Biography
Joshua Hammons has expertise in small angle scattering and electrochemical techniques. Specific to small angle scattering, much of his work is devoted to removing model ambiguity by simultaneously performing other measurements or by changing the sample geometry. This approach is applied to nanoparticle stability, assembly and synthesis in deep eutectic solvents where complex inhomogeneities are observed. These solutions are a unique scattering system, as they contain very soft perturbations that can be induced by surface charging and/or adsorption. In the presence of nanoparticles, the deep eutectic solvent is significantly perturbed far from the particle surface. Other research interests include nano-second small angle scattering to study rapidly evolving systems, such as high explosives and nanoscale kinetics.
