Reconfiguration of Localized Ruthenium Surface via Incorporating Single Platinum Atoms for Favorable Hydrogen Oxidation Catalysis

open access: yesSmall, EarlyView.
The introduction of a Pt single atom changes the Ru surface structure and results in the reconstruction of the active sites for hydrogen and CO oxidation catalysis. With a Pt loading of only 1 wt.%, RuPtSA exhibited superior HOR activity and resistance to impurities compared to commercial Pt catalysts in both acid and alkaline electrolytes.

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
