We are pleased to introduce a video produced and released by the SCIENCE CHANNEL in April 2025, highlighting the research of Distinguished Professor Katsuya Teshima from the Research Initiative for Supra-Materials (AQUA-Regeneration) at Shinshu University. His groundbreaking work focuses on "Mg-Al layered double hydroxides," a crystalline material designed to remove fluoride ions from groundwater in Tanzania and transform it into safe drinking water.
