Non-equilibrium presolvation electron processes at the gas-liquid interface. The interaction of low-temperature plasma electrons with liquids has served as a reducing agent in various technological applications in water treatment, agriculture, biofuels and medicine.

The interaction of low-temperature plasma electrons with liquids has served as a reducing agent in various technological applications in water treatment, agriculture, biofuels and medicine. Predictive control of the plasma-liquid interface is essential to unlocking the potential of these applications, and this has been limited by the absence of the relevant non-equilibrium transport theory describing electrons at the plasma-liquid interface together with fundamental data describing electron interactions with liquids. The project will develop a state of the art presolvation electron transport model informed by world first measurements of electron cross-sections for radicals and liquids and apply it to model plasma electrochemistry processes.Read moreRead less

Finding the missing links in salt and water transport in plants. Grain crops and horticultural plants use proteins called aquaporins to move water across cell membranes, but a group of these proteins can also transport some important nutrient ions as well as toxic sodium ions. This project aims to reveal the molecular pathways that regulate water and ion transport via aquaporins using advanced techniques in biophysics and molecular biology. These results will provide novel insights into how plan ....Finding the missing links in salt and water transport in plants. Grain crops and horticultural plants use proteins called aquaporins to move water across cell membranes, but a group of these proteins can also transport some important nutrient ions as well as toxic sodium ions. This project aims to reveal the molecular pathways that regulate water and ion transport via aquaporins using advanced techniques in biophysics and molecular biology. These results will provide novel insights into how plants coordinate and adapt to changing water and salt conditions, addressing a missing link in how ions and water move in and out of plant vacuoles.

Current dominant system architectures for terahertz waves are adapted from other ranges, leading to critical bottlenecks. This project will address this with a new integration platform that is tailored to the particular needs of terahertz waves. This requires advances in the emerging field of micro-scale integrated optics, combined with antenna-theory principles, semiconductor science, and advanced microfabrication to incorporate active devices. Novel spatially-dependent dispersion engineering techniques will also be pioneered for phased-array-free beamforming. This will enable a broad variety of all-in-one handheld systems for practical applications of terahertz waves such as noninvasive standoff sensing and self-aligning wireless links.Read moreRead less
