New Nanocomposites – Controlled Capture of Nanoparticles in Scrolled Nanosheets

Adireddy S., Yao Y., Vargas J.M., Spinu L., Wiley J.B., University of Neworleans, US

The ability to encapsulate linear nanoparticle chains in scrolled nanosheets is an important advance in the formation of nanocomposites. Recent work in our group resulted in the in situ formation of peapod-like structures based on [...]

The Characteristics and Photocatalytic Activity of Visible Light Driven N-doped TiO2

Hsu H-J, Lin Y-H, Lin Y.-T., Lin Y-H, Lin Y.-T., National Chung Hsing University, TW

In the recent decades, titanium dioxide (TiO2) nano-material was received widely attention because of its good chemical stability, low-toxicity, self-cleaning, anti-bacteria and deodorant. However, its photocatalytic activity was limited only by ultraviolte (UV) light irradiation [...]

Nanoparticle synthesis using polyelectrolyte nanoreactors

Anderson D.J., Dinglasan J., Goh J.B., Goh M.C., Veletanlic E., Goh J.B., Goh M.C., Vive Nano, CA

We report a facile method to synthesize a wide range of nanoparticles via polyelectrolyte nanoreactors. The nanoreactors are formed through ion-induced collapse of highly extended, high molecular weight anionic polyelectrolytes using metal salts. The formation [...]

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 [...]

Nanostructured photocatalytic TiO2-xNx thin films prepared by reactive magnetron sputtering

Teodorescu C.-M., Luca D., National Institute of Materials Physics, RO

Nitrogen-doped titania films were grown by magnetron sputtering. XPS analysis was used to identify the nitrogen content and the oxygen stoichiometry of the samples. XANES evidenced an increase of the Ti 3d charge density. XRD [...]
