synthesis, characterization and thermal study of poly (methyl methacrylate)-co3o4 nanocomposite film
nanosized metal oxides dispersed polymer composites constitute a fascinating class of polymer composite materials. synthesis of such composite materials through solvent casting enhances the polymer synthetic technology. solvent casting method was used to prepare cobalt oxide (co3o4) dispersed poly (methyl methacrylate) (pmma) nano composite. x-ray diffraction tool is used to know the structural...
the in vitro dissolution of plasma-sprayed hydroxyapatite (pha) coatings with different characteristics, produced by various spraying conditions, in a tris-buffered solution at ph 7.4 was experimentally studied through the measurement of calcium ions release with inductively coupled plasma atomic emission spectroscopy (icp-aes), and then modeled. three coating characteristics, the crystallinity...
The aim of this work was to identify parameters that could influence the conversion kaolinite into metakaolinite. To end, dehydroxylation four kaolinites, using controlled rate thermal analysis (CRTA) and thermogravimetric (TGA), investigated. X-ray diffraction (XRD) Fourier transform infra-red (FTIR) were used confirm kaolinitic nature samples. Their crystallinity evaluated Hinckley index from...
Herein, we have investigated the optical and microwave dielectric properties of Bi0.5Na0.5TiO3 (BNT) thin films grown under different oxygen pressure (PO2) using pulsed laser deposition technique. The X-ray diffraction measurements confirm single phase BNT secondary a further reduction in increase with PO2, which signifies close relationship between crystal structure content. shift Raman-active...
this study is devoted to the morphological, chemical and physical characterization of raw material of the fruit of luffa cylindrica. by microscopic analysis, it can be observed that the fruit is composed of an assembly of dependent cords, where four parts are differentiated: external, internal wall, core and bond. each cord consists of hollow and flexible cylindrical fibers.the external part is...
Waste hemp and flax fibers, cotton cotton/polyester yarns, available in large quantities from the textile industry, were used as cheap effective sorbents for removal of methylene blue wastewater. fibers yarns characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, iodine sorption, water retention, point zero charge, well through determination crystallinity index ...
The crystallinity of cadmium titanate (CdTiO3) was greatly improved when synthesized under mild reaction conditions, in the presence of chloride. The highly crystalline CdTiO3 showed much enhanced photodegradation of methyl orange (MO) under simulated sunlight. CdTiO3 was characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS),...
