Preparation, characterization, and photoluminescence study of PVA/ZnO nanocomposite films
ZnO nanoparticles with average diameter of 25 nm were synthesized by a modified sol–gel method and used in the preparation of (in wt.%) (100 − x) poly(vinyl alcohol) (PVA)/x ZnO nanocomposite films,Expand
Entropy change linked to the magnetic field induced Morin transition in Hematite nanoparticles
The most stable form of iron oxide is Hematite (α-Fe2O3), which has interesting electronic, catalytic, and magnetic properties showing size dependent characteristics. At room temperature, Hematite isExpand
Synthesis and Characterization of Phosphated Crosslinked Chondroitin Sulfate: Potential Ingredient for Specific Drug Delivery
Because of its biodegradability several natural polymers, such as polysaccharides, have been proposed as appropriate excipients for the development of controlled drug delivery systems for oralExpand
Targeting cancer with nano-bullets: curcumin, EGCG, resveratrol and quercetin on flying carpets.
It is becoming progressively more understandable that different phytochemicals isolated from edible plants interfere with specific stages of carcinogenesis. Cancer cells have evolved hallmarkExpand
Synthesis and characterization of ZnO, CuO and a mixed Zn and Cu oxide
Abstract ZnO, CuO, and Cu0.05Zn0.95O nanoparticles have been prepared by a sol–gel method using poly(vinyl alcohol) aqueous solutions and metal nitrate precursors. The precursor powders were analyzedExpand
Thermal and photochemical stability of poly(vinyl alcohol)/modified lignin blends
Abstract A kraft lignin derivative (KLD) obtained by reaction with p -aminobenzoic acid/phthalic anhydride was blended with poly(vinyl alcohol) (PVA) by solution casting from DMSO. PVA and PVA/KLDExpand
Thermal and FTIR study of polyvinylpyrrolidone/lignin blends
SummaryLignin and poly(vinylalcohol) (PVA) solutions were separately prepared and then mixed in appropriate ratios, to yield the films after solvent (DMSO) evaporation. Two lignin samples were used:Expand
Co-doped ZnO nanoparticles synthesized by an adapted sol–gel method: effects on the structural, optical, photocatalytic and antibacterial properties
Abstract Pure and Co-doped ZnO nanoparticles were synthesized with different cobalt levels (1–10 mol%) via adapted sol–gel method using water as solvent and characterized by X-ray diffraction,Expand
Nanometric particle size and phase controlled synthesis and characterization of γ-Fe2O3 or (α + γ)-Fe2O3 by a modified sol-gel method
Fe2O3 nanoparticles with sizes ranging from 15 to 53 nm were synthesized by a modified sol-gel method. Maghemite particles as well as particles with admixture of maghemite and hematite were obtainedExpand
The Effects and Role of Polyvinylpyrrolidone on the Size and Phase Composition of Iron Oxide Nanoparticles Prepared by a Modified Sol-Gel Method
Fe2O3 nanoparticles (as maghemite and hematite mixtures) were prepared using adapted sol-gel method from a polyvinylpyrrolidone (PVP) aqueous solution in various Fe3
