This study presents a low‐cost technique to analyze hidden layers in perovskite solar cells during operation. By modifying nickel oxide with an ionic liquid, the researchers improved its interaction with the perovskite layer, enhancing charge transfer. The method helps quickly optimize interface treatments and can be applied to other electronic devices

Printed Interconnects for Heterogeneous Systems Integration on Flexible Substrates
Key components (sensors, energy devices, communication devices, computing chips, and interconnects) of flexible hybrid electronic (FHE) system connected via conductive printed metal tracks. The figure in the insets shows out‐of‐plane printed interconnects providing opportunities for lithography‐free formation of VIAs, in‐plane access of UTCs pads, and ...

This article introduces a hybrid manufacturing approach to create conductive pathways in additively manufactured fully‐aromatic polyimides. This is enabled through a combination of high‐resolution laser scribing process for fabricating graphene and metallizing it with electrodeposition of copper to further increase conductivity.

Strategic Direct Printing for High‐Performance and Uniform Organic Thin‐Film Transistor Arrays
This work presents a strategic direct‐printing approach to achieve high‐performance printed organic thin‐film transistor arrays. A 12 × 12 printed transistor array with high electrical performances is successfully demonstrated, achieving a saturation mobility of 0.9 cm2·V−¹·s−¹ and a relative standard deviation of 14.4%.

Architected Elastomers as Load Bearing Actuators for Untethered Soft Robot Walking
Electrically driven soft actuators that enable untethered soft robot walking are developed from 3D printed architected elastomers. The actuators have a handed shearing auxetic structure that enables fast, robust, and battery‐powered motions. The actuators are 3D printed from thermoplastic polyurethane on a desktop FDM printer.

Chalcogenide optical PCMs have gathered interest for their potential in compact, non‐volatile optics and photonics. Free‐space PCM metasurfaces require new considerations from phase change memory that need to be addressed for reliable scale‐up. Several failure mechanisms pertaining to free‐space PCM devices and layout methods are isolated to prevent ...

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...
