A method for extending the useful and economic life of an aircraft and improving aircraft efficiency is provided. This method produces significant fuel savings on the ground and in flight as well as cost-effective and efficient operation of and reduced maintenance requirements for older aircraft. The increased economic viability of the continued use of older aircraft is achieved by equipping an aircraft with at least one onboard drive wheel assembly controllably powered to drive the aircraft during ground travel independently of aircraft engines or external tow vehicles. The substantial elimination of damage to an aircraft's airframe, brakes, landing gear, and engine components resulting from tow vehicle attachment, brake application during ground travel with operating aircraft engines, or by FOD produces cleaner, more efficient engine operation during flight. Significant and substantial potential cost savings realized by the present method makes the continued use of older aircraft a viable option.

An electroless etching process. The process produces nanostructured semiconductors in which an oxidant (Ox1) is deposited as a metal on a semiconductor surface and used as a catalytic agent to facilitate reaction between a semiconductor and a second oxidant (Ox2). Ox2 is used to initiate etching by injecting holes into the semiconductor valence band as facilitated by the catalytic action of the deposited metal. The extent of reaction is controlled by the amount of Ox2 added; the reaction rate is controlled by the injection rate of Ox2. The process produces high specific surface area and / or hierarchically structured porous Si with higher and controllable yield. In addition, the ability is demonstrated to vary the pore size distribution of mesoporous silicon including producing hierarchically structured mesoporous silicon with more than one peak in the pore size distribution. In principle, the process applies to any semiconductor onto which metal can be deposited galvanically.
