Based on the actual situation and the survey results in rural areas, with the domestic and foreign advanced green building standard as a reference, we initially determine the evaluation indicator system for rural green building. We use the AHP-Delphi method to calculate the weight, and get a...

Hydrogen production from NaBH4 hydrolysis is very important for environment-friendly fuel cells. Here Y-zeolite/CoCl2 doped PVDF (Polyvinylidene fluoride) composite nanofibers were prepared by co-electrospinning method and successfully applied into hydrogen production from NaBH4 hydrolysis. The...

Composite nanofiber sheets containing multiwalled carbon nanotubes and cobalt chloride dispersed in PAN (polyacrylonitrile) were produced by an electrospinning technique. The synthesized PAN/CoCl2/CNTs composite nanofiber was used as the catalyst for hydrogen production from the hydrolysis of...

Hydrogen was generated from ammonia borane complex by hydrolysis using cobalt nanocluster catalyst supported on polydopamine functionalized MWCNTs (multi-walled carbon nanotubes). The impregnation-chemical reduction method was used for the preparation of the supported catalyst. The nanocluster...

Reports show that it is necessary to control greenhouse gas emissions from the supply chain perspective. Numerous authors have already started quantifying the impacts of emission trading on supply chain performance in terms of cost and emissions. However, rare effort is made to conceptualize...

The micro-laminated (ZrO2–Y2O3)/(Al2O3–Y2O3) composite coatings were prepared on the surface of Fe–25Cr alloy by an electrochemical process and a sintering process alternately. FE-SEM analyses show that the cross section of the micro-laminated coatings has alternate six-layer films of...

A one-unit repairable system, supported by r repair facilities and s spare units, fails when all units are down and are undergoing or awaiting repair. Under the perfect repair policy and instantaneous commencement of repair and installation to operation, the limiting average availability of the...
