higher solid contents (20 % and 40 %) nanocomposites of poly (styrene-co-butyl acrylate) including higher content of cloisite 30b (7 wt% and 10 wt %) were prepared via miniemulsion polymerization. stability of the final latexes proved outstanding combination of polymerization procedure and surfactants. morphological studies revealed by tem, sax and xrd showed three structures of core-shell, arm...

margarine contains a higher level of unsaturated and trans-fatty acids (tfa) than butter. the aim of this study was to investigate the physicochemical properties of these products in iranian market during storage. physicochemical analyses included fatty acid composition, peroxide and anisidine values, slip melting point (smp), color, chlorophyll content, solid fat content (sfc) and texture anal...

chemical wastewater treatment is one of the attracting and common methods for wastewater treatment among the currently employed chemical unit processes. the use of coagulant-flocculant compound is one of the efficient methods for separating of paint and recovery of water. in this research, it was introduced and the effect of ph on removal of solid content from solution was studied experimentall...

high solid content poly (styrene-co-butyl acrylate) latex ( with 20% and 40% solid content) including high amounts of cloisite 30b (7 wt% and 10 wt%) were kinetically investigated. gravimetric method via measuring the rate of polymerization, number of particles and average number of radicals per particle was used. results showed that by increasing the solid content; the average diameter of poly...

the physical properties of the municipal solid waste (msw) in kahrizak landfill (tehran, iran) and its changes due to aging were investigated in this research. a study of the components of the fresh msw in this landfill showed that more than 60% of it was made from the wastes of foods, fruits, vegetables and organic materials. next to that, paper/cardboard and plastics, with contributions of 14...

organic fraction of solid waste, which upon degradation produces foul smell and generates pathogens, if not properly managed. composting is not a method of waste disposal but it is a method of waste recycling and used for agricultural purposes. an integrated approach of composting methodology was tested for municipal solid waste management. solid waste first was composted and after 22 days, was...
