It is popular to choose the cubic phase Li7La3Zr2O12(c-LLZO) to synthesize the PEO-based complex membrane in all-solid-state battery. In this work, Ba/Nb elements were selected to achieve Li6.75La3Zr1.75Nb0.25O12 (LLZNO) and Li7La2.75Ba0.25Zr1.75Nb0.25O12 (LLBZNO) with high ion conductivity, which effectively enhance the electrochemical properties of the complex solid membrane and the all-solid-state battery. The higher ion mobility of LLBZNO compared to that of LLZNO and LLZO is calculated by ab-initio molecular dynamics (AIMD) simulation and further confirmed by experiments. Results show that the cubic phase of LLBZNO is more stable than that of LLZNO. The complex membrane of LLBZNO@ polyethylene oxide (PEO) (CPE-2-x wt%) exhibits the better electrochemical properties than LLZNO@PEO (CPE-1-x wt%) complex membrane. In detail, the CPE-2–10 wt% has the outstanding lithium transfer number ({t}_{{{Li}}^{+}}) of 0.63, as well as the excellent compatibility with lithium metal anode. In addition, at 0.1 mAcm−2, the lithium/CPE-2–10 wt%/lithium symmetric cell remains stable after 1000 h. It is LLBZNO that makes LLBZNO@PEO composite polymer electrolyte(CPE) the potential for the application in all-solid-state lithium battery.

Supported ionic liquid membranes (SILMs), owing to their capacities in harnessing physicochemical properties of ionic liquid for exceptional CO 2 solubility, have emerged as a promising platform for CO 2 extraction. Despite great achievements, existing SILMs suffer from poor structural and performance stability under high-pressure or long-term operations, significantly limiting their applications. Herein, a one-step and in situ interfacial polymerization strategy is proposed to elaborate a thin, mechanically-robust, and highly-permeable polyamide armor on the SILMs to effectively protect ionic liquid within porous supports, allowing for intensifying the overall stability of SILMs without compromising CO 2 separation performance. The armored SILMs have a profound increase of breakthrough pressure by 105% compared to conventional counterparts without armor, and display high and stable operating pressure exceeding that of most SILMs previously reported. It is further demonstrated that the armored SILMs exhibit ultrahigh ideal CO 2 /N 2 selectivity of about 200 and excellent CO 2 permeation of 78 barrers upon over 150 h operation, as opposed to the full failure of CO 2 separation performance within 36 h using conventional SILMs. The design concept of armor provides a flexible and additional dimension in developing high-performance and durable SILMs, pushing the practical application of ionic liquids in separation processes.

Amphibious proton exchange membranes (PEMs) which could be used under both wet and dry conditions were prepared by sol–gel method in this work. Those novel hybrid PEMs were constructed by three parts: (1) polysiloxane with two basic sites (–NH– on the pendant and N– in the triazole); (2) H 3 PO 4 as the proton source; (3) poly(vinyl alcohol) (PVA) which had good film-forming capacity and ability to anchor the H 3 PO 4 under wet conditions. The resulting hybrid membranes were thermally stabilized up to 200 °C. A matrix-change between polysiloxane and PVA could be observed at a high PVA doping level. The proton conducting property of these membranes was investigated under both hydrous and anhydrous conditions. From 25 to 120 °C, the non-soaked and soaked (soaked in the water) membranes showed the proton conductivity of 19–68 and 9–31 mS cm −1 at 100% relative humidity (RH), respectively. Under completely dry conditions, the proton conductivity of these membranes showed large dependence on the temperature and the proton conductivity of 4.7–21 mS cm −1 was achieved at 150 °C for these membranes. The excellent performance of these hybrid membranes under both wet and dry conditions demonstrated that they have potential use as electrolytes in polymer electrolyte membrane fuel cells (PEMFCs) operating either in a watery or in a water-free environment and so called “amphibious” proton conducting membranes.

Migrating cells form retraction fibers (RFs) at their trailing edge, where migrasomes, ranging from 0.5 to 3 μm, grow at the tips or intersections of RF. Migrasomes play crucial roles when released extracellularly, but before release, they remain physically connected to cell body via RFs, facilitating long-range signal transmission. Since many signaling molecules are highly localized, the mechanism of long-range signal transmission has not been fully understood. Here, we demonstrated that tubular ER extended into RFs and localized to migrasomes, which depended on microtubule-regulated ER extension. Tubular ER adhered to migrasome biogenesis site through ER-plasma membrane contact sites (ER–PM MCSs). Notably, tubular ER functions as cholesterol and calcium reservoir, facilitating the transfer of cholesterol and calcium to migrasomes, potentially at ER–PM MCSs that promoted membrane expansion, stability, and localized secretion of migrasome. Our findings revealed a novel dynamic of tubular ER and provided a new mechanism for long-range site-specific calcium and cholesterol transmission through RFs and migrasomes in migrating cells.

A novel omniphobic-hydrophilic Janus membrane was developed to tackle the problems of traditional hydrophobic membrane wetting and fouling during membrane distillation (MD). The asymmetric membrane was first fabricated by simply depositing dopamine (DA) on a commercial polytetrafluoroethylene/polyethylene terephthalate (PTFE/PET) membrane. The low-surface-energy omniphobic surface with multilevel re-entrant structures was developed via spraying cylindrical palygorskite (PAL) nanorods , which were modified by polydopamine (PDA) coatings and fluorinated by 1 H , 1 H , 2 H , 2 H -perfluorodecyltriethoxysilane (17FAS). The asymmetric Janus membrane possessed outstanding wettability : the top layer achieved omniphobic (163.9°) while the bottom layer displayed underwater superoleophobicity (157.2°). In direct contact membrane distillation (DCMD) operations, the Janus membrane exhibited a robust desalination performance (salt rejection of ~100%) and excellent stability (over 50 h) while treating different types of surfactant-stabilized mineral oil-in-water emulsions, demonstrating the superior wetting and fouling resistance of the membrane. Overall, the results exemplified an effective strategy for engineering Janus membranes with an omniphobic PAL and a hydrophilic PDA layer. Importantly, the Janus membrane shows broad application prospects in the field of MD processes for water recovery from industrial wastewater containing complex compounds.

With the development of new sensor technology, flexible piezoelectric materials possessing exceptional mechanical-to-electrical energy conversion capabilities hold great promise for application in a variety of sectors, including biomedicine, flexible robotics, and wearable electronic devices. This work reports the successful growth of an all-inorganic transparent Bi(Fe 0.95 Mn 0.05 )O 3 (BFOMn) film on the Mica substrate using a straightforward one-step sol–gel method. The prepared BFOMn thin film enables the optimum electrical properties with a saturated polarization of ~ 92 μC/cm 2 , a remanent polarization of ~ 74 μC/cm 2 , and a high piezoelectric constant d 33 of ~ 405 pm/V. Concurrently, the film exhibits exceptional adaptability without compromising its electrical performance, as evidenced by its capacity to undergo a tight curve with a radius of just 2 mm. Utilizing this BFOMn film, the fabricated flexible piezoelectric energy harvester (FPEH) has exceptional energy collecting capabilities, producing an output voltage of 15 V, a short current of 130 nA, and a notable force sensitivity of 4 V·N −1 before poling. It can also be employed to monitor human actions, such as hand hammering, hand clapping, and foot stepping. This work demonstrates the potential of the BiFeO 3 -based FPEH/sensor in the field of new intelligent electronics.

The graded-refractive-index SiO 2 antireflective (AR) films were prepared using the sol–gel method. A monolayer with a porous nanonetwork structure was designed as the mixed volume ratio of 70:30 between the alkali- and acid-catalyzed SiO 2 sols. As the top layer, the hexamethylisilazane (HMDS) modified alkali catalyzed SiO 2 sols induced SiO 2 nanoparticles transforming from hydrophilic to hydrophobic nature. In comparison with the structures of monolayer and bilayer films, the AR properties and laser damage resistance were investigated in detail. By designing the nanostructures of the bottom and top layers, the graded- refractive-index SiO 2 film was obtained, consequently enhancing the AR performance. In the bilayer film, the transmittance reached ∼ 98%@532 nm and 97%@1064 nm, respectively, corresponding to the obvious reduction of reflectivity. The assembly of the bilayer SiO 2 film increased the laser-induced damage threshold by ∼ 30% from 25.3 J/cm 2 (monolayer) to 33.1 J/cm 2 (bilayer). The inducement of laser damage was further revealed by the analysis of morphological changes induced by laser damage, attributing to the initiator absorption of environmental contaminations. Therefore, the SiO 2 film not only provided a graded-refractive-index structure with good AR performance, but also had high laser damage resistance. The unique graded-refractive-index structure of SiO 2 AR films offers a new strategy for improving the performance of optical components in high-power laser systems.

Poly(m-phenylene isophthalamide) (PMIA) membranes are promising heat-tolerant separator candidates of lithium-ion batteries (LIBs), while their wettability toward carbonate electrolyte and corresponding batteries performance are not desirable. Herein, PMIA membranes coated with ultrathin mussel-inspired polydopamine (PDA) layer were fabricated as separators in LIBs. The introduced amino, quinonyl, and catechol groups in PDA coating could enhance the wettability of the resultant PMIA-PDA separator toward electrolyte. The PMIA-PDA separator had excellent thermal stability, showing a thermal shrinkage of 5.2% at 200 °C. The contact angle of the thermal-treated PMIA-PDA separator could maintain at 26.1°, which decreased by 42.7% compared with the pristine PMIA separator. The PMIA-PDA separator also displayed a high ionic conductivity (0.86 mS cm −1 ) and a low interfacial electric resistance (62.4 Ω). Consequently, the assembled LiCoO 2 /PMIA-PDA/Li battery achieved good cyclic stability with the capacity retention of 84.3% (121.1 mAh g −1 ) after 100 cycles under 30 °C. More significantly, the relevant capacity retention remained at 89.0% (127.5 mAh g −1 ) under 60 °C, which implied a great potential of PMIA-PDA membranes as separators of high-safety LIBs.

In order to solve the increasingly serious problem of printing and dyeing wastewater pollution, a kind of novel, efficient, and reusable spunlaced viscose/polyaniline-ZnO/GO fibrous membrane was fabricated in this work. Specifically, spunlaced viscose/polyaniline conductive fibrous membrane was firstly prepared by in-situ growth method, followed with the growth of zinc oxide (ZnO) and graphene oxide (GO) via the hydrothermal route to obtain spunlaced viscose/PANI-ZnO/GO fibrous membrane (SV@PANI-ZnO/GO membrane). The results show that the decolorization rate of SV@PANI-ZnO/GO membrane for methylene blue (5.0 mg/L) was 97.4% within 120 min, and the decolorization rate remained above 76.7% after five cycles. Moreover, the reaction process conformed to a quasi-first order kinetic model with the apparent rate constant of 0.0209 min–1. Meanwhile, the free radical capture experiment revealed that the main reactive species in the decolorization process was .OH. This work may provide a new method for designing photocatalytic materials for environmental applications.

Human respiration reflects abundant physiological information and could enable non-invasive monitoring, providing information about various biological parameters such as respiration rate and depth. The rapidly growing field of humidity sensors bring forward the requirement for good performance. In this work, by virtue of good hydrophilicity and conductivity, a MXene/thermoplastic polyurethane (TPU) composite film is prepared by coating MXene nanosheets on chitosan-modified TPU electrospun nanofibers via electrostatic interactions, for fabricating a humidity sensor. Based on the principle that the tunnel resistance changing with water molecules influences the distance of MXene nanosheets, the MXene/TPU humidity sensor exhibits fast response (12 s), wide humidity response range (11–94% RH), low hysteresis (<7% RH), and excellent repeatability. The humidity sensor can be assembled with a face mask for distinguishing different human respiration patterns and accurately monitoring respiratory signals during different physical activities, suggesting its promising applications in the fields of respiratory monitoring.

Summary Owing to its unparalleled theoretical energy density, the Li-O 2 batteries are thought to be one of the most promising energy storage systems, but its application is seriously hindered by its potential safety risks arising from the passivation and corrosion of lithium anode. To address these issues, it is an efficient way to develop functionalized separator that could prevent the migration of anions and macromolecules from cathode toward anode. Herein, a novel Nafion-functionalized polyethersulfone (PES)-based ion-permselective separator was prepared by using non-solvent induced phase separation (NIPS) method. The Nafion ensures a better physical strength of the composite separator, and further characterizations show that the obtained composite separator owns good ionic conductivity (0.52 mS cm −1 ), high lithium ion migration number (0.80), and better cyclic stability (120 cycles, 1000 mAh g −1 ). Consequently, the composite separator serves as an excellent candidate to solve the “shuttle effect” of redox mediators (RMs), the assembled Li-O 2 battery with composite separator adding LiI as RMs presents lower charge overpotential and longer cycle stability (170 cycles, 1000 mAh g −1 ).

The anticorrosion effect of thiazolyl blue (MTT) for copper in 3% NaCl at 298 K was researched by electrochemical methods, scanning electron-microscopy (SEM), and atomic force microscopy (AFM). The results reveal that MTT can protect copper efficiently, with a maximum efficiency of 95.7%. The corrosion inhibition mechanism was investigated by X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectral (FT-IR), and theoretical calculation. The results suggest that the MTT molecules are adsorbed on metal surface forming a hydrophobic protective film to prevent copper corrosion. It also indicates that the MTT and copper form covalent bonds. The molecular dynamic simulation further gives the evidence for adsorption. The adsorption isotherm studies demonstrate that a spontaneous, mixed physical and chemical adsorption occurs, which obeys Langmuir adsorption isotherm. The present research can help us better understand the corrosion inhibition process and improve it.
