| 2 | A new way to generate seismic waves for continental crustal exploration显示文摘An airgun experiment was conducted in a reservoir,with the total volume of the airgun array being 6000 cubic inch. The energy released by one excitation was estimated to be 6.68×106 J,which corresponded to a 3.4 kg TNT explosion. A 180 km long profile composed of 100 portable short period seismometers was deployed as a receiver system of the airgun signals. Two remarkable results can be drawn from the experiment: (1) the airgun explosion is harmless to the dam and the fish,and this kind of airguns can be regarded as a green and environmental protection seismic source on land; (2) seismic wave gener-ated by this airgun source can be recorded by permanent stations with offset larger than 200 km. And the wave amplitudes recorded by nearby and remote stations are equivalent to the wave generated by 800 kg dynamite explosion. The airguns can be used as a light to illuminate the continental crustal structure of an area of about 100000 km2. | CHEN Yong ZHANG XianKang QIU XueLin GE HongKui LIU BaoJin WANG BaoShan | 2007 | Chinese Science Bulletin2007，52，16： | 24 |
| 3 | Influencing factors of seismic signals generated by un-tuned large volume airgun array in a land reservoir显示文摘Un-tuned large volume airgun array in a water reservoir is recently proposed as a new way to generate seismic waves on land. It can be used to explore the earth velocity structure and its temporal variations as well.However, the characteristics of seismic signals(especially far-field signals) from an airgun array in a reservoir and its affecting factors(firing pressure, airgun towing depth,water level of the reservoir, etc.) has not been adequately studied. We analyzed the seismic data collected from field experiments at Binchuan Transmitting Seismic Station in2011 and 2013 and found that(1) The similarity of seismic signals decrease with distance, which is most likely induced by the decay of signal amplitude and signal to noise ratio(SNR);(2) The amplitudes of far-field airgun signals are almost linearly proportional to the firing pressure;(3) The towing depth of airgun has less effects on the far-field signals;(4) The amplitudes of far-field airgun signals are proportional to the water level of the reservoir. | Meng Chen Wei Yang Weitao Wang Baoshan Wang Hongkui Ge Li Chen Yansheng Ding Jiyan Qiao Yong Chen | 2014 | Earthquake Science2014，27，4： | 19 |
| 4 | Protein kinases in plant responses to drought, salt,and cold stress显示文摘Protein kinases are major players in various signal transduction pathways. Understanding the molecular mechanisms behind plant responses to biotic and abiotic stresses has become critical for developing and breeding climate-resilient crops. In this review,we summarize recent progress on understanding plant drought, salt, and cold stress responses, with a focus on signal perception and transduction by different protein kinases, especially sucrose nonfermenting1(SNF1)-related protein kinases(Sn RKs),mitogen-activated protein kinase(MAPK) cascades,calcium-dependent protein kinases(CDPKs/CPKs),and receptor-like kinases(RLKs). We also discuss future challenges in these research fields. | Xuexue Chen Yanglin Ding Yongqing Yang Chunpeng Song Baoshan Wang Shuhua Yang Yan Guo Zhizhong Gong | 2021 | Journal of Integrative Plant Biology2021，63，1： | 13 |
| 5 | Visible light photodegradation of methylene blue by AgBr-TiO_2/SiO_2@Fe_3O_4 magnetic photocatalysts显示文摘Visible photoactive AgBr/TiO_2 was immobilized on a SiO_2@Fe_3O_4 magnetic support by solvothermal and sol-gel methods to form a AgBr-TiO_2/SiO_2@Fe_3O_4 magnetic photocatalyst.Samples were characterized by X-ray diffraction,high-resolution transmission electron microscopy and magnetometry.Hetero-structured AgBr/TiO_2 was well seeded on the shell-core SiO_2@Fe_3O_4 structure.The AgBr-TiO_2/SiO_2@Fe_3O_4 magnetic photocatalyst exhibited high photocatalytic activity in the degradation of methylene blue under visible light.The photocatalyst was superparamagnetic,which is beneficial for facile magnetic separation. | Jianjun Liu Shengli Zuo Liming Yu Yingchun Yu Baoshan Li Pengwan Chen | 2013 | Particuology2013，11，6： | 7 |
| 6 | Stearic Acid/Copper Foam as Composite Phase Change Materials for Thermal Energy Storage显示文摘The application of stearic acid in the latent thermal energy storage(LTES) systems is hindered due to its lower heat transfer rate. Stearic acid(SA) was blended with copper foam(CF) of pore numbers per inch(PPI) of 5, 20, and 40 to prepare composite phase change materials via a molten impregnation method. The thermal physical properties including latent heat, phase change temperature, and thermal energy storage density of composites were characterized. The thermogravimetric analysis indicated that the loadages of SA of SA/CF(5 PPI), SA/CF(20 PPI), and SA/CF(40 PPI) were 74.69%, 71.03%, and 63.54%, respectively;The latent heat of SA/CF(5 PPI), SA/CF(20 PPI), and SA/CF(40 PPI) were determined to 139.9 J·g^-1, 132.7 J·g^-1, and 117.8 J·g^-1, respectively. Meanwhile, the infrared thermal images of SA and SA/CF composites were provided to demonstrate the thermal energy storage and dissipation capability intuitively by the temperature response and surface temperature distribution. The infrared thermal images indicated the addition of CF also reduced the fluidity of liquid SA, and the SA/CF(40 PPI) had better internal heat transfer uniformity and thermal diffusion performance than SA/CF(5 PPI) and SA/CF(20 PPI). All these thermal properties suggested SA/CF(40 PPI) has the potential application in the latent thermal energy storage. | LI Chuanchang ZHAO Xinbo ZHANG Bo XIE Baoshan HE Zhangxing CHEN Jian HE Jianjun | 2020 | Journal of Thermal Science2020，29，2： | 5 |
| 7 | Uptake of graphene enhanced the photophosphorylation performed by chloroplasts in rice plants显示文摘New and enhanced functions were potentially imparted to the plant organelles after interaction with nanoparticles.In this study,we found that∼44%and∼29%of the accumulated graphene in the rice leaves passively transported to the chloroplasts and thylakoid,respectively,significantly enhanced the fluorescence intensity of chloroplasts,and promoted about 2.4 times higher adenosine triphosphate production than that of controls.The enhancement of graphene on the photophosphorylation was ascribed to two reasons:One is that graphene facilitates the electron transfer process of photosystem II in thylakoid,and the other is that graphene protects the photosystem II against photo-bleaching by acting as a scavenger of reactive oxygen species.Overall,our work here confirmed that graphene translocating in the thylakoid promoted the photosynthetic activity of chloroplast in vivo and in vitro,providing new opportunities for designing biomimetic materials to enhance the solar energy conversion systems,especially for repairing or increasing the photosynthesis activity of the plants grown under stress environment. | Kun Lu Danlei Shen Shipeng Dong Chunying Chen Sijie Lin Shan Lu Baoshan Xing Liang Mao | 2020 | Nano Research2020，13，12： | 4 |

| 10 | Influence of cosmic radiation on lymphocyte micronucleus,serum lipid peroxide and antioxidation capacity in aircrew members显示文摘This study looks into the influence of cosmic radiation at high altitudes on human bodies. Results reveal that the cytokinesis-block micronuclei (CBMN) and conventional cultured micronuclei in peripheral blood lymphocytes, serum levels of lipid peroxide, superoxide dismutase, and the total antioxidation capacity by chemical colorimetry all increased significantly in aircrew members. There exists a linear relationship between the CBMN and the average annual effective doses of radiation received or the average annual flying hours. With both of them, a trend shows that the serum lipid peroxide levels increase as well. Either the lipid peroxide or CBMN can sensitively reflect the recent changes in flight load. These findings indicate that cosmic radiation impairs the stability of chromosomes and genome, and induces lipid oxidative damage in aircrews; Lymphocyte CBMN and serum lipid peroxide can be used as monitoring indicators in the cosmic radiation protection for aircrew members. | CHEN Weiru FENG Yingjin LIU Jiangkuang ZHANG Haili GUO Ying ZHANG Yan DUAN Shiying PENG Xintao SUN Tianping JIA Baoshan ZHAO Junxian LI Hua | 2002 | Chinese Science Bulletin2002，47，8： | 3 |
| 11 | Mica-stabilized polyethylene glycol composite phase change materials for thermal energy storage显示文摘Mica was used as a supporting matrix for composite phase change materials(PCMs)in this work because of its distinctive morphology and structure.Composite PCMs were prepared using the vacuum impregnation method,in which mica served as the supporting material and polyethylene glycol(PEG)served as the PCM.Fourier transform infrared and X-ray diffraction analysis confirmed that the addition of PEG had no effect on the crystal structure of mica.Moreover,no chemical reaction occurred between PEG and mica during the vacuum impregnation process,and no new substance was formed.The maximum load of mica-stabilized PEG was 46.24%,the phase change temperature of M_(400)/PEG was 46.03℃,and the latent heat values of melting and cooling were 77.75 and 77.73 J·g^(−1),respectively.The thermal conductivity of M_(400)/PEG was 2.4 times that of pure PEG.The thermal infrared images indicated that the thermal response of M_(400)/PEG improved relative to that of pure PEG.The leakage test confirmed that mica could stabilize PEG and that M_(400)/PEG had great form-stabilized property.These results demonstrate that M_(400)/PEG has potential in the field of building energy conservation. | Dongyao Zhang Chuanchang Li Niangzhi Lin Baoshan Xie Jian Chen | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，1： | 3 |

| 13 | Understanding divergent domestication traits from the whole-genome sequencing of swamp-and river-buffalo populations显示文摘Domesticated buffaloes have been integral to rice-paddy agro-ecosystems formillennia,yet relatively little is known about the buffalo genomics.Here,we sequenced and assembled reference genomes for both swamp and river buffaloes and we re-sequenced 230 individuals(132 swamp buffaloes and 98 river buffaloes)sampled from across Asia and Europe.Beyond the many actionable insights that our study revealed about the domestication,basic physiology and breeding of buffalo,we made the striking discovery that the divergent domestication traits between swamp and river buffaloes can be explained with recent selections of genes on social behavior,digestion metabolism,strengths and milk production. | Xier Luo Yu Zhou Bing Zhang Yi Zhang Xiaobo Wang Tong Feng Zhipeng Li Kuiqing Cui Zhiqiang Wang Chan Luo Hui Li Yanfei Deng Fenghua Lu Jianlin Han Yongwang Miao Huaming Mao Xiaoyan Yi Cheng Ai Shigang Wu Alun Li Zhichao Wu Zijun Zhuo Do Da Giang Bikash Mitra Mohammad Farhad Vahidi Shahid Mansoor Sahar Ahmed Al-Bayatti Eka Meutia Sari Neena Amatya Gorkhali Sigit Prastowo Laiba Shafique Guoyou Ye Qian Qian Baoshan Chen Deshun Shi Jue Ruan Qingyou Liu | 2020 | National Science Review2020，7，3： | 3 |
| 14 | Experiment and Simulation of Large Capacity Air-guns in Deep Structure Exploration显示文摘The air-gun source has important applications as a new, environmentally, green active source in regional scale deep exploration. In the past, the air gun source was used mainly in small-scale, high-resolution shallow oil exploration, but has a lack of adequate research in deep exploration. In order to study the selection of work parameters and field conditions of the air gun source in deep exploration, this paper does the following work: ① analyze the characteristics of the air gun source using air gun experiments; ② simulate the air gun signal and air gun-array signal based on the theory of free bubble oscillation to analyze the influence of bubble oscillation and study the wavelet energy and spectrum characteristics needed in deep exploration; ③ on the basis of theoretical simulation, study the influence of work parameters, such as air-gun capacity, work stress and depth on air gun signal and analyze the influence of air-gun array inspired moment and spacing of different air guns on air gun-array signals; and ④ study energy reflection and transmission coefficients for different underwater interfaces, which is very useful for choosing suitable field conditions. | Tang Jie Wang Baoshan Ge Hongkui Chen Yong | 2009 | Earthquake Research in China2009，23，4： | 3 |
| 15 | Study on the Source Characteristics of Downhole Airgun with Different Excitation Environments显示文摘The measurement of underground medium variation using a repeated artificial source has gradually become an important goal to pursue. In recent years,we have developed and improved a technology system with large capacity airguns excited in land reservoirs by transplanting marine seismic exploration technology. The excitation effect has a close relationship to airgun capacity,water environment,and excitation conditions. In view that large capacity airgun must be excited without a water environment,we expand the system to use in downhole. Based on the BHS-2200 LL downhole airgun with a capacity of250in3,this paper carries out a comparative analysis on the characteristics of an airgun source excited in 0. 2m- and 5. 0m-diameter wells,and the results show that:( 1) The dominant frequency of the airgun signal excited in a 5. 0m well is mainly from 10 Hz to40Hz,lower than that in a 0. 2m well,and the larger body of water is good for bubble oscillation.( 2) In terms of exciting energy,the signal excited in a 5. 0m well has stronger energy than in a 0. 2m well,with a difference of 1 order in magnitude,and the signal can be detected up to 9km excited in a 5. 0m well with a single shot.( 3) The airgun signal has good repeatability in both excitation wells. The downhole airgun excitation technology system has potential application in dynamic monitoring near a fault zone with a small scale range, exploration of oil and mineral resources, and modern urban geophysical environment. | Yang Wei Wang Baoshan Liu Zhengyi Yang Jun Li Xiaobin Chen Yong | 2016 | Earthquake Research in China2016，30，3： | 2 |

| 17 | OTUD5 promotes innate antiviral and antitumor immunity through deubiquitinating and stabilizing STING显示文摘Stimulator of interferon genes(STING)is an adaptor protein that is critical for effective innate antiviral and antitumor immunity.The activity of STING is heavily regulated by protein ubiquitination,which is fine-tuned by both E3 ubiquitin ligases and deubiquitinases.Here,we report that the deubiquitinase OTUD5 interacts with STING,cleaves its K48-linked polyubiquitin chains,and promotes its stability.Consistently,knockout of OTUD5 resulted in faster turnover of STING and subsequently impaired type I IFN signaling following cytosolic DNA stimulation.More importantly,Lyz2-Cre Otud5^(fl/Y) mice and CD11-Cre Otud5^(fl/Y) mice showed more susceptibility to herpes simplex virus type 1(HSV-1)infection and faster development of melanomas than their corresponding control littermates,indicating that OTUD5 is indispensable for STING-mediated antiviral and antitumor immunity.Our data suggest that OTUD5 is a novel checkpoint in the cGAS-STING cytosolic DNA sensing pathway. | Yunyun Guo Fei Jiang Lingli Kong Haifeng Wu Honghai Zhang Xiaorong Chen Jian Zhao Baoshan Cai Yanqi Li Chunhong Ma Fan Yi Lei Zhang Bingyu Liu Yi Zheng Lingqiang Zhang Chengjiang Gao | 2021 | Cellular & Molecular Immunology2021，18，8： | 2 |
| 18 | Distributions and air-sea fluxes of CO_2 in the summer Bering Sea显示文摘The 3rd Chinese National Arctic Research Expedition(CHINARE–Arctic III) was carried out from July to September in 2008. The partial pressure of CO2(pCO2) in the atmosphere and in surface seawater were determined in the Bering Sea during July 11–27, 2008, and a large number of seawater samples were taken for total alkalinity(TA) and total dissolved inorganic carbon(DIC) analysis. The distributions of CO2 parameters in the Bering Sea and their controlling factors were discussed. The pCO2 values in surface seawater presented a drastic variation from 148 to 563 μatm(1 μatm = 1.013 25×10-1 Pa). The lowest pCO2 values were observed near the Bering Sea shelf break while the highest pCO2 existed at the western Bering Strait. The Bering Sea generally acts as a net sink for atmospheric CO2 in summer. The air-sea CO2 fluxes in the Bering Sea shelf, slope, and basin were estimated at-9.4,-16.3, and-5.1 mmol/(m2·d), respectively. The annual uptake of CO2 was about 34 Tg C in the Bering Sea. | CHEN Liqi GAO Zhongyong SUN Heng CHEN Baoshan CAI Wei-jun | 2014 | Acta Oceanologica Sinica2014，33，6： | 2 |
| 19 | Multiple structure graphite stabilized stearic acid as composite phase change materials for thermal energy storage显示文摘This paper used 3 types of graphite with different physical structures as the porous matrix to prepare composite phase change materials(PCMs),and investigated their photo-thermal conversion performance and application in battery thermal management.Multiple structure graphite minerals,including microcrystalline graphite(MG),scale graphite(SG),and expanded graphite(EG)were used as porous matrix,while stearic acid(SA)acts as the phase change material.The vacuum impregnation method was applied to prepare SA/MG,SA/SG,SA/EG,and SA/MG1,and SA/EG1was/were prepared by the ethyl alcohol method.Results show that the thermal conductivities of all composite phase change materials were 10.82 to 22.06 times higher than that of the pure SA.Thermogravimetric(TG)analysis showed that the loadages of SA were 43.61%,18.74%,and 92.66%for SA/MG,SA/SG,and SA/EG respectively.The load rates of SA were 18.98%and 18.88%for SA/MG1 and SA/EG1,respectively.For the 3 types of graphite materials of different dimensions,the BET(Brunauer,Emmett,and Teller)surface area determines the maximum load of SA.The Fourier-transform infrared(FTIR)and X-ray diffraction(XRD)results indicated that there was good compatibility between the SA and the supports.The SA/EG1 has better thermophysical properties in heat energy storage and release process.The thermal infrared images show that SA/EG1 has higher sensitivity to the temperature changes.SA/EG1 has better photo-heat conversion performance than SA/SG and SA/MG1 attributed to the multilayer structure of EG.SA/EG has better thermal management performance in the Li-ion batteries discharge process. | Xinbo Zhao Chuanchang Li Kaihao Bai Baoshan Xie Jian Chen Qingxia Liu | 2022 | International Journal of Mining Science and Technology2022，32，6： | 2 |
