Effect of tangential traction and roughness on crack initiation/propagation during rolling contact [PDF]

open access: yes
Rolling fatigue tests of 0.45 percent carbon steel rollers were carried out using a four roller type rolling contact fatigue tester. Tangential traction and surface roughness of the harder mating rollers were varied and their effect was studied.

Nature‐Positive Materials Engineering: Carbon Electrodes from Satoyama Biomass

open access: yesThe Chemical Record, EarlyView.
Nature‐positive materials engineering can link satoyama forest stewardship with the design of carbon electrodes for batteries, supercapacitors, and electrocatalysis. By turning underused firewood and charcoal resources into functional carbons, this approach reduces mining footprints while supporting biodiversity, landscape resilience, and regional ...

High‐Pressure Synthesis and Chemical Bonding of Mg3BiN

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The anti‐perovskite Mg3BiN is obtained by high‐pressure high‐temperature reaction of Mg–Bi mixture with boron nitride serving as crucible material. The compound is electron precise with essentially ionic bonding, and DOS calculations indicate semiconducting behavior.
