On the Transient Decomposition and Reaction Kinetics of Zinc Dialkyldithiophosphate [PDF]

ACS Applied Materials & Interfaces, 2018
Despite the ubiquitous use of the zinc dialkyldithiophosphate (ZDDP) as an antiwear additive, no complete information is yet available on its exact decomposition reactions and kinetics to form triboreactive protective films on contacting surfaces.

Interfacial friction enabling ≤ 20 μm thin free-standing lithium strips for lithium metal batteries [PDF]

Nature Communications, 2023
A practical high-specific-energy Li metal battery requires thin (≤20 μm) and free-standing Li metal anodes, but the low melting point and strong diffusion creep of lithium metal impede their scalable processing towards thin-thickness and free-standing ...

Synergistic Enhancement of the Lubrication Performance of Zinc Dialkyldithiophosphate by Coexistence with Ionic Liquid

Tribology Online, 2021
Ionic liquids (ILs) are being considered as novel lubricant additives to improve the friction and anti-wear characteristics of sliding surfaces. Because ILs consist of only cations and anions, their physical and chemical properties can be easily tailored

Green Alternatives to Zinc Dialkyldithiophosphates: Vanadium Oxide-Based Additives

ACS Applied Engineering Materials, 2023
A functionalized vanadyl(IV) acetylacetonate (acac) complex has been found to be a superior and highly effective antiwear agent, affording remarkable wear protection, compared to the current industry standard, zinc dialkyldithiophosphates (ZDDPs). Analysis of vanadium speciation and the depth profile of the active tribofilms by a combination of X-ray ...
