Coexistence of ergodicity and nonergodicity in LaFeO3-modified Bi(1/2)(Na(0.78)K(0.22))(1/2)TiO3 relaxors.

The effect of LaFeO(3) addition to Bi(1/2)(Na(0.78)K(0.22))(1/2)TiO(3) ceramics on the phase stability and macroscopic functional properties was investigated.

Enhancement in corrosion barrier properties of polyurethane films on steel by embedding MgO nanoparticles.

The effect of nanosized MgO loading on the corrosion barrier characteristics of polyurethane (PU) films on mild steel has been investigated. It was found that small amount of MgO loading even as low as 0.03 vol% significantly improved the corrosion retardation ability of PU films.
