Bridge networks are essential components of civil infrastructure, supporting communities by delivering vital services and facilitating economic activities. However, bridges are vulnerable to natural disasters, particularly earthquakes. To develop an effective disaster management strategy, it is critical to identify reliable, robust, and efficient indicators. In this regard, Life-Cycle Cost (LCC) and Resilience (R) serve as key indicators to assist decision-makers in selecting the most effective disaster risk reduction plans. This study proposes an innovative LCC–R optimization framework to identify the most optimal retrofit strategies for bridge networks facing hazardous events during their lifespan. The proposed framework employs both single- and multi-objective optimization techniques to identify retrofit strategies that maximize the R index while minimizing the LCC for the under-study bridge networks. The considered retrofit strategies include various options such as different materials (steel, CFRP, and GFRP), thicknesses, arrangements, and timing of retrofitting actions. The first step in the proposed framework involves constructing fragility curves by performing a series of nonlinear time-history incremental dynamic analyses for each case. In the subsequent step, the seismic resilience surfaces are calculated using the obtained fragility curves and assuming a recovery function. Next, the LCC is evaluated according to the proposed formulation for multiple seismic occurrences, which incorporates the effects of complete and incomplete repair actions resulting from previous multiple seismic events. For optimization purposes, the Non-Dominated Sorting Genetic Algorithm II (NSGA-II) evolutionary algorithm efficiently identifies the Pareto front to represent the optimal set of solutions. The study presents the most effective retrofit strategies for an illustrative bridge network, providing a comprehensive discussion and insights into the resulting tactical approaches

Transforming Industrial Waste into Amine-Functionalized Mesoporous Materials Using Alkali Fusion-Hydrothermal Method for environmental Humidity Control Applications

引用

Waste and Biomass Valorization 2025年第1期16卷 271-280页

作者： Lin, Ya-Wen Lin, Kae-Long Kuo, Bo-Yi Chen, Yu-Hao Bachelor Program for Fire and Safety Science Da-Yeh University 168 University Rd Dacun Changhua515006 Taiwan Department of Environmental Engineering National Ilan University Yilan City260 Taiwan

This research utilizes the rich SiO2 and Al2O3 sources in light-emitting diode waste quartz sand (LEDWQS) and granite sludge (GS) through alkali fusion and hydrothermal method as the precursor of synthetic mesoporous humidity control material (MHCM). The effect of adding amine functional groups on the amine functionalized mesoporous humidity control material (AF/MHCM) was also discussed. The results show that the crystalline phase and surface composition of MHCM are consistent with typical MCM-41 characteristics. The specific surface area of AF/MHCM was 29.91m2/g. The results confirm that the amine functional groups have been effectively modified on the pore surface, and the nitrogen adsorption-desorption isotherm of AF/MHCM has changed from type IV to type II. In addition, this study also proves that AF/MHCM has excellent humidity control performance, with a moisture adsorption–desorption performance of up to 63.36 g/m2, which is in line with the Japanese Industrial Standards for humidity control building materials (moisture adsorption–desorption performance > 29 g/m2). AF/MHCM synthesized by reused waste derived from the manufacturing process of electronic and electrical equipment as raw materials has excellent humidity control performance, and the result can be used as a smart indoor humidity control material in various construction applications. © The Author(s), under exclusive licence to Springer Nature B.V. 2024.

Indonesia lacks an established waste pre-collection system resulting 90% waste ending up in open-dumping site. This study identifies a 35-m radius per drop-off points as the most optimal model. The City of South Tangerang, on 21 residential areas with a population of 63,157, being examine. Utilizing ArcGIS Pro and Python scripting, 12 scenarios were developed, model drop-off radii of 15–45 m and household limits of 4–32 per drop-off point, including combined models. Spatial clustering KD-Tree algorithm and Proximity-based Routing were employed to determine collection placements and walking distances. Heatmap and ANOVA tests evaluated conformity with residential characteristics. Model then organized into eight frequency schemes, utilizing motorcart and handcart systems with 4-day and 2-day pickup schedules for waste bank and in-house compost programs. This optimized model reduces collection time by up to 81% and costs by 50% compared to traditional door-to-door systems, achieving cost reductions of $30–$38 USD per ton and lowering CO₂ emissions. The discussion covers opportunity costs and occupational risk. This approach supports Indonesia’s waste reduction targets and offers policy alignment for urban waste management. © The Author(s), under exclusive licence to Springer Nature Japan KK, part of Springer Nature 2025.

Fluorinated Functional Units for Li+ Flux Homogenization in Silica Framework-Based Zwitterionic Single Ion Conductors for Stable Lithium Metal Batteries

引用

Advanced Energy Materials 2025年第0期

作者： Handayani, Puji Lestari Yun, Susung Kim, Gihyeon Choi, U Hyeok Department of Polymer Science and Engineering and Program in Environmental and Polymer Engineering Inha University Incheon22212 Korea Republic of

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.

Ion-Anchoring Dipole-Integrated Composite Elastomer Electrolyte and Cathode for High-Performance Lithium Metal Batteries via Multiple-Bridge engineering

引用

Advanced Energy Materials 2025年第0期

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.

引用

Journal of Water and Climate Change 2025年第4期16卷 1443-1458页

作者： Mizyed, Amjad Mogheir, Yunes Hamada, Mazen S. Water Technology joint program Islamic University of Gaza al-Azhar University of Gaza Gaza Palestine Water Resources and Environment – Civil and Environmental Engineering Islamic University of Gaza Gaza Palestine Chemistry Department – Faculty of Science Al Azhar University Gaza Strip Palestine

The agricultural sector in the Gaza Strip consumes more than 51% of the available water, leading to a massive deficit in the water budget. This study employs the water footprint concept as an innovative tool for effective water resources management. It examines the impact of several factors on nine basic crops (olives, citrus, grapes, wheat, tomatoes, potatoes, eggplant, squash, and cucumber) in the aspects of irrigation water consumption, climate parameters, crop patterns, virtual water trade, and achieving the best profits using the CROPWAT program and developing a linear programming model that combines economic benefit and water footprint. The best optimization was attained by changing crop pattern cultivation, as it achieved food security and optimized by 33% the use of green water. Also, the consumption of blue water was reduced by 29.4 million m3 (37%), as well as the productivity of water units increased to 18.5 $/m3 for eggplant, followed by potatoes at 13.9 $/m3, tomatoes at 9.25 $/m3, and cucumbers at 8.74 $/m3. The water footprint has proven its effectiveness in increasing water use efficiency and is considered an effective tool in planning for sustainable water management. © 2025 The Authors.

Increasing evidence is showing that per- and polyfluoroalkyl substance (PFAS) replacing compounds are not as safe as they were assumed. This study investigated the plant uptake of two most prevalent PFAS, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic (PFOS) and their replacing compounds, hexafluoropropylene oxide dimer acid (HFPO-DA or GenX) and 6:2 chlorinated polyfluoroalkyl ether sulfonates (Cl-PFESAs) (6:2 Cl-PFAES) by hydroponically grown lettuce in the presence of different nitrogen fertilizers including ammonium sulfate ((NH4)2SO4), potassium nitrate (KNO3), and urea in a growth chamber. Interestingly, (NH4)2SO4 significantly increased GenX uptake in lettuce shoots by ∼108% and KNO3 increased the uptake of PFOS and 6:2 Cl-PFAES by 267% and 395%, respectively, suggesting that the nitrogen fertilizer type has a marked impact on the plant uptake of PFAS and that this impact was PFAS-dependent. Our results also showed that (NH4)2SO4 generally resulted in higher PFAS root to shoot transfer than the other two types of nitrogen fertilizers. Metabolomic analysis revealed that amino acids, nucleotides, and antioxidants are the major metabolites that were either significantly increased or decreased in the lettuce shoots. These results showed that nitrogen fertilization management can have a significant impact on PFAS plant uptake and transport, and the impact depends on the types of nitrogen fertilizer and PFAS compounds. © 2025 The Authors.

Increasing air temperatures are driving permafrost warming across the Arctic and sub-Arctic. This in turn degrades the geomechanical properties of soils, disrupts the natural environment and infrastructure systems, and results in long-lasting societal impacts. Understanding the thermal state of degrading permafrost in the Arctic is crucial for maintaining resilient infrastructure in the changing Arctic. This study employs Distributed Temperature Sensing (DTS) to monitor permafrost temperature near Utqiaġvik, Alaska, from 2021 to 2024. Fiber-optic DTS sensors have unique and attractive characteristics that allow their deployment in the Arctic for low-maintenance, cost-effective, and high-resolution data. This paper presents the temperature recordings of a 2-km DTS system on the tundra near Utqiaġvik, Alaska, by the Elson Lagoon. A hysteresis model is developed to link permafrost temperature with air temperature, incorporating meteorological data and ground surface conditions. The study also explores the impact of civil infrastructure on permafrost thermal dynamics. © ASCE.
