hydrogenation‚ (2) pyrolysis‚ (3) thermal and/or catalytic cracking‚ (4) gasification and bioconversion [2‚ 3]. Literature reports several papers on pyrolysis of plastic wastes [4]. The decomposition of a polymer mixture over HZSM-5 modified with phosphoric acid zeolite catalysts (PZSM-5) has been comparatively studied [5]. Catalytic decomposition increased the amount of gaseous products‚ lowered the condensate‚ and changed their composition with respect to non-catalytic at the same pyrolysis temperature. The

Catalytic hydrogenation of graphene films† We developed a novel and facile method to hydrogenate grapheme by using a conditioning upstream of the graphene sample to generate atomic hydrogen Inspired by the elegant idea to create graphane‚1there have been some efforts to decorate the graphene lattice with hydrogen atoms to transform it from a highly conductive zero-overlap semimetal into a nonzero gap semiconductor and thus tune its electric properties to suit wider practical applications.234 However

Role of Air Transport in the Economy 1. In an increasingly globalised economy‚ air transport is a vital element of the country’s transport infrastructure. The impact of civil aviation as a sector on the general economic activity has been studied systematically and documented for some of the Western developed countries. By itself‚ the Civil Aviation Sector contributes significantly to the process of development by generating employment opportunities directly and indirectly besides facilitating enhancement
