Self-lubricating nanoparticles: self-organization into 3D-superlattices during a fast drying process.

چکیده
Fluorinated tetraethylene glycol-stabilized Au nanoparticles (FTEG-AuNPs) were well-dispersed in general polar organic solvents, such as methanol (MeOH) and THF. The cast film of FTEG-AuNPs on a TEM grid and a glass substrate was found to form a highly ordered 3D-superlattice assembly, whereas tetraethylene glycol-stabilized AuNPs (TEG-AuNPs) provide an amorphous AuNP aggregation. These data indicate that the fluorine feature on the surface of the FTEG-AuNPs is critical for the nanostructured assembly.

Tailoring the structure of nanocrystal superlattices is an important step toward controlled design of novel nanostructured materials and devices. We demonstrate how the long-range order and macroscopic dimensions of magnetic nanoparticle arrays can be controlled by the use of a modulated magnetic field. Inducing a dipolar attraction during the initial stage of the drying-mediated self-assembly ...

We demonstrate how the acquisition and processing of 3D electron diffraction data can be extended to characterize structural features on the mesoscale, and show how lattice distortions in superlattices of self-assembled spherical Pd nanoparticles can be quantified by three-dimensional small-angle electron diffraction tomography (3D SA-EDT). Transmission electron microscopy real space imaging an...
متن کاملTwo-dimensional gold trisoctahedron nanoparticle superlattice sheets: self-assembly, characterization and immunosensing applications.
Nanoparticles were called "artificial atoms" about two decades ago due to their ability to organize into regular lattices or supracrystals. Their self-assembly into free-standing, two-dimensional (2D) nanoparticle arrays enables the generation of 2D metamaterials for novel applications in sensing, nanophotonics and energy fields. However, their controlled fabrication is nontrivial due to the co...
متن کاملField Emission Scanning Electron Microscopy for Structural Characterization of 3D Gold Nanoparticle Superlattices
We prepared micrometer-sized three-dimensional (3D) superlattices of gold nanoparticles protected by Nacetylglutathione (NAG). The nanoparticles were self-assembled at an air/water interface under a highly acidic condition. Morphological studies revealed that the superlattices formed fivefold symmetric structures such as decahedron and icosahedron, which were probably developed by multiple twin...
