1Preparation of hierarchical mesoporous Zn/HZSM-5 catalyst and its application in MTG reaction显示文摘The hierarchical mesoporous Zn/ZSM-5 zeolite catalyst was prepared by NaOH treatment and Zn impregnation, and its application in the conversion of methanol to gasoline (MTG) was studied. N2 adsorption-desorption results showed that the mesopores with sizes of 2–20 nm in HZ5/0.3AT was formed by 0.3 M NaOH alkali treatment. The zeolite samples after modification were also characterized by XRF, AAS, XRD, SEM and NH3-TPD methods. Zn impregnated catalyst Zn/HZ5/0.3AT exhibited dramatic improvements in catalytic lifetime and liquid hydrocarbons yield. The selectivity of aromatic hydrocarbons was also improved after Zn impregnation. It is suggested that the mesopores of Zn/HZ5/0.3AT enhanced the synergetic effect of Zn species and acid sites and the capability to coke tolerance, which were confirmed by the results of catalytic test and TGA analysis, respectively.Youming Ni Aiming Sun XiaolingWu Guoliang Hai Jianglin Hu Tao Li Guangxing Li 2011Journal of Natural Gas Chemistry2011,20,3:31
2Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21
3Branched aliphatic alkanes of shell bar section in Qarhan Lake,Qaidam Basin and their paleoclimate significance显示文摘Biomarkers of paleolake deposits from Qarhan Salt Lake in Qaidam Basin,northwest China were sys-tematically analyzed and the A―C series compounds of branched aliphatic alkanes with quaternary substituted carbon atom(BAQCs) were identified. The homologous distinguished three series,A―C,were identified as 5,5-diethylalkanes,6,6-diethylalkanes and 5-butyl,5-ethylalkanes series,and their relative abundance was A > B > C. Series A and C were characterized by odd carbon numbers,whereas series B was characterized by even carbon numbers. The high values of series A corresponded with the high values of series B and C. Therefore,it can be concluded that series A,B and C possess a similar biological origin. The abundance of series A was relatively low in the lower part of the section compared with that in the upper part,implying that these series originated from bacteria and/or algae more prevalent in fresh-mesohaline water,and such kinds of bacteria and/or algae are most likely to be thermophilous species. The A25/nC25 ratio differences in the section show that such branched aliphatic alkanes can be treated as one kind of environmental change proxy for paleolake evolution and may provide important information for the climate reconstruction of the Late Pleistocene.ZHANG HuCai CHANG FengQin LI Bin LEI GuoLiang CHEN Yue ZHANG WenXiang NIU Jie FAN HongFang YANG MingSheng 2007Chinese Science Bulletin2007,52,9:13
4A bi-directional gap model for simulating the directional thermal radiance of row crops显示文摘Row crops are a kind of typical vegetation canopy between discrete canopy and continuous canopy. Kimes et al. studied the directional thermal radiation of row crops using the geometrical optical model, which simplified row structure as 'box' and neglected the gap among foliage and did not consider the emissivity effects. In this work we take account of the gaps along illumination and viewing directions and propose a bi-direction gap model on the basis of the idea of gap probability of discrete vegetation canopy introduced by 'Li-Strahler' and inter-correlation of continuous vegetation developed by Kuusk. It can be used to explain 'hot spot' effects in thermal infrared region. The gap model has been validated by field experiment on winter wheat planted in shape of rows and results show that the gap model is better than Kimes' model in describing the directionality of thermal infrared emission for row crops.CHEN Liangfu (陈良富) LIU Qinhuo (柳钦火) FAN Wenjie (范闻捷) LI Xiaowen (李小文) XIAO Qing (肖青) YAN Guangjian (闫广建) TIAN Guoliang (田国良) 2002Science China Earth Sciences2002,45,12:12
5Synthesis of a novel triple-site diphosphinoamine (PNP) ligand and its applications in ethylene tetramerization显示文摘A novel triple-site diphosphinoamine (PNP) ligand was synthesized and characterized. In combination with Cr(III) and methylaluminoxane (MAO), it generated active catalytic systems for ethylene tetramerization toward 1-octene with high catalytic activity and long lifetime. The effects of reaction temperature, molar ratio of Al/Cr and molar ratio of ligand/Cr on catalytic activity and selectivity to 1-octene were studied with reaction kinetics of the catalytic system for ethylene tetramerization described. At the Al/Cr molar ratio of 100, the catalytic activity is up to 2.29×106 g·mol-1 (Cr)·h-1 and the selectivity to 1-octene is 49.65 wt%.MAO GuoLiang NING YingNan HU WenBo LI ShanMing SONG XianFeng NIU Bo JIANG Tao 2008Chinese Science Bulletin2008,53,22:11
6Palladium Nanoparticle-Graphene Hybrids as Active Catalysts for the Suzuki Reaction显示文摘Graphene has been successfully modified with palladium nanoparticles in a facile manner by reducing palladium acetate [Pd(OAc)2] in the present of sodium dodecyl sulfate (SDS), which is used as both surfactant and the reducing agent. The palladium nanoparticle-graphene hybrids (Pd-graphene hybrids) are characterized by high- resolution transmission electron microscopy, atomic force microscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and energy dispersive X-ray spectroscopy. We demonstrate that the Pd-graphene hybrids can act as an efficient catalyst for the Suzuki reaction under aqueous and aerobic conditions, with the reaction reaching completion in as little as 5 min. The influence of the preparation conditions on the catalytic activities of the hybrids is also investigated.Yang Li Xiaobin Fan Junjie Qi Junyi Ji Shulan Wang Guoliang Zhang Fengbao Zhang 2010Nano Research2010,3,6:10
7Local and long-range transport influences on PM_(2.5) at a cities-cluster in northern China,during summer 2008显示文摘Hourly PM2.5 concentrations were observed simultaneously at a cities-cluster comprising 10 cities/towns in Hebei province in China from July 1 to 31,2008. Among the 10 cities/towns, Baoding showed the highest average concentration level(161.57(jig/m3) and Yanjiao exhibited the lowest(99.35(jig/m3). These observed data were also studied using the joint potential source contribution function with 24-h and72-h backward trajectories, to identify more clearly the local and countrywide-scale long-range transport sources. For the local sources, three important influential areas were found, whereas five important influential areas were defined for long-range transport sources. Spatial characteristics of PM2.5 were determined by multivariate statistical analyses. Soil dust, coal combustion, and vehicle emissions might be the potential contributors in these areas. The results of a hierarchical cluster analysis for back trajectory endpoints and PM2.5 concentrations datasets show that the spatial characteristics of PM2.5 in the cities-cluster were influenced not only by local sources, but also by long-range transport sources. Different cities in the cities-cluster obtained different weighted contributions from local or long-range transport sources. Cangzhou, Shijiazhuang, and Baoding are near the source areas in the south of Hebei province,whereas Zhuozhou, Yangfang, Yanjiao, Xianghe, and Langfang are close to the sources areas near Beijing and Tianjin.Lijie Gao Yingze Tian Caiyan Zhang Guoliang Shi Huize Hao Fang Zeng Chunli Shi Meigen Zhang Yinchang Feng Xiang Li 2014Particuology2014,12,2:9

10Tensor force effect on proton shell structure in neutron-rich Ca isotopes显示文摘In the framework of the Skyrme-Hartree-Fock approach with 36 sets of the TI J parameterizations,the tensor force effect on the evolution of the single-proton states in the calcium isotopes is systematically investigated.It is shown that the single-proton states with higher angular momenta are influenced significantly by the tensor force and the trend in the evolution of somesingle-particle energy differences with the mass number of the isotopes depends sensitively on a parameter βT associated with the intensity of the tensor force.To understand this phenomenon,we analyze the spin-orbit potentials and the radial wave functions of relevant single-proton orbits in detail.In addition,it is found that some TI J interactions could cause the 2s1/21d3/2 energy level inversion in 48Ca.LI ZhenYu WANG YanZhao YU GuoLiang GU JianZhong 2013Science China(Physics,Mechanics & Astronomy)2013,56,9:7
11Reduning injection for fever, rash, and ulcers in children with mild hand, foot, and mouth disease: a randomized controlled clinical study显示文摘OBJECTIVE: To assess the efficacy and safety of Reduning injection for fever, rash, and ulcers in children with mild hand, foot, and mouth disease(HFMD). METHODS: A stratified-block randomized, double-blind, parallel-controlled, and multicenter clinical trial was conducted with 360 patients in five hospitals across China: Quanzhou Children's Hospital, Shijiazhuang No. 5 Hospital, Shanghai Public Health Centre, Hunan Provincial Children's Hospital, and Kaifeng Children's Hospital. Patients were randomized into three groups with 120 in each. Group A was treated with Western Medicine, group B with Reduning injection, a Chinese herbal medicine, and group C with both Reduning injection and Western Medicine. Results were compared for treatment efficacy and safety on HFMD. The clinical outcomes were observed as follows: fever and onset time of antifebrile effect(time to bring the body temperature down ≥0.5℃ after medication); cumulative time for fever recovery(body temperature recovering to normal and lasting more than 24 h without medication); cumulative time for rash disappearance(without new rashes or ulcers appearing and the original ones fading away); and cumulative time for mouth ulcer disappearance. RESULTS: For the onset time of the antifebrile effect, there was no statistical difference between groups A and B(P>0.05) and groups B and C(P> 0.05). However, there was a statistical difference between groups A and C(P<0.05), and the effect in group C was the best. For the cumulative time for rash disappearance, there was no statistical difference between groups A and B(P>0.05). There were statistical differences between groups A and C, and groups B and C(P<0.05), and the effect in group C was the best. For the cumulative time for mouth ulcers disappearance, there were no statistical differences among the three groups(P>0.05). CONCLUSION: Reduning injection with Western Medicine for symptomatic treatment is most effective for mild HFMD. No adverse reactions were observed.Guoliang Zhang Jie Zhao Liyun He Shiyan Yan Ziqiang Zhuo Haojie Zheng Yongping Mu Shuangjie Li Xi Zhang Jihan Huang Xiuhui Li Jianping Liu Hehe Wan Chaoyu Wei Wei Xiao 2013Journal of Traditional Chinese Medicine2013,33,6:7
12Seismic response analysis of continuous rigid frame bridge considering canyon topography effects under incident SV waves显示文摘To evaluate the importance of the canyon topography effects on large structures, based on a rigid frame bridge across a 137-m-deep and 600-m-wide canyon, the seismic response of the canyon site is analyzed using a two-dimensional finite element model under different seismic SV waves with the assumptions of vertical incidence and oblique incidence to obtain the ground motions, which are used as the excitation input on the pier foundations of the bridge with improved large mass method. The results indicate that canyon topography has significant influences on the ground motions in terms of incident angle. The peak ground acceleration values vary greatly from the bottom of the canyon to the upper corners. Under vertical incident SV waves, at the upper corners of canyon the peak ground accelerations greatly increase; whereas the peak ground accelerations diminish at the bottom corners of canyon. Under oblique incident SV waves, the shaking of the canyon slope perpendicular to the incidence direction is much more severe than that of the opposite side of canyon. And the ground surface has been characterized by larger deformations in the case of oblique incident waves. It is also concluded that the low piers and frame of the continuous rigid frame bridge are more sensitive to the multi-support seismic excitations than the flexible high piers. The canyon topography as well as the oblique incidence of the waves brings the continuous rigid frame bridge severe responses, which should be taken into account in bridge design.Guoliang Zhou Xiaojun Li Xingjun Qi 2010Earthquake Science2010,23,1:7

17Coarsening behavior of γ' particles in a nickel-base superalloy显示文摘The coarsening behavior of γ' particles in a nickel-base superalloy FGH95 was investigated by means of experimental observations and growth kinetics calculations. The results show that when aging at 1000,1080 and 1140°C for different times,the relation of average particle size to time obeys the cube law ( a /2)3= kt,where k is 15.49 × 103,77.5 × 103 and 230.04 × 103 nm3/min,respectively. The particle size distributions are better fit to the LSW theoretical distributions when aging at 1000°C within 1440 min. The activation energy for γ' particles coarsening is determined to be 288.20±1.79 kJ/mol,which correlates well to the diffusion activation energies of Al,Ti,and Nb in the nickel matrix. This indicates that the coarsening of γ' particles is controlled by the diffusion of Al,Ti,and Nb in the nickel matrix. The coarsening kinetics of γ' particles in FGH95 is predicted as rt 3 = 1.04 × 10 16t exp[-(288200 ± 1790 )/RT].Li, Hongyu Zuo, Lingli Song, Xiping Wang, Yanli Chen, Guoliang 2009Rare Metals2009,28,2:5

20Mercury flows in large-scale gold production and implications for Hg pollution control显示文摘Large-scale gold production(LSGP) is one of the five convention-related atmospheric mercury(Hg) emission sources in the Minamata Convention on Mercury. However, field experiments on Hg flows of the whole process of LSGP are limited. To identify the atmospheric Hg emission points and understand Hg emission characteristics of LSGP, Hg flows in two gold smelters were studied. Overall atmospheric Hg emissions accounted for 10%–17% of total Hg outputs and the Hg emission factors for all processes were 7.6–9.6 kg/ton. There were three dominant atmospheric Hg emission points in the studied gold smelters, including the exhaust gas of the roasting process, exhaust gas from the environmental fog collection stack and exhaust gas from the converter of the refining process. Atmospheric Hg emissions from the roasting process only accounted for 16%–29% of total emissions and the rest were emitted from the refining process. The overall Hg speciation profile(gaseous elemental Hg/gaseous oxidized Hg/particulate-bound Hg) for LSGP was 34.1/57.1/8.8. The dominant Hg output byproducts included waste acid, sulfuric acid and cyanide leaching residue. Total Hg outputs from these three byproducts were 80% in smelter A and 84% in smelter B. Our study indicated that previous atmospheric Hg emissions from large-scale gold production might have been overestimated.Hg emission control in LSGP is not especially urgent in China compared to other significant emission sources(e.g., cement plants). Instead, LSGP is a potential Hg release source due to the high Hg output proportions to acid and sludge.Qingru Wu Shuxiao Wang Mei Yang Haitao Su Guoliang Li Yi Tang Jiming Hao 2018Journal of Environmental Sciences2018,30,6:5
