The primary focus of research in the Pozzo group centers on the development, measurement and control of self-assembly processes for colloidal materials over nanometer and micrometer scales. This manipulation of complex material structures results in novel properties that optimize their use in engineering applications.

Conductive Polymers: Gels, crystals, nanowires and nanoparticles assembled from conductive conjugated polymers are used for applications in solar energy, batteries and specialty industrial paints. Neutron scattering tools are being used to experimentally validate computational models that can describe these systems. Improved force fields and simulations accelerate the synthesis of conductive polymer systems with peak performance.

Energy Research: New nanomaterials are being developed for high capacity and low cost energy storage to accelerate the electrification of our society and the adoption of clean energy technologies. Current efforts include the synthesis of low-cost membranes for large-scale flow battery systems that maximize proton conductivity while minimizing ion crossover. Self-assembled organometallic micellar structures also enable electrochemical reactions in organic solvents that could significantly increase cell potential and improve safety.

Medical Agents: Nanosized ‘Armored’ emulsions containing an interfacial layer of near-infrared (NIR) absorbing nanoparticles are being developed to enable high-resolution and low-cost medical imaging technologies. Emulsion contrast agents undergo a phase transition from liquid to vapor upon irradiation with NIR laser light. The rapid thermal expansion of the vapor bubble produces a pressure wave that is picked up by an ultrasound transducer to be transformed into an image. The pressure wave can also be used for thrombolysis, the mechanical destruction of an occlusion (clot) inside blood vessels.
