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: Development of heatpipe plate technologies for high performance cooling applications
Abstract: Cooling of PV cells is important to maintain optimum conversion efficiency and has attracted significant attention recently to develop various techniques for such an application [1,2]. This presentation will report the development of a novel heatpipe plate for application in cooling PV cells. The heatpipe plate consists of a metal casing with microchannels and nano-coated porous materials as wicking medium. Several heatpipe plates with different internal designs and conditions are investigated to determine the effect of different design parameters. Results on the wicking behaviour of the porous materials and the thermal performance of the cooling device in controlled conditions will be presented. It is found that the heatpipe plates integrating both microgrooves and metal foams with nano-coatings can achieve highly efficient heat removal and mass transfer. The heat removal is also dictated by the ability of heat removal from the condensation section. By thermal control at the condensation section, the maximum heat removal ability is significantly improved. The experiment indicates that 60% of heat input can be effectively removed by the integrated device. The device has potential in many high flux cooling applications.

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: Smart Materials for Chipless RFID Sensors: Revolution in Identification and Sensing in the New Millennium
Abstract: In the era of information communication technology (ICT), Radio Frequency IDentification (RFID) has been going through tremendous development. RFID market will surpassed $19 bn by 2019. RFID technology has the potential of replacing barcodes due to its large information carrying capacity, flexibility in operations and versatilities in applications. However, the penetration of RFID technology is hindered due to its high price tag. Many projects had been stalled only due to the cost of the tag. The application specific integrated circuits (ASICs) in RFID tags are the most expensive item. Fully printable chipless tags will provide competitive advantages over barcodes. If chipless RFID can be made less than a cent, then chipless RFID market will open up many potential market opportunity in retails, constructions, logistics and supply chain managements in manufacturing sectors.
With unique features of identification, tracing and tracking capabilities, RFID also gives value added services incorporating various sensors for real-time monitoring of assets, public installations and people from various backgrounds. Chipless RFID sensors for temperature, relative humidity, pH, impact and presence of noxious gas monitoring have opened new prospects. The market will grow to tens of billions. This research has opened up new research and development opportunities of functional materials applied to wireless sensing of assets, public installations. Such sensors are the backbone of internet of things (IoT).
Since the chipless tag has no intelligence, the signal processing is done only in the reader. Therefore, a full new set of requirements and challenges is needed to be incorporated and addressed, respectively, in the chipless RFID tag reader. This seminar addresses the development made in new smart materials for new chipless RFID tags and sensors, reader architecture and signal processing techniques at Monash University.

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.
