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 :
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 :
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 :
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 :
Durable superhydrophobic anti-erosion/anticorrosion coatings are highly demanded across various applications. However, achieving coatings with exceptional superhydrophobicity, mechanical strength, and corrosion resistance remains a grand challenge. Herein, a robust microstructure coating, inspired by the cylindrical structures situated on the surface of conch shell, for mitigating erosion and corrosion damages in gas transportation pipelines is reported. Specifically, citric acid monohydrate as a pore-forming agent is leveraged to create a porous structure between layers, effectively buffering the impact on the surface. As a result, the coating demonstrates remarkable wear resistance and water repellency. Importantly, even after abrasion by sandpaper and an erosion loop test, the resulting superhydrophobic surfaces retain the water repellency. The design strategy offers a promising route to manufacturing multifunctional materials with desired features and structural complexities, thereby enabling effective self-cleaning and antifouling abilities in harsh operating environments for an array of applications, including self-cleaning windows, antifouling coatings for medical devices, and anti-erosion/anticorrosion protection, among other areas.

Abstract :
The electrochemical urea oxidation reaction (UOR) represents a promising route to sustainable hydrogen production and reuse of urea-containing sewage. However, the efficiency of UOR is hindered by the dehydrogenation of intermediate *CONH2NH and the conversion of toxic intermediate the *CO. Herein, we report a robust strategy to elevate UOR performance by introducing iron (Fe) atoms into the Ni3S2@NiSe2 heterojunctions (denoted Fe-Ni3S2@NiSe2). The Fe-Ni3S2@NiSe2 exhibits remarkable selectivity and electrocatalytic activity towards UOR, attributed to its reconstruction into Fe-NiOOH species during UOR process, as confirmed by in-situ Raman technology. Utilizing Fe-Ni3S2@NiSe2 as both the cathode and anode in a single-chamber electrolytic cell, the hydrogen production rate reaches 588.4 μmol h−1 in simulated urea-containing sewage and 432.1 μmol h−1 in actual human urine, respectively. Notably, in both scenarios, no oxygen product is detected, and the hydrogen production efficiency surpasses that of traditional water splitting by 5.8-fold and 4.3-fold, respectively. In-situ infrared spectroscopy study reveals that the UOR process involves the cleavage of C-N bond and the generation of CO2. Density functional theory calculations further signifies that the incorporation of Fe facilitates the dehydrogenation of *CONH2NH intermediates, strengthens the d-p hybridization, and weakens O-H bonds, thereby resulting in reduced energy barriers for UOR. Our strategy holds promise for efficient hydrogen production from sewage via UOR, offering potential implications for wastewater treatment and clean energy generation. © 2024 Elsevier B.V.

Abstract :
In recent years, loading antioxidants onto inorganic nanoparticles has attracted increasing interest. However, the existing studies not only have low antioxidant loading efficiency, but also ignore the relationship between structural changes and antioxidant properties before and after antioxidant modification, greatly limiting the improvement of the antioxidant properties of composites and their application scope. In this work, we successfully prepared bis-hindered phenolic antioxidants containing silica hydroxyl groups (Bis-mAO) and loaded them onto silicon dioxide (SiO 2 ) to get the nanocomposites (Bis-mAO-SiO 2 ). The melt blending method further prepared the corresponding polyphenylene sulfide (PPS)/Bis-mAO-SiO 2 composites. The results showed that the higher antioxidant loading and more suitable antioxidant structure made Bis-mAO-SiO 2 possess excellent antioxidant properties. The prepared PPS/Bis-mAO-SiO 2 composites remained stable under high temperatures and oxygen environments. Impressively, the maximum weight loss rate temperature of PPS/Bis-mAO-SiO 2 was increased by 11.60 degrees C compared to that of PPS, and after accelerated thermal oxidation at 220 degrees C for 24 h, the relative intensity ratio between O and C of PPS/Bis-mAO-SiO 2 only increased to 0.086, much lower than 0.132 for PPS. Moreover, the viscosity of PPS/Bis-mAO-SiO 2 only increased by 29.05 % and 88.75 % after accelerated thermal oxidation at 220 degrees C for 12, 24 h. Compared, PPS ' s viscosity increased substantially by 79.22 % and 250.3 %, respectively. This meant that the Bis-mAO-SiO 2 successfully achieved a synergistic integration of high antioxidant properties and thermal stability, implying that the work offered a strategy for fabricating hightemperature resistant antioxidant composites.

Abstract :
Integration of self-healing ability and biomimetic structures into epidermal electronics is of great interest. Herein, mimicking the merits of human skin, dynamic hard domains and multidimensional conductive fillers were introduced into epidermal electronics. Firstly, aromatic disulfide bonds and H-bonds as dynamic hard domains from bis-(4-aminophenyl) disulfide and tetraethylene glycol were incorporated into polyurethane-urea (PU), and provided desired mechanical properties and self-healing capability. To enhance the strength and toughness, ZIF-67 nanoparticles with micro-pores and uncoordinated imidazole groups were introduced into PU matrix, producing excellent filler-matrix interfaces owing to the formation of high-density H-bonds and mechanical insertion. The optimized PU/ZIF-67(10%) composite exhibited high performance with a tensile strength of 4.15 MPa, an elongation at break of 1342.31 %, a toughness of 40.73 MJ m(-3), a fracture energy of 157.75 kJ m(-2), and healing efficiency of 93.25 %. Benefiting from the supramolecular PU with dynamic hard domains and multidimensional conductive fillers, the as-prepared multifunctional films exhibited excellent self-healing ability and sensing performance with a wide detection range (609 %), high sensitivity (3416.71), fast response time (65 ms), low detection limit (0.026 %), and excellent robustness (similar to 1000 cycles at 50 % strain). Different human motions and high-quality electrophysiological signals were successfully detected by the original and healable epidermal electrodes.
