Australia supplies 25 per cent of the world's pain relieving medicinal opiates which contributes to a $200 million export industry for Australia. The active pharmaceutical ingredients are extracted and purified at GlaxoSmithKline’s (GSK) Port Fairy processing plant using a solvent extraction based process. Together with GSK the project team aim to examine the use of environmentally sustainable bio-derived natural solvents to replace the volatile organic compound (VOC) fossil fuels based solvents used in the current process. Due to environmental and health concerns associated with VOCs the development of alternative solvents will be of great benefit to not only GSK but a range of other processing industries that also use VOC based solvent extraction processes.Read moreRead less

Nutrient deficiency undermines the potential of billions of people and many nations. The requirement is to rapidly increase micro-nutrient delivery to support intensive and fortified crop production. This proposal seeks to develop a controlled ion release system through the use of tailored suspensions of nano-crystal nutrient materials for delivery to plants through the leaves. This will increase yields from arable land, reduce water requirements and fertiliser applications, fortifying foods for better nutrition leading to improved human health and wellbeing. It leverages and applies recent significant advances in surface science and nanotechnology to gain improved outcomes in agriculture.Read moreRead less
Immune-imprinting nanoparticles (iNPs). This research promises new classes of immune-imprinting, biodegradable nanoparticles (iNPs) with anti-inflammatory properties.

The project aims to develop a new single-dose, room temperature-stable nanovaccine for cost-effective influenza poultry vaccination. The nanovaccine is based on viral protein assembly modularised to present multiple copies of influenza antigen. Particularly, this project focuses on the engineering of this vaccine manufacturing and formulation for a room temperature-stable vaccine. The resulting engineered vaccine would play an important role in preventing avian influenza outbreaks, which are currently affecting both developed and developing countries, costing millions of dollars due to the death and culling of infected poultry.Read moreRead less
The Development of New Carrier Technologies for Spray-Dried Fruit Extracts. This project aims to develop new carrier techniques for spray drying fruit extracts based on the use of natural fibres, with the aim of overcoming a key problem in the operation of spray dryers for producing powders, the deposition of particles on walls. Carriers are non-sticky materials that effectively dilute the stickiness of any materials. The significance is that it will use waste products from fruit processing (th ....The Development of New Carrier Technologies for Spray-Dried Fruit Extracts. This project aims to develop new carrier techniques for spray drying fruit extracts based on the use of natural fibres, with the aim of overcoming a key problem in the operation of spray dryers for producing powders, the deposition of particles on walls. Carriers are non-sticky materials that effectively dilute the stickiness of any materials. The significance is that it will use waste products from fruit processing (the fibres from skins) to overcome this problem, and it will also be possible to dry sticky materials using material from the fruit itself, rather than additives such as maltodextrin.Read moreRead less

Perfect particles: Accurate breakage predictions by 3D printing of granules. Granule breakage of micro-structured specialty products impedes manufacturing and degrades product performance. Predictive breakage models have had limited success as each granule has a unique structure. Differences between the model predictions and experimental breakage test results could be due to inaccurate models or irreproducible experimental results due to granule structure differences. This project is expected to ....Perfect particles: Accurate breakage predictions by 3D printing of granules. Granule breakage of micro-structured specialty products impedes manufacturing and degrades product performance. Predictive breakage models have had limited success as each granule has a unique structure. Differences between the model predictions and experimental breakage test results could be due to inaccurate models or irreproducible experimental results due to granule structure differences. This project is expected to be the first ever application of three-dimensional printing for reproducible breakage testing. The project aims to: create the first ever multiple identical copies of complex granules using polyjet three-dimensional printing; model and experimentally measure granule breakage; and develop sophisticated Digital Elevation Models of granule breakage for practical use in industry.Read moreRead less
