Tuning size and shape of gold nanoparticles using seed-mediated growth by unfocused femtosecond laser-induced plasma.

Gold nanoparticles with tunable size and shape are effectively synthesized with a femtosecond laser using the seed and growth method by reducing a KAuCl solution with polyvinylpyrrolidone (PVP) surfactant as a stabilizer. The sizes of gold nanoparticles, including 7.30 to 9.

Effect of Heat Treatment on Structural, Magnetic and Electrical Properties of LaFeMnO.

In this study, the effect of heat treatment on the structural, magnetic and electrical properties of LaFeMnO prepared via the sol-gel and sintering method were investigated. The heat-treatment conditions, i.e.
