| 1 | Experimental comparison between aircraft fuel tank inerting processes using NEA and MIG显示文摘Fuel tank inerting technologies are able to reduce the fire risk by injection of inert gas into the ullage or fuel, the former called ullage washing and the latter fuel scrubbing. The Green On-Board Inert Gas Generation System(GOBIGGS) is a novel technology based on flameless catalytic combustion, and owning to its simple structure and high inerting efficiency, it has received a lot of attentions. The inert gas in the GOBIGGS is mainly comprised of CO_2, N_2, and O_2(hereinafter, Mixed Inert Gas(MIG)), while that in the On-Board Inert Gas Generation System(OBIGGS), which is one of the most widely used fuel tank inerting technologies, is NitrogenEnriched Air(NEA). The solubility of CO_2 is nearly 20 times higher than that of N_2 in jet fuels,so the inerting capability and performance are definitely disparate if the inert gas is selected as NEA or MIG. An inerting test bench was constructed to compare the inerting capabilities between NEA and MIG. Experimental results reveal that, if ullage washing is adopted, the variations of oxygen concentrations on the ullage and in the fuel are nearly identical no matter the inert gas is NEA or MIG. However, the ullage and dissolved oxygen concentrations of MIG scrubbing are always higher than those of NEA scrubbing. | Lei SHAO Weihua LIU Chaoyue LI Shiyu FENG Chenchen WANG Jun PAN | 2018 | Chinese Journal of Aeronautics2018，31，7： | 11 |
| 2 | Interferon-armed RBD dimer enhances the immunogenicity of RBD for sterilizing immunity against SARS-CoV-2显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has caused a global crisis,urgently necessitating the development of safe,efficacious,convenient-to-store,and low-cost vaccine options.A major challenge is that the receptor-binding domain(RBD)-only vaccine fails to trigger long-lasting protective immunity if used alone for vaccination. | Shiyu Sun Yueqi Cai Tian-Zhang Song Yang Pu Lin Cheng Hairong Xu Jing Sun Chaoyang Meng Yifan Lin Haibin Huang Fang Zhao Silin Zhang Yu Gao Jian-Bao Han Xiao-Li Feng Dan-Dan Yu Yalan Zhu Pu Gao Haidong Tang Jincun Zhao Zheng Zhang Jiaming Yang Zhenxiang Hu Yang-Xin Fu Yong-Tang Zheng Hua Peng | 2021 | Cell Research2021，31，9： | 7 |
| 3 | Measurement of mass diffusion coefficients of O_2 in aviation fuel through digital holographic interferometry显示文摘The experimental apparatus to measure the mass diffusion coefficients of O2 in aviation fuel was constructed based on the digital holographic interferometry method. The theory of mass diffusion coefficient and interference image processing were introduced in detail. The accuracy of the experiment was verified by measuring the mass diffusion coefficient of 0.33 mol/L KCl in aqueous solution at 298.15 K. The mass diffusion coefficients of O_2 in RP3 and RP5 aviation fuels were measured at temperature from 278.15 K to 333.15 K, and the Arrhenius equation was employed to fit the experimental data. In terms of the Stokes-Einstein equation, the viscosities of these two aviation fuels were tested to estimate the correlation among mass diffusion coefficient, viscosity and temperature. A uniform polynomial calculation correlation was proposed to predict the mass diffusion coefficients of O_2 in both RP3 and RP5 aviation fuels, and its accuracy is considerably higher than that of the Stokes-Einstein equation. | Chaoyue LI Weihua LIU Xiaotian PENG Lei SHAO Shiyu FENG | 2019 | Chinese Journal of Aeronautics2019，32，5： | 7 |
| 4 | Micro-droplet Digital Polymerase Chain Reaction and Real-Time Quantitative Polymerase Chain Reaction Technologies Provide Highly Sensitive and Accurate Detection of Zika Virus显示文摘The establishment of highly sensitive diagnostic methods is critical in the early diagnosis and control of Zika virus(ZIKV)and in preventing serious neurological complications of ZIKV infection. In this study, we established micro-droplet digital polymerase chain reaction(ddPCR) and real-time quantitative PCR(RT-qPCR) protocols for the detection of ZIKV based on the amplification of the NS5 gene. For the ZIKV standard plasmid, the RT-qPCR results showed that the cycle threshold(Ct) value was linear from 10~1 to 10~8 copy/l L, with a standard curve R^2 of 0.999 and amplification efficiency of 92.203%;however, a concentration as low as 1 copy/l L could not be detected. In comparison with RT-qPCR, the dd PCR method resulted in a linear range of 10~1–10~4 copy/l L and was able to detect concentrations as low as 1 copy/l L. Thus, for detecting ZIKV from clinical samples, RT-qPCR is a better choice for high-concentration samples(above 10~1 copy/l L),while ddPCR has excellent accuracy and sensitivity for low-concentration samples. These results indicate that the ddPCR method should be of considerable use in the early diagnosis, laboratory study, and monitoring of ZIKV. | Yuan Hui Zhiming Wu Zhiran Qin Li Zhu Junhe Liang Xujuan Li Hanmin Fu Shiyu Feng Jianhai Yu Xiaoen He Weizhi Lu Weiwei Xiao Qinghua Wu Bao Zhang Wei Zhao | 2018 | Virologica Sinica2018，33，3： | 6 |
| 5 | Applications of membrane distillation technology in energy transformation process-basis and prospect显示文摘Membrane distillation technology is a new type of efficient separation technology that combines traditional distillation technology and membrane separation technology. In the study, applications of membrane distillation technology in thermal engineering and refrigerating engineering with typical energy transformation process were presented. Desorption and regeneration process of saline solution by vacuum membrane distillation was proposed on the basis of the concentration and separation properties of membrane distillation. Membrane distillation technology could be used in lithium bromide absorption refrigeration system, energy storage system, and the regeneration process of liquid desiccant solution in temperature-humidity independent control air-conditioning system. The aim of the applications was to use the low-grade energy such as waste heat, solar energy and geothermal energy adequately and to improve the available temperature difference of heat source. According to latent heat transfer and thermal conduction across the membrane in direct contact membrane distillation process, a novel membrane heat exchanger with both heat transfer and mass transfer processes was proposed. The heat exchanger could be used as the solution heat exchanger of lithium bromide absorption refrigeration system and as the special heat exchanger that recovered heat and pure water simultaneously. Some feasible process flows about the applications of membrane distillation technology to energy transformation process were listed and analyzed. Finally, future research emphases were indicated. | WANG ZanShe GU ZhaoLin FENG ShiYu LI Yun | 2009 | Chinese Science Bulletin2009，54，16： | 6 |

| 7 | Methods for large reciprocating compressor capacity control: A review based on pulse signal concept显示文摘Large reciprocating compressors are important equipment used in a wide range of process industries. Most of these compressors have huge power requirements and their capacity often needs to be regulated. Advanced technologies in compressor capacity control are effective approaches for saving large amounts of energy in process industries. This paper reviews the basic theories and the state of the art of the capacity control technologies. In particular, a compressor working procedure is first presented using an analogy to the pulse signal concept. Compressor capacity control methods are classified into pulse frequency modulation and pulse amplitude modulation from a perspective of pulse signal processing. The mechanisms and feasibility of some important methods, including dead volume variable control, partial-stroke and full-stroke suction valve opening, are reviewed. Based on the pulse signal concept, a duty cycle regulation method for capacity control is introduced, and the performance and implementation of the new method are compared with those of the existing suction valve opening methods. The duty cycle regulation method has integrated advantages over the other methods in terms of regulating precision, pressure stability, energy saving and reliability. All the suction valve opening methods can cause gas reflux, resulting in the so-called breathing effect. The breathing effect has negative effects on regulation performance and compressor security, which needs further investigation in the future. | GU ZhaoLin HOU XiongPo WANG ZanShe FENG ShiYu GAO XiuFeng LI Yun | 2011 | Chinese Science Bulletin2011，56，19： | 4 |
| 8 | High-efficiency Joining of C_f/Al Composites and TiAl Alloys under the Heat Effect of Laser-ignited Self-propagating High-temperature Synthesis显示文摘The aim of this study was to develop a high-efficiency joining method of Cf/Al composites and TiA l alloys under the heat effect of laser-ignited self-propagating high-temperature synthesis(SHS). The SHS reaction of Ni–Al–Zr interlayer was induced by laser beam and acted as local high-temperature heat source during the joining. Sound joint was obtained and verified the feasibility of this joining method. Effect of filler metals on the joint microstructure and shear strength was evaluated. When the joining pressure was 2 MPa with additive filler metals, joint shear strength reached the maximum of 41.01 MPa. | Zhuoran Li Guangjie Feng Shiyu Wang Shicheng Feng | 2016 | Journal of Materials Science & Technology2016，32，11： | 4 |
| 9 | NiSe_(2)/Ni(OH)_(2) Heterojunction Composite through Epitaxial-like Strategy as High-Rate Battery-Type Electrode Material显示文摘Constructing heterojunction is a promising way to improve the charge transfer efficiency and can thus promote the electrochemical properties.Herein,a facile and effective epitaxial-like growth strategy is applied to NiSe2 nano-octahe-dra to fabricate the NiSe2-(100)/Ni(OH)2-(110)heterojunction.The heterojunction composite and Ni(OH)2(performing high electrochemical activity)is ideal high-rate battery-type supercapacitor electrode.The NiSe2/Ni(OH)2 electrode exhibits a high specific capacity of 909 C g^-1 at 1 A g^-1 and 597 C g^-1 at 20 A g^-1.The assembled asymmetric supercapacitor composed of the NiSe2/Ni(OH)2 cathode and p-phenylenediamine-functional reduced graphene oxide anode achieves an ultrahigh specific capacity of 303 C g^-1 at 1 A g^-1 and a superior energy density of 76.1 Wh kg^-1 at 906 W kg^-1,as well as an outstanding cycling stability of 82%retention for 8000 cycles at 10 A g^-1.To the best of our knowledge,this is the first example of NiSe2/Ni(OH)2 heterojunction exhibiting such remarkable supercapacitor performance.This work not only provides a promising candidate for next-generation energy storage device but also offers a possible universal strategy to fabricate metal selenides/metal hydroxides heterojunctions. | Hao Mei Zhaodi Huang Ben Xu Zhenyu Xiao Yingjie Mei Haobing Zhang Shiyu Zhang Dacheng Li Wenpei Kang Dao Feng Sun | 2020 | Nano-Micro Letters2020，12，5： | 3 |
| 10 | Engineered neutrophil apoptotic bodies ameliorate myocardial infarction by promoting macrophage efferocytosis and inflammation resolution显示文摘Inflammatory response plays a critical role in myocardial infarction(MI)repair.The neutrophil apoptosis and subsequent macrophage ingestion can result in inflammation resolution and initiate regeneration,while the therapeutic strategy that simulates and enhances this natural process has not been established.Here,we constructed engineered neutrophil apoptotic bodies(eNABs)to simulate natural neutrophil apoptosis,which regulated inflammation response and enhanced MI repair.The eNABs were fabricated by combining natural neutrophil apoptotic body membrane which has excellent inflammation-tropism and immunoregulatory properties,and mesoporous silica nanoparticles loaded with hexyl 5-aminolevulinate hydrochloride(HAL).The eNABs actively targeted to macrophages and the encapsulated HAL simultaneously initiated the biosynthesis pathway of heme to produce anti-inflammatory bilirubin after intracellular release,thereby further enhancing the anti-inflammation effects.In in vivo studies,the eNABs efficiently modulated inflammation responses in the infarcted region to ameliorate cardiac function.This study demonstrates an effective biomimetic construction strategy to regulate macrophage functions for MI repair. | Lili Bao Geng Dou Ran Tian Yajie Lv Feng Ding Siying Liu Ruifeng Zhao Lu Zhao Jun Zhou Lin Weng Yan Dong Bei Li Shiyu Liu Xin Chen Yan Jin | 2022 | Bioactive Materials2022，7，3： | 3 |
| 11 | Oxygen concentration variation in ullage influenced by dissolved oxygen evolution显示文摘To determine the oxygen concentration variation in ullage that results from dissolved oxygen evolution in an inert aircraft fuel tank,the CFD method with a mass transfer source is applied in the present study.An experimental system is also designed to evaluate the accuracy of the CFD simulations.The dissolved oxygen evolution is simulated under different conditions of fuel load and initial oxygen concentration in ullage of an inert fuel tank with stimulations of heating and pressure decrease.The increase in the oxygen concentration in ullage ranges from 0.82%to 5.92%upon stimulation of heating and from 0.735%to 12.36%upon stimulation of a pressure decrease for an inert ullage in the simulations.The heating accelerates the release of the dissolved oxygen from the fuel by increasing the mass transfer rate in the mass transfer source and decreasing the pressure,thereby accelerating the dissolved oxygen evolution by increasing the concentration difference between the gas and the fuel.The time constant that represents the oxygen evolution rate is independent of the initial oxygen concentration in ullage of an inert tank but depends closely on the fuel load,temperature and pressure.The time constant can be fitted using a polynomial equation relating the fuel load to temperature in the heating stimulation with an accuracy of 4.77%.Upon stimulation of a pressure decrease,the time constant can be expressed in terms of the fuel load and the pressure,with an accuracy of 5.02%. | Shiyu FENG Chaoyue LI Xiaotian PENG Tao WEN Yan YAN Rongjie JIANG Weihua LIU | 2020 | Chinese Journal of Aeronautics2020，33，7： | 3 |
| 12 | Reliable and Efficient Agrobacterium tumefaciens-Mediated Genetic Transformation of Dianthus spiculifolius显示文摘Dianthus spiculifolius is a perennial herbaceous flower with strong environmental adaptability and is an important ornamental ground cover plant.In this study,seeds of D.spiculifolius were used as explants for callus induction,adventitious bud differentiation,and rooting by adding different concentrations of 2,4-dichlorophenoxyacetic acid(2,4-D),6-benzyl aminopurine(6-BA),and naphthaleneacetic acid(NAA)to Murashige and Skoog medium.The calli generated were co-cultured with Agrobacterium tumefaciens EHA105 containing pBI121-GUS or pBI121-GFP plasmids for 30 min,and transgenic regenerated plants were obtained by kanamycin(30mg·L^−1)screening.RT-PCR confirmed the stable expression of the exogenous GUS and GFP genes in the D.spiculifolius.Theβ-glucuronidase(GUS)histochemical staining confirmed GUS gene expression in transgenic calli,adventitious buds,and regenerated plants of D.spiculifolius.The green fluorescent protein(GFP)visual analysis showed GFP gene expression in transgenic calli.Furthermore,subcellular localization analysis showed that the three organelle marker proteins were not only successfully expressed but also accurately localized to their corresponding organelles in D.spiculifolius callus cells.These results indicated a successful establishment of a reliable and efficient A.tumefaciens-mediated genetic transformation system,which will contribute to functional gene research and genetic improvement of D.spiculifolius. | Jingang Wang Shiyue Liu Hongping Ma Ye Tao Shuang Feng Shufang Gong Jinzhu Zhang Aimin Zhou | 2020 | Horticultural Plant Journal2020，6，3： | 2 |

| 16 | Longitudinal virological changes and underlying pathogenesis in hospitalized COVID-19 patients in Guangzhou,China显示文摘Prolonged viral RNA shedding and recurrence of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)in coronavirus disease 2019(COVID-19)patients have been reported.However,the clinical outcome and pathogenesis remain unclear.In this study,we recruited 43 laboratory-confirmed COVID-19 patients.We found that prolonged viral RNA shedding or recurrence mainly occurred in severe/critical patients(P<0.05).The average viral shedding time in severe/critical patients was more than 50 days,and up to 100 days in some patients,after symptom onset.However,chest computed tomography gradually improved and complete absorption occurred when SARS-CoV-2 RT-PCR was still positive,but specific antibodies appeared.Furthermore,the viral shedding time significantly decreased when the A1,430G or C12,473T mutation occurred(P<0.01 and FDR<0.01)and increased when G227A occurred(P<0.05 and FDR<0.05).High IL1R1,IL1R2,and TNFRSF21 expression in the host positively correlated with viral shedding time(P<0.05 and false discovery rate<0.05).Prolonged viral RNA shedding often occurs but may not increase disease damage.Prolonged viral RNA shedding is associated with viral mutations and host factors. | Zhengtu Li Yinhu Li Ruilin Sun Shaoqiang Li Lingdan Chen Yangqing Zhan Mingzhou Xie Jiasheng Yang Yanqun Wang Airu Zhu Guoping Gu Le Yu Shuaicheng Li Tingting Liu Zhaoming Chen Wenhua Jian Qian Jiang Xiaofen Su Weili Gu Liyan Chen Jing Cheng Jincun Zhao Wenju Lu Jinping Zheng Shiyue Li Nanshan Zhong Feng Ye | 2021 | Science China(Life Sciences)2021，64，12： | 1 |
| 17 | An Algorithm to Recognize the Target Object Contour Based on 2D Point Clouds by Laser-CCD-Scanning显示文摘For a vision measurement system consisted of laser-CCD scanning sensors, an algorithm is proposed to extract and recognize the target object contour. Firstly, the two-dimensional(2D) point cloud that is output by the integrated laser sensor is transformed into a binary image. Secondly, the potential target object contours are segmented and extracted based on the connected domain labeling and adaptive corner detection. Then, the target object contour is recognized by improved Hu invariant moments and BP neural network classifier. Finally, we extract the point data of the target object contour through the reverse transformation from a binary image to a 2D point cloud. The experimental results show that the average recognition rate is 98.5% and the average recognition time is 0.18 s per frame. This algorithm realizes the real-time tracking of the target object in the complex background and the condition of multi-moving objects. | MAO Hongyong SHI Duanwei ZHOU Ji XU Pan CHEN Shiyu XU Yuxiang FENG Fan | 2015 | Wuhan University Journal of Natural Sciences2015，20，4： | 1 |
| 18 | Application of high-frequency magnetotelluric method in porphyry copper deposit exploration:a case study of Duobaoshan deposit area显示文摘The Duobaoshan mine area in Heilongjiang is located in the northeast section of Xingmeng orogenic belt and is in the west side of Hegang Mountain-Heihe fault zone. There exist many deposits in this area,and its metallogenic conditions are superior,which has been one of the hotspots in geological prospecting and metallogenic research in Northeast China. On the basis of previous studies,the authors used the EH-4 electromagnetic imaging system to carry out the data acquisition of three survey lines in Woduhe Village,Duobaoshan Town,Nenjiang County. Through the analysis of apparent resistivity section under TE and TM polarization modes,integrating regional geological data,it is concluded that:(1) the electrical characteristics of the metal ore in this area show a relatively low resistance,and according to its resistivity difference with surrounding rocks,the geometrical structures and apparent resistivity parameters of the low resistivity bodies in the lower section of the survey line are defined,and the electrical anomalies can be identified;(2)faults F1 and F2 may have a good metallogenic environment,so they are recommended for further exploration;(3) low resistance metal ore bodies have good correlation with local small structures or faults,which may play an iconic role for the delineation of key target areas;(4) in the process of using apparent resistivity to define the geometric structures of ore bodies underground,comprehensive analysis integrating the advantages of TE and TM models should be carry out to achieve more reliable inversion results. | LIU Caihua QU Xin FENG Xuan TTAN You LIU Yang QIAO Hanqing WANG Shiyu | 2017 | Global Geology2017，20，4： | 1 |
| 19 | Mechanisms of allicin exposure for the sludge fermentation enhancement:Focusing on the fermentation processes and microbial metabolic traits显示文摘As a frequently used product with antimicrobial activity,consumed allicin might be dis-charged and concentrated in waste-activated sludge(WAS).However,the influence of al-licin(as an exogenous pollutant)on WAS fermentation has not been clearly revealed.This study aimed to disclose the impacts of allicin on volatile fatty acid(VFA)generation dur-ing WAS fermentation.The results showed that the appropriate presence of allicin(10 mg/g TSS)significantly enhanced the VFA yield(1894 versus 575 mg COD/L in the control)with increased acetate proportion(24.3%).Further exploration found that allicin promoted WAS solubilization,hydrolysis and acidification simultaneously.Metagenomic analysis revealed that the key genes involved in extracellular hydrolysis metabolism(i.e.,CAZymes),mem-brane transport(i.e.,gtsA and ytfT),substrate metabolism(i.e.,yhdR and pfkC)and fatty acid synthesis(i.e.,accA and accD)were all highly expressed.Allicin also induced the bacteria to produce more signalling molecules and regulate cellular functions,thereby enhancing the microbial adaptive and regulatory capacity to the unfavourable environment.Moreover,the variations in fermentative microbes and their contributions to the upregulation of func-tional genes(i.e.,ytfR,gltL,INV,iolD and pflD)for VFA generation were disclosed.Overall,the simultaneous stimulation of functional microbial abundances and metabolic activities contributed to VFA production in allicin-conditioned reactors. | Feng Wang Jingyang Luo Shiyu Fang Wenxuan Huang Yunqi Zhang Le Zhang Xiaoshi Cheng Wei Du Fang Fang Jiashun Cao Yang Wu | 2022 | Journal of Environmental Sciences2022，34，5： | 1 |
