Porous Materials Chemistry Lab
Machine-translated · View original
A lab that creates porous materials in which tiny pores are built exactly as designed.
AboutAbout the lab
Designing the size and shape of pores, and making them.
The Hasegawa Lab researches porous materials with many tiny pores, made using the sol–gel method, which creates materials from solutions.
Pore size, shape, and void fraction vary by material. The lab tailors these to the intended purpose and works to develop new materials with excellent performance.
It also works on applying the materials it makes to environmental and energy fields, such as catalysis and electrochemistry.
The lab was newly established as the Hasegawa Lab in April 2026.
Key terms
- Sol–gel method
- A method of making materials by reacting a source solution to form a liquid with fine particles dispersed in it (a sol), then solidifying it into a network (a gel)
- Aerogel
- An extremely lightweight solid that is mostly empty space. It conducts heat poorly
- All-solid-state secondary battery
- A rechargeable battery that uses a nonflammable solid electrolyte instead of a flammable liquid electrolyte

ResearchResearch themes
The lab focuses on fabricating porous ceramic materials useful in separation, adsorption, catalysis, and energy, and on controlling their fine structure. In particular, it aims to establish techniques for creating “hierarchical porous structures”, which combine pores of different sizes, such as nanometer-scale and micrometer-scale pores, each with a uniform size.
*Illustrative imageUsing phase separation to make materials with uniform pores
The structure formed as components separate during the sol–gel reaction is fixed as it is inside the gel, producing a porous monolith. This works for various materials such as organic polymers and silica, and when combined with other methods it can also create structures with pores of different sizes. The lab aims at applications in separation, adsorption, catalysis, and electrodes.
*Illustrative imageThermal insulation with aerogel, a material full of voids
Aerogels conduct heat poorly and are expected to serve as thermal insulation, but their high production cost and fragility are challenges. The lab addresses these challenges through industry–academia collaboration toward practical use.
*Illustrative imageMaterials for all-solid-state secondary batteries
Toward all-solid-state secondary batteries, which replace flammable liquid electrolytes with nonflammable solid electrolytes, the lab studies how ions move through solids. By carefully fabricating materials, it examines reactions at the interface between the solid electrolyte and the electrode.
