{ "item_title" : "A Study on the Effect of Addition of Tin Oxide Nano fiber", "item_author" : [" Farzan Fahimi "], "item_description" : "In the present study the effect of adding tin dioxide nano-fibers on sound propagation in concrete be examined. One of the ways that concrete can be used as insulating and sound-absorbing concrete reinforcement is by nano-material. In general, a public division, production of nano-materials into three categories: nano-particles, nano-fibers, nano-layers are divided. production of nano fibers that some of them, including stretching method, separation of multi-component fibers, molding method, tail, phase separation, self-assembly of macro-molecules, etc. are electro spun. The results of studies carried out by researchers active in the field of nano-fibers, electro-spinning process excellence compared to other methods is obtained. Electro-spinning process in terms of production speed, diversity, continuity, simplicity, cost and commercialization of the other methods is preferred.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/6/20/843/323/6208433231_b.jpg", "price_data" : { "retail_price" : "87.00", "online_price" : "87.00", "our_price" : "87.00", "club_price" : "87.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
