The octa-functionalized polyhedral oligomeric silsesquioxane (POSS) containing nanocomposites of epoxy resin are prepared via in situ co-polymerization of epoxy resins with 4,4’-diaminodiphenylsulfone (DDS) in the presence of octaaminophenyl silsesquioxane (OAPS). Two of the most common, technologically relevant epoxy resins, diglycidyl ether of bisphenol-A (DGEBA) and tetraglycidyl diamino dip...

Nanocomposites of poly(3-hexylthiophene) (P3HT) and nitrogen-doped carbon nanotubes (N-CNTs) have been synthesized by two methods; specifically, direct solution mixing and in situ polymerization. The nanocomposites were characterized by means of transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray dispersive spectroscopy, UV-Vis spectrophotometry, photoluminescence ...

In the present study, Mg (1.98 and 2.5) vol % TiO₂ nanocomposites are primarily synthesized utilizing solid-phase blend-press-sinter powder metallurgy (PM) technique and liquid-phase disintegrated melt deposition technique (DMD) followed by hot extrusion. Microstructural characterization of the synthesized Mg-TiO₂ nanocomposites indicated significant grain refinement with DMD synthesized Mg nan...

Biodegradable polymer-ceramic composites offer significant potential advantages in biomedical applications where the properties of either polymers or ceramics alone are insufficient to meet performance requirements. Here we demonstrate the highly tunable mechanical and controlled drug delivery properties accessible with novel biodegradable nanocomposites prepared by non-covalent binding of sili...

A series of 0-3 metal oxide-polyolefin nanocomposites are synthesized via in situ olefin polymerization, using the following single-site metallocene catalysts:C2-symmetric dichloro[rac-ethylenebisindenyl]zirconium(IV),Me2Si( BuN)(η-C5Me4)TiCl2, and (η -C5Me5)TiCl3 immobilized onmethylaluminoxane (MAO)-treated BaTiO3, ZrO2, 3-mol%-yttria-stabilized zirconia, 8-mol%-yttria-stabilized zirconia, sp...

Polyethylene/chrysotile nanocomposites with different amount (0.4 to 6.7 wt%) of filler were prepared by in situ polymerization method using the metallocene Cp2ZrCl2 as catalyst and methylaluminoxane (MAO) as co-catalyst. Previous to polymerization, raw chrysotile was treated by three different methods that used thermal treatment and acid leaching. In method A, raw chrysotile was treated therma...

The enhanced biological and degradation properties of bioresorbable polymer matrix nanocomposites intended for use in orthopaedic applications have been demonstrated recently. However, at the moment there are only limited reports addressing their mechanical properties under physiological conditions, which is of central importance to the successful design of these nanocomposites. Here, we show t...

Anisotropic yolk/shell or Janus inorganic/polystyrene nanocomposites were prepared by combining miniemulsion polymerization and sol-gel reaction. The morphologies of the anisotropic composites were found to be greatly influenced by surface modification of zinc oxide (ZnO) nanoparticle seeds. Two different types of the oleic acid modified ZnO nanoparticles (OA-ZnO) were prepared by post-treatmen...

Treatment of malignancies on the chest wall, like chest wall recurrence of tumor, advanced cutaneous neoplasm and lymphoma, is still a challenge due to the involvement of the critical structures of heart and lung by the conventional strategy. The aim of the current study was to investigate targeted photo-chemo therapy mediated by Fe3O4@ZnO nanocomposites for malignancy on the chest wall while c...
