  • Characterization of Photoelectric Properties and Composition Effect of TiO2/ZnO/Fe2O3 Composite by Combinatorial Methodology
    Journal of combinatorial chemistry, 2010
    Co-Authors: Yichuan Liao, Yuan Liu, Zhijun Zou, Dawen Zeng, Changsheng Xie
    Abstract:

    On the basis of combinatorial methodology and the idea of an equilateral ingredient triangle, the TiO2/ZnO/Fe2O3 composite system including 66 ingredient points was designed. The photocurrents under different light sources and bias voltages were measured, and the photocurrent amplitude at 300 s was chosen as a parameter to evaluate the photoelectric response of the composite. To appraise the Composition Effect of the composite compared with pure materials, the quantitative formula of the Composition Effect has been provided for the first time in this paper. We found that not all the ingredient points demonstrated the enhanced Composition Effect in the as-designed ingredient triangle material library. The reasons of different Composition Effect for different ingredient points have been discussed in detail. X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) were used to investigate the phase structure and the grain morphology of the composite.

  • determining the trade environment Composition Effect the role of capital labor and environmental regulations
    Journal of Environmental Economics and Management, 2003
    Co-Authors: Matthew A. Cole, Robert J. Elliott
    Abstract:

    This paper argues that pollution-intensive sectors may be subject to opposing forces of comparative advantage since these sectors are also typically capital intensive, yet regions with low environmental regulations tend to be those that are the least capital abundant. We examine therefore, whether Compositional changes in pollution arising from trade liberalization originate due to differences in capital–labor endowments and/or differences in environmental regulations. The contribution of the paper is threefold; first, we provide a comprehensive empirical analysis of the determinants of four common pollutants, paying particular attention to the nature of the trade-induced Composition Effect; second, we investigate whether the result of Antweiler et al. (Amer. Econom. Rev. 91 (2001) 877), who find evidence that both environmental regulations and capital–labor endowments determine sulfur dioxide concentrations, also holds for sulfur dioxide emissions; third, we examine whether this result holds for altogether different pollutants. Our results, while providing partial support for Antweiler et al., also raise a number of points for discussion.

  • carbon emission curbing Effects and influencing mechanisms of china s emission trading scheme the mediating roles of technique Effect Composition Effect and allocation Effect
    Journal of Cleaner Production, 2020
    Co-Authors: Shuo Chen, Anna Shi
    Abstract:

    Abstract Based on panel data from 2007 to 2016, this paper investigates the carbon abatement Effect of China’s pilot Emission Trading Scheme (ETS) and the influencing paths of the policy at both national and regional level by using Difference in Differences model and parallel multiple mediator model. The results reveal that the policy has reduced the total carbon emission reduction by 13.39%, with an upward abatement trend annually. Secondly, a systematic framework containing technique Effect, Composition Effect and allocation Effect is proposed to further investigate the influencing mechanisms of the achieved emission curbing Effect. It reflects that the policy has not yet promoted the low-carbon innovation completely, only innovation of high-quality played an Effective mediating role. Meantime, two other influencing channels of industrial upgrading and optimized resource allocation are verified. Thirdly, policy’s heterogeneous impacts are detected by classifying China into three representative regions according to economic and geographical differences, where western China experiences the strongest emission abatement by 21.57%, whereas central China and eastern China is 9.83% and 6.65% respectively. Fourthly, assessments of the regional influencing mechanisms show that the mediating role of high-quality low-carbon technology innovation is only significant in the western region, while the other two regions tend to have rebound Effect. Besides, the promotion of industrial upgrading is positively related to the development levels of regions, with the improvement of 18.01% in the eastern region, followed by 17.34% and 12.46% in the central and western region. Finally, the optimization of the resource allocation has not been promoted regardless of the regions. In general, although the current policy has a significant carbon reduction Effect, there is still much space for potential abatement to be developed.
