Formation of orientation-ordered superlattices of magnetite magnetic nanocrystals from shape-segregated self-assemblies.
Magnetic magnetite (Fe3O4) nanocrystals have been synthesized by combining nonhydrolytic reaction with seed-mediated growth. The shape of these magnetite nanocrystals can be controlled either as pure spheres or a mixture of mainly faceted nanocrystals. Faceted magnetite nanocrystals consist of truncated tetrahedral platelets (TTPs), truncated octahedrons (TOs), and octahedrons (OTs). Transmissi...
متن کاملTruncated hexa-octahedral magnetite crystals in ALH84001: presumptive biosignatures.
McKay et al. [(1996) Science 273, 924-930] suggested that carbonate globules in the meteorite ALH84001 contained the fossil remains of Martian microbes. We have characterized a subpopulation of magnetite (Fe(3)O(4)) crystals present in abundance within the Fe-rich rims of these carbonate globules. We find these Martian magnetites to be both chemically and physically identical to terrestrial, bi...
متن کاملCellulose nanocrystals: chemistry, self-assembly, and applications.
Cellulose constitutes the most abundant renewable polymer resource available today. As a chemical raw material, it is generally well-known that it has been used in the form of fibers or derivatives for nearly 150 years for a wide spectrum of products and materials in daily life. What has not been known until relatively recently is that when cellulose fibers are subjected to acid hydrolysis, the...
متن کاملControlled self-assembly of colloidal cobalt nanocrystals
Spherical cobalt particles are synthesized by injecting stock solution (0.54 g Co2(CO)8 dissolved in 3ml 1,2-dichlorobenzene) into refluxing 1,2-dichlorobenzene at 182 C in the presence of 0.2ml oleic acid and 0.1 g TOPO. Disks are prepared in a similar manner except 0.34 g linear amines are substituted for TOPO. We are developing a precipitation technique that is a variation of the solvent–non...
متن کاملSelf-Assembly of Luminescent Molecular Squares Featuring Octahedral Rhenium Corners.
The self-assembly of rigid inorganic cyclophanes comprising cis bridging metal centers connected by aromatic edges has emerged as a promising new area within the realm of hostguest chemistry.1-5 By utilizing the power and simplicity of molecular self-assembly which enables components to arrange themselves into square host cavities, chemists have synthesized a large number of new species with re...
