A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

Advanced Healthcare Materials, EarlyView.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

A resonant switched-capacitor converter for voltage balancing of series-connected capacitors

A resonant switched-capacitor converter for voltage balancing of series-connected capacitors
This paper describes a resonant switched-capacitor converter (RSCC) for voltage balancing of several capacitor or battery modules connected in series. This voltage balancing circuit transfers electric charge between the capacitor modules with a soft switching operation, resulting in a reduction of power loss and EMI.

Shellac‐Mediated Assembly of Nanoparticles for mRNA Delivery

Advanced Healthcare Materials, EarlyView.
A shellac‐mediated nanoparticle assembly strategy is presented, involving the complexation of mRNA and low‐molecular‐weight cationic molecules (e.g., polyethyleneimine, chitosan, lipids, and poly‐l‐lysine), followed by capping with shellac. This nanoparticle platform enables mRNA transfection following intravenous injection and facilitates gene editing

Oxygen Supply of Islets of Langerhans by Photosynthetically Active Microalgae in Bioprinted Co‐Cultures Maintains Their Function in a Hypoxic Environment

Advanced Healthcare Materials, EarlyView.
This study developed a bioprinted co‐culture system embedding rat pancreatic islets and Scenedesmus sp. microalgae spatially defined in close vicinity. Red light was found optimal to ensure microalgal photosynthesis while maintaining islet viability and functionality. A tailored co‐culture medium supported both cell types.
