A memory of Paleozoic to Quaternary Greenhouse climates recorded in Southern African regolith

Abstract In this article, we explore the potential of iron-rich duricrust regoliths from old erosional anorogenic surfaces to record clues of the long-term continental paleoclimatic evolution. We coupled geochemical, mineralogical and geochronological analyses on iron oxides and...

Technology qualification plan for very large wind turbine blades

As wind turbines scale beyond 15 MW and blades exceed 100 m in length, ensuring structural integrity and operational reliability becomes increasingly complex. Accelerated development cycles and intensifying global market competition, driven by the emergence of new turbine manufac...

New mechanistic insights into the widely used LiPO2F2 additive enabled by ultra-high-resolution FTICR-MS

Understanding how electrolyte additives influence the formation and evolution of the solid electrolyte interphase (SEI) is essential for improving the durability of lithium‑ion batteries. In this work, we investigate the role of lithium difluorophosphate (LiPO2F2, LiDFP) in 1 M L...
