Understanding how structure influences electronic properties in molecular films

Organic electronic materials based on small molecules have a range of interesting applications: they enable lightweight, flexible devices that can be biodegradable and very cheap to manufacture.One challenge working with small molecules controlling how they crystallise into a film, since this affects the electronic properties of the resulting device. Since a wide range of parameters affect the way the film crystallises, this can be a complex problem to understand and control.The aim of this project will be to investigate the …

Plasma additive (3D) and roll-to-roll (2D) manufacturing

Plasma printing technology is a rapidly emerging multidisciplinary research and development topic focused on the development of novel advanced technologies for additive manufacturing and 3D surface modification (3D printing) and roll-to-roll fabrication (2D printing) assisted by atmospheric-pressure low-temperature plasmas.The research on these technologies is based on customised physical, chemical, and biological effects of low-temperature plasmas.

2D heterostructures for future electronics

The traditional approach to the miniaturisation of electronic devices is coming to a halt. Experts agree that the Moore’s law prediction of doubling the number of transistors per chip every two years will cease to be fulfilled in 2020, as the heat produced in small structures cannot be cooled down quickly enough.However, by reducing the size of the device, the quantum nature of atoms and solids can be turned into an asset. By exploiting the phenomena occurring at these scales, …

Portable magnetic resonance imaging of biological tissues

Magnetic Resonance Imaging (MRI) provides a unique way of non-invasive investigation of the 3D organisation of biological tissues and materials.The physical basis of MRI is the intrinsic magnetism of atomic nuclei. The magnetic moment of a single atomic nucleus is extremely small and effectively undetectable. However, the collective magnetisation of nuclei in a macroscopic sample can be sufficiently large to be detected, especially in the case of nuclei that are abundant in the sample. This is the case in most …

Developing next-generation mass spectrometry imaging with isomer resolution

Mass spectrometry imaging (MSI) is a rapidly emerging technology for mapping molecular distributions within biological samples.This project will bring together market-leading MSI instrumentation from an industry partner, Waters Corporation, with unique technologies developed at QUT to develop an integrated MSI-platform capable of achieving high mass-resolution and spatial-resolution, as well as discrimination of lipid isomers.Resolution of lipid isomers using this instrumentation will afford researchers a first glimpse of isomer-resolved images that will be used to visualise tissue-specific changes resulting from underlying …

Pluses and minuses of lipid mass spectrometry

Lipids (fats) are an abundant and structurally diverse group of molecules with an equally diverse array of functions in cellular biology.This project will develop new analytical technologies - based on advances in mass spectrometry and ion chemistry - that enable the analyst to identify and quantify individual lipids present at low concentrations in biological mixtures comprising many thousands of distinct molecules.These new capabilities will drive the discovery of unknown lipids and map the complex biochemical pathways through which they are …

Smoke and mirrors: intercepting the elusive molecular precursors of soot

Air pollution is set to become the major environmental cause of premature death. In Australia, airborne smoke particles from anthropogenic and natural sources, including bushfires, present a particular risk to the population’s health. Despite its national importance, the fundamental chemical transformation of hot gases released during combustion to soot particles is poorly understood. In the absence of a chemical model for these gas-phase reactions it is challenging to predict or control the composition and concentration of particles released into the …

Metal polymer batteries and supercapacitors for renewable energy storage

Australia boasts rich wind and solar energy resources. To avoid fluctuations placing severe burden on the power grids, a reliable and efficient battery storage is required.The present technology based on lithium-ion batteries suffers from high manufacturing costs, poor safety and short life-span. Metal-polymer batteries are expected to overcome the storage and the charging speed of the traditional batteries in the near future, opening new avenues for renewable energy resources …
