Composite nanotubes formed by self-assembly of PbS nanoparticles
Leontidis, Epameinondas; Orphanou, M.; Kyprianidou-Leodidou, Tasoula; Krumeich, F.; Caseri, Walter (2003)Unusual arrangements of nanoparticles were observed during the synthesis and subsequent dissolution of PbS particles under the action of the surfactant sodium dodecyl sulfate (SDS) in solutions containing hydrophilic ...

Formation mechanism of nanotubes comprising layers of PbS nanoparticles in polymer-surfactant solutions
Orphanou, M.; Leontidis, Epameinondas; Kyprianidou-Leodidou, Tasoula; Caseri, Walter; Krumeich, F.; Kyriacou, Kyriacos C. (2006)The crystallization of PbS in aqueous solutions containing the surfactant sodium dodecyl sulfate (SDS) and hydrophilic polymers resulted in a novel type of metastable nanotubes, the walls of which consist of layers of ...

From beads-on-a-string to colloidal aggregation: novel crystallization phenomena in the PEO-SDS system
Leontidis, Epameinondas; Kyprianidou-Leodidou, Tasoula; Caseri, Walter; Kyriacou, Kyriacos C. (1999)The anionic surfactant sodium dodecyl sulfate (SDS) interacts strongly with poly(ethylene oxide) (PEO) in aqueous solution, forming micellar aggregates attached to the polymer chains above the so-called critical association ...

From colloidal aggregates to layered nanosized structures in polymer-surfactant systems. 1. Basic phenomena
Leontidis, Epameinondas; Kyprianidou-Leodidou, Tasoula; Caseri, Walter; Robyr, P.; Krumeich, F.; Kyriacou, Kyriacos C. (2001)In this work, we examine the rich crystallization behavior that occurs in PbII/S-II/poly(ethylene oxide) (PEO)/sodium dodecyl sulfate (SDS) systems, in which the anionic surfactant interacts strongly with the polymer ...

Surprising effects of polymer-surfactant solutions on inorganic crystallization processes
Leontidis, Epameinondas; Kyprianidou-Leodidou, Tasoula; Caseri, Walter; Kyriacou, Kyriacos C. (2001)Polymer-surfactant solutions, in which the surfactant molecules interact strongly with the polymer chains forming polymerbound micelles above the critical association concentration, are used as media for inorganic precipitation ...
