AbstractLanthanide neodymium (Nd)‐based nanocrystals exhibit exceptional near‐infrared II (NIR‐II) fluorescence imaging properties, like narrow and multi‐peak emissions, long luminescence lifetime, and good photostability. However, long‐term accumulation in the reticuloendothelial system restrains their clinical applications due to toxicity in vivo. Here, a biodegradable hollow virus‐like neodymium oxide (Nd2O3) Nd‐nanoprobe is presented that is modified with cyclic arginine‐glycine‐aspartic acid (cRGD) pentapeptide, showing remarkable cancer‐targeting ability and NIR‐II fluorescence imaging features. The nanoprobe is biodegraded to 4–6 nm Nd2O3 nanogranules in vivo, and the pharmacokinetics of the nanoprobe demonstrated its rapid urine excretion and negligible systematic toxicity. Moreover, this nanoprobe can accurately identify malignant lesions from normal tissues in xenograft and transgenic mice models and precisely navigate breast cancer surgery under NIR‐II imaging guidance. Taken together, this Nd2O3‐based nanoprobe enables real‐time, dynamic delineation and accurate resection of cancers guided by NIR‐II fluorescence imaging with great potential for future clinical translation during breast‐conservative surgery.

Published: January 2024

AbstractAs a photoinduced and electro‐induced phase change material, VO2 undergoes a transition from an insulating phase to a metallic phase under photoelectric stimulation, accompanied by strong lattice distortion and band changes. This characteristic of simultaneously responding to optical and electrical signals provides a basis for simulating biological vision systems, but the volatility of phase transition challenges the Long‐term memory of neural networks. Here, a phase transition‐regulated artificial photoelectric synapse based on VO2/graphene heterostructure is proposed. Graphene serves as an electron exchange center, amplifying weak signals generated by VO2 phase transitions and achieving nonvolatile properties. Using the energy band change of VO2 before and after the photoinduced phase transition and the electron exchange with graphene, synaptic devices can be regulated by optical signals. The modulation of gate voltage on the Fermi level of graphene leads to the phase transition of VO2, thereby achieving the regulation of synapses by electrical signals. Extract the electrical conductivity difference between two equivalent synapses as synaptic weight values to train a three‐layer neural network. The trained neural network achieves high recognition accuracy and noise resistance for handwritten digits, which is of great significance for the application of artificial optoelectronic synapses in neural morphology calculation.

AbstractWidening the voltage window of the nickel‐rich layered oxide cathode‐based lithium metal batteries (LMBs) can effectively improve the energy density of rechargeable batteries. However, serious safety issues associated with the high reactivity between LiNi0.8Co0.1Mn0.1O2 (NCM811) and electrolyte at high cut‐off voltage remains challenging. Herein, a flame‐retardant electrolyte with the ability to form a robust armor‐like electrode electrolyte interphase (EEI) with LiF and LixByOz compounds for stabilizing Li||NCM811 batteries is proposed. Such electrolyte exhibits the high thermal stability with flame‐retardant effect for ensuring the battery safety at high voltage. The armor‐like EEI can effectively protect both NCM811 and lithium (Li) for improving the battery cycling performance. As a result, the capacity retention rate of the NCM811 cathode with such electrolyte reached 68% after 150 cycles at 4.6 V. This work provides an effective reference for the reasonable design of high‐voltage, flame‐retardant electrolytes for LMBs.

AbstractThe realization of efficient large‐area perovskite solar cells stands as a pivotal milestone for propelling their future commercial viability. However, the upscaling fabrication of perovskite solar cells is hampered by efficiency losses, and the underlying growth mechanism remains enigmatic. Here, it is unveiled that a prevalent upscaling technology, namely blade‐coating, inherently triggers top‐down inhomogeneity strains, predominantly concentrated on the surface of wide‐bandgap perovskite films. Through strain mitigation strategies, the perovskite films exhibit reduced halide vacancies, leading to enhanced stability and improved optoelectronic characteristics. Consequently, the blade‐coated perovskite solar cells achieve minimal efficiency loss when transitioning from small‐area to large‐area devices, enabling the realization of 1 cm2‐area 1.77 eV‐bandgap cells with a remarkable efficiency of 18.71%. Additionally, the strain‐relieved device exhibits an exceptional 109% retention of its initial efficiency even after 400 h of continuous operation, in stark contrast to the control device which experiences a decline to 91%. Furthermore, the resulting 4‐terminal all‐perovskite tandem solar cells crafted utilizing blade‐coated 1.77 eV‐bandgap subcells achieve a maximum efficiency of 27.64% (stabilized at 27.28%). This study not only sheds light on the intricacies of upscaling preparation techniques but also overcomes potential obstacles that can impede the trajectory toward achieving large‐scale perovskite solar cells.

Published: January 2024

AbstractPotassium metal batteries coupling with high‐voltage manganese hexacyanoferrate (MnHCF) cathodes are promising candidates for energy storage devices. Ethers are the primary electrolyte solvent candidates for reversible potassium metal anodes, but their poor oxidative stability at high voltage restricts the application. Taking advantage of the steric hindrance, a dilute (1 m) non‐fluorinated ether with extended alkyl groups is designed to reduce the solvation capability to K ions, thus suppressing the solvent decomposition and tailoring the interphase composition on both cathode and anode sides. The accompanying high viscosity associated with the long alkyl groups can be readily resolved by incorporating an S‐containing additive, which further boosts the oxidative stability to 4.6 V. Furthermore, the additive contributes to the S‐rich organic species among the interphases that inhibit the metal dissolution of the cathode and induce the homogenous K deposition through promoted kinetics. Benefiting from the stable interphases and restricted side reactions, the dilute non‐fluorinated ether‐based electrolyte enables the stable cycling of MnHCF||K cell for over 200 cycles with a high Coulombic efficiency of over 99.4% under a negative/positive capacity ratio of 4.

AbstractDespite of urgent needs for highly stable and efficient electrochemical water‐splitting devices, it remains extremely challenging to acquire highly stable oxygen evolution reaction (OER) electrocatalysts under harsh industrial conditions. Here, a successful in situ synthesis of FeCoNiMnCr high‐entropy alloy (HEA) and high‐entropy oxide (HEO) heterocatalysts via a Cr‐induced spontaneous reconstruction strategy is reported, and it is demonstrated that they deliver excellent ultrastable OER electrocatalytic performance with a low overpotential of 320 mV at 500 mA cm−2 and a negligible activity loss after maintaining at 100 mA cm−2 for 240 h. Remarkably, the heterocatalyst holds outstanding long‐term stability under harsh industrial condition of 6 m KOH and 85 °C at a current density of as high as 500 mA cm−2 over 500 h. Density functional theory calculations reveal that the formation of the HEA‐HEO heterostructure can provide electroactive sites possessing robust valence states to guarantee long‐term stable OER process, leading to the enhancement of electroactivity. The findings of such highly stable OER heterocatalysts under industrial conditions offer a new perspective for designing and constructing efficient high‐entropy electrocatalysts for practical industrial water splitting.

AbstractThe development of efficient multi‐resonance thermally activated delayed fluorescence (MR‐TADF) materials with ultra‐narrowband emission presents an ongoing challenge. In this work, a carbazole‐fused dual‐boron embedded MR‐TADF framework is proposed, achieving three emitters, CFDBO, CFDBA, and CFDBCz, via one‐shot borylation with very high yields of over 70%. The emitters display ultra‐narrowband blue emission with peaks ranging from 452 to 479 nm and small full width at half maximum (FWHM) values of only 16–18 nm in dilute toluene solutions. Furthermore, the organic light‐emitting diode (OLED) incorporating CFDBO exhibits pure‐blue emission with a peak of 460 nm and Commission International de l'Eclairage coordinates of (0.14, 0.12). Meanwhile, OLEDs incorporating CFDBA/CFDBCz demonstrate remarkable performances with high external quantum efficiencies of 30.9%/32.4% and exceptionally slender FWHM values of 21/22 nm, representing outstanding performances among reported MR‐TADF materials.

AbstractPolysubstituted carbazoles were efficiently synthesized through direct benzannulation reaction between 1,4‐dicarbonyl compounds and indoles with catalytic amount of inexpensive zirconium(IV) chloride. This transformation proved to be regioselective and furnishes 1,4‐disubstituted and 1,2,4‐trisubstituted carbazoles with yields ranging from 26% to 91% and broad substrate scope. Moreover, this protocol benefits from using readily accessible starting materials without the need of their pre‐functionalization. The synthetic utility of the products was exemplified by functionalization of an iodocarbazole by means of Suzuki‐Miyaura reactions and by the synthesis of a 3‐deaza‐derivative of the natural product canthin‐6‐one.

AbstractRecycling metals from waste materials has become a major approach to metal resource utilization, with electronic waste (e‐waste) and waste catalysts being the most important recycling resources. Although traditional recovery technologies (pyrometallurgy and hydrometallurgy) have a recovery efficiency of up to 100%, they have disadvantages of high energy consumption, high cost, and strong corrosiveness. Most importantly, they cannot achieve selective leaching. To address these issues, some fusion technologies have been developed. Electrodeposition has significant advantages in separating and purifying each metal, but if applied on a large scale in industry, it requires higher energy consumption. While photocatalytic technology has low energy consumption but low selectivity, hence further exploration is needed. Metal‐organic frameworks (MOFs) materials have great selectivity for metal ions, which are environmentally friendly and efficient, and a promising new material. Some recently typical recovery methods for six valuable metals, platinum (Pt), gold (Au), silver (Ag), lithium (Li), nickel (Ni), and cobalt (Co) in e‐waste and industrial catalysts are reviewed. The advantages and disadvantages of each method as well as their impact on the leaching efficiency and selectivity of different metals are also compared, aiming to provide useful guidance for further continuously advancing the research on efficient, selective, environmentally friendly metal recycling in the future.

AbstractSpiking neural networks (SNNs) employ discrete spikes that mimic the firing of neurons in biological systems to process and transmit information. This characteristic enables SNNs to effectively capture temporal dynamics and capitalize on the time information inherent in time‐varying inputs, such as motion, audio/video streams, and other sequential data. Currently, most hardware implementations of SNNs are designed to use rate‐coding, where information is encoded in the rate of spikes. However, it still remains challenging for the hardware implementation of temporal coding in SNNs, which allows for higher input sparsity and exploits additional dimensions such as precise spike timing and relative spike timings. This study presents hardware implementations of SNNs constructed by organic electrochemical transistors (OECTs), processing temporal‐coded information. The protic dynamics in response to electrical stimuli enable the emulation of temporal integration, reset, and leaking of membrane potential in a simple leaky integrate‐and‐fire (LIF) neuron circuit. By utilizing these features, the emulated LIF neuron can be employed to construct SNNs capable of processing temporal‐coded information in complex tasks including coincidence detection and dynamic handwriting recognition, exhibiting high performance and good tolerance even when dealing with noisy datasets.

Published: January 2024

AbstractTriboelectric nanogenerators (TENGs) utilize the synergetic effect of triboelectrification and electrostatic induction to guide electrons through an external circuit, enabling low‐frequency mechanical and biomechanical energy harvesting and self‐powered sensing. Integrating 2D material with a high specific surface area into flexible ferroelectric polymers such as polyvinylidene difluoride (PVDF) has proven to be an efficient strategy to improve the performance of TENG devices. Scalable fabrication of graphene‐integrated PVDF nanocomposite fiber using thermal drawing process is demonstrated for the first time in this study. The open‐circuit voltage and short‐circuit current show 1.41 times and 1.48 times improvement with the integration of 5% graphene in the PVDF fibers, respectively. The TENG fabric shows a maximum power output of 32.14 µW at a matching load of 7 MΩ and a power density of 53.57 mW m−2. The fibers exhibit excellent stability in harsh environmental conditions such as alkaline medium, high/low temperature, multi‐washing cycle, and long‐time usage.

Published: January 2024

This article proposes a flexible surgical robot featuring strong magnetic steering achieved by a hemispherical magnet array actuation, and high‐accuracy ultrasonic position sensing achieved by a beacon total focusing method (b‐TFM). The hemispherical magnet array with magnetic focusing is described and its array parameters are optimized through finite element analysis to increase the magnetic field for actuation. The magnetic field strength at 100 mm for the array with the same mass as the cylindrical magnet is about 1.8 times higher than that of the cylindrical magnet. Using the magnet array actuation, the flexible robot exhibits the capability of agile steering to navigate along a predefined trajectory. In addition, a 1 mm × 1 mm lead zirconate titanate (PZT) patch is embedded into the tip of the flexible robot as a beacon for b‐TFM ultrasonic imaging to detect the position of the robot. Therefore, the entire navigation process can be executed under the supervision of the ultrasonic position sensing system, and the maximum error is 0.8 mm when the steering radius is 100 mm.

Published: January 2024

AbstractSomatic variants in the NOTCH pathway regulator FBXW7 are frequently seen in a variety of malignancies. Heterozygous loss‐of‐function germline variants in FBXW7 have recently been described as causative for a neurodevelopmental syndrome. Independently, FBXW7 was also considered as a susceptibility gene for Wilms tumor due to a few observations of heterozygous germline variants in patients with Wilms tumor. Whether the same FBXW7 variants are implicated in both, neurodevelopmental delay and Wilms tumor formation, remained unclear. By clinical testing, we now observed a patient with neurodevelopmental delay due to a de novo constitutional mosaic FBXW7 splice site pathogenic variant who developed Wilms tumor. In the tumor, we identified a second hit frameshift variant in FBXW7. Immunohistochemical staining was consistent with mosaic loss of FBXW7 protein expression in the tumor. Our data support the role of constitutional FBXW7 pathogenic variants in both, neurodevelopmental disorder and the etiology of Wilms tumor. Therefore, Wilms tumor screening should be considered in individuals with constitutional or germline pathogenic variants in FBXW7 and associated neurodevelopmental syndrome.

Published: January 2024

AbstractParticle emission from a Bose‐Einstein condensate with periodically modulated interactions is investigated in a 1D lattice. Within perturbative analysis, which leads to instabilities for discrete modes, the main regimes are obtained where the system can emit a large particle jet, and the distinctly intermittent rather than continuous emission is found. The time evolution of the trapped particles exhibits a stair‐like decay, and a larger drive induces a more significant intermittency. This study further sheds light on the dynamics of the stimulating process, and demonstrates that instead of a real suspension, the intermittency represents a build‐up stage of the system. The theoretical framework might be generalized to the explorations on multiple‐site systems with analogous configurations and couplings, and offer new insights into other fundamental nonequilibrium problems.

AbstractPolypeptides, as natural polyelectrolytes, are assembled into tailored proteins to integrate chromophores and catalytic sites for photosynthesis. Mimicking nature to create the water‐soluble nanoassemblies from synthetic polyelectrolytes and photocatalytic molecular species for artificial photosynthesis is still rare. Here, we report the enhancement of the full‐spectrum solar‐light‐driven H2 production within a supramolecular system built by the co‐assembly of anionic metalloporphyrins with cationic polyelectrolytes in water. This supramolecular photocatalytic system achieves a H2 production rate of 793 and 685 μmol h−1 g−1 over 24 h with a combination of Mg or Zn porphyrin as photosensitizers and Cu porphyrin as a catalyst, which is more than 23 times higher than that of free molecular controls. With a photosensitizer to catalyst ratio of 10000 : 1, the highest H2 production rate of >51,700 μmol h−1 g−1 with a turnover number (TON) of >1,290 per molecular catalyst was achieved over 24 h irradiation. The hierarchical self‐assembly not only enhances photostability through forming ordered stackings of the metalloporphyrins but also facilitates both energy and electron transfer from antenna molecules to catalysts, and therefore promotes the photocatalysis. This study provides structural and mechanistic insights into the self‐assembly enhanced photostability and catalytic performance of supramolecular photocatalytic systems.

Published: January 2024

AbstractHigh‐energy Li metal batteries (LMBs) consisting of Li metal anodes and high‐voltage cathodes are promising candidates of the next generation energy‐storage systems owing to their ultrahigh energy density. However, it is still challenging to develop high‐voltage nonflammable electrolytes with superior anode and cathode compatibility for LMBs. Here, we propose an active diluent‐anion synergy strategy to achieve outstanding compatibility with Li metal anodes and high‐voltage cathodes by using 1,2‐difluorobenzene (DFB) with high activity for yielding LiF as an active diluent to regulate nonflammable dimethylacetamide (DMAC)‐based localized high concentration electrolyte (LHCE‐DFB). DFB and bis(fluorosulfonyl)imide (FSI−) anion cooperate to construct robust LiF‐rich solid electrolyte interphase (SEI) and cathode electrolyte interphase (CEI), which effectively stabilize DMAC from intrinsic reactions with Li metal anode and enhance the interfacial stability of the Li metal anodes and LiNi0.8Co0.1Mn0.1O2 (NCM811) cathodes. LHCE‐DFB enables ultrahigh Coulombic efficiency (98.7 %), dendrite‐free, extremely stable and long‐term cycling of Li metal anodes in Li || Cu cells and Li || Li cells. The fabricated NCM811 || Li cells with LHCE‐DFB display remarkably enhanced long‐term cycling stability and excellent rate capability. This work provides a promising active diluent‐anion synergy strategy for designing high‐voltage electrolytes for high‐energy batteries.
