The world's cultivated land area has expanded by ∼13 % since 1961; however, with the world population doubling since then, we can only rely on half as much land as in 1961 for food production. The rapid exhaustion of natural resources, including land and water, emphasises the necessity for sustainable energy generation. Identifying sustainable energy sources such as biodiesel is critical, particularly when human land use has eradicated half of the planet's forests and agricultural lands are persistently diminishing due to population expansion. Waste cooking oil is a readily available, inexpensive, and widely distributed raw material for biodiesel production. Waste cooking oil is a potential source that can immediately solve the world's needs to generate more useable energy. This review article offers a thorough overview of biodiesel production using conventional methods, intensification processes, and various types of catalysts, along with their advantages and disadvantages. This review delves into optimisation of biodiesel production, including a thorough examination of process parameters such as the methanol/oil molar ratio, catalyst concentration, reaction temperature, reaction time, and stirring speed, and their effects on the biodiesel yield. The kinetics, thermodynamics, and energy consumption of the transesterification reaction, as well as exergy and energy analysis are covered. This article also presents the life cycle analysis and environmental impact assessment. On the whole, the production of biodiesel from waste cooking oil is a cleaner and economical alternative fuel for compression ignition engines.</div></div>","PeriodicalId":418,"journal":{"name":"Renewable and Sustainable Energy Reviews","volume":"217 ","pages":"Article 115769"},"PeriodicalIF":16.3,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143868128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we developed and deployed an automated, low-cost, and time-resolved system for noninvasive monitoring of air toxicity by detecting eight breath-borne biomarkers from rats, including VOCs, CO₂, CO, NO, H₂S, H₂O₂, O₂, and NH₃. Using this system, two large-scale monitoring campaigns were conducted across 13 cities in China during the 2023 winter and 2024 spring continuously on a 24-h-a-day basis. In characterizing overall air pollution health impact, a novel Air Toxic Index (ATI) was developed using the eight breath-borne biomarkers from the rats. Significant differences in diurnal patterns of ATI were observed across 13 cities. Among others, time, city, PM_2.5, and O₃ were identified as the primary influencing factors of ATI, exhibiting complex nonlinear relationships in real-world environments. The unique variation patterns of breath-borne NO and H₂O₂ from rats indicated the time-resolved impacts of ground human activities on weekends and PM components on air toxicity. Histopathologic changes in these deployed rats’ lungs further validated the differential health effects of real-world air pollution from different cities as detected by the rat system. Here, we pioneer a new air pollution health effect monitoring system that realizes the in vivo detection of air toxicity in contrast to the traditional protocol of air sampling, exposure, and offline toxicity analysis steps. The system can be deployed easily to any location with minimal support for real-time monitoring of air pollution health impacts.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"8 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872145","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}

Analysis with a Hamiltonian based on the essential-states model reveals a stepwise transformation from disordered to ordered species, with energy transfer occurring preferentially from aggregates with larger interplanar spacing to more tightly packed aggregates. This study demonstrates how annealing-dependent changes in charge transfer coupling drive energy transfer dynamics in heterogeneous films.

Interfacial structure and energies were computed for ACC and AMC in contact with the (100), (001), and (101) α-quartz surfaces. The simulations showed α-quartz surfaces drew water molecules out of the carbonate nuclei to form a partial hydration layer. The formation of a partial hydration layer and its disruption to the ACC/AMC structure meant the α-quartz–ACC/AMC interfaces were not energetically favored relative to separate α-quartz–water and ACC/AMC–water interfaces and, thus, homogeneous ACC/AMC nucleation was favored over heterogeneous nucleation. The CMD simulations hence provided an atomic-level explanation for a reported nonclassical growth mechanism whereby carbonate minerals grow via homogeneous nucleation and subsequent surface attachment of amorphous intermediates.","PeriodicalId":62,"journal":{"name":"The Journal of Physical Chemistry Letters","volume":"74 1","pages":""},"PeriodicalIF":6.475,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872533","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing dispatch strategies for RIES overlook the varying value of energy storage devices across different time periods, making it difficult to adapt to future energy market development and reduce system operation costs. Therefore, this study constructs a bi-level RIES optimization dispatch model with an energy producer and an energy management center at the upper level, and IESs at the lower level. First, the energy entity dispatch is solved by an improved single-objective black kite algorithm based on a variable predation dynamics strategy (BKAS), while the bi-level dispatch that considers all energy entities is solved by a multi-objective black kite algorithm (MOBKA). Second, a generalized energy pool-driven virtual energy storage framework is proposed to manage energy storage devices without altering the system topology. Additionally, a multi-time-scale synergy carbon-storage game strategy is introduced to balance the economic and environmental benefits of the RIES. Finally, case studies verify the effectiveness and feasibility of the proposed methods and theories. The results show that under the combined effect of the virtual energy storage framework and the carbon-storage game strategy, the economic cost of IESs increases by 1.96 %, carbon emissions decrease by 21.66 %, and the revenue of the energy management center increases by 31.77 %.

In this study, based on a simple one-step pyrolysis method, we designed a Cu single-atom catalyst with high active site exposure and a locally electron-deficient environment (HE Cu₁–N₄) to achieve maximum utilization efficiency in electrocatalytic nitrate reduction (NO₃RR). Using advanced characterization techniques, we confirmed that its unique 3D structure enhances Cu atom exposure and reduces nitrate (NO₃^–) mass transfer resistance. Synchrotron radiation and DFT calculations showed that adjusting the coordination environment induces a local electron-deficient effect in Cu atoms, increasing the electrostatic attraction to NO₃^–. HE Cu₁–N₄ achieved 100% NH₃ selectivity across a wide range of NO₃^– concentrations, with an NH₃ yield (5.09 mg h^–1 mg_cat^–1) nearly 7-fold higher than that of the conventional unmodified Cu single-atom catalyst (Cu₁–N₂, 0.73 mg h^–1 mg_cat^–1). Under pilot-scale conditions, HE Cu₁–N₄ demonstrated strong resistance to interference and excellent stability in complex water systems. A simple modification method enhanced the utilization efficiency of single atoms in single-atom catalysts, significantly improving the catalytic activity of the material. Moreover, this straightforward synthesis strategy holds promise for the large-scale production of single-atom catalysts, paving the way for practical engineering applications.","PeriodicalId":36,"journal":{"name":"环境科学与技术","volume":"16 1","pages":""},"PeriodicalIF":9.028,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872143","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}

Methane oxidation over Pt/Al₂O₃ was chosen as a model reaction to verify the strength of ME-XAS for extracting surface dynamics of Pt nanoparticles of different sizes. ME-XAS spectra revealed that during methane oxidation, only surface Pt atoms were repeatedly oxidized and reduced while the bulk Pt remained mostly metallic. Samples with low Pt loadings were more oxidizable and showed lower methane oxidation activity, in line with metallic Pt being more active for methane dissociation than Pt oxides. This study underscores the potential of ME-XAS to enhance our understanding of surface-bulk dynamics and rationalize catalytic phenomena, offering a pathway to the development of more efficient and selective catalysts.","PeriodicalId":62,"journal":{"name":"The Journal of Physical Chemistry Letters","volume":"42 1","pages":""},"PeriodicalIF":6.475,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
