Comparative Study of Plant‐Based Antioxidants on the Stability of Soybean and Beef Tallow Biodiesels

Energy Science &Engineering, Volume 13, Issue 4, Page 1706-1719, April 2025.
ABSTRACT Biodiesel is a renewable alternative fuel, but its oxidative instability reduces quality and performance over time. This study explicitly aimed to investigate the efficacy of natural antioxidants—acerola, soursop, mango, and pitanga leaves—and compare their performance to the synthetic antioxidant butylated hydroxytoluene (BHT) in enhancing ...

Application of Tire Pyrolysis Oil as an Alternative Fuel for Internal Combustion Engines—A Literature Review

Journal of Combustion, Volume 2025, Issue 1, 2025.
Tire pyrolysis oil (TPO) has been recently used as an alternative to conventional fuels for internal combustion (IC) engines in order to satisfy some environmental and economic concerns. The main focus of this review is to shed light on the importance of TPO as an alternative fuel for IC engines. This paper systematically describes the TPO productions,

European long‐term care marketisation: A political economy framework

Social Policy &Administration, Volume 58, Issue 7, Page 1059-1074, December 2024.
Abstract The study of European long‐term care (LTC) marketisation is dominated by institutional and ideational perspectives. In contrast, political economic theoretical frameworks have received little attention. This is paradoxical, because marketisation is an inherently political economic phenomenon.

The mechanism and effect factors of the combustion cycle‐to‐cycle variations in the spark ignition engine

Energy Science &Engineering, Volume 12, Issue 10, Page 4773-4787, October 2024.
The authors comprehensively reviewed the fundamental reasons and mechanism of cycle‐to‐cycle variations (CCVs) of a spark ignition (SI) engine. In addition, the characteristic parameters and characterization methods of the CCV, the laws and influencing factors of the CCV, and the numerical simulation methods of the CCV were introduced in detail to ...
