Focusing on the thermodynamic-kinetic coupling mechanisms during CO<sub>2</sub> non-equilibrium condensation, the research reveals how carrier gas properties (hydrogen and methane-dominated natural gas) govern phase transition efficiency under supersonic conditions. Key findings demonstrate that, due to hydrogen's high thermal conductivity and weak intermolecular interactions, hydrogen-rich systems are more prone to forming a large number of small-radius CO<sub>2</sub> liquid droplets in supersonic nozzles compared to natural gas systems. When the inlet temperature is maintained at 270 K, during the process where the molar fraction of CO<sub>2</sub> increased from 0.25 to 0.35, the liquid phase mass fraction of carbon dioxide in the natural gas system increased by 1.44 times, significantly higher than 1.21 times in the hydrogen-rich system. Under a constant CO<sub>2</sub> concentration of 0.3, when the inlet gas temperature decreases from 275 K to 265 K, the growth rate of liquid-phase components in hydrogen-rich systems shows a 20.5 % reduction compared to natural gas systems. Natural gas systems leverage nucleation-density coarsening trade-offs for rapid efficiency gains, while hydrogen systems face diffusion-limited growth constraints.

To bridge this knowledge gap, a microcosm experiment was conducted, focusing on the role of Fe mineralization and comprehensive remediation of As and Cd, which is strongly linked to both biotic and abiotic processes driven by microalgae and their associated bacterial consortia. Results revealed a dual mechanism for metal(loid) immobilization.

Second, the microalgal-bacterial consortia established synergistic interactions that simultaneously mitigated metal(loid) toxicity and enhanced remediation efficiency. Specifically, Fe-oxidizing bacteria generated biogenic Fe minerals with higher As adsorption capacity (As/Fe ratio 0.28 vs. 0.20 in controls), resulting in faster As removal, while sulfate-reducing bacteria facilitated CdS precipitation, collectively enabling &gt;97% Cd removal.

Herding households, as key players in maintaining this balance, must be supported to ensure their well-being is not compromised while managing grassland and livestock. Protecting their welfare is essential for achieving long-term sustainability in these regions. Based on micro-survey data from 402 herding households in the grassland pastoral areas of Ili Prefecture, Xinjiang, this paper employs the Endogenous Switching Regression Model and the Mediation Effect Model to empirically test the impact of grass-livestock balance maintenance behaviors adopted by herding households on family welfare levels. The study reveals the following findings: Grass-livestock balance maintenance behaviors encompass livestock reduction behavior and alternative grazing behavior (such as pen breeding). Across the full sample, alternative grazing behavior significantly enhance the welfare of herding households, whereas livestock reduction behavior exerts a negative impact on family welfare levels. This conclusion is further corroborated through alternative models and the substitution of independent variable. Heterogeneity analysis indicates that for herding households with higher education levels, livestock reduction behavior can significantly boost family welfare levels, which contrasts with the results obtained from the full sample. In contrast, for herding households with lower education and wealth levels, alternative grazing behavior yield a more pronounced welfare-enhancing effect. Mechanism inspection reveals that scaled breeding is a crucial channel through which herding households can enhance their family welfare levels by adopting alternative grazing behavior. Non-livestock employment serves as a vital pathway for herding households to offset the welfare losses incurred from livestock reduction behavior. Therefore, by strengthening technical support for alternative grazing behavior and improving the non-livestock employment market, it is possible to safeguard the welfare of herding households. This, in turn, can encourage them to proactively adopt grass-livestock balance maintenance behaviors, thereby achieving effective governance of grassland ecology.</div></div>","PeriodicalId":349,"journal":{"name":"Journal of Cleaner Production","volume":"520 ","pages":"Article 146062"},"PeriodicalIF":9.7,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144548329","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}

Balancing carbon emission reduction with the need to maintain fish production and improve sustainable management presents a significant challenge. Current research lacks comprehensive analyses of the time-space evolution of carbon emissions in relation to fishery production and their driving mechanisms. This study examined China's marine fishery development over 44 years, focusing on regional carbon emissions and intensity associated with various operation methods over the past 20 years. It also identified the driving mechanisms and contributions of the operational structure to carbon emissions. The findings revealed that while fishery production grew at an annual growth rate of 1.82 %, carbon emissions rose slower (1.26 %). The catch scale is the most critical positive driver of carbon emissions increasing (53.36 %). Spatially, southern China exhibited higher emissions compared to northern regions, with disparities in emissions widening due to operational structures and differences in regional characteristics and reduction potential. The carbon intensity of China's marine fisheries per unit of production has been significantly reduced, contributing 24.70 % of the world's seafood with only 20.32 % of CO<sub>2</sub> over the past ten years. Outlawing energy-intensive capture methods and reducing energy consumption in mariculture have largely contributed to the reduction in emissions (−58.44 % and −37.44 %, respectively). Although intensive production systems in mariculture contribute a lot of seafood at the same emission level, they may also generate externalities such as biodiversity loss, habitat simplification and ecosystem degradation, so the need for an integrated ecosystem-based management approach such as integrated multi-trophic aquaculture should be more emphasized at this time in order to strike a balance between combating climate change and maintaining ecological sustainability.

In conclusion, caution is needed in reducing chemical fertilisers in the short term: while essential for preserving the environment and natural resources, it may involve economic losses, especially where inputs are already used efficiently.

It has been found that WDS configurations with elevated tanks typically require larger BTM solar systems, offering greater flexibility in aligning pump operations with solar energy generation. This in turn leads to higher solar energy utilisation and lower total life cycle costs (TLCC) compared to systems without tanks. In contrast, WDSs without elevated tanks tend to have smaller solar PV systems and may have low efficiency in solar energy utilisation. In addition, it has been found that although a fixed grid feed-in electricity tariff offers additional revenue through selling excess solar energy back to the grid, it has minimal impact on solar PV sizes. In contrast, a dynamic electricity tariff structure leads to smaller BTM solar systems but higher TLCC due to the impact of possible negative electricity prices.
