Published: October 2023

AbstractPolymerizable deep eutectic solvent (PDES) as a newly emerging type of liquid‐free ionic conductive elastomer is considered to be the most attractive candidate for the next generation of ionotronic devices. However, it remains a huge challenge to integrate high ionic conductivity, excellent mechanical properties, good self‐healing capacity, and robust adhesion into a single material that satisfies the stringent demand of the ionotronic devices in various scenarios. Herein, a liquid‐free ionic elastomer is constructed by incorporating tannic acid‐encapsulated cellulose nanocrystals (TA@CNC) as multifunctional hydrogen bond donors (HBDs) along with poly(acrylic acid) (HBDs) and choline chloride (hydrogen bond acceptors, HBAs) to form a dynamic cross‐linking network through multiple dynamic hydrogen bonds. The presence of the rigid crystalline regions and the sufficient dynamic interaction sites on the TA@CNC endow the resultant elastomers (ACTC) with superior mechanical properties (≈496 kPa, 2400%), robust adhesion (≈68.6 kPa), and good self‐healing property. Benefiting from the above integrated features, the wearable sensors by harnessing the ACTC as a resistance sensing module is constructed that provide unaltered sensing performance under off‐axial deformation (twisting and prick). Additionally, the capacitance pressure sensor with good stability for force distribution is developed, opening up a new avenue for the development of ionotronic devices.

AbstractOxidative stress induced by ischemia‐reperfusion causes severe secondary injury in stroke patients. The blood‐brain barrier (BBB) and the challenges in targeting the stroke core hinder the therapeutic effect of drugs. This study introduces a precise biomimetic drug delivery system called SHp‐NM@Edv/RCD (SNM‐NPs), which possesses multiple stepwise targeting capabilities. SNM‐NPs are encapsulated by the neutrophil membranes (NMs) and exhibit a targeting effect (5.16‐fold) on the inflammatory microenvironment. The modification of stroke‐homing peptides (SHp) makes SNM‐NPs target damaged neurons faster, with a targeting efficiency 5.68 times higher than that of β‐cyclodextrins (RCD). Then, RCD encapsulated in SNM‐NPs responds to reactive oxygen species (ROS), leading to the release of edaravone (Edv), scavenges ROS, inhibits neuroinflammation, and reduces neuronal apoptosis by 90%. Mechanistically, SNM‐NPs deliver Edv precisely to the cerebral ischemia‐reperfusion injury (CIRI) site, resulting in the elimination of ROS, a decrease in the number of microglia, an improvement in tubulin expression in neurons, and the inhibition of neuronal apoptosis through Caspase 3 pathway. Preliminary experiments also show that SNM‐NPs exhibit a good safety profile both in intravenous therapy and in vitro cell experiments. As a result, SNM‐NPs hold promise for further development as effective and safe agents for target therapy of CIRI and other diseases.

AbstractConsidering the high surface defects of polycrystalline perovskite, chemical passivation is effective in reducing defects‐associated carrier losses. However, challenges remain in promoting passivation effects without compromising the carrier‐extraction yield at the perovskite interfaces. In this work, interlayer molecules functionalized with different side groups are rationally designed to investigate the correlation between defect‐passivation strength and interfacial carrier dynamics. It is revealed that Cl‐grafted molecules impose destructive effects on the perovskite structure due to its lower electronegativity and mismatched spatial configuration. The introduction of cyanide (CN) as a side group in molecules also leads to perovskite deformation and unfavorable hole collection. After the molecular optimization, the incorporation of carbonyl (C═O) as the side group (TPA─O) simultaneously promotes the carrier‐collection yield as well as sufficient defect passivation. As a consequence, the devices based on TPA─O yield a champion PCE of 23.25%, along with remarkable stability by remaining above 88.5% of initial performance after 2544 h storage in the air. Furthermore, this interlayer based on TAP─O enables flexible devices to achieve a high efficiency of 21.81% and promising mechanical stability. This work paves the way for further improving the performance of perovskite solar cells.

AbstractAntimony selenosulfide (Sb2(S,Se)3) solar cells bear great potential for sustainable photovoltaic technology, attributed to their excellent semiconductor properties. Despite the encouraging breakthroughs, the efficiency of Sb2(S,Se)3 solar cells still leaves much room for improvement due to the large open‐circuit voltage (VOC) deficit (the radiative VOC limit minus the high VOC). Herein, ammonium sulfide ((NH4)2S) solution is utilized to treat Sb2(S,Se)3 films to tailor their surface properties. The disappearance of the hole defect (H1) and the decrease of the defect concentration of hole defect (H2) confirm that non‐radiative recombination is suppressed greatly. Photovoltage decay lifetime is greatly increases from 67.9 to 297.9 µs. The upshifted valence band maximum optimizes the energy level alignment between the p–n heterojunction, enhancing the carrier transport. Remarkably, this treatment yields a record lowest VOC deficit of 0.49 V by now, and the best device with 10.41% efficiency, ca. 25% improvement over the control device (8.35%). This study provides valuable insight into reducing the VOC deficit in solar cells and related photoelectronic devices by minimizing non‐radiative recombination, and also presents a great potential strategy to achieve the lowest VOC deficit.

AbstractPhototropism and self‐oscillation are both self‐regulating intelligent movements of biological organisms. However, realizing these intelligent movements in one same artificial actuation system remains a great challenge. Here, by introducing dynamic light‐mechanical interaction, a MXene‐based actuator is designed and fabricated that can generate unique self‐adaptive light‐driven actuation from the equilibrium state of phototropic deformation to self‐oscillation. The actuator can autonomously track the incident light, showing a sunflower‐like phototropism. Moreover, by simply installing a load on the actuator to induce self‐shadowing‐enabled negative feedback loop, it can carry the load to continuously oscillate under constant light irradiation, with a frequency of 6.5 Hz, an amplitude of 2.6 mm, and a load‐to‐weight ratio value of 4.7. The oscillation frequency and amplitude can be further adjusted by the incident light power, actuator length, and weight of the installed load. This oscillator can serve as an intelligent light‐powered motor platform. By installing diverse accessories with different functions on the oscillator, it can realize various applications, including information transmission, light‐induced power generation, bionic motions, and multi‐mode intelligent switches. These results provide a simple and versatile strategy for designing a self‐adaptive oscillator driven by light and show the prospect of the oscillator in light‐powered engines and smart machinery systems.

AbstractLow‐dimensional (LD) perovskite has provided an exciting avenue for exploring stable perovskite solar cells (PSCs). However, PSCs based on LD perovskites still suffer from poor efficiency owing to unfavorable charge carrier dynamics. Here, cystamine (CYS) is employed as a ligand to construct LD Dion‐Jacobson (LDDJ) perovskite (CYS)MAn‐1PbnI3n+1 (n = 1, 2, 3…, MA: methylamine) for improving carrier properties. The disulfide bond not only changes the polarization characteristic but also increases the coupling between inorganic slabs due to the low barrier of rotation around the S‐S axis, thus reducing the exciton binding energy of CYS‐based LDDJ perovskite. Disulfide bonds provide a scene for charge localization in the interlayer region, which is conducive to reducing the anisotropy of charge transfer. Thanks to these merits, the (CYS)MA4Pb5I16 film delivers improved carrier diffusion length (electron for 1345 nm and hole for 950 nm) and mobility (9.23 cm2 V−1 S−1). As a result, the (CYS)(MA)4Pb5I16 PSC achieves a champion power conversion efficiency (PCE) of 16.52%, which is much higher than that of HDA and BA cations‐based PSCs (HDA: 1,6‐Hexanediamine, BA: Butylamine). Furthermore, the state‐of‐the‐art device only lost 8% of its initial PCE after 1600 h in the atmosphere.

AbstractThe ever‐growing demand for resources sustainability has promoted the recycle of spent lithium‐ion batteries to a strategic position. Direct recycle outperforms either hydrometallurgical or pyrometallurgical approaches due to the high added value and facile treatment processes. However, the traditional direct recycling technologies are only applicable for Ni‐poor/middle cathodes. Herein, spent Ni‐rich LiNi0.8Co0.1Mn0.1O2 (S‐NCM) to performance‐enhanced single‐crystalline cathode materials is directly recycled using a simple but effective LiOH‐NaCl molten salt. The evolution process of the Li‐supplement and grain‐recrystallization during regeneration is systematically investigated, and the successful recovery of the highly degraded microstructure is comprehensively proven, including significant elimination of Ni2+ and O vacancies. Beneficial from the favorable reconstructed single‐crystalline particles, the regenerated NCM (R‐NCM) represents remarkably enhanced structural stability, electrochemical activity, O2 and cracks suppression during charge/discharge, thus achieving the excellent performances in long‐term cycling and high‐rate tests. As a result, R‐NCM maintains the 86.5% reversible capacity at 1 C after 200 cycles. Instructively, the present molten salt can be successfully applied for recycling spent NCMs with various Li and Ni compositions (e.g., LiNi0.5Co0.2Mn0.3O2).

Published: October 2023

AbstractUnlike absorption‐based colors of dyes and pigments, reflection‐based colors of photonic crystals, so called “structural colors”, are responsive to external stimuli, but can remain unfaded for over ten million years, and therefore regarded as a next‐generation coloring mechanism. However, it is a challenge to rationally design the spectra of structural colors, where one structure gives only one reflection peak defined by Bragg's law, unlike those of absorption‐based colors. Here, we report a reconfigurable photonic crystal that exhibits single‐peak and double‐peak structural colors. This photonic crystal is composed of a colloidal nanosheet in water, which spontaneously adopts a layered structure with single periodicity (407 nm). After a temperature‐gradient treatment, the photonic crystal segregates into two regions with shrunken (385 nm) and expanded (448 nm) periodicities, and thus exhibits double reflection peaks that are blue‐ and red‐shifted from the original one, respectively. Notably, the transition between the single‐peak and double‐peak states is reversible.

AbstractIodine (I2) shows great promising as the active material in aqueous batteries due to its distinctive merits of high abundance in ocean and low cost. However, in conventional aqueous I2‐based batteries, the energy storage mechanism of I−/I2 conversion is only two‐electron redox reaction, limiting their energy density. Herein, six‐electron redox chemistry of I2 electrodes is achieved via the synergistic effect of redox‐ion charge‐carriers and halide ions in electrolytes. The redox‐active Cu2+ ions in electrolytes induce the conversion between Cu2+ ions and I2 to CuI at low potential. Simultaneously, the Cl− ions in electrolytes activate the I2/ICl redox couple at high potential. As a result, in our case, I2‐based battery system with six‐electron redox is developed. Such energy storage mechanism with six‐electron redox leads to high discharge potential and capacity, excellent rate capability, as well as stable cycling behavior of I2 electrodes. Impressively, six‐electron‐redox I2 cathodes can match various aqueous metal (e.g. Zn, Mn and Fe) anodes to construct metal||I2 hybrid batteries. These hybrid batteries not only deliver enhanced capacities, but also exhibit higher operate voltages, which contributes to superior energy densities. Therefore, this work broadens the horizon for the design of high‐energy aqueous I2‐based batteries.

AbstractThe uniformity of rubber products stands as a pivotal indicator for assessing their overall quality. In the case of certain specialized rubber items, such as rubber bladders, uniformity emerges as a decisive criterion that significantly influences their quality evaluation. Numerous factors exert an impact on the homogeneity of rubber products. However, the comprehensive investigation of how the molding process influences such homogeneity remains notably underexplored. To mitigate the potential variability in experimental outcomes, this paper employs distinct pre‐treatment procedures for two types of rubber—designating one for the experimental group and the other for the control group. Subsequently, the items underwent distinct molding procedures to analyze the combined impact of pre‐treatment and molding techniques on the uniformity of rubber products. The findings indicate a notable enhancement in the uniformity of cylindrical rubber products—like rubber bladders—of up to 30% through the implementation of the filtration pre‐treatment process. Additionally, rubber products derived from the injection molding process demonstrated a remarkable 40% increase in uniformity compared to those produced through molding techniques.
Insights to develop tau‐directed therapeutics to protect the synaptic integrity for tauopathies

Published: October 2023

AbstractTauopathy is characterized by the abnormal aggregation of tau proteins. In order to develop drugs for tauopathies, a variety of different therapeutic strategies have been investigated. Synapse loss is a hallmark of tauopathies and is reportedly related to cognitive impairment in Alzheimer's disease as well. Emerging evidence suggests that pathogenic tau species are linked to synaptic dysfunction and synapse loss in tauopathies. As such, a potential therapeutic approach to ameliorate synaptic dysfunction and counteract synaptic loss due to pathogenic tau holds promise. This review highlights the pathological links between tau pathology and synaptic integrity and current efforts to develop therapeutics rescuing synaptic dysfunction for tauopathies, which will help to understand the association between tau and synapses and develop disease‐modifying drugs for tauopathies.

AbstractWe are currently living in a time of several existential threats: the global pandemic COVID‐19, climate change, and the ‘refugee crisis’ caused by violent conflicts and humanitarian catastrophes in Syria, Afghanistan, and Ukraine. These threats do not only affect our well‐being but also our sense of control and security, as well as identities and worldviews having also intergroup consequences. In this study, we investigated the links between perceived existential threats (i.e. COVID‐19, climate change, and refugee crisis in 2015 that multiplied Muslim population in Europe), national and religious identities, and attitudes towards Muslims (i.e. Muslim refugees, Muslim minority, and Muslim converts) among Christian national majority group members in Finland and Italy in 2020. The results were analysed with multigroup structural equation modelling, and they demonstrated some key differences between how threats perceived from climate change and the refugee crisis in 2015 are translated into the reactions towards Muslims. While threats associated with the refugee crisis were detrimental to outgroup attitudes, climate change threats elicited more positive attitudes towards the outgroups studied. Our preliminary analyses suggested that COVID‐19, in turn, seems to elicit feelings of worldview defence through higher levels of national identification with no negative attitudinal ramifications. While Abrahamic identity as a believer was directly associated with more positive attitudes towards Muslims in Italy, it did not account for the link between existential threats and outgroup attitudes. The results are discussed in light of how different threats increase or decrease intergroup harmony.

Confining Ionic Liquids in Developing Quasi‐Solid‐State Electrolytes for Lithium Metal Batteries
Authors: Hu Haiman , Li Jiajia , Ji Xiaoyan 
Published: October 2023

AbstractThe concept of confining ionic liquids (ILs) in developing quasi‐solid‐state electrolytes (QSSEs) has been proposed, where ILs are dispersed in polymer networks/backbones and/or filler/host pores, forming the so‐called confinement, and great research progress and promising research results have been achieved. In this review, the progress and achievement in developing QSSEs using IL‐confinement for lithium metal batteries (LMBs), together with advanced characterizations and simulations, were surveyed, summarized, and analyzed, where the influence of specific parameters, such as IL (type, content, etc.), substrate (type, structure, surface properties, etc.), confinement methods, and so on, was discussed. The confinement concept was further compared with the conventional one in other research areas. It indicates that the IL‐confinement in QSSEs improves the performance of electrolytes, for example, increasing the ionic conductivity, widening the electrochemical window, and enhancing the cycle performance of the assembled cells, and being different from those in other areas, that is, the IL‐confinement concept in the battery area is in a broad extent. Finally, insights into developing QSSEs in LMBs with the confinement strategy were provided to promote the development and application of QSSE LMBs.
Environmental Sustainability of π‐Electron Donor‐Based Deep Eutectic Solvents for Toluene Absorption: A Life‐Cycle Perspective

Published: October 2023

AbstractThe novel π‐electron donor‐based deep eutectic solvents (DESs) have been shown to be a promising type of absorbent with excellent performance on toluene absorption. However, their greenness or sustainability is still unclear. Thus, to bridge the gap and give a comprehensive evaluation for their industrialization potential, the life cycle assessment (LCA) was used to evaluate the potential environmental impacts incurred from their production and usage for absorbing toluene. The environmental profiles are also compared with that of popular choline chloride (ChCl) based DES, common organic solvent triethylene glycol (TEG) and ionic liquid ([EMIM][Tf2N]). The results indicate that among the involved hydrogen bond acceptors (HBAs), TEBAC generally imparts lower environmental impacts than other HBAs but has higher impacts than ChCl. Although TEBAC‐PhOH is not the most environmentally friendly absorbent during the production stage, its outstanding absorption performance minimizes the environmental impact when absorbing the same mass of toluene. Furthermore, the environmental impacts of the toluene absorption process using TEBAC‐PhOH is significantly lower than that of [EMIM][Tf2N], slightly lower than TEG. Therefore, considering both absorption performance and environmental impacts, TEBAC‐PhOH can be used as a promising “green and sustainable” toluene absorbent to traditional absorbents and ionic liquids.
