Abstract Herein, we present a detailed study of the structural, optical, and electrochemical responses Gd 2 O 3 doped with nickel zinc ferrite nanoparticles. Doping Ni 0.5 Zn Fe 4 nanoparticles to powder was done through thermal decomposition at 1000 °C. The average grain size mixture determined be approximately 95 nm, phases cubic , GdO, orthorhombic prisms GdFeO were identified. focused ion b...

forest cover is one of the most effective factors in reducing flooding in northern iran, so that in recent years the destruction, land use changing and uncontrolled harvesting of forest areas, has greatly increased the number and magnitude of floods. so far, there have been few studies on forest hydrology in iran, particularly the northern hyrcanian forests. this study examines the impact of a ...
