ChemSusChem, Volume 18, Issue 6, March 15, 2025.Lithium carbonate (Li2CO3) obtained from the black mass of recycled lithium batteries is dissolved in water under controlled conditions to remove lithium fluoride (LiF), which is present at a concentration of 3.08 % by weight. The dissolution is carried out at temperatures below 10 °C, and it has been demonstrated that lower temperatures result in ...

Deep Underground Science and Engineering, EarlyView.The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Deep Underground Science and Engineering, EarlyView.Three sets of strength data were selected, including hydrostatic pressure independent within the brittle region (HPI‐B), hydrostatic pressure dependent within the brittle region (HPD‐B), and hydrostatic pressure dependent within the brittle–ductile region (HPD‐BD). For HPI type, the failure envelope within the deviatoric plane remains constant.
