Shear activation of ZDDP reaction films in the presence and absence of nanodiamonds

Applied Surface Science Advances, 2022
We explore the impact of shear stress and nanodiamond (ND) additives on the formation temperatures of thermal- and tribo- reaction films of steel samples immersed in basestock oils containing zinc dialkyl dithio-phosphate (ZDDP) additives.

Detailed chemical analysis of a fully formulated oil using dielectric barrier discharge ionisation-mass spectrometry. [PDF]

Rapid Commun Mass Spectrom, 2022
Rationale Fully formulated oils (FFOs) are integral to automotive lubrication; however, detailed compositional analysis is challenging due to high levels of chemical complexity. In particular, existing mass spectrometric approaches often target particular FFO components, leading to poor analytical coverage of the overall formulation, with increased ...

Chemical analysis of additives included in fully formulated oils using high-performance liquid chromatography-tandem mass spectrometry. [PDF]

Rapid Commun Mass Spectrom
Rationale Fully formulated oils (FFOs) are chemically complex petrochemical products composed of base oil and additive mixtures that are employed in automotive engines to provide lubrication. In particular, the additive portion of FFOs is often precisely controlled to tailor the resultant formulation to a specific role.
