Simple and Effective Patterning Method of Liquid‐Metal‐Infused Sponge Electrode for Fabricating 3D Stretchable Electronics
Authors: Kim Seonghyeon , Yoo Dongwoo , Lim Jongkyeong , Kim Joonwon 
Published: January 2024

AbstractStretchable electrodes have emerged as a promising technology for soft robotics and wearable devices. One fabrication method that guarantees sustained elasticity and high conductivity is directly filling or printing an elastic substrate with liquid metal (LM). However, it is difficult to create patterns with complex or 3D shapes, such as hole patterning, integration electrodes, and flexible breadboards. Therefore, a simple and effective patterning method for fabricating 3D stretchable electronics using LM electrodes is proposed in this study. The LM‐infused sponge electrode is fabricated by loading LM onto a polydimethylsiloxane (PDMS) sponge, which is fabricated using the salt‐leaching method in PDMS patterned by replica molding. The LM‐infused sponge electrode exhibits a minimal change in terms of resistivity under strain, bending, and twisting (∆R < 0.01 Ω cm−1). This enables various devices to be driven by the production of flexible breadboards, which makes it possible to integrate the proposed model into commercial electronics. Finally, a stretchable tactile sensor (self‐capacitive and self‐powered) is fabricated by integrating stretchable electrodes using only the LM‐infused sponges. In the future, stretchable electrodes fabricated in this manner can be used in various applications, such as soft robots and wearable devices.

Published: January 2024

AbstractAs the development of flexible electronics continuously progresses, so does the demand for fabricated 3D electrodes via patterning technology. Electrochemical replication and transfer (ERT) has emerged as an efficient patterning technique, which deposits materials of interest on a predefined template via electroplating and subsequently transfers them onto target substrates. ERT can pattern large‐area 2D electrodes on nontraditional substrates whilst maintaining adequate flexibility, stretchability, and complex surface structures. This study extends the capability of ERT from 2D into 3D patterning. Via the rational design of a 3D SiO2/Si template, in which conductive Si trenches or holes are patterned with insulating SiO2 banks, electroplating of materials only occurs in the exposed Si surfaces so that both continuous and isolated 3D patterns with high aspect ratios up to 4:1 are realized. 3D‐ERT offers a high‐throughput and low‐cost approach to fabricating high Figure of Merit (>30 000) flexible transparent electrodes. Also, the application of 3D‐ERT in constructing highly sensitive, and self‐powered pressure sensors is showcased.

AbstractExploring robust blue luminescent materials is of high significance but challenging for the commercialization application of organic light‐emitting diodes (OLEDs). In this work, it is wished to report two blue thermally activated delayed fluorescence (TADF) molecules with a through‐space charge transfer feature. They have sandwich‐structured molecular backbones comprised of one triphenyltriazine acceptor and two 9‐phenylcarbazole or 3,6‐di(tert‐butyl)‐9‐phenylcarbazole donors that are linked at the 1,8,9‐positions of a 3,6‐di(tert‐butyl)carbazole holder, and exhibit high thermal stability and strong blue delayed fluorescence with high photoluminescence quantum yields and fast reverse intersystem crossing. The blue OLEDs use 2TBCTC as an emitter and provide outstanding maximum external quantum efficiencies (EQEmaxs) of up to 32.76% with Commission Internationale de I'Eclairage coordinates of (0.160, 0.206). To the best of knowledge, 2TBCTC is the most efficient blue TADF emitter based on through‐space charge transfer in the literature. Moreover, the interlayer‐sensitizing OLED employs 2TBCTC as a sensitizer for blue multi‐resonance TADF (MR‐TADF) molecule (v‐DABNA) as guest emitter attains an excellent EQEmax of 32.69% with a narrow full width at half maximum of 18 nm, validating the excellent potential of 2TBCTC as sensitizer for MR‐TADF emitters and the feasibility and effectiveness of the interlayer sensitization strategy for blue hyperfluorescence OLEDs.
Perfect Absorption with Independent Electric and Magnetic Lattice Resonances in Metallo‐Dielectric Arrays

Published: January 2024

AbstractLattice resonances are collective modes supported by periodic arrays of nanostructures. They originate from the coherent interaction between the localized modes of the individual constituents of the array, which, for systems made of metallic nanostructures, usually correspond to the electric dipole plasmon. Unfortunately, fundamental symmetry reasons preclude a two‐dimensional (2D) arrangement of electric dipoles from absorbing more than half the incident power, thus imposing a strong limitation on the performance of conventional lattice resonances. This work introduces an innovative solution to overcome this constraint, which is based on using an array made of a unit cell containing one metallic and one dielectric nanostructure. Using a rigorous coupled dipole model, it is shown that this system can support two independent lattice resonances associated, respectively, with the electric and magnetic dipole modes of the nanostructures. By adjusting the geometrical characteristics of the array, these two lattice resonances can be meticulously aligned in the spectral domain, leading to the total absorption of the incident power. The results of this work provide clear, yet general, guidelines for the rational design of arrays sustaining lattice resonances capable of producing perfect absorption, thus leveraging the potential of these modes for applications requiring an efficient absorption of light.

Published: January 2024

AbstractIntroducing chirality into organic/inorganic hybrid materials can impart chiroptical properties such as circular dichroism. The ability to tune chiroptical properties in self‐assembled materials can have important implications for spintronic and optoelectronic applications. Here, a chiral organic cation, (R/S)‐4‐methoxy‐α‐methylbenzylammonium, is incorporated to synthesize the bismuth‐based hybrid organic–inorganic metal halide semiconductor, (R/S‐MeOMePMA)BiI4. Thin films of this Bi‐based compound demonstrate large chiroptical responses, with circular dichroism anisotropy (gCD) values up to ≈0.1, close to the highest value observed in another chiral metal‐halide semiconductor, (R‐MBA2CuCl4). Detailed investigation reveals that this large gCD in (R/S‐MeOMePMA)BiI4 is caused by the apparent CD effect. Careful selection of deposition conditions and the concomitant thin‐film orientation enables the control of gCD, with maximum value observed when its thin film has a well‐crystallized preferred (001) orientation parallel to the substrate. The results support a growing body of evidence that low symmetry plays an important role in achieving unusually large gCD in these chiral metal–halide materials and provides design rules for achieving large chiroptical response via morphology control.

AbstractIn South and Southeast Asia, the habit of chewing betel nuts is prevalent, which leads to oral submucous fibrosis (OSF). OSF is a well‐established precancerous lesion, and a portion of OSF cases eventually progress to oral squamous cell carcinoma (OSCC). However, the specific molecular mechanisms underlying the malignant transformation of OSCC from OSF are poorly understood. In this study, the leading‐edge techniques of Spatial Transcriptomics (ST) and Spatial Metabolomics (SM) are integrated to obtain spatial location information of cancer cells, fibroblasts, and immune cells, as well as the transcriptomic and metabolomic landscapes in OSF‐derived OSCC tissues. This work reveals for the first time that some OSF‐derived OSCC cells undergo partial epithelial–mesenchymal transition (pEMT) within the in situ carcinoma (ISC) region, eventually acquiring fibroblast‐like phenotypes and participating in collagen deposition. Complex interactions among epithelial cells, fibroblasts, and immune cells in the tumor microenvironment are demonstrated. Most importantly, significant metabolic reprogramming in OSF‐derived OSCC, including abnormal polyamine metabolism, potentially playing a pivotal role in promoting tumorigenesis and immune evasion is discovered. The ST and SM data in this study shed new light on deciphering the mechanisms of OSF‐derived OSCC. The work also offers invaluable clues for the prevention and treatment of OSCC.

Published: January 2024

AbstractBiological macromolecules exhibit emergent functions through hierarchical self‐assembly, a concept that is extended to design artificial supramolecular assemblies. Here, the first example of breaking the common parallel arrangement of capsule‐shaped zirconium coordination cages is reported by constructing the hierarchical porous framework ZrR‐1. ZrR‐1 adopts a quaternary structure resembling protein and contains 12‐connected chloride clusters, representing the highest connectivity for zirconium‐based cages reported thus far. Compared to the parallel framework ZrR‐2, ZrR‐1 demonstrated enhanced stability in acidic aqueous solutions and a tenfold increase in BET surface area (879 m2 g−1). ZrR‐1 also exhibits excellent proton conductivity, reaching 1.31 × 10−2 S·cm−1 at 353 K and 98% relative humidity, with a low activation energy of 0.143 eV. This finding provides insights into controlling the hierarchical self‐assembly of metal–organic cages to discover superstructures with emergent properties.

Published: January 2024

AbstractResistive random‐access memories (ReRAM) are promising candidates for next‐generation non‐volatile memory, logic components, and bioinspired neuromorphic computing applications. The analog resistive switching (RS) tuning with a sizable memory window is crucial for realizing multi‐level storage devices. This work demonstrates the multi‐level storage capability of fabricated Ag/NiO/W ReRAM architecture, controlled through voltage modulations. The fabricated ReRAM structures exhibit stable bipolar analog RS, non‐overlapping resistance, and endurance of ≈104 cycles, respectively, with marginal statistical variations/fluctuations. Also, the fabricated ReRAM offers highly controlled and stable retention characteristics tested up to ≈104 s with significantly controlled statistical variations/fluctuations. Adjacent thereto, it offers a substantially lower operating SET and RESET voltage of 1 and −1 V, respectively. Moreover, the non‐overlapping multiple resistive states are observed with the voltage pulse modulation schemes. Furthermore, the current switching mechanism is described using a model proposed for the conductive filament growth and the contribution of the NiO/W interface layer (IL) toward notable RS of fabricated Ag/NiO/W structures.

Published: January 2024

AbstractExtended defects, including exposed surfaces and grain boundaries (GBs), are critical to the properties of polycrystalline solid electrolytes in all‐solid‐state batteries (ASSBs). These defects can alter the mechanical and electronic properties of solid electrolytes, with direct manifestations in the performance of ASSBs. Here, by building a library of 590 surfaces and grain boundaries of 11 relevant solid electrolytes—including halides, oxides, and sulfides— their electronic, mechanical, and thermodynamic characteristics are linked to the functional properties of polycrystalline solid electrolytes. It is found that the energy required to mechanically “separate” grain boundaries can be significantly lower than in the bulk region of materials, which can trigger preferential cracking of solid electrolyte particles in the grain boundary regions. The brittleness of ceramic solid electrolytes, inferred from the predicted low fracture toughness at the grain boundaries, contributes to their cracking under local pressure imparted by lithium (sodium) penetration in the grain boundaries. Extended defects of solid electrolytes introduce new electronic interfacial states within bandgaps of solid electrolytes. These states alter and possibly increase locally the availability of free electrons and holes in solid electrolytes. Factoring effects arising from extended defects appear crucial to explain electrochemical and mechanical observations in ASSBs.

Published: January 2024

AbstractWe examine the association between woman farmers and community well‐being using U.S. county‐level data. We address modeling uncertainty around three measures of community well‐being by using a spatial Bayesian model averaging approach and find that a higher share of farms operated or owned by women in a county is associated with higher rates of new business formation, longer life expectancies, and lower poverty rates. The results are consistent with a growing literature that finds women business owners approach their businesses more holistically, with positive community spillovers.

Published: January 2024

Key points
Expanded types of functional endoscopic sinus surgery (FESS) significantly improve quality of life and reduce revision surgeries rates, supporting their early application for moderate‐to‐severe cases.
Minimal clinically important difference may play as a crucial role in defining surgical treatment response (i.e., responder and super‐responder conditions).
Expanded FESS benefits patients with chronic rhinosinusitis with nasal polyps but more data are required to have a clearer understanding of its uses due to varied approaches and reported outcomes in the literature.

AbstractDNA topoisomerases are attractive targets for anticancer agents. Dual topoisomerase I/II inhibitors are particularly appealing due to their reduced rates of resistance. A number of therapeutically relevant topoisomerase inhibitors are bacterial natural products. Mining the untapped chemical diversity encoded by soil microbiomes presents an opportunity to identify additional natural topoisomerase inhibitors. Here we couple metagenome mining, bioinformatic structure prediction algorithms, and chemical synthesis to produce the dual topoisomerase inhibitor tapcin. Tapcin is a mixed p‐aminobenzoic acid (PABA)‐thiazole with a rare tri‐thiazole substructure and picomolar antiproliferative activity. Tapcin reduced colorectal adenocarcinoma HT‐29 cell proliferation and tumor volume in mouse hollow fiber and xenograft models, respectively. In both studies it showed similar activity to the clinically used topoisomerase I inhibitor irinotecan. The study suggests that the interrogation of soil microbiomes using synthetic bioinformatic natural product methods has the potential to be a rewarding strategy for identifying potent, biomedically relevant, antiproliferative agents.

Published: January 2024

AbstractCarbon‐based single‐atom catalysts (SACs) have attracted tremendous interest in heterogeneous catalysis. However, the common electric heating techniques to produce carbon‐based SACs usually suffer from prolonged heating time and tedious operations. Herein, a general and facile microwave‐assisted rapid pyrolysis method is developed to afford carbon‐based SACs within 3 min without inert gas protection. The obtained carbon‐based SACs present high porosity and comparable carbonization degree to those obtained by electric heating techniques. Specifically, the single‐atom Ni implanted N‐doped carbon (Ni1−N−C) derived from a Ni‐doped metal–organic framework (Ni‐ZIF‐8) exhibits remarkable CO Faradaic efficiency (96 %) with a substantial CO partial current density (jCO) up to 1.06 A/cm2 in CO2 electroreduction, far superior to the counterpart obtained by traditional pyrolysis with electric heating. Mechanism investigations reveal that the resulting Ni1−N−C presents abundant defective sites and mesoporous structure, greatly facilitating CO2 adsorption and mass transfer. This work establishes a versatile approach to rapid and large‐scale synthesis of SACs as well as other carbon‐based materials for efficient catalysis.

AbstractAlthough colloidal perovskite nanocrystal (PNC) solution has exhibited near‐unity photoluminescence quantum yield (PLQY), the luminance would be severely quenched when the PNC solution is assembled into thin films due to the agglomeration and fusion of NCs caused by the exfoliation of surface ligands and non‐radiative Förster resonance energy transfer (FRET) from small to large particle sizes, which seriously affected the performances of light‐emitting diodes (LEDs). Here, we used Guanidine thiocyanate (GASCN) and Sodium thiocyanate (NaSCN) to achieve effective CsPbI3 PNC surface reconstruction. Due to the strong coordination ability of these small molecules with the anions and cations on the surface of the PNCs, they can provide strong surface protection against PNC fusion during centrifugal purification process and repair the surface defects of PNCs, so that the original uniform size distribution of PNCs can be maintained and FRET between close‐packed PNC films is effectively suppressed, which allows the emission characteristics of the films to be preserved. As a result, highly oriented, smooth and nearly defect‐free high‐quality PNC thin films are obtained, with PLQY as high as 95.1 %, far exceeding that of the original film, and corresponding LEDs exhibit a maximum external quantum efficiency of 24.5 %.

AbstractPhotoinduced 3D printing based on the reversible addition‐fragmentation chain transfer (RAFT) process has emerged as a robust method for creating diverse functional materials. However, achieving precise control over the mechanical properties of these printed objects remains a critical challenge for practical application. Here, we demonstrated a RAFT step‐growth polymerization of a bifunctional xanthate and bifunctional vinyl acetate. Additionally, we demonstrated photoinduced 3D printing through RAFT step‐growth polymerization with a tetrafunctional xanthate and a bifunctional vinyl acetate. By adjusting the molar ratio of the components in the printing resins, we finely tuned the polymerization mechanism from step‐growth to chain‐growth. This adjustment resulted in a remarkable range of tunable Young's moduli, ranging from 7.6 MPa to 997.1 MPa. Moreover, post‐functionalization and polymer welding of the printed objects with varying mechanical properties opens up a promising way to produce tailor‐made materials with specific and tunable properties.

Published: January 2024

AbstractGenerally, two‐dimensional gold nanomaterials have unique properties and functions that offer exciting application prospects. However, the crystal phases of these materials tend to be limited to the thermodynamically stable crystal structure. Herein, we report a DNA framework‐templated approach for the ambient aqueous synthesis of freestanding and microscale amorphous gold nanosheets with ultrathin sub‐nanometer thickness. We observe that extended single‐stranded DNA on DNA nanosheets can induce site‐specific metallization and enable precise modification of the metalized nanostructures at predefined positions. More importantly, the as‐prepared gold nanosheets can serve as an electrocatalyst for glucose oxidase‐catalyzed aerobic oxidation, exhibiting enhanced electrocatalytic activity (~3‐fold) relative to discrete gold nanoclusters owing to a larger electrochemical active area and wider band gap. The proposed DNA framework‐templated metallization strategy is expected to be applicable in a broad range of fields, from catalysis to new energy materials.
