Development of a metrological scanning probe microscope as a primary standard for nanoscale dimensional measurement

Babic B., Freund C., Gray M.B., Herrmann J., Hsu M.T.L., Lawn M., McRae T.G., National Measurement Institute Australia, AU

The capability for accurate dimensional measurement at the nanoscale, traceable to the SI meter, is fundamental for the development and effective support of nanoscience and nanotechnology. At the National Measurement Institute Australia (NMIA), the primary [...]

Sulfated chitosan (SCS)/polysulfone (PS) composite nanofiltration membrane surface cross-linked by Epichlorohydrin

Miao J., Xie Z.H., Chen G.H., Edith Cowan University, AU

A series of composite nanofiltration membranes were prepared via a method of coating and cross-linking from sulfated chitosan (SCS) as the material of the active layer, Polysulfone (PS) UF membrane as the base membrane, and [...]

The Effect of Lamination on Printed Silver Tracks for Plastic Circuits

Neeli M.R., Thiel D.V., Griffith University, AU

To combat the global e-waste crisis, there is an urgent need to develop a technology where environmental pollution from electronics, their manufacturing and product end of life is minimized through recycling and re-use. Circuits in [...]

Tailoring Pt-Alloy Cluster Nanoparticles for Enhanced Electrocatalytic Activity

Balu R., Roy Choudhury N.K. Dutta N., Elvin C.M., Hill A.J., University of South Australia, AU

Polymer electrolyte membrane fuel cell, PEMFC is an electrochemical energy conversion device that has the potential to be an alternative to internal combustion engines. However, the complexity and slow oxygen reduction reaction (ORR) kinetics on [...]

Self Assembled Nanostructures of Triblock Co-polymer and Plasmid DNA for Gene Delivery

Daima H.K., Shankar P.R. Selvakannan S., Bhargava S.K., Bansal V., RMIT University, AU

In present work, we have used tri-block copolymer (PEO-PPO-PEO) as a non-viral vector to deliver plasmid DNA (pDNA). Green fluorescence protein (GFP) plasmid DNA was used as a model plasmid DNA. Addition of pDNA to [...]

Sequential Surface Functionalization by Polyoxometalates and Lysine Renders Non-toxic Gold Nanoparticles Strong Antibacterial Agents

Daima H.K., Selvakannan P.R., Bhargava S.K., Bansal V., RMIT University, AU

Gold nanoparticles (AuNPs)are considered as biocompatible and important component for biomedical applications. In current study, AuNPs were synthesised using tyrosine amino acid mediated reduction of gold ions. These nanoparticles were functionalised with two polyoxometalates (POMs) [...]

Nanotribology and Lubrication at Nanoscale: Molecular Dynamics Simulation Studies

Jabbarzadeh A., The University of Sydney, AU

Increasing technological advances to make devices and processes at the nanoscale, have made it necessary to effectively minimize the friction and adhesion of moving mechanical assemblies, such as those in micro- or nano-electromechanical (MEMS/NEMS) devices. [...]
