The mixed surfactant pairs, i.e., NaLS+Brij-35 and NaLS+Tween-80, with photosensitizer methylene blue and reductant D-xylose have been used for PG cells. The resulting photoelectrochemical process in photogalvanics leads to energy conversion for sustainable development in the field of solar energy. The electrical outcomes, i.e., V_OC, SPP, SPC, SP, and SCE, were studied for a sunlight-induced PG cell for photocatalytic conversion. The observed V_OC, SPP, SPC, SP, and SCE with NaLS+Tween-80 surfactant is of the order of 1120 mV, 867 mV 238.00 µA, 206.34 µW, and 1.3012 %, respectively.

In this regard, electrocoagulation has emerged as a leading technology for chromium removal from tannery wastewater. In this study, a continuous electrocoagulation column was applied for the removal of chromium ions from tannery wastewater collected from local industry. The effect of current density, pH, and effluent chromium concentration were studied for the removal of chromium ions.

From 1880–1980, the global average temperature increased by 1°C per century. Land Surface Temperature (LST) is a crucial climatic variable for analyzing the interaction between the Earth's surface and the atmosphere. Java Island has the highest population and is more urbanized than other islands in Indonesia. From January 2001 to January 2020, LST daytime data were downloaded from NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS) Land Products Global Subsetting and Visualization Tool. This study aims to investigate the LST seasonal patterns and trends of Bali and Java islands. The appropriate distance between sub-regions was also observed, with 105 pixels and 52.5 pixels producing two and six super-regions, respectively. It was found that seasonal patterns could be represented with pixel distances of 105 and 52.5, using eight knots of cubic splines. From 2001–2020, the lowest LST was recorded in January, while the highest was in September. The highest average daily LST, 38.32 °C, was found in Cikande, Serang, and Banten, likely due to industrial activity. This study also analyzed LST fluctuations using seven knots of the cubic spline. It was found that the average daily LST decreased by −0.113 °C per decade in Java and Bali. The western super-regions of Java showed significant LST increases, while the eastern super-regions showed slight decreases. For the 52.5-pixel distance, there was no substantial variation in average LST, though Jakarta and Banten showed significant increases. The 105-pixel distance is useful for examining LST variations on small islands like Java, while the 52.5-pixel distance can detect deeper variations in smaller super-regions. This study also noted that monsoon season and precipitation impact LST decline, and suggested that further research is needed to validate these findings. Additional variables like NDVI, land elevation, and land cover should be considered for more accurate estimations, especially on larger islands or continents farther from the equator.</div></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"6 ","pages":"Article 100096"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143163058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite being a major greenhouse gas, CO₂ holds significant potential as a sustainable feedstock for chemical production. It can serve as a solvent, a preservative, a raw material for producing fuels, carbonates, polymers, and chemicals, and as a recovery agent for processes such as enhanced coal bed methane and oil recovery. This review highlights significant progress made in CO₂ capture and its integration into various industrial applications. While technologies such as adsorption, absorption, membrane separation, and cryogenics have shown promise, challenges related to cost, scalability, and the efficiency of capture and utilization continue to pose significant barriers to widespread adoption. Innovative strategies, including integrated carbon capture and conversion (ICCC) and integrated carbon capture and utilization (ICCU), present promising pathways to reduce costs by combining capture and utilization processes within a single facility. Additionally, catalytic processes and biological systems, such as microalgae and microbial strains (e.g., acetogens), are paving the way for sustainable CO₂ conversion into high-value products. Successful large-scale deployment of these technologies will require sustained interdisciplinary collaboration, robust policy frameworks, and increased investment in research and development. Prioritizing sustainable energy development and management offers the potential to significantly reduce anthropogenic CO₂ emissions while creating useful products.

As a result, the behavior of the adsorbent under controlled conditions was successfully modeled, and relevant interactions between the material and Ca²⁺ ions were identified under simulated conditions.

In simulated treated wastewater, the adsorption of the nutrient was enhanced in the presence of Ca²⁺; however, the formation of insoluble Ca/P deposits on the adsorbent surface significantly changed the adsorption dynamics and disturbed the recovery of Phosphorus using the usual alkaline desorption method.
