Study of the Performance and Smoke Density When Gasoline–Diesel Blends Are Used as Fuel of a Diesel Engine

open access: yesJournal of Engineering
The world is currently facing a serious environmental crisis, partly driven by the pollutant emissions from diesel engines. Although these engines are known for their efficiency, their emission levels are highly dependent on fuel quality.

Load factor evaluation and emissions calculation for the cultivator under real working conditions

open access: yesJournal of Agriculture and Food Research
Currently, emission management for agricultural machinery in South Korea only targets diesel engines, leading to insufficient management of gasoline engines.

Selective Production of Methanol via Bidentate Coordination of an Intermediate on the Dual‐Atom Electro‐Catalyst

open access: yesSmall Methods, EarlyView.
This study utilizes density functional theory (DFT) and constrained molecular dynamics (cMD) to investigate the free energy landscape of the electrochemical CO2 reduction reaction at a liquid–solid interface. The research highlights a dual‐atom catalyst—specifically a Cu─Sn pair anchored in a nitrogen‐doped carbon framework—that facilitates the ...

Advancements and Challenges in Second‐ and Third‐Generation Biofuels: A Comparative Analysis of Lignocellulosic and Algal Feedstocks

open access: yesSafety Science and Technology, EarlyView.
ABSTRACT Advanced biofuels derived from nonfood biomass are increasingly recognized as strategic components of low‐carbon energy systems, particularly for sectors where direct electrification remains difficult. Second‐generation biofuels from lignocellulosic residues and third‐generation biofuels from algal and aquatic biomass offer complementary ...

Micronuclei and Other Nuclear Abnormalities in Patella Limpet as Biomarkers of Cytogenotoxicity in Recreational Port Waters

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Over the past decades, the growth in human population and economic activities has led to an increase in maritime traffic. This rise puts additional pressure on marine environments, vessel fuel spills being considered to have a major impact on the ecosystem.

Hevea brasiliensis seeds: A novel sustainable feedstock for ethanol production

open access: yesVietnam Journal of Chemistry, EarlyView.
Abstract The rubber tree (Hevea brasiliensis) is cultivated on a large scale mainly for the extraction of latex in Brazil and Southeast Asia, also generating large quantities of seeds. These seeds currently do not have large‐scale applications and may thus be considered as a residue.

Using Harvest Data to Assess Factors Influencing Regional Population Declines of Muskrats (Ondatra zibethicus) 利用捕获数据评估影响麝鼠 (Ondatra zibethicus) 区域种群数量下降的相关因素

open access: yesWildlife Letters, EarlyView.
Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Application of Intelligent Systems in CO2 Management: State of the Art and Future Prospects

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Machine learning (ML) integration is becoming increasingly popular in advancing the 4th industrial revolution, known as Industry 4.0. This review paper examines ML applications in CO2 management stages: emission, capture, and conversion. ML models, including multiple linear regression (MLR), multiple nonlinear regression (MNLR), and artificial

Engineering Apprenticeships: Youth Transitions, Industrial Capital and the Role of Working‐Class Households

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT Using biographical methods, the study explores the lives of 34 young people undertaking engineering apprenticeships in Teesside, Northeast England. It examines why working‐class youth in a deindustrialised region might be attracted to engineering, how they might secure apprenticeship, and the invaluable role households play in orchestrating ...
