Silica-coated Ag nanoparticles by scalable flame technology

Sotiriou G.A., Camenzind A., Pratsinis S.E., ETH Zürich, CH

Silica coated silver nanoparticles have been synthesized in one step, by using flame spray pyrolysis. By controlling the production parameters, different sizes and different coating thicknesses were achieved. The particles were characterized with TEM/STEM, EDX [...]

Application of Magnetite nanoparticles (Fe3O4) as an optimizing agent for Bradyrhizobium japanicum Growing Rate (BGR)

Ghalamboran M.R., Ramsden J.J., Cranfield University, UK

The aim of this study was to investigate, whether magnetic nanoparticles effect increasing of Bradyrhizobium Growing Rate in liquid media, and so alters sensitivity to high pH and survival.Finally results showed that using of the [...]

Synthesis of monodispersed MFe2O4 (M=Fe, Co, Ni) ferrite nanoparticles: effect of reaction temperature on particle size

Altavilla C., Leone C., Sannino D., Sarno M., Ciambelli P., University of Salerno, IT

The possibility of preparing monodispersed transition metal-oxides nanoparticles covered by functionalized long chain organic molecules, in the sub size range of 20 nm, has recently open an entire field of research. In fact, inorganic core [...]

Current Development Studies of a Single-Walled Carbon Nanotube Reference Material At National Institute of Standards and Technology (NIST)

Spatz R.O., Zeisler R., Paul R.L., National Institute of Standards and Technology, US

Carbon nanotubes are promising candidates for numerous applications because of very unique nanostructures and possess remarkable mechanical and electronic properties. For this reason there is an urgent need for standards for carbon nanotube (CNT) manufacturers, [...]

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 [...]

Composition- and Size-Controlled Synthesis of Mn-Zn Ferrite Nanocrystals for Potential Magnetocaloric Applications

Calderón-Ortiz E., Perales-Perez O., Urcio S., University of Puerto Rico-Mayagüez, PR

The use of ferromagnetic fluid for cooling applications where the fluid can be pumped with no moving mechanical parts, using the magnetocaloric effect, can be a great advantage for many applications where maintenance or power [...]
