Peroxidase has been immobilized onto the PVA-PANI nanocomposite film deposited onto gold plate via physical adsorption for peroxide detection. PVA-PANI nanocomposite was characterized by scanning electron micrograph (SEM) before and after immobilization. The SEM picture clearly shows the immobilization of peroxidase onto the PVA-PANI. The cyclic voltametric study is also carried out for the as ...

We demonstrate the one-step synthesis of a silica-gold nanocomposite by simultaneous hydrolysis and reduction of gold chloride. The aminophenyl group was used as a reducing agent, and the trimethoxy silane group acts a precursor for the formation of silica. The porous gold nanoparticles were formed by etching out the silica-gold nanocomposite by hydrofluoric acid. The electron diffraction of po...

Silane modified iron (III) oxide (SiFe2O3) nanoparticles reinforced chitosan (CS) nanocomposite membranes were prepared by solcast transformation method. The iron (III) oxide nanoparticles and nanocomposite membranes were investigated by UV (Visible) spectroscopy, FT-IR spectroscopy, XRD, SEM and TEM. The size and shape of iron (III) oxide and Si-Fe2O3 nanoparticles were determined by XRD and T...

Microstructured composite beams reinforced with complex three-dimensionally (3D) patterned nanocomposite microfilaments are fabricated via nanocomposite infiltration of 3D interconnected microfluidic networks. The manufacturing of the reinforced beams begins with the fabrication of microfluidic networks, which involves layer-by-layer deposition of fugitive ink filaments using a dispensing robot,...

S. Ponmani and C. Udayasoorian Abstract -A new class of nano scale zero valent iron (nZVI) particles supported on activated carbon (AC) were synthesized and the feasibility of using nanocomposite (AC+nZVI) for the removal of Cr(VI) in water was investigated through laboratory batch test. Nanocomposite was synthesized by impregnating carbon with ferrous sulfate followed by chemical reduction wit...

A novel nanocomposite has been developed using extracted cellulose from marine algae coated with conductive polypyrrole and graphene nanoplateletes. The nanocomposite fabricated via in situ polymerization was used as an electrode for a supercapacitor device. The nanocomposite material has been electrochemically characterized using cyclic voltammetry to test its potential to super-capacitive beh...

Two types of Aluminum nitride (AlN) based ceramic nanocomposite with multifunctionality were investigated to improve machinability or electrical conductivity of AlN ceramics with high thermal conductivity. The AlN/BN nanocomposite was fabricated by pressureless sintering AlN-BN composite powder, which was prepared by reducing and heating AlN particles coated with a mixture of boric acid, urea a...
