Effect of ZrB$_2$ additions on the thermal stability of polycrystalline diamond [PDF]
arXiv, 2023 This study investigates the effect of ZrB$_2$ additions on the microstructure, thermal stability, and thermo-mechanical wear behaviour of polycrystalline diamond. Following high-pressure high-temperature (HPHT) sintering, the ZrB$_2$-PCD material showed a full conversion of the binder phase to cobalt-boride (Co2B and Co$_{23}$B$_6$) phases.

Of fiery sparks & glittering spots: Melting-resolidification and spherical particle formation in abrasion [PDF]
, 2022 The curious occurrence of perfectly spherical particles when a steel substrate is slid against a hard abrasive was first observed and documented by Robert Hooke in the 17$^{th}$ century. Similar particles have subsequently been observed in numerous other abrasion-type processes, ranging from grinding of steels to sliding rock faults.

AIChE Journal, Volume 69, Issue 1, January 2023., 2023 Abstract A possibility to carry out sorption‐enhanced gasification (SEG) is represented by its integration with the calcium looping concept in dual interconnected fluidized beds (DIFB). This article is focused on the sorbent CO2 uptake performance and attrition/fragmentation tendency when operating conditions simulating those of a DIFB‐SEG process are ...
