Self‐Healing Ionogel Dual‐Network Enables Synergistic Defect Passivation and Strain Relief for High‐Efficiency Robust Perovskite Photovoltaics

open access: yesAdvanced Science, EarlyView.
PSCs are afflicted by inherent defects and lattice strain that limit PCE and stability. A cross‐linked multifunctional ionogel [HA‐AA][EMIES] is developed to modulate crystallization, relieve residual strain, and passivate defects, extending carrier diffusion length to over 8 µm and delivering PCEs of 26.45% for rigid devices and 25.14% for flexible ...

Pressure‐Activated and Retained Blue Emission in Melamine Through Hydrogen‐Bond and Packing Regulation

open access: yesAdvanced Science, EarlyView.
Pressure treatment activates and retains bright blue emission in melamine (MA). The pressure‐modified hydrogen‐bonding network and molecular packing create a distinct local environment after decompression, changing the balance among competing excited‐state relaxation pathways and enabling retained emission.

Assembled Hyaluronic Acid Therapeutics for Targeting M1 Macrophages and Regulating Immune Homeostasis for Ulcerative Colitis Treatment

open access: yesAdvanced Science, EarlyView.
An orally administered, drug‐free hyaluronic acid nanoassembly, uhNAs‐OA, accumulates in the inflamed colon and is preferentially internalized by M1‐like macrophages via HA‐CD44 interactions. uhNAs‐OA scavenges excess ROS, suppresses NF‐κB signaling and remodels the colonic immune landscape, resulting in robust therapeutic efficacy in acute, chronic ...

Nascent Extracellular Matrix Converts Biomaterial Cues into Cell Fate Decisions

open access: yesAdvanced Science, EarlyView.
This study uncovers a tri‐directional interplay among cells, hydrogels, and their nascent extracellular matrix. Hydrogel norbornene modification alters CD44‐mediated cell–hydrogel interactions, which shape nascent matrix deposition, composition, and spatial organization.
