Anti‐Icing Organogel Enables Quasi‐Homogeneous Supercooling Preservation of Mouse Hearts

open access: yesAdvanced Science, EarlyView.
An organogel interface with a large energy barrier for ice nucleation is proposed to enable a quasi‐homogeneous supercooling preservation for organs. This method does not rely on cryoprotectant agents or machine perfusion and can double the ex vivo storage time of mouse hearts.

Atypical Hydrogen Bond Interaction Enables Anion‐Rich Solvation Structure in Polymer Electrolytes for High‐Voltage Flexible Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
A high‐voltage, Li‐metal‐compatible, and highly conductive polymer electrolyte is reported by integrating a low‐solvating fluorinated plasticizer. Strong atypical hydrogen bonds formed between the plasticizer and polymer chains promote the establishment of anion‐rich solvation structure, effectively stabilizing electrolyte‐electrode interphase at the ...
