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.

This research presents an easy to fabricate, low‐cost, flexible piezoresistive deformation sensor comprised of a carbon nanotube, few‐layer graphene, and polydimethylsiloxane composite. The sensor detects deformations and vibrations up to 600 Hz with 0.1% strain sensitivity from stiff and soft targets in dry and wet environments.

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 ...

Demonstration of an electro‐optic phase shifter fabricated by inkjet printing liquid crystal on an integrated silicon photonics chip surface. On a completed silicon photonics wafer (including modulators, detectors, and metallization), the back‐end‐of‐line stack is opened up to inkjet‐print liquid crystal. A phase shift of 6 for 2.7 V is obtained within

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

This work combines molecular dynamics and finite‐difference time‐domain computational approaches to study the photothermal properties of melanin nanoparticle–based supra‐assemblies. Based on the results of this study, the binary mixtures of melanin and silica with higher concentrations of melanin and with more segregated levels of mixing are able to ...
