Highly Flexible Transparent Thin Film Heaters based on Metallic Nanowires

We demonstrate that flexible transparent film heaters (TFHs) with excellent performances can be fabricated from solution-processible metallic nanowire thin films. The TFHs were first deposited on glass and heating performances were monitored at different applied [...]

A Novel High Yield Process for Gold Sulfide Nanoparticle Synthesis via Shifting Equilibrium of Self-Assembly Reaction

Patel D., James K., Zhang G., Gobin A.M., University of Louisville, US

This project is focused on the scale up of gold-gold sulfide (GGS) nanoparticles with desired near infrared peak (nIR) that can be used for therapeutic applications. By combining published methods for 1-step self-assembly of GGS [...]

Synthesis and characterization of copper oxide decorated zinc oxide nanorods

Lim S.K., Hong S.H., Hwang S.H., Kim H-S, Kim S., Lee D.J., Kim H-S, Kim S., DGIST(Daegu Gyeongbuk Institute of Science & Technology), KR

One-dimentional nanostructures in the form of nanorods, nanowires, nanofibers or nanotubes, appear as an exciting research area for their great potential of applications. Zinc oxide is an n-type semiconductor that has been well known for [...]

Nanogel Star Polymer Nanostructures of Controlled Size, Molecular Architecture and Functionality: No Assembly Required

Miller R.D., Sly J., Lee V.Y., Appel E., Nguyen T., Nunes H., Tjio M., Gomez L., McNeil M., Munninghoff J., Rowan A.E., IBM Almaden Research Center, US

We have developed versatile routes to nanogel core, multiarm star polymeric unimolecular amphiphiles that provides exquisite control over molecular size, polydispersity, chain and periphery functionality which eliminate the dynamic equilibrium associated with polymeric micelles. . [...]

Pulsed laser generation of clean colloidal metal nanoparticles

Bärsch N., Bartke D., Barcikowski S., Particular GmbH, DE

In contrast to colloidal chemistry, pulsed laser ablation in liquids is a physical process that generates nanoparticles e.g. from precious metals or alloys directly in water or organic solvents. Zeta potential values up to -80 [...]

Rapid Combustion Synthesis of Zinc Oxide Nanostructures

Merchan-Merchan W., Farmahini Farahani M., University of Oklahoma, US

In this contribution we show that Zn oxide nanostructures of various morphologies can be formed at high rates by using a counter-flow flame. A 1.0-mm in diameter Zn probes with a purity of ~99.99% is [...]

Iron-oxide nanoparticle synthesis from liquid spray flames under variable pressure conditions

Hardt S., Wiggers H., Wlokas I., Kempf A., Schulz C., University of Duisburg-Essen, DE

Iron-oxide nanoparticles have been synthesized via liquid-fed flame spray pyrolysis (FSP) under variable pressure conditions. The work focuses on the effect of pressure, precursor flow rate, and flame stoichiometry on particle size, composition, and morphology. [...]

Synthesis and characterization of carbon nanotubes by catalytic decomposition of acetylene with Fe/Co/MgO, Co/Zn/Al and (C5H7O2)3Mn/Al as catalysts

Dikio E.D., Vaal University of Technology, ZA

We report our studies on the effect of various catalysts in the synthesis of carbon nanomaterials. The as-prepared carbon nanomaterials were characterized by Raman spectroscopy, high resolution transmission electron microscopy and X-ray diffraction. The catalysts [...]

Comparative Analysis for Pseudoboehmite Obtainded by Sol Gel Using Green Chemistry Expert System Sofware

Serna Saiz J., Camargo G., Moreno J.C., Suarez A.F., Universidad Libre, CO

Monohidróxide aluminum, known as pseudoboehmite (AlOOH) was obtained by the sol-gel method by the reaction between aluminum and isopropyl alcohol to produce aluminum isopropoxide using mercuric iodide and Iodine sublimed as catalyst. This work looks [...]
