Nanoparticle‐Mediated Bubble Suppression During Droplet Solidification for Mechanical Reinforcement

open access: yesAdvanced Science, EarlyView.
Nanoparticles mediate droplet solidification by raising nucleation temperature, refining dendrites, and slowing freezing‐front advance, thereby suppressing trapped air bubbles in droplet‐based 3D printing. This strategy reduces bubble volume fraction by ∼35% and increases compressive strength by up to 39%, offering a low‐cost route to stronger printed ...

Synergistic Additive and Bulky Cation Engineering via a Sequential Vacuum Dry‐Dipping Process for Tin Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
A spin‐coating‐free sequential blade–dipping process is developed for efficient tin perovskite solar cells. Amorphous SnI2 templates are blade‐coated and vacuum‐dried, followed by a vertical dipping conversion. Enhanced by a synergistic additive matrix and bifunctional BATo cation, the resulting devices achieve a benchmark power conversion efficiency ...

Lithium‐Ion Battery Safety Evaluation by Quantifying Lithium Plating Degree Based on Pressure Signals

open access: yesAdvanced Science, EarlyView.
Low N/P cells enable controllable lithium plating, allowing the lithium plating degree (DLi) to be quantified and linked to thermal safety. Pressure signals during calibration provide a non‐destructive route to diagnose DLi, while thermal response tests define safety levels and management strategies. The framework remains applicable in commercial 12 Ah
