Synergistic Effects of Drought and Fire Intensity Drive Carbon Source Shifts in Chinese Forests

Forest fires profoundly affect ecosystem carbon sink functions through direct carbon emissions and ecological process disturbances. However, the mechanisms by which fire carbon emissions (FCE) influence net ecosystem productivity (NEP) remain poorly understood. Here, we analyzed...

Delocalized Electronic Buffering at Pd/High-Entropy Oxide Interfaces Enables Water-Tolerant Methane Oxidation

Abstract Developing Pd-based catalysts for methane oxidation that combine low-temperature activity with strong water tolerance remains a major challenge for emission control applications. Herein, we introduce a high-entropy architecture into Co3O4-based spinel supports to regulat...

Interfacial Tensions of Extended Surfactant Solutions: Effect of Alkane Chain Length on the Size of Propylene Oxide Groups

Abstract To explore the mechanism for lowering interfacial tension by extended surfactants, the interfacial tension values of extended surfactants (S–C13POnS and G-C16POnS) were measured using the spinning drop method. Additionally, molecular dynamics simulation was employed to v...

Low-Carbon Valorization of Waste PE Mulch Film: A Carbon Footprint Comparative Analysis of Typical End-of-Life Treatment Pathways

Widespread polyethylene (PE) mulch film application has caused severe farmland plastic pollution and greenhouse gas emissions. To identify low-carbon end-of-life pathways for waste agricultural mulch film, this study established a full life-cycle carbon footprint model comparing...

Analysis of the Composition and Thermogravimetric Kinetics of Vacuum Residue from Karamay

Vacuum residue (VR) is one of the more difficult heavy fractions to process in petroleum refining, and the development of clean utilization technologies for vacuum residue has become a major research focus in the petrochemical industry. This paper discusses the compositional and...
