Energy use, CO2 emission and foreign direct investment： Is there any inconsistence between causal relations？

引用

Frontiers in Energy 2014年第3期8卷 269-278页

作者： Ertugrul yildirim Department of Economics Bulent Ecevit University Zonguldak 67100Turkey

In this study, the causal relations between inward foreign direct investment （FDI）-energy use per capita and inward FDI-CO2 emission per capita were analyzed and the inconsistency between the causal relations was investigated via bootstrap-corrected panel causality test and cross-correlation analysis. In this direction, data from 76 countries including the period of 1980-2009 was processed. No supportive evidence was found for changing causal relations to country group which was classified into income level. The findings indicated that while the pollution haven hypothesis was supported for Mozambique, United Arab Emirates and Oman, the pollution halo hypothesis was supported in the case of India, Iceland, Panama and Zambia. For other countries, energy use and CO2 emission were neutral to inward FDI flows in aggregated level. Furthermore, this study urged that increased （decreased） energy use due to the inward FD1 flows did not necessarily mean an increase （decrease） in pollution level, and vice versa. For policy purpose, FDI attractive policy should be regulated by taking into account this possibility.

Mechanical and Antibacterial Properties of Injection Molded Polypropylene/TiO_2 Nano-Composites:Effects of Surface Modification

引用

Journal of Materials Science & Technology 2012年第8期28卷 686-692页

作者： Mirigul Altan Huseyin yildirim Department of Mechanical Engineering Yildiz Technical UniversityYildizIstanbul34349Turkey Department of Chemistry Yildiz Technical UniversityDavutpasaIstanbul34210Turkey

Polypropylene （PP）/titanium dioxide （TiO2） nano-composites were prepared by melt compounding with a twin screw extruder. Nanoparticles were modified prior to melt mixing with maleic anhydride grafted styreneethylene-butylene-styrene （SEBS-g-MA） and silane. The composites were injection molded and mechanical tests were applied to obtain tensile strength, elastic modulus and impact strength. Antibacterial efficiency test was applied on the injection molded composite plaques by viable cell counting technique. The results showed that the composites including SEBS-g-MA and silane coated TiO2 gave better mechanical properties than the composites without SEBS-g-MA. Antibacterial efficiency of the composites varied according to the dispersion and the concentration of the particles and it was observed that composites at low content of TiO2 showed higher antibacterial property due to the better photocatalytic activity of the particles during UV exposure.
