Understanding and developing Kombucha SCOBY for the production of leather replacements

There is now significant interest and a strong drive to create functional equivalents for animal derived products that do not involve the use of animals. There have been some recent high profile examples of technologies to replace milk and meat and leather is also receiving attention.QUT, working with the State Library of Queensland, has been researching the use of Kombucha SCOBY (fermented tea cultures) to generate cellulose that when dried can resemble leather using a traditional Kombucha process.Related articlesModern Meadow …

He-ART (Heart Adaptive Radiation Therapy): Automated contouring and adaptive radiotherapy for the heart

Myocardial infarction is one of the proven cardiotoxic effects caused by incidental irradiation of the heart in patients with breast and lung cancer treated with radiotherapy (Darby et al 2013, van den Bogaard et al 2017, Bradley et al 2015). A clear dose-effect relationship was observed: the higher the dose of the incidental radiation to the heart, the higher the likelihood of a cardiovascular complication, such as a heart attack (Darby et al 2013, Wang et al 2017).These cardiotoxic effects …

Turning waste into value using biotechnology

Waste has become a key challenge in society for economic, social and environmental reasons. QUT has a long history of converting waste to more valuable products in agriculture industries and is now also focusing on livestock, fashion and domestic waste. We bring together transdisciplinary teams of researchers to solve the complex challenges associated with accessing, sorting, processing and transforming wastes with teams including scientists, engineers, designers, business people and lawyers.

Synthesis of robust desalination membranes with high water permeability

The aim of this project is to use in-situ polymerisation to create an interpenetrated network of hydrophilic polymer within the less hydrophilic support layer of desalination membranes. Increased hydrophilicity is expected to increase water flux and hence desalination efficiency without a negative effect on water permeability.

Stochastic patterns of tissue inclusions

Biological tissue growth involves the secretion of new tissue (extracellular matrix, collagen fibers) by cells. This secretion incorporates scattered inclusions such as proteins and minerals into the new tissue. During bone tissue growth, some of the tissue-secreting cells themselves become incorporated into the new tissue. The distribution of these tissue-embedded cells is believed to influence subsequent tissue growth processes.

Epitaxial growth of 2D heterostructures on SiC for electronics and gas sensing

Graphene has attracted a great deal of interest due to its remarkable electronic, optical and mechanical properties, however the absence of a bandgap limits its use in many applications. Future applications in nanoelectronics and gas sensing will depend critically on the development of novel approaches to introduce a bandgap while preserving carrier mobility, for example by creating heterostructures of graphene with other two dimensional (2D) materials with complementary properties.This project will explore the heteroepitaxial growth of new 2D materials to …

Precursors of atmospheric aerosols in the Southern Ocean and Antarctica

Aerosols are tiny liquid or solid particles suspended in air. They have a significant role in the radiative balance through their direct interaction with incoming solar radiation (scattering and absorption) , and indirectly through their interactions with cloud (they act as seeds on which water can condense to form clouds). Indirect effect is a much more complex problem, and involves the role of aerosols in the cloud formation and the modification of their properties such as changes to cloud reflectivity, …

A real-time system for monitoring oxidative potential of PM

Particulate matter (PM), a major component of outdoor and indoor air pollution was recently classified by World Health Organization as carcinogenic to humans. The underlying toxicological mechanisms by which particles induce adverse health effects are still not entirely known. Numerous toxicological studies have demonstrated that particles have the ability to generate free radicals and related reactive oxygen species (ROS), which are able to induce oxidative stress at the sites of deposition (i.e. lungs).A fluorescence-based profluorescent nitroxide (PFN) molecular probe synthesized …

Treatment of mine wastewaters

Mining processes create wastewater that is typically unsuitable for release into the environment without some form of treatment. Treatments will vary depending on the composition of the wastewater and where the water is to be reused.

Surgery with rockets

Self-propelled nano/microscale rockets have been developed that consume locally supplied chemical fuels to generate thrust, analogous to how large rocket engines ignite onboard propellants. Such rockets offer tremendous advantages as nano/microdevices. They can be designed for low or high velocities (up to 1000 body lengths/sec), can tow large loads, have remarkable design flexibility, and allow surface functionalisation with nanomaterials and biomolecules.1,2Unlike their macroscale counterparts, these rockets have the advantage of harvesting their chemical fuel directly from their surrounding environment. In …

Understanding and exploiting the phenomenal properties of collagen

Collagen is the most abundant protein in the human body and, as one of its principal building blocks, plays a dominant role in the function of many tissues. As such, the structure-property-function relationships in collagen are central to understanding health and disease, and developing materials-based strategies for regenerative medicine. A better understanding of these relationships further provides a biomimetic target for high-performance, multifunctional fibre-based materials in applications outside of biomedicine. The defining feature of collagen is an elegant structural motif …

Spider silk: structure, mechanics and processing

Spider silks possess a range of qualities that are rarely found simultaneously in one material, and it is no surprise that an enormous effort has been made to replicate or learn from them.1,2 Toughness, extensibility and strength are only a few of the desirable traits that make spider silk of such interest. Silk is biodegradable and, unlike synthetic high-performance fibres such as Kevlar, it is extremely lightweight.3,4 A further advantage lies in its processing conditions and requirements. Whereas production of …
