Shape Of Nanoparticles

This paper attempts to demonstrate the importance of the nanoparticle charge in the synthesis flame, for the mechanism of their evolution during formation processes. An investigation was made of MgO nanoparticles formed during combustion of magnesium particles. The cubic shape of nanoparticles in an unaffected flame allows for direct interpretation of results on the external flame charging, using a continuous unipolar emission of ions. It was found that the emission of negative ions applied to the flame strongly affects the nanoparticle shape, while the positive ions do not lead to any noticeable change. The demonstrated effect emphasizes the need to take into account all of the phenomena responsible for the particle charge when modeling the nanoparticle formation in flames.

In this paper, we investigate the plasmonic coupling effects on the localized surface plasmon resonances (LSPRs) of palladium nanoparticle chains. We show the transmission electron microscopy (TEM) images and the extinction cross-section spectra of near-contact palladium nanoparticle chains from monomer to pentamer. The extinction spectra of chains nanoparticles were measured by far-field polarization spectroscopy over a large spectral range (ultraviolet, visible and near-infrared) and compared with numerical calculations based on finite element method (FEM). For single palladium nanoparticle, the LSPR phenomenon appears in ultraviolet region. By addition of palladium nanoparticles to the chain, we observe a tunable red-shifting on the spectral position due to plasmonic coupling between palladium nanoparticles and a systematic spectral amplitude enhancement with the appearance of new modes of resonance.

Step Heat Treatment

Fine powders of intermetallic NiAl and Ni3Al were synthesized through organometallic precursors, which were coprecipitated from aqueous solutions of NiCl2 and AlCl3 by the addition of ammonium benzoate and hydradinium monochloride as precipitants. Ni3Al and NiAl were synthesized by a two-step heat treatment of the precursors. The initial step was the thermal decomposition of organic groups to form homogeneous mixtures of Ni3C, amorphous Al2O3, and free C below 1000 °C. The other step was the reaction above 1300 °C to form the intermetallics. Single phase powders of NiAl and Ni3Al with the particle size less than 3 μm were obtained above 1300 and 1400 °C, respectively.
