In the long human effort to impose order on nature's most restless matter, researchers at KAIST have found a way to coax gas molecules into crystalline arrangements inside porous materials — not through brute force, but through the quiet geometry of carefully designed pores. Led by Professor Jihan Kim, the team combined large-scale material screening with machine learning to identify structures capable of organizing gases like xenon into precise, repeating lattices. The discovery, announced in August 2026, suggests that the architecture of emptiness itself can become a tool — one with profound
