Preparation and electrochemical corrosion behavior of bulk nanocrystalline ingot iron in HCl acid solution

Article Abstract:

Bulk nanocrystalline ingot iron (BNII) is produced by the severe rolling technique and the corrosion behaviors of BNII and as-received conventional polycrystalline ingot iron (CPII) in 1 M HCl solution are investigated by potentiodynamic polarization tests, electrochemical impedance spectroscopy measurement and immersion tests at room temperature. The anodic dissolution process is inhibited but the cathodic process is enhanced for BNII.

Modeling interband transitions in silver nanoparticle-fluoropolymer composites

Article Abstract:

The interband transition contributions to the optical properties of silver nanoparticles in fluoropolymer matrices are investigated. Nanoparticles synthesis within the existing polymer matrix is accomplished using an infusion process that consists of diffusing an organometallic precursor gas into the free volume of the fluoropolymer and decomposing the precursor followed by metal nanoparticle nucleation and growth.

Electrochemical self-assembly of highly oriented ZnO-surfactant hybrid multilayers

Article Abstract:

Highly oriented zinc oxide-surfactant hybrid multilayers are electrochemically self-assembled on silicon substrates from Zn(NO3)2 solutions containing extremely low concentrations of sodium dodecyl sulfate. It is implied from the results that the kinetics of the electrochemical self-assembly depends on the relative speed of the reduction of the zinc ions and the aggregation of the surfactant.
