Tillsammans för praxisutveckling: En aktionsforskningsstudie med rektorer i småkommuner

open access: yesForskning og Forandring
Artikeln har sin utgångspunkt i en aktionsforskningspraktik som fokuserar skolledarskap i svenska småkommuner. Med stöd i teorin om praktikarkitekturer och en modell för etiskt ledarskap analyseras om, och i så fall hur, aktionsforskning kan stödja och ...

Multifunctional Thiolated Hyaluronic Acid‐graft‐PEDOT Dressing With Antifouling, On‐Demand Drug Delivery and Electrical Stimulation for Wound Healing

open access: yesAdvanced Healthcare Materials, EarlyView.
A multifunctional P(EDOT‐co‐EDOT‐g‐THA) dressing acts as a dynamic biointerface integrating antifouling capability, on‐demand drug delivery, and electrical stimulation. It achieves electrochemically triggered thiolated hyaluronic acid (THA) release while modulating cellular responses for wound healing application.

Att arbeta med upplevelsebaserat lärande i universitetsmiljö: Förutsättningar och hinder

open access: yesHögre Utbildning
Upplevelsebaserat lärande, exempelvis genom simulationer, rollspel och praktiska övningar, har länge varit en del av många akademiska utbildningar. Trots detta finns det en brist på kunskap om hur denna lärandeform kan integreras i den akademiska miljön.

Counterintuitive Fluorescence Blue Shift in Symmetry Breaking Dicationic Bis(indolium) with Two‐Photon Absorption Properties for NIR Living Cell Imaging

open access: yesAdvanced Materials, EarlyView.
Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

open access: yesAdvanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Ultrafast Vertical Organic Electrochemical Transistors With Ion‐Permeable Conductive Polymer Top Electrodes

open access: yesAdvanced Materials, EarlyView.
Vertical organic electrochemical transistors (vOECTs) are limited in speed by ion‐impermeable metal electrodes that slow ion injection. Using ion‐permeable PBFDO top electrodes allows direct vertical ion injection into BBL channels, achieving high current densities (>400 A cm−2), large on/off ratios (>106), and ultrafast switching in 28 µs. This sets a

Sveriges jordbruksområden [PDF]

open access: yes, 2006
In Sweden there are mainly three ways to classify different regions according to production conditions. In the beginning of the 20th century, Sweden was divided into 55 so called natural agricultural areas. Today, Sweden consists of 61 such areas. In Official Statistics of Sweden, yearbook of agricultural statistics, these agricultural areas are merged

Photoactive Tweezers

open access: yesAdvanced Materials, EarlyView.
A photoactive tweezers system based on photoactive colloids is developed and systematically investigated in this study. Through experimental and theoretical methods, we demonstrate that the photoredox reaction catalyzed by a dye‐sensitized TiO2 particle generates a strong positive phototaxis, enabling self‐entrapment in the beam center.

Deterministic Nucleation of Nanocrystal Superlattices on 2D Perovskites for Light‐Funneling Heterostructures

open access: yesAdvanced Materials, EarlyView.
This work investigates the heterogeneous nucleation of CsPbBr3${\rm CsPbBr}_3$ nanocrystal superlattices along the faces of 2D PEA2PbBr4${\rm PEA}_2{\rm PbBr}_4$ layered perovskite microcrystals. Core–crown and core–shell heterostructure morphologies are obtained.
