Which synthesis method will not work for growing metal nanowires. (you can use a process of elimination to figure this out)(a) catalyst based growth: involves the use of a metal to facilitate the decomposition of a gas containing the constituent element(s), concentration of those elements in the molten catalyst and precipitation out as a nanowire.(b) anisotropic growth: most materials have different growth rates on different crystal faces. this can be exploited to create nanowires by way of optimizing conditions to cause a nanoparticle to grow more along one axis compared to the other directions.(c) nanopore template growth: electroplating within the confines of a cylindrical pore in a polymer or alumina film having a diameter in the nm range. the electroplated metal takes on the shape of the pore as it fills it. dissolution of the film releases the nanowires.(d) liftoff using standard vlsi techniques: similar to the template method for growing, this process uses a sacrificial layer to define the geometry of material deposited onto a substrate. one key difference is that this method allows for nanowires that are parallel to the surface to be made.
