Title of Speech: Soft Plasmene Nanosheets: From Design to Applications 

Abstract: My nanobionics research lab concentrate on the design of soft/hard nanohybrids based on metallic nanoparticles capped by soft ligands including DNA, polymer and alkyl molecules. We have successfully applied such soft particles to four major directions: (1) assembling soft plasmonic nanoparticle superlattice sheets (soft plasmene sheets) 1, 2, 3, 4, 5, 6; (2) fabricating electronic skins (e-skins) for wearable sensors 7, 8, 9; (3) fabricating soft energy devices 8; (4) DNA aptamer-targeted and light-controlled drug delivery.
In this talk, I will focus on the discussion of the first project for producing soft, elastic, two-dimensional plasmonic nanoparticle superlattice sheets (soft plasmene sheets) by self-assembly of polystyrene-capped metal nanoparticles. The soft nanosheets could be folded into 1D nanoribbons and 3D origami, and they can serve as a new-class SERS substrate which is soft, elastic and surface-attachable. This enabled the direct chemical identification on topologically complex surfaces such as banknotes and coins, and application as new-generation of anti-counterfeit security labels.

Title of Speech: Progress in rolling technology and development of novel composite materials 

Abstract: Sticking and ridging which usually occur on strip surfaces of Ferritic Stainless Steel (FSS) have been significantly reduced after optimisation of rolling parameters, leading to improved surface quality of hot rolled FSS products. An innovative water-based nanolubricant used for hot steel rolling, which is environmentally-friendly and recyclable, has been developed to decrease rolling force, surface roughness and oxide scale thickness of rolled steel, resulting in low energy consumption, improved surface quality and high yield. All the advanced rolling technologies contribute to economic benefits to a large extent in the steel industry. In addition, aluminium matrix composites (AMCs) reinforced with the core-shell nanoparticles were fabricated following a powder metallurgy technique. The well dispersed SiC-GNSs nanoparticles restrain the grain growth during sintering and nanostructured composite is achieved. The lowest wear rate and coefficient of friction of AMCs were obtained in sliding wear tests, which were 98.0% and 35.9% respectively lower than that of the reference sample reinforced with solely SiC nanoparticles.

Title of Speech: Future Fibres Research and Development 

Abstract: Future fibres are fibres for the future. These materials are functional, fit-for-purpose, and sustainable.
This presentation will give a snapshot of recent fibre materials research and development, with a focus on collaborative research activities under the ARC Research Hub for Future Fibres. The talk will also discuss how future fibres not only impact on our daily life but also the mission to colonising the Mars.
There have been major developments in fibre materials research and translation in recent years, at Deakin University’s Waurn Ponds campus in Geelong. These developments include the $103 million infrastructure development work supported by both federal government under the EIF program and the Victoria State government, and the $13 million Future Fibres Industrial Transformation Research Hub supported by the Australian Research Council and local industry partners. A number of highly innovative companies have also established R&D and manufacturing bases in Geelong, which are transforming the local manufacturing sector.

Title of Speech: Design and Engineering of Sustainable Packaging Materials with Cellulose Nanofibres 

Abstract: Developing advanced barrier materials with sustainable materials is a challenging task. Currently, the synthetic polymers in food, medical and pharmaceutical packaging are neither renewable nor biodegradable, and are accumulating in the environment, damaging the eco-system. While packaging from paper-polymer laminates is partially renewable, it is difficult to recycle. Nanocellulose is a renewable, biodegradable material produced via mechanical and chemical processing to break down cellulose fibres into nanofibres. Nanocellulose films are recyclable, translucent, strong, have reasonable barrier properties and are under active investigation as a replacement for conventional petroleum derived plastics in packaging.
In this presentation, the properties and performance requirements of conventional packaging will be reviewed and compared to nanocellulose films. While nanocellulose films have excellent gas barrier performance, the resistance to liquid water and water vapour is poorer than fossil fuel derived polymers such as LDPE.
Material design strategies that we have investigated to improve the performance include:
• Micro-nano dual scale roughness coatings to provide a superhydrophobic surface.
• Reducing nanofibre diameter by increasing energy input in fibre separation, to decrease the size of the pores in the film.
• Chemical pre-treatment to reduce fibre diameter by oxidising the cellulose.
• Producing nanoparticle-nanocellulose composites to increase the film tortuosity
• Laminating the nanocellulose sheet with a bio-based adhesive to a base sheet.
In this presentation, the effectiveness and properties achievable using each of these strategies will be reviewed. The results show that a synergistic approach using multiple strategies is required in order to meet the performance requirements. Finally a conceptual design for a nanocellulose packaging material will be presented.
