| 1 | Arrangement models of alkylammonium cations in the interlayer of HDTMA^+pillared montmorillonites显示文摘The orientation of HDTMA+ in the interlayer of organic pillared montmorillonites prepared at different concentrations of HDTMA+ have been studied using X-ray powder diffraction (XRD) and theoretical calculation. A series of arrangement models of HDTMA+ in the interlayer of montmorillonite have been proposed as lateral-monolayer (LM), lateral-bilayer (LB), pseudotrilayer (PT), paraf-fin-type-monolayer (PM), paraffin-type-bilayer (PB). With the increase of the concentration of HDTMA+, the arrange-ment model of HDTMA+ in the interlayer of montmorillo-nites changes as lateral-monolayer→lateral-bilayer→para- ffin-type monolayer→pseudotrilayer→paraffin-type-bilayer and the packing density of HDTMA+ in the interlayer in-creases gradually. In the intermediate stages, different mod-els may coexist. | ZHU Jianxi, HE Hongping, GUO Jiugao, YANG Dan & XIE Xiande Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, China Correspondence should be addressed to He Hongping | 2003 | Chinese Science Bulletin2003，48，4： | 16 |
| 2 | Synthesis, characterization and size control of zerovalent iron nanoparticles anchored on montmorillonite显示文摘Zerovalent iron nanoparticles have been successfully synthesized using sodium borohydride solution reduction of ferric trichloride hexahydrate in the presence of montmorillonite as an effective protective reagent and support as well. A combination of characterizations reveals that with high monodispersity these obtained iron nanoparticles are well dispersed on clay surface, virginal from boron related impurity, and oxidation resistant well with iron core-iron oxide shell structure. The shell thickness of 3 nm remains almost invariable under ambient conditions. The size control of these iron nanoparticles has been achieved by tailoring the amount of the ferric iron, which mainly depends on the protective action of montmorillonite. | FAN MingDe YUAN Peng CHEN TianHu HE HongPing YUAN AiHua CHEN KangMin ZHU JianXi LIU Dong | 2010 | Chinese Science Bulletin2010，55，11： | 15 |

| 4 | Mechanism of the interaction between Au nano-particles and polymerase in nanoparticle PCR显示文摘Nanoparticle PCR is a novel method to optimize DNA amplification. It performs well in improving specificity, enhancing sensitivity and speed. Several mechanisms were proposed in previous studies: one was based on the interaction between gold nanoparticles (AuNPs) and DNA while the other was attributed to the heat transfer property of AuNPs. In this paper, we propose that the interaction between AuNPs and DNA polymerase can significantly influence PCR. First, the addition of DNA polymerase can eliminate the inhibitory effects of excess AuNPs. Second, the addition of AuNPs will increase yield of the desired PCR product and make the optimum concentration of DNA polymerase move to higher value. Third, while excess polymerase might inhibit amplification efficiency, AuNPs can reverse this process and the yield of PCR amplification. Based on these results we propose a possible mechanism that AuNPs might modulate the activity of polymerase and improve PCR amplification. | MI LiJuan ZHU HongPing ZHANG XiaoDong HU Jun FAN ChunHai | 2007 | Chinese Science Bulletin2007，52，17： | 7 |
| 5 | Finite Element Model Updating of Bridge Structures Based on Sensitivity Analysis and Optimization Algorithm显示文摘The dynamic characteristics of bridge structures, such as the natural frequencies, mode shapes and model damping ratio, are the basis of structural dynamic computation, seismic analysis, vibration control and structural health condition monitoring. In this paper, a three-dimensional finite-element model is established for a highway bridge over a railway on No.312 National Highway and the ambient test is carried out in site, the dynamic characteristics of the bridge are studied using the finite-element analysis and ambient vibration measurements. Comparison between the theoretical and experimental results shows that the frequency differences of the modes range between 0.44% and 8.77%. If the measurement is more reliable, the finite element model updating is necessary. Thus, a set of de- sign variables is selected based on sensitivity analysis, then the finite ele- ment model of the bridge is updated based on optimization algorithm. The results of model updating show that the proposed updating method in this paper is more simple and effective, the updated finite element model can reflect the dynamic characteristics of the bridge better, the analytical results can provide the theoretical basis for damage identification and health con- dition monitoring of the bridge. | HUANG Minshui ZHU Hongping | 2008 | Wuhan University Journal of Natural Sciences2008，13，1： | 6 |
| 6 | Heterogeneous Fracture Simulation of Three-point Bending Plain-concrete Beam with Double Notches显示文摘Plain concrete is regarded as a two-phase material comprising randomly distributed aggregates and mortar matrix. A series of three-point bending concrete beams with symmetric or asymmetric double notches are modeled using the modified random aggregate generation and packing algorithm. The cohesive zone model is used as the fracture criterion and the cohesive elements are inserted into both the mortar matrix and the aggregate-mortar interfaces as potential micro-cracking zones. The dead and alive crack phenomena are studied experimentally and numerically; and the influences of notch location, aggregate distribution and gradation on fracture are numerically evaluated. Some important conclusions are given. | Chuanchuan Zhang Xinhua Yang Hu Gao Hongping Zhu | 2016 | Acta Mechanica Solida Sinica2016，29，3： | 6 |
| 7 | Preparation and characterization of 3-aminopropyl-triethoxysilane grafted montmorillonite and acid-activated montmorillonite显示文摘3-aminopropyltriethoxysilane grafted montmorillonites were synthesized with montmorillonite, acidactivated montmorillonites and 3-aminopropyltriethoxysilane in ethanol-water mixture. The resulting products were investigated using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), thermogravimetric analysis (TG). XRD patterns demonstrated that silane was intercalated into the montmorillonite gallery, indicated by increasing basal spacings. These intercalated silanes probably adopt bilayer arrangement models within the montmorillonite and acid-activated montmorillonites interlayer spaces. TG and DTG curves indicate that acidification results in a decrease of the thermal stability of the resultant montmorillonites. Silane grafting leads to a surface property transformation of montmorillonite from hydrophilicity to lipophilicity and an increase of the thermal stability of the condensed silanes. | SHEN Wei HE HongPing ZHU JianXi YUAN Peng MA YueHong LIANG XiaoLiang | 2009 | Chinese Science Bulletin2009，54，2： | 6 |
| 8 | Polyoxometalate-based silica-supported ionic liquids for heterogeneous oxidative desulfurization in fuels显示文摘With the aim of deep desulfurization, silica-supported polyoxometalate-based ionic liquids were successfully prepared by a one-pot hydrothermal process and employed in heterogeneous oxidative desulfurization of various sulfur compounds. The compositions and structures of the hybrid samples were characterized by various methods such as FT-IR, XPS, Raman,UV–Vis, wide-angle XRD and N_2 adsorption–desorption. The experimental results indicated that the hybrid materials presented a high dispersion of tungsten species and excellent catalytic activity for the removal of 4,6-dimethyldibenzothiophene without any organic solvent as extractant, and the sulfur removal could reach 100.0% under mild conditions.The catalytic performance on various substrates was also investigated in detail. After cycling seven cycles, the sulfur removal of the heterogeneous system still reached 93.0%. The GC-MS analysis results demonstrated that the sulfur compound was first adsorbed by the catalyst and subsequently oxidized to its corresponding sulfone. | Ming Zhang Miao Wang Jiapeng Yang Hongping Li Jiaqi Liu Xiao Chen Wenshuai Zhu Huaming Li | 2018 | Petroleum Science2018，15，4： | 5 |
| 9 | Interaction of polyhydroxy fullerenes with ferrihydrite:adsorption and aggregation显示文摘The rapid development of nanoscience and nanotechnology, with thousands types of nanomaterials being produced, will lead to various environmental impacts. Thus,understanding the behaviors and fate of these nanomaterials is essential. This study focused on the interaction between polyhydroxy fullerenes(PHF) and ferrihydrite(Fh), a widespread iron(oxyhydr)oxide nanomineral and geosorbent. Our results showed that PHF were effectively adsorbed by Fh. The adsorption isotherm fitted the D-R model well, with an adsorption capacity of 67.1 mg/g. The adsorption mean free energy of 10.72 k J/mol suggested that PHF were chemisorbed on Fh. An increase in the solution p H and a decrease of the Fh surface zeta potential were observed after the adsorption of PHF on Fh; moreover, increasing initial solution p H led to a reduction of adsorption. The Fourier transform infrared spectra detected a red shift of C–O stretching from 1075 to 1062 cm-1 and a decrease of Fe–O bending, implying the interaction between PHF oxygenic functional groups and Fh surface hydroxyls. On the other hand, PHF affected the aggregation and reactivity of Fh by changing its surface physicochemical properties. Aggregation of PHF and Fh with individual particle sizes increasing from 2 nm to larger than 5 nm was measured by atomic force microscopy. The uniform distribution of C and Fe suggested that the aggregates of Fh were possibly bridged by PHF. Our results indicated that the interaction between PHF and Fh could evidently influence the migration of PHF, as well as the aggregation and reactivity of Fh. | Jing Liu Runliang Zhu Tianyuan Xu Mingwang Laipan Yanping Zhu Qing Zhou Jianxi Zhu Hongping He | 2018 | Journal of Environmental Sciences2018，30，2： | 5 |
| 10 | TiO_2/Schwertmannite nanocomposites as superior co-catalysts in heterogeneous photo-Fenton process显示文摘The heterogeneous photo-Fenton reaction is an effective technique in combating organic contaminants for both soil and water remediation,and extensive studies have focused on enhancing its efficiency and reducing its costs.In this work,we developed novel photoFenton catalysts by simply milling commercially available TiO_2(P25)with Schwertmannite(Sh),a natural iron-oxyhydroxysulfate nanomineral.We expect that the photo-generated electrons from TiO_2could continuously migrate to Sh,which then could enhance the separation of electron-hole pairs on TiO_2and accelerate the reduction of Fe(III)to Fe(II)on Sh,leading to high degradation efficiency of the target organic contaminants.SEM and TEM results showed the distribution of TiO_2on Sh surface for the nanocomposites(TiO_2/Sh).Under simulated sunlight irradiation,the much higher content of Fe(II)was determined on TiO_2/Sh than on Sh via a common method in the iron ore,and the consumption of H_2O_2and the production of·OH were more significant in the TiO_2/Sh system than those in the TiO_2and Sh systems.These results well support our hypothesis that the photo-generated electrons could migrate from TiO_2to Sh on the composites,and can also explain the much higher degradation efficiency of Rhodamine B(RhB)in the TiO_2/Sh system.Besides,TiO_2/Sh had lower Fe dissolution as compared with Sh,and retained high catalytic stability after four repeated cycles.Above merits of the TiO_2/Sh composites,in combining with their simple synthesis method and low-cost property,indicated that they should have promising applications as heterogeneous photo-Fenton catalysts. | Yanping Zhu Chun Zeng Runliang Zhu Yin Xu Xingyan Wang Huijun Zhou Jianxi Zhu Hongping He | 2019 | Journal of Environmental Sciences2019，31，6： | 5 |
| 11 | Amorphous TiO_2-supported Keggin-type ionic liquid catalyst catalytic oxidation of dibenzothiophene in diesel显示文摘Supported ionic liquid(IL) catalysts [C_nmim]_3PMo_(12)O_(40)/Am TiO_2(amorphous TiO_2) were synthesized through a one-step method for extraction coupled catalytic oxidative desulfurization(ECODS) system. Characterizations such as FTIR, DRS,wide-angle XRD, N_2 adsorption–desorption and XPS were applied to analyze the morphology and Keggin structure of the catalysts. In ECODS with hydrogen peroxide as the oxidant, it was found that ILs with longer alkyl chains in the cationic moiety had a better effect on the removal of dibenzothiophene. The desulfurization could reach 100% under optimal conditions, and GC–MS analysis was employed to detect the oxidized product after the reaction. Factors affecting the desulfurization efficiencies were discussed, and a possible mechanism was proposed. In addition, cyclic experiments were also conducted to investigate the recyclability of the supported catalyst. The catalytic activity of [C_(16)mim]_3 PMo_(12)O_(40)/Am TiO_2 only dropped from 100% to 92.9% after ten cycles, demonstrating the good recycling performance of the catalyst and its potential industrial application. | Zhendong Yu Donghui Wang Suhang Xun Minqiang He Ruliang Ma Wei Jiang Hongping Li Wenshuai Zhu Huaming Li | 2018 | Petroleum Science2018，15，4： | 3 |
| 12 | SDS-PAGE study on photooxidation damage of lysozyme induced by riboflavin显示文摘The photooxidation damage of lysozyme under 315-375 nm irradiation in the presence of riboflavin was studied by using sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE).Indica- tions showed that the mechanisms and products of oxidative damage were relative to the concentra- tion of riboflavin,the time of irradiation and the ambience.The type I process was examined in a nitrogen saturated solution,whereas both type I and type II were observed in an aerobic atmosphere and type II was the dominant process.The study also suggested that antioxidants,such as melatonin, can reduce the damage of lysozyme effectively. | ZHANG ZhaoXia ZHAO HongWei ZHU HongPing GE Min WANG WenFeng YAO SiDe LI WenXin | 2007 | Science China Chemistry2007，50，1： | 3 |
| 13 | A comparative study of the extractive desulfurization mechanism by Cu(Ⅱ)and Zn-based imidazolium ionic liquids显示文摘A comparative study of the extractive desulfurization(EDS) mechanism by Cu(Ⅱ) and Zn-based ILs([C_4mim]_2[MCl_4], M ? Cu(Ⅱ) or Zn)has been performed. It is found that the p–p interaction and C-H/p interaction play important roles in EDS for both Cu(Ⅱ) and Zn-based ILs,which is different from Al, Fe-based ILs. In the gas phase models, the interaction energy between Zn-based ILs and dibenzothiophene(DBT) is stronger than the interaction energy of Cu(Ⅱ)-based ILs. In order to consider the solvent effect, a generic ionic liquid of solvation model has been implemented, which is few considered in the previous calculations of EDS. It is interesting to find that the gap of interaction energies between Cu(Ⅱ), Zn-based ILs and DBT are reduced when the solvent effect is considered. In addition, by combined discussion of currently theoretical and experimental evidences for metal-based ILs with different compositions, we firstly propose that the EDS performance should be influenced by the balance of the contribution of cation, metal-based anion, metal chlorides and the viscosity. | Hongping Li Beibei Zhang Wei Jiang Wenshuai Zhu Ming Zhang Chao Wang Jingyu Pang Huaming Li | 2019 | Green Energy & Environment2019，4，1： | 2 |

| 15 | Surgical treatment of hepato-pancreato-biliary disease in China:the Tongji experience显示文摘Hepato-pancreato-biliary(HPB) tumors are common in China. However, these tumors are often diagnosed at intermediate/advanced stages because of the lack of a systemic surveillance program in China. This situation creates many technical challenges for surgeons and increases the incidence of postoperative complications. Therefore, Dr. Xiao-Ping Chen has made many important technical improvements, such as Chen's hepatic portal occlusion method, the anterior approach for liver resection of large HCC tumors, the modified technique of Belghiti's liver-hanging maneuver, inserting biliary-enteric anastomosis technique, and invaginated pancreaticojujunostomy with transpancreatic U-sutures. These techniques are simple, practical, and easy to learn. Owing to these advantages, complicated surgical procedures can be simplified, and the curative effects are greatly improved. These improved techniques have been widely applied in China and will benefit many additional patients. In this review, we introduce our experience of surgically treating intermediate/advanced hepatocellular carcinoma(HCC), hilar cholangiocarcinoma(HC), and pancreatic carcinoma, mainly focusing on technical innovations established by Dr. Chen in HPB surgery. | binhao zhang wei dong hongping luo xuanru zhu lin chen changhai li wei zhang shuai xiang wanguang zhang zhiyong huang xiao-ping chen | 2016 | Science China(Life Sciences)2016，59，10： | 2 |
| 16 | Statistical damage detection method for frame structures using a confidence interval显示文摘A novel damage detection method is applied to a 3-story frame structure,to obtain statistical quantification control criterion of the existence,location and identification of damage.The mean,standard deviation,and exponentially weighted moving average(EWMA) are applied to detect damage information according to statistical process control(SPC) theory.It is concluded that the detection is insignificant with the mean and EWMA because the structural response is not independent and is not a normal distribution.On the other hand,the damage information is detected well with the standard deviation because the influence of the data distribution is not pronounced with this parameter.A suitable moderate confidence level is explored for more significant damage location and quantification detection,and the impact of noise is investigated to illustrate the robustness of the method. | Li Weiming,Zhu Hongping~(++),Luo Hanbin~(++) and Xia Yong~(++) School of Civil Engineering and Mechanics,Huazhong University of Science and Technology,Wuhan 430074,China ~+PhD Candidate ++ Professor | 2010 | Earthquake Engineering and Engineering Vibration2010，9，1： | 2 |
