Formation of Single Walled Carbon Nanotubes Via the Interaction of Graphene Nanoribbons: ab initio Density Functional Calculations

Du A.J., Smith S.C., Lu G.Q., University of Queensland, AU

Recently, single graphite layers, referred to as Graphene nanoribbons (GNR) have been prepared experimentally by using conventional methods, such as cutting mechanically exfoloiated graphenes or by patterning epitaxially grown graphenes [1-2]. On the other hand, [...]

Layer by Layer Fabrication of an Amperometric Nanocomposite Biosensor for Sulfite

Adeloju S.B., Ohanessian A., Water and Sensor Research Group, AU

This paper will present the results of a layer by layer strategy that we have developed for the fabrication of a polypyrrole nanocomposite amperometric biosensor for sulfite. The use of this strategy to fabricate bilayer [...]

Block Copolymer Directed Nanocomposites for Fuel Cell Applications

Dermis T., Mayavan S., Dutta N.K., Choudhury N.R., Holdcroft S., University of South Australia, AU

Block copolymers [1,2] and ionomers comprising fluoro/non-fluoro segments have significant potential applications in the field of fuel cell. However, they are very difficult to synthesize; because fluoro monomers are not amenable to living ionic polymerization [...]

Transforming nano-science to nano-technology: Manipulating the size, shape, surface morphology, agglomeration, phases and defects of silver nano-particles under continuous flow conditions

Iyer S., Raston C.L., Saunders M., The University of Western Australia, AU

Spinning disc processing (SDP) is an instantaneously scalable, continuous flow and high throughput flash nano-fabrication technology which embraces green chemistry metrics. It has been used to prepare silver nano-particles with remarkable control in size (5 [...]

Synthesis and characterisation of flame-sprayed superparamagnetic bare and silica-coated maghemite nanoparticles

Teoh W.Y., Li D., Selomulya C., Woodward R., Amal R., Monash University, AU

Magnetic nanoparticles are a much sought-after entity with direct applications in bioseparation, magnetic resonance imaging (MRI), drug delivery and cancer therapy. gamma-Fe2O3 and SiO2/ gamma-Fe2O3 nanoparticles of different sizes (dBET = 5-50 nm) were synthesised [...]

Lattice Engineered Nanoparticles

Casey P., Rossouw C.J., Murphy A.B., Bell C., Commonwealth Scientific and Research Organisation, AU

Nano-particulate oxides such as ZnO and TiO2 are receiving much attention as functional nanoparticles predominantly due to their increased efficiency in absorbing UV at small particle sizes. However, whilst protection against UV may be maintained [...]

Stable Isotope Tracing – a way forward for Nanotechnology?

Gulson B., Wong H., McCall M., Danon S., Greenoak G., Trotter J., Casey P., Stauber J., Commonwealth Scientifc and Industrial Research Organisation, AU

Numerous publications and reports have expressed health and safety concerns about the production and use of nanoparticles, especially in areas of exposure monitoring, personal use, and environmental fate and transport. We suggest that stable isotopic [...]

An integrated, industry-linked approach to developing a nanotechnology curriculum for secondary students in Australia

Alford K.J.S., Calati F., Binks P.N., Bridge 8 Pty Ltd, AU

Nanotechnology is a discipline that will require scientists to draw upon many disciplines in order to develop it to its full potential. It will also require significant public engagement to debate and decide on nanotechnology’s [...]

Molecular Simulation and Theory for Nanosystems

Sadus R.J., Swinburne University of Technology, AU

A knowledge of self-assembling molecules such as DNA and dendritic systems can provide beneficial insights for the development of tailor-made nano-scale devices. In this context, molecular simulation and theory have an important role in both [...]
