The present work investigates the use of magnesium hydroxide, produced by magnesia hydration, as a fire retardant in polymers. The hydration was carried out in an autoclave, at temperature of 130°C for 1 hour, and the product was further submitted to cominution in a jet mill. The solids were characterized with regard to their chemical composition, particle size distribution, surface area and mo...

The development of lightweight automotive parts is an important issue for improving the efficiency of vehicles. Polymer composites have been widely applied to reduce weight and improve mechanical properties by mixing polymers with carbon fibers, glass fibers, and carbon nanotubes. Polypropylene (PP) has been added to carbon fiber-reinforced nylon-6 (CF/PA6) composite to achieve further weight r...

Purpose: To compare the outcome of corporeal plication using absorbable versus nonabsorbable sutures for the treatment of congenital penile curvature. Materials and Methods: Thirty-eight men older than 15 years old with congenital penile curvature were enrolled in the study. Patients were randomly divided into two equal groups based on the suture material (Nylon versus Vicryl) used in corporeal...

electrospinning is a method of nanofiber filter media production. by this method, it is possibleto produce media with nanofiber in the range of nanometer to micrometer. nanofibrous media provide a large specific surface area in a finite volume thus they are suitable for filtration applications. in this study, nanofiber non-woven membranes production of nylon-6 by electrospinning method is inves...
