Do all parts of a liquid freeze at the same rate? This review explores the phenomenon of spatially heterogeneous dynamics in supercooled liquids, where some regions exhibit dynamics orders of magnitude faster than others just nanometers away. The experimental work characterizing this heterogeneity is described, addressing questions about the size, duration, and dynamic variations within these liquids. It dives into the questions: How large are these heterogeneities? How long do they last? How much do dynamics vary between the fastest and slowest regions? Why do these heterogeneities arise? Spatially heterogeneous dynamics in supercooled liquids describes the experimental work that characterizes this heterogeneity. The answers to these questions have practical implications for the application of glass-forming materials, including polymers, metallic glasses, and pharmaceuticals. The review provides a comprehensive overview of this fascinating area, fostering further research and innovation in materials science. In particular, the answers to these questions influence practical applications of glass-forming materials, including polymers, metallic glasses, and pharmaceuticals.
Published in the Annual Review of Physical Chemistry, this review aligns with the journal's focus on providing comprehensive overviews of key topics in physical chemistry. The examination of spatially heterogeneous dynamics in supercooled liquids is highly relevant to the journal's scope, contributing to a broader understanding of liquid behavior and materials science.
