Nanostructure formation in polyelectrolyte-surfactant complexes

Article Abstract:

Pronounced nanostructure formation with periodicity of about two or four times the surfactant molecule length was observed in all gel-surfactant complexes whose phase transition to the collapsed state in slightly cross-linked positively charged gels of poly(diallyldimethylammonium chloride) interacting with n-alkyl sulfates was investigated. Data from an experiment with anionic linear polyelectrolyte-cationic surfactant showed that the formation of crystalline polyelectolyte-surfactant complexes is not confined to the cationic gel-anionic surfactant mixtures.

Novel silver nanostructures from silver mirror reaction on reactive substrates

Article Abstract:

Novel silver clusters are prepared by simply carrying out the silver mirror reaction on certain reactive substrates. Leaflike fractal silver microstructures and perpendicularly aligned silver nanosheets are produced on a commercially available copper foil and sandpaper-rubbed copper foil.

A new and simple means for self-assembled nanostructure: Facilitated by buffer layer

Article Abstract:

A new and simple means of growing ZnO nanowire (NW) arrays using a TiN buffer layer is proposed although the crystal structure obtained differed entirely from that of ZnO. One-dimensional semiconductor nanomaterials are expected to be important components in nanodevices.
