Metal Nanoparticles Can Have Dipoles
The Pauling paradigm of chemical bonding holds that molecules made of identical atoms do not have ionic character. But a theoretical study from Donald G. Truhlar and Kaining Duanmu of the University of Minnesota, Twin Cities, shows that, in fact, metal nanoparticles actually can develop uneven charge distributions (J. Phys. Chem. C 2014, DOI:10.1021/jp511055k). Such particles can contain patches of partial . . .
