Poly(Vinyl Alcohol) (PVA) films were prepared with AlCl3·6H2O/glycerin and AlCl3·6H2O/poly glycerin as two kinds of complex plasticizer. The micromorphology of pure PVA film and PVA films plasticized with complex plasticizer was observed by Scanning Electron Microscope (SEM). The interaction between complex plas...

the effect of enzymatic treatment time of microbial transglutaminase (mtgase) on the characteristics of whey protein isolate (wpi) films was investigated. results shown that the properties of mtgase-treated films were affected by increasing the enzymatic treatment time. enzymatic treatment at lower incubation time, i.e. for 1 h, significantly resulted in higher values of tensile strength (ts) a...

the main objective of this study was to produce ldpe active films containing metallic nanoparticles (ag, zno and cuo) and to investigate their physical, mechanical and anti-microbial characteristics. three types of metallic nanoparticles at concentrations of 1% (w/w) were added to low density polyethylene (ldpe) and the films were prepared using melt extrusion technique. sem results indicated r...

the purpose of this study was to explore whether film-based dynamic assessment (da) could affect english writing of iranian deaf children. ten students studying in a school for the deaf took part in the study. the participants’ writing ability was measured prior to the treatment and the errors which were identified. a series of meditating activities were designed and implemented during a three-...

objective: to determine the effects of application of anti-adhesive films (orthowrap™) in traumatic decompressive craniectomy on prevention of adhesion formation and facilitation of subsequent cranioplasty. methods: this was a retrospective cohort study being performed in shahid rajaei hospital (shiraz level i trauma center) during a 12-month period (from march 2012 to april 2013) including 93 ...

the widely shocking attacks on the world trade center and the pentagon on september 11 was interpreted differently by various institutions worldwide, ranging from america's legitimate motive to begin a 'war on terror' to defend her 'very freedom', to a pretext for bush administration to pursue g. h. w. bush's temptation for 'a new world order'. various institutions, therefore, made use of their...

the influences of anionic sodium dodecylsulfate (sds) and cationic hexadecyltrimethylammonium bromide (htab) surfactants on the incorporation and distribution of barium hexaferrite nanoparticles in the electrodeposited cofe-bafe12o19 composite thin films were studied. sulphate bathes with natural ph containing 0 to 2 g/l surfactants were used for electroplating at room temperature. field emissi...

polyurethane/zeolite 13x nanocomposite films were fabricated using solution casting method. the synthesized nanocomposite films were structurally characterized using sem, tga and tensile analysis. sem images showed appropriate distribution of nanocrystalline zeolite particles within polyurethane matrix. better thermal stability of nanocomposite films in comparison to neat polyurethane was shown...
