| 1 | Synthesis of condensed polynuclear aromatic resin from furfural extract oil of reduced-pressure route Ⅱ显示文摘As an industrial byproduct of oil refining,furfural extract oil from reduced-pressure route Ⅱ with high aromatic content was used to prepare heat-resistant condensed polynuclear aromatic(COPNA) resin for the first time.The basic properties of furfural extract oil and the resultant COPNA resin were characterized by infrared spectroscopy(FT-IR),nuclear magnetic resonance spectroscopy(1H-NMR),thermogravimetric analysis(TGA) and elemental analysis(EA).The result showed that heat treated furfural extract oil was successfully used for the synthesis of heat-resistant COPNA resin.The average structural parameters of raw materials and prepared resin were calculated by the improved Brown-Ladner method,and the averaged molecular structure of the resin was obtained.The reaction mechanism for the synthesis of COPNA resin was suggested as an acid-catalyzed positive ion type polymerization. | Wu Mingbo Jiang Wei Wang Yuwei Li Shibin Zheng Jingtang | 2013 | Petroleum Science2013，10，4： | 10 |
| 2 | Moving finite element methods for time fractional partial differential equations显示文摘With the aim of simulating the blow-up solutions, a moving finite element method, based on nonuniform meshes both in time and in space, is proposed in this paper to solve time fractional partial differential equations (FPDEs). The unconditional stability and convergence rates of 2-α for time and r for space are proved when the method is used for the linear time FPDEs with α-th order time derivatives. Numerical examples are provided to support the theoretical findings, and the blow-up solutions for the nonlinear FPDEs are simulated by the method. | JIANG YingJun MA JingTang | 2013 | Science China Mathematics2013，56，6： | 9 |
| 3 | Synthesis and Characterization of Condensed Polynuclear Aromatic Resin Derived from Ethylene Tar显示文摘As a kind of low-cost and readily available industrial byproduct, ethylene tar (ET) was for the first time utilized for the preparation of heat-resistant condensed polynuclear aromatic resin (COPNAR). The basic properties of ET and the resulted COPNAR were characterized by FT-IR, 1H-NMR, TGA and elemental analysis. The test results showed that ET with high aromatic content (>50%) was suitable for the synthesis of COPNAR with superior heat resistance. The average molecular structure of ET was obtained by means of the improved Brown-Ladner method, and the reaction mechanism was considered as an acid-catalyzed positive ion-typed polymerization. Our findings have provided a new route to develop ET into technology-added heat-resistant resins. | Wu Mingbo Shi Yangyang Li Shibin Wang Yuwei Tan Minghui Wang Ding Zheng Jingtang Tsubaki Noritatsu | 2012 | China Petroleum Processing & Petrochemical Technology2012，14，4： | 7 |
| 4 | Improvements of heat resistance and adhesive property of condensed poly-nuclear aromatic resin via epoxy resin modification显示文摘A bisphenol epoxy resin was used as modifier to increase the heat resistance of condensed poly-nuclear aromatic(COPNA) resin. The basic properties of COPNA resin and modified resin were characterized by Fourier transform infrared spectroscopy(FT-IR), nuclear magnetic resonance spectroscopy(1H-NMR), vapor pressure osmometry(VPO) and elemental analysis(EA). Average structural parameters of resins were calculated by the improved Brown-Ladner method, and heat resistance of resins was tested by thermogravimetric analysis(TGA). The chemical structure, mechanical properties and heat resistivity of the resin/graphite composites prepared with different resins were compared. The results show that the adhesive property and heat resistance of COPNA resin can be remarkably improved by addition of 5 wt.% epoxy resin. The reason is that the reactions between epoxy groups of epoxy resin and hydroxyl groups of COPNA resin improve the heat resistance and adhesive property of COPNA resin. Electric motor brushes with good mechanical properties and low electrical resistivity were successfully prepared by using the modified resin as binder. | Wu Mingbo Wang Yuwei Jiang Wei Li Shibin Sun Qiqian Zheng Jingtang Qiu Jieshan | 2014 | Petroleum Science2014，11，4： | 5 |

| 6 | Surface plasmon polaritons based optical directional coupler显示文摘As a basic optical device, the optical directional coupler (ODC) is basically used as optical splitters, optic switches and so on. A novel ODC employing surface plas- mon polaritons (SPPs) is proposed for high integration. The finite difference time domain (FDTD) method is adopted to simulate and analyze its properties. Results show that the ODC proposed here follows the general regulations of a conventional dielectric ODC, but its transverse size is of nanoscale, which improves the optical integration greatly. For 1550 nm and 1310 nm input wavelengths, when the coupling region length (L) equals half of its coupling length, the Excess Loss is respectively 0.57 dB and 0.56 dB, which is practical in applications. So the research on the present ODC is of some practical importance. | ZHAO HuaWei HUANG XuGuang HUANG JingTang | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，12： | 3 |
| 7 | The regulatory network behind maize seed germination: Effects of temperature, water, phytohormones, and nutrients显示文摘Seed germination is the process by which an organism grows from a seed. It requires suitable conditions and environmental factors. Maize is one of the most important crops worldwide. Germination influences both final maize yield and quality. Seed germination is regulated by a complex gene network. It is also influenced by endogenous(phytohormones and nutrients) and exogenous(temperature and water)inputs, involving molecular networks only partly identified to date. This review describes current understanding of the influence of temperature, water, phytohormones, and nutrients in regulating maize seed germination, and indicates knowledge gaps that should be addressed. | Xiaofei Xue Shangyi Du Fuchao Jiao Menghan Xi Aiguo Wang Haicheng Xu Qiqing Jiao Xin Zhang Hao Jiang Jingtang Chen Ming Wang | 2021 | The Crop Journal2021，9，4： | 2 |
