Ordered alignment of CdS nanocrystals on MWCNTs without surface modification

Article Abstract:

A facile hydrothermal procedure capable of aligning CdS nanocrystals on multiwalled carbon nanotubes (MWCNTs) without the use of organic bridging molecules such as cysteamine and carboxylates is described. The particle size of CdS on the MWCNTs could not be easily controlled, the surface coverage, the crystal phases, and the orientation could be altered by manipulating the reaction time and by selecting the appropriate chelating agent.

A phase-transfer identification of core-shell structures in Ag-Pt nanoparticles

Article Abstract:

A simple phase-transfer protocol that can uniquely identify core-shell Ag-Pt nanoparticles prepared by the seed-mediated growth method is presented. It was found that core-shell Ag-Pt nanoparticles could be obtained by the seed-mediated growth method using Ag nanoparticles as the seeds.

Core-shell Ag-Au nanoparticles from replacement reaction in organic medium

Article Abstract:

The replacement reaction between hydrophobized Ag nanoparticles and hydrophobized AuCl4- in toluene are examined in detail. Solvent and temperature are influential environmental factors that determine the structure and composition of nanoparticles formed by the replacement reaction.
