A simple route to synthesize impurity-free high-oriented SiOx nanowires

Chiu S.C., Li Y.Y., National Chung Cheng University, TW

Impurity-free silicon oxide nanowires were synthesized on a 3 cm x 3 cm alumina plate uniformly by thermal evaporation of a mixture of powder of graphite powders and Si-SiOx particles under argon atmosphere with a [...]

Growth _–Fe2O3 nanowires with different crystal direction of iron film

Hsu L.C., Li Y.Y., National Chung Cheng University, TW

–Fe2O3 nanowires (NWs) were synthesis from different crystal direction of iron film by thermal oxidation in oven. The crystal direction of iron film was successfully control by sputtering 50 nm iron on different direction of [...]

Low temperature synthesis and characterization of large scale ZnMgO nanowire architectures

Shimpi P., Gao P-X, University of Connecticut, US

Large scale hexagonal ZnMgO nanowire array and network with tunable shapes has been successfully synthesized on solid Si substrate, and flexible substrates (Au and Pd coated plastic substrates) using low temperature hydrothermal synthesis technique. The [...]

Synthesis of uniform ZnO nanowire arrays over a large area

Wang C-H, Yang J., Shum K., Salagaj T., Ren Z.F., Tu Y., First Nano, US

It has been found that Zinc oxide (ZnO) nanowires have great potential in many applications. Currently, the most commonly used method to grow ZnO nanowires is to use the vapor transport method. The morphology of [...]

Morphological, Crystalline and Photo-luminescent Property of Zinc Oxide Nanorod Array Controlled by Zinc Oxide Sol-gel Thin Film

Huang J-S, Lin C-F., National Taiwan University, TW

Our work provides a systematic study of controllable morphology, crystallinity and photoluminescence (PL) of ZnO nanorod array. Our investigation demonstrates that the pre-treatment conditions of the ZnO sol-gel thin-film have strong influences on the morphology, [...]

Synthesis and Propertie of CNT Yarns and Sheets

Lashmore D., Schauer M., White B., Braden R., Nanocomp, US

We have developed an automated CVD process based on gas phase pyrolysis for the synthesis of high strength carbon nanotubes based sheets and yarns. This has led to a unique process for continuous production of [...]

Optical properties of [001] GaN nanowires- An ab-initio study

Agrawal B.K., Agrawal S., Pathak A., Agrawal B.K., Agrawal S., Allahabad University, IN

We study the physical properties of the unpassivated and H-passivated GaN nanowires (NWs) by employing the first–principles pseudopotential method within density functional theory (DFT). Two types of the NW’s having hexagonal and triangular cross-sections have [...]

Some Properties of Electro-Deposited Fullerene Coatings

Ershova O.G., Khotynenko N.G., Golovko E.I., Pishuk V.K., Mil’to O.V., Kopylova L.I., Vlasenko A.Yu., Institute for Problems of Materials Science of NAS of Ukraine, UA

Earlier we have demonstrated the principal possibility to produce fullerene-containing coatings on metal electrodes by the electrochemical method and the dependence of their structure on the chemical composition of the working solution and experimental conditions. [...]

Preparation and applications of transition metal oxide nanofibres and nanolines

Tätte T., Paalo M., Part M., Kisand V., Lõhmus A., Kink I., University of Tartu, EE

Recently many nanoscale silica structures have been suggested for optics device design. For example silica nanoneedles are used for focusing light into spot some tens of nanometers in diameter and sub-wavelength diameter silica fibres are [...]

Synthesis of Carbon Nanostructures in Liquid Helium

Schur D.V., Bogolepov V.A., Savenko A.F., Institute for Problems of Materials Science of NAS of Ukraine, UA

At present synthesis of carbon nanostructures is mainly performed in different scientific groups by any one method. For this reason not everyone has possibility to compare peculiarities of synthesis of the same product by different [...]
