Effects of hybrid metal oxide nanoparticles on the tribological and emission attributes of algae‐derived biofuel in compression ignition engines

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The growing demand for sustainable fuels has accelerated the development of algae‐derived biodiesel for compression‐ignition engines. In this study, Chlorella vulgaris methyl ester (AME) exhibited physicochemical properties comparable to diesel and satisfied ASTM D6751 fuel quality requirements, making it suitable for blending.

Investigation of Tire‑Tread Rubber Hysteretic Behaviour on Aggregates Through Experiments and Modelling

Journal of Tribology, EarlyView.
ABSTRACT Friction between tire rubber and pavement is governed by the interplay of hysteresis and adhesion yet their individual contributions remain difficult to quantify. This study addresses the long‐standing challenge by using reciprocating sliding tests by means of a tribometer and viscoelastic finite element modelling (FEM) to investigate rubber ...
