Hofmeister at work. Implementation of a paradigm shift in physical chemistry. Standard tools of measurement in environmental, industrial, colloid, nano and biosciences rest on classical theories which have been shown to be badly flawed. The faults have been remedied to give a new, predictive and usable foundation that amounts to a paradigm shift of immediate importance to many applications.
Characterisation of nanobubbles. Surprisingly, nano-sized bubbles have recently been found to exist in aqueous solutions. Classical theory tells us they should rapidly dissolve, yet they are stable for several days, a phenomenon which has only recently been explained. Despite this, nanobubbles are already used in cleaning processes and appear to have significant health benefits. They are being investigated in treatments for asthma and neurodegenerative diseases. In collaboration with a pharmaceu ....Characterisation of nanobubbles. Surprisingly, nano-sized bubbles have recently been found to exist in aqueous solutions. Classical theory tells us they should rapidly dissolve, yet they are stable for several days, a phenomenon which has only recently been explained. Despite this, nanobubbles are already used in cleaning processes and appear to have significant health benefits. They are being investigated in treatments for asthma and neurodegenerative diseases. In collaboration with a pharmaceutical company, the best means to produce and characterise nanobubbles will be investigated, as well as the conditions governing their stability. The project also aims to determine how the nanobubbles interact with surfaces in order to better control their properties and achieve a better understanding of these bubbles.Read moreRead less
Using light to move molecules-a novel approach to exploring intermolecular forces. It is in the last few nanometres above a surface that many real-world effects originate. Using a fine stylus and the momentum from a laser beam, the project will nano-mechanically perturb molecules to reveal forces on a sub-molecular scale. Gaining control at this scale is central to developing an understanding of many natural and industrial processes.
Surface forces between novel surfaces. Friction, adhesion, the self assembly of molecules essential to life and the flow properties of slurries is explained via an understanding of surface forces. These very short-range forces are often studied using ideal surfaces of very low roughness. As only a few surfaces are available with these ideal characteristics this has greatly limited the choice of materials that could previously be employed in surface force investigations. This project will use ato ....Surface forces between novel surfaces. Friction, adhesion, the self assembly of molecules essential to life and the flow properties of slurries is explained via an understanding of surface forces. These very short-range forces are often studied using ideal surfaces of very low roughness. As only a few surfaces are available with these ideal characteristics this has greatly limited the choice of materials that could previously be employed in surface force investigations. This project will use atomic layer deposition to produce thin films of novel materials that are extremely smooth and highly suitable for such investigations. Thereby, the understanding of surface forces, adhesion and adsorption phenomenon will be expanded to a wide range of new materials. Read moreRead less

Surface and Colloid Characterisation Facility. Surface and colloid characterisation facility: Surface science lies at the heart of biointerface and colloid science. This facility will enable particle size, shape, distribution, surface area and charge to be measured as well as the amount of material adsorbed to interfaces, the configuration of that material and the response of the surface to stimuli such as changing pH or salinity.

This facility will enable particle size, shape, distribution, surface area and charge to be measured as well as the amount of material adsorbed to interfaces, the configuration of that material and the response of the surface to stimuli such as changing pH or salinity. All these parameters influence the properties of these important systems. As such this facility will underpin the research of a number of groups across three institutions over the next decade and promote collaboration between scientists with a range of complementary expertise in fields where surface science is important from biology to ionic liquids.Read moreRead less
Unravelling the dominant drivers of ion specificity. This project aims to understand what governs the sensitivity of many technological and biological processes to the precise nature of the salt present in solution. The term ‘ion-specific’ encompasses all the circumstances in which the influence of a salt in solution depends on the precise chemical nature of the salt, not just the electrical charge on the ions that form the salt. As such, ion-specific effects abound and have important consequenc ....Unravelling the dominant drivers of ion specificity. This project aims to understand what governs the sensitivity of many technological and biological processes to the precise nature of the salt present in solution. The term ‘ion-specific’ encompasses all the circumstances in which the influence of a salt in solution depends on the precise chemical nature of the salt, not just the electrical charge on the ions that form the salt. As such, ion-specific effects abound and have important consequences in most situations involving solutions, including cellular functions and battery technology. This project will enable us to understand and control the influence of specific ions, building on our recently described fundamental ion-specific series with colloid science experiments and quantum simulations. This project should overcome current challenges in predicting ion-specific effects leading to progress in a wide variety of applications of colloid and interface science, from sensor interfaces to self-assembly.Read moreRead less
Forensic platform technologies for roadside and workplace testing based on nanostructured silicon chips. Roadside drug testing has recently been incorporated into government legislation throughout Australia and abroad. The objective of this project is to develop advanced analysis technologies for implementing effective roadside and workplace testing. The availability of these technologies will increase the safety of Australian drivers and workers.

This project aims to remove carbon dioxide from the atmosphere as part of a reaction to produce a carbon-neutral solar fuel. People are currently still over reliant on fossil fuels for energy production, which leads to increased greenhouse gases and their detrimental climate effect. This project will develop novel wireless sustainable nano-reactors, which can be scaled to a system working in an ambient environment for high-yield production. The expected outcomes are to synthesise nano-flowers composed of 2D functional nano-leaves, which will be fabricated into a flexible large-area carbon dioxide-to-solar fuel system. This project will also expand knowledge in heterojunctions, surface chemistry and nano-manufacturing of 2D materials. The technology to be developed will only rely on natural solar, atmospheric, and earth-abundant eco-friendly resources, and intends to promote Australia as a key regional solar fuels production and export nation.Read moreRead less
