AbstractThe performance of aqueous zinc‐ion batteries (AZIBs) at high temperatures (HT) is severely compromised by active water corrosion, parasitic reactions, and dendrite growth. Herein, zinc trifluoroacetate is introduced at a low concentration (0.2 m), dissolved in triethyl phosphate (TEP) and H2O. The active water is suppressed due to the reconstructed original hydrogen bond network, which helps inhibit parasitic reactions and severe corrosion. Meanwhile, a solid electrolyte interphase (SEI) formed on the zinc anode due to the decomposition of the introduced zinc salt. The high‐tolerance SEI physically separates the electrolyte and anode, reducing the corrosion caused by active water. Moreover, TEP, as a prevalent fire‐retardant cosolvent, can preferentially anchor on the zinc sheet, serving as a shielding buffer layer. TEP is not only reconstructing the structure of the electric double layer (EDL), decreasing the content of active water, but also accelerating the prompt formation of SEI further. As proof of this synergistic effect, the assembled symmetric Zn‖Zn cells sustain to 700 h under the condition of 0.5 mA cm−2, and the Zn‖NH4V4O10 (NVO) full cells achieve 1400 cycles at 1 A g−1 at 60 °C. This work offers a promising solution to prompt the commercialization of AZIBs at HT.

AbstractCancer cells engage in active aerobic glycolysis to meet their bioenergetic synthesis needs, which is known as the Warburg effect. Such a process leads to lactate accumulation in the tumor microenvironment (TME), further promoting cancer progression and inducing immunosuppression. Herein, functionalized dendrimer‐Cu(II) complexes (for short, D‐Cu(II)) as a nanocarrier, which enables a Fenton‐like reaction is developed to generate a large amount of hydroxyl radicals and shows a T1‐weighted magnetic resonance (MR) imaging performance. Importantly, the D‐Cu(II) allows efficient delivery of lactate oxidase (LOx) to cancer cells, directly downregulating the lactate levels. When combining with an immune activator of leukadherin‐1, the developed D‐Cu(II)/LOx complexes alleviate the symptoms of mouse leukemia. With a further coating of macrophage membranes, the generated D‐Cu(II)/LOx@M allows for effective blood‐brain barrier crossing to treat an orthotopic murine glioma model under the guidance of Cu(II)‐facilitated MR imaging. By integrating the LOx‐mediated lactate depletion with Cu(II)‐mediated chemodynamic therapy, the developed dendrimer nanomedicines improve the overall survival and antitumor immune responses of mice, and help to remodel the immunosuppressive TME in both cancer models, greatly sensitizing the treatment efficacy of immune activator. Such dendrimer technology may further be used for theranostics of other cancer types through lactate depletion‐enhanced combinational therapy.

AbstractCharacterization of electromagnetic wave polarization states is critical in various applications of materials, biomedical, and imaging. The emergence of metasurfaces opens up the possibility of implementing highly integrated full‐Stokes imagers. Despite rapid development, prevailing schemes on metasurface‐based full‐Stokes imagers require interleaved or cascaded designs, inevitably resulting in performance deterioration, bulky size, and complicating the imaging procedure due to misalignment. To overcome these challenges, a non‐interleaved shared‐aperture full‐Stokes metalens enabled by the prior‐knowledge‐driven inverse design methodology is proposed. The metalens can be directly deployed into imagers, performing high‐accuracy diffraction‐limited full‐Stokes imaging without other ancillary components, breaking intrinsic constraints of efficiency and resolution in interleaved design. To demonstrate this, the metalens is integrated into the W‐band passive imaging system, as an alternative solution, to perform polarimetric imaging, which reduces the reliance on the high cost and high complexity of the ortho‐mode transducer and broadband correlator in traditional polarimetric radiometers. Furthermore, with the assistance of a 3D reconstruction method, the feasibility of multi‐polarization information for contactless surface slope measurements is explored. This work may open new paradigms for the full‐Stokes imager designing and broaden the applications of metasurface polarimetric imaging.

AbstractThe shift toward sustainable energy has fueled the development of advanced electrocatalysts to enable green fuel production and chemical synthesis. To date, no material outperforms Pt‐group catalysts for key electrocatalytic reactions, necessitating advanced catalysts that minimize use of these rare and expensive constituents (i.e., Pt) to reduce cost without sacrificing activity. Whilst a myriad of routes involving co‐synthesis of Pt with other elements have been reported, the Pt is often buried within the bulk of the composite, rendering a large proportion of it inaccessible to the interfacial electrocatalytic reaction. Surface decoration of Pt on arbitrary substrates is therefore desirable to maximize catalytic activity; nevertheless, Pt electrodeposition suffers from clustering and ripening effects that result in large () aggregates that hinder electrocatalytic activity. Herein, an unconventional synthesis method is reported that utilizes high‐frequency (10 MHz) acoustic waves to electrochemically ‘season’ a gold working electrode with an ultralow loading of Pt nanoclusters. The UNLEASH platform is shown to facilitate high‐density dispersion of nanometer‐order clusters at the bimetallic interface to enable superior atomic utilization of Pt. This is exemplified by its utility for methanol oxidation reaction (MOR), wherein a mass activity of 5.28 A is obtained, outperforming all other Au/Pt bimetallic electrocatalysts reported to date.

AbstractSince the initial discovery of 2D van der Waals (vdW) materials, significant effort has been made to incorporate the three properties of magnetism, band structure topology, and strong electron correlations—to leverage emergent quantum phenomena and expand their potential applications. However, the discovery of a single vdW material that intrinsically hosts all three ingredients has remained an outstanding challenge. Here, the discovery of a Kondo‐interacting topological antiferromagnet is reported in the vdW 5f electron system UOTe. It has a high antiferromagnetic (AFM) transition temperature of 150 K, with a unique AFM configuration that breaks the combined parity and time reversal (PT) symmetry in an even number of layers while maintaining zero net magnetic moment. This angle‐resolved photoemission spectroscopy (ARPES) measurements reveal Dirac bands near the Fermi level, which combined with the theoretical calculations demonstrate UOTe as an AFM Dirac semimetal. Within the AFM order, the presence of the Kondo interaction is observed, as evidenced by the emergence of a 5f flat band near the Fermi level below 100 K and hybridization between the Kondo band and the Dirac band. The density functional theory calculations in its bilayer form predict UOTe as a rare example of a fully‐compensated AFM Chern insulator.

AbstractOrganic semiconductors, characterized by their exceptionally long spin relaxation times (≈ms) and unique spinterface effects, are considered game‐changers in spintronics. However, achieving high‐performance and wide‐range tunable magnetoresistance (MR) in organic spintronic devices remains challenging, severely limiting the development of organic spintronics. This work combines straintronic multiferroic heterostructures with organic spin valve (OSV) to develop a three‐terminal OSV device with a gate structure. The device exhibits a record‐high MR ratio of 281% which 10 times higher than the average in polymer systems. More importantly, this work can perform multilevel writing operations on the device using gate voltages and create at least 10 stable spin‐dependent working states within a single device. Both experiments and theoretical calculations confirm such an extraordinary tunability range originates from the synergistic effects of strain and charge accumulation that amplified by the spinterface. This study demonstrates the potential of OSV systems for efficient spin manipulation and highlights the spinterface as an ideal platform for amplifying spin effects for next‐generation spintronic devices.

AbstractGa‐doped zinc oxide (ZnO) microwires hold great promise for developing highly efficient light sources because of the wide bandgap with proper exciton binding energy. However, most microwires grown from one mainstream approach, i.e., chemical vapor deposition (CVD), are morphologically and crystallographically defective, exhibiting limited photoluminescence performances. Herein, a simple and effective X‐ray irradiation strategy is demonstrated for enhancing the photoluminescence of Ga‐doped ZnO microwire in ambient conditions. Under moderate doses (≤ 150 Gy), the photoluminescence monotonically rockets up with X‐ray dose increment and achieves nine‐fold enhancement at a dose of ≈150 Gy, recording high photoluminescence improvement of ZnO microwires to date. The elemental characteristics under different controlled irradiation atmospheres suggest the elimination of surface oxygen vacancy and the cross‐section transmission electron microscope reveals prominent lattice relaxations after mild X‐ray irradiation. In addition, the X‐ray irradiated microwires further exhibit elevated electroluminescence by over three times. The enhanced photoluminescence and electroluminescence as well as long‐term stability enable us to imagine the super‐rapid applications of ZnO microwires in modern optoelectronic devices.

AbstractImmunotherapy holds potential as a treatment for gastric cancer (GC), though immune checkpoint inhibitor (ICI) resistance remains an obstacle. One resistance mechanism involves defects in interferon‐γ (IFN‐γ) signaling, in which IFN‐γ is linked to improved responsiveness to ICIs. Herein, the roles of RNA N6‐methyladenosine (m6A) modifications in regulation of IFN‐γ signaling and the responsiveness to ICIs are unveiled. The m6A‐binding protein YTH N6‐methyladenosine RNA‐binding protein F1 (YTHDF1) is overexpressed in GC tissues, correlating with the suppression of cancer immunity and poorer survival rates. YTHDF1 overexpression impaired the responsiveness to IFN‐γ in GC cells, and knockdown studies indicated the redundant effects of YTHDF2 and YTHDF3 with YTHDF1 in IFN‐γ responsiveness. RNA immunoprecipitation sequencing revealed YTHDFs directly target interferon regulatory factor 1 (IRF1) mRNA, a master regulator of IFN‐γ signaling, leading to reduced RNA stability and consequent downregulation of IFN‐γ signaling. Furthermore, in mouse syngeneic tumor models, Ythdf1 depletion in cancer cells resulted in reduced tumor growth and increased tumor‐infiltrating lymphocytes, which are attributed to the augmentation of IFN‐γ signaling. Collectively, these findings highlight how YTHDFs modulate cancer immunity by influencing IFN‐γ signaling through IRF1 regulation, suggesting their viability as therapeutic targets in cancer immunotherapy.

AbstractHuman hands can envelop the surface of an object and recognize its shape through touch. However, existing stretchable haptic sensors exhibit limited flexibility and stability to detect pressure during deformation, while also solely achieving recognition of planar objects. Inspired by the structure of skin tissue, an embedded construction‐enabled liquid metal‐based e‐skin composed of a liquid metal microstructured electrode (LM‐ME) array is fabricated for curved pressure mapping. The embedded LM‐ME‐based sensor elements are fabricated by using femtosecond laser‐induced micro/nanostructures and water/hydrogel assisted patterning method, which enables high sensitivity (7.42 kPa−1 in the range of 0–0.1 kPa) and high stability through an interlinked support isolation structure for the sensor units. The sensor array with a high interfacial toughness of 1328 J m−2 can maintain pressure sensation under bending and stretching conditions. Additionally, the embedded construction and laser‐induced bumps effectively reduce crosstalk from 58 to 7.8% compared to conventional flexible sensors with shared surfaces. The stretchable and mechanically stable sensor arrays possess shape‐adaptability that enables pressure mapping on non‐flat surfaces, which has great potential for object recognition in robotic skins and human‐computer interaction.

AbstractOrganic Electronic platforms for biosensing are being demonstrated at a fast pace, especially in healthcare applications where the use of organic (semi‐)conductive materials leads to devices that efficiently interface living matter. Nevertheless, interesting properties of organic (semi‐)conductors are usually neglected in the development of (bio‐)sensors. Among these, the non‐linear response when operated under dynamic biasing conditions (i.e., with pulsed driving voltages), thus mimicking synaptic plasticity phenomena, offers promising and largely unexplored possibilities for bio‐sensing. The artificial synaptic response's figures of merit reflect the composition of the surrounding environment and, ultimately, the ion concentration and dynamics at the organic (semi‐)conductor/electrolyte interface. Therefore, new sensing strategies that rely on the effect of target analytes on the short‐term plasticity response of Organic Neuromorphic Devices are being demonstrated. This work presents the development of a label‐free Single Electrode Neuromorphic Device (SEND) specifically designed for in vivo real‐time mapping of dopamine concentration. The device response is investigated as a function of the driving frequency, resulting in the determination of the optimal operational configuration for minimally invasive neuromorphic devices. It exhibits stable multi‐parametric response in complex fluids, in brain's mechanical models and in vivo, enabling monitoring of local variations of dopamine concentration in the rat brain.

AbstractBiomass gasification for syngas production is a key operating unit in the biomass utilization process. However, its overall efficiency and stability are often restricted by the presence of complex impurities, including particulate matters (PMs) and tars. In this study, a highly integrated ceramic membrane‐based reactor was developed for high‐temperature syngas cleaning, enabling the efficient in situ removal of PMs and tars from bio‐vapors produced by biomass gasification. Specifically, a silicon carbide (SiC) membrane could separate PMs from biomass volatiles in situ, while a structured Ni15La5/S1‐SiC catalyst (nickel and lanthanum‐laden silicalite‐1 zeolite supported on SiC foam) facilitated the catalytic reforming of tars. Compared to other control reactors (i.e., those containing either a membrane or catalyst alone), the integrated reactor showed synergistic intensification in producing clean syngas from biomass gasification, achieving PM and tar removal efficiencies of up to ~97% and ~90%, and exhibited excellent stability in five‐cycle evaluations at 800°C.

AbstractWe present a novel approach to achieve spatial variations in the degree of non‐covalent functionalization of twisted bilayer graphene (tBLG). The tBLG with twist angles varying between ~5° and 7° was non‐covalently functionalized with 1,4,5,8,9,11‐hexaazatriphenylenehexacarbonitrile (HATCN) molecules. Our results show a correlation between the degree of functionalization and the twist angle of tBLG. This correlation was determined through Raman spectroscopy, where areas with larger twist angles exhibited a lower HATCN peak intensity compared to areas with smaller twist angles. We suggest that the HATCN adsorption follows the moiré pattern of tBLG by avoiding AA‐stacked areas and attach predominantly to areas with a local AB‐stacking order of tBLG, forming an overall ABA‐stacking configuration. This is supported by density functional theory (DFT) calculations. Our work highlights the role of the moiré lattice in controlling the non‐covalent functionalization of tBLG. Our approach can be generalized for designing nanoscale patterns on two‐dimensional (2D) materials using moiré structures as a template. This could facilitate the fabrication of nanoscale devices with locally controlled varying chemical functionality.

AbstractThe bistability of multiple physical properties driven by external stimuli in a solid is a desired prerequisite for its application in memory devices with convenient data readout. We present a pathway for thermal bistability detectable in four physical properties: magnetic, light absorption, second‐harmonic generation (SHG), and dielectric. We report a novel heterometallic (TBA){[FeII(phIN)4][ReV(CN)8]} ⋅ (phIN) (1) (TBA=tetrabutylammonium cation, phIN=phenyl isonicotinate) cyanido‐bridged chain material. Owing to an appropriate {N6} coordination sphere of Fe(II) centers, 1 reveals a thermal spin crossover (SCO) effect which is complete and cooperative providing a distinct thermal hysteresis loop in magnetic measurements. Moreover, it exhibits simultaneous thermal bistability in (a) visible‐light absorption due to the presence of efficient d‐d electronic transitions in the low‐spin (LS) state, (b) SHG activity as it crystallizes in a polar Cc space group due to the bulky substituent on phIN ligands, and (c) dielectric parameters, including dielectric constant, which can be correlated with subtle changes in polarity between LS and HS (high spin) phases. Thus, we present a remarkable thermally controlled hysteretic behavior in four physical functionalities realized by properly functionalizing an SCO‐active coordination compound.

AbstractHydrogen‐bonded organic frameworks (HOFs) composed of multicomponent molecules in a non‐stoichiometric composition have drawn great interest due to their tunable properties. However, the photobehavior of the single crystals of such mixed HOFs has not been explored. Here, we report on the synthesis, characterization and photobehavior of single crystalline non‐stoichiometric HOFs (NS‐HOFs). NS‐HOFs (BTNT‐1) with various composition ratios were successfully obtained as single crystals from two analogue tetratopic carboxylic acids, possessing naphthalene and benzothiadiazole cores (NTTA and BTTA, respectively). The heterogeneous distribution of the components was thoroughly confirmed by time‐resolved fluorescence microscopy and local crystallographic analysis using focused synchrotron X‐ray radiation. The versatile fluorescence of BTNT‐1 behavior depends on the composition ratio and distribution of the component in the single crystals. We observed not only fluorescence bands with various colors such as purple, blue, green and white, depending on the composition ratios, but also different emission bands from a single crystal. We provide details on their emission lifetimes following the composition, emission color and targeted region on the crystal. This work is the first example of single crystal studies applied to organic porous co‐crystals and demonstrates unique and versatile optical properties of carboxylic acid‐based NS‐HOFs. The results provide a concept of creating functional mixed porous materials capable of different and tunable optical properties.
