this is a comprehensive review of the recent progresses made in the field of zeolite membranes. it describes zeolitic materials and methods of membrane fabrication, followed by a summary of applications for gas separation, pervaporation and separation of liquid mixtures. special attention is called to polymer mixed matrix membranes (mmms) and membranes based on metal organic frame works (mofs)....

Polyaniline-cobalt nanocomposites were synthesized bysalt of cobalt with ammonium persulphate as an oxidizing agent and aniline.This paper reports on hydrothermal technique using for synthesis and size control of cobalt nanoparticles in the composite bridge is aniline. Electrical conductivity of polyaniline alone in acidic environments, without and with cobalt nanoparticles measured.Increasing ...

in this investigation we synthesized nax-nanozeolite by hydrothermal crystallization conditions.these nanoparticles were prepared at different conditions in a temperature controlled shaker. thesynthesized zeolites were characterized by instrumental analysis methods, such as x-raydiffraction (xrd), x-ray fluorescence (xrf), scanning electron microscopy (sem) andtransmission electron microscopy (...
