    Abstract: A method and related apparatus to link and/or pattern self-assembled first objects to a second object. Each of the first object (e.g., a nanoparticle) can be embedded in a mobile binder (i.e., a stabilizer). The invention applies energy to the first object and stabilizer, links this first object to the second object, and provides a controlled linkage of the first object with respect to the second object. Applying this procedure to many such objects results in a larger a real arrangement of these linked objects. An appropriate solvent may be used to remove non-linked objects, yielding a patterned array. Thermal annealing can be applied to control the physical and chemical properties of the array.

    Abstract: A method and structure for making magnetite nanoparticle materials by mixing iron salt with alcohol, carboxylic acid and amine in an organic solvent and heating the mixture to 200-360° C. is described. The size of the particles can be controlled either by changing the iron salt to acid/amine ratio or by coating small nanoparticles with more iron oxide. Magnetite nanoparticles in the size ranging from 2 nm to 20 nm with a narrow size distribution are obtained with the invention. The invention can be readily extended to other iron oxide based nanoparticle materials, including M Fe2O4 (M=Co, Ni, Cu, Zn, Cr, Ti, Ba, Mg) nanomaterials, and iron oxide coated nanoparticle materials. The invention also leads to the synthesis of iron sulfide based nanoparticle materials by replacing alcohol with thiol in the reaction mixture. The magnetite nanoparticles can be oxidized to γ-Fe2O3, or α-Fe2O3, or can be reduced to bcc-Fe nanoparticles, while iron oxide based materials can be used to make binary iron based metallic nanoparticles, such as CoFe, NiFe, and FeCoSmx nanoparticles.
