Nitride materials: In the “bond ionicity Goldilocks zone” for solar energy. Progress towards commercial devices for solar-driven hydrogen generation as well as in-situ electricity generation for vehicles is currently hampered by a lack of earth-abundant, stable, non-toxic semiconductor materials that can be fabricated by scalable methods.

Progress towards commercial devices for solar-driven hydrogen generation as well as in-situ electricity generation for vehicles is currently hampered by a lack of earth-abundant, stable, non-toxic semiconductor materials that can be fabricated by scalable methods. This project aims to develop the first scalable solution synthesis methods for a new class of earth-abundant Zn-based nitride semiconductor nanocrystals that have favourable bond ionicity and establish their optoelectronic properties for renewable energy devices for the first time. Flexible solution processing methods will be exploited to tune surface composition, remove defects and create devices to achieve optimised performance in these challenging new nitride material systems.Read moreRead less

Molecular definition of cellular states in the vascular endothelium. The endothelium is the main cell type forming blood vessels and spans across multiple cell states from stem/progenitor to a variety of terminally differentiated cells. How each of these cell states are defined at the molecular level is not known preventing the optimal formation and integration of blood vessels in bioengineered tissues. Using innovative single cell gene expression and chromatin accessibility studies combined wit ....Molecular definition of cellular states in the vascular endothelium. The endothelium is the main cell type forming blood vessels and spans across multiple cell states from stem/progenitor to a variety of terminally differentiated cells. How each of these cell states are defined at the molecular level is not known preventing the optimal formation and integration of blood vessels in bioengineered tissues. Using innovative single cell gene expression and chromatin accessibility studies combined with innovative analysis, we propose to define and validate each cell state at the molecular level.
This new knowledge would greatly enhance our ability to control the transition between cell states leading to a more widespread use of endothelial cells in bioengineering of tissues globally for many applications.

The integration of functional molecular materials with inorganic systems remains an outstanding hurdle to achieve durable, highly efficient optoelectronic devices. This project aims to develop and understand this new class of devices, with a focus on directional energy transfer processes across hybrid interfaces. This project expects to generate new knowledge in photovoltaics (PV) and for organic light emitting diodes (OLEDs) by studying triplet transfer in two model systems. The first will be a step towards the development of advanced PV devices using down-conversion to push solar cells beyond the efficiency barrier. The second will demonstrate inorganic-organic solid state up-conversion for next generation OLEDs with improved stability.Read moreRead less
