| 2 | Microstructures of metallic film and diamond growth from Fe-Ni-C system显示文摘The microstructures of metallic film surrounding diamond have been systemically studied using the transmission electron microscopy (TEM) and the atom force microscopy (AFM). The film can be divided into three layers (inner layer near diamond, external layer near graphite and middle layer). The graphite cannot be directly transformed into diamond in the film at HTHP: there exists a parallelrelationship between (111) of γ-(Fe,Ni) and (110) of Fe3C in the inner layer; the sawtooth-like step morphology found by AFM on the film is similar to that of corresponding diamond surface. A new model for diamond growth at HPHT is proposed from the parallel relationship and sawtooth-like step morphology. It is believed that Fe3C may be a transitional phase in the course of diamond growth, γ-(Fe,Ni) in the inner layer can absorb carbon atom groups with lamella structure from Fe3C, and then the carbon groups stack on growing diamond. | XU Bin LI Musen YIN Longwei CUI Jianjun LIU Yuxian GONG Jianhong | 2002 | Chinese Science Bulletin2002，47，15： | 12 |
| 3 | Recent advances in carbon dioxide capture and utilization with amines and ionic liquids显示文摘Global warming and climate change due to anthropogenic carbon dioxide(CO_(2))have aroused significant concerns at the global scale due to rapid economic growth in industries and other fields.Therefore,CO_(2)capture,use,and storage have become particularly important.In this review,general background and methods for CO_(2)capture and separation,in particular,on ionic liquids(ILs)-based solvents and materials,are discussed.Comprehensive surveys of ILs for CO_(2)absorption are presented,which focused mainly on experimental researches,and then the concept is extended to functionalized absorbents and recent developments for CO_(2)capture.Major advantages and disadvantages of amines-based and ILs-based absorbents are discussed in this review.Solutions of traditional amines(MEA,MDEA,DEA,AMP,PZ,etc.)and ILs(conventional ILs,functionalized ILs,etc.)are summarized.Moreover,research progresses on CO_(2)separation are also introduced focusing mainly on amines and ILs-based membranes(e.g.supported amines membranes,SILMs).Futhermore,the fixation of CO_(2)into cyclic carbonates catalyzed by ILs(pure ILs,complex catalyst system with ILs,supported ILs,etc.)is summarized,clearly explaining the mechanism of CO_(2)fixation with ILs.Finally,exploration of some recent studies about CO_(2)capture and conversion by ILs and challenges for further progress are presented and related suggestions are put forward. | Yuxin Wu Jianhong Xu Kathryn Mumford Geoffrey W.Stevens Weiyang Fei Yundong Wang | 2020 | Green Chemical Engineering2020，1，1： | 9 |
| 4 | Perchlorate removal using granular activated carbon supported iron compounds: Synthesis, characterization and reactivity显示文摘Synthesis and use of the iron compounds supported on granular activated carbon (ICs/GAC) have shown significant environmental implications for perchlorate (ClO 4 ) removal. ICs/GAC was synthesized via hydrolyzing FeSO 4 ·7H 2 O on GAC, reduced by NaBH 4 solution in polyethylene glycol 6000 and ethanol solution, dried in vacuum condition and exposed to air. Synthesized ICs/GAC was characterized using transmission electron micrograph (TEM), Brunauer-Emmett-Teller, X-ray photoelectron spectroscopy (XPS). ICs/GAC was determined to be containing a large amount of FeOHSO 4 , Fe 2 O 3 and a small amount of zero-valent iron (ZVI) nanoparticles according to TEM and XPS measurements. Batch static kinetic tests showed that 97% of ClO 4 was removed within 10 hr at 90°C and 86% of ClO 4 was removed within 12 hr at 25°C, at ICs/GAC dosage of 20 g/L. The experimental results also showed that FeOHSO 4 and Fe 2 O 3 nanoparticles have the function of perchlorate adsorption and play important roles in ClO 4 removal. The activation energy (E a ) was determined to be 9.56 kJ/mol. | Jianhong Xu Naiyun Gao Yulin Tang Yang Deng Minhao Sui | 2010 | Journal of Environmental Sciences2010，22，11： | 8 |
| 5 | Flexibility of MIP Technology显示文摘The flexibility of MIP technology to meet market demand is mainly introduced in this study. Their commercial application and technical principle are analyzed too. The MIP technology with wide feed adaptability can form a good combination with other technologies. The MIP technology has been applied extensively in China. Based on this platform, the CGP, MIP-LTG and MIP-DCR technologies have been developed, which can further improve the flexibility of MIP technology. Based on its novel reaction control technique with a sole sequential two-zone riser, the MIP users can easily switch to different operating modes between producing either more clean gasoline and propylene or diesel through changing the catalysts and varying the operating conditions. That offers MIP users with enough production flexibility and a rational production arrangement to meet the market demand. The MIP-DCR technology with less dry gas and coke yields can provide a more flexible operating mode since the catalysts to oil ratio has become an independent variable. | Tang Jinlian Gong Jianhong Xu Youhao | 2015 | China Petroleum Processing & Petrochemical Technology2015，17，3： | 8 |
| 6 | Metabolomics mechanism of traditional soy sauce associated with fermentation time显示文摘Given that fermentation time has significant impact on quality and flavor of soy sauce,a global understanding of the metabolic mechanism as fermentation time prolonged is essential for producing satisfactory and consistent quality of traditional soy sauce.Herein,the metabolic compounds changes of soy sauce associated with fermentation time up to 10 years were comprehensively investigated by using Chinese traditional fermented soy sauce(CTFSS)as a demonstration.Results showed that formaldehyde nitrogen,total soluble nitrogen(TSN),non-salt soluble solids,amino acids,free 5’-nucleotides and volatile compounds in CTFSS changed obviously during fermentation.Specifically,glutamic acid and aspartic acid were prominent in CTFSS.Continuous decrease in content of hypoxanthine(Hx)was found from 1 M(1-month soy sauce)to7 M(7-months soy sauce).Furthermore,a significant opposite tendency for changes between some volatile compounds and amino acids was indicated that there was a transformation between these two components.Therefore,a better understanding to the influence of fermentation time on soy sauce had been proposed.As the formation and conversion of amino acids and sugars might be mainly responsible for flavor formation in CTFSS,the ratio of these two reactions rate led the metabolism to be divided into three steps,degradation,conversion and balance. | Li Zhu Siyu He Ying Lu Jianhong Gan Ningping Tao Xichang Wang Zaoli Jiang Yuanxiang Hong Changhua Xu | 2022 | Food Science and Human Wellness2022，11，2： | 7 |

We believe that the review will contribute to the readers in this prospective area very well. | XuehuiGe Hong Zhao Tao Wang Jian Chen Jianhong Xu Guangsheng Luo | 2016 | Chinese Journal of Chemical Engineering2016，24，6： | 7 |
| 8 | Synergetic Effect of Y Zeolite and ZSM-5 Zeolite Ratios on Cracking, Oligomerization and Hydrogen Transfer Reactions显示文摘The objective of this study is to explore the optimum composition of Y and ZSM-5 zeolites to develop novel catalysts for obtaining lower gasoline olefins content and higher propylene yield. Five composite zeolite catalysts with varying Y zeolite/ZSM-5 zeolite ratios have been prepared in this work to investigate the synergy between the Y zeolite and ZSM-5 zeolite on the selectivity to protolytic cracking, β-scission, oligomerization, and hydrogen transfer reactions using a FCC naphtha feedstock at 480 ℃ in a confined fluidized bed reactor. Experimental results showed that the composite catalyst with a Y zeolite/ZSM-5 zeolite ratio of 1:4 had the highest protolytic cracking and β-scission ability, which was even higher than that of pure ZSM-5 catalyst. On the other hand, the catalyst with a Y zeolite/ZSM-5 zeolite ratio of 3:2 exhibited the strongest hydrogen transfer functionality while the pure Y zeolite based catalyst had the highest oligomerization ability. For all the catalysts tested, increasing conversion enhanced the selectivity to protolytic cracking and hydrogen transfer reactions but reduced the selectivity to β-scission reaction. However, no clear trend was identified for the selectivity to oligomerization when an increased conversion was experienced. | Gong Jianhong Xu Youhao Long Jun Wei Xiaoli | 2014 | China Petroleum Processing & Petrochemical Technology2014，16，3： | 7 |
| 9 | Preparation and ion exchange properties of egg-shell glass beads with different surface morphologies显示文摘A subcritical water treatment method was developed for preparing porous-surfaced glass beads with an egg-shell structure in a batch reactor. Based on the 'corrosion-ion-migration-recondensation' strategy, ordinary soda-lime glass beads with a diameter of about 100 m were made first to react with subcritical water to effect controlled quantity of silicate dissolution of glass by adjusting treatment time and temperature. The dissolved silicate was then made to recondense on the glass core to form different porous shell morphologies: pores, flakes and fibers. Among these, glass beads coated with fibers with surface area of 154.5 m2/g, pore volume of 0.27 cm3/g and pore size of 7.1 nm were obtained at 573 K after 2 h of treatment. The prepared porous-surfaced glass beads were then used as adsorbent for heavy metal ions, showing various ion exchange properties. Glass beads covered with fibers displayed fast kinetics and high sorption capacity because of their egg-shell structure and high surface area. More than 90% of copper ions were adsorbed within 100 min from a solution with an initial concentration of 110 mg/L at 313 K. Ion sorption capacities were 149.33, 81.33 and 42.96 mg/g respectively for Ag+, Cu2+ and Ni2+ at 313 K. A green and low-cost method was thus developed to produce egg-shell-structured porous glass with high sorption capacity. | Chun Shen Yujun Wang Jianhong Xu Yangcheng Lu Guangsheng Luo | 2012 | Particuology2012，10，3： | 6 |

| 13 | A novel approach to study the interactions between polymeric stabilized micron-sized oil droplets by optical tweezers显示文摘The well understanding of interaction forces between single dispersed droplets is crucial to the understanding of emulsion stabilization mechanism.Recently,many studies have reported the direct quantitative measurements of interaction forces between 20-200μm single droplet coated polymers by atomic force microscope(AFM).These studies have revealed many important results about the relationship of the interaction forces and the droplet deformation.However,these studies of the quantitative relationship between the measured interaction forces and the separation distance of the front end of the droplet have rarely been reported.Optical tweezer instrument can make it possible to establish the quantitative relationship between the measured force and the separation distance of the front end of the droplet,which will make better understanding of the interaction mechanisms between droplets.Due to the differences of the measuring mechanism between atomic force microscopy(AFM)and optical tweezers,the theory model of AFM measurements cannot be fitted with the force measurement by optical tweezers.We have made an exhaustive comparison of the measuring differences between AFM and optical tweezer instrument in this work.Moreover,we built a numerical model to derive the repulsive pressure through the measured force curve in order to quantify the measured force of two micron-sized oil droplet coated polymers by optical tweezers.Furthermore,the novel method can be extended to other micron-sized emulsion systems,and these findings will be a vital progress on quantitative force measurements between micron-sized droplets. | An Chen Shaowei Li Jianhong Xu | 2020 | Chinese Journal of Chemical Engineering2020，28，5： | 3 |
| 14 | Efficient fixation of CO_(2) into propylene carbonate with [BMIM]Br in a continuous-flow microreaction system显示文摘Utilization of carbon dioxide(CO_(2)) is of great significance in the development of CO_(2) absorption and the solution of greenhouse gas effect.Highly efficient conversion of CO_(2) into cyclic carbonate with green catalysts is essential for the more sustainable expansion of CO_(2) fixation.Traditional batch reactor is limited by low efficiency, high cost and low security. Meanwhile, continuous flow system showcased a myriad of virtues, including shortening the residence time from hours to seconds, and decreasing reaction temperature, and possessing the nature of easy industrial scale-up. In this paper, a continuous-flow microreaction system was developed to synthesis propylene carbonate(PC) from propylene oxide(PO) and CO_(2) using 1-butyl-3-methylimidazolium bromide([BMIM]Br) as catalyst. By observing the flow patterns inside microreaction system, the effects of reaction temperature, molar fraction of catalyst, operating pressure, residence time, molar ratio of CO_(2)/PO as well as recycling performance of catalyst on the overall performances were comprehensively evaluated into details. Under different reaction conditions,the flow patterns were set to vary between slug flow and annular flow. The results showed that the yield of propylene carbonate(PC) can reach99.7% at 140℃ and 3.0 MPa with the residence time of 166 s, while the recycling performance of the designed system greatly conforms the future trend of green chemistry. | Yuxin Wu Yuncheng Ding Jianhong Xu Yundong Wang Kathryn Mumford Geoffrey WStevens Weiyang Fei | 2021 | Green Energy & Environment2021，6，2： | 3 |
| 15 | Effects of heat treatment on mechanical properties and microstructure of tungsten fiber reinforced grey cast iron matrix composites显示文摘In this study,grey cast iron matrix composites reinforced by different volume fractions of tungsten fibers(Vr=0.95%,1.90%,2.85%,3.80%)were investigated in as-cast and under the heat treatment temperatures of 1,000℃and 1,100℃.The microstructure and mechanical properties of the composites were analyzed and tested by means of SEM,micro-hardness tester and three-point bend testing.The results show that with increasing of the volume fraction of tungsten fibers,the composites reinforced by the tungsten fiber have higher flexural strength and modulus than that of cast iron without reinforcement,and the flexural strength increases with the increasing of heat treatment temperatures.Due to diffusion reaction between matrix and reinforcing phases,the process of heat treatment,the number of graphite flakes in the matrix seemingly becomes lower;and some hard carbide particles are formed around the residual tungsten fibers.Not only does the hardness of both matrix and reinforcement change tremendously,but also the region of reinforcement is also extended from the original 0.11 mm to 0.19 mm in radius. | Niu Libin Xu Yunhua Peng jianHong Wu Hong | 2009 | China Foundry2009，6，4： | 3 |
| 16 | Large-eddy simulation of the compressible flow past a tabbed cylinder显示文摘The compressible flow past a tabbed cylinder has been studied numerically using large-eddy simulation for a free-stream Mach number M∞=0.75 and a Reynolds number based on the diameter Re=2×105. Because of the passive control of the flow past a tabbed cylinder, the mean drag coefficient of tabbed cylinder is less than that of a corresponding circular cylinder with a drag reduction up to 33%. The fluctuating lift coefficient is greatly suppressed to be nearly zero. Drag reduction due to the shearing process prevails over that due to the compressing process in this flow. Through investigating the mechanisms relevant to passive control of the tab, it is found that suppression of the shear layer instability can lead to a higher-base-pressure distribution, which can reasonably be associated with drag reduction and suppression of the lift fluctuations. The analysis of convective Mach number and self-sustained oscillations phenomenon inside the shear layers indicates that both the compressible effect and high-frequency forcing result in suppression of the shear layer instability of tabbed cylinder. | XU ChangYue ZHAO LiQing SUN JianHong | 2012 | Chinese Science Bulletin2012，57，24： | 3 |

| 18 | A pseudo-coupled numerical approach for stability analysis of frozen soil slopes based on finite element limit analysis method显示文摘To simplify the stability analysis of frozen soil slope, a pseudo-coupled numerical approach is developed. In this approach, the coupled heat transfer and water flow in frozen soils are simulated first, and based on the computed thermal-hydro field, the stability of frozen soil slope is evaluated. Although the shear strength for frozen soil is very complicated and is usually represented by a nonlinear MC failure criterion, a simple linear MC yield criterion is utilized. In this method, the internal friction angle is expressed as a function of volumetric ice content and the cohesion is fitted as a simple bilinear expression of T and volumetric water content. To assess slope stability, the limit analysis is employed in conjunction with the recently developed α-section search algorithm. A frozen soil slope example is used to examine the proposed pseudo-coupled numerical approach, and numerical studies validate its effectiveness. Based on numerical results, it is seen that slope stability may be remarkably influenced by warming air (or ground surface) temperature. With increasing ground surface temperature, slope stability indicated by FOS may reduce to 1.0, implying that warming air temperature could be a trigger of frozen soil slope failure. | Xi Chen JianKun Liu Yuan Feng Xu Li YaHu Tian JianHong Fang | 2013 | Research in Cold and Arid Regions2013，5，4： | 3 |

| 20 | Rapid Microwave-Assisted Ionothermal Dissolution of Cellulose and Its Regeneration Properties显示文摘Introduction of the strategy of anhydrous calcium carbonate protection incorporated with the drop by drop reaction,high-purity 1-butyl-3-methylimidazolium chloride([Bmim]Cl)was prepared at reaction temperature of 80°C for only 10 h.Cellulose samples from different biomass sources(with different degree of polymerization characteristic)could be rapidly(no more than 10 minutes)and completely dissolved in the[Bmim]Cl using a microwave-assisted ionothermal route.Homogeneous cellulosic regenerates with high degree of polymerization and thermal stability characteristics were obtained through a coagulation process in water.Furthermore,the dissolved celluloses were readily regenerated into solid products such as casting films and spinning fibers,which exhibited high transparency and flexibility,as well as superior mechanical properties of over 300 MPa(tensile strength)more than those of cellulose samples reported.This study therefore provides a new process for the synthesis of high-purity[Bmim]Cl for the highly efficient dissolution of cellulose to produce high performance cellulosic materials for various applications such as flexible electronic,optoelectronic,soft robots. | Xu Wang Jianhong Zhou Bo Pang Dawei Zhao | 2019 | Journal of Renewable Materials2019，7，12： | 2 |
