The results showed that when the calcination temperature was 400 ℃, the calcination time was 4 h, the leaching time was 2.5 h, the ore acid ratio was 1:0.22, and the leaching temperature was 50 ℃, the leaching efficiency of manganese reached 88.62 %, and the concentration of iron in the leachate decreased from 6.88 g/L to 1.95 g/L. When the calcination temperature is raised from 300 ℃ to 400 ℃, the concentration of iron in the leachate decreases, the MnO produced by the continuous decomposition of MnCO₃ in rhodochrosite and the Fe₂O₃ produced by the oxidation of FeS₂ combine to form structurally stable MnFe₂O₄, which plays a dominant role in inhibiting iron leaching. As the calcination temperature continues to rise from 400 ℃ to 500 ℃, the concentration of iron in the leachate increases, attributed to the transformation of MnO into Mn₂O₃ and a small amount of Fe₂O₃ into Fe_1-xS, resulting in a decrease in the source of MnFe₂O₄ formation.

To address these challenges, this paper introduces a HAZOP analysis Completeness Tool (HAZOPCT), which helps to review process designs for enhancing the completeness of HAZOP analysis. Initially, a HAZOP knowledge graph is constructed automatically to integrate multi-source process safety information based on a predefined ontology. Subsequently, HAZOPCT is employed to perform reasoning over the knowledge graph, thereby generating recommended conclusions from similar cases for completing HAZOP analysis. A case study focusing on the sulfur recovery process demonstrates the ability of HAZOPCT to efficiently identify hazards and operability issues that may have been overlooked in original HAZOP analysis tables. Additionally, ablation studies validate the critical role of semantic information and graph attention mechanisms in improving reasoning performance. The generated attention weight network further enhances the interpretability of HAZOPCT, offering insights into the automated reasoning process and contributing to a more transparent and reliable HAZOP analysis.</div></div>","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"197 ","pages":"Article 107025"},"PeriodicalIF":6.9,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143675646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

A well-designed control strategy for hybrid vehicles not only improves operational safety but also ensures that the engine operates along the optimal fuel consumption curve, reducing emissions without compromising safety. However, research on the control of hybrid vehicle platoons mostly neglects the time-delay phenomenon of the powertrain system. This paper proposes a control strategy with time delay compensation for hybrid vehicle platoons aimed at reducing carbon emissions while ensuring safety. First, the optimal velocity of each vehicle in the platoon is obtained through a multi-objective optimization function and used as the target speed for the torque split strategy. Next, the emission reduction strategy aims to make the engine operating point approach the minimum emission curve while simultaneously satisfying the vehicle’s power and velocity requirements. Finally, an optimal torque compensation strategy is introduced to mitigate the influence of the power system’s time-delay phenomenon on control accuracy. Numerical experiments are carried out to verify the effectiveness of the proposed control strategy. The proposed control strategy was tested under the typical urban driving conditions of the New European Driving Cycle, showing a reduction in both cumulative carbon emissions and peak emission levels, while also enhancing driving safety.</div></div>","PeriodicalId":20743,"journal":{"name":"Process Safety and Environmental Protection","volume":"197 ","pages":"Article 107010"},"PeriodicalIF":6.9,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143632188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This study comprehensively compared the impacts of waterborne and foodborne exposure to polystyrene MPs on intestinal accumulation and damage in adult zebrafish (<em>Danio rerio</em>). The findings demonstrated that MPs primarily accumulated in zebrafish intestines in a time-dependent manner, regardless of the exposure route. However, foodborne exposure led to a more rapid accumulation of MPs in the intestines than waterborne exposure. The accumulation and clearance potentials of MPs in zebrafish intestines was similar across both exposure routes. <em>In silico</em> modeling revealed that the accumulated MPs in the zebrafish intestine could closely bind to chymotrypsin, potentially impairing digestive function. Both waterborne and foodborne exposure induced significant intestinal structural damage, cell apoptosis, metabolic dysfunction, and alterations in microbial composition and function in zebrafish. Notably, foodborne exposure resulted in more severe intestinal damage, which may be correlated with the accelerated accumulation of MPs. Additionally, MPs were found to enhance pathogens while inhibiting probiotics in the intestinal flora, which could exacerbate intestinal risks, especially via the foodborne route.

The existing fire extinguishing materials cannot completely solve the problems of LIB cooling, reignition, pollution, and so on. To address this issue, a new gel foam based on konjac gum (KGM) and sodium silicate (WG) was synthesized for extinguishing LIB fires. The gel foam properties, including foaming ability, foam stability, gel time, viscosity, microstructure, element distribution, water retention capacity, thermal stability, cooling ability, and fire extinguishing effect, were explored systematically. The results demonstrate that the gel foam exhibits controllable gel time, excellent adhesion property, and powerful water retention capacity. In addition, the three-dimensional network structure formed by KGM and WG effectively prevents moisture loss between the frameworks, as shown by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy. Meanwhile, the uneven distribution of silicon elements in the skeletal structure enhances the physical strength, structural stability, and thermal stability. Thermogravimetric tests display that decomposition rate of KGM/WG gel foam reaches 0.216 %/℃ and 0.036 %/℃ at 40–110℃ and 110–550℃, respectively, and the final residual content is 68.3 % at 620℃. The cooling performance and fire extinguishing experiments reveal that the KGM/WG gel foam forms an isolation layer on the surface of LIBs with a good anti-rewarming effect, which significantly inhibits the further burning of the flame. The cooling rate of the 18650 lithium-ion battery surface temperature is 3.47℃·s⁻¹, while the cooling rate of the flame temperature is 32.65℃·s⁻¹ without rewarming and reignition phenomena.
