Disentangling the absorption lineshape of methylene blue for nanocavity strong coupling

open access: yesNanophotonics, Volume 14, Issue 27, Page 4993-5001, December 2025.
Abstract Cucurbit[7]uril molecules form non‐covalent host – guest complexes with small molecular dyes. In addition, cucurbit[7]uril can also bind gold nanoparticles on gold surfaces with a 0.9 nm gap, creating plasmonic nanocavities for the dyes, with extreme confinement of the electromagnetic field. For methylene blue in such cavities, single molecule

Effects of the Operating Point of Photovoltaic Strings on Sizing of DC‐ and AC‐Connected Energy Storage Systems for Power Smoothing

open access: yesAdvanced Energy and Sustainability Research, Volume 6, Issue 10, October 2025.
This study is based on measured current–voltage curves of a 23 module photovoltaic (PV) string. The results of the study show that, in practice, following the maximum power point (MPP) closest to the nominal MPP voltage instead of the global MPP has no major effect on sizing of energy storage systems for power smoothing of PV strings. Photovoltaic (PV)

Superhydrophobic Cell‐Repellent Microstructures: Plastron‐Mediated Inhibition of A549 Epithelial Cell Adhesion

open access: yesSmall, Volume 21, Issue 40, October 9, 2025.
Engineered superhydrophobic micropillars reduced A549 cell adhesion tenfold after 1 day of incubation via a plastron‐mediated physical repellency mechanism, independent of cell‐surface biochemical interactions. Microstructured surfaces outperformed nanostructures, providing the first experimental evidence of microscale superiority.

Praktiska moment på distans – Form och ämnesinnehåll i naturvetenskap och teknik inom grundlärarutbildningen under covid-19-pandemin

open access: yesHögre Utbildning, 2022
Lärarutbildningar har ett dubbelt uppdrag. Dels ska studenterna få kunskaper i att undervisa ett specifikt ämnesinnehåll, dels ska studenterna få exempel på hur ämnesinnehållet kan undervisas om i skolan.

Screening of Material Defects using Universal Machine‐Learning Interatomic Potentials

open access: yesSmall, Volume 21, Issue 37, September 18, 2025.
The accuracy of universal machine‐learning interatomic potentials for defect screening are benchmarked and found to yield sufficiently reliably results for vacancies. High‐throughput vacancy formation energy calculations are carried out for 86,259 materials.

Elevers samtal om en PISA-uppgift - Naturvetenskap i olika skolkontexter

open access: yesUtbildning & Demokrati, 2019
In this article, we assume that discursive language aspects are highly intertwined with students’ knowledge building and learning in science. The article analyses students’ collaborative discussions about a PISA assignment in science.

Halogen‐Bonded Liquid Crystal Elastomers as Initiator‐Free Photochemical Actuators

open access: yesAdvanced Materials, Volume 37, Issue 33, August 21, 2025.
The combination of dynamic disulfide bonds and halogen bonds in chain‐extended liquid crystal elastomers enables the fabrication of photochemical actuators without the need for a photoinitiator, advancing the design of multimodal soft actuators that can be reprogrammed and reprocessed through supramolecular functionalization.
