Nanofluids have gained significant popularity in the field of sustainable and renewable energy systems. The heat transfer capacity working fluid has a huge impact on efficiency system. addition small amount high thermal conductivity solid nanoparticles to base improves transfer. Even though large research data is available literature, some results are contradictory. Many influencing factors, as well nonlinearity refutations, make nanofluid highly challenging obstruct its potentially valuable uses. On other hand, data-driven machine learning techniques would be very useful for forecasting thermophysical features rate, identifying most influential assessing efficiencies different primary aim this review study look at applications employed nanofluid-based system, reveal new developments research. A variety modern algorithms studies systems examined, along with their advantages disadvantages. Artificial neural networks-based model prediction using contemporary commercial software simple develop popular. prognostic may further improved by combining marine predator algorithm, genetic swarm intelligence optimization, intelligent optimization approaches. In well-known networks fuzzy- gene-based techniques, newer ensemble such Boosted regression K-means, K-nearest neighbor (KNN), CatBoost, XGBoost gaining due architectures adaptabilities diverse types. regularly used fuzzy-based mostly black-box methods, user having little or no understanding how they function. This reason concern, ethical artificial required.

Hydrogen Production by Water Splitting with Support of Metal and Carbon-Based Photocatalysts

ACS Sustainable Chemistry & Engineering, Год журнала: 2023, Номер 11(4), С. 1221 - 1252

Опубликована: Янв. 18, 2023

Hydrogen energy is environmental-friendly and considered an attractive alternative to fossil fuels. Among the feasible technologies for hydrogen generation, photocatalysis-derived from water splitting be optimal solution meeting long-term sustainability increased demands. In this context, various photocatalytic genres are proposed, with metal carbon-supported photocatalysts demonstrating greater comprehensiveness potential addressing solar-driven production water. Several important aspects of aforementioned reviewed in present work effort provide pertinent researchers new horizons more advanced performance. The review initiated by introducing primary principles photocatalysis, as well prerequisites generation focus then moves metal-based photocatalysts, where features these materials summarized. Related limitations also discussed, along proposed strategies that could potentially mitigate them. Similar systematic summaries made knowledge on carbon-based photocatalysts. concludes a discussion future research directions light bottlenecks currently encountered. With proper development, produce clean water, thereby fueling global development without causing environmental harm.

Blue carbon and the role of mangroves in carbon sequestration: Its mechanisms, estimation, human impacts and conservation strategies for economic incentives

Journal of Sea Research, Год журнала: 2024, Номер 199, С. 102504 - 102504

Опубликована: Май 10, 2024

Mangroves, tidal marshes, and seagrasses have been recognized as blue carbon coastal ecosystems they accommodate large stocks, enable long-term storage, the capacity to control greenhouse gas emissions possess potential reduce rise in atmospheric CO2 levels. In tropical subtropical intertidal zones, mangroves show significant productivity rapid deposition rates. Mangroves play an important role capturing, transforming, storing atmosphere into sediments for a long time displacing organic from zone offshores ocean. also help preventing storms, hurricanes, erosion, waves. Recently, threatened natural anthropogenic activities such urbanization, pollution, aquaculture tourism. They are expected hamper their essential services, defense, breeding grounds aquatic organisms' seafood supply, etc. Despite importance of mangrove forests sequestration well numerous goods services offer humans, including wood non-wood forest products, food, fisheries, medicines, eco-tourism, recreation. These deteriorating at alarming rates, necessitating immediate intervention. Thus, protection, restoration conservation this ecosystem gaining considerable attention researchers across globe. This paper provides information on different adaptations, mechanisms, roles ecosystem, estimation, influencing factors, threats, strategies invaluable habitat.

Leveraging the trend analysis for modeling of the greenhouse gas emissions associated with coal combustion

Environmental Science and Pollution Research, Год журнала: 2024, Номер 31(39), С. 52448 - 52472

Опубликована: Авг. 16, 2024

In this paper, it is aimed, for the first time, at deriving simple models, leveraging trend analysis in order to estimate future greenhouse gas emissions associated with coal combustion. Due expectations of becoming center global economic development future, BRICS-T (Brazil, Russian Federation, India, China, South Africa, and Turkiye) countries are adopted as cases study. Following models' derivation, their statistical validations estimating accuracies also tested through various metrics. addition, combustion estimated by derived models. The results demonstrate that models can be successfully used a tool combustions accuracy ranges from least 90% almost 98%. Moreover, show total amount relevant world will increase 14 BtCO
