Process for the recycling of alkaline and zinc–carbon spent batteries
TL;DR: In this article, a recycling process for the recovery of zinc and manganese from spent alkaline and zinc-carbon batteries is proposed, and a technical-economic assessment is carried out for a recycling plant with a feed capacity of 5000 t/y −1 of only battery batteries.

Shear-induced graphitization of carbonaceous materials during seismic fault motion: Experiments and possible implications for fault mechanics
TL;DR: In this article, the authors performed friction experiments on amorphous carbon and graphite to investigate how graphite forms in association with fault motion and how these carbonaceous minerals affect frictional properties of faults.

Comparison of the oxidation rate and degree of graphitization of selected IG and NBG nuclear graphite grades
Se-Hwan Chi,Gen-Chan Kim +1 more
TL;DR: In this paper, the degree of graphitization (DOG) was determined for some selected nuclear graphite grades (i.e., IG-110, IG-430, NBG-18, N BG-25) and compared in view of their filler coke type (either pitch or petroleum coke) and the physical property of the grades.

The effect of microstructure on air oxidation resistance of nuclear graphite
TL;DR: The relationship between graphite microstructure and its oxidation resistance was investigated in this article, where three grades of graphite with different structures were compared using a standard thermogravimetric method and structural differences were ascribed to structural differences between the three graphite grades, in particular the grain size and shape of the graphite filler.
