Pelletized silica and polyethyleneimine composites for CO2 capture via adsorption

Knowles G.P., Chaffee A.L., Monash University, AU

Amine adsorbent powders are of broad interest to facilitate CO2 capture towards reducing atmospheric greenhouse gas. It is recognized, however, that industrial adsorption processes require pelletized rather than powdered adsorbents. Mesoporous silica and branched polyethyleneimine [...]

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 [...]

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 [...]

Colloidal Structure-directing-agent-free Hydroxy-sodalite Nanocrystals

Yao J.F., Wang H.T., Monash University, AU

This presentation describes a unique approach to the synthesis of colloidal structure-directing-agent-free hydroxy-sodalite nanocrystals by using silicalite nanocrystals as a silica source.Under the aid of TPAOH molecules trapped in the dried silicalite nanocrystals, the silicalite [...]

Synthesis of new Metal Complex – Biomolecule Hybrids as Redox Sensors for Specific Nucleobases

Gasser G., Bond A.M., Graham B., Kosowski Z., Spiccia L., Monash University, AU

There are a number of redox-active supramolecular receptors described in the literature, but those containing ferrocene as a redox-active reporter group are the most frequently cited. It has been shown that modified ferrocenyl conjugates can [...]
