Destruction NoticeDestroy this report when it is no longer needed. "itThe UV/ozone method, which is reviewed in this repo-Tt, is anefective method of removing a vat jety of contaminants from surfaces. It is a simlple-to-use dry process which is inexpensive to set up and operate. It can rapidly produce clean surfaces, in air 3r in a I vacuum systemn, at ambient temperatures. Placing properly precleaned surfaces wilhin a few millimeters of an ozonIe-producing UV Source can produce clean surfaces in less than one mlinute.

Annealing of SnO_2 thin films by ultra-short laser pulses

“…The concentration reduces with increasing laser fluence (see Table 1 and Fig. 6), similarly to elsewhere reported [23]. Since the TOF-SIMS analysis shows only counts, XPS was adopted to obtain an absolute value of the carbon concentration.…”

The Effects of Ion Implantation on the Tribology of Perfluoropolyether-Lubricated 440C Stainless Steel Couples

“…The pair was then blown dry with nitrogen and promptly covered to minimize dust contamination. Following this, the pair was UV/ozone treated for 15minutes to remove carbonaceous contamination (24). Discs that did not have PFPE applied to them, and all bearing balls were put into a dry N2atmosphere within 5 minutes of the UV/ozone treatment where they stayed until tribo-tested.…”

Effect of ultraviolet light irradiation period on bond strengths between fiber-reinforced composite post and core build-up composite resin

“…It has been suggested that UV irradiation cleans the polymer surface by removing the organic contamination and changing the molecule structure of the matrix polymer [15][16][17][18][19][20] , which modifies the surface tension. However, the wetting tension values of the matrix resins did not greatly change after irradiation.…”

“…The silane coupling treatment can establish chemical bonding between the fiberglass of the FRC post and the core build-up materials. Plasma and UV irradiation are considered to clean surfaces by removing the organic contamination 11,15,16) , increasing the surface microroughness [16][17][18][19] , and changing the molecular structure of the surface area [16][17][18][19][20] . If the molecular structure of the matrix resin is changed, it is possible to create IPN bonding despite the thermoplastic polymers.…”
