Modifications to permeable pavement structure to achieve improved heavy metal attenuation in stormwater runoff

Kuruppu U., Rahman A., Sathasivan A., Western Sydney University, AU

This paper reports a study conducted to investigate the influence of rainfall intensity and subbase materials on attenuation of heavy metals in stormwater runoff through permeable pavements. The porous structure of permeable pavements facilitates the [...]

Effect of polymer ratio on nZVI loading onto electrospun nanofiber mat for mitigating groundwater contaminants

Ren J., Tijing L.D., Shon H.K., University of Technology Sydney, AU

Nanoscale zero-valent iron (nZVI) has been widely used for the reduction of halogenated organics and heavy metals in the groundwater. However, individual nZVI particles are mobile and prone to aggregate, thereby reducing the reaction sites [...]

Stretchable Gas and UV Sensors towards Wearable Electronics

Gutruf P., Walia S., Zeller E., Nili H., Sriram S., Bhaskaran M., RMIT University, AU

Electronics and sensors pervade all aspects of life, needing solutions to make them less obtrusive, which is where fully transparent electronics come into play. Our research focus has been to realise stretchable electronic devices with [...]

Carbon Nanotube Silicon Heterojunction Solar Cells

Yu L., Tune D., Shapter J., Flinders University, AU

Due to the high cost of silicon photovoltaics there is currently great interest in finding alternative semiconductor materials for light harvesting devices. Single walled carbon nanotubes (SWCNTs) are an allotrope of carbon having unique electrical [...]

Guidelines for choosing an appropriate turbulence model when simulating blood flows in cardiovascular devices

Simpson B.A.F., Tansley G.D., Griffith University, AU

A systematic and detailed comparative study of computational results with validating experimental data has helped define the turbulence models that are most appropriate for predicting the velocity fields and shear forces in blood flows. The [...]

230 fold fluorescence enhancement by 3D Rhodamine B coated polystyrene photonic crystals

Eftekhari E., Li Q., Li X., Cole I.S., Li Q., Li X., Griffith University, AU

We report a 230-fold fluorescence enhancement with fluorescent polystyrene based three-dimensional (3D) colloidal photonic crystals (F-CPhCs) that can be readily fabricated over large areas. A simple and reproducible method was developed to synthesise novel fluorescent [...]

Efficient drug delivery for cancer treatment using amine-functional SiO2-LDH nanocomposites

Li L., Liu J., Gu W.Y., Gu Z., Gu W.Y., Gu Z., Liu J., Xu Z.P., Australian Institute for Bioengineering and Nanotechnology, AU

Target-specific delivery and sustained release of anticancer agents and siRNA has attracted considerable research interest in cancer chemotherapy. Recently, we have developed layered double hydroxide (LDH) vector to efficiently deliver drug and siRNA into the [...]

Pelletized silica and amine composites for CO2 capture via adsorption

Knowles G.P., Vogt C., Chaffee A.L., Cooperative Research Center for Greenhouse Gas Technologies, AU

Solid amine sorbent powders are of broad interest to facilitate CO2 capture towards reducing atmospheric greenhouse gas. It is recognized, however, that pelletized rather powdered adsorbents are required for industrial adsorption separation processes. “Molecular basket” [...]

Layered Quantum Dot based Chromogenic Membranes for pH Sensing

Cole I.S., Trinchi A., Hardin S.G., CSIRO, AU

The development of inexpensive, flexible, robust pH sensors with an optical mode of operation remains a key challenge. Monitoring pH is a critical capability, and in most lab applications is carried out using the electrochemical [...]
