Nb doped multiferroic BiFe1-xNbxO3 (0 〈x 〈0.05) polycrystalline powders have been syn-thesized by using a sol-gel method. The effect of Nb dopant on the structural, magnetic and optical properties is investigated....
Bamboo-structured boron nitride (BN) nanotubes with thorn-like morphology were synthe-sized by thermal chemical reaction using amorphous boron powders and NiO nanoparticles as precursors under the flow of NH3 at 110...
