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

Transformational lighting: changing the way we live. This Fellowship aims to advance the science of ultrathin efficient lighting technologies based on low embedded energy organic light-emitting diodes (OLED). By creating innovative semiconductor materials and diode architectures that optimise each step in light generation—from charge injection, transport and capture to light emission—the project aims to deliver transformative OLED lighting that is more efficient than standard fluorescents by 50%. The intended outcomes of the project are design rules for OLED componentry, including thin, flexible architectures for deployment in a range of environments.

Thallium hydride complexes - synthesis, stabilisation and synthetic utility. Australia has abundant geological deposits of group 13 metals. The hydride chemistries of group 13 elements are critical to modern applications of these elements. There are no hydrides of thallium, the heaviest member of group 13. This project aims to prepare and stabilise thallium hydrides to enable technological applications of thallium.

This project aims to create a collaborative research facility for the microscopy and characterisation of nanometre structured devices and materials, enabling researchers to visualise and quantify the topography, chemical composition and structure of samples with a resolution approaching the atomic scale. A WiTek Alpha300SR microscope is capable of simultaneous atomic force microscopy, near-field scanning optical microscopy, photocurrent mapping, and Raman spectroscopy. These capabilities would allow the mapping of topography and chemical composition, response to optical stimulus, and the structure of materials in 3-D with nanometre-scale resolution on surfaces. This instrument would support research in areas such as organic photovoltaics, nanofabrication, polymer electronics, ionic fluids, functional interfaces, and thermionic devices.Read moreRead less

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.
