Moreover, owing to the lack of an internally consistent thermodynamic database for MgO-MgCl<ce:inf loc=\"post\">2</ce:inf>-H<ce:inf loc=\"post\">2</ce:inf>O-MA systems, these coupled effects have not been systematically elucidated from a thermodynamic perspective. To address this gap, we develop a self-consistent thermodynamic database and integrate it into a thermodynamic framework for predicting phase assemblages in hardened MOC pastes. The predictions are validated against literature-reported and newly obtained XRD data. Results show that active MAs, including silica fume, fly ash, slag, metakaolin, and carbide slag, chemically interact with MOC and promote M-(A-)S-H formation, whereas C-(A-)S-H formation is not observed within the investigated compositional range. In contrast, inert MAs (CaCO<ce:inf loc=\"post\">3</ce:inf> and CaSO<ce:inf loc=\"post\">4</ce:inf>·2H<ce:inf loc=\"post\">2</ce:inf>O) mainly act as microstructural densifiers without altering the hydration products.

A market-oriented environmental impact assessment is presented for a novel method for recycling Ti6Al4V machining chips into atomization electrode feedstock. The recycled alternatives demonstrated similar properties to commercial variants, both in powder form and in parts printed using Laser Powder Bed Fusion and Composite Extrusion Modeling. Environmental analysis revealed substantial gains, largely driven by reduced reliance on energy-intensive titanium sponge production. Substituting the Ti6Al4V sleeve, essential for electrode fabrication, with a stainless steel variant decreased CO<ce:inf loc=\"post\">2</ce:inf>-eq by 33.2%. The sponge market dominance of China, Japan, and Russia, with their fossil-dependent electricity generation, prevented leveraging a green energy mix, as evidenced by a modest 14% decline in the greenhouse effect associated with electrode fabrication despite a fivefold increase in renewable energy share. Assuming 60% scrap integration in the Ti6Al4V sleeve, the chip-based electrode's cumulative energy demand and CO<ce:inf loc=\"post\">2</ce:inf>-eq decreased by 66.6% and 70.8%, respectively, compared to the commercial electrode with a similar scrap-to-sponge ratio. The process could save between 31.31MJ and 131.04 MJ per 1 kg of remelted ingot, considering material losses in the titanium value chain. Short-term market disruption from the developed process is unlikely, but the additive manufacturing expansion would drive long-term shifts in scrap and sponge demand. Amid a titanium market badly shaken by the Russia-Ukraine war, this study reveals a path to greener, cheaper titanium powder production; an insight for decision-makers striving for resilience in aerospace and additive manufacturing.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"5 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148884018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, defining and assessing URI remain challenging, and its sustainable development implications, particularly regarding specific sustainable development goals (SDGs), remain insufficiently articulated. This study distinguishes Urban-Rural Comprehensive Development (URCD) and Urban-Rural Equalized Development (URED) as two analytically distinct dimensions of URI, operationalized through the production, living, and ecological functions of urban-rural systems. Across prefecture-level cities in Northeast China (2000–2020), it examines their spatiotemporal evolution, barrier factors and interactions, and differentiated SDG profiles. The results reveal that: (1) URI exhibited a consistent upward trend, yet URCD and URED followed divergent trajectories — URCD rose from a level well below URED, increasing by 89%, while URED grew by only 0.99% — producing a characteristic V-shaped gap. Functional contributions followed the order EF > LF > PF across both dimensions. Spatially, core cities led in comprehensive prosperity but lagged in equalization, while peripheral cities displayed the opposite pattern. (2) Barrier factors constraining URI comprised enhancing, attenuating, and volatilizing types, with enhancing and attenuating factors counterbalancing each other and volatilizing factors modulating their dynamics. Factor interactions were predominantly bivariate-enhancing. URCD constraints exhibited pronounced functional differentiation, whereas URED constraints remained diffusely distributed across all functions. (3) SDG decomposition yielded contrasting structural profiles across both URI dimensions — divergent, with economic targets exceeding ecological and governance targets, under URCD and balanced but level-limited under URED — with synergistic intensity declining under both.

However, conventional NCI is “ex-post” calculated from real-time or post-consumption system states, whereas geographically dispatchable loads (GDLs) must plan where and when to operate before the corresponding carbon conditions are realized. Renewable generation variability can further change nodal carbon conditions during this decision lead time. Consequently, a decision-ready NCI signal at the horizon and spatial-temporal granularity required for proactive GDL scheduling remains insufficiently established. To address this gap, this paper presents a proactive “ex-ante” spatial-temporal carbon response framework. At its core, we develop a novel deep learning-based hierarchical network, enhanced by a dual-stage attention mechanism and a large language model (LLM)-based multi-agent cooperation system to accurately forecast day-ahead NCI. This design effectively mitigates the impact of renewable energy uncertainty and enhances predictive resilience. On the demand side, the framework proposes a spatial-temporal carbon scheduling model that integrates geographically dispatchable loads (GDLs), including mobile energy storage systems (MESSs) and distributed data centers (DDCs). Leveraging high-accuracy day-ahead NCI predictions, the framework can effectively reduce system emissions by quickly responding to carbon intensity fluctuations. On a modified IEEE 33-bus system, the agent-assisted hierarchical forecasting model achieves a mean absolute percentage error of 9.483%. Relative to ex-post scheduling, predicted NCI advances the representative charging and discharging actions of MESS by approximately one hourly interval. Separately, under the ex-ante setting, enabling spatial-temporal GDL flexibility reduces calculated emissions by 33.86% relative to the case without such flexibility. These results show how predictive nodal carbon signals can be translated into proactive scheduling, supporting a shift from passive carbon accounting toward proactive carbon management.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"14 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148883978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing planning methods predominantly focus on an idealized future dominated by green hydrogen while overlooking the practical need for a balanced selection of diverse hydrogen production technologies in real-world applications. Moreover, they fail to comprehensively address uncertainties across multiple planning stages, particularly the distinct impacts of short-term operational variability and long-term policy evolution. To address these challenges, this paper proposes a multi-stage low-carbon planning framework for H-MEMGs considering multiple hydrogen production technologies and hybrid uncertainty risks. The proposed framework enables the endogenous selection and capacity expansion of gray hydrogen, blue hydrogen, and green hydrogen technologies across multiple planning stages, while coordinating renewable generation and energy storage resources. To address uncertainties with different temporal characteristics, a Wasserstein-based distributionally robust joint chance constraint is employed to capture short-term renewable generation uncertainty, and information gap decision theory is integrated to quantify the robustness of planning decisions against long-term decarbonization pathway deviations. Furthermore, a tailored bilinear Benders decomposition algorithm is developed to efficiently solve the resulting mixed-integer optimization problem. Numerical case studies demonstrate that the proposed method can effectively reduce carbon emissions by approximately 26.9% compared with the carbon-unconstrained benchmark, while enabling adaptive hydrogen production technology selection under evolving carbon emission restrictions. Compared with fixed hydrogen production pathways, the proposed framework achieves a maximum cost saving of 14.2%, thereby establishing a better trade-off between economic efficiency and emission reduction. Additionally, it enhances the robustness and adaptability of planning decisions by proactively managing uncertainties across different time scales. The results also show that the proposed algorithm significantly improves computational efficiency, reducing the computation time by 39.3% for the small-scale case while ensuring stable solutions for larger-scale planning instances.","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"18 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148883982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing EHC studies have focused primarily on cold-start warm-up, while its capability for sustained thermal compensation during prolonged low-load operation, together with its coupled effects on dual-SCR reductant utilization, multi-pollutant emissions, and electrical energy consumption, has not been systematically evaluated. To address these gaps, this study experimentally evaluates an electrically heated catalyst coupled with close-coupled selective catalytic reduction (EHC-ccSCR) system as an active thermal management (ATM) strategy under the World Harmonized Stationary Cycle (WHSC) and Low Load Cycle (LLC), representing steady-state and transient low-temperature operating conditions, respectively. The results show that EHC-assisted ATM provides rapid front-stage thermal activation and promotes downstream thermal propagation, thereby extending the effective urea dosing window and enhancing the coordinated utilization of the dual-SCR system. Under WHSC, 240 s of EHC activation suppressed the initial NOx breakthrough and reduced NOx specific emissions to 19.23 mg/kWh. Under LLC, the dynamic ATM strategy increased downstream SCR urea consumption by 60.4%, indicating a shift from front-stage-dominated NOx conversion to dual-stage SCR coordination, and reduced NOx specific emissions by 95.5% to 53.38 mg/kWh.
