Valence and Site Engineering Enable Efficient Broadband Near‐Infrared Emission at 960 nm in Cr3+‐Activated Forsterite

Advanced Materials, EarlyView.
This study reports a near‐infrared (NIR) luminescent material (Mg2SiO4:1.5%Cr,5%Li) with efficient (EQE = 48%) ultra‐broadband (FWHM ≈ 2413 cm−1 (226 nm)) NIR emission at 960 nm upon blue‐light excitation. This innovation addresses the low efficiency of long‐wavelength (λmax > 900 nm) NIR‐emitting materials due to the radiationless de‐activation and ...

One‐Step Coordinated Multi‐Kinetic 4D Printing of Human Vascularized Cardiac Tissues with Selective Fast‐Shrinking Capillaries

Advanced Materials, EarlyView.
This study presents a novel 4D bioprinting technique for fabricating cardiac tissues with complex microvasculature. Unlike traditional 3D printing, it enables capillary‐scale structure formation via selective post‐printing shrinkage. This approach overcomes resolution limits of printing cell‐laden hydrogels, allowing the creation of functional ...

A Smart and Highly Porous Hydrogel for Diabetic Wound Healing

Advanced Materials Interfaces, EarlyView.
A novel hydrogel comprising a dual‐crosslinked network of Poly(N‐isopropylacrylamide) (PNIPAM) and Gum Arabic (GA) with superior mechanical and anti‐inflammatory properties is designed for advanced diabetic wound healing. Abstract Conventional hydrogels often suffer from poor mechanical strength, limited bioactivity, and uncontrolled therapeutic ...

Orientation Control in Epitaxial PdO Thin Films Grown on MgO (001) – Role of Oxygen Chemical Potential

Advanced Materials Interfaces, EarlyView.
Crystal orientation of thin films is closely linked to their strain states, electronic properties, and surface chemical reactivity of functional materials. Therefore, understanding the mechanisms that govern orientation control is essential for materials design and synthesis.
