Carbon Quantum Dots: Elegant Surface of CoNi Alloys toward Efficient Magnetorheological Performances Realized with Carbon Quantum Dots (Adv. Mater. Interfaces 15/2018)

Abstract

A series of CoNi based hierarchical microspheres with different surface morphologies, including litchi-like, seed of plane tree-like and waxberry-like shapes, are obtained via surface nucleation of carbon quantum dots (CQDs). Taking both the synergistic benefits of paramagnetic CoNi microspheres and surface architecture, the resulting CoNi microspheres exhibit enhanced interparticle friction for enhancing their MR effects compared with smooth surface microspheres.
