The first layer consisted of polydopamine (PDA). The rigid building blocks of Na<sub>2</sub>SiO<sub>3</sub> and N-TiO<sub>2</sub> were formed on the SS/PDA surface, resulting in the SS/PDA/Na<sub>2</sub>SiO<sub>3</sub>/N-TiO<sub>2</sub> mesh. Modified meshes were characterized using FESEM/EDX, ATR-FTIR spectroscopy, underwater oil contact angle, and underoil water contact angle methods. The results revealed that the underoil superhydrophobic and underwater superoleophobic coated mesh could selectively remove both heavy and light oils from water for up to twenty repeated cycles, with high separation efficiencies of 94% and 98%, respectively. The modified mesh demonstrated high photocatalytic degradation of methylene blue within 240 min under UV-A illumination. This specially designed membrane offers the benefit of selectively separate heavy and light oils from oil/water mixtures without the need for external stimuli. Furthermore, it exhibits photo-responsive characteristics and can effectively degrade pollutants when exposed to UV-A light. Therefore, the coated mesh can show significant promise for industrial applications.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 6","pages":"4043 - 4054"},"PeriodicalIF":3.0,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

One of the main problems in energy consumption management in the residential sector is that energy reduction is considered without any attention to the thermal comfort level of the residents. Thus, this paper proposes a method for multi-objective optimization using a genetic algorithm based on building simulation to reduce energy consumption as well as increase thermal comfort. The design parameters considered include building orientation, shading parameters, insulation thickness, temperature adjustment points, window-to-wall ratio, and roof insulation thickness. The renewable energy sources considered are photovoltaic panels and wind turbines. There is a significant role to play by climate condition in the optimization of energy use in buildings, leading to the consideration of four different climate zones in Iran to investigate the issue comprehensively. The results show that proper selection of architectural parameters, according to optimization results, and consideration of climatic conditions are vital in reducing energy consumption. The use of energy efficiency methods in different climates of Iran can lead to a reduction of 8.83% to 21.6% in energy consumption. The lowest and highest amount of reduction belongs to the moderate climate (Sari) and the cold climate (Urmia) respectively. The study also highlights the potential for using photovoltaic systems in all climates of Iran and the maximum efficiency of wind turbines in hot and dry climates with the share of providing 40% of energy demand.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 5","pages":"2889 - 2904"},"PeriodicalIF":3.0,"publicationDate":"2024-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

The study focuses on real application of floating power plant, and the information obtained from the analysis is expected to contribute to the design of new or existing systems. Calculations demonstrate wave deformation in severe wind, yielding heterogeneous force distributions. The compressed air flow lines align with areas characterized by high-speed flow, with wind speeds ranging from 30 to 50 m/s. The wave kinetic energy increases due to the wind, resulting in high forces being applied to the surface of the Floating Photovoltaic platform. Turbulence Kinetic Energy exhibits higher values in front of and on the surface of the platform due to the disruption of the airflow. As a result of direct interaction with waves and wind, the front section of the floating system experiences significantly higher loads. The total pressure on the entire surface of the floating platform reaches maximum values of up to 38.677 kN/m<sup>2</sup>. When compared with various analytical methods, it has been observed that the Goda and Morison methods yield closer results. This discrepancy is believed to stem from the omission of wind interactions and platform structure considerations in the analytical methods. Overall, the analysis highlights the importance of considering wind and wave interactions in the design and protection of Floating Photovoltaic systems, and the findings contribute to the advancement of these systems.</p></div>","PeriodicalId":589,"journal":{"name":"International Journal of Environmental Science and Technology","volume":"22 5","pages":"3271 - 3286"},"PeriodicalIF":3.0,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143465906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

Our hypothesis is that impervious surface area is primarily related to the presence of persistent nighttime light in space and time, and that its quantification basically depends on the brightness pattern emitted by the urban surface. Thus, brightness patterns extracted from monthly composites of nighttime light were associated with impervious surface area established through a random forest regression model.
