Comparative Studies on the Interaction of ‎Proteinase-K with Fe2O3, Fe3O4 and SiO2 ‎Nanoparticles

   The interaction of Fe2O3, Fe3O4 and SiO2 nanoparticles with proteinase K activity was investigated using UV–vis spectroscopy. Proteinase K EC (3.4.21.14) is a member of serine protease family, which is produced from fungus Tritirachum album Limber.The effects of nanoparticles on proteinase...

Hexagonal nanoplates of NiO/CoO/Fe2O3 composite acting as an efficient photocatalytic and electrocatalytic water oxidation catalyst.

A unique hexagonal sheet-shaped NiO/CoO/Fe2O3 composite with irregularly shaped nanoparticles was fabricated for the first time through a simple co-precipitation and hydrothermal method. The NiO/CoO/Fe2O3 composite was characterized by numerous techniques (TEM, HRTEM, PXRD, EDX, ICP-AES, BET, and XPS) to confirm its structure and composition. This structure of the NiO/CoO/Fe2O3 composite may en...

Antiferromagnetic proximity effect in epitaxial CoO/NiO/MgO(001) systems

Magnetic proximity effect between two magnetic layers is an important focus of research for discovering new physical properties of magnetic systems. Antiferromagnets (AFMs) are fundamental systems with magnetic ordering and promising candidate materials in the emerging field of antiferromagnetic spintronics. However, the magnetic proximity effect between antiferromagnetic bilayers is rarely stu...

Fluoride adsorption on γ − Fe2O3 nanoparticles

BACKGROUND Fluoride contamination of groundwater, both anthropogenic and natural, is a major problem worldwide and hence its removal attracted much attention to have clean aquatic systems. In the present work, removal of fluoride ions from drinking water tested using synthesized γ-Fe2O3 nanoparticles. METHODS Nanoparticles were synthesized in co-precipitation method. The prepared particles we...
