| 1 | Stable carbon and hydrogen isotopes of gases from the large tight gas fields in China显示文摘By the end of the year 2010,a total of 15 large tight gas fields have been found in China,located in the Ordos,Sichuan,and Tarim basins.The annual production and total reserves of these fields in 2010 were 222.5×108and 28657×108m3,respectively,accounting for 23.5%and 37.3%,respectively,of the total annual production and reserves of natural gases in China.They took a major part of all natural gas production and reserves in China.According to the analyses of 81 gas samples,the stable carbon and hydrogen isotopic compositions of tight gases in China have following characteristics:(1)Plots of 13C1-13C2-13C3,13C1-C1/C2+3and 13C1-13C2demonstrate the coal-derived origin of tight gases in China;(2)For the primary alkane gases,both carbon and hydrogen isotopic values increase with increasing molecular mass,i.e.,13C1<13C2<13C3<13C4and2H1<2H2<2H3;(3)The isotopic differences of 13C2-13C1,13C3-13C1,2H2-2H1and 2H3-2H1decrease with increasing Ro(%)and C1/C1–4;(4)There are seven causes for the carbon and hydrogen isotopic reversal,however,the carbon and hydrogen isotopic reversal of tight gases in China is caused mainly by multiple stages of gas charge and accumulation. | DAI JinXing NI YunYan HU GuoYi HUANG ShiPeng LIAO FengRong YU Cong GONG DeYu WU Wei | 2014 | Science China Earth Sciences2014，57，1： | 17 |

| 3 | Origin and source of CO_2 in natural gas from the eastern Sichuan Basin显示文摘The CO2 contents of natural gas from the eastern Sichuan Basin were mainly less than 2%,and they were generally large when the H2S contents were over 5%.The natural gas in the eastern Sichuan Basin showed high δ13C1 values uncorrelated with H2S contents,and the oil-associated gas generally displayed carbon isotopic reversal between methane and ethane,whereas the coal-derived gas samples displayed positive series.The δ13C values of CO2 in the natural gas could be divided into two types,one with low values(-24‰--12‰)and the other with high values(-8‰-4‰).The natural gas had low R/Ra values and broad CO2/3He values distinct from the mantle-derived gas,and the CO2 was typical of crustal origin.Natural gas with high δ13CCO2 values is distributed in the north region of the eastern Sichuan Basin,and CO2 in H2S-poor and H2S-free reservoirs was mainly derived from the thermal decomposition of carbonate rocks under Permian magmatism and high heat flow,whereas CO2 in the gas reservoirs with high TSR extent was derived mainly from the dedolomitization of carbonate reservoirs under acidic formation water,and the CO2 of TSR origin generally entered into the secondary calcite.The CO2 in natural gas in the south-central region of the eastern Sichuan Basin,which had been rarely affected by the Emeishan mantle plume,displayed low δ13C values and was of organic origin.Though the natural gas in Wolonghe gas field had experienced TSR,the low reaction extent and weak acidity of formation water could hardly have resulted in the dedolomitization,and therefore CO2 in the natural gas was mainly of TSR origin with low δ13C values. | WU XiaoQi DAI JinXing LIAO FengRong HUANG ShiPeng | 2013 | Science China Earth Sciences2013，56，8： | 3 |
| 4 | Transparent,stretchable,temperature-stable and self-healing ionogel-based triboelectric nanogenerator for biomechanical energy collection显示文摘A flexible and stable power supply is essential to the rapid development of wearable electronic devices.In this work,a transparent,flexible,temperature-stable and ionogel electrode-based self-healing triboelectric nanogenerator(IS-TENG)was developed.The ionogel with excellent stretchability(1,012%),high ionic conductivity(0.3 S·m^(−1))and high-temperature stability(temperature range of−77 to 250℃)was used as the electrode of the IS-TENG.The IS-TENG exhibited excellent transparency(92.1%)and stability.The output performance did not decrease when placed in a 60℃oven for 48 h.In addition,the IS-TENG behaved like a stable output in the range of−20 to 60℃.More importantly,the IS-TENG could also achieve self-healing of electrical performance at temperatures between−20 and 60℃and its output can be restored to its original state after healing.When the single-electrode IS-TENG with an area of 3 cm×3 cm was conducted under the working frequency of 1.5 Hz,the output values for open-circuit voltage,short-circuit current,short-circuit transferred charge,and maximum peak power density were 189 V,6.2μA,57 nC,and 2.17 W·m^(−2),respectively.The IS-TENG enables to harvest biomechanical energy,and drive electronic devices.Furthermore,the application of IS-TENGs as self-driven sensors for detecting human behavior was also demonstrated,showing good application prospects in the field of wearable power technology and self-driven sensing. | Weiqiang Liao Xiukun Liu Yuqi Li Xu Xu Jinxing Jiang Shaorong Lu Dequan Bao Zhen Wen Xuhui Sun | 2022 | Nano Research2022，15，3： | 2 |

| 6 | Effect of Post-Added Water Amount on Pre-Concentrated Bark Foaming Materials by Mechanical Stirring显示文摘In this study,pre-concentrated bark,furfuryl alcohol and other biomass raw materials were used to prepare foaming materials by high-speed mechanical stirring without using a foaming agent.We investigated the effect of the postadded water amount on the properties of foaming materials.In particular,we determined basic physical properties of these materials,including the limiting oxygen index(LOI),porosity,thermal conductivity,thermogravimetric analysis,pore size distribution,and microstructure.The results of scanning electron microscopy(SEM)indicated that the pore size distribution was uniform and the pore size increased with increasing water volume.Thermogravimetric analysis(TG/DTG)showed that when the temperature reached 410°C,the foam was easily decomposed,the final residual mass was only 2.8%,and water addition had little effect on it.Moreover,the amount of post-added water is 5–30 g,the density and compression strength of the foamed materials gradually decreased,while the degree of pulverization increased.LOI ranged from 26.1%to 30.79%,and porosity ranged from 81%to 83%.The change in water volume greatly affected the foam’s performance,the performance of foamed material deteriorated as the amount of added water increased,but the effect on thermal conductivity was not very obvious.The highest thermal conductivity was only 0.0179 W/(m·K),still providing excellent thermal insulation. | Jinxing Li Jingjing Liao Jun Zhang Xiaojian Zhou Hisham Essawy Guanben Du | 2020 | Journal of Renewable Materials2020，8，12： | 1 |
| 7 | Development of Antioxidant Packaging Film Based on Chinese Bayberry Tannin Extract and Polyvinyl Alcohol显示文摘The current work explores the potential use of commercial Chinese bayberry tannin(BT)to develop antioxidant PVA-based films using solvent casting process for packaging applications.The effect of BT concentration on opa-city,water resistance and antioxidant capacity of resulting films was investigated.Properties like tensile strength,thermal behavior,and morphological aspects were also characterized.The experimental results showed that PVA/BT films formed with uniformly brown color and generally good transparency,offering good antioxidant ability.The PVA film containing BT presented slightly higher water resistance according to the results of moisture content and water vapor permeability,especially at low BT content(<10 wt%).The PVA can be compounded with up to 10 wt%BT without any obvious deterioration in the tensile strength.The PVA/BT films exhibited better thermal degradation behavior compared with PVA alone because of the chemical bonds of PVA-BT and the for-mation of char at high temperature.Based on the results,PVA incorporated with Chinese bayberry tannin may provide broader formulation options for packaging materials with antioxidant action. | Jingjing Liao Jinxing Li Hongyan Wang Yan Zhu Hisham Essawy Guanben Du Xiaojian Zhou | 2022 | Journal of Renewable Materials2022，10，1： | 1 |

| 9 | Identification of atypical T4SS effector proteins mediating bacterial defense显示文摘To remain competitive,proteobacteria use various contact-dependent weapon systems to defend against microbial com-petitors.The bacterial-killing type IV secretion system(T4SS)is one such powerful weapon.It commonly controls the killing/competition between species by secreting the lethal T4SS effector(T4E)proteins carrying conserved XVIPCD domains into competing cells.In this study,we sought knowledge to understand whether the bacterial-killing T4SS-producing bacteria encode T4E-like proteins and further explore their biological functions.To achieve this,we designed a T4E-guided approach to discover T4E-like proteins that are designated as atypical T4Es.Initially,this approach required scientists to perform simple BlastP search to identify T4E homologs that lack the XVIPCD domain in the genomes of T4SS-producing bacteria.These homologous genes were then screened in Escherichia coli to identify antibacterial candidates(atypical T4Es)and their neighboring detoxification proteins,followed by testing their gene cotranscription and validating their physical interactions.Using this approach,we did discover two atypical T4E proteins from the plant-beneficial Lysobacter enzymogenes and the phytopathogen Xanthomonas citri.We also provided substantial evidence to show that the atypical T4E protein Le1637-mediated bacterial defense in interspecies interactions between L.enzymogenes and its competitors.Therefore,the newly designed T4E-guided approach holds promise for detecting functional atypical T4E proteins in bacterial cells. | Xi Shen Zixiang Yang Zihan Li Dan Xiong Jinxing Liao Weimei He Danyu Shen Xiaolong Shao Ben Niu Yongxing He Yong-Gui Gao Guoliang Qian | 2023 | mLife2023，2，3： | 0 |
| 10 | The significance of coal-derived gas in major gas producing countries显示文摘The core of coal-derived gas theory is that coal measure is the gas source, and the hydrocarbon generation of coal measure is dominated by gas and supplemented by oil, so discoveries in related basins are dominated by gas fields. Discovering and developing giant gas fields, especially those super giant gas fields with recoverable reserves more than 1×10^12 m^3, plays a key role in determining whether a country can be a major gas producing country with annual output over 500×10^8 m^3. The coal resource and coal-derived gas reserves are abundant and widespread in the world, and coal-derived gas makes a major contribution to the gas reserves and gas production in the world. By the end of 2017, 13 super giant coal-derived gas fields have been discovered in the world. The total initial recoverable reserves were 49.995 28×10^12 m^3, accounting for 25.8% of the total remaining recoverable reserves (193.5×10^12 m^3) in that year in the world. In 2017, there were 15 giant gas producing countries in the world, with a total gas yield of 28 567×10^8 m^3. Among them, six major coal-derived gas producing countries had a total gas yield of 11 369×10^8 m^3, accounting for 39.8% of total gas yield of major gas producing countries. The Urengoi gas field is a super giant coal-derived gas field with the most cumulative gas production in the world. By the end of 2015, the Urengoi gas field had cumulative gas production of 63 043.96×10^8 m^3, with the highest annual gas yield in the world. Its gas output was 3 300×10^8 m^3 in 1989, accounting for 41.4% and 15.7% of the gas output of Russia and the world, respectively. This study introduces the gas source rocks of the basins with super giant coal-derived gas fields in Russia, Turkmenistan, Netherlands, Mozambique and China, and their significances for these countries becoming giant gas producing countries in the world. | DAI Jinxing NI Yunyan LIAO Fengrong HONG Feng YAO Limiao | 2019 | Petroleum Exploration and Development2019，46，3： | 0 |
| 11 | Preparation of Sea Anemone Peptide Toxin Ap-TxI and Its Insecticidal Activity显示文摘[Objectives]This study was conducted to synthesize sea anemone peptide toxin Ap-TxI and investigate its insecticidal activity. [Methods] The sea anemone linear peptide toxin Ap-TxI was synthesized by the solid-phase peptide synthesis(SPPS), and six cysteines were oxidized to form three disulfide bonds by a three-step directional oxidation method. Then, purification by high performance liquid chromatography(HPLC) and mass spectrometry identification were performed. Finally, the insect cytotoxicity and insecticidal activity of Ap-TxI were studied by the MTT method and insect injection method. [Results] The oxidized peptide Ap-TxI with three disulfide bonds in natural configuration was successfully synthesized by the SPPS method, and its purity was >90% by HPLC analysis. The results of the MTT method showed that Ap-TxI was active on the growth of insect cells sf9, with a half effective dose of 0.2 nM;and the results of the mealworm injection test showed that the polypeptide Ap-TxI had high insecticidal activity with a median lethal dose of 11.7 nM. [Conclusions] The sea anemone peptide toxin Ap-TxI with high insecticidal effect was obtained, laying a foundation for the development of new, efficient and safe biological insecticides. | Yongyi XU Yanling LIAO Qiqi GUO Ming LI Jinxing FU Bingmiao GAO | 2022 | Agricultural Biotechnology2022，11，5： | 0 |

| 13 | Mechanistic insight into the biofilm formation and process performance of a passive aeration ditch(PAD)for decentralized wastewater treatment显示文摘Decentralized wastewater containing elevated salinity is an emerging threat to the local environment and sanitation in remote coastal communities.Regarding the cost and treatment efficiencies,we propose a passive aeration ditch(PAD)using non-woven polyester fabric as a feasible bubbleless aerator and biofilm carrier for wastewater treatment.Consideration has been first given to PAD’s efficacy in treating saline decentralized wastewater,and then to the impact of chemical oxygen demand-to-nitrogen(C/N)ratio and salinity on biofilm formation.A multispecies model incorporating the salinity effect has been developed to depict the system performance and predict the microbial community.Results showed that the PAD system had great capacity for pollutants removal.The biofilm thickness increased at a higher C/N ratio because of the boost of aerobic heterotrophs and denitrifying bacteria,which consequently improved the COD and total nitrogen removal.However,this led to the deterioration of ammonia removal.Moreover,while a higher salinity benefited the biofilm growth,the contaminant removal efficiencies decreased because the salinity inhibited the activity of aerobic heterotrophs and reduced the abundance of nitrifying bacteria inside the biofilm.Based on the model simulation,feed water with salinity below 2%and C/N ratio in a range of 1 to 3 forms a biofilm that can reach relatively high organic matter and ammonia removal.These findings not only show the feasibility of PAD in treatment of saline decentralized wastewater,but also offer a systematic strategy to predict and optimize the process performance. | Jibin Li Jinxing Ma Li Sun Xin Liu Huaiyu Liao Di He | 2022 | Frontiers of Environmental Science & Engineering2022，16，7： | 0 |
| 14 | Sichuan super gas basin in southwest China显示文摘A sedimentary basin is classified as a super basin when its cumulative production exceeds 5 billion barrels of oil equivalent(6.82×10^(8) t of oil or 7931.66×10^(8) m^(3) of gas)and its remaining recoverable resources are at least 5 billion barrels of oil equivalent.By the end of 2019,the total output of oil and gas in Sichuan Basin had been 6569×10^(8) m^(3),the ratio of gas to oil was 80:1,and the total remaining recoverable resources reached 136404×10^(8) m^(3),which makes it as a second-tier super basin.Because the output is mainly gas,it is a super gas basin.The reason why the Sichuan Basin is a super gas basin is that it has four advantages:(1)The advantage of gas source rocks:it has the most gas source rocks(9 sets)among all the basins in China.(2)The advantage of resource quantity:it has the most total remaining recoverable resources among all the basins in China(136404×10^(8) m^(3)).(3)The advantage of large gas fields:it has the most large gas fields(27)among all the basins in China.(4)The advantage of total production:by the end of 2019,the total gas production had been 6487.8×10^(8) m^(3),which ranked the first among all the basins in China.There are four major breakthroughs in natural gas exploration in Sichuan Basin:(1)Breakthrough in shale gas:shale gas was firstly found in the Ordovician Wufeng-Silurian Longmaxi formations in China.(2)Breakthrough in tight sandstone gas:the Triassic Xu2 Member gas reservoir in Zhongba gas field is the first high recovery tight sandstone gas reservoir in China.(3)Breakthrough in giant carbonate gas fields.(4)Breakthrough in ultra-deep gas reservoir.These breakthroughs have led to important progress in different basins across the country.Super basins are classified according to three criteria:accumulative oil and gas production,remaining recoverable resources,tectonic attributes of the basin and the proportion of oil and gas in accumulative oil and gas production. | DAI Jinxing NI Yunyan LIU Quanyou WU Xiaoqi GONG Deyu HONG Feng ZHANG Yanling LIAO Fengrong YAN Zengmin LI Hongwei | 2021 | Petroleum Exploration and Development2021，48，6： | 0 |
| 15 | Assisted Compatibility, and Balanced Regulation of the Mechanical, Thermal, and Antioxidant Activity of Polyvinyl Alcohol-Chinese Bayberry Tannin Extract Films Using Different Di-Aldehydes as Cross-Linkers显示文摘Polyvinyl alcohol(PVA)-based films containing Chinese bayberry tannin(BT)were prepared by cross-linking using glyoxal,glutaraldehyde and dialdehyde starch,individually.The presence of cross-linkers was evident to promote the transparency and decrease the moisture content of PVA/BT films,while the water solubility stayed almost unchanged in the cross-linked PVA/BTfilms.All cross-linkers provided promotion of the water vapor per-meability,mechanical property and thermal stability of PVA/BT films.The best water vapor barrier capacity was found in case of glutaraldehyde cross-linked PVA/BT film,while the highest tensile strength was encountered in case of glyoxal cross-linked PVA/BT films,compared with the uncross-linked films.The scavenging action of the films towards DPPH radical activity was influenced by the nature of each cross-linker.Namely,the PVA/AT film cross-linked by glutaraldehyde acquired the lowest radical scavenging activity in a certain time,suggesting that glutaraldehyde decreased the release rate of BT from PVA.Based on the experimental data,glutaraldehyde and dialdehyde starch could be more suitable for PVA/BT film preparation since they can promote the intermo-lecular interaction of PVA and BT to a reasonable extent. | Jingjing Liao Jinxing Li Fuxian Yang Yan Zhu Hongyan Wang Guanben Du Hisham Essawy Xiaojian Zhou | 2022 | Journal of Renewable Materials2022，10，2： | 0 |
