Abstract :
Green hydrogen is currently the dominant trend in the evolution of hydrogen energy, producing almost no greenhouse gas emissions. Alkaline water electrolysis (AWE) is recognized as a leading and well-established technology for producing green hydrogen. However, safety hazards may occur during hydrogen production currently as defective commercial separate membranes used in the AWE process. Therefore, it is imperative to create a membrane characterized by low area resistance, high stability, and high bubble point pressure (BPP) to realize high-performance AWE. Herein, we synthesize alumina-based composite membranes with Y2O3-added and polyethylene glycol coupling agent functionalized Al2O3 for AWE through a phase inversion method. The porous composite membrane exhibits excellent hydrophilicity, with a lower contact angle of approximately 55 degrees. It also presents exceptional performance metrics, including a low area resistance of about 0.17 Omega cm(2), an ultrahigh BBP of approximately 4.4 bar, and excellent mechanical properties with a tensile strength of around 25 MPa. The membranes achieved a current density of up to 2.5 A cm(-2) under 2.0 V voltage in a 30 wt% KOH solution at 80 degrees C by utilizing commercial catalysts. Notably, the composite membranes exhibited remarkable stability, maintaining operation for over 1200 h at a 2.0 A cm(-2) current density without any performance degradation at 80 degrees C. Furthermore, this composite membrane possesses outstanding gas-barrier capability with H-2 and O-2 purity higher than 98.70 % and 99.69 %, respectively. The above results demonstrate that the prepared novel high-performance alumina-based composite membrane for hydrogen generation has significant potential for applications within the AWE process.

Abstract :
Highly permeable polyamide (PA) membranes with precise ion selection can be used for many energy-efficient chemical separations but are limited by membrane inefficiencies. Herein, polyphenol-mediated ZIF-8 nano- particles with hydroxyl-rich hollow structure were synthesized by tannic acid tailored regulation. PA-based membranes with fast penetration, high retention, and precise Cl-/SO42- selection were then synthesized through spatially and temporally controlling interfacial polymerization with modified ZIF-8 nanoparticles (tZIF8) as aqueous phase additives or as interlayers. The effects of the embedding position of tZIF-8 on the structure, morphology, physicochemical properties, and performance of PA-based membranes were explored through a sequence of characterization techniques. The results revealed that the PA-based membrane with tZIF-8 embedded in the PA layer could achieve a high water permeance of 24.8 L m- 2 h- 1 bar- 1 with a high retention of 99.4 % Na2SO4 and a Cl-/SO42- selectivity of 141, which was superior to most state-of-the-art PA-based membranes. Comparatively, the Cl-/SO42- selection of the PA-based membrane with tZIF-8 embedded between the PA layer and the substrate was 136, while the water permeance was slightly enhanced to 28.2 L m- 2 h- 1 bar- 1 . Excitingly, the resulting membranes all exhibit superior antifouling properties and stability. Our facile strategy for tuning membrane microstructures provides new ideals into the development of highly permeable and excellently selective PA-based membranes for precise ion sieving.

Abstract :
The development of harnessing energy from surrounding humidity has been impeded by obstacles such as ambiguous ion migration mechanism and the restricted electrical output of devices designed to generate power from moisture. Herein, a novel hygroscopic network is presented that enhances ion migration by employing a random copolymerization of acrylamide (AAm) and 2-acrylamide-2-methylpropanesulfonic acid (AMPS). This method strategically positions sulfonic acid groups within hydrogels, which can release protons, in the presence of LiCl. Both experimental data and molecular dynamic simulations indicate that ion migration primarily occurs through a proton hopping mechanism, protons are released from the & horbar;SO3H and interact with adjacent confined water molecules, creating a network that facilitates swift proton migration along hydrogen-bonded chains. The developed single sulfonic acid side chain@hydrogel-based moisture-electric generator (SHMEG) exhibits a sustained open-circuit voltage (Voc) of 0.89 V and a current density of 173 mu A cm-2 for over 1400 h. Additionally, the SHMEG's scalability allows it to be connected in series or parallel, which provides adaptability and lightness. These features render the SHMEG suitable for powering a variety of commercial devices, such as mobile phone, health monitoring sensors and nighttime illumination, making it a promising, high power, and environmentally friendly energy solution.

Abstract :
Supercritical carbon dioxide (sCO2) corrosion remains a significant and ongoing impediment within the domain of carbon capture, utilization, and storage (CCUS) technologies, necessitating the advancement of robust mitigation tactics. Based on experimental and theoretical investigations, we have studied the inhibition performance of a composite formulation on X80 steel. The in-situ electrochemical studies have confirmed the superior performance of this composite inhibitor, achieving an inhibition efficiency exceeding 99.79%. Through atomistic simulations, we gain mechanistic insights at the molecular level, revealing how the dissociated heteroaromatic species of the composite inhibitor effectively chelate to the metal surface through unsaturated oxygen-carbon pairings, thereby enhancing surface coverage. Such findings provide a prototypical structure- activity relationship to inform the application of optimized corrosion inhibitor formulations in the challenging setting of sCO2 environments.

Abstract :
Wearable electronic textiles, capable of detecting human motions and recognizing gestures, represent the forefront of personalized electronics. However, the integration of high stretchability, sensitivity, durability, and self-healable/self-bondable capabilities into one platform remains challenging. Herein, mussel-inspired stretchable, sensitive, and self-healable/self-bonded conductive yarns enabled by dual electron transfer pathways and dual encapsulation technology are presented. Specifically, covered spandex yarns provide the necessary stretchability and adsorption capacity, while supramolecular polydopamine layer affords enhanced interfacial interactions. Reduced graphene oxide nanosheets and silver nanoparticle-based sensing layers offer dual electron transfer pathways. Dual encapsulations with self-healable/self-bondable ability not only mitigate the crack propagation but also protect inner conductive materials from detachment. Benefiting from these rational designs, the composite yarns exhibit a large sensing range (158% strain), high sensitivity (22.88), low detection limit (0.0345%), fast response/recovery times (105/150 ms), and remarkable robustness (enduring 10 000 cycles at 20% strain). Furthermore, pressure sensors and sensing arrays are assembled by stacking conductive yarns perpendicularly using a self-bondable function, and self-healable helical-structured conductors are fabricated through the shape-memory effect. Important applications of multifunctional yarns in physiological motion detection, gesture recognition, and circuit connection are demonstrated. This concept creates opportunities for the construction of multifunctional and high-performance wearable electronic textiles.

Abstract :
With the accelerated development of global industrialization, environmental issues, such as airborne and water pollution caused by suspended solid particulate matter (PM) seriously endanger ecosystems and human health. Fibrous filtration and separation membranes provide an effective approach to pollution treatment, yet they still face challenges in efficient and high-flux purification of highly permeable ultrafine particles. Herein, an ultrafine nanofiber-based membrane with rational hierarchical networks is designed for both air and water filtration. Through the proposed jet branching electrospinning strategy, a multiscale fiber membrane consisting of ultrafine nanofibers, medium fibers, and coarse submicron fibers is prepared. It possesses the merits of ultrafine fiber diameter, ultralow pore size, high specific surface area, and unique hybrid structure. Benefiting from these features, the obtained multiscale fibrous filter shows superior PM0.3 air filtration performance (99.96% PM0.3 removal, low pressure drop of 89 Pa) and water filtration capacity (ultrafine particle rejection efficiency of 99.50%, water flux of 9028.84 L m-2 h-1). Moreover, the controllable structure of a multiscale fiber filter also endows itself with stable and durable filtration capacity. This work may provide meaningful references for the development of high-performance filtration and separation materials.

Abstract :
ZIF-8 is considered as a promising functional material in anti-corrosion coating applications. However, ZIF-8 hydrolyzes easily, especially in acidic and salty media, due to its unstable Zn-N coordination bonding and hydrophilic crystal surface, which reduces anti-corrosion durability of the coatings. In this study, highly hydrophobic modification of ZIF-8 particles was performed through simple surface ligand exchange with 5,6dimethylbenzimidazole (DMBIM). The as-prepared ZIF-8/DMBIM particles showed high water-repellency and enhanced chemical stability in acidic, neutral, and alkaline media, and excellent compatibility and barrier function in epoxy coatings. As a consequence, ZIF-8/DMBIM modified epoxy coatings showed significantly enhanced corrosion resistances in acid, alkali and salt aqueous solutions with pH 3.0-11.0. Electrochemical impedance spectroscopy tests demonstrated that, after 20 days of immersion in 3.5 wt% NaCl solution at all the studied pH, the |Z|0.01 Hz values of ZIF-8/DMBIM modified epoxy coatings were approximately two orders of magnitude higher than of the original epoxy coatings. This work provides an idea for the development and application of ZIF materials in more fields, and innovative anti-corrosion coatings based on functional modification of materials.

Abstract :
With the increasing demand in fields such as wearable sensors, soft robotics, tissue engineering, and wound dressings, the development of hydrogels with strong adhesion in wet environments has become a critical focus of research. However, most existing adhesive materials lack the ability to transition rapidly and reversibly between the adhesive and nonadhesive states, and their adhesion is often limited to a single wet environment. In this study, a smart interfacial adhesive hydrogel with tunable adhesion properties across diverse liquid environments is presented. By tailoring interchain interactions and leveraging electrostatically induced traction between hydrophilic and hydrophobic chain segments, the hydrogel achieves reversible adhesion modulation in response to temperature changes while maintaining strong wet adhesion. Notably, its adhesive strength at elevated temperatures (45 degrees C) is approximately three times greater than at lower temperatures (5 degrees C). The adhesive hydrogel exhibits an adhesive strength of 227 kPa in aqueous environments and 213 kPa in oil-containing environments. This innovative design strategy enables the hydrogel to exhibit broad switchable, and dynamic wet adhesion capabilities, unlocking significant potential for a wide range of applications.

Abstract :
Inspired by the layered structure of dental enamel in the human body, a superhydrophobic coating with an elastic gradient was developed and placed on the inner wall of a gas transmission pipeline to reduce erosion and corrosion. The coating comprises a hard bionic superhydrophobic top coating and a hydrogel layer underneath for buffering and self-repair. To improve the impact resistance of the top coating, layered structures with different viscoelasticities were constructed by controlling the content of lauric acid (LA)@TiO2 particles and carbon nanotubes (CNTs). The amylose hydrogel underlayer not only acts as a shock absorber but also restores potential damage in the top layer, bringing an additional benefit to the corrosion resistance of the coating. Thanks to these three cooperative approaches, the coating exhibits excellent mechanical durability (800 cycles with 600-mesh sandpaper under a 49 kPa load) and corrosion resistance (with a corrosion potential of -0.21 V). Moreover, it maintains its superhydrophobicity after sanding, bending, soaking, and scratching, demonstrating its potential for application to protect transmission pipelines from erosion and corrosion.
