Structure and optical properties of 2D layered MoS2 crystals implemented with novel friction induced crystal growth

open access: yesAIP Advances, 2018
We used X-ray diffraction, and Raman and photoluminescence (PL) spectroscopies to examine the structure and optical properties of molybdenum disulfide (MoS2) crystals grown by friction at the interface between two materials.

The Effect of Lubricity of Calcium Sulfonate on ZnDTP and MoDTC

open access: yesTribology Letters
AbstractReduction of friction and wear by lubrication is necessary to improve the efficiency and prolong the lifespan of industrial machinery. However, several aspects regarding the lubrication effects in additive-combined oil are still unresolved.

XPS study of the influence of temperature on ZnDTP tribofilm composition [PDF]

open access: yes, 2018
Antiwear additives, such as zinc dialkyldithiophosphate (ZnDTP), find application in many different industrial sectors. Although it is understood that certain ZnDTP concentrations need to be used to achieve an effective antiwear performance, there has ...

Low and zero SAPS antiwear additives for engine oils [PDF]

open access: yes, 2013
Almost all modern engine lubricants use the additive zinc dialkyldithiophosphate (ZDDP) to provide antiwear and extreme pressure protection. However existing and proposed emissions regulations include constraints in the concentration of ZDDP or other ...

Effect of nanoparticles as lubricant additives on friction and wear behavior of tetrahedral amorphous carbon (ta-C) coating [PDF]

open access: yesJurnal Tribologi, 2018
As diamond like carbon (DLC) coating becomes increasingly popular in providing low friction and wear under lubricated conditions, the effect of various oil additives on tribological behavior of DLC coating is drawing more attention. Various oil additives,
