Progress in commercializing solid polymer electrolytes (SPEs) for lithium metal batteries (LMBs) has been impeded by challenges, like concentration polarization, non-uniform Li+ flux, and an unstable solid electrolyte interface (SEI), which contribute to dendrite formation. To address these issues, silica framework (SF)-based single-ion conductors are proposed, featuring a unique solvation channel composed of a fluorinated segment, a high-dipole zwitterion, and a rotation-motion-driven ion-hopping medium. This design promotes low resistance at the cathode/electrode interface, suppresses dendrite growth at the anode/electrolyte interface, and maintains a uniform Li+ flux. This results show that continuous ion channels within a robust framework enhance Li-ion dissociation and transport, achieving high ionic conductivity (σDC = 8.8 × 10−4 S cm−1), a modulus of 0.9 GPa, a high lithium transference number (≈0.83), and an extended electrochemical stability window (up to 5.2 V) at 25 °C. This design fosters the formation of a hybrid organic/inorganic SEI layer composed of Li2CO3, LiF, and Li2O, enabling ultra-stable Li plating/stripping for over 4000 h at 0.1 mA cm−2. Furthermore, the full cells demonstrate excellent rate performance and long-term cycling stability and capacity retention (81% for Li||LFP and 86% for Li||NCM811 after 400 cycles at 1 C) and high coulombic efficiency, offering a promising strategy to stable LMBs. © 2025 Wiley-VCH GmbH.

Solid-state electrolytes (SSEs) hold significant potential for advancing lithium metal batteries (LMBs) by enhancing safety through the replacement of liquid electrolytes. However, challenges such as low ionic conductivity, limited electrochemical stability, and poor electrolyte/electrode interface compatibility hinder the development of high-energy-density LMBs. Herein, a strategy for designing SSEs is proposed using multiple-bridge engineered composite elastomer electrolytes (CEEs) that incorporate ion-rotating dipole interactions, ion-anchoring dipole interactions, and hydrogen bonding, along with a CEE-based composite elastomer cathode (CEC). This design combines a volume-adaptive elastomer matrix, a high-Li+ conducting deep eutectic electrolyte, and robust nanowires. The resultant CEE exhibits high ionic conductivity (1.7 × 10−3 S cm−1), a lithium transference number of 0.72, and a wide electrochemical stability window (up to 4.9 V) at 298 K. The engineered uniform Li+ flux also promotes stable Li plating/stripping for over 900 h at 0.1 mA cm−2. Furthermore, the LFP-based CEC|CEE|Li full cells deliver a reversible capacity of 133 mAh g−1 with 95% retention after 300 cycles in coin cells, and 129 mAh g−1 with 96% retention after 250 cycles in pouch cells at 1 C. This strategy presents a promising approach for designing solid-state polymer electrolytes to extend the lifespan of high-energy-density LMBs. © 2025 Wiley-VCH GmbH.

Increased consumer awareness of animal welfare and environmental sustainability has driven the development of vegan leather alternatives to natural leather. Fossil-derived leather substitutes offer superior strength and thermal stability but often lack biodegradability, carbon neutrality and aesthetics. Biorenewable alternatives are more eco-friendly but typically suffer from insufficient thermal and mechanical properties and poor moisture resistance. This study presents the synthesis of mechanically reinforced, thermally enhanced and biodegradable poly(ester amide)s (PEAs) incorporating hydrogen bonds as vegan leather coating materials. Synthesized from biobased 1,4-butanediol, adipic acid and nylon 46 via a two-step transesterification/polycondensation process, the resulting PEAs exhibit over eight times higher tensile strength, 3-fold greater toughness, and enhanced thermal stability compared to their constituting homopolymers, poly(butylene adipate) and nylon 46. All PEAs disintegrate within 18 weeks and achieve over 60% biodegradation rate relative to cellulose under composting conditions within one month. When applied to mushroom fabrics, the PEA coating provides haptic sensations (slipperiness and softness) comparable to commercially available leather. Life-cycle assessment indicates that PEA-coated leather imposes considerably lower environmental impacts than both bovine and polyurethane-based leather. This novel material holds promise as a sustainable, high-performance vegan leather substitute. © 2025 American Chemical Society.

Cultured meat offers a sustainable alternative to animal farming, with the potential to reduce environmental impacts and improve food security. However, recapitulating natural meat marbling remains a significant challenge. This study presents a straightforward technology for achieving precise marbling patterns in large-scale cultured meat using self-healing hydrogels containing boronic acid-conjugated chitosan. Unlike conventional hydrogels, which require nonphysiological conditions for strong, reversible bonding, our system achieves robust reversible bonding at neutral pH through a unique mechanism: the nucleophilic groups of chitosan facilitate boronic acid-diol bond formation, exhibiting half the strength of a typical covalent bond, as demonstrated by nanomechanics analysis. The hydrogels form dual reversible networks of boronic acid-diol and hydrogen bonds, enabling self-healing and tunable stiffness. Biocompatibility studies confirm that they support the growth of mouse-derived cells and bovine-derived primary muscle cells. Each hydrogel variant optimizes mechanotransduction for the distinct requirements of fat or muscle cell culture and differentiation. This self-healing scaffolding technology enables the seamless assembly of muscle and fat monocultures into centimeter-thick meat with micrometer-scale marbling patterns, tailoring organoleptic properties and nutritional profiles without the need for meat glues or processing equipment. © 2025 The Authors.

Increased biodegradability, in other words reduced environmental recalcitrance, has the potential to be an important asset in the battle against plastics pollution. It can partially mitigate global plastic leakages into the environment, which is next to their impact on climate change the biggest concern regarding plastics use. Biodegradation should be regarded as an optimal safety net in many applications and should often not be the targeted waste management option for biodegradable plastics. Biodegradability should not preclude reuse or proper recyclability, which are impactful means to reduce the carbon intensity of plastics lifecycles. Despite the added advantages, the market penetration of biodegradable plastics is only very slowly growing. Moreover, policy recommends its use only in limited applications, driven by sometimes-higher cost and limited recyclability. In this article, we posit that arguments against widespread application of biodegradable plastics are largely driven by misperceptions arising from intrinsic limitations of contemporary sustainability assessments and offer an alternative viewpoint that could compensate for this. In general, sustainability assessments fail to properly assess learning curves, often do not take littering potential into account, and are rather conservative with respect to background systems. Hence, recyclability– or better: circularity– judgements often do not resolve the paradoxical situation in which increased market shares lead to easier and more profitable recycling schemes and vice versa. Judging disruptive innovations by incorporating thermodynamics-inspired, less data-intensive, state-based methods, based on, e.g., statistical entropy analysis, into the decision support framework could allow to forecast packaging markets with performant materials that are intrinsically circular, having reduced environmental recalcitrance. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

Electrospun biodegradable fibers have been attracting significant attention in various applications. Introducing a porous structure into these fibers enhances their surface area and thus extends their applications. Here, we report a facile route to produce a highly hierarchical porous fiber structure from biodegradable electrospun solid poly (L-lactic acid) (PLLA) fibers by acetone-induced swelling-crystallization. By controlling the concentration of acetone solution and immersion time, the highly hierarchical porous PLLA fiber membrane with a very large surface area of 138.06 m2 g−1 and a high pore volume of 0.593 cm3 g−1 was fabricated. Furthermore, we demonstrated that the porous PLLA fiber membrane presented a high oil adsorption capacity of up to 27.0 g g−1, surpassing the performance of solid electrospun PLLA fiber membranes by approximately 34 %. The highly oil-adsorptive porous PLLA fiber membrane outperformed many conventional porous materials. Therefore, the hierarchical porous PLLA fiber membrane has high potential as an eco-friendly material for high-oil adsorption applications. © 2025 The Korean Society of Industrial and engineering Chemistry

This study investigated the physicochemical properties of submicron atmospheric particles using an advanced drone-based system integrating a miniaturized real-time concentration measurement module and a surface-enhanced Raman spectroscopy-based single-particle analysis platform. This system enables vertical profiling of particle size distributions down to 20 nm and chemical characterization of submicron particle mixing states at ground level and aloft, capabilities beyond conventional Raman microspectrometry. Field campaigns were conducted in urban (Incheon) and semi-urban (Dangjin) environments to examine how aerosol composition and mixing states vary with altitude and location. In Incheon, although total submicron particle number concentrations were similar on the low- and high-pollution days, the latter exhibited a higher proportion of larger particles, resulting in elevated mass concentrations and degraded air quality. Internally mixed particles comprised 75.8 % at ground level and 54.5 % aloft, with nitrate-containing particles increasing from 36.2 % to 67.4 % at ground level and from 31.4 % to 77.2 % aloft under stagnant conditions. In Dangjin, high relative humidity (∼80 %) promoted secondary organic aerosol (SOA) formation and increased mixing complexity. On the more humid day, the SOA-containing particle fraction rose to 51.2 % at ground level and 29.2 % aloft, compared to ∼13 % on the less humid day. These results demonstrate that meteorological conditions, particularly humidity and atmospheric stability, critically influence particle composition and transformation. The integrated measurement system and resulting observations provide a representative picture of submicron aerosol behavior under real-world conditions, highlighting the robustness and potential of this approach for vertical aerosol characterization. © 2025 Elsevier B.V.

Persulfate-based advanced oxidation processes have emerged as promising technologies for mitigating endocrine-disrupting chemicals (EDCs) in wastewater treatment. Economically viable Fe-based materials with tailored properties have demonstrated significant efficacy in activating persulfate for the decomposition of EDCs through both radical routes (∙OH, SO4∙−, and O2∙−) and non-radical routes (1O2, surface activated PS complex, and high-valent Fe species). This review summarized the latest advancements in the persulfate activation mechanisms mediated by Fe-based materials, categorized by Fe valence states and the types of reactive species. Furthermore, it critically assesses the influence of active sites of Fe-based catalysts on persulfate activation pathways and summarizes the selective reaction of reactive species towards EDCs. Despite these advancements, several challenges persist in non-radical route-dominated persulfate activation, particularly regarding the impact of Fe-Fe distance on the reactive species and the catalytic role of Fe-based materials for reactions between inorganic ions and persulfate. This review proposes prospective research directions, provides design strategies, and expands the application of Fe-based materials in PS activation for effective EDC abatement in real situations. © 2025 Elsevier B.V.

Valorization of agricultural biowastes to biosorbents provides an excellent opportunity to recycle these wastes into valuable products and filtration of contaminants, especially potentially toxic trace elements in aquatic ecosystems. Water contamination with potentially toxic trace elements is a widespread global issue. Various agricultural biosorbents have been tested to remove trace elements from wastewater. Despite abundant research, there are scarce studies regarding the critical data analysis on trace elements removal efficiency by agricultural biowastes under various conditions. This review critically delineates the data analysis of recent literature published from 2018 to 2024 for a critical comparison of different agricultural biosorbents and the applied conditions to remove trace elements from aqueous media. Data analysis (based on 1188 observations) revealed that the mean trace element removal by agricultural biowaste-derived biosorbents from contaminated water was 75 %, ranging from 2 to 100 %. The most frequently reported removal efficiencies of agricultural biosorbents were 90–100 %. Notably, few agricultural biosorbents such as banana peel demonstrated the highest removal efficiency of 97 %, followed by cassava peels at 92 %, emphasizing the significance of recycling these materials for sustainable trace element removal from wastewater. Data analysis revealed that the trend for trace element removal from wastewater follows a descending order, with zinc exhibiting the highest removal rate at 81 %, followed closely by lead at 80 %. This trend continues with arsenic at 75 %, nickel and cadmium both at 70 %, and so forth. Thus, agricultural biosorbents play a pivotal role in this process, showcasing their potential in waste valorization and environmental remediation. Hence, the present review article is expected to contribute towards the comparative efficiency of various agricultural biosorbents, and the selection of the best biosorbents, depending on appl

The increasing CO2 concentration in the atmosphere has substantial impacts on the global temperature. For energy sustainability and minimization of the effects of global warming, an approach to understand CO2 capturing and a carbon neutral culture is extremely essential in the present circumstances. The CO2 emission from vehicles and industries can be minimized using energy cost-effective techniques and can be converted more selectively into reusable fuels via thermochemical, electrochemical, photochemical, photocatalytic, electrocatalytic, biological and inorganic carbonate-based approaches. In this review article, we have discussed the effects of increased global temperature on human beings, economy and climate change. Further, we have discussed the photocatalytic conversion of CO2 (PC-CO2) into gaseous and liquid fuels under solar light driven photocatalysis. The adsorption and activation of CO2, its conversion into various intermediates, their stability and selectivity of the final products have been elaborated comprehensively. The conversion mechanisms of CO2 into CO, CH4, alcohol, aldehyde and carboxylic acid have been discussed in detail. The role of defects and exposed facets of photocatalysts, effect of metal and non-metal dopants, and the additive role of co-catalyst on the mechanisms and selectivity of the conversion products have been discussed comprehensively. Finally, future perspective is discussed to highlight the research gap in the PC-CO2. We hope that this article will help to understand the mechanisms of PC-CO2 and will direct researchers to add their role in the reduction of CO2 to control global warming and make life easier on earth in the coming years. © 2025 Elsevier B.V.
