AbstractMagnetotactic bacteria are microaerobic microorganisms that take up iron from solution and crystallize magnetite nanoparticles called magnetosomes, enclosed by membrane intracellularly and mainly formed by the magnetosome membrane‐specific 6 (Mms6) gene. M2 macrophages are transfected by magnetotactic bacteria‐derived Mms6 gene to form magnetic bio‐nanoparticles. Under myelin debris‐rich hypoxic stress in the spinal cord injury (SCI) microenvironment, Mms6‐transfected M2 macrophages can antagonize ferroptosis. Meanwhile, transplantation of Mms6‐transfected M2 macrophages into SCI mice through intracerebroventricular or intravenous injection can effectively promote structural repair and locomotor functional recovery. As a proof of concept, this study provides a novel strategy in immune cell therapy, which supports the survival and strengthens the function of M2 macrophages based on magnetic bio‐nanoparticles which help M2 macrophages to resist ferroptosis. This study also sheds light on this cross‐species applications for treating traumatic injury and inflammatory diseases.

AbstractAll‐solid‐state batteries (SSBs) represent one of the most promising avenues for surpassing the energy density limitations of conventional lithium‐ion batteries. However, the unstable interfacial contact between the solid‐state electrolyte and the electrode poses a critical challenge for practical applications. To tackle this issue, a hybrid system incorporating both liquid electrolytes (LEs) and sulfide solid‐state electrolytes may serve as a viable alternative. In this hybrid system, the LE facilitates the in situ formation of a solid electrolyte interphase layer, thereby enhancing the physical interface contact. Consequently, the electrochemical lifetime of the hybrid all‐SSBs is significantly improved, as evidenced by the stable lithium plating behavior observed through analytical techniques such as in situ X‐ray imaging. Nonetheless, the hybrid system exhibits clear limitations, and several issues that need to be addressed for its practical implementation are identified. In conclusion, potential solutions that could be employed to overcome these challenges are proposed.

AbstractThe surface treatment for solution‐processed perovskite films using molecular passivation agents has been reported to be critical for improving the performance of perovskite light‐emitting diodes (PeLEDs). Generally, most studies emphasized the binding effect between passivation molecules and perovskite surface, while halide perovskites are dominated by multiple defects and need more comprehensive passivation, which is often neglected. Here, a molecule of 5‐ammonium valeric acid trifluoroacetate (5‐AVATFA) with multi‐functional groups is rationally developed to modify the interface of advanced PeLEDs. Combining experimental and density functional theory analysis, the synergism effects of reduced surface defects and increased steric hindrance of 5‐AVATFA, which can greatly suppress the ion migration of PeLEDs, are demonstarated. Because of the passivation effect of multi‐functional 5‐AVATFA, an optimal device with an external quantum efficiency of 22.32%, a radiance of 558.46 W sr−1 m−2, and an extended half‐lifetime of 103.3 h is obtained.

AbstractImage stabilization is a crucial field in machine vision, aiming to eliminate image blurring or distortion caused by the camera or object jitter. However, traditional image stabilization techniques often suffer from the drawbacks of requiring complex equipment or extensive computing resources, resulting in inefficiencies. In contrast, the human retina performs a highly efficient all‐in‐one system, encompassing the detection and processing of light stimuli. In this study, an all‐optically controlled retinomorphic memristor based on the CsxFAyMA1‐x‐yPb(IzBr1‐z)3 is proposed, which integrates perception, storage, and processing functions. This memristor exhibits significant advantages in image stabilization. It is capable of positively and negatively modulating its conductance using specific intensities (11.8 and 0.9 mW cm−2, respectively) of red light (630 nm). To demonstrate the effectiveness of the proposed approach, handwritten digit recognition simulations are conducted. The application of specific light stimuli effectively highlights the characteristics of blurred images. The processed images are then fed into a conductance‐mapped neural network for rapid recognition. Remarkably, the recognition rates of the processed images reach 83.5% after 19 000 iterations, surpassing the performance of blurred images (only 56.2% after 19 000 iterations). These results highlight the immense potential of retinomorphic memristors as the hardware foundation for next‐generation image stabilization systems.

AbstractMetal halide perovskite materials have emerged as a promising class of semiconductors for high‐performance optoelectronic applications, particularly for light‐emitting diodes (LEDs), due to their high quantum efficiency, facile color tunability, narrow emission line widths, as well as cost‐effectiveness. Despite the great successes on green and red perovskite LEDs (PeLEDs), the external quantum efficiency (EQE) of blue PeLEDs still lags far behind that of green and red counterparts. Here, wavelength tunable pure and deep blue PeLEDs with high EQE are presented, achieving 17.5% and 10.8% for emission wavelengths of 472 and 461 nm, respectively. The wavelength tenability and high EQE are attributed to the unique vertically graded bandgaps and grain boundary organic shells in the perovskite films. The results demonstrate a significant performance improvement in blue PeLEDs, provide a novel route to fabricate high‐performance pure and deep blue PeLEDs that can match the performance of the green and red PeLEDs for future lighting and display applications.

Published: September 2023

AbstractImpaired antigen presentation either in dendritic cells (DCs) or tumor cells impedes the triggering of antitumor immunity or tumor cell killing, resulting in failures of multiple types of cancer immunotherapy. Herein, the strategy of using dual‐targeting nanomedicines to simultaneously improve the presentation of tumor antigens by both DCs and tumor cells is proposed. It is shown that tuning of surface charge of nanoparticles (NPs) by incorporating different amounts of cationic lipids alters the in vivo NP tissue accumulation and cellular targeting profiles. NPs with moderately positive surface charge (≈20 mV) achieve efficient accumulation in tumors and lymph nodes and dual‐targeting to both DCs and tumor cells. As a proof‐of‐concept demonstration, siRNA against YTH N6−methyladenosine RNA binding protein 1 (YTHDF1) is delivered by the dual‐targeting NPs to inhibit excessive antigen degradation in both DCs and tumor cells. For DCs, YTHDF1 downregulation promotes tumor antigen cross‐presentation and cross‐priming of antigen‐specific T cells. For tumor cells, it enhances the presentation of endogenous tumor antigens and hence improves both the recognition and killing of tumor cells by primed antigen‐specific T cells. The dual‐targeting nanomedicines generate efficient antitumor immunity.

AbstractThe low cost and intrinsic safety of rechargeable aqueous zinc‐ion batteries (ZIBs) contribute to their significant potential in grid‐level energy storage systems. However, the limited cathode options still hinder the development of ZIBs, which always delivers poor rate capacities and cycling stability. Herein, Monoclinic phase H3.78V6O13 microspheres with a stable internal framework and intrinsic metallic properties as a high‐performance cathode for ZIBs are proposed and utilized. The reversible Zn2+insertion/de‐insertion mechanism in H3.78V6O13through ex situ X‐ray diffraction, X‐ray absorption near‐edge structure, and in situ Raman involves the enlargement/shrink of interplanar distance, the decrease/increase of the V valance, and the open/recombine of V─O/V─V bonds. Further, experiments and theoretical calculations elucidate the superior electrochemical performance and extraordinary reaction kinetics in H3.78V6O13. The as‐prepared H3.78V6O13 cathode delivers high specific capacity of 406 mAh g–1 at 0.1 A g–1, excellent structure stability with 100% manifested after 120 cycles at 0.5 A g–1, 72.9% retained after 15 000 cycles at 10 A g–1. This research offers distinctive perspectives on the development of high‐performance cathode materials for ZIBs and enhances the understanding of the electrochemical reaction mechanisms of vanadium oxides.

AbstractRecently, lots of researches have focused on enhancing the structure stability of LiCoO2 (LCO) at a cutoff voltage of 4.6 V (vs Li/Li+) at room temperature. However, the high temperature (≥45 °C) performances are more significant for practical applications. Herein, the mechanism of unsatisfactory structure stability of LCO at 45 °C via comparing a commercial LCO (C‐LCO) and a surface optimized LCO (O‐LCO) is revealed first. The deteriorated structure stability of LCO at 45 °C is mainly due to two aspects: i) the promoted bulk Li+ ion diffusion kinetics at 45 °C leads to a higher state of charge for the charged LCO, which triggers more side reactions; ii) the more prominent surface structure collapse at 45 °C blocks the Li+ ion transport channels. Surface optimizations, including the anions (F− and PO43−) and cations (Al3+) surface modulation and a subsurface spinel reinforcement, are comprehensively applied to alleviate the side reaction and structure collapse issues of O‐LCO, leading to a high reversible discharge capacity of 238 mAh g−1, as well as an obviously enhanced cycle and floating stability at 45 °C and beyond 4.6 V. A new insight is provided here for developing more advanced and practical high‐voltage LCO.

AbstractThe practicality of aqueous zinc ion batteries (AZIBs) for large‐scale energy storage is hindered by challenges associated with zinc anodes. In this study, a low‐cost and multi‐function electrolyte additive, cetyltrimethyl ammonium bromide (CTAB), is presented to address these issues. CTAB adsorbs onto the zinc anode surface, regulating Zn2+ deposition orientation and inhibiting dendrite formation. It also modifies the solvation structure of Zn2+ to reduce water reactivity and minimize side reactions. Additionally, CTAB optimizes key physicochemical parameters of the electrolyte, enhancing the stability of the electrode/electrolyte interface and promoting reversibility in AZIBs. Theoretical simulations combined with operando synchrotron radiation‐based in situ Fourier transform infrared spectra and in situ electrochemical impedance spectra further confirm the modified Zn2+ coordination environment and the adsorption effect of CTAB cations at the anode/electrolyte interface. As a result, the assembled Zn‐MnO2 battery demonstrates a remarkable specific capacity of 126.56 mAh g−1 at a high current density of 4 A g−1 after 1000 cycles. This work highlights the potential of CTAB as a promising solution for improving the performance and practicality of AZIBs for large‐scale energy storage applications.

AbstractThis study presents photonic vertical cavities consisting of nonlinear materials embedded in photonic crystals (PhCs) for resonantly enhancing second harmonic generation (SHG). Previous attempts at SHG in such structures have been limited to efficiencies of 10−7 to 10−5, but a high SHG efficiency of 0.28% by constructing a vertical cavity with a lithium niobate membrane placed between two PhCs is demonstrated, which exhibits high‐quality resonances. The results open up new possibilities for compact laser frequency converters that can have a revolutionary impact on the fields of nonlinear optics and photonics.

AbstractSelf‐assembly, the spontaneous ordering of components into patterns, is widespread in nature and fundamental to generating function across length scales. Morphogen gradients in biological development are paradigmatic as both products and effectors of self‐assembly and various attempts have been made to reproduce such gradients in biomaterial design. To date, approaches have typically utilized top‐down fabrication techniques that, while allowing high‐resolution control, are limited by scale and require chemical cross‐linking steps to stabilize morphogen patterns in time. Here, a bottom‐up approach to protein patterning is developed based on a novel binary reaction‐diffusion process where proteins function as diffusive reactants to assemble a nanoclay‐protein composite hydrogel. Using this approach, it is possible to generate scalable and highly stable 3D patterns of target proteins down to sub‐cellular resolution through only physical interactions between clay nanoparticles and the proteins and ions present in blood. Patterned nanoclay gels are able to guide cell behavior to precisely template bone tissue formation in vivo. These results demonstrate the feasibility of stabilizing 3D gradients of biological signals through self‐assembly processes and open up new possibilities for morphogen‐based therapeutic strategies and models of biological development and repair.

AbstractMixed halide perovskite nanocrystals in the form of cesium/formamidinium lead triiodide ((Cs:FA)PbI3) offer great potential for efficient and stable solar cells. To date, large‐scale production with roll‐to‐roll compatible deposition methods remains difficult and requires detailed research on each involved processing step. Here, a proof‐of‐concept study about slot‐die coating (printing) the active layer of (Cs:FA)PbI3‐based nanocrystal solar cells is presented. Structural and morphological changes during ligand exchange of long‐chain oleic acid and oleylamine by Pb(NO3)2, and top‐layer FAI passivation are investigated. Ligand exchange improves the processability of the nanocrystal layer and enhances charge transport. It also changes texture from face‐on toward edge‐on orientation as grazing‐incidence X‐ray scattering studies indicate. Ligand exchange and FAI passivation redshift photoluminescence and prolong charge carrier lifetime in the printed nanocrystal films. The proof‐of‐concept feasibility of printing metal halide perovskite nanocrystal films for solar cells is shown by building 20 devices with a median power conversion efficiency of 6.39%.

Published: September 2023

AbstractElectromagnetic wave multiplexing within a compact ultrathin device is pivotal for high‐capacity communications, wireless power transfer, and other applications. Among them, the independent amplitude and phase (AP) control is necessary, and the decoupling of full‐space scattering channels such as reflection (R) and transmission (T) is favoured for high capacities of information processing. This is yet extremely challenging, even at a single frequency, because A and P are essentially correlated and the R‐T channels are usually coupled. Here, a triband multichannel metasurface is proposed and demonstrated, with a frequency‐direction multiplexed paradigm for on‐demand control of both AP across three independent R‐T channels. For practical realization with high efficiency, a judiciously engineered four‐layer compound meta‐atom is proposed. Such a sophisticated multiplexing can facilitate powerful capability in wavefront control and significantly enrich the capacity as well as degrees of freedom for design. For verification, a proof‐of‐concept metadevice has been devised and experimentally demonstrated at microwave frequency, showcasing transmissive and reflective dual‐vortex beams along x and y directions at 7 and 10.2 GHz, respectively, while transmissive dual focusing at 15.7 GHz. This strategy opens a new avenue for circularly‐polarized AP control toward the capacity limit of frequency and direction and for novel functional metadevices with high integration.

AbstractThe emerging Internet of Things (IoTs) invokes increasing security demands that require robust encryption or anti‐counterfeiting technologies. Albeit being acknowledged as efficacious solutions in processing elaborate graphical information via multiple degrees of freedom, optical data encryption and anti‐counterfeiting techniques are typically inept in delivering satisfactory performance without compromising the desired ease‐of‐processibility or compatibility, thus leading to the exploration of novel materials and devices that are competent. Here, a robust optical data encryption technique is demonstrated utilizing polymer‐stabilized‐liquid‐crystals (PSLCs) combined with projection photoalignment and photopatterning methods. The PSLCs possess implicit optical patterns encoded via photoalignment, as well as explicit geometries produced via photopatterning. Furthermore, the PSLCs demonstrate improved robustness against harsh chemical environments and thermal stability and can be directly deployed onto various rigid and flexible substrates. Based on this, it is demonstrated that a single PSLC is apt to carry intricate information or serve as an exclusive watermark with both implicit features and explicit geometries. Moreover, a novel, generalized design strategy is developed, for the first time, to encode intricate and exclusive information with enhanced security by spatially programming the photoalignment patterns of a pair of cascade PSLCs, which further illustrates the promising capabilities of PSLCs in optical data encryption and anti‐counterfeiting.

AbstractExperience and credence characteristics are hard to assess when consumers select food products. Therefore, consumers who are unfamiliar with specific products typically use search characteristics as a proxy for product quality. As search characteristics are pivotal in consumers' decisions, we expect them to be reflected in the resulting product prices in the beer market. Besides traditional search characteristics such as beer color or fermentation type, new search characteristics such as online consumer ratings are emerging in beer markets all over the world. Thus, we use a hedonic price estimation to learn about the relative importance of traditional versus new search characteristics in the Belgian beer market. Specifically, the beer prices for 1517 different beer products of two large beer retailers are investigated to compare the role of traditional beer characteristics—color, fermentation type, beer style, origin, brewery type, and alcohol percentage—with the role of online beer ratings from the platform RateBeer.com. We find that while traditional characteristics still play a key role in the beer market, the role of online ratings seems dependent on the retail context [EconLit Citations: C36 Instrumental Variables Estimation, D83 Search—Communication, Q11 Agriculture—Prices, Q18 Food Policy].

AbstractINTRODUCTIONImpaired cognition and instrumental activities of daily living (iADL) are key diagnostic features of dementia; however, few studies have compared trajectories of cognition and iADL.METHODSParticipants from the IDEAL study comprised 1537, 1183, and 851 people with dementia, and 1277, 977, and 749 caregivers at baseline, 12 and 24 months, respectively. Addenbrooke's Cognitive Examination‐III and Functional Activities Questionnaire were used to measure cognition and iADL, respectively. Scores were converted to deciles.RESULTSSelf‐rated iADL declined on average by ‐0.08 (‐0.25, 0.08) decile points per timepoint more than cognition. Informant‐rated iADL declined on average by ‐0.31 (‐0.43, ‐0.18) decile points per timepoint more than cognition.DISCUSSIONCognition and self‐rated iADL declined at a similar rate. Informant‐rated iADL declined at a significantly greater rate than cognition. Therefore, either cognition and perceived iADL decline at different rates or informants overestimate increasing iADL difficulties compared to both cognition and self‐ratings.Highlights
Self‐ratings of the degree of functional difficulties were consistent with cognition
Decline in self‐rated everyday activities was consistent with cognitive decline
Informant‐ratings of everyday activities declined more than cognition
