Engineering better sprays for leaf coating: from drop impact to retention. This proposal aims to understand the performance of a unique rheological modifier that can enable an order of magnitude increase in coating efficiency for aerosol sprays while not affecting the quality of droplet formation during spraying. The effect occurs via a dispersed network of fibrous particles in water, providing a weak but useful ability to coat surfaces by responsively adjusting its structure.

This proposal aims to understand the performance of a unique rheological modifier that can enable an order of magnitude increase in coating efficiency for aerosol sprays while not affecting the quality of droplet formation during spraying. The effect occurs via a dispersed network of fibrous particles in water, providing a weak but useful ability to coat surfaces by responsively adjusting its structure. The material is expected to enable a broad array of applications, from agricultural treatments to nasal sprays, by exhibiting responsive behaviour at concentrations much lower than conventional modifiers require. The project will study the responsiveness of the system in single droplet, spray, and coating form as well as an active delivery system.Read moreRead less

Rational Design of Hematite Photoanodes for Solar Hydrogen Generation. Hematite (iron oxide) is a promising electrode material for photoelectrochemical hydrogen generation from water. It has low cost, good long-term stability and absorbs light efficiently. However, its use is limited by its poor electrical conductivity.

Hematite (iron oxide) is a promising electrode material for photoelectrochemical hydrogen generation from water. It has low cost, good long-term stability and absorbs light efficiently. However, its use is limited by its poor electrical conductivity. This project aims to develop a novel host-guest nanostructure that exploits the beneficial light-absorption properties of hematite (the guest) but shifts the charge transport function to a nanostructured transparent conductive oxide host. The project aims to produce nanostructured hematite electrodes for efficient hydrogen production from water and sunlight, thus making a significant contribution to the goal of commercially-viable storage of solar energy in the form of hydrogen.Read moreRead less
