This chapter includes mechanical properties,thermal properties,magnetic properties,electric materials.Help students master the basic knowledge and or understand physical phenomenon in nanoscale 2.Key and difficult points in Teaching mechanical properties,thermal properties,magnetic properties,electric properties and optical properties of nanc naterials 3.Teaching contents 1)Mechanical properties of Nanomaterials. This section introduces the definitions of stress,strain and dislocation.The Hall-Petch Relationship and Inverse Hall-Petch Relationship will also be studied.The relationship between the stress and strain that a particular material displays is known as that particular material's stress-strain curve 2)Thermal properties of Nanomaterials This section introduces the size dependent melting temperature,specific heat and thermal conductivity.When the size of the particles is small enough,the melting temperature specific heat and thermal conductivity may be greatly changed. 3)Magnetic properties of Nanomaterials. This section introduces the concepts of ferromagentism,magnetic domain and magnetic hysteresis loop:Phenomenons of super-paramagnetism,size dependent magnetic domain and hysteresis loop will also be studied. 4)Electrical and optical properties of Nanomaterials. This section inroduces the concepts of energy band,band gap,the Size dependen conductivity (IV curve)and Coulomb blockade.The Concepts of surface plasma,light adsorption and emission will asbe studied. 4.Teaching Methods Teachers teach,teachers and students discuss,and guide studentssef-eain 5.Teaching Evaluation Corresponding exercises after class,supplementary exercises,thinking questions,et Chapter 4 Synthesis Techniques for Nanomaterials 1.Course objective This chapter includes concept of top-dowr and botto om-up methods for preparation of nanoparticles.Help students master the basic knowledge and basic physical experimental methods related to nanomaterial synthesis 2.Key and difficult points in Teaching This chapter includes mechanical properties, thermal properties, magnetic properties, electric properties and optical properties of nanomaterials.

Teaching contents 1) Mechanical properties of Nanomaterials. This section introduces the definitions of stress, strain and dislocation. The Hall-Petch Relationship and Inverse Hall-Petch Relationship will also be studied. The relationship between the stress and strain that a particular material displays is known as that particular material's stress–strain curve. 2) Thermal properties of Nanomaterials. This section introduces the size dependent melting temperature, specific heat and thermal conductivity. When the size of the particles is small enough, the melting temperature, specific heat and thermal conductivity may be greatly changed. 3) Magnetic properties of Nanomaterials.
