emission peak at~900 nm that tailed to~1100 nm.The NPs showed a superhigh photothermal conversion efficiency of 90.5%±5%and could simultaneously generate·OH and^(1)O_(2)with a^(1)O_(2)generation quantum yield of 4.6%under 808 nm laser irradiation.Due to these advanced properties,BTP-4F-DMO NPs can switch the role of autophagy from pro-survival to prodeath,thereby further promoting cancer cell death.These features make BTP-4F-DMO NPs a promising multifunctional phototheranostic agent for NIR-II fluorescence/photoacoustic dual-mode imaging-guided synergetic photodynamic/photothermal therapy.In general,this work provides a strategy for expanding the biomedical applications of organic A-D-A-structured phototheranostics. | Ke Yang Bowen Yu Wei Liu Zequn Zhang Li Huang Shaojing Zhao Benhua Wang Jianing Yi Jun Yuan Yingping Zou Changwei Lin Xiangzhi Song Minhuan Lan | 2023 | Chinese Chemical Letters2023，34，6： | 0 |
