Using anisotropic thermal expansion in organic semiconductor thin films. This project aims to capitalise upon the recent discovery of negative thermal expansion in high-performance organic semiconductor films. Certain molecules’ chemical structures have a planar conjugated core and flexible sidechains. When highly anisotropic thermal expansion occurs, the sidechains take up most of the thermal expansion. When a negative thermal expansion occurs, the pi-pi stacking distance decreases upon anneali ....Using anisotropic thermal expansion in organic semiconductor thin films. This project aims to capitalise upon the recent discovery of negative thermal expansion in high-performance organic semiconductor films. Certain molecules’ chemical structures have a planar conjugated core and flexible sidechains. When highly anisotropic thermal expansion occurs, the sidechains take up most of the thermal expansion. When a negative thermal expansion occurs, the pi-pi stacking distance decreases upon annealing. This effect has been linked with higher charge mobilities, and a tighter molecular packing is locked in upon cooling. The potential applications of these high performance organic semiconductors includes chemical/biosensors, electronic paper, and radio frequency identification cards.Read moreRead less
Bioelectronics: addressing the biointerface challenge. This project aims to develop bioelectronic materials with long operational stability in physiological conditions and enhanced electronic performance that will effectively interface with electroresponsive tissue. These new materials will be integrated into bioadhesives from which simple bioelectronics devices will be fabricated and assessed for their capability to modulate biosignals and to interact with tissue.

This project aims to develop bioelectronic materials with long operational stability in physiological conditions and enhanced electronic performance that will effectively interface with electroresponsive tissue. These new materials will be integrated into bioadhesives from which simple bioelectronics devices will be fabricated and assessed for their capability to modulate biosignals and to interact with tissue. Disruption in biosignals causes numerous medical conditions such as epilepsy and heart failure and the development of flexible and biocompatible medical electronics devices that interface with tissue is essential for regaining and modulating these signals.Read moreRead less
Non-polyamide-based polymer membranes for efficient water processing. This project aims to develop an innovative, two-dimensional nanosheet scaffold polymerisation technique for the fabrication of advanced membranes. Membrane technology plays a key role in wastewater treatment and water desalination and purification. However, current membranes are not stable in an oxidation environment such as chlorine, which leads to significant membrane replacement costs. Through the development of new membran ....Non-polyamide-based polymer membranes for efficient water processing. This project aims to develop an innovative, two-dimensional nanosheet scaffold polymerisation technique for the fabrication of advanced membranes. Membrane technology plays a key role in wastewater treatment and water desalination and purification. However, current membranes are not stable in an oxidation environment such as chlorine, which leads to significant membrane replacement costs. Through the development of new membrane fabrication technology the project aims to produce non-polyamide-based polymer membranes with outstanding oxidation tolerance and separation properties. This will potentially simplify membrane processes, and improve water processing efficiency in wastewater treatment for power generation, and clean drinking water production.
