The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

The systematic development of fundamentally important group 15 compounds: their applications to innovative industrial and environmental processes. The strong coordinating ability of organo-phosphorus/arsonic acids will be harnessed to support a series of metallic clusters that will be exploited for their use as magnetic materials in gas storage and as catalysts. The novel acids will be investigated for use as water soluble purification agents for, for example, mercury, uranium and lead.
Understanding wastewater treatment technologies for alternative water use: transformation of inorganic and organic nitrogen. This project will identify sustainable treatment processes for nitrogen and pathogen removal in rural wastewater treatment systems. The outcomes will provide water utilities and regulators with practical recommendations for minimising chemical and microbial risks of alternative uses of treated wastewater, and improve rural long-term water security.

Summary
Biofilms in two-dimensional turbulent flows:effects on Lagrangian transport. This project aims to investigate how surface biofilms affect flows at the ocean surface. Great stretches of the ocean surface are covered by an organic microlayer called biofilm. Flows at the ocean surface are a crucial part of climate machinery, and biofilms have profound, largely unexplored effects on these flows. There is no fundamental understanding of how biofilms affect fluid motion. This project aims to use labor ....Biofilms in two-dimensional turbulent flows:effects on Lagrangian transport. This project aims to investigate how surface biofilms affect flows at the ocean surface. Great stretches of the ocean surface are covered by an organic microlayer called biofilm. Flows at the ocean surface are a crucial part of climate machinery, and biofilms have profound, largely unexplored effects on these flows. There is no fundamental understanding of how biofilms affect fluid motion. This project aims to use laboratory models and new measurement techniques to study and quantify the impact of biofilms on turbulent transport. Understanding these effects is important in a time of climate change and this knowledge may also help address environmental issues related to spreading of pollutants and flow control at the ocean surface.Read moreRead less
Remote sensing estimation of greenhouse gas emissions from floodplains in the wet-dry tropics. This project provides regional-scale estimates of greenhouse gas emissions from major floodplains in the wet-dry tropics. These estimates are required for future national carbon accounting, and are critical knowledge gaps for current global climate models.
Porous Nanosheets. This research aims to develop novel efficient absorbent materials from porous boron (carbon) nitride (B(C)N) nanosheets, which are new two-dimensional (2D) nanomaterials consisting of a few atomic layers. The porous B(C)N nanosheets have a large surface area and a strong selective adsorption property. In addition, they can be regenerated and re-used for many times due to high thermal stability. This project aims to synthesise these nanosheets with controlled nanoporous structu ....Porous Nanosheets. This research aims to develop novel efficient absorbent materials from porous boron (carbon) nitride (B(C)N) nanosheets, which are new two-dimensional (2D) nanomaterials consisting of a few atomic layers. The porous B(C)N nanosheets have a large surface area and a strong selective adsorption property. In addition, they can be regenerated and re-used for many times due to high thermal stability. This project aims to synthesise these nanosheets with controlled nanoporous structures. Applications for removing pollutants from water and air will be evaluated. The outcomes are expected to advance our knowledge in 2D nanomaterials, create new technologies for cleaning-up of oil spillage and contaminated water, and provide benefits for environmental protection.Read moreRead less
A study of some physical properties of concentrated salt solutions. The foam we see on the sea shore is caused by the effects of salt in seawater and is one example of the unusual properties of water. These effects can be applied to understand and improve several important processes, such as, boiling, desalination and the precipitation of fine particles from concentrated salt solutions.
Creating custom microenvironments for anion complexation in water. This proposal will exploit a new strategy in the design of anion receptors that function in water by employing the microenvironment formed in aggregates of these molecules. The outcome of the project will be a series of new materials designed to selective bind particular anions, a deeper understanding of how to design novel anion-selective materials and control the assembly of these systems. The materials will have potential us ....Creating custom microenvironments for anion complexation in water.

The outcome of the project will be a series of new materials designed to selective bind particular anions, a deeper understanding of how to design novel anion-selective materials and control the assembly of these systems. The materials will have potential uses in processes where the removal of particular anions is required. Potential applications include desalination, radioactive waste remediation, corrosion-resistant coatings and removal of anions during dialysis processes.Read moreRead less
Water in the deep Earth. Water has profound influence on many deep Earth processes ranging from melting to plate movements. Water in deep Earth is replenished by subduction. A significant part of water can be stored in nominally anhydrous minerals, such as olivine, pyroxene and garnet that result from the breakdown of hydrous phases within the subducted lithosphere. The project proposes a combined experimental and analytical project to determine how much water is transported to the deeper mantle ....Water in the deep Earth.

The project proposes a combined experimental and analytical project to determine how much water is transported to the deeper mantle in these minerals. This project aims to determine the incorporation mechanisms of water into these key minerals and to establish an Australian facility for water determination in minerals that has the sensitivity needed for studying deep Earth materials.Read moreRead less
Bacteriophages for foam control in wastewater processing. This project will develop new strategies to reduce troublesome foaming at sewerage treatment plants in Australia. It will enable water authorities to prevent foaming events, increase wastewater treatment safety and efficiency, decrease environmental and human health impacts and aid recycling of urban and industrial wastewaters.
Rapid amperometric measurement of chemical oxygen demand in polluted water based on electrochemical and photocatalytic properties of nanoparticulates. The project will enhance a newly developed technology for measuring aggregate organic pollution in wastewater. The conventional wet chemistry method is disadvantaged by being slow (2 hr) and requiring toxic heavy metal (mercury, chromium) and hazardous reagents. Aqua Diagnostic's method, by contrast, is rapid (5-10 minutes) and uses only safe ch ....Rapid amperometric measurement of chemical oxygen demand in polluted water based on electrochemical and photocatalytic properties of nanoparticulates. The project will enhance a newly developed technology for measuring aggregate organic pollution in wastewater. The conventional wet chemistry method is disadvantaged by being slow (2 hr) and requiring toxic heavy metal (mercury, chromium) and hazardous reagents. Aqua Diagnostic's method, by contrast, is rapid (5-10 minutes) and uses only safe chemical reagents. It will be further improved to facilitate unprecedented near-real-time (less than 1 minute) online pollution monitoring and greater analytical robustness. The project will directly benefit the wastewater management community, enrich Australian industry's expertise in nanotechnology applications and grow high-tech exports as this innovative technology continues to penetrate international markets.Read moreRead less
