Transformability of LMMPs/LMNPs
Due to the high surface tension, the oxide-covered LMMPs/LMNPs are typically spherical. However, under
certain conditions, LM particles can be shifted into diverse shapes. These anisotropic nanoparticles possess
specific optical, electrical, and thermal properties . The shape transformation of LM particles could be
