Synergistic extraction of critical metals from the oxalic leachate of spent FCC catalyst
The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study introduces an improved hydrometallurgy process utilizing a synergistic approach to improve metal recovery from secondary sources of critical metals. It provides a more efficient alternative to traditional single‐extractant methods for separating critical metals from spent refinery catalysts.

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 ...

Carbon emission assessment of tunnel infrastructures: From construction to operation
Deep Underground Science and Engineering, EarlyView.This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Deep Underground Science and Engineering, EarlyView.Well XA‐1, completed at a true vertical depth of 11 156 m in the Shawan Sag of the Junggar Basin, is the deepest predominantly near‐vertical well drilled in a sedimentary basin. The figure shows the basin's tectonic framework and well location (a), a structural cross‐section spanning the Shawan Sag and adjacent uplifts (b), and the stratigraphic column
