| 1 | Adsorption capacity of hydrophobic SiO_2 aerogel/activated carbon composite materials for TNT显示文摘The adsorption properties of TNT from wastewater by hydrophobic silica aerogel/activated carbon composite materials were investigated. The effects of adsorption time, pH value, adsorption temperature, and the amount of the composite materials on the adsorption rate were studied. The adsorption principle and mechanism of the composite materials were discussed along with the Freundlich equation. The results showed that the best adsorption rate of the hydrophobic silica aerogel/activated car-bon composite materials could reach 96.5% with adsorption conditions of adsorption temperature 25°C, pH value 7, the amount of SiO2aerogel dosage 3.33 g/L, and adsorption time of 120 min. The adsorption of hydrophobic SiO2aero-gel/activated carbon composite materials for TNT solution is mainly surface adsorption, and also has some chemical adsorp-tion when the aerogel hydrophobicity is modified. | ZHOU XiaoFang CUI Sheng LIU Yu LIU XueYong SHEN XiaoDong WU ZhanWu | 2013 | Science China(Technological Sciences)2013，56，7： | 5 |
| 2 | Structural and dielectric properties of SrFe_(x)Ti_(1-x)O_(3)(x=0.001,0.005 and 0.01)ceramics显示文摘Three different SrFe_(x)Ti_(1-x)O_(3)(x=0.001,x=0.005,x=0.01)ceramics were prepared by the conventional solid-state reaction.The crystalline structure,surface morphology and dielectric properties were studied by X-ray diffraction(XRD),scanning electron microscope(SEM)and Agilent 4294A impedance analyzer,respectively.It is shown that both the sintering temperature and doping concentration influence the lttice constant,grain size,dielectric constant and the dielectric loss.When the sintering temperature is higher than 1390℃,the lttice constant,grain size and dieletric constant all decrease with the increase of the doping concentration,except the dielectric loss tangent which shows the opposite trend.Leakage curent tests show that the leakage curent density falls down with the increase of Fe doping concentration in the given region. | Zhanwu Yu Peng Shi Wei Ren Xiaoqing Wu Xi Yao | 2013 | Journal of Advanced Dielectrics2013，3，1： | 0 |
| 3 | Late Quaternary Activity of the Central-North Segment of the Taihang Mountains Piedmont Fault Zone显示文摘The location and late Quaternary activity of the Central-North Segment of the Taihang Mountains Piedmont fault zone have been studied by shallow seismic survey and combined drill exploration.Our results show that the Baoding-Shijiazhuang fault and the Xushui fault were active in the late Pleistocene,but the south Xushui fault has been inactive since the late Pleistocene.The maximum magnitude of potential earthquake of the faults is 6.0. | Gao Zhanwu Wu Hao Li Gangtao Cheng Li | 2015 | Earthquake Research in China2015，29，1： | 0 |
| 4 | Pomegranate-like C_(60)@cobalt/nitrogen-codoped porous carbon for high-performance oxygen reduction reaction and lithium-sulfur battery显示文摘Porous carbon materials play essential roles in electrocatalysis and electrochemical energy storage.It is of significant importance to rationally design and tune their porous structure and active sites for achieving high electrochemical activity and stability.Herein,we develop a novel approach to tune the morphology of porous carbon materials(PCM)by embedding fullerene C_(60),achieving improved performance of oxygen reduction reaction(ORR)and lithium-sulfur(Li-S)battery.Owing to the strong interaction between C_(60)and imidazole moieties,pomegranate-like hybrid of Ow-embedded zeolitic imidazolate framework(ZIF-67)precursor is synthesized,which is further pyrolyzed to form C_(60)-embedded cobalt/nitrogen-codoped porous carbon materials(abbreviated as C_(60)@Co-N-PCM).Remarkably,the unique structure of C_(60)@Co-N-PCM offers excellent ORR electrocatalytic activity and stability in alkaline solutions,outperforming the commercial Pt/C(20 wt.%)catalyst.Besides,C_(60)@Co-N-PCM as a novel cathode delivers a high specific capacity of-900 mAh·g^(-1) at 0.2 C rate in Li-S batteries,which is superior to the pristine ZIF-67-derived PCM without embedding C_(60). | Jianhua Wu Shiyang Wang Zhanwu Lei Runnan Guan Muqing Chen Pingwu Du Yalin Lu Ruiguo Cao Shangfeng Yang | 2021 | Nano Research2021，14，8： | 0 |
| 5 | Crustal Structure of the Chuan-Dian Block Revealed by Deep Seismic Sounding and its Implications for the Outward Expansion of the East Tibetan Plateau显示文摘The Chuan-Dian Block(CDB)is located in the southeastern margin of the Tibetan Plateau,with a complex geological structure and active regional faults.The present tectonic condition with strong crustal deformation is closely related to the ongoing collision of the India and Eurasia plates since 65 Ma.The study of the crustal structure of this area is key to revealing the evolution and deep geodynamics of the lateral collision zone of the Tibetan Plateau.Deep seismic sounding is the most efficient method with which to unravel the velocity structure of the whole crust.Since the 1980s,19 deep seismic sounding profiles have been captured within the CDB area.In this study,we systematically integrate the research results of the 19 profiles in this area,then image the 3D crustal velocity,by sampling with a 5 km spacing and 2D/3D Kriging interpolation.The results show the following.(1)The Moho depth in the study area deepens from 30 km in the south to 66 km in the north,whereas there is no apparent variation from west to east.The Pn wave velocity is higher in stable tectonic units,such as 7.95 km/s in the Lanping-Simao block and 7.94 km/s in the western margin of the Yangtze block,than in active or mobile tectonic units,such as 7.81 km/s in the Baoshan block,7.72 km/s in the Tengchong block and 7.82 km/s in the Zhongdian block.(2)The crustal nature of the Tengchong block,the northern Lanping-Simao block and the Zhongdian block reflects a type of orogenic belt,having relatively strong tectonic activities,whereas the crustal nature of the central Lanping-Simao block and the western margin of the Yangtze block represents a type of platform.The different features of the upper-middle crust velocity,Moho depth and Pn wave velocity to both sides of the Red River fault zone and the Xianshuihe fault zone,reflect that they are clearly ultra-crustal.(3)Based on the distribution of the low velocity zones in the crust,the crustal material of the Tibetan Plateau is flowing in a NW–SE direction to the north of 26°N and to the west of 101°E,then diverting to flowing eastwards to the east of 101°E. | XIONG Xiaosong WANG Guan LI Qiusheng LU Zhanwu GAO Rui FENG Shaoying WU Guowei | 2022 | Acta Geologica Sinica(English Edition)2022，96，6： | 0 |
