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 an introduction to chemical synthesis of materials. Then it explains the mechanism in detail, explains wet chemistry methods or coprecipitation methods. Then it talks about precipitation reactions, Redox reactions, hydrolysis, thermolysis, polymerization, and condensation. It ends with a brief conclusion.
Mental Challenge
 Why do we call it “Liquid-Phase Precipitation”?
Quizzes and Activities
 Activity: Compare different liquid-phase precipitation methods in a chart.
