Herein, we present a process for recovering used locomotive engine oil using ultrasound-
assisted extraction and sustainable organic solvents. We evaluated the quality of the oil …

The rheological and tribological properties of 0.5%, 1.0%, 1.5% and 2% CuO nanoparticles
by weight blended in engine oil were studied. Surfactants were used to ensure maximum …

Lubricant oil is commonly used to reduce friction and prevent corrosion. It also protects the
metallic components of the machine from wear and tear due to continuous operation …

The rheological and tribological properties of dates (Balanites Aegyptiaca) oil as bio-
lubricants blended with graphene oxide nanoparticles (GNP) have been studied. SDS …

In this study, the rheological characteristics of the waste and pure lube oils were investigated
experimentally. Studying these characteristics are useful for understanding the behavior of …

Most QCM-based devices devoted to PM measurement use substrates of various kinds to
collect and retain particles. The novelty of this work is the possibility to use an integrated …

Abstract Analysis of used lubricating oils is one of the tools that enable the diagnosis of the
operation condition of the engine, and it is a widespread predictive maintenance practice in …

Alkylnaphthalenes as one of the important lubricating base oils were generally produced by
alkylation of naphthalene with olefins, halides, or alcohols. Herein, a totally different …

Hydraulic oil degrades expediently during operating at elevated temperatures, and due to oil
degradation, malfunction of all hydraulic components starts that hampers the hydraulic …

Lubricating oil is the combination of base oil and additives which undergo several chemical
changes due to oxidation reactions occurring at higher temperatures and pressure. The …
