In this study, we report a mechanically robust double-network hydrogel composed of polyacrylamide, polyvinyl alcohol and MXene, designed for integrated interfacial solar evaporation (ISE) and advanced oxidation processes (AOPs). The incorporation of MXene nanosheets enhances photothermal conversion and promotes efficient solar evaporation, owing to their broadband solar absorption. Remarkably, according to the DFT calculation, upon introducing ammonium persulfate (APS) as an oxidant, MXene facilitates electron transfer under sunlight irradiation, triggering the decomposition of APS and the generation of reactive oxidizing species (ROSs). This synergistic system achieves a high solar evaporation rate of 3.07 kg·m⁻²·h⁻¹ while simultaneously degrading 96.13 % methylene blue dye or 91.70 % antibiotic sulfamethoxazole within 24 h.

Herein, we initiate an electron sponge-based solid electrolyte interphase (SEI) with redox activity to solve this issue. During Zn plating/stripping, this SEI functions as a high-throughput “ion siphon” between bulk electrolyte and anode/electrolyte interface, remarkably neutralizing the negative effect of SCL. In situ Raman spectroscopy, distribution of relaxation times (DRT), and phase-field simulations strongly corroborate the “ion siphon” functionality, which is realized by adding only 2 mM K₆V₁₀O₂₈·9 H₂O (KVO) into ZnSO₄ electrolytes. Consequently, symmetrical Zn cells with redox SEIs displays evidently lowered polarization at high rates and long-term cyclability (over 1200 h at 10 mA cm⁻²/1 mA h cm⁻²).

The deprotonation process results in the more stretched chains of polyacrylic acid (PAA) in PEA(polyetheramine)/PAA, and meanwhile, the robust 3D dynamic cross-linked network is established by the electrostatic bonding of -NH₃⁺ and -COO⁻, as well as the hydrogen bonding of the donors and receptors.

Conventional energy sources, such as batteries and wired power systems, have several challenges, including limited lifespan, environmental concerns, and complex installation procedures, especially in remote agricultural environments. Triboelectric Nanogenerators (TENGs) offer a promising alternative solution for generating electrical energy by capturing low-frequency mechanical energy from available natural sources such as rain, wind and water flow. TENG operates based on the combined effect of contact electrification (CE) and electrostatic induction (EI). However, there is limited exploration of TENG in powering smart agriculture technologies. This comprehensive review discusses the working mechanism, operational modes, and material engineering strategies employed to develop high-performance TENGs, with special focus on their significance in smart agricultural technologies. Different approaches used by TENGs to harness freely available energy from agricultural environments are summarized, and related mechanisms are discussed in detail. A brief overview of the recent development of the TENG application for nitrogen fixation, crop growth promotion and agricultural environmental monitoring is discussed, and the benefits of TENG technology for smart agriculture are discussed.

LiCl electrolyte with low concentrations (≤2 M) allowed Li⁺ and Cl⁻ to form independently hydrated structures, facilitating a well-defined EDL with clearly polarized Helmholtz planes. At high concentrations (&gt;2 M), the hydrogen-bonded water network was weakened, leading to stronger electrostatic interactions between ion clusters.

Such ion pairing disrupted inner-sphere adsorption of Li⁺ onto the MWCNT surface, thereby degrading the EDL structure. These results indicate that excessive ion pairing homogenize the spatial charge distributions in the EDL, thereby weakening the piezoionic effects.

This study presents a comprehensive strategy that combines functional fillers and surface modification to enhance both the electric output performance and environmental adaptability of CBTENGs. Recycled graphitic carbon materials derived from hydrogen production are incorporated into cement matrices to optimise charge-trapping and dielectric behavior. Two cementitious surface techniques – oxygen plasma treatment and perfluorooctyltriethoxysilane (POTS) coating via chemical vapor deposition – were systematically compared. While oxygen plasma treatment introduces polar functional groups that increase hydrophilicity and suppress output, POTS coatings render the cementitious surface highly hydrophobic, significantly improving charge retention in moist conditions. The optimised CBTENG (containing 0.5 wt% graphitic carbon and a POTS coating) achieves a peak open-circuit voltage of ∼480 V and a short-circuit current of ∼3 µA, and can sustain performance in wet conditions with over 75 % output retention. Several practical applications are demonstrated, including capacitor charging, LED powering, wind-driven energy harvesting from a house roof, and pavement-based energy collection under wet traffic conditions.
