The invention provides methods for producing hydrogen and oxygen, comprising the steps of: oxidising a mediator at a working electrode to yield an oxidised mediator, and reducing protons at a counter electrode to yield hydrogen; and reducing an oxidised mediator at a working electrode to yield a mediator, and oxidising water at a counter electrode to yield oxygen. Embodiments include EUV lithography tools provided with at least one hydrocarbon getter comprising a substrate and a high energy source, such as an electron gun or separate EUV source, positioned to direct an energy beam, having sufficient energy to crack heavy hydrocarbons and form carbon, on the substrate. The instructions can include instructions to access a surface definition file from a library of surface definition files at the computing device based on the indicator of the surface type, and define, based on the parameter value characterizing the interaction and based on the surface definition file, a movement instruction configured to trigger a movement in the drawing device. The front-end processor may have multiple signal feeding and signal extraction points, other than the two ends, to which connections can be made to feed signals into and extract signals from the front-end processor. 5, wherein the black colorant-containing PTFE nanofiber is obtained by subjecting a spinning solution containing at least PTFE or modified PTFE to an electrospinning method. Preferably, the power cable is a medium or high voltage power cable, and the polyolefin is crosslinked as the sheath layer is fabricated andor subsequent to the fabrication of the sheath layer.
