Nanoporous carbon matrix was prepared by the sol–gel process from pyrogallol-formaldehyde (PF) mixtures in water using picric acid as catalyst. For second sample, nickel oxide nanoparticles were added PF to get a PF/NiO hybrid organic/inorganic nanocomposite. After drying step, samples heat treated for two hours at 650 °C tubular furnace under open nitrogen atmosphere. The XRD analysis shows th...

Among the conducting polymers, polyaniline (PANI) and polypyrrole (PPy) are the most popular. According to the Web of Science, more than 10,000 papers appeared in the past 30 years on various aspects of chemistry, physics, and engineering of PANI. This is due to the cheapness and easy availability of raw materials, ease of synthesis, good environmental stability, high electrical conductivity an...

The synthesis and analysis of inorganic material combinatorial libraries by a directed-sorting, split-pool bead method was demonstrated. Directed-sorting, split-pool, metal-loaded libraries were synthesized by adsorbing metal salts (H2PtCl6, SnCl2, CuCl2, and NiCl2) and metal standards (Pt, Cu, Ni in HCl) onto 2-mg porous gamma-alumina beads in 96- or 384-well plates. A matrix algorithm for the...

This research aimed to evaluate the thermal properties of new formulations of phase change materials (PCMs)-epoxy composites, containing a thickening agent and a thermally conductive phase. The composite specimens produced consisted of composites fabricated using (a) inorganic PCMs (hydrated salts), epoxy resins and aluminum particulates or (b) organic PCM (paraffin), epoxy resins, and copper p...

Polymer based nanocomposites, in which inorganic nanoparticles are dispersed in organic polymer matrices, have attracted materials scientists’ attention owing to their unique properties, resulting from their nano-scale microstructure. Because of their large surface area, nanoparticles interact with the polymer matrix and carry a load effectively. The mechanical properties of these composites ca...
