A unique opportunity for industrial scale fabrication of semiconductor nanowire-based devices

Nikoobkht B., National Institute of Standards and Technology, US

A method is developed which enables horizontal growth of semiconductor nanowires on predefined locations. In this architecture, despite most bottom-up approaches, there is no need for post-growth treatments and alignment of nanowires on a given [...]

InSb and GaInSb nanowires for thermoelectric applications

Ye Q.L., Scheffler R., Kumari J., Leverenz R., NASA Ames Research Center, US

One-dimensional III-V compound semiconductor nanowires are an important class of nanomaterials that possess unique structures, remarkable properties, and great potential in various applications. InSb represents the smallest band-gap III-V compound semiconductor (0.17 eV at room [...]

One-dimensional Phase-Change Nanowires for Information Storage Application

Sun X.H., Yu B., NASA Ames Research Center, US

The electrically operated phase-change random access memory (PRAM) features faster write/read, improved endurance, and much simpler fabrication as compared with the traditional transistor-based nonvolatile semiconductor memories. Low-dimensional phase-change materials in nanoscale dimensions offer advantages over [...]

Gas Sensor Arrays by Supersonic Cluster Beam Deposition

Barborini E., Leccardi M., Bertolini G., Rorato O., Franchi M., Bandiera D., Gatelli M., Wegner K., Raso A., Garibbo A., Ducati C., Piseri P., Milani P., Tethis S.r.l., IT

Supersonic cluster beam deposition was employed to produce nanostructured thin films of transition metal oxides to be used as gas sensors. The cluster beam was generated by a pulsed microplasma cluster source equipped with aerodynamic [...]

Nano-Engineering Of Magnetic Particles For Biocatalysis And Bioseparation

Yu C.H., Lo C.C.H., Yeung C.M.Y., Tam K., Tsang S.C., University of Reading, UK

Magnetic nanoparticles encapsulated in a thin coating as magnetic separable nano-vehicle for chemical species is a hot but challenging area. The stability of the small magnetic body remains a key issue. In this meeting, we [...]

A search of superparamagnetic iron oxide-myoglobin as potential nanoparticle based magnetic resonance imaging marker in mouse heart imaging

Sharma R., Haik Y., Chen C-J., FAMU-FSU College of Engineering, US

Superparamagnetic iron oxide (Fe2O3) has emerged as potential MRI contrast agent in whole animal imaging to localize the site of clinically important physiological damage such as ischemia, angiogenesis, oxygen insufficiency, immuno-deficiency [1, 2]. We achieved [...]

Lattice Constant Dependence on Particle Size for Bulk and Doped Ceria prepared from a Citrate Sol-Gel

Morris M.A., Morris V.N., Farrell R.A., Sexton A.M., Morris M.A., Morris V.N., Analog Devices, Dimensional Solids Group, UCC, IE

High surface area ceria nanoparticles have been prepared using a citrate sol-gel precipitation method. Changes to the particle size have been made by calcining the ceria powders at different temperatures, and X-ray methods used to [...]

A Simple Method to Prepare Template-removed Zeolite MFI Nanomaterials

Li Q., Wang J., Yuan H., Shanghai Second Polytechnic University, CN

A method of non-thermal, photochemical calcinations is described for an efficient and spatially controlled removal of the organic template in the preparation of zeolite MFI nanoparticles and thin films. High silica MFI nanoparticles and thin [...]
