Growth of 3C-SiC Nanowires on Nickel Coated Si(100) Substrate using Dichloromethylvinylsilane and Diethylmethylsilane by MOCVD Method
3C-SiC nanowires have been deposited on nickel coated Si(100) substrates using single source precursors by thermal metal-organic chemical vapor deposition (MOCVD) method. Dichloromethylvinylsilane (CH2CHSiC(CH3)Cl2) and diethylmethylsilane (CH3 SiH(C2H5)2) were used as a single precursor without [...]

Chang H., In E., Kong K-J, Lee J-O, Choi Y., Ryu B-H, Korea Research Institute of Chemical Technology, KR
First principles calculations are used to predict the stability and electronic structures of SnS2 nanotubes. Optimization of several structures and their corresponding strain energies confirms the stability of SnS2 nanotube structures. Band structure calculations show [...]
Surface Plasmon Absorption of Metallic Nanostructures in an Amplifying Medium
Numerous applications that rely on the local field enhancement associated with the Surface Plasmon Resonance (SPR) have been suggested. With host material being an integral part in forming SPR, systems with optically transparent host have [...]
Bulk Nanostructured Metals by Severe Plastic Deformation (SPD)
The top-down methods of “Severe Plastic Deformation (SPD)” have been shown to have the potential for directly converting conventional metals into submicron- or nano-scaled bulk materials. These techniques exhibit significant advantages compared to bottom-up ones: [...]
Fabrication of Metal Oxide Coaxial Nanotubes using Atomic Layer Deposition
We fabricated of nanotubular structures of TiO2 and ZrO2 using the gas-phase fabrication method atomic layer deposition (ALD) with nanoporous structure of polycarbonate (PC) templates. Contact printed alkylsiloxane monolayers on both sides of PCs were [...]
Synthesis of Nickel Nanoparticles by Reduction of a Organometallic Precursor with Hydrogen
In this work, a new method of synthesis of metallic nanoparticles of nickel is reported. It has been achieved in an organic solution in the presence of non-ionic surfactant with hydrogen as reductor agent, our [...]
Novel Method for the Electrochemical Synthesis of Nickel-Rich Oxide Nanowires
Thorne S.A., Bhargava Y.V., Mintz T.S., Radmilovic V., Suzuki Y., Devine T.M., University of California-Berkeley, US
Using a novel electrochemical process, functionalized and self-assembled Ni-rich oxide nanowires were grown from an Alloy 600 (Ni – 15.5 a/o Cr, 8a/o Fe) substrate. The formation of the nanowires occurs in a high-temperature (238-288 [...]
Conductive Films of Ordered High-Density Nanowire Arrays
Kulkarni J.S., Daly B., Ziegler K.J., Crowley T., Erts D., Polyakov B., Morris M.A., Holmes J.D., University College Cork, IE
We have prepared high-density, ordered arrays of semiconductor nanowires within the pores of mesoporous thin films (MTFs) and anodized aluminum oxide (AAO) matrices using a supercritical fluid solution-phase inclusion technique. Conductive atomic force microscopy (C-AFM) [...]
IrO2 Nano Structures by Metal Organic Chemical Vapor Deposition
This paper will discuss the deposition of IrO2 nano structures using (methycycpentadienyl) (1, 5-cyclooctadiene) iridium as the precursor and using Metal Organic Chemical Vapor Deposition (MOCVD) method with no template. Three different shapes of IrO2 [...]
