چکیده
Up to now, so many studies have not been trying to fabricate new filter media by using CNTs.Vander Wal and Hall and Johnson et al. [1] synthesized directly CNTs upon a metal mesh screen. By growing nanotubes onto a micro pores, Pyrex filters efficiency may be improved. However, the filter composed of entirely nanotubes is not available as a gas or air filters because its pressure drop is considerably high, so that the technical approach that nanotubes are coated onto pyrex filters has been proposed and applied to fabricate nano-filters. Graham et al. have shown that the coating of nanofibers, produced by electrospinning method, on the surface of conventional micron-fibrous filters can significantly improve the filter performance. Carbon nanotubes (CNTs) have considerable aspect ratio and specific surface area, so that they are suggested as a new material, which may be applied for hydrogen storage, gas absorption, filtration and separation [2]. In this study, we have synthesized CNTs, by a CVD method; in porous pyrex membraneکلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
