However, there are few reports of the fundamental transport properties of greenhnouse gases, such as CF4, in polyers. In this regard, the permeability of dense films of five polymers to a series of ten gases and vapors including CF4, C2Fy, C3F8, and their hydrocarbon analogs, was ...
[translate] amany gases exhibit these "greenhouse" properties.Some of them occur in nature (water vapor,carbon dioxide,methane,and nitrous oxide),while others are exclusively human-made 许多气体陈列这些“温室”物产。而其他完全人造,有些发生本质上(水蒸气、二氧化碳、甲烷和氧化亚氮) [translate] ...
Mike:Sugar cane seems to be controversial. It doesn’t require as much fertilizer as corn does to grow, but when they burn the sugar cane fields, that releases loads of greenhouse gases. Karina:Yes, but some critics have suggested thatthe production of corn ethanol uses up more fossil fuel...

This limitation becomes apparent when handling scenarios with large changes in cloud properties, e.g., 1) presence of greenhouse gases->loss of clouds or 2) engineered intervention like cloud brightening->increased cloud reflectivity. Climate intervention techniques—like marine cloud brightening—that ...
Whereas one of the program accreditation requirements specifically addresses the need to incorporate design of components or processes of thermal systems into the curriculum, does this necessarily include all (or any) of the following: fossil fuel combustion, greenhouse gas production, alternative energy...
reactions including carbon monoxide oxidation, catalytic decomposition of greenhouse gases (CO2, N2O, CH4), catalytic combustion (oxidation) of soot, and the growth of the CNTs. Through this chapter, we hope to provide the readers with a distinct perspective of the present and future of this ...
Supplementary cementitious materials to mitigate greenhouse gas emissions from concrete: can there be too much of a good thing? J Clean Prod. 2018;178:587–98. Article Google Scholar P. No. Alternative supplementary cementitious materials in ultra-high performance concrete. 2022. Ndahirwa D, Zma...
These activities have a great influence on the environment and the developing of the polyurethane industry. The most apparent effects include the reduction of energy consumption during bio-based monomers and then polymers production, the decrease at the greenhouse gases emission and CO2 emission. More...
To address the growing energy demand of electricity in Gen-IV plants and mitigate the problem of emission of greenhouse gases, modified 9Cr–1Mo steel designated as ASTM A213 T91 for the seamless tube, ASTM A335 P91 for seamless pipe, and ASTM A387 Gr.91 for steel plates, has been devel...
