A commentary on solid lubricants and wear resistant solids for use in extreme environments [PDF]

open access: yes
The need for high temperature tribological coatings and self-lubricating materials in advanced technology is discussed. A qualitative model for the mechanism of solid lubrication is proposed.

The effect of processing and compositional changes on the tribology of PM212 in air [PDF]

open access: yes
The effects of processing and compositional variations on the tribological performance of PM212 were studied. PM212 is a self lubricating powder metallurgy composite, comprised of a wear resistant metal bonded chromium carbide matrix, containing the ...

Japanese irogane alloys and patination – a study of production and application [PDF]

open access: yes, 2009
Japanese metalworkers use a wide range of irogane alloys (shakudo, shibuichi), which are colored with a single patination solution (niiro). This approach allows different alloys to be combined in one piece and patinated, producing a multi-colored piece ...

Mechanoactivated Celite as a Catalyst for C‒H Bond Perfluoroalkylation and Other Radical Reactions

open access: yesAngewandte Chemie International Edition, EarlyView.
Biogenic materials naturally containing trace metals such as Celite or diatomaceous earth promote practical perfluoroalkylation of C─H bonds of (hetero)arenes and a double bond bromination with N‐bromosuccinimide upon mechanoactivation via ball milling. This conceptually broadens the scope of mechanoactivated solids beyond piezoelectric materials. This
