“…Smooth silver nanoshells can be made using a variation of the method reported by Zsigmondy. 17 The gold- decorated silica particles are mixed with a 0.15 mM solution of fresh silver nitrate (AgNO 3 ) and stirred vigorously. A small amount (typically 25-75 µL) of 37% formaldehyde is added to begin the reduction of the silver on to the gold particles on the surface of the silica particle.…”

The production of silica core-silver shell nanoparticles (silver nanoshells) by three different chemical methods is described. Each method produces a silver outer layer with a unique morphology, ranging from smooth and uniform, to rough on the 2-5 nm length scale, to spiky with extremely sharp, needlelike protrusions extending outward from the surface of the nanoparticle. The nanoshells produced by each growth method were studied using transmission electron microscopy and UV-vis spectroscopy. In particular, one reduction method produced silver nanoshells with smooth and highly uniform morphologies whose optical extinction corresponded quantitatively to Mie scattering theory for a silica core-silver shell nanostructure.

“…The standard spinel ferrite pattern is presented below indicating both peak positions and relative amplitudes. Particle diameters, estimated from x-ray diffraction Scherrer analysis [38], and by direct imaging using transmission electron microscopy (TEM), were found to range from 4 to 50 nm. The inset to figure 1 illustrates a TEM image of nanoparticles taken from the same sample used in data collection of the XRD spectrum.…”

Mn ferrite (MnFe(2)O(4)) nanoparticles, having diameters from 4 to 50 nm, were synthesized using a modified co-precipitation technique in which mixed metal chloride solutions were added to different concentrations of boiling NaOH solutions to control particle growth rate. Thermomagnetization measurements indicated an increase in Néel temperature corresponding to increased particle growth rate and particle size. The Néel temperature is also found to increase inversely proportionally to the cation inversion parameter, delta, appearing in the formula (Mn(1-delta)Fe(delta))(tet)[Mn(delta)Fe(2-delta)](oct)O(4). These results contradict previously published reports of trends between Néel temperature and particle size, and demonstrate the dominance of cation inversion in determining the strength of superexchange interactions and subsequently Néel temperature in ferrite systems. The particle surface chemistry, structure, and magnetic spin configuration play secondary roles.
