Anodizing 2

Bottom-Up approach
Category General
Difficulty Level Normal
Audience Level General
Description Top-down and bottom-up methods are two approaches used in nanofabrication. In this course, synthesis techniques which are known as bottom-up approach are presented.
Overview
Bottom-up approach means a view from bottom(smaller) to top or up(larger). In this technique, a nanometric structure is formed by using methods of assembly or self-assembly. For example: all cells use enzymes to create DNA by taking constituent molecules and binding them together to make the final component. Moreover, the bottom-up approach provides the possibility for creating hierarchical and ordered nanostructures because of physicochemical interactions and self-assembly of molecules.

Booklet
Description
 It starts with introducing aluminum anodizing as an electrochemical method. After a brief explanation it talks about pre-anodizing process. Then it talks about self-organized anodizing method. And, it goes through anodizing under a constant current density. It talks about anodizing under a constant potential. Then it ends with post-anodizing process.
Mental Challenge
 Does anodizing aluminum mean that aluminum is set as the anode and changes to nano?
