Exchange-coupling soft magnetic FeNi-SiO2 nanocomposite
Article Abstract:
A method to make exchange-coupled soft magnetic FeNi-SiO2 nanocomposite material composed of FeNi nanoparticles coated with a thin SiO2 layer is reported. It is observed that up to at least 100 MHz permeability is independent of frequency, with value as high as 16 in samples with density 93% of the ideal quality.

Acid doping of polyaniline: spectroscopic and electrochemical studies
Article Abstract:
Results show that fundamental differences exist in the acid doping behavior of polyaniline film between a strong and a weak acid. Data indicate that both protons and anions of the dopant acids influence the structure and redox properties of polyaniline.
