Direct ink writing of osteoconductive scaffolds using a crosslinked collagen–hydroxyapatite ink

Biofabrication
Abstract Large bone defects present a major clinical challenge, exceeding the body’s natural regenerative capacity. In this study, we investigated the physicochemical and biological properties of a novel cross-linked collagen–hydroxyapatite (Coll-HA-XL) biomaterial ink designed for additive manufacturing of scaffolds for bone tissue ...

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
