Synthesis and Testing of Metal and Nitrogen Doped Nano-TiO2

Zhang Z., Darr J.A., University College London, UK

we have adopted a novel approach to the use of continuous hydrothermal flow system (CHFS) for the synthesis of various crystalline doped anatase TiO2 nano-ceramics with high surface area (ca. 280 m2g-1) system. Their photocatalytic [...]

Synthesis of Porous Nanostructured Silica Particles by an Aerosol Templating Method

Jang H-D, Chang H., Park J.H., Kim T-O, Okuyama K., Korea Instittute of geoscience and Mineral Resources, KR

Silica nano-materials with meso- and macroporosity are of great interest due to their variety of potential applications. For the application as a catalytic supporter, nanostructured spherical silica particles having both mesopores and macropores were prepared [...]

Synthesis of Nanopowders and Their Production at the Industrial Scale Using the Inductively-Coupled Plasma Technology

Dolbec R., Bolduc M., Fan X., Guo J., Jurewicz J., Xue S., Boulos M., Tekna Plasma Systems Inc., CA

The increasing demand for nanopowders (particles size

Two-nozzle flame synthesis of Pt/Ba/Al2O3 for NOx storage

Büchel R., Strobel R., Pratsinis S.E., Baiker A., ETH Zürich, CH

A novel two-nozzle flame spray pyrolysis (FSP) process is presented for one-step preparation of Pt/Ba/Al2O3 particles for NOx storage-reduction (NSR) catalysts. These storage catalysts are of particular interest for mobile engines operating under lean conditions [...]

Structure-Property Correlations in ZnO Tetrapods and Spheres prepared by Chemical Vapour Synthesis

Bacsa R., Bacsa W., Verelst M., Dexpert J., Bacsa R., Bacsa W., Serp P., CEMES CNRS Univ Toulouse, FR

ZnO is a direct band gap semiconductor that finds applications in varistors and arrestors. Efficient luminescence in the UV of high purity nanocrystalline ZnO nanoparticles (20-50nm) is used in medicine and in the cosmetic industry [...]

A Novel Method for the Production of a Vast Array of Metal, Metal Oxide, and Mixed-Metal Oxide Nanoparticles

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

In this paper we discuss the materials that can now be produced using a novel method for producing large quantities of high-purity metal, metal oxide, and mixed-metal oxide particles. These nanoparticles are uniform in size [...]

Using Scanning Thermal Microscopy Techniques for In-Situ synthesis of Carbon Nanotubes at “room temperature conditions”

Mukkisa S., Banerjee D., Texas A&M University, US

Carbon Nanotubes (CNT) were synthesized at room temperature conditions on a heated scanning probe without the use of conventional Chemical Vapor Deposition (CVD) apparatus or the process gases. The heated scanning probe is composed of [...]

Dip Pen Nanolithography® of Silver Nanoparticle Inks for Printed Electronics

Parpia M., Tevaarwerk E., Amro N., Wang H.T., Haaheim J., Rozhok S., Levesque T., Nafday O.A., NanoInk, US

Precision nanoscale deposition of biological, organic, and inorganic materials is a fundamental need in nanoscience research. Dip Pen Nanolithography® (DPN®) is an inherently additive, SPM-based technique, capable of producing nanoscale features with high resolution and [...]

A Novel Technique for Purification and Segregation

Mangir T., Chaves J., Chaves S., Khairatkar M., Chaves J., Chaves S., California State University Long Beach, US

In paper we describe a technique to purify and segregate carbon nano tubes (CNTs) from the iron impurities to use the CNTs for thin films. After extensive research into a proper and repeatable cleaning process [...]

Research on Preparation of Nano-Barium Titanate and Dielectric Property of Barium Titanate Ceramic Capacitor

Feng X., Liu X., Cui Y., Institute of Electronic Engineering, CN

In this paper ,a mild alcohol-thermal synthesis of nano-BaTiO3 from H2TiO3 and Ba(OH)2 at an Atmospheric Press was systematically studied and the optimized preparation conditions were obtained. When the reaction was carried out at a [...]
