New Generation Nanogold and Nanosilver Polymer Composites and Their Applications

Johnston J.H., Parry M., Victoria University of Wellington, NZ

A new generation of nanogold and nanosilver polymer composites with polyurethane and nylon, and nanofunctionalised polyurethane paints, have been developed. This novel nanoscience provides the opportunity to impart new functionality to these polymer substrates for [...]

Novel Syntheses of Silica-Gold Core-Shell Particles

Cook M.J., Johnston J.H., Victoria University of Wellington, NZ

Methods for the synthesis of silica-gold core-shell particles presented in literature are not considered commercially viable due to various requirements: high reaction temperatures, the use of light-sensitive reagents, the use of ex-situ gold seeding adding [...]

Synthesis and Characterization of Copper (i) Oxide and Zinc Oxide Quantum Dot Materials and the Development of New Fluorescent Fibre Composites

Johnston J.H., Zeller A.J., Victoria University of Wellington, NZ

New fluorescent composites of Cu2O and ZnO quantum dots with wool and paper fibres for potential use in photoluminescent fabrics, packaging and labelling papers, have been developed. The fluorescent colours can be tuned by varying [...]

Recovery of phosphate from surface waters using a calcium silicate composite material for potential application in environmental remediation

Cairns M.J., Krauss C., Johnston J.H., Victoria University of Wellington, NZ

In many locations, contamination of surface waters by phosphate due to agricultural run-off is becoming a major environmental concern. Currently, there are no effective means for its removal, due to the low phosphate concentration (< [...]

Superhydrophobic and Superhydrophilic Surfaces

Herzog M.B., Johnston J.H., Franzreb M., Victoria University of Wellington, NZ

A new generation of materials possessing a wide range of possible consumer applications such as water harvesting, stain resistant self-cleaning and water-repellent breathable surfaces are being fabricated. Based on nature’s example of the stenocara beetle, [...]

New Fluorescent Hybrid Materials Comprising Quantum Dots, Organic Fluorophores and Natural Fibre Substrates

Zeller A.J., Johnston J.H., Victoria University of Wellington, NZ

The nanotechnology research presented here deals with the development and characterisation of new fluorescent hybrid materials comprising quantum dots and organic fluorophores respectively with wool and paper fibres that exhibit tuneable optical fluorescence and electronic [...]

Characterization of palladium nanoparticles embedded in a wool substrate

Fonseca-Paris C., Johnston J.H., Victoria University of Wellington, NZ

In the present paper we report the characterization of nanopalladium-wool fibre composites. Professor James Johnston and his research group at Victoria University of Wellington have developed a new methodology to reduce metal salts of palladium [...]

Silver Chloride – Wool Nanohybrid Materials: Synthesis and Properties

Johnston J.H., Kelly F.M., Victoria University of Wellington, NZ

The development and characterisation of a new nanowool hybrid material formed by functionalising merino wool with silver chloride nanoparticles is presented. The nanoparticles are formed directly on the surface and inside the wool fibre. Initially [...]

Nanogold and Nanosilver Wool: New Products for High Value Fashion Apparel and Functional Textiles

Johnston J., Burridge K., Kelly F., Small A., Victoria University of Wellington, NZ

ORAL We have developed a new proprietary nanotechnology and product suite of high value textiles involving the use of nanogold and nanosilver as colourants and functional components in wool. This innovatively links the high value [...]
