Published: January 2025

AbstractThe development of multi‐action pesticides presents significant advantages, including cost‐effectiveness, reduced application frequency, enhanced resistance management, and minimized environmental impact. Despite its efficacy in targeting chitin synthase in both fungi and insects, the insecticidal performance of polyoxin B remains limited. To overcome this limitation, a novel nano‐formulation, polyoxin B@ZTS is developed, utilizing agricultural byproducts, tea saponin, and zein. This formulation features a small particle size, high leaf deposition efficiency, and excellent dispersion properties. Leveraging a disulfide bond system, polyoxin B@ZTS is designed to respond to the intracellular reducing environment, enabling controlled release of polyoxin B. Remarkably, the nano‐formulation facilitates the penetration of physiological barriers, achieving equivalent insecticidal and fungicidal efficacy to polyoxin B at only one‐fifth of the dosage. This work highlights the potential of eco‐friendly, cost‐effective, and multifunctional nano‐pesticides, providing a compelling solution for sustainable agricultural practices and demonstrating broad applicability in integrated pest and disease management.

AbstractInterface modification with the ability to passivate defects and regulate interface energy level is an important method to maximize the photovoltaic performance of perovskite solar cells (PSCs). Herein, through modifying the interface between perovskite and hole transport layer via different alkylammonium acetate ionic liquid molecules with varied dipole moments, efficient and stable PSCs are achieved. Especially, hexylammonium acetate (HAAc) with high dipole moment can reduce the energy difference between perovskite and hole transport layer to facilitate hole extraction and reduce energy loss. In addition, HAAc has a strong chemical binding ability to both acceptor and donor defects on perovskite surfaces through synergistic passivation of HA+ cation and Ac− anion, thereby reducing defect‐assisted recombination. The combined effects of energy level modulation and defect suppression lead to an overall enhancement in device performance. The best HAAc‐passivated device reaches an efficiency of up to 25.06% and maintains > 97.30% initial efficiency for 1000 h in air with 30 ± 10% humidity. In addition, the flexible perovskite solar cells exhibit excellent mechanical stability, with efficiency remaining above 71% of the initial value after 10 000 bending cycles at a small bending radius of 5 mm.

AbstractNeural biointerfacing, enabling direct communication between neural systems and external devices, holds great promises for applications in brain machine interfaces, neural prosthetics, and neuromodulation. However, current neural electronics made of conventional rigid materials are challenged by their inherent mechanical mismatch with the neural tissues. Hydrogel bioelectronics, with mechanical properties compatible with the neural tissues, represent an alternative to these limitations and enable the next‐generation neural biointerfacing technology. Here, an overview of cutting‐edge research on conducting hydrogels (CHs) bioelectronics for neural biointerfacing development, emphasizing material design principles, manufacturing techniques, essential requirements, and their corresponding application scenarios is presented. Future challenges and potential directions regarding CHs‐based neural biointerfacing technologies, including long‐term reliability, multimodal hydrogel bioelectronics for closed‐loop system and wireless power supply system, are raised. It is believed that this review will serve as a valuable resource for further advancement and implementation of next‐generation neural biointerfacing technology.

AbstractThumb actions, outperforming conventional methods such as hand gestures or wrist gestures in terms of dexterity, agility and intuitiveness, have long been sought‐after for achieving immersive interactive experiences in robotic control and AR/VR platforms. However, accurate mapping of such dynamic, subtle thumb actions remains a difficult challenging. Here, a wireless, wrist‐affixed soft ultra‐conformal neuromuscular interface system (UniSyst) is reported to capture high‐fidelity surface electromyography crucial for decoding dynamic subtle thumb actions. The UniSyst, which can be easily fabricated at scale and in mass quantities, features a 16‐channel soft, stretchable sensing array for broad, high‐resolution data capture and a stiff design for plug‐and‐play interface with external rigid wireless acquisition module. This soft‐stiff design ensures consistent electrode‐skin contact under substantial skin deformations, thus avoiding undesired motion artifacts commonly observed with rigid alternatives. Facilitated with a lightweight 1D convolution neural network deep learning classifier, this system shows remarkable recognition accuracy over that of traditional forearm placements, fairly compared through concurrently collected signals from the wrist and the forearm of 12 participants. In practical scenarios, the soft UniSyst exhibits rapid, precise thumb‐controlled interactive capabilities, adeptly managing human–machine communications in both digital platforms and immersive gaming controls.

AbstractBone regeneration is synergistically regulated by growth factors, which are expressed in a coordinated cascade of events. An ideal guided bone regeneration membrane (GBRM) shall present barrier and antibacterial functions, and promote osteogenesis through time‐controlled release of growth factors. In this study, a coordinated cascade therapy‐based Janus fibrous membrane is fabricated by coaxial electrospinning and layer‐by‐layer self‐assembly technology (LBL). Specifically, the oriented PCL/PLGA fibers loaded with zinc oxide nanoparticles (ZnO NPs) are designed as the outer layer, and randomly arranged core‐shell Gelatin/PLLA nanofibers are employed as the inner layer to rapidly release aFGF and sustainedly release BMP‐2. Results demonstrated that the Janus fibrous membrane achieved multiple functions to satisfy essential requirement of bone regeneration, which exhibited remarkable antibacterial ability, barrier function, osteoinductive ability. Interestingly, the significant enhancement of oxidative phosphorylation (OXPHOS) as the major energy supply pathway is the decisive factor to drive osteogenic differentiation of BMSCs induced by Janus fibrous membranes. This study provides a novel strategy to fabricate multifunctional membranes/scaffolds, displaying great potential applications in tissue engineering. Besides, understanding the synergistic mechanism of time‐controlled release of growth factors on the cellular energy metabolism process can provide deeper insights into growth factors‐mediated tissue regeneration and optimizing healing outcomes.

AbstractMolybdenum diselenide (MoSe2), a promising anode material for potassium‐ion batteries (KIBs), often suffers from sluggish kinetics, substantial volumetric expansion, and dissolution and shuttling of intermediate phases, resulting in unsatisfactory cycle stability and rate performance. In this work, a dual‐defect MoSe2 (equipped with interlayer defects and Se vacancies) is introduced by a novel plasma‐induced etching process, encapsulated in nitrogen‐doped porous carbon nanofibers (denoted as dd‐MoSe2‐x@NC). These modifications create multidimensional potassium‐ion insertion channels, improve ion transfer dynamics, enhance intrinsic conductivity, and expose more reactive sites. Moreover, the nitrogen‐doped porous carbon matrix mitigates volumetric expansion and suppresses potassium‐polyselenide (K‐pSex) dissolution and shuttling through a physicochemical dual‐anchoring strategy. The dd‐MoSe2‐x@NC electrode demonstrates remarkable electrochemical performance, achieving a high specific capacity of 418.5 mAh g−1 at 0.05 A g−1, reliable cycling stability over 1400 cycles at 2.0 A g−1, and superior rate performance with 125.0 mAh g−1 at 10.0 A g−1. The findings elucidate the “intercalation‐conversion” reaction mechanism and show that the dd‐MoSe2‐x@NC//PTCDA full cell attains high energy density (115.8 W h kg−1) and high power density (1057.2 W kg−1). This work highlights the enhanced potassium storage kinetics and cycling stability of layered transition metal chalcogenides, demonstrating the potential of MoSe2 in high‐performance KIBs.

AbstractBreaking the thermal, mechanical and lightweight performance limit of aerogels has pivotal significance on thermal protection, new energy utilization, high‐temperature catalysis, structural engineering, and physics, but is severely limited by the serious discrete characteristics between grain boundary and nano‐units interfaces. Herein, a thermodynamically driven surface reaction and confined crystallization process is reported to synthesize a centimeter‐scale supercontinuous ZrO2 nanolayer on ZrO2‐SiO2 fiber aerogel surface, which significantly improved its thermal and mechanical properties with density almost unchanged (≈26 mg cm−3). Systematic structure analysis confirms that the supercontinuous layer achieves a close connection between grains and fibers through Zr─O─Si bonds. The as‐prepared aerogel exhibits record‐breaking specific strength (≈84615 N m kg−1, can support up to ≈227 272 times aerogel mass) and dynamic impact resistance (withstanding impacts up to 500 times aerogel mass and up to 200 cycling stability at 80% strain). Besides, its temperature resistance has also been greatly optimized (400 °C enhancement, stability at 1500 °C). This work will provide a new perspective for exploring the limits of lightweight, high strength, and thermal properties of solid materials.

Published: January 2025

AbstractBlue is one of the three primary colors, and it is a crucial element in the regulation and application of organic room‐temperature phosphorescence (ORTP). However, the considerable Stokes shift of small organic molecules presents a challenge for creating blue afterglow materials. To address this, host‐guest‐doped materials are prepared by selecting compounds with similar structures for self‐doping. This method effectively regulated blue organic long‐lasting phosphorescence. Additionally, the persistent‐RTP and organic long‐persistent luminescence (LPL) properties can be further enhanced by incorporating a rigid or flexible polymer network, creating a dense environment between the host and guest. Remarkably, the phosphorescence lifetime and afterglow duration of polymer‐assisted doped materials are ≈5 times greater than those of host‐guest doped crystal materials. Apart from its high efficiency, environmental friendliness, and easy synthesis, this blue ORTP material boasts high thermal stability and flexibility. Furthermore, this blue material demonstrates considerable potential in applications such as information encryption and anti‐counterfeiting across various media, including paper, cotton thread, and leaves.

AbstractIn this study, PAP‐1‐Ch is presented, a novel anthracene‐based host material, designed specifically for high‐efficiency and stable blue fluorescent organic light‐emitting diodes (OLEDs). The unique molecular architecture of PAP‐1‐Ch integrates a chrysene substituent of anthracene, achieving an optimal balance between steric hindrance and molecular linearity. This balance plays a critical role in minimizing π–π stacking, which effectively prevents fluorescence quenching while promoting favorable horizontal molecular orientation of up to 91.5% and enhancing the photoluminescence quantum yield (PLQY) up to 93.1%, thereby significantly improving the out‐coupling efficiency. Furthermore, the finely tuned structure of PAP‐1‐Ch results in superior charge carrier mobility and a more balanced electron/hole injection current. Devices fabricated with PAP‐1‐Ch as the host material demonstrated remarkable performance metrics, achieving blue color purity with Commission Internationale de l'Eclairage (CIE) coordinates of (0.136, 0.130), a luminance efficiency of 13.2 cd A−1, a maximum external quantum efficiency (EQE) of 12.6%, and an operational lifetime (LT95) of over 12 000 h at 100 cd m−2. These results represent a substantial advancement in the development of high‐efficiency, stable blue fluorescent OLEDs, paving the way for their application in next generation of high‐end displays.

AbstractIncoherent photon upconversion (UC) mediated by triplet‐triplet annihilation (TTA) offers multiple implementation pathways, from bio‐related applications to energy harvesting in photovoltaics. Despite its potential, TTA‐UC efficiency in the near‐infrared (NIR) range is notably low, particularly in solid‐state systems. Rubrene (Rub), a key annihilator in this spectral range, faces significant concentration quenching, primarily due to singlet fission (SF). To mitigate this issue, herein, the cyano (CN) functionalization of Rub is explored to reduce SF and boost solid‐state UC performance. By systematically increasing the number of CN groups, the modified Rub is examined in both solution and solid‐state environments, benchmarking it against unmodified Rub and assessing each energy transfer step. The findings reveal that CN modification, while detrimental to UC efficiency in solution, markedly improves solid‐state UC performance. Specifically, Rub functionalized with two peripheral CN groups achieves a UC quantum yield (ΦUC) of 3.0% (out of a theoretical maximum of 50%) in the solid‐state–nearly tripling the maximum yield achieved with unmodified Rub. This advancement not only presents a more efficient and stable alternative to conventional Rub annihilators but also highlights the potential of CN‐tuning for enhancing other NIR annihilators in the solid state.

AbstractThis work presents a simple strategy to develop a new series of through‐space charge‐transfer (TSCT) donor–acceptor luminogens with varying alkyl chain lengths as spacer groups (D‐σ‐A), CznDPy [5‐(4‐(9H‐carbazol‐9‐yl) alkyl)‐5H‐pyrazino[2,3‐b] indole‐2,3‐dicarbonitrile] (n = 2, 3, 4, and 5) displaying rare multifunctional optical behaviors of aggregation‐induced emission (AIE), thermally activated delayed fluorescence (TADF), aggregation‐induced delayed fluorescence (AIDF), mechanoluminescence (ML), and mechanochromism (MCL) properties. Fine‐tuning the flexible chain lengths between donor and acceptor results in variable intermolecular interactions and charge transfer (CT) behavior, thereby modulating their respective optical properties in aggregated/solid states. The integrated emitters exhibit a maximum total quantum yield of 85% with a prolonged lifetime of 344 µs. Considering the challenges existing for developing AIDF molecules with longer lifetimes, enhanced fluorescence efficiency, and tunable emission characteristics, their utility is emphasized for efficient long‐term bioimaging of human breast cancer cells up to 7 days. These molecules constitute the first examples of multifunctional organic TSCT AIDF small molecules with such long lifetimes, tunable emission colors, and higher fluorescence efficiency used for the diagnostic imaging of cancer cells. This study also sheds light on the structure‐property relationships and offers valuable insights into the new class of tailored optical materials for various applications.

Peptide‐based bioinspired materials exhibit a variety of supramolecular morphologies and have the potential to function as organic semiconductors. Such biologically or naturally derived peptides with intrinsic semiconducting characteristics create new opportunities for sustainable biomolecule‐based optoelectronics devices. Affably, halide perovskite nanocrystals are emerging as potentially attractive nano‐electronic analogs, in this vein creating synergies and probing peptide‐perovskite‐based bio‐electronics are of paramount interest. The physical properties and inherent aromatic short‐peptide assemblies that can stabilize, and passivate the defects at surfaces assist in improving the charge transport in halide perovskite devices. This review sheds light on how these peptide‐perovskite nano‐assemblies can be developed for optical sensing, optoelectronics, and imaging for biomedical and healthcare applications. The charge transfer mechanism in peptides along with as an outlook the electron transfer mechanism between perovskite and short peptide chains, which is paramount to facilitate their entry into molecular electronics is discussed.

AbstractCapacitive dielectric temperature sensors based on polydimethylsiloxane (PDMS) loaded with 10 vol% of inexpensive, commercially‐available conductive fillers including copper, graphite, and milled carbon fiber (PDMS‐CF) powders are reported. The sensors are tested in the range of 20–110 °C and from 0.5 to 200 MHz, with enhanced sensitivity from 20 to 60 °C, and a relative response of 85.5% at 200 MHz for PDMS‐CF capacitors. PDMS‐CF capacitors are interrogated as a sensing element in wirelessly coupled chipless resonant coils tuned to 6.78 MHz with a response in the resonant frequency (fr) of the sensor, demonstrating an average sensitivity of 0.38% °C−1, a 40x improvement over a pristine PDMS capacitive sensor and outperforms state‐of‐the‐art frequency‐domain radio frequency temperature sensors. Exploiting its high sensitivity, the wireless sensing platform is interrogated using a low‐cost, portable, and open‐source NanoVNA demonstrating a relative response in fr of 48.5%, good agreement with instrumentation‐grade vector network analyzers (VNAs) and negligible change in performance at a range of reading distances and humidities. Finally, a wireless tag is demonstrated with rapid, reversible dynamic response to changes in temperature, as well as the in the first scalable, multiplexed array of chipless sensors for spatial temperature detection.

Published: January 2025

AbstractCherenkov radiation (CR) is a fascinating phenomenon that occurs not only in electromagnetic (EM) waves but also in water waves. The V‐shaped wake formed by a moving object on the water surface results from the constructive interference of water waves of different wavelengths, similar to CR. We designed and fabricated a one‐dimensional (1D) water wave crystal to analogize the behavior of moving particles in water waves. This crystal exhibits a band structure with both positive (positive group velocity) and negative slopes (negative group velocity), exciting and directing the water waves to produce forward and backward radiating wakes through a mechanism similar to CR. Notably, the radiation angle is easily adjustable. This method of regulating water wave wakes holds potential applications in scattering cancellation‐based wake stealth, navigation technology, and fluid dynamics for future offshore vessels.
