This event has concluded.
*This announcement is intended for university affiliates only.
The Institute for SDGs Promotion provides grants to support individual research, joint research with scholars inside and outside the university, and collaborative research with companies and other institutions. The purpose of the program is to identify research that will drive SDGs initiatives at the university and to revitalize research and educational activities that contribute to the Sustainable Development Goals (SDGs).
We are pleased to announce that the findings from the FY2024 SDGs Research Grants will be reported in a series of three sessions. We warmly welcome participation from students, faculty, and staff. Please feel free to share this information with colleagues on campus.
The first session will feature presentations by Professor Aya Tanatani (Faculty of Science) and Associate Professor Akira Chikamatsu (Faculty of Science). Each presenter will have approximately 20 minutes (allocated as 15 minutes for the report and 5 minutes for Q&A).
Date & Time: Wednesday, June 11, 1:20-2:50 P.M.
Venue: Inter-Faculty Building 1, Room 102 (In-person)
Presentations
Report 1: Application of novel vitamin D derivatives as rodenticides: To protect terrestrial ecosystems" (Prof. Aya Tanatani ; Department of Chemistry, Faculty of Science)

Report 1
Title: Application of novel vitamin D derivatives as rodenticides: To protect terrestrial ecosystems
Researchers:
・Aya Tanatani (Professor, Natural Science Division, Faculty of Core Research)
・ Hiroyuki Kagechika (Professor, Institute of Biomaterials and Bioengineering, Institute of Science Tokyo)
・ Satoshi Nagaoka (President, Daimaru Chemical Co., Ltd.)
Abstract: Rats cause immense damage to human society, including hygienic problems, disruption of urban functions, and economic loss. Rodenticides are effective for their extermination; however, the emergence of resistant rats and the poisoning of non-target organisms due to secondary toxicity are major issues, making the development of alternative agents an urgent task. We have created a novel lithocholic acid derivative, Dcha-20, which exhibits high vitamin D activity, and discovered that this compound possesses rodenticidal activity. This presentation will outline the structure and function of Dcha-20 and discuss its potential application as a rodenticide.
Report 2
Title: Development of cerium fluoride-based solid electrolytes for fluoride ion secondary batteries
Researchers: Akira Chikamatsu (Associate Professor, Natural Science Division, Faculty of Core Research)
Abstract: Lithium-ion secondary batteries are currently used in a wide range of devices, from smartphones to electric vehicles. However, due to the fire risks associated with lithium and geopolitical concerns, there is a demand for the development of all-solid-state secondary batteries using alternative elements. Recently, all-solid-state secondary batteries utilizing fluorine instead of lithium have attracted attention. Fluorine is far more abundant than lithium reserves, and fluorine-containing ores can be mined all over the world. Furthermore, all-solid-state secondary batteries using fluorine have high theoretical gravimetric and volumetric energy densities, enabling lighter and smaller batteries.
Thus, fluoride ion all-solid-state secondary batteries hold great potential for transforming industrial structures. However, many challenges remain for practical application, such as poor charge/discharge characteristics and high operating temperatures. Therefore, further basic research, including the search for new materials, is required. In this study, we focused on cerium fluoride as a solid electrolyte for fluoride ion all-solid-state secondary batteries and established a method for synthesizing single-crystal thin films of this material. This presentation will introduce the established synthesis method for cerium fluoride single-crystal thin films and report the results regarding the ion conductivity properties of the fabricated films.
