Chemical characterisation of biomass burning smoke particles using Electrospray-Orbitrap mass spectrometry

Australian bushfires and prescribed biomass burning (BB) have a significant impact on both human health as well as global and regional climate.While emissions from traditional sources, such as vehicles and power plants are expected to decline due to more stringent regulations, air pollution from BB smoke is expected to continue growing.The impact of BB smoke particulate matter on human health will depend on their chemical and physical properties. However, that information for smoke from Australian ecosystems is very limited.The aim …

Online aerosol chemical characterisation using Particle Into Liquid Sampler coupled to Electrospray Ionisation Orbitrap Mass Spectrometry

Atmospheric aerosols are important as they have impact on earth’s climate and human health.Organic components represent a significant fraction of atmospheric aerosols. They can be directly emitted in the atmosphere or formed in the atmosphere by oxidation of gaseous precursors.Real-time characterisation of organic aerosol is required to understand their sources, formation and ageing (change) in the atmosphere.There are several mass spectrometry techniques currently used for real-time characterisation of organic aerosols. However, the techniques use hard ionisation, resulting in molecular fragmentation, …

Laboratory simulation of Secondary Organic Aerosol (SOA) formation

This project aims to investigate the interaction of anthropogenic (human-made) emissions and biogenic emissions from plants and trees and subsequent secondary organic aerosol (SOA) production in urban environments. This is relevant as SOA is part of particulate matter (PM), which is associated with smog events in cities, affects the climate and has negative impacts on human health.SOA is formed in the atmosphere by complex reactions of volatile organic compounds (VOCs) of anthropogenic or biogenic origin with atmospheric oxidants (OH radicals, …

Super metal organic framework-mineral composite material for hydrogen energy storage

Metal-organic frameworks (MOFs) are an emerging class of crystalline materials that hold huge promise for significant applications such as adsorption, separation, catalysis and drug delivery. Attributed to their exceptional porosity and surface area, the adsorptive performance of MOF materials has high potential for solving challenging issues such as hydrogen storage, greenhouse gas capture and water vapour harvest in arid regions.However, the practical application of many MOF materials encounters challenges from poor chemical stabilities, low yields and expensive manufacturing costs. With …

Research and development of novel building materials using Australian natural minerals

This project will explore the potentials of local natural minerals and waste products for developing next-generation, high-quality precast panels that impose a high cost environmental footprint.Our research will:advance fundamental knowledge of natural mineralsreduce building industry dependence on lower-quality imported productsexpedite local manufacturing of energy efficient solutions for building facades, roofs and wall systems.Use of precast panels speeds up construction, reduces on site defects, construction times, scaffolding and site labour costs. These advantages contribute to increased productivity in the building industry. …

Precursors of atmospheric aerosols in the Southern Ocean and Antarctica

Atmospheric 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, cloud …

Investigating the potential for sea spray aerosol to mitigate coral bleaching

Mass coral bleaching events over the past decade have heightened the need for research into techniques to enhance survival of the Great Barrier Reef.Applying sea spray aerosol directly over coral reefs during periods of increased bleaching stress could mitigate bleaching by both locally reducing sea surface temperatures and by reducing incoming incident solar radiation. These effects are referred to as solar radiation management and can be broken up into the direct scattering of incoming solar radiation and via the interaction …

Novel heterogeneous Fenton catalysts for wastewater treatment and reuse

The shortage of freshwater supply in many areas in Australia makes reusing wastewater highly necessary, and proper treatment of wastewater at reasonable costs is critical for the industrial sustainability.For example, the food and beverage processing industry is Australia’s largest manufacturing industry in terms of both financial contribution and employment. This industry consumes massive amounts of freshwater and produces a large quantity of wastewater containing various organic contaminants.Currently, a range of pre-treatment techniques including dissolved air flotation, bioreactor and conventional Fenton …
