| 1 | Redevelopment of urban brownfield sites in China:Motivation,history,policies and improved management显示文摘Rapid urbanisation in China has resulted in an increased demand for land in towns and cities.To upgrade and modernise,China has also moved many major industries from urban centres to less populated areas.With the high economic value of urban land,the transformation and utilisation of brownfield areas have become important economically and socially.The Chinese government has recognised the need for strong frameworks to safeguard soil and groundwater quality,with brownfield sites a key category for management.Strong scientific,regulatory and decision-making frameworks are needed and being adopted to ensure practical,careful and wise use of central and localised government resources,to manage the reuse and regeneration of these brownfield sites.This paper reviews the context,policies and management procedures of developing brownfield sites in countries with a history of brownfield management and discusses China’s current situation and priorities for brownfield governance and redevelopment.These include(1)clarification of brownfield site soil contamination risk control standards and risk assessment procedures,(2)the responsibilities of different national and local agencies,(3)the establishment of a national expert committee to advise on best practices,policy and process,(4)the use of registered brownfield databases at national,provincial,municipal and county levels,and(5)the set up of soil pollution prevention fund at the provincial level. | Yiming Sun Hong Li Shuo Lei Kirk TSemple Frederic Coulon Qing Hu Jingyang Gao Guanlin Guo Qingbao Gu Kevin C.Jones | 2022 | Eco-Environment & Health2022，1，2： | 2 |

| 11 | Fabrication and origin of asymmetric polyvinylidene fluoride-carbon nanotube/ cyanate ester materials with high dielectric constant and low dielectric loss through building double-layered structure显示文摘High dielectric loss has been the biggest sticky problem for high-k conductor/polymer composites.Herein,a new asymmetric material consisting of one layer ofβ-phase poly(vinylidene fluoride)(PVDF)and another layer of carboxylated carbon nanotube(eCNT)/cyanate ester(CE)composite was fabricated,coded as PVDFx–eCNTq/CE,where x is the thickness of PVDF layer ranging from 3 to 70μm,q is the loading of eCNTs(f),taking values of 1.2 and 1.7 wt%.The influences of f and x values on dielectric properties and breakdown strengths of PVDF–eCNT/CE materials were systematically studied.When f is smaller than the percolation threshold(fc)of eCNT/CE(fc=1.6 wt%),the corresponding PVDF–eCNT1.2/CE materials have similar conductive and dielectric properties as eCNT1.2/CE composite.When f>fc,all PVDF–eCNT1.7/CE materials have much lower dielectric loss than eCNT1.7/CE,while with suitable thickness of PVDF layer(<70μm),PVDF–eCNT/CE materials have significantly improved dielectric constants and breakdown strengths.For the PVDF–eCNT1.7/CE material of which the thickness of PVDF layer is 5μm,its dielectric constant at 1 Hz is 1699,about ten times of that of eCNT1.7/CE,while the dielectric loss is only 2.31×10−2 times of that of the latter.The origin behind was intensively studied in terms of space charge distribution. | Longhui Zheng Li Yuan Qingbao Guan Aijuan Gu Guozheng Liang | 2017 | High Voltage2017，2，1： | 0 |
| 12 | Effect of hydration film on scanning images of atomic force microscope显示文摘A standard calibration grating was used for image scanning to investigate the effect of hydration films on imaging resolution by Atomic Force Microscope (AFM). The results showed that the hydration films greatly affect the imaging resolution for the tapping mode, but no evident effect on the contact mode. The possible reasons for the effect of hydration films on scanning images of AFM are also brought forward here. | Changsheng Peng Qingbao Gu Hong Meng Shaoxian Song | 2006 | Journal of University of Science and Technology Beijing2006，13，1： | 0 |
