Structural conformations of ATP/Mg:ATP and Mg2+ coordinating dynamics in motor proteins

Bojovschi A., Liu M.S., Sadus R.J., Swinburne University of Technology, AU

ATP-powered motor proteins are driven by ATP hydrolysis. The conformational dynamics of ATP is functionally crucial for the steady operation of motor proteins. In this paper, we present conformational diversity of the ATP/Mg:ATP and coordinating [...]

Self Healing Hybrid Coating for Aggressive Environment

Vashisth C., Potrekar R., Roy Choudhury N., Dutta N.K., University of South Australia, AU

Self healing is a desirable property of a coating on metallic substrate to help arrest the development of micro-cracks and the propagation of corrosive species to the interfacial layer and eventually to the substrate. While [...]

Dielectric performance of Polymer Nanocomposites Synthesized by Atmospheric-pressure Plasma-treated Silica Nanoparticles

Yan W., University of New South Wales, AU

The incorporation of nanoparticles can effectively enhance the dielectric performance of polymers. However, the organic-inorganic incompatibility prevents the nanocomposites from obtaining the desired properties. To overcome this issue, coupling agents have been used to coat [...]

Highly Luminescent Quantum Dots: New Tools for Biological Applications

Mirnajafizadeh F., Wang F., Reece P., Stride J.A., University of New South Wales, AU

Quantum dots (QDs) are a special class of nano particles with unique optical properties. They are very good candidate materials for medical and biological applications. In order to apply QDs to biological systems, they should [...]

Tuning Wettability of Electrospun Three-dimensional Scaffolds through Morphology Control

Ahmed F., Choudhury N.R., Dutta N.K., University of South Australia, AU

Surface wettability plays an important role in determining implant’s fate due to direct influence of protein/biomolecule adsorption that governs cell adhesion. The importance of the physical parameters, such as, overall porosity, pore directionality, difference between [...]

Rowe T., Ceramic Fuel Cells Limited, AU

Ceramic Fuel Cells has developing an innovative solid oxide fuel cell technology that offers the world’s highest level of electrical conversion efficiency. CFCL’s fuel cells provide highly efficient and low-emission electricity from widely available natural [...]

RAFT Polymerisation for delivery of bioactives

Chiefari J., CSIRO, AU

The RAFT (Reverse Addition-Fragmentation chain Transfer) process is a ground breaking technology that offers unprecedented control over the composition, functionality and architecture of polymers. The versatility of the RAFT technology provides enormous potential for designing [...]

Biomimetic High Filler Content Composites using Bisphenol-A Ethoxy Diacrylate

Daud N., Shanks R.A., RMIT University, AU

Materials were prepared similar to nacre with its layered structure of high filler content. Nacre is based upon about 95 %·w/w calcium carbonate as a composite with a layered block structure. Nacre has high modulus, [...]

A Novel Silicon-based Wideband Nano Switch for RF Applications

Yang Y.X., Ramer R., University of New South Wales (UNSW), AU

This paper presents, for the first time, a silicon-based wideband RF nano switch with simulation fabrication measurement and analysis. Port-to-port simulation results of the RF nano switch indicate that the designed switch has a potential [...]

Nanoscale Force Induced Size-selective Separation and Self-assembly of Metal Nanoparticles

Zheng Y., Monash University, AU

A simple and versatile nanoscale force induced precipitation approach for the separation of gold nanoparticles (AuNPs) was developed. The AuNPs show sharp size-dependent colloidal stability thresholds as a function of salt concentration. Upon separation, the [...]
