Liesegang rings: nanoparticles ring the changes.


Liesegang rings are circular patterns formed by ions precipitating in well-defined areas, rather than a single place, of a gel. They are, however, formed by a relatively small number of combinations of species and supports. Most of the species are ionic and offer little chance to tune their properties such as size or solubility, so the rings are generally… (More)
