Description Top-down and bottom-up methods are two types of approaches used in nanofabrication. In this course, synthesis techniques which are known as top-down approach are presented.
Overview
Top-down approach means a view from top(larger) to bottom(smaller). This approach is similar to making a statue made of stone. As in making of a statue, a bulk or big piece of stone is taken, similarly in top-down approach; a bulk piece of material is taken. Then carving and cutting is done until desired shape is achieved. Example: Different kinds of lithographic techniques include cutting, etching, grinding and ball milling technique.
In this course, top-down approach is taken into consideration. By the end of this course, students would be able to choose the right technique to achieve desired nanomaterial.

Booklet
Description
It starts with concepts (stress,…), talks about different types of deformation, plastic deformation, how it makes nano, and its properties. It ends with types of severe plastic deformation.

Mental Challenge
How severe should plastic deformation be in order to synthesize nano?
