■ 演題： The Unfinished Science of Water Across Length Scales: From Clean Water to Microdroplets and Ice
■ 講師： Thalappil Pradeep 先生（IIT Madras）

Water continues to inspire new directions in science and technology. This lecture explores how fundamental insights
into water are enabling sustainable chemistry across length scales. First, nanomaterials developed for affordable
drinking-water purification will be introduced, including technologies that selectively remove contaminants such as
arsenic, iron, and uranium. The talk will then turn to charged water microdroplets as highly active chemical reactors.
Recent studies show that minerals such as quartz and ruby can disintegrate into nanoparticles within milliseconds
through electric fields, reactive species, and mechanical forces—an effect termed microdroplet mechanochemistry.
Finally, emerging insights into the physics and chemistry of ice will be discussed, highlighting the potential of water
interfaces, confinement, and ambient processes for sustainable materials synthesis and manufacturing.
