Shape‐Determined Kinetic Pathways in 2D Solid–Solid Phase Transitions

open access: yesAdvanced Science, Volume 13, Issue 4, 19 January 2026.
By simulating 2D ball‐stick pentagon, hexagon, and octagon systems, the kinetics of solid–solid phase transition is investigated, which is characterized by the loss of body‐orientation order. During which, the local defects of body‐orientation self‐organize into three different patterns, originated from the shape‐determined kinetic pathways, which may ...

Host Tuned Luminescence Lifetime Thermometers for Imaging Boiling Thermal Dynamics Through Bubbles

open access: yesAdvanced Optical Materials, Volume 13, Issue 36, December 19, 2025.
The bismuth to vanadate distance is adjusted in solid solutions of ytrrium and scandium orthovanadate to design a lifetime‐based luminescence thermometer with optimal temperature resolution at 100 °C. It is applied on the surface of a boiling channel to observe the thermal signatures of bubble growth and liquid film dry‐out.
