Defect Passivation via Plasma Modification of Lead Halide Perovskite Thin Films

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
We demonstrate that exposure of perovskite thin films to diffuse coplanar surface barrier discharge nitrogen plasma leads to an increase in photoluminescence, attributed to reduced defect densities. This results in implied open‐circuit voltage improvement of up to 80 mV and finalized solar cell open‐circuit gains up to 60 mV.

Cationic‐Hydrophilic Di‐Block Copolymers: Surface‐Shielded Vectors for Gene Delivery

open access: yesJournal of Polymer Science, Volume 63, Issue 6, Page 1419-1432, 15 March 2025.
This study develops synthetic polycationic di‐block carriers for nucleic acid (NA) delivery in gene therapy. Consisting of a cationic block and a hydrophilic block, these carriers efficiently form complexes with NAs and shield them with a protective bioinert layer, enhancing stability during circulation in the bloodstream while reducing undesirable ...

Identification of initial vegetation and habitat changes in small temperate fens using remote sensing

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Temperate fens with only incipient, subtle signs of deterioration can be reliably identified using Sentinel‐2 and aerial imagery, which sensitively detect early productivity‐related structural changes. Abstract Small temperate fens rank among the most endangered habitats in temperate Europe.
