Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics

open access: yesAdvanced Materials, Volume 37, Issue 13, April 2, 2025.
Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.

Phonon Driven Ferroelectricity and Raman Active Modes in Hybrid Organic‐Inorganic Perovskites

open access: yesAdvanced Materials, EarlyView.
Ferroelectric domains, a hallmark of ferroelectricity, are studied using temperature‐dependent Raman spectroscopy to uncover characteristic phonons associated with ferroelectric phase transitions in different n‐value HOIPs. Higher n‐value HOIP demonstrate a reduced ferroelectric switching energy barrier, providing valuable insights for optimizing ...

Flexible Selenium Nanowires with Tuneable Electronic Bandgaps

open access: yesAdvanced Materials, EarlyView.
Nanotubes serve as effective test tubes for selenium nanowires, as their diameter precisely controls the width of the nanowires and the Se─Se bonding, resulting in a variety of different structures. An electron beam can be used to modify the nanotubes, allowing real‐time observation of the nanowire extrusion process. Additionally, optically transparent

Formation of Jet-driven Forced Reconnection Region and Associated Plasma Blobs in a Prominence Segment

open access: yesThe Astrophysical Journal
We use data from the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory to study the most likely formation of a forced reconnection region and associated plasma blobs, triggered by jetlike structures in a prominence segment.
