Nevertheless, atomic layer deposition (ALD) can be proposed as a new attractive alternative.
The use of ALD to improve the corrosion protection of metals has been under intensive study in the past few years.(14-17) In this study, a coating was formed by a first [AI.sub.2][O.sub.3] layer, and a secondary [TiO.sub.2] coating was applied with the aim of using the [AI.sub.2][O.sub.3] as an adhesion promoter and a highly resistive layer(18) and protecting its chemical integrity using the high stability and low wettability(19) of the amorphous [TiO.sub.2] second layer.
Square 10 X 10 cm samples were then obtained and were used for ALD and surface characterization.
The ALD coating was deposited by Beneq Oy (Finland) using a TFS 500 instrument.

ALD's three websites are managed by the coordinator/supervisor of web services--the position that the author holds--and staffed by two and a half internet librarians.
The internet librarians are responsible for daily posting to their respective Facebook pages (Arapahoe Library District, Arapahoe Library District (ALD)-Teens, and Arapahoe Library District-Children's Services) and regularly to their Twitter (ArapahoeLibrary, ALD_Teens, and ALDstorytime) accounts.
In addition, regular checks are carried out for user posts about ALD through Google Alerts.
