Silver Nanoparticles with Controlled Dispersity and Their Assembly into Superstructures

ADVANCED ENGINEERING MATERIALS, Issue 5 2010
Karsten Moh
In this paper we report on the influence of particle size distribution, particle substrate interaction, and drying behavior on the self-assembly process using ligand stabilized silver particles. Two-dimensional particle arrays were characterized using transmission electron microscopy and extensive image analysis. The formation of such structures was observed in situ using an environmental scanning electron microscope in WET-STEM mode. The results confirm that a small particle size distribution is crucial for the formation of regular particle patterns with long range order, but also the particle substrate interaction and the particle density have an influence on the degree of ordering. Additionally, we find that separated binary particle assemblies keep the orientation of their two-dimensional hexagonal lattices over alternating domains of small and big particles. This is probably enabled due to the formation of dislocations and a small change of the course of the lattice lines within the respective boundary. [source]

Uniform Magnetic Chains of Hollow Cobalt Mesospheres from One-Pot Synthesis and Their Assembly in Solution,

ADVANCED FUNCTIONAL MATERIALS, Issue 3 2007
L. Guo
Abstract Magnetic chains up to 10,,m in length formed of hollow cobalt mesospheres (480,850,nm) with a 60,nm thick shell are synthesized by a new soft-assembly protocol. The obtained chains show a saturation magnetization of 37.5,emu,g,1, a remnant magnetization of 1.55,emu,g,1, and a coercivity of ca.,66,Oe at 300,K. A possible mechanism for the formation of the chainlike hollow structures is proposed. [source]

Semiconductor Nanorod Liquid Crystals and Their Assembly on a Substrate,

ADVANCED MATERIALS, Issue 5 2003
L.-S. Li
The macroscopic alignment and superlattice structures of CdSe nanorods in a nematic liquid-crystalline (LC) phase are determined by the phases that form prior to complete solvent evaporation (e.g., vortex structures in linear arrays, see Figure). By controlling the phase of the LC solution and its orientation using pretreated surfaces or external fields, it may be possible to achieve fine control of order in deposited nanorod films. [source]

Synthesis of Modular "Inorganic,Organic,Inorganic" Polyoxometalates and Their Assembly into Vesicles,

ANGEWANDTE CHEMIE, Issue 44 2009
Chullikkattil
Verknüpfte Cluster: Eine neue Klasse anorganisch-organisch-anorganischer Hybride mit Größen von etwa 3.4,nm wurde durch kovalente Funktionalisierung V3 -überdachter Wells-Dawson-Cluster mit linearen Bis(tris)-Liganden hergestellt (siehe Schema; TBA=nBu4N+) sowie röntgenkristallographisch und mit ESI-MS charakterisiert. Die Verbindungen weisen Tensideigenschaften auf (dynamische Lichtstreuung) und bilden in Lösung supramolekulare Vesikel. [source]
