METALLIC NANOWIRES AND METHODS THEREOF
Aspects relate to method of zinc-comprising nanowire fabrication, the method comprising forming a starting material comprising zinc metal or zinc metal alloy and at least one reactive metal, and exposing the starting material to one or more alcohols to obtain a reaction product comprising zinc-comprising nanowires, wherein the at least one reactive metal is more reactive than zinc to the one or more alcohols.
System and method for precision transport, positioning, and assembling of longitudinal nano-structures
A method for assembling multi-component nano-structures that includes dispersing a plurality of nano-structures in a fluid medium, and applying an electric field having an alternating current (AC) component and a direct current (DC) component to the fluid medium containing the plurality of nano-structures. The electric field causes a first nano-structure from the plurality of nano-structures to move to a predetermined position and orientation relative to a second nano-structure of the plurality of nano-structures such that the first and second nano-structures assemble into a multi-component nano-structure.

Method for producing metal nanowire
A method for producing metal nanowire of small diameter and long length. In the method for producing a metal nanowire, a first solution containing an ionic derivative and a polyol as a solvent are kept at 80-200° C., and a second solution containing a metal salt and a polyol as a solvent is supplied into the first solution so that the ratio between the number of moles of metal atoms in the metal salt supplied in one minute and the total number of moles of halogen atoms in the ionic derivative in the first solution (the number of moles of metal atoms in the metal salt supplied in one minute/the total number of moles of halogen atoms in the ionic derivative) is less than 10. It is preferable that the ionic derivative is a quaternary ammonium halide and the metal salt is silver nitrate.
High Conductivity Magnesium Alloy
A castable, moldable, or extrudable magnesium-based alloy that includes one or more insoluble additives. The insoluble additives can be used to enhance the mechanical properties of the structure, such as ductility and/or tensile strength. The final structure can be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final structure as compared to the non-enhanced structure. The magnesium-based composite has improved thermal and mechanical properties by the modification of grain boundary properties through the addition of insoluble nanoparticles to the magnesium alloys. The magnesium-based composite can have a thermal conductivity that is greater than 180 W/m−K, and/or ductility exceeding 15-20% elongation to failure.
