Synthesis, Extraction and Surface Modification Of (Zn,Mn)Se Nanocrystals Using Microemulsions As Templates

Heckler T., Qiu Q., Wang J., Mei B., Mountziaris T.J., University of Massachusetts, US

This research focuses on the novel room temperature synthesis of (Zn,Mn)Se quantum dots that exhibit luminescence peaks at longer wavelengths than the ZnSe bulk emission, due to the Mn ions incorporated in the ZnSe lattice. [...]

Emulsions as Templates for Nanostructured Materials

Solans C., Esquena J., Nolla J., CSIC, ES

The preparation of nanostructured materials by emulsion templating is of particular interest among the soft nanotechnology processes. The use of emulsions allows good control of size and morphology, mild reaction conditions and technological feasibility. This [...]

Silver Nanoparticles Synthesis from Highly Concentrated Solutions

Klein G., Meyer E.M., Si-Ahmed L., Metalor Technologies SA, CH

Silver nanoparticles are nowadays of great interest; either for their antibacterial properties or as a conductive filler in electronic applications. In both cases, silver nanoparticles have to be optimally dispersed in a polymeric matrix while [...]

Gold Nanoparticles as Colourants in High Fashion Fabrics and Textiles

Johnston J.H., Richardson M.J., Burridge K.A., Kelly F.M., Victoria University of Wellington, NZ

Gold nanoparticles which exhibit different colours due to surface plasmon resonance scattering effects are used here as stable colourants on wool and synthetic fibres. This provides the exciting opportunity to link nanoscience with high value [...]

Development of Nanoparticle-Based Gold Contrast Agent for Photoacoustic Tomography

Yang Y.-S., Vaithilingam S., Ma H.T.-J., Khuri-Yakub B.T., Guccione S., Stanford University, US

Photoacoustic tomography (PAT) utilizes non-ionizing energy to obtain structural/functional information with high spatial resolution and sensitivity. Heterogeneous absorption of optical energy in biological tissues results in differentially expressed acoustic signals yielding spatial/temporal information. A critically [...]
