Synthesis of Dy2O3 nanocrystalline powder using Acrylamide assisted combustion route

Vijayakumar M., Nallamuthu N., Venkateswarlu M., Satyanarayana N., Pondicherry University, IN

Nanocrystalline Dy2O3 powder was synthesized using arrylamde assisted combustion process. The prepared nano crystalline Dy2O3 powder was characterized through XRD, FTIR and SEM-EDX elemental mapping measurements.

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 [...]

Effect of Rare Earth Doping on Magnetic Properties of Cobalt Ferrite Nanocrystals

Cedeño-Mattei Y., Uwakweh O.N.C., Osorio-Cantillo C., University of Puerto Rico-Mayagüez, PR

Cobalt ferrite (CoFe2O4) is a highly anisotropic magnetic material due to the magnetocrystalline anisotropy contribution from Co2+. The addition of foreign cations of different oxidation states, substituting Co2+ or Fe3+, can lead to an atomic [...]

Flame Synthesis and Coating of Nanostructured Particles in One Step

Teleki A., Buesser B., Heine M., Krumeich F., Akhtar M.K., Pratsinis S.E., ETH Zürich, CH

Coating of flame-made nanostructured particles has been achieved in one step by a scalable aerosol process. Rutile TiO2 particles made by flame spray pyrolysis (FSP) were coated in a single step with SiO2 layers in [...]

Colored nanoparticles:composition and application to protein fibres and hair

Gomes J., Sampaio S., Maia F., University of Minho, PT

The coloration of hair is usually done with dyes that need harsh post treatments with products such as ammonia, so as to have durability. In this work, we have developed nanoparticles (medium range 200 nm), [...]

Measurement of nanofiller removal by abrasion

Tardif F., Guiot A., Golanski L., CEA-Liten, FR

A strong release limitation of single nanoparticles from the commercial manufactured “nanoproducts” is absolutely necessary to protect the consumers and represents also a pragmatic way to facilitate acceptance for nanomaterial commercialization before obtaining definitive toxicological [...]

Degradation and Nanoparticle Release of Epoxy/Nanosilica Composites Exposed to Solar UV Radiation

Pellegrin B., Nguyen T., Mermet L., Shapiro A., Gu X., Chin J., NIST, US

Nanoparticles are increasingly incorporated in polymers to enhance multifunctional properties. However, polymers are prone to undergo photodegradation under UV exposure, resulting in a liberation of nanoparticles from the polymer nanocomposites during their life cycle. The [...]
