Nanoparticle Synthesis & Applications

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 [...]

A High-throughput Electrospray Nozzle for Nanoparticle Production

Fu H., Hoerr R.A., Ryan P.J., Nanocopoeia, Inc, US

Electrospray is well-known for its capability of producing monodisperse particles with sizes ranging from a few nanometers to micrometers. Even though electrospray has been used in a wide range of research areas, its low throughput [...]

Flame Synthesized Nanostructured WO3 Thin Films for Photoelectrochemical Water Splitting

Ding J-R, Kim K.S., Kangwon Natonal University, KR

Tungsten oxide has been considered as a promising photoanode material for photoelectrochemcial water-splitting techonologies due to its ralatively favorable band gap position and good charge transport property and stablity in aqueous solution. Typically, 1-dimentional structure [...]

Preparation of Photocatalytic Silicon Core-shell Nanoparticles Covered by ZnS Shell in Solid-Gas Reaction

Dvorsky R., Praus P., Svoboda L., Matýsek D., Dropa T., Trojková J., Šollová K., VŠB-Technical University of Ostrava, CZ

For easy handling in some practical processes, active nanoparticles are usually deposited on surfaces of larger carrier particles. In our previous work, the particles of montmorillonite MMT with a mean size of 300 nm served [...]

Uniform Melt State Process For The Production Of Nanostructured Materials

Redjdal M., Hadidi K., Sundaram S.K., Amastan LLC, US

Existing processes for the production of nanostructured composite materials suffer from non-homogeneity of feedstock and non uniformity of thermal processing path. Amastan’s UniMelt™ process solves both problems through the use of uniform temperature profile microwave [...]

Nano-Silicon and Non-Oxide Ceramics Synthesis via Gas-phase Sodium Reduction Aerosol Reactor

Schimmoeller B., Massey K., Kodas T., Smith G., Kutsovsky Y., Cabot Corporation, US

The largest volumes of nano-particles in consumer products include carbon black for reinforcement applications (e.g. tires), silicon dioxide (SiO2) as rheology agent (e.g. silicones) and titanium dioxide (TiO2) in pigments and photocatalysts. All of those [...]

Nanobiotechlogy: Applications in Food Science and Engineering

Sadeghi R., Ansari S., Uzun S., Bozkurt F., Gezer P.G., Karimi M., Kokini J., University of Illinois at Urbana-Champaign, US

Quantum (QD) dots were conjugated to anti-gliadin antibody and used as a fluorescent probes to track gliadin protein in dough and baked bread samples. CLSM images showed significant changes in the distribution of gliadin within [...]

Gold Nanorods: A Journey Towards Successful Synthesis

Kolb A.N.D., Johnston J.H., Victoria University of Wellington/MacDiarmid Institute for Advanced Materials and Nanotechnology, NZ

Gold nanorods (AuNRs) are attracting substantial research interest due to their remarkable size- and shape-related optical properties. AuNRs in solution are brightly coloured but not golden whereby the precise colours of AuNRs depend on accurately [...]

Practical synthesis of nanomaterials and nanostructures

Rae A., Matteson J., Dansoh V., NanoMaterials Innovation Center, US

Nanoparticle and nanostructured coating synthesis is commonly hampered by complex processes or the need to use precursors which may not yet be registered under TSCA or REACH. There are, however, simple and practical processes using [...]
