Fabrication of Complex Diffractive Structures in an Organic-Inorganic Hybrid and Incorporation of Silver Nanoparticles

Scholes F.H., Smith F.L., Furman S.A., CSIRO Manufacturing and Infrastructure Technology, AU

Organic-inorganic hybrids have recently attracted considerable interest. These materials, which are synthesized by the highly versatile sol-gel process, consist of interpenetrating organic and inorganic networks at the nano- to molecular size scale. Incorporating photo-polymerizable groups [...]

Highly Dispersible Microporous Carbon Particles from Furfuryl Alcohol

Liu J., Yaoa J-F, Wanga H-T, Chan K-Y, The University of Sydney, AU

Molecular sieve carbons (MSCs or carbon molecular sieves) are a class of microporous, amorphous high-carbon materials, and they share with zeolites the ability to distinguish molecules on the basis of size and shape. MSCs have [...]

Effect of Nanoclay Content on Mechanical Behaviour of TGDDM Epoxy Nanocomposites

Huong N.T.P., Crosky A., Qi B., Kelly D., Li D.C., The University of New South Wales, AU

Exfoliated nanocomposites based on tetraglycidyldiamino diphenylmethane (TGDDM) cured by diethyltoluene diamine (DETDA) reinforced with 1-20 phr of a commercial nanoclay (I30E) were prepared. The effect of the nanoclay content on the compressive modulus of the [...]

Exploring the Structure-Function Relationship in Multifunctional Nanoparticles

Casey P.S., Roussow C.R., Boskovic S., Lawrence K.A., Turney T.W., CSIRO (CMIT), AU

Nanoparticles of ZnO are increasingly being used as a pigment and UV absorber in personal care products (e.g. sunscreens), coatings and paints, predominantly because their absorbance efficiency increases with decreasing particle size. However, whilst protection [...]

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 [...]

Multivalent Circular Aptamers: Versatile Nanostructures for Biomedical Applications

King G.C., Knox S.M., Williams B.B., Harris J., Gupta D.M., Di Giusto D.A., Gabutero E.R., Tyrelle G.D., Lai Y.-C., Aung M.T., McCutcheon S.T., Voelcker N., Le H.T.T., School of Biotechnology and Biomolecular Sciences, AU

Much recent interest has focussed on applications of DNA in nanotechnology, while chemical biologists have adapted evolutionary processes to generate aptamers, folded nucleic acids with molecular recognition properties similar to protein antibodies. As yet there [...]

Controlling the Photoactivity of Nanoparticles

Casey P., Boskovic S., Lawrence K., Turney T., CSIRO(CMIT), AU

The relative photoactivity of a series of nanophase ZnO powders with varying crystallite size (20-140nm) was determined using a chemical method based on the photobleaching behaviour of the stable radical 1,1-diphenyl-2-picrylhydrazyl (DPPH). It was confirmed [...]
