Imprinting of Coordination Geometry in Ultrathin Films via the Surface Sol–Gel Process
摘要:
Imprinting of Cu2+ and Zn2+ ions was performed in ultrathin TiO2 films by the surface sol–gel process. The imprinted films showed stable and selective binding to template ions over the control metal ion. The selectivity is attributed to the immobilized geometry of ethylenediamine ligand.

An alcohol-based composition inhibited against high temperature aluminum cavitation erosion corrosion characterized by the presence of a polysilyl compound of the formula: ##STR1## wherein R is a substituted or unsubstituted organic radical; R.sup.1 is selected from the group consisting of hydrogen, monovalent hydrocarbon radicals and substituted monovalent hydrocarbon radicals; R.sup.2 is a monovalent moiety hydrolyzable to a hydroxyl group, each R.sup.2 being the same or different; a is an integer from 2 to 4, inclusive; b is an integer having a value of 0 or 1; n is an integer from 1 to 36, inclusive; and c is an integer having a value of 0 or 1; each ##STR2## group being the same or different, with the provisio that the compound have at least one ##STR3## group.
