Nanocomposite composed of organoclay(Cloisite 20A-C20A) and Poly lactic acid (PLA) was prepared by solvent casting method. Physical, mechanical, thermal, barrier and microstructure properties of the composite were studied. X-Ray diffraction (XRD) patterns and scannin...
v2o5/sio2 nanoparticles was prepared via an one-pot sol gel method from vanadyl- acetylacetonate and tetraethylorthosilicate in refluxing meoh, followed by calcination at 700 °c for 2 hours. the resultant nanoparticles was characterized by means of scanning electron microscopy (sem), transmission electron microscopy (tem), x-ray diffraction (xrd), tga and ftir techniques. rapid and efficient ar...
nano-encapsulated iron oxide in zirconium oxide-coated mica pigments are thermally stable,innocuous to human health, non-combustible, and they do not conduct electricity. they could beapplied in several industries such as thermoplastics, cosmetics, food packaging, children toys, paints,automobiles coating, security purposes, and banknotes. nowadays, they are highly desirable inceramic decoratio...
Two nano-sized mixed-ligand Cd (II) coordination polymers; [Cd (4,4' -bpy) (C4H4O4)].1/4 H2O (1) and[Cd(bpy)1.5 (NO3)2].3H2O (2) (bpy=bipiridine) were synthesized by a sonochemical method and characterized by elemental analyses, thermal gravimetric analysis (TGA), differential thermal analysis (DTA), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The cry...
In this study a sensitive electrochemical sensor for the detection of E.coli has been developed using silver nanoparticle (Ag) embedded poly(9,9-dioctylfluorene-ran-phenylene) (CFP) nanocomposite as a conductive platform and DNA hybridization technique. The new polymer was synthesized from 9,9-dioctylfluorene and 1,3-dichlorobenzene and biphenyl through Friedel Crafts alkylation reacti...
copper sulfate was used as a precursor to prepare cuo nanoparticles in reverse micelles (o/w microemulsion). this is a technique which allows the preparation of ultrafine metal oxide nanoparticles within the size ranging from 50 to 60 nm. the preparation of nano copper (ii) oxide studied was investigated in the inverse microemulsion system. therefore the nucleation of metal particles proceeds ...
A solid phase extraction sorbent based on polyaniline/graphene nanocomposite is presented. The structure and morphology of synthesized nanocomposite were investigated by Fourier transform infrared spectroscopy, field emission scanning electron microscopy, X-ray diffraction and thermal gravimetric analysis. The dispersive solid phase extraction was employed to the isolation and preconcentration ...
the preparation of nanostructure type manganese oxide and cobalt oxide materials with the smallest particle size is reported here. the nanorod manganese oxide and cobalt oxide nanotube were prepared via a sol-gel reaction in reverse micelles from kmno4 and cocl2 with respectively source at room-temperature. the structure and surface morphology of the obtained manganese oxide were studied by mea...
Chitosan/montmorillonite nanocomposite films were prepared by the solvent evaporation method to immobilize drug ibuprofen (IBU) and delay its release in a medium that simulates environment of gastrointestinal tract. The effects montmorillonite, at different mass proportions (10, 20, 50%), on morphological physical properties studied. samples characterized X-ray diffraction (XRD), Infrared Spect...
In this study, isophthalic acid-zirconium(IV) nanocomposite has been prepared from zirconyl nitrate pentahydrate and potassium iodide, with isophthalic acid, (C8H6O4=Benzene-1,3-dicarboxylic acid) as a ligand, via sonochemical method in ethylene glycol and methanol as solvents. The crystalline tetragonal ZrO2 has been produced by thermal decomposition of isophthalic acid-zirconium(IV) nanocompo...
