4 Οκτ 2023 · In the first chapter, we explain the definition of colloids and describe the significance of self-assembly and structure formation of colloids. We then explain the relationship between colloid science and various other scientific and technological fields. An overview of this book will also be given.
Describe the composition and properties of colloidal dispersions. List and explain several technological applications of colloids. As a child, you may have made suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water, known as tempera paint.
