Suppression of Stacking Faults for Stable Formamidinium‐Rich Perovskite Absorbers

Advanced Materials, Volume 37, Issue 26, July 3, 2025.
The authors show that the (011)C perovskite planes are prone to stacking faults formation in all leading formamidinium‐rich perovskite compositions. Using ethylene thiourea as a precursor additive, Othman et al. suppress those vulnerable facets, significantly enhancing the absorber's intrinsic stability under various operational conditions.

Revealing Trapped Carrier Dynamics at Buried Interfaces in Perovskite Solar Cells via Infrared‐Modulated Action Spectroscopy with Surface Photovoltage Detection

Advanced Materials, Volume 37, Issue 26, July 3, 2025.
A new spectroscopy technique (i.e., pump‐push‐surface photovoltage) is introduced that monitors trapped carrier dynamics at the buried interfaces in perovskite solar cells (PeSCs) via combining optical trap activation by infrared light with surface photovoltage detection.

Thermally Activated Swelling and Wetting Transition of Frozen Polymer Brushes:a New Concept for Surface Functionalization

Advanced Materials, Volume 37, Issue 26, July 3, 2025.
A novel approach is introduced that leverages polymer phase transitions to modulate brush behavior. The oleophilic bottle brush system exhibits two distinct melting transitions—bulk and surface—enabling a two‐stage swelling and wetting transition.

Engineering Cellular Self‐Adhesions Inside 3D Printed Micro‐Arches to Enhance Cell:Biomaterial Attachment

Advanced Materials, EarlyView.
Surprisingly, a cell can bind to itself to make a self‐adhesion, which engineered here to improve how cells attach to biomaterials. Nanoprinting are used to make 3D structures smaller than cells–called Self‐Adhesion‐Tunnels (SATs)–around which cells can wrap and bind to themselves.

Ultrafast Light‐Driven Electronic and Structural Changes in LaFeO3 Perovskites Probed by Femtosecond X‐Ray Absorption Spectroscopy

Advanced Materials, EarlyView.
Femtosecond X‐ray absorption spectroscopy (fs‐XAS) at PAL‐XFEL captures ultrafast electronic and structural dynamics in epitaxial LaFeO3 thin films. Combined with DFT and multiplet calculations, the study reveals photoinduced ligand‐to‐metal charge transfer, followed by polaron formation and reduced oxygen 2p‐iron 3d hybridization, explaining key ...

Reconfigurable Liquid Crystal‐Based Physical Unclonable Function Integrating Optical and Electrical Responses

Advanced Materials, EarlyView.
Reconfigurable physical unclonable function (PUF) integrating optical and electrical responses in organic field‐effect transistor is developed by using unique optical fingerprint textures and random molecular alignment of the semiconductive smectic liquid crystal. This approach enhances security by enabling hierarchical authentication, providing robust
