Published: August 2024

AbstractMost flexible human–machine interfaces emulate the tactile system of the skin, which has the risk of contact damage. Additionally, contact deformation often leads to a hysteresis response. Non‐contact interaction can address these problems. Inspired by the electroreception capabilities of the elephantnose fish, this study introduces a non‐contact sensing model employing monopolar controlled ionic hydrogel. Compared to most existing mutual capacitive non‐contact sensing models, this model not only boosts responsivity by over 3.5 times but also streamlines the sensing architecture. Utilizing this sensing model, a flexible non‐contact human–machine interface is developed by organizing three differently shaped hydrogels into an asymmetric configuration. This device reliably discerns six non‐contact gestures using machine learning algorithms and supports at least eleven interactive functions by detecting the duration of gestures, enabling continuous real‐time control over external devices. This advancement heralds a more liberated paradigm of human–machine interaction with promising implications for the Internet of Things.

AbstractIn the past, considerable effort are focused on advancing blue organic light‐emitting diodes (OLEDs) based on 1,3‐bis(N‐carbazolyl)benzene (mCP). To enhance and stabilize the device performance in vacuum‐processed OLEDs, it is essential to optimize the thermally stable organic materials constituting the emitting layer. The proposed novel carbazole derivative, Ad‐mCP, is designed and synthesized as a host material for blue thermally activated delayed fluorescence OLEDs, which are ideal for vacuum processing. Ad‐mCP exhibits a high glass transition temperature and triplet energy (T1), making it highly compatible with the blue dopant 2,11,14‐tri‐tert‐butyl‐N,N,5‐tris(4‐(tert‐butyl)phenyl)−5H‐5,8b‐diaza‐15b‐borabenzo[a]naphtho[1,2,3‐hi]aceanthrylen‐7‐amine emitter. The incorporation of a rigid adamantane unit into the carbazole group modifies the molecular structure of mCP, preserving crucial photophysical properties, such as T1,while enhancing the morphological and thermal stability of the host material in its film state. Moreover, the spatially hindered molecular structure of Ad‐mCP improves the photoluminescent quantum yield of the emissive layer and enhances charge balance, crucially contributing to the overall efficiency of the OLEDs. As a result, the exceptional performance of Ad‐mCP as a host material for OLEDs resulted in a remarkably high maximum external quantum efficiency of 29.9%, demonstrating superior stability in efficiency even after thermal annealing compared to mCP devices.

AbstractWearable technology is experiencing remarkable progress, prompting the need for sustainable power sources like triboelectric nanogenerators (TENGs). However, integrating TENGs into fabrics and insufficient power outputs that allows for comfortable wear without obstructing user's movements presents a significant challenge. In this study, a novel kind of diamond‐structured fabric‐based triboelectric nanogenerators (DSF‐TENGs) is introduced utilizing an easy, economical, and scalable weaving method without any chemical modification. Owing to its 3D diamond pattern, surface interactions are enhanced for greater charge generation together with strengthened mechanical engagement for more effective charge transfer. The DSF‐TENG, with its unique self‐resilient structure, achieves impressive electric performance, including output voltage of ≈763 V, short‐circuit current of ≈20.4 µA, and power density of 2862.78 mW m−2, which is multiple times higher than most existing fabric‐based TENGs. It also offers excellent air permeability of 560 mm s−1, consistent electricity generation and sensing even after ten washing cycles, and incredible durability, withstanding over 30 000 cycles. Furthermore, DSF‐TENG is included in an insole that is capable of sensing gait patterns, walking speed, and fall detections of patients with Parkinson's disease. The remarkable power generation capabilities of DSF‐TENG indicate a strong potential for future developments in wearable electronics and healthcare applications.

AbstractThe electrocatalytic recycling of waste nitrate (NO3RR) is a promising decentralized route for green ammonia synthesis. Nonetheless, it suffers from the competing hydrogen evolution reaction and the insufficient proton supply in high pH conditions. Herein, iron oxide nanoparticles anchored on ZnO is introduced as a strategy to enhance the water dissociation ability and proton transfer rate, advancing NH4+ production from alkaline NO3RR. Supported by a set of ex situ and in situ characterization, the findings reveal the reduction of iron oxides, along with improvements in charge transfer properties and proton generation from H2O. Theoretical calculations show that iron oxides reduce the kinetic barrier of the rate‐limiting step (*NO2‐to‐*NO2H) and result in a thermodynamically favorable process to hydrogenation steps, which in turn reduce the overall energy barrier of alkaline NO3RR. Optimal catalytic activity is realized with a Fe loading of 0.5 wt.%, delivering a Faradaic efficiency of ≈83% for ammonium with a NH4+ yield rate of 31 nmol s−1 cm−2 at −0.7 V versus RHE. The results pave the way for the utilization of bi‐metal interaction to tune the reaction pathway for achieving sustainable ammonium synthesis in alkaline, contributing to ongoing efforts to achieve a sustainable nitrogen cycle via N‐based electrochemistry.

AbstractBionic electrical stimulation (Bio‐ES) aims to achieve personalized therapy and proprioceptive adaptation by mimicking natural neural signatures of the body, while current Bio‐ES devices are reliant on complex sensing and computational simulation systems, thus often limited by the low‐fidelity of simulated electrical signals, and failure of interface information interaction due to the mechanical mismatch between soft tissues and rigid electrodes. Here, the study presents a flexible and ultrathin self‐sustainable bioelectronic patch (Bio‐patch), which can self‐adhere to the lesion area of organs and generate bionic electrical signals synchronized vagal nerve envelope in situ to implement Bio‐ES. It allows adaptive adjustment of intensity, frequency, and waveform of the Bio‐ES to fully meet personalized needs of tissue regeneration based on real‐time feedback from the vagal neural controlled organs. With this foundation, the Bio‐patch can effectively intervene with excessive fibrosis and microvascular stasis during the natural healing process by regulating the polarization time of macrophages, promoting the reconstruction of the tissue‐engineered structure, and accelerating the repair of damaged liver and kidney. This work develops a practical approach to realize biomimetic electronic modulation of the growth and development of soft organs only using a multifunctional Bio‐patch, which establishes a new paradigm for precise bioelectronic medicine.

AbstractPressure‐sensitive adhesives are widely utilized due to their instant and reversible adhesion to various dry substrates. Though offering intuitive and robust attachment of medical devices on skin, currently available clinical pressure‐sensitive adhesives do not attach to internal organs, mainly due to the presence of interfacial water on the tissue surface that acts as a barrier to adhesion. In this work, a pressure‐sensitive, repositionable bioadhesive (PSB) that adheres to internal organs by synergistically combining the characteristic viscoelastic properties of pressure‐sensitive adhesives and the interfacial behavior of hydrogel bioadhesives, is introduced. Composed of a viscoelastic copolymer, the PSB absorbs interfacial water to enable instant adhesion on wet internal organs, such as the heart and lungs, and removal after use without causing any tissue damage. The PSB's capabilities in diverse on‐demand surgical and analytical scenarios including tissue stabilization of soft organs and the integration of bioelectronic devices in rat and porcine models, are demonstrated.

AbstractHydrogel bioadhesives have emerged as a promising alternative to wound dressings for chronic wound management. However, many existing bioadhesives do not meet the functional requirements for efficient wound management through dynamically mechanical modulation, due to the reduced wound contractibility, frequent wound recurrence, incapability to actively adapt to external microenvironment variation, especially for those gradually‐expanded chronic wounds. Here, a self‐growing hydrogel bioadhesive (sGHB) patch that exhibits instant adhesion to biological tissues but also a gradual increase in mechanical strength and interfacial adhesive strength within a 120‐h application is presented. The gradually increased mechanics of the sGHB patch could effectively mitigate the stress concentration at the wound edge, and also resist the wound expansion at various stages, thus mechanically contracting the chronic wounds in a programmable manner. The self‐growing hydrogel patch demonstrated enhanced wound healing efficacy in a mouse diabetic wound model, by regulating the inflammatory response, promoting the faster re‐epithelialization and angiogenesis through mechanical modulation. Such kind of self‐growing hydrogel bioadhesives have potential clinical utility for a variety of wound management where dynamic mechanical modulation is indispensable.

AbstractQuinolines are ubiquitous heterocyclic aromatic scaffolds, which can be found in many natural and synthetic products. They are highly valued for their pharmacological and electrochemical properties, encouraging the discovery of new routes for quinoline synthesis and diversification. In particular, polyaryl‐substituted quinolines have recently surged as useful substrates for a wide variety of applications, yet their synthetic routes remain difficult and inefficient. Herein, we report a rapid and novel mechanochemical Friedländer synthesis of polyaryl‐substituted quinolines under basic conditions using ball milling. The optimized reaction conditions resulted in moderate to excellent yields ranging from 48% to >95% and demonstrated broad functional group tolerance at 1 hour reaction times. We further show a new route for the synthesis of photocatalyst DPQN2,4−di−OMe and photo‐ligand PPQN2,4−di−OMe as well as OLED donor‐acceptor pCzPPQ, electron transport material oligoquinoline TQB and organic semiconductor DPA. A gram scale reaction was also achieved using Resonant Acoustic Mixing (RAM), providing an isolated yield of 87% after a simple recrystallization in ethanol.

AbstractColorectal cancer (CRC) is the third most commonly diagnosed cancer and the second leading cause of cancer‐related death worldwide. More than 30% of CRC patients will experience treatment failure and tumor recurrence after standard‐of‐care treatment. Therefore, it is important to discover new therapeutic regimens for treating CRC. Repurposing existing clinically used drugs into new anticancer agents represents a feasible way and has become increasingly popular. In this study, the aim is to investigate the anticancer effect of sertraline on CRC and to elucidate its underlying mechanism. The data showed that sertraline exhibited a potent anticancer effect against CRC in vitro and in vivo. Sertraline inhibited Akt‐ and STAT3‐mediated cell proliferation but do not affect several programmed cell deaths in CRC, such as apoptosis, pyroptosis, ferroptosis, and mitophagy. Meanwhile, sertraline induced autophagosome accumulation but blocked autophagic flux in CRC cells. Further investigations reveal that sertraline impeded late autophagic flux at the stage of autolysosomal degradation rather than autophagosome‐lysosomal fusion in CRC. Furthermore, it is also demonstrated that sertraline synergistically sensitized chemotherapeutic agents against CRC. Overall, the study reveals the great potential of sertraline as a novel therapeutic candidate for CRC, which is worthy of further development in the future.

AbstractAs an alternative to thermionic X‐ray generators, cold‐cathode X‐ray tubes are being developed for portable and multichannel tomography. Field emission propagating from needle structures such as carbon nanotubes or Si tips currently dominates related research and development, but various obstacles prevent the widespread of this technology. An old but simple electron emission design is the planar tunnelling cathode using a metal–oxide–semiconductor (MOS) structure, which achieves narrow beam dispersion and low supplying voltage. Directly grown vertical graphene (VG) is employed as the gate electrode of MOS and tests its potential as a new emission source. The emission efficiency of the device is initially ≈1% because of unavoidable fabrication damage during the patterning processes; it drastically improves to >40% after ozone treatment. The resulting emission current obeys the Fowler–Nordheim tunnelling model, and the enhanced emission is attributed to the effective gate thickness reduction by ozone treatment. As a proof‐of‐concept experiment, a clustered array of 2140 cells is integrated into a system that provides mA‐class emission current for X‐ray generation. With pulsed digital excitations, X‐ray imaging of a chest phantom, demonstrating the feasibility of using a VG MOS electron emission source as a new and innovative X‐ray generator is realized.

AbstractAlkaline water electrolysis is the promising technical pathway of large‐scale green hydrogen production. However, its hydrogen evolution reaction (HER) is hindered by the alkaline environment, leading to slow H2O splitting kinetics, especially for NiMoCu alloy catalysts which are considered potential alkaline HER catalysts. In this work, the Ru‐substrate modified NiMoCu20 porous electrode is designed by a continuous multistep electrodeposition method. It shows the good alkaline HER performance at the high current density of 1000 mA cm−2, which is attributed to the synergistic charge‐reconfiguration effects between Ru‐substrate and NiMoCu alloy by density functional theory (DFT) calculations and in situ Raman spectra analysis. It indicates that the Ru‐substrate is capable of encouraging H‐OH* bond breakage and optimizing transition‐state H* adsorption. Further, the overall water electrolysis results of the alkaline water electrolysis cell (30 wt% KOH) at 70 °C show that it has good performance at the large current density of 1000 mA cm−2 with 2.05 V and good stability at 600 mA cm−2 up to 500 h. It provides the possibility of designing the high‐performance HER electrode from the view of industrial applications.

AbstractIn recent years, self‐assembled monolayers (SAMs) have been proven to work efficiently as hole‐selective materials in both organic solar cells (OSCs) and perovskite solar cells. Although competitive performances are reported with these materials, a mechanistic understanding on device stability remains elusive. This study reveals that while various SAM molecules can increase the indium tin oxide (ITO) work function versus vacuum, they may not consistently result in monolayers that ensure simultaneous improvement in performance and operational stability of devices. Energetically, achieving alignment between the work function of the SAM‐modified electrode and the ionization energy (IE) of the donor is shown to be crucial for a low hole injection barrier, irrespective of the SAM's IE. Light‐induced degradation in the widely used SAM, (2‐(9H‐carbazol‐9‐yl)ethyl) phosphonic acid (2PACz), is identified through diverse aging tests and comprehensive chemical and electronic characterizations. This degradation involves SAM molecule decomposition and chemical reactions with the photoactive layer, contributing further to device degradation. Addressing these challenges, sputtered nickel oxide/SAM bilayers are proposed as hole‐selective contact with tailored interface energetics for both efficient and photostable OSCs, offering a promising alternative to commonly used hygroscopic PEDOT:PSS in OSCs.

Published: August 2024

AbstractUrea electrosynthesis from co‐electrolysis of NO3− and CO2 (UENC) under ambient conditions is recognized as an appealing approach for effective and sustainable urea production, while it requires high‐efficiency UENC electrocatalysts to promote the C─N coupling and hydrogenation processes. Herein, single‐atom Cu anchored on MoS2 (Cu1‐MoS2) is explored as a highly active and selective UENC catalyst. Theoretical calculations and operando spectroscopic characterizations unveil the synergistic tandem catalysis of Cu1‐MoS2 for the UENC, where Cu single atoms trigger the early C─N coupling, while MoS2‐edges promote the key hydrogenation step of *CO2NH2 to *COOHNH2 for urea generation. Strikingly, Cu1‐MoS2 equipped in a flow cell achieves the excellent UENC performance with a maximum urea‐Faradaic efficiency of 57.02% at −0.6 V and the corresponding urea yield rate of 23.3 mmol h−1 g−1, surpassing nearly all previously reported UENC catalysts.

Published: August 2024

AbstractWe have developed a general model to predict CO2 equilibrium solubility in aqueous tertiary amine solutions by relating the equilibrium constant (K1) to all relevant parameters in a logical function form. Testing our model, we measured CO2 equilibrium solubility data for N‐methylmorpholine (NMM) and N‐ethylmorpholine (NEM) across various conditions. Comparison with six existing models reveals our general model's superior predictive performance not only for NMM and NEM but also for an additional 10 tertiary amine solutions from literature, indicating its universality. Comprehensively considering the CO2 equilibrium solubility, amine dissociation constant (pKa) and the CO2 absorption heat, it is found that NMM and NEM may be promising desorption promoters enabling to reduce the energy cost. In short, it is expected the general model can be applied to more other tertiary amine systems.

AbstractVisible‐light‐driven dual catalysis was employed to stereoselectively produce densely substituted cyclobutanes from Erlenmeyer‐Plöchl azlactones. The single‐step preparation of non‐natural amino acid dimers containing the cyclobutane moiety was achieved through a synergy between iridium photocatalysis and catalytic nickel(II) triflate as a Lewis acid. The desired 1,2‐(zeta)‐Z,E‐isomers were isolated in good yields and with high regio‐ and diastereoselectivity (in all cases, >19 : 1 d.r.). To the best of our knowledge, this is the first report of direct access to truxinic acid analogues using azlactones. Control experiments, EPR reaction monitoring, and DFT calculations suggest that the presence of a Lewis acid, combined with the use of powerful blue LEDs, plays a crucial role in the reactivity of this reaction.

AbstractA new approach of dual visible light‐induced gold(III)‐catalyzed alkynylation and its application in selective modification of alkyne‐linked peptides has been developed. The bis‐cyclometalated gold(III) complex exhibited dual roles of (1) in situ generation of quinolizinium‐based photosensitizer (λem=500 – 594 nm) and (2) alkynylation of iminium ions. Under optimized conditions, alkynylated products were afforded in good yields up to 73 %. The application of this strategy in selective modification of alkyne‐linked peptides gave modified peptides in up to 67 % conversion. Our dual visible light/gold(III) catalysis exemplifies the potential of merging photocatalysis and transition metal catalysis to develop novel bioconjugation.
