Ag-Fe2O3 and Sn-doped Ag-Fe2O3 nanocomposite photocatalysts were optimized by scanning photoelectrochemical microscopy (SPECM) as a potential photoelectrochemical material for visible light irradiation (λ g 420 nm). The photocurrent vs potential response and the action spectra were investigated in a three-electrode cell. Among different mole ratios, the composition of nanocomposite with 50%Ag-5...

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 ...

Nanocomposite films of metal nitrides such as TiN/Si3N4, TiN/BN, and CrN/AlN have attracted substantial attention as coating materials for improving hardness and saving rare metals. It is difficult to prepare composite films consisting of nitride and oxide by conventional reactive sputtering methods. Nose et al. developed a differential pumping cosputtering (DPCS) system, which can fabricate di...

Combined plasmonic nanocrystals and metal–organic framework thin-films are fabricated for sensing gases in the near-infrared range. This nanocomposite thin-film shows a highly sensitive response in near-infrared absorption, which is attributed to preconcentration of gas molecules in metal–organic framework pores causing close proximity to the electromagnetic fields at the plasmonic nanocrystal ...

Osteoblast differentiation can be modulated by variations in order of nanoscale topography. Biopolymers embedded with carbon nanotubes can cause various orders of roughness at the nanoscale and can be used to investigate the dynamics of extracellular matrix interaction with cells. In this study, clear relationship between the response of osteoblasts to integrin receptor activation, their phenot...

The utility of polymer-metal nanocomposite thin films with in situ generated silver nanoparticles as substrates for surface-enhanced Raman scattering (SERS) is demonstrated. Thin films of poly(vinyl alcohol) and poly(vinyl butyral-co-vinyl alcohol-co-vinyl acetate) containing Ag nanoparticles generated in situ through thermal annealing and photoirradiation, respectively (Ag-PVA and Ag-PVVV), ar...

Advanced materials that are highly biocompatible and easily modifiable with biomolecules are of great importance for bio-interfacing and the development of biodevices. Here, a biocompatible conducting polymer based nanocomposite was electrochemically synthesized through the electropolymerization of poly(3, 4-ethylene dioxythiophene) (PEDOT) in the presence of graphene oxide (GO) as the only dop...

The effect of carbon nanotubes on polymer macromolecular orientation structure during stretching of syndiotactic polystyrene/carbon nanotube nanocomposite film was quantitatively studied for the first time by an infrared dichroism technique.

Over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (TFC) membranes. In advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (TFN) membranes. However, in the last generation of TFNs, an ultrathin selective film of nanoparticles is coated...

A novel Zr,Ce-TiO2/SiO2 nanocomposite thin film was successfully prepared with various amounts of Zr4+ and Ce4+ as codopant ions for self-cleaning applications. A thin film was coated on a tile substrate by dip-coating and porous Zr,Ce-TiO2/SiO2 was obtained after heat treatment for 2 hours at 500 °C. The SEM images an...
