| 1 | Color stability of FCC gasoline显示文摘The color changes of one representative FCC gasoline were studied. The red substance in the FCC gasoline was concentrated and separated by chromatography and analyzed by elemental analysis and gas chromatography-mass spectrometry (GC-MS). The main components of the red substance were found to be aromatic amines. Complexes formed from quinones and aromatic amines are the reason why gasoline being red, and acids can destroy the complex by reaction with aromatic amines leading to decoloration of red gasoline. A mechanism for the color change of gasoline is proposed. | Song Lechun Li Peibo Lu Liang Chen Jihai Zhou Yulu Xiang Yuzhi Xia Daohong | 2012 | Petroleum Science2012，9，2： | 2 |

| 3 | Toxicity Test of Different Pesticides on Tobacco Root-knot Nematodes显示文摘[Objectives]This study was conducted to quickly screen out effective and safe agents for controlling tobacco root knot nematode disease.[Methods]Six pesticides were tested and screened indoors at five different concentrations.[Results]The six pesticides all had toxic effects on the second-instar larvae of tobacco root-knot nematode,and the corrected mortality was positively correlated with the concentration and time of the pesticides,with the correlation coefficients above 0.8.From the perspective of inhibitory activity,the order was fosthiazate>abamectin>emamectin benzoate>cadusafos>ethoprophos>carbosulfan.Four pesticides that can be used in the field were selected.[Conclusions]This study provides a theoretical basis for field pesticide selection. | Fei DAI Peibo LI Quan ZHANG Enfa CHEN | 2020 | Agricultural Biotechnology2020，9，5： | 1 |
| 4 | A novel breathable flexible metallized fabric for wearable heating device with flame-retardant and antibacterial properties显示文摘Currently,there is an imperative demand for developing a novel flexible heater with high adhesion,breathability,and extreme condition resistance,such as ultra-high temperatures and even fire.Herein,a high-adhesion,flame-retardancy,and anti-bacteria copper nanoparticles networks/nylon 6 woven fabric(CNNs/NWF)wearable heater with a“sandwich-like”structure has been designed and fabricated based on phatic acid/aminopropyltriethoxysilane(PA/APTES)hybrid coating.On the one hand,the CNNs/NWF wearable heater exhibited superb electrothermal behavior working at a peak temperature of 208.8℃powered with 2.0 V,better than that of wearable heaters in the recently reported literature.On the other hand,the vertical burning test showed that the heater possesses splendid flame retardancy.Furthermore,the PA/APTES coating could deposit a nanoscale porous protective film on the surface of CNNs/NWF,which imparts the heater with relatively excellent oxidation resistance and breathability.In addition,the antibacterial efficiency against Escherichia coli(E.coli)and Staphylococcus aureus(S.aureus)still reached100%after 50 times of standard washing and being electrified at 2.0 V for 5 min,keeping humans away from the threat of bacterial infections.We think that the heater in this research could be extended to wearable heating devices. | Peibo Du Jinping Zhang Zhiguang Guo Helan Wang Zhenmeng Luo Zhiying Fan Bo Li Zaisheng Cai Fengyan Ge | 2022 | Journal of Materials Science & Technology2022，，27： | 1 |

| 6 | Elastic Model of Flexure-Based Linkage under Motion Constrains and External Load显示文摘For a flexible mechanism with several-stage flexible linkage, the flexible linkage is equivalent to work under the actions of an external load and motion constrains. This paper aims to deal with a simplified elastic model on the kinematic characteristics of a flexure-based linkage under these conditions. The elastic modeling method was developed based on motion constrains and the elastic beam theorem(EBT). Effects of a constant force, an elastic force with a constant stiffness, and the materials were taken into account. The proposed modeling method was verified by comparing with the finite element method(FEM). Further, the developed modeling method was used to optimize a flexure-based mechanism based on a two-stage flexible linkage to realize a maximum displacement amplification ratio of 6.56. The flexure-based mechanism was employed to drive a miniature sucker, which performed with a negative pressure of 2.45 kPa at a frequency of 13.2 kHz. | Peibo Li Jihao Liu Tianzi Zhao Helei Zhu Yanzheng Zhao | 2021 | Journal of Harbin Institute of Technology(New Series)2021，28，3： | 0 |
| 7 | Review of atomization mechanism and spray characteristics of a liquid jet in supersonic crossflow显示文摘The injection and atomization process of a liquid fuel jet is critical for an ignition start of a scramjet engine.Airwall-mounted crossflow injection strategy is widely used in scramjet combustors,avoiding high total pressure loss and allowing the liquid fuel to rapidly undergo atomization,mixing,and evaporation.In this review,research progress on a liquid jet in supersonic crossflow was evaluated from aspects of atomization mechanism and spray characteristics.When a liquid jet is injected into a supersonic crossflow,primary and secondary breakups occur successively.The surface instability of liquid can significantly affect the breakup process.This review discusses the current understanding of the breakup process and spray characteristics of a liquid jet in supersonic crossflow including the mechanism of atomization and the characteristics of distribution and atomization.The development of windward Rayleigh-Taylor(R-T)unstable waves is the main factor in column breakup.The development of Kelvin-Helmholtz(K-H)unstable waves along the circumferential direction of the jet or droplets is the main factor of surface and droplet breakups.The liquid-gas momentum ratio is the most important factor affecting the penetration depth.The span width of the liquid jet is affected by the windward area.Breakup and coalescence lead to a transformation of the size distribution of droplets from S-or C-shaped to I-shaped,and the velocity distribution of the droplets on the central symmetry plane has a mirrored S-shape.The droplet distribution on the spanwise cross-section retains a structure similar to an“Ω”shape.At last,some promising recommendations have been proposed,namely a theoretical predictive model which can describe the breakup mechanism of a liquid jet,the distribution characteristics and droplets size distribution of a liquid jet under a cavity combustion chamber,especially for enthalpy flows with complex wave structures. | Yaozhi ZHOU Zun CAI Qinglian LI Chenyang LI Mingbo SUN Peibo LI Hongbo WANG | 2023 | Chinese Journal of Aeronautics2023，36，8： | 0 |
