Synthesis and characterization of nanostructured wires (1D) to plates (3D) LiV3O8 combining sol-gel and electrospinning processes.

Using the combined techniques of sol-gel and electrospinning, nanostructures (wire (1D) to plates (3D)) of LiV3O8 are prepared with poly vinyl alcohol (PVA) as the template. A precursor gel of LiOH-V2O5 is prepared in alkaline medium. Fibrous membranes of PVA with different weight% of LiOH-V2O5 gel are prepared by electrospinning and designated as PVA/LiOH-V2O5 composite membrane fibers.

Synthesis and characterization of processable multi-walled carbon nanotubes-sulfonated polydiphenylamine graft copolymers.

Water soluble and processable nanocomposites composed of multi-walled carbon nanotubes (MWNTs) and poly(diphenylamine sulfonic acid) (PDPASA) are synthesized and characterized. Two types of methodologies are adopted. MWNTs are covalently functionalized with 2,5-diaminobenzene sulfonic acid (DABSA) and further in situ polymerized with diphenylamine-4-sulfonic acid (DPASA).

Fabrication and electrocatalysis of self-assembly directed gold nanoparticles anchored carbon nanotubes modified electrode.

A self-assembly directed approach was adopted to modify glassy carbon electrode (GC) with gold nanoparticles incorporation and the electrocatalytic performance of self-assembly modified electrode, GC/SA-Au-ME was critically evaluated for the oxidation of ascorbic acid (AA). The modification involves the dispersion of multi-wall carbon nanotube (MWNT) and an inclusion complex, beta-cyclodextrin-4-aminothiophenol on the surface of GC electrode in the presence of cetyltrimethylammonium bromide (CTAB). Gold nanoparticles were deposited into the self-assembled sites to fabricate the modified electrode, GC/SA-Au-ME.
