1D transition metal oxide materials: preparation and applications

Tätte T., Paalo M., Talviste R., Kisand V., Saal K., Mäeorg U., Lõhmus A., Kink I., University of Tartu, EE

Recently many new technologies have been suggested for designing silica based optical devises in nanoscale. However, there are insuperable drawbacks in realizing optics based on silica (glass and quartz) because of their low refractive indexes. [...]

A Revolutionary New Method for the Synthesis of a Wide Array of Metal Oxide and Mixed Metal Oxide Nanoparticles with Sizes as Small as 1 nm

Woodfield B.F., Liu Q., Liu S., Liu Q., Liu S., Astle L., Boerio-Goates J., Brigham Young University, US

We have developed a revolutionary new method for the production of large quantities of high-purity metal, metal oxide, and mixed-metal oxide nanoparticles. Particles are uniform in size with dimensions that can range from 1 nm [...]

The Pulsation Reactor Process – Large Scale Production of Nano-Sized Metal Oxide Powders in a Single Step

Fischer G., Leidolph L., Weitz U., IBU-tec, DE

A pulsed thermal reactor process was developed to produce nano particles on an industrial scale. Different precursors were applied to obtain the desired product properties. The applied techniques (pulsation reactor) are explained and different applications [...]

Raman and Photoluminescence Spectroscopy Investigations of ZnO Nanostructures

Chen B., Chen C., Ng H.T., Chen B., Chen C., NASA Ames Research Center, US

One-dimensional inorganic nanowires are expected to play important roles in optoelectronic device applications. The unique properties such as grain boundary and high surface area of these nanostructures are clearly different from the corresponding bulk material. [...]

NanoActive Metal Oxides: Unique Materials with Unlimited Potential

Koper O.B., Rajagopalan S., NanoScale Materials, Inc., US

NanoActive materials are novel forms of metal oxides that possess extremely high surface areas (100-700 m2/g), defect-rich morphology (many corner and edge sites), large porosities (up to 1 cc/g), and small crystallite sizes (2-10 nm). [...]

Particle Characterization of Nanoscale Materials using Dynamic and Static Light Scattering

Bumiller M., DeLuca T., Mattison K., Rawle A., Malvern Instruments, Inc., US

Purpose: Novel materials with single particle dimensions at the nano scale are submitted to our laboratory on a regular basis. These samples include single walled nanotubes (SWNT), buckyballs, quantum dots and various metal oxides. Determining [...]
