Synthesis and Characterization of Single Wall Carbon Nanohorns Produced by Direct Vaporization of Graphite

Pagura C., Schiavon M., Barison S., Battiston S., Consiglio Nazionale delle Ricerche, IT

A new patented process for massive production of single wall carbon nanohorn (SWCNH) is presented. Without any catalyst, the prototipe plant is able to produce 100 g/h of high purity carbon nanohorns. The direct vaporization [...]

Fluorescence Based Specific PNA-DNA Binding Characterization on nano-FET DNA Device Surface

Rastogi S.K., Mishra N.N., Finaloski B., Cameron E., Maki W., Postdoc Researcher, US

A novel sequence of peptide nucleic acid (PNA; beta-Ala-(T10)-beta-Ala-NH2) containing ten thymine monomers and beta-alanine amino acid at both (C and N) terminal of main chain was synthesized manually using solid phase tBoc peptide chemistry. [...]

Organic Solvent Dispersed TiO2 Nanocrystal Sol: Synthesis and Characterization

Rao Y.Q., Antalek B., Minter J., Mourey T., Blanton T., Slater G., Slater L., Slater G., Slater L., Fornalik J., Eastman Kodak Company, US

Anatase TiO2 nanocrystals with a mean diameter of about 10 nm were successfully synthesized through a non-aqueous sol gel route without the use of air free equipments. The nanocrystals were well dispersed in organic solvents [...]

The Morphology and Evolution of Zinc Oxide Flowers Like by Direct Synthesis and Sequential Nucleation Growth

Elizondo N., Obregon R., Perez E., University of North Texas, US

The morphology evolution characteristics of ZnO nanostructures were systematically studied from dense rods to ZnO flowers like. The ZnO flowers like were prepared by direct decomposition of a Zn(OH)42– precursor. Zinc oxide with a diversity [...]

Synthesis and Characterization of Co-Zn Ferrite Nanocrystals for Magnetocaloric Applications

Urcia-Romero S., Renteria B., Gutiérrez G., University of Puerto Rico, PR

Cobalt ferrite (CoFe2O4) is known for its high coercivity, chemical stability and high sensitivity of its Curie temperature (TC) with Zn-doping. A ferrofluid bearing this type of ferrite nanocrystals could be then considered good candidate [...]

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 and Self-Assembly of Biodegradable Poly(ethylene oxide)-b-Polycaprolactone (PEO-b-PCL) Diblock Copolymers

Li G., Ghoroghchian P., Qi W., Christian N., Frail P.R., Hammer D.A., Therien M.J., Carestream Health Inc., US

A series of amphiphilic poly(ethylene oxide)-b-polycaprolactone (PEO-b-PCL) diblock copolymers with various PEO blocks (number-average molecular weight (Mn): 750~5800), PEO weight fraction (fPEO) from 7.7% to 33.3%, and Mn of the copolymers from 3.6k to 57k, [...]

Silver Nanoparticles Synthesis from Highly Concentrated Solutions

Klein G., Meyer E.M., Si-Ahmed L., Metalor Technologies SA, CH

Silver nanoparticles are nowadays of great interest; either for their antibacterial properties or as a conductive filler in electronic applications. In both cases, silver nanoparticles have to be optimally dispersed in a polymeric matrix while [...]

A Novel Method for the Production of a Vast Array of Metal, Metal Oxide, and Mixed-Metal Oxide Nanoparticles

Woodfield B.F., Liu S., Boerio-Goates J., Astle L., Brigham Young University, US

In this paper we discuss the materials that can now be produced using a novel method for producing large quantities of high-purity metal, metal oxide, and mixed-metal oxide particles. These nanoparticles are uniform in size [...]

A Revolutionary New Method for the Synthesis of a Wide Array of Metal Oxide and Mixed Metal Oxide Nanoparticles with Sizes as Small as 1 nm

Woodfield B.F., Liu Q., Liu S., Liu Q., Liu S., Astle L., Boerio-Goates J., Brigham Young University, US

We have developed a revolutionary new method for the production of large quantities of high-purity metal, metal oxide, and mixed-metal oxide nanoparticles. Particles are uniform in size with dimensions that can range from 1 nm [...]
