The Reason of Changing Properties in Nano Scale

Materials & Properties
Category General
Difficulty Level Normal
Audience Level General
Description Materials and their components are described in this course. In addition, Materials’ classification and different kinds of properties are explained. Which properties are changed in nanoscale and the reason of these changes are another subject which are considered in this course.
Overview
In this course, materials and their components are introduced. Components lead to classify materials in different groups. Every group has its specific structure and properties. All of these subjects are explained in this course. Furthermore, in nanoscale, properties are changed. The reason of outstanding material properties in nanoscale is also explained in this course.
 
It should be noted, if material properties are introduced in bulk and nanoscale taking a deductive approach, tangible concepts of structures in nanoscale are gained. Deductive approach enables us to classify nano and bulk materials in our mind.


Booklet
Description
 Material properties change in nanoscale compared to their bulk state. Properties, such as electrical conductivity, color, light emission, mechanical strength, and other types of properties are all changed by entering nanoscale. Quantum and surface effects are two important facts that change the behavior of nanomaterials compared to the bulk materials.
Mental Challenge
 Why do not wire or components of a nanoscale circuit necessarily follow Ohm's law? 
Quizzes and Activities
 Activity: With your magnetic stick and balls, make a bulk structure and compare numbers of connections of surface balls and connections of inside ones. Which one is harder to take out from structure?
