Experimental and numerical analyses for the effect of the thickness of gap generator blank(GGB) on the formability of the outer blanks were investigated. The thickness of the GGB has the greatest impact on the thinning of the lowest blank. In addition, the friction at different regions and the additional interlayer contacts can also affect the thinning of different regions as well as increase the punch force. This work will enhance the understanding of simultaneous multi-layered blanks forming and will help the composite design engineers to tailor requirement-specific hybrid parts such as fiber metal laminates(FMLs) and functionally graded structures(FGSs) for hi-tech applications. 展开更多

The paper intends to analyze economic factors that influence electricity consumption in the OECD economies. A special interest in this context is given to spillover effects of trade on electricity consumption. For this purpose, a model is constructed that using a dynamic panel study approach. The model is estimated in a GMM framework in which a dynamic procedure is conducted along the balanced growth path for electricity consumption in each economy. In advance, the long run dynamic behavior of prices, GDP, and trade induced spillover variables is determined. In a further step, the short run dynamic mechanism is pursued by estimating the partial adjustment dynamic coefficient on the target level of electricity consumption. The analysis is conducted for industrial, as well as residential electricity consumption. Alternatively, the same procedure is estimated by the application of a fixed period model. The model provides a benchmark tool for electricity policy decisions and for electricity consumption projections. 展开更多

Improving charge carriers separation to achieve high photoconversion efficiency in heterogeneous photocatalysts is highly desirable.Herein,heterostructured ZnS@CdS double-layered porous nanotubes(PNTs),in which the spatially separated reduction and oxidation reaction sites lie on the outer and inner shell,respectively,are fabricated through a robust self-template conversion strategy.After selective photo-deposition of Ni and CoO_x as dual cocatalysts,Ni nanoparticles as electron collectors and reduction reaction sites are loaded on the outer shell,while CoO_x nanoparticles as hole collectors and oxidation reaction sites are loaded on the inner shells.As a result,a novel CoO_x/ZnS@CdS/Ni photocatalyst is obtained and shows high visible-light-driven photocatalytic hydrogen production activity owing to the synergistic effect of self-template-derived thin mesoporous heterojunctions and photo-depositionderived spatially separated dual cocatalysts,which can significantly provide driving force for the ordered transfer of photogenerated electrons and holes toward opposite direction and promote the surface catalytic reaction.Additionally,the facile strategy can be broadened to the preparation of CoO_x/ZnSe@CdSe/NiPNTs with enhanced photocatalytic activity. 展开更多
