Chemistry in Pictures: Tiny tessellation

There’s something retro about Felipe Quiroga-Suavita’s anisotropic nanocrystals—a fancy name for nanoparticles that grow faster in some directions than others. Usually chemists create geometric crystals like these by capping some crystal edges with organic molecules. Those molecules slow the growth of the crystals at those edges. The other faces thus grow more quickly and in an orderly fashion, making well-defined polygons. In the long term, Quiroga-Suavita, a PhD student working with the National Institute of Applied Sciences (INSA) of Toulouse and the University of New South Wales Sydney, wants to investigate how a nanoparticle’s form changes its optical, catalytic, and magnetic properties.
