Abstract ：
Multifunctional wearable flexible electronic devices based on hydrogels have received extensive research in recent years. Despite their promising applications, a significant challenge persists in terms of efficiently powering these devices. Triboelectric nanogenerators (TENGs) assembled by surface-modified hydrogels may be one of the promising strategies to address this challenge. This study presents the development of a multifunctional composite hydrogel, which is synthesized through the amino surface modification of glycerin-cellulose hydrogel (3-aminopropyltriethoxysilane-glycerin-cellulose, A-GC). The resulting composite hydrogel is utilized in the fabrication of electrodes of TENGs, which can effectively harvest mechanical energy to power flexible sensors. By using cellulose and glycerin as primary raw materials and 3-aminotriethoxysilane as surface modification components, the composite hydrogel exhibits excellent mechanical properties, coupled with good electrical conductivity (2.83 S/m). More importantly, it exhibits a high triboelectric output performance of 205.3 V, maintains stable long-term triboelectric output, and achieves a maximum triboelectric power density of 732.1 mW/m2. Furthermore, the introduction of glycerin into the cellulose hydrogel enhances its mechanical properties and triboelectric output performance even under extreme environmental conditions (-24 and 60 degrees C). The A-GC-TENG demonstrates significant potential in various applications, including mechanical energy harvesting and conversion, writing recognition, wireless signal transmission, and human-computer interaction, showing great application prospects in flexible wearable sensors and self-powered electronic devices. The development of the composite cellulose hydrogel offers a novel approach for the fabrication of high-performance flexible wearable electronic devices, which is capable of functioning effectively in harsh environments.

Abstract ：
The in-situ generation of hydrogen peroxide (H2O2) from oxygen and water with semiconductor photocatalysts under illumination is considered as a promising synthesis pathway. However, photocarrier recombination as well as slow transfer of charges involved in carbon nitride (C3N5, CN), are the enduring challenge for photocatalytic activity. Herein, we develop a pi-stacked CN-based composites (CNv-A) coupling natural polyphenolic anthocyanins (A) with defective carbon nitride (CNv) for efficient visible-light-driven H2O2 production. The strengthening pi-stacking (CNv-A) leads to extended electronic transmission networks via effective intermolecular pi-pi interactions, resulting in a high H2O2 generation rate of 147.2 mu mol.L-1.h-1, as well as 42 times that of the pristine CN. The combination of experimental results and theoretical calculations reveals that with the incorporation of anthocyanins, the intermolecular pi-pi stacking reconstructs the enlarged charge transfer networks over carbon nitride, thus facilitating electron transfer and active center dot O2- generation. Moreover, increasing the content of nitrogen vacancy of carbon nitride effectively strengthened the pi-pi interactions, accelerating the transfer and separation of charge carriers, thereby achieving drastic high-performance H2O2 production via an indirect single-electron oxygen reduction reaction (ORR) pathway. This work provides a new perspective for regulating charge transfer and separation by modulating the strength of intermolecular weak interactions.

Abstract ：
Photocatalytic CO2 reduction into high-value C2+ products such as C2H6 is of great importance but challenging due to their multi-electron steps and high energy barrier of C & horbar;C coupling. Moreover, improving its solar-to-chemical (STC) energy conversion efficiency in pure water beyond the current 1% empirical value is also a significant challenge. Herein, graphite carbon nitride (g-C3N4) nanosheets with controllable carbon (C) doping and nitrogen (N) vacancies (PCCN-x) are designed through a biochar-tailored protocol for efficiently and selectively photo-converting CO2 into C2H6. The optimal PCCN-10 photocatalyst enables the achievement of an exceptional C2H6 activity of 99.14 mu mol g(-1) h(-1) with C2H6 selectivity of 80.33% over 20 h in pure water. A record STC efficiency of approximate to 1.13% for solar fuel production from CO2 and H2O vapor is also achieved without any other energy inputs. Outdoor tests also demonstrated an impressive CO2-to-C2H6 photo-conversion rate of 43.17 mu mol g(-1) h(-1) in pure water, with stable activity over 50 h period. Critically, experimental and theoretical calculations further confirm the pivotal role of bridged C sites and N vacancies in activating CO2 molecules and promoting the formation of C & horbar;C coupling intermediate (*OCCO), which is very beneficial for the production of C2H6. The impressive performance of this work in the photocatalytic conversion of CO2 to high-value C2H6 fuels paves the way for large-scale fuel production and broader sustainable applications.

Abstract ：
Nanofluidic membranes composed of polymers and metal-organic frameworks (MOFs) are considered ideal for efficiently harvesting salinity gradient energy from global estuaries due to their well-defined nanochannels and surface charge. However, developing a polymer/MOF membrane that simultaneously combines excellent mechanical strength, scalability, high surface charge density, and porous structure remains a significant challenge. Here, we demonstrated a hybrid nanofluidic membrane by deconstructing charged cellulosic fibers (CCF) into charged cellulose molecules (CCM) and then tandemly connecting imidazolate molecular sieve framework-8 (ZIF-8). In this regard, the CCM/ZIF-8 nanofluidic membrane inherits a high surface charge density of CCF (-44 mV for zeta potential), abundant-angstrom/nanopore distinction of ZIF-8 (1540.5 m(2)/g for specific surface area and sub-nanometer pore size), and thus demonstrates excellent chemical and structural uniqueness, and superior robustness (similar to 25 MPa), high stability (stable for over 30 days in acidic, alkaline, and seawater environments) and scalability. As a result, our CCM/ZIF-8 membrane enables an excellent cation selectivity (t(+) of 0.82) and correspondingly high power density of up to 8.7 W/m(2) in KCl system (0.01/0.5 M salinity gradient, testing area of 0.075 mm(2)) and stably output over 60 days. This study provides a promising strategy for constructing high-performance polymer/MOF nanofluidic membranes for advanced selective ion transport, beyond salinity gradient energy conversion.

Abstract ：
Hydrogen peroxide (H2O2) photosynthesis from oxygen and water has become an attracting route due to its green, low-carbon and sustainable features. Although carbon nitride (CN) is a remarkable semiconductor for photocatalytic H2O2 production, CN also suffers from slow transfer and poor separation efficiency of photogenerated charges due to the intrinsically molecular structures. Herein, we report a facile method to enhance H2O2 evolution with asymmetric CN via molten-salt assisted supramolecular assemblies of melamine and 2,4,6triaminopyrimidine (T). The optimum M-CNT exhibited a photocatalytic H2O2 production rate of 44.63 mu mol center dot L- 1h- 1, which is more than 4 times higher than that of pristine CN without any sacrificial agents. Experimental and DFT results demonstrate T molecule can tune the charge location of CN frameworks, promoting electron transfer and efficient separation. Furthermore, under the synergy of molten salt, the uneven distribution of intramolecular charges can be exacerbated to boost the photocatalytic performance through significant polarization effects. This work provided a paradigm of charge characteristics of carbon nitride via asymmetric molecular engineering for enhanced photocatalytic H2O2 generation.

Abstract ：
Transparent flexible heaters attract great attention due to their potential applications in smart windows, wearable electronics, hand warmers, etc. Here, we present a highly flexible cellulose/zinc oxide/indium tin oxide (CZI) film heater, which was prepared by spinning coating of zinc oxide (ZnO) solution on cellulose film followed by magnetron sputtering of indium tin oxide (ITO). The CZI film exhibits a high visible light transmittance (80.3%), low resistance (7.3 Omegasq-1), and good thermostability. As connected to the circuit, the CZI film showed an excellent Joule heating performance even after multiple repeated bending tests. The temperature of the CZI film could increase from room temperature to 89 degrees C within 2 min under the working voltage of 6 V. Prompted by these versatile properties, and we demoed the application scenarios of this CZI film heater in thermochromism, deicing, and defogging to enlighten for the application of this film material in sensors or smart windows.

Abstract ：
Most hydrogels rely heavily on cryoprotectants to enhance their anti-freezing capabilities; however, this approach is often accompanied by disadvantages such as altered network structures and the risk of cryoprotectant leakage in aqueous conditions. Given these challenges, an environmentally resilient diode-like hydrogel is developed, featuring a double-layer coating design inspired by the physiological characteristics of penguins. This design is achieved through plasma treatment and immersion in 3-aminopropyltriethoxysilane/butyl acetate and perfluoropolyether carboxylic acid/butyl acetate solutions, constructing a double-layer coating with stable interfacial strength. The coating not only enhances anti-dehydration performance but also imparts anti-freezing properties via N,N-dimethylformamide solution. By carefully regulating the coating thickness and polymerization duration, it has optimized the mechanical and electrical attributes of hydrogel, culminating in robust performance even at -80 degrees C. The hydrogel exhibits exceptional water retention capabilities, with a mere 33.4% water loss rate following 7 days of air drying. Moreover, the hydrogel demonstrates stable piezoionic output performance across various low-temperature environments, with tensile and compressive strengths of 1156 kPa and 3.45 MPa, respectively. This study presents a novel solution for the application of conductive hydrogels in smart wearable devices, underscoring their potential for use in extreme environments.

Abstract ：
With the backdrop of the rapid advancement in supercapacitor technology, biomass hydrogel electrolytes have emerged as a prominent research focus. This study systematically optimized critical parameters using a multi-component synergistic strategy, the glycerol (Gl) as an antifreeze agent, to develop a ligninsulfonate (LS) dual-network antifreeze hydrogel suitable for low-temperature-resistant supercapacitors. The P(AA-co-AM)/LS/Al3+/Gl hydrogel exhibited remarkable mechanical properties, with tensile stress reaching 751.01 kPa and strain of 1050 %. The assembled supercapacitor demonstrated a specific capacitance of 244.5 F g−1 at room temperature under a current density of 0.2 A g−1. After 5000 charge-discharge cycles, the capacitance retention rate remained 80.16 %, with a coulombic efficiency exceeding 98.5 %. Moreover, at −80 °C, the hydrogel assembled supercapacitor achieved a specific capacitance of 167.2 F g−1; retaining certain electrochemical performance across various bending angles. This research provides valuable insights into the development of biomaterial-based antifreeze electrolytes for extreme environments. © 2025 Elsevier Ltd
