Near‐Infrared Circularly Polarized Electroluminescence with Switchable Handedness in Organic LEDs

open access: yesAdvanced Functional Materials, EarlyView.
The first fully‐organic circularly polarized near‐infrared OLED, using a co‐assembled active layer of ITIC and a chiral inducer, exhibits dissymmetry values up to 0.074 and 1.65 Wsr−1m−2 radiance. The circular polarization sign can be switched by manipulating the position of the recombination zone, resulting in enhanced device performance and stability.

Gd‐Induced Oxygen Vacancy Creation Activates Lattice Oxygen Oxidation for Water Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
DFT calculations shows that Gd incorporation into Fe‐doped NiO raises the O 2p band center, lowers oxygen vacancy formation energy, and thus promotes the LOM mechanism for OER. Gd and Fe co‐doped NiO nanosheets synthesized via spray combustion exhibits a low overpotential of 227 mV and maintains stable AEMWE performance for over 120 h, demonstrating ...

Electrolyte Engineering Strategy with Catecholate Type Additive Enabled Ultradurable Zn Anode

open access: yesAdvanced Functional Materials, EarlyView.
A catecholate‐type molecule is proposed as a multifunctional electrolyte additive, providing a strong buffering ability as well as homogeneous (101)‐textured electroplating morphology. The modified Zn anode exhibits a remarkable rate capability, extraordinary reversibility, and superior cyclic stability.

Immune‐Infiltrated Cancer Spheroid Model with Vascular Recirculation Reveals Temporally Dependent and Tissue‐Specific Macrophage Recruitment

open access: yesAdvanced Healthcare Materials, EarlyView.
The migration and infiltration of circulating monocytes into cancer spheroids are shown using a pumpless recirculating platform. This method allows for the continuous circulation of immune cells, which is essential for observing the long‐term dynamic behavior of immune cells within cancer environments.

Engineered In Vitro Multi‐Cell Type Ventricle Model Generates Long‐Term Pulsatile Flow and Modulates Cardiac Output in Response to Cardioactive Drugs

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents an innovative in vitro model of a human left ventricle using biofunctionalized PDMS membranes and human iPSC‐derived cardiomyocytes. The engineered ventricle demonstrates stable, long‐term pulsatile flow, and physiological responses to cardioactive drugs.
