Residual oxygen effect

Figure 14.17 also shows that in situ cleaning with EUV radiation in the presence of a residual amount of molecular oxygen is effective in restoring lost reflectivity. 

Plasma cleaning Dry process (no solvents or chemical solutions) active oxygen plasma is an aggressive cleaner for organic residues effective in removing adhesive bleedout Electron-free plasma is required to avoid damage to sensitive components cleaning surfaces with plasma prior to adhesive cure enhances bleedout... 

Alternatively to non-pressurized extraction the application of 0.6 MPa Oj pressure was investigated. These experimental conditions should generate an alkaline oxygen bleaching effect and lower the lignin content in both, the extracted xylan powder and the extraction residue. 

Water Treatment. Sodium sulfite is an agent in the reduction of chlorine or oxygen in water. Dissolved oxygen in boiler water tends to enhance pitting and other types of corrosion. In boilers operated at below 4.82 MPa (700 psi), a residual concentration of 30 ppm of sodium sulfite is generally effective. Catalytic amounts of cobalt are often added to accelerate the reaction of oxygen with sulfite (321,322) (see Water, industrial water treatment).
