Quantum-size colloid metal systems

Surface modification of ferromagnetics for polymer composites

“…The sample of ultradispersed powdered Ni synthesized by the plasma evaporation of a metal with the subsequent condensation of particles in the inert gaseous mixture [8] was used as an object for this study. The X-ray powder diffraction (XRD) pattern of synthetic Ni (Fig.…”

Nonlinear optical studies of lead lanthanum borate glass doped with Au nanoparticles

“…Au nanoparticles larger than 2 nm typically have a plasmon band in the range of 500-550 nm [34,35]. However, when the particle size is less than 2 nm, the distinctive plasmon band is replaced by a featureless absorbance, which increases monotonically toward higher energies [36,37].…”

Methylviologen mediated electrochemical reduction of AgCl—A new route to produce a silica core/Ag shell nanocomposite material in solution

“…The keen interest in these objects is due to the wide variety of their potential applications in catalytic, biomedical, optical, electronic and other fields [1][2][3][4][5][6][7]. The methods of preparation of metal nanoparticles are quite diverse.…”
