Room-temperature serrated-flow behavior in Fe-rich FeAl under vacancy supersaturation [PDF]
, 1998 In Fe-rich FeAl, serrated plastic-flow behavior has been observed for the first time at room temperature. Serration on the tensile stress-strain curve occurs in single crystals that retained supersaturation of thermal vacancies after fast-cooling from ...

1T‐to‐2H Phase Evolution During Epitaxial Growth of Transition Metal Dichalcogenides
Advanced Materials, EarlyView.During MOCVD growth of MoS2 and WSe2, a transient metallic 1T phase emerges in early, edge‐rich, chalcogen‐deficient domains and declines as the films ultimately coalesce as 2H material. Together, experiments and ReaxFF simulations link domain size, edge stoichiometry, and vacancies to this evolution.

Advanced Materials, EarlyView.In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.
