Solid but fluid: New materials reconfigure their entire crystal structure in response to humidity
NEW YORK, March 11, 2026 — Most solid materials we rely on, from steel, to plastics and ceramics, are designed to have specific properties. Whether a material is soft and flexible, or stiff and tough depends on how molecules within the material are organized. That stability is useful, but it comes at a cost: once made, these materials' properties are fixed, and they rarely adapt to their environment.
A new study published in the journal Matter (Cell Press) and led by researchers at the Advanced Science Research Center (ASRC) at the CUNY Graduate Center challenges that assumption, demonstrating solid materials that can reversibly reorganize their internal structure and dramatically ...
