Coated nanowires comprising a core and a ferromagnetic coating are magnetically aligned and bound to a substrate. The substrate may have a thiol-functionalized surface. In some examples, the coated nanowires are nickel-coated copper nanowires and the substrate may be a carbon-doped oxide or silicon oxide.

Nanowires with magnetic coatings and methods for making and using

Formulations for stabilizing hydrogen peroxide, comprising water soluble Znions at 0.7 to 100 parts per million of an alkaline hydrogen peroxide solution. In some examples, the alkaline hydrogen peroxide solution is a silicon wafer cleaning solution comprised of HOand NHOH&#x2014;HO and the water soluble Znions are present at 3 to 100 parts per million of the silicon wafer cleaning solution. In some examples, the alkaline hydrogen peroxide solution is a wet etching formulation selective for TiN and the water soluble Znions are present at 0.7 to 10 parts per million of the wet etching formulation. In some examples, the alkaline hydrogen peroxide solution is a wet etching formulation selective for Ti and Zn ions are present at 2 to 7 parts per million.

Stabilized alkaline hydrogen peroxide formulations

Sub-50-nm structures are formed using sequential top-down and bottom up lithographies in conjunction with selective etching. The preferred rendition of the method involves: (a) rough lithographic patterning, (b) size/shape selected nanostructure deposition, (c) resist reflow around the nanostructures, and (d) selective removal/etching of the nanostructure.
