TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Method: The dominant constituent contains a mole-fraction majority of the fluid. During the subjecting step, the fluid's absolute temperature reaches at least halfway from the absolute temperature value at the triple point of the dominant constituent to the absolute temperature value at the critical point of the dominant constituent; or reaches at least 50, 90, 96% of, or goes above the absolute temperature value at the critical point of the dominant constituent; and the fluid's absolute pressure goes above the absolute pressure value at the critical point of the dominant constituent. The component is not simultaneously subjected to liquid and gaseous portions of the fluid during the subjecting step. The subjecting step entails placing the component in a vessel with the fluid being introduced into the vessel so that the fluid contacts the component. The method further includes separating the fluid and the component subsequent to the subjecting step. The separating step includes heating the component at a high vacuum or in another environment which is non-damaging to the component; and subjecting the component to actinic radiation preferably ultraviolet light and/or visible light. The dominant constituent is in the gaseous phase at an absolute pressure value of 1 atm and at 25degreesC.Preferred Flat-Panel Display: The flat-panel display is a flat-panel cathode-ray tube display.    TECHNOLOGY FOCUS - ELECTRONICS - Preferred Component: The component comprises an electron-emitting device or a light-emitting device.    TECHNOLOGY FOCUS - POLYMERS - Preferred Material: The organic material of the component is preferably polyimide comprising exposed photopolymerizable polyimide.Preferred Method: Part of the polyimide material enters the fluid during the subjecting step. It comprises low-to-medium molecular weight constituents of the polyimide material. At least a portion of it dissolves in the fluid during the subjecting step.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Constituent: The dominant constituent is carbon dioxide, ammonia, nitrous oxide, sulfur dioxide, or sulfur hexafluoride.Preferred Fluid: The fluid includes at least one additive for enhancing solvency.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Constituent: The dominant constituent is preferably butane, pentane, ethene, propene, butene, pentene, fluoromethane, difluoromethane, trifluoromethane, tetrafluoromethane, fluoroethane, difluoroethane, trifluoroethane, tetrafluoroethane, hexafluoroethane, fluoropropane, difluoropropane, hexafluoropropane, octafluoropropane, decafluorobutane, difluoroethene, fluoropropene, chloromethane, chloroethane, chlorofluoromethane, dichlorofluoromethane, chlorodifluoromethane, chlorotrifluoromethane, dichlorodifluoromethane, trichlorofluoromethane, chlorotrifluoroethane, chloropentafluoroethane, dichlorotetrafluoroethane, bromoethane, bromofluoromethane, bromotrifluoromethane, dibromodifluoromethane, iodotrifluoromethane, or at least one of their isomers.
