Multifunctional Nanostructures and Nanoarchitectures

Hunyadi Murph S.E., Savannah River National Laboratory, US

The development of functional nanomaterials with multi-detection modalities opens up new avenues for creating multi-purpose technologies for many applications. The “ideal” nanoparticle would combine multiple detection modalities (magnetic, plasmonic, elastic or inelastic light scattering, fluorescence, [...]

Synthesis and Characterization of Copper-Copper oxide nanofluids in the confinement regime

Babukutty B., Parakkal F., Bhalero G.M., Nair S.S., Central University of kerala, IN

Abstract: Copper oxide shelled copper nanofluids are synthesized with surfactant trioctylphosphine oxide (TOPO) using sulphates precursors. The fluids were structurally characterised by X-ray Diffraction (XRD). Surface and morphological characterization are carried out by Scanning Electron [...]

Hydrothermal Synthesis of Silver Nanowires and Application as Transparent Conductive Materials

George A.L., McGough P.T., Lunn J.D., Wang W., Kuo T.-C., Todd C.C., Goss J.M., Collins R.M., Malek A., Calverley E.M., The Dow Chemical Company, US

A scalable hydrothermal synthesis for silver nanowires has been developed. The new synthetic route is expected to be compatible with industrially available reactor systems and offer environmental and safety advantages due to use of aqueous [...]

Low turn-on field of ZnO nanostructures grown with catalyst-free vapor-phase transport

Yang S-H, Hsu Y-M, Tsai M-W, Chang L-L, Chiang P-J, National Kaohsiung University of Applied Sciences, TW

Low turn-on electric field of ZnO nanostructures were grown with pseudo-catalyst by vapor phase transport. A ZnO:Al (AZO) seed layer was deposited on a silicon substrate by RF magnetron sputtering, which formed nucleation sites and [...]

Scale-up of metal nanoparticle production

Stein M., Kruis F.E., University of Duisburg-Essen, DE

Metal nanoparticles are used in numerous products and applications to enhance their performance or efficiency. Different gas phase synthesis routes are known to form metal nanoparticles, however only few are capable for scaling-up in terms [...]

Effect of flame-made metal (M = Pt, Nb, Ru) -loaded In2O3 on NO2 gas sensing

Phanichphant S., Chiang Mai University, TH

Unloaded In2O3 and M-loaded (M = Pt, Nb and Ru) In2O3 nanoparticles loaded with 0.25–1.00wt% metal were successfully synthesized in a single step by the flame spray pyrolysis (FSP) technique. Unloaded In2O3 and M-loaded (M [...]

Catalytic oxidation of carbon using TiO2 based nanoparticles prepared using flame synthesis

Memon N.K., Ismail M.A., Anjum D.H., Chung S.H., Qatar Environment and Energy Research Institute, QA

Titanium dioxide (TiO2) nanoparticles are used in numerous applications involving catalysis, photo-catalysis, water purification, electrode for Li-ion batteries, polymer fillers, and pigments. Multiple-diffusion flames are used to coat/dope the TiO2 nanoparticles with various elements such [...]

Investigation of interaction between graphene and steel using Raman Spectroscopy

Fushiwaki Y., Abdelkader A.M., Young R.J., University of Manchester, UK

The purpose of this study is to understand interaction between graphene and sheet steel by the use of Raman Spectroscopy. First of all, the graphene was put on the polished steel. Secondly, it was inspected [...]

Modeling of spontaneous phase separation in nanomaterials and confined systems with electron correlations

Kocharian A.N., Fang Kun, Fernando G.W., Balatsky A., California State University Los Angeles, US

The modeled of many body physics and possible spontaneous phase separation instabilities in various two-dimensional square and honeycomb structures (generated by periodically repeated Betts lattices) provide an ideal playground for understanding of various competing phases [...]

Manganese Oxide/Carbon Nanofibers-Embedded Graphene Sheets for Capacitors

Ahn K-J, Yoon H., Chonnam National University, KR

We report the fabrication of a ternary nanoarchitecture consisting of manganese oxide (MnO), carbon nanofibers (CNFs), and reduced graphene oxide sheets and their application to supercapacitor electrodes. MnO nanoclusters-decorated CNFs (MCNFs) with diameters of about [...]
