| 1 | Microstructure and mechanical behavior of the Mg-Mn-Ce magnesium alloy sheets显示文摘The microstructural evolution and mechanical behavior of Mg-Mn-Ce magnesium alloy were investigated in the present study.Mg alloy was prepared with metal model casting method and subsequently hot extruded at 703 K with the reduction ratio of 101:1.The grains were dynamically recrystallized after the extrusion process.Moreover,the(0002)pole figure of Mg-Mn-Ce alloy developed a splitting of pronounced basal texture.The mechanical properties were different due to different angles between c-axis and loading direction(0°,45°and 90°)in the tensile tests.This significantly induces an asymmetry in the yield behavior.The Mg-Mn-Ce alloy exhibits a classical dimple structure as a result of slip accumulation and ductile tear. | Qingshan Yang Bin Jiang Xin Li Hanwu Dong Wenjun Liu Fusheng Pan | 2014 | Journal of Magnesium and Alloys2014，2，1： | 6 |
| 2 | Catalytic microwave assisted pyrolysis of aspen显示文摘The effect of catalysts on the microwave pyrolysis of aspen pellets was studied.A range of chlorides,nitrates and metal-oxides were added at 2%of the aspen mass(air dry aspen pellet weight basis).Chlorides in particular were found to favor liquid yield,especially the yield of water phase residue.Average liquid yield with added chlorides was 41%mass of the total biomass input,compared to 35%mass without catalyst.Metal-oxides were found to favor pyrolysis heavy oil,and thus total oil yield,since the yield of light oils seemed to be fairly constant.Nitrates were found to favor pyrolysis gas production.Pure light oils and light oils blended with diesel were found to be a potential diesel fuel substitute. | Johannes Moen Changyan Yang Bo Zhang Hanwu Lei Kevin Hennessy Yiqin Wan Zhiping Le Yuhuan Liu Paul Chen Roger Ruan | 2009 | International Journal of Agricultural and Biological Engineering2009，2，4： | 5 |
| 3 | Fractionation and characterization of bio-oil from microwave-assisted pyrolysis of corn stover显示文摘Bio-oil from thermochemical conversion of biomass is a complex mixture of polar and non-polar compounds,and cannot be used directly as a combustion engine fuel due to its low heating value,high viscosity,chemical instability,and incomplete volatility.Mixed-solvent extraction was developed to fractionate bio-oils from microwave-assisted pyrolysis of corn stover to produce light oil(a mixture of light and inflammable fuel oil components from bio-oil)with low viscosity and low combustion residue,and high value chemicals.Different fractions from bio-oil were characterized using GC/MS and TG,and a major chemical(hydroxy-butanedioic acid diethyl ester)was separated. | Changyan Yang Bo Zhang Johannes Moen Kevin Hennessy Yuhuan Liu Xiangyang Lin Yiqin Wan Hanwu Lei Paul Chen Roger Ruan | 2010 | International Journal of Agricultural and Biological Engineering2010，3，3： | 4 |
| 4 | Compact intense electron-beam accelerators based on high energy density liquid pulse forming lines显示文摘This paper provides a review of the compact intense electron-beam accelerators (IEBAs) based on liquid pulse forming lines (PFLs) that havebeen developed at the National University of Defense Technology (NUDT) in China. The history and roadmap of the compact IEBAs used todrive high-power microwave (HPM) devices at NUDT are reviewed. The properties of both de-ionized water and glycerin as energy storagemedia are presented. Research into the breakdown properties of liquid dielectrics and the desire to maximize energy storage have resulted in theinvention of several coaxial PFLs with different electromagnetic structures, which are detailed in this paper. These high energy density liquidPFLs have been used to increase the performance of IEBA subsystems, based on which the SPARK (Single Pulse Accelerator with spark gaps)and HEART (High Energy-density Accelerator with Repetitive Transformer) series of IEBAs were constructed. This paper also discusses howthese compact IEBAs have been used to drive typical HPM devices and concludes by summarizing the associated achievements and theconclusions that can be drawn from the results. | Jianhua Yang Zicheng Zhang Hanwu Yang Jun Zhang Jinliang Liu Yi Yin Tao Xun Xinbing Cheng Yuwei Fan Zhenxing Jin Jinchuan Ju | 2018 | Matter and Radiation at Extremes2018，3，6： | 2 |

| 8 | Processing and properties of rigid polyurethane foams based on bio-oils from microwave-assisted pyrolysis of corn stover显示文摘A new kind of rigid polyurethane(PU)foam was synthesized from the oil phase of bio-oils from microwave-assisted pyrolysis of corn stover.The recipes for the PU foams consisted of polyol-rich bio-oils,water as blowing agent,polyethylene glycol(PEG)as both polyol donor and plasticizer,diphenylmethane-4,4’-diisocyanate(polymeric MDI)as cross-linking agent,silicon-based surfactant,and tin-based catalyst.The mechanical properties of rigid foams were measured with universal testing machine(Instron4206).The effects of individual ingredients on the physical and mechanical properties of the foams were studied.It was found that water content,bio-oil content,and isocyanate dosage were important variables in making PU foams in terms of mechanical strength,density,and cellular structure Under optimal conditions,the compression strength of the prepared PU foams reached 1130 kPa with a density of 152.9 g/L.The results show that bio-oils are potential renewable polyol sources for making rigid PU foams. | Jianping Wu Yuanhua Wang Yiqin Wan Hanwu Lei Fei Yu Yuhuan Liu Paul Chen Lirong Yang Roger Ruan | 2009 | International Journal of Agricultural and Biological Engineering2009，2，1： | 0 |
