This work demonstrates the synthesis of core-shell ZrO2/PAAEM/PS nanoparticles through a combination of sol-gel method and emulsifier-free emulsion polymerizaiton. By this method, the modified nanometer ZrO2cores were prepared by chemical modification at a molecular level of zirconium propoxide with monomer of acetoacetoxyethylmethacrylate (AAEM), and then copolymerized with vinyl monomer to fo...

In this work, a reaction coupling self-propagating high-temperature synthesis (RC-SHS) method was developed for the in situ controlled synthesis of novel, high activity TiB2/(TiB2-TiN) hierarchical/heterostructured nanocomposites using TiO2, Mg, B2O3, KBH4 and NH4NO3 as raw materials. The as-synthesized samples were characterized using X-ray diffraction (XRD), scanning electron microscope (SEM)...

BACKGROUND The aim of present study was to develop the novel methods for chemical and physical modification of superparamagnetic iron oxide nanoparticles (SPIONs) with polymers via covalent bonding entrapment. These modified SPIONs were used for encapsulation of anticancer drug doxorubicin. METHOD At first approach silane-grafted magnetic nanoparticles was prepared and used as a template for ...

Silver nanostructures as an effective antibacterial materials were synthesized via three various hydrothermal, sono-chemical and microwave methods using water as a green solvent. Then Chitosan-Ag polymer based nanocomposites were made by a fast chemical procedure. The influence of power, temperature and time on the morphology and particle size of the products was investigated. Scanning electron...

In this research we first synthesized MgFe2O4 nanostructures via hydrothermal method using (Mg(NO₃)₂.6H₂O) and (Fe(NO₃)₃.9H₂O). The influence of concentration, surfactant, precipitating agent and temperature on the particle size and magnetic properties of the synthesised nanoparticles were examined. Then MgFe2O4-Ag nanocomposites were prepared by a simple chemical precipitation. The structural ...

poly(styrene-co-butyl acrylate)/clay nanocomposites were synthesized via in situ atom transfer radical polymerization using activators generated by electron transfer in the presence of a montmorillonite ion-exchanged with mixed surfactants of dodecyl trimethyl ammonium bromide and vinyl trimethyl ammonium chloride. the living nature of polymerization is confrmed by occurrence of narrow molecula...

Recently, composites of metal matrix attracted many researchers in mechanical, biomedical, chemical, and electrical fields due to its structure, thermal, some interesting chemical properties. Nanocomposites NiO/SiO2 NiO-Pr2O3/SiO2 considered much interest wide range applications medical, engineering, physics, chemistry, material science. In the present work, synthesizing nanocomposites was carr...

In this work, a novel route to synthesize polymer/metal composite nanospheres has been proposed. This method combines the advantages that the polymer chains collapse and entangle in the presence of compressed CO(2), which acts as antisolvent, and the metal nanoparticles and polymers can be precipitated simultaneously from micellar solutions by the easy control of CO(2) pressure. Ag/polystyrene ...
