Aqueous Zn–LiMn₂O₄ hybrid-ion batteries are promising for large-scale energy storage due to their high energy density, environmental friendliness, and low cost. However, conventional aqueous electrolytes suffer from two critical challenges: zinc anode side reactions and manganese dissolution from the LiMn₂O₄ cathode. To address these issues, a novel hybrid electrolyte regulated by a methylsulfonylmethane (MSM) additive is introduced. This electrolyte effectively suppresses zinc dendrite growth by promoting uniform Zn²⁺ deposition. Additionally, the modified Zn²⁺ solvation structure, with reduced water coordination, mitigates hydrogen evolution, interfacial corrosion, and by-product formation. As a result, Zn||Zn symmetric cells exhibit stable zinc plating/stripping for over 1600 h. Furthermore, MSM disrupts the tight hydrogen bonding network of the hybrid electrolyte, lowering viscosity and enhancing ion mobility, which reduces voltage polarization and improves the rate capability of Zn–LiMn₂O₄ cells. Moreover, the hybrid electrolyte stabilizes the cathode structure by inhibiting manganese disproportionation at high voltages, attributed to an increased oxygen evolution reaction overpotential and the formation of an in situ cathode-electrolyte interphase. Consequently, Zn–LiMn₂O₄ full cells achieve exceptional cycling stability, retaining 71.1% of their capacity after 800 cycles at 0.15 A g⁻¹. © 2025 Wiley-VCH GmbH.

Energy Storage materials 2025年 78卷

High-voltage and Ni-rich cathode materials are highly attractive due to their high specific energy. However, cathode-electrolyte interphase (CEI) layer often fails to adequately protect cathode materials from side reactions with electrolyte and degradation induced at the surface. In this study, we introduce an approach to construct a CEI layer that spontaneously passivate cathode surface and facilitate Li-ion transfer at the interface. This was realized by using an organofluorine borate, tris(2,2-difluoroethyl) borate (B(OCH2CHF2)3), as an electrolyte additive to facilitate CEI formation. Spectroscopic and microscopic studies demonstrated that the fluorinated borates provided superior passivation compared to traditional borates, enabling stable operation at high voltages of up to 4.5 V and elevated temperatures of 60 °C. Moreover, fluorinated borates enhanced Li-ion transfer through O-Li-F interactions, unlike conventional interface protection methods that typically cause increased interfacial resistance. A 4.5 V, 410 Wh kg-1 anode-less LiNi0.8Co0.1Mn0.1O2 (NCM811) pouch cell achieved a capacity retention of 80.1% over 120 cycles. Our findings highlight a promising strategy for spontaneous passivation of the cathode interface and enhanced Li-ion transfer for batteries with high specific energies. © 2025

Solar-driven interfacial evaporation has been regarded as a promising eco-friendly strategy for desalination, but salt deposition on evaporators limits long-term stability in practical applications. Here, we present a superhydrophobic Janus solar evaporator, namely, polypyrrole-coated polyvinylidene fluoride-modified MS (PPy-PMSP), which is fabricated through a simple dipping-drying process. The PPy-PMSP achieves high light absorption and photothermal conversion, enabling an evaporation rate of 4.22 kg m-2 h-1 in simulated seawater (3.5 wt % NaCl) under 1 sun irradiation. It also exhibits excellent salt ion rejection performance in high-salinity brine conditions and a strong purification performance for organic dyes. With simple preparation, low cost, and durability, PPy-PMSP demonstrates great potential for seawater desalination and wastewater purification. © 2025 American Chemical Society.

Fiber zinc-based batteries have emerged as a promising candidate, benefiting from zinc's natural abundance, low redox potential, high theoretical capacity, cost-effectiveness, and intrinsic safety. Despite significant progress, including the development of integrated device systems and self-powered energy textiles, fiber zinc-based batteries still encounter several challenges. Reversibility issues, such as dendrite formation and electrolyte instability, remain critical concerns, particularly frequent mechanical deformations and diverse application environments. Additionally, the complex fabrication process hinders large-scale commercialization by increasing production costs, reducing consistency, and limiting scalability. This review first presents the working principles of fiber zinc-based batteries, followed by an analysis of their design strategies and research progress.

In contrast to small molecules, macromolecules exhibit distinctive characteristics due to their higher potential energy (EP). These include elevated viscosity, enhanced tensile strength, cohesiveness, and stability. The EP of macromolecules can be modulated through the design of side groups, but this approach may also alter chemical properties. This study introduces an α-methylation strategy that significantly enhances EP without modifying the structure of these side groups. This increase in EP induces a transition in the rheological behavior of polymer systems from a rubbery to a glassy state. Concurrently, it improves hygrothermal tolerance without changing dynamic bond groups. The application of this ultra-high EP strategy results in substantial enhancements in traditional acrylic adhesives: a 1500% increase in adhesion strength and a 33200% rise in adhesion modulus when exposed to hot water. Polymer is endowed with a shape memory function due to ultra-high EP. With the dual interface locking of this function, the adhesion strength can be increased by 70%. This ultra-high EP strategy provides a possible explanation for the origin of vitrification in polymeric systems. © 2025 Wiley-VCH GmbH.

A novel photovoltaic/thermal (PVT) system using nano-enhanced micro-encapsulated PCM slurry for steam production: A numerical study

引用

International Journal of Thermofluids 2025年 27卷

As industries reliant on steam-based processes strive to reduce fossil fuel consumption and carbon emissions, interest in renewable technologies, particularly photovoltaic/thermal (PVT) systems that generate both thermal and electrical energy, is increasing. However, the limited thermal performance of PVT systems remains a key barrier. Traditional working fluids, such as water, nanofluids, and phase change material (PCM) slurries, exhibit low thermal conductivity, poor temperature regulation, and inefficient heat storage. To address these issues, a novel working fluid incorporating graphene oxide (GO) nanoparticles into microencapsulated PCM (MPCM) slurry is proposed. The integration of GO nanoparticles not only enhances the dispersion stability of the MPCM slurry but also significantly increases its thermal conductivity, leading to improved heat dissipation from PV cells. A comprehensive CFD investigation is conducted using ANSYS Fluent 2021, employing an Eulerian–Eulerian multiphase model to simulate the three-phase flow. In this model, water serves as the primary phase, while GO nanoparticles and MPCM function as secondary dispersed phases. The results demonstrate that increasing the GO volume fraction from 0 to 0.005 reduces average PV cell temperatures by up to 5°C at 40°C. Additionally, the nano-enhanced MPCM slurry achieves a thermal efficiency of 88.1 % and an electrical efficiency of 10.3 %. It is also found that using MPCM slurry as the working fluid, a 15 % volume fraction of MPCM with a melting point of 40°C achieves the highest thermal efficiency of 90.1 %, outperforming water by 20.1 % and surpassing previous studies on MPCM slurry and nanofluids. © 2025 The Author(s)

The ability of the Anterior Cruciate Ligament (ACL) to dissipate energy during cyclic loading conditions is crucial for understanding ACL failure. This study employs a novel mechanical test fixture for both shorter duration Digital Image Correlation (DIC) and longer duration Repeated Cycle-Recovery (RCR) ex-vivo experiments. The fixture ensured effective clamping and precise alignment of the Anterior Medial Bone-Ligament-Bone (AM BLB) samples while preserving the integrity and camera view of the region directly above the entheses. Results from the DIC and RCR experiments provide compelling evidence of localized hysteresis and evolving energy dissipation characteristics. The RCR experiments indicate a reduction in the energy absorption capabilities of the AM BLB with progressive cyclic loading, evident by a decrease in normalized hysteresis and diminished viscoelasticity over time. Furthermore, DIC experiments revealed strain concentrations in areas prone to acute ACL injuries. These findings underscore the importance of considering cyclic loading and localized strain behaviors in ACL failure mechanisms and may inform strategies for injury prevention and rehabilitation. © 2025, The Authors.

Extrusion-based 3D printing of thermoplastic polymers presents significant potential for bone tissue engineering. However, a key limitation is the frequent absence of filament porosity and the inherent osteoconductive properties. This study addresses these challenges by fabricating poly(lactide-co-trimethylene carbonate) (PLATMC) scaffolds with dual-scale porosity: macroporosity achieved through controlled filament spacing and microporosity introduced via NaCl leaching. The inclusion of NaCl generated rough, porous surfaces that were well-suited for dip-coating with magnesium-carbonate-doped hydroxyapatite (MgCHA), thereby imparting osteoconductive functionality. Thermal analysis revealed that salt incorporation had minimal impact on the polymer’s thermal stability. Rheological studies and computational modeling indicated that NaCl reduced the viscosity under shear, leading to enhanced printability and faster extrusion speeds. After leaching, the scaffolds exhibited approximately 34% microporosity, which significantly increased water uptake and swelling capacity, despite the roughened surfaces slightly elevating hydrophobicity. The mechanical properties of PLATMC (with nonporous filaments) and p-PLATMC (with porous filaments) scaffolds showed a modulus of elasticity of 566 ± 118 and 101 ± 20 MPa, respectively, with strain values of 178 ± 54% and 84 ± 28%. Biological evaluations highlighted the compatibility of the p-PLATMC scaffolds. Cell viability and proliferation assays confirmed sustained cellular interaction over a 14 day period. Notably, alkaline phosphatase (ALP) activity was elevated in the porous scaffolds, and the MgCHA coating significantly enhanced mineral deposition by day 28, suggesting improved osteogenic potential. In conclusion, this study presents a robust strategy for fabricating 3D-printed PLATMC scaffolds with integrated filament porosity, offering a viable platform for osteoconductive coatings in bone tissue engineering applications. © 2025 The
