Weiwei Tang,Zhe Zhang,Yufeng Li +2 more
TL;DR: In this paper, a review of the progress in the research and development of CQDs-based lubricant additives by introducing lots of successful applications of carbon quantum dots-based additives is presented, along with some discussion on challenges and perspectives in this significant and promising field.
Journal ArticleDOI
Remaining useful life prediction of lubricating oil with dynamic principal component analysis and proportional hazards model
TL;DR: In this article, the authors describe how lube oil degrades with serving time and causes severe wear afterwards, which is a sign that the lube contains a lot of tribological information of the machine and plays an important role in machine health.
Journal ArticleDOI
FTIR analysis and monitoring of used synthetic oils operated under similar driving conditions
TL;DR: In this article, the Fourier transform infrared spectroscopy (FTIR) spectrum of an engine oil sample was evaluated with the Thermo Nicolett IS5 and the results may facilitate decision-making regarding the service life of engine oils.
Journal ArticleDOI
Examining the role of hexagonal boron nitride nanoparticles as an additive in the lubricating oil and studying its application
TL;DR: In this article, the additive present in the conventional lubricant is inadequate to reduce the friction and wear of many mechanical systems, and the additives present in conventional lubricants are not enough to reduce friction.

Physicochemical Characterization of the Synthetic Lubricating Oils Degradation under the Effect of Vehicle Engine Operation
TL;DR: The degradation analysis of synthetic lubricating oils during operation of the vehicle engine was undertaken according to the number of kilometers covered, using the evaluation of viscosity, basicity, pour point, flash point, formation of heavy metals from the engine abrasion phenomena, that will detect by inductively coupled plasma optical emission spectrometry (ICP/OES), and the differentiation of the chemical composition of virgin and degraded lubricating oil using gas chromatography associated with mass spectrometers (GC/MS).
