Polypropylene/Multiwall carbon nanotubes/Montmorillonite (PP/MWNTs/MMT) hybrid nanocomposites were prepared by using twin-screw extruder incorporating the polypropylene grafted maleic anhydride (PP-g-mA) as compotibilizer is used for better dispersion of nanoclay in the polymer matrix. The effect of MWNTs and MMT on the polypropylene matrix was investigated in terms of mechanical properties of ...

Tissue engineering technology requires porous scaffolds, based on biomaterials, which have to mimic as closely possible the morphological and anisotropic mechanical properties of native tissue substitute. Anisotropic fibrous scaffolds fabricated by template-assisted electrospinning are investigated in this study. Fibers electrospun Polycaprolactone (PCL) were successfully arranged spatially int...

The possibility of using cellulose from the cell walls of kenaf, an annual herbaceous crop, for the production of bicomposites was investigated in this study. The composites were prepared using LDPE, as a matrix, the extracted cellulose, as filler and PEG as a plasticizer. The characterization of biocomposites was then performed with optimized thermo-mechanical properties and propensity to envi...

desert truffles, hypogeous pezizales (ascomycota), are difficult to identify due to evolutionary convergence of morphological characters among taxa that share a similar habitat and mode of spore dispersal. in this paper we document the presence of picoa lefebvrei (pat.) maire (=phaeangium lefebvrei) in iran and use phylogenetic analysis of the its and 28s rdna to show that this species belongs ...

New PVC/ABS and CoCl2 composites with various concentrations of cobalt chloride (?10 wt. %) were synthesized by solution casting techniques investigated spectro-chemical, morphological thermal mode characterization. The FT-IR, XRD SEM analyses proved the smooth distribution uniformity constituents composite materials. Thermal behavior showed that addition to blends enhanced stability improved m...

Thermo-deformable plastic films experience an optical birefringence phenomenon when they are subjected to mechanical strain, this phenomenon can be described by color fringes behavior observed in sequences of images acquired through photoelasticity assemblies. This paper proposes a temporary morphological analysis that color fringes experience when the plastic film is deformed. For the image an...
