山下誠司教授の研究室では、高温環境下でも安定した性能を発揮するセラミックス複合材料の開発と、その応用に向けた摩擦・潤滑特性の解明を主な研究テーマとしています。特に炭化ケイ素（SiC）を基体にしたボロンカーバイド（B₄C）複合材料の表面反応や自己潤滑挙動に注目し、高温処理による物性変化を解明しています。また、産業廃熱回収や集中太陽光発電向けの高効率熱蓄熱材料の開発も進め、ナノ構造のマクロカプセル技術を応用した新規材料の創出を目指しています。

Abstract A B 4 C‐SiC composite without annealing and two B 4 C‐SiC composites followed by annealing at 1000℃ and 1200℃ for 1 hour in air, respectively, were prepared. The tribological properties of the three composites were evaluated by sliding against SiC balls at room temperature under unlubricated conditions. The B 4 C‐SiC composite can obtain lower friction coefficient by annealing at 1000℃, whereas the friction coefficient of B 4 C‐SiC composite annealed at 1200℃ was significantly increased
This paper describes construction and experiments of the WYSIWYAS M-CubITS pedestrian navigation system. Taking pictures of M-CubITS elements on the floor, positioning of the camera is carried out by image processing. HMI is based on WYSIWYAS. It is confirmed that this navigation system works.
Developing thermal storage materials is crucial for the efficient recovery of thermal energy. Salt-based phase-change materials have been widely studied. Despite their high thermal storage density and low cost, they still face issues such as low thermal conductivity and easy leaks. Therefore, a new type of NaCl-Al2O3@SiC@Al2O3 macrocapsule was developed to address these drawbacks, and it exhibited excellent rapid heat storage and release capabilities and was extremely stable, significantly reduc
