Traceless Photopolymerization with Non‐Pulsed Red Light Enables 3D‐Printable Cell‐Laden Hydrogels
Advanced Materials, Volume 37, Issue 30, July 29, 2025.The paper presents a red‐light‐induced polymerization process, initiated by the FDA‐approved dye methylene blue and the cytocompatible co‐initiator triethanolamine, for fabricating hydrogels. This photopolymerization process is oxygen‐tolerant, cytocompatible, and, most importantly, leaves no color traces, resulting in completely transparent scaffolds.

Advanced Biology, Volume 9, Issue 5, May 2025.Positively supercharged mGreenLatern protein is self‐assembled electrostatically with negatively charged zinc phthalocyanines to yield bio‐based photoactive materials in aqueous media. The addition of phthalocyanines results in the formation of large complexes fully quenching of the protein fluorescence. The results indicate an energy transfer from the

Folding of mRNA‐DNA Origami for Controlled Translation and Viral Vector Packaging
Advanced Materials, Volume 37, Issue 15, April 16, 2025.The packaging of mRNA into a compact, predefined shape can impact cellular delivery. This study presents a first set of design rules for the efficient folding of mRNA‐DNA origami structures, while preserving its initial translation functionality, which is demonstrated extracellularly as well as in vitro by using virus capsid proteins for packaging and ...

Redox‐Active Bisphosphonate‐Based Viologens as Negolytes for Aqueous Organic Flow Batteries
Chemistry – A European Journal, Volume 31, Issue 16, March 17, 2025.Bisphosphonate‐substituted viologens (BBPE‐Vi and MBPE‐Vi) exhibit high solubility (1.45 M) and stability (0.009% capacity decay per cycle), making them effective for AOFBs. The bulky, negatively charged bisphosphonate groups reduce degradation through bimolecular side reactions, while their electron‐rich character in the deprotonated state effectively

Perovskite‐Inspired Cs₂AgBi₂I₉: A Promising Photovoltaic Absorber for Diverse Indoor Environments
Advanced Energy Materials, Volume 15, Issue 7, February 18, 2025.This study have developed polycrystalline Cs₂AgBi₂I₉, a promising material for indoor photovoltaics (IPVs). Cs₂AgBi₂I₉ films have intriguing properties, such as weak electron‐phonon coupling and low exciton binding energy, which are advantageous for photovoltaic applications. Cs₂AgBi₂I₉ devices have demonstrated ≈8% efficiency at 1000 lux. They perform

Naturvetenskap i förskolan- Utemiljöns betydelse för barns lärande inom naturvetenskap
, 2012 Syftet med vår undersökning var att jämföra tre förskolor med olika utemiljöer för att undersöka hur pedagogerna uppfattade förskolans utemiljö samt hur de arbetade med naturvetenskap med barnen. Utifrån våra frågeställningar Hur uppfattar pedagoger utemiljön på sina förskolor för att möjliggöra barns lärande inom naturvetenskap?
