basic information
**Lecture 1: Summary of the Presentation** Silica is widely used as an inexpensive inorganic material in various applications, including composites. In particular, it is the subject of active research as a representative inorganic component of organic-inorganic hybrid materials. Recently, there has also been vigorous research on hollow silica particles with nano-sized pores, leading to the development of hollow silica with various structures and forms. Hollow silica particles are attracting attention as new functional materials due to their unique functions and properties not found in conventional silica. This seminar will provide an easy-to-understand explanation of the representative synthesis methods for hollow particles centered around silica, such as the core-shell method and template method, as well as the synthesis, functions, properties, particle structure control, and applications of various hollow particles. **Lecture 3: Summary of the Presentation** This presentation will introduce methods for preparing silica particles with various nano-morphologies using amphiphilic molecules, represented by surfactants, as structural directing agents. First, it will cover the preparation methods and physical properties of nano-sized hollow silica particles utilizing vesicles, which are bilayer membrane structures, or air bubbles stabilized by surfactants. Next, it will introduce the preparation method of silica tubes using myelin figures, which are tubular molecular aggregates, as structural directing agents.
