On the mechanism of ZDDP antiwear film formation [PDF]

open access: yes, 2016
Zinc dialkyldithiophosphate additives are used to control wear and inhibit oxidation in almost all engine oils as well as many other types of lubricant. They limit wear primarily by forming a thick, protective, phosphate glass-based tribofilm on rubbing ...

Comprehensive structural model of the mechanochemical cycle of a mitotic motor highlights molecular adaptations in the kinesin family [PDF]

open access: yes, 2014
Kinesins are responsible for a wide variety of microtubule-based, ATP-dependent functions. Their motor domain drives these activities but the molecular adaptations that specify these diverse and essential cellular activities are poorly understood.

Mechanochemistry of supramolecules [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2019
The urge to use alternative energy sources has gained significant attention in the eye of chemists in recent years. Solution-based traditional syntheses are extremely useful, although they are often associated with certain disadvantages like generation of waste as by-products, use of large quantities of solvents which causes environmental hazard, etc ...

TG, FT-IR and NMR characterization of n-C16H34 contaminated alumina and silica after mechanochemical treatment [PDF]

open access: yes, 2008
This paper deals with the application of mechanochemistry to model systems composed of alumina or silica artificially contaminated with n-C16H34. The mechanochemical treatment was carried out by means of a ring mill for times ranging from 10 to 40 h ...
