| 1 | Synthesis of Isotopically-Labeled Graphite Films by Cold-Wall Chemical Vapor Deposition and Electronic Properties of Graphene Obtained from Such Films显示文摘We report the synthesis of isotopically-labeled graphite films on nickel substrates by using cold-wall chemical vapor deposition(CVD).During the synthesis,carbon from^(12)C-and^(13)C-methane was deposited on,and dissolved in,a nickel foil at high temperature,and a uniform graphite film was segregated from the nickel surface by cooling the sample to room temperature.Scanning and transmission electron microscopy,micro-Raman spectroscopy,and X-ray diffraction prove the presence of a graphite film.Monolayer graphene films obtained from such isotopically-labeled graphite films by mechanical methods have electron mobility values greater than 5000 cm^(2)·V^(-1)·s^(-1)at low temperatures.Furthermore,such films exhibit the half-integer quantum Hall effect over a wide temperature range from 2 K to 200 K,implying that the graphite grown by this cold-wall CVD approach has a quality as high as highly oriented pyrolytic graphite(HOPG).The results from transport measurements indicate that^(13)C-labeling does not significantly affect the electrical transport properties of graphene. | Weiwei Cai Richard D.Piner Yanwu Zhu Xuesong Li Zhenbing Tan Herman Carlo Floresca Changli Yang Li Lu M.J.Kim Rodney S.Ruoff | 2009 | Nano Research2009，2，11： | 7 |

| 7 | Variation of Dust in Northern China and Its Reproduction in BCC-ESM1 since 1980显示文摘In this paper,we explore the possible causes and mechanisms for the variation of dust in northern China from 1980to 2014 using the Modern-Era Retrospective analysis for Research and Applications version 2(MERRA-2)data,observational data,and BCC-ESM1(Beijing Climate Center Earth System Model version 1)simulation data.Two important dust centers are identified in China:one in the Taklamakan Desert in southern Xinjiang Region and the other in the Badain Jaran Desert in western Inner Mongolia Plateau.Both centers display distinct seasonal variations,with high dust concentration in spring and summer and low in autumn and winter.BCC-ESM1 is able to generally capture the main spatial and temporal characteristics of dust in northern China.Both the MERRA-2 reanalysis data and BCCESM1 simulation data show a decreasing trend in spring dust,which is evident during 1980–2000 and 2001–2014.The analysis based on daily mean dust loads and wind fields from MERRA-2 and BCC-ESM1 indicates that dusty weather in North China may be mainly caused by transport of the dust,especially that from the central and western Inner Mongolia Plateau during the prior 0–2 days,through the westerly winds from the upstream“dust core”region(38°–45°N,90°–105°E).This is one of the important paths for dust to move into North China.The weakened westerly wind in the lower troposphere in this“dust core”region may be responsible for the reduction of spring dust in North China. | Yumeng ZHOU Tongwen WU Jie ZHANG Yong ZHANG Yanwu ZHANG He ZHAO Weihua JIE Yang ZHOU Kalli FURTADO | 2023 | Journal of Meteorological Research2023，37，5： | 0 |
| 8 | Nondestructive testing and assessment of consolidation effects of earthen sites显示文摘Earthen sites are widely distributed throughout China,and most of them belong to archaeological sites with significant values,which not only directly witness the origin,formation and development of Chinese civilization,but also possess important values for conservation and exhibition.Many researches and practices on their conservation and consolidation have been carried out:however,the consolidation effect is mainly judged by visual observation and expert evaluation.Scientific assessment of conservation and consolidation effects is a challenging issue.Many instruments in other fields cannot be directly applied to the conservation of cultural relics due to their peculiarity.In order to assess the effects of field conservation experiments,this paper tries to understand the consolidation effects at Liangzhu site using nondestructive or micro-damage methods,including thermo-physical parameters testing,infrared thermal imaging,high-density microelectrode resistivity testing,portable microscope observation,and hydrophilic and hydrophobic testing,and thereby explores the practicable methods for evaluating the properties of consolidation materials for earthen sites treatment. | Xudong Wang Qinglin Guo Shanlong Yang Dexuan Zhang Yanwu Wang | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016，8，5： | 0 |
