| Abstract Scope |
This talk will describe theory that can be used to understand metal particles going from mining to optical devices. We begin by describing a recent collaboration with Fraser Stoddart’s group concerned with making supramolecular structures for gold recovery based on binding of gold ions with cucurbit[6]uril anions. Several Au3+ salts bind to these anions in solution, leading to precipitates that enable 99.2% gold recovery. Theory can be used to rationalize the solubility properties of the precipitates, and depends on the anion associated with Au3+.We then move to bimetallic nanoparticles, in particular gold/nickel bimetallics that are made using scanning probe block copolymer lithography (SPBCL) (in studies by the Chad Mirkin group) and other techniques that lead to Janus-like structures. Finally we describe studies of arrays of gold nanoparticles, and plasmonic lattice resonances associated with these arrays that enable powerful control of optical properties in many different ways. |
