Integrity analysis of polyamide 12 applied in oil pipelines

Journal of Thermal Analysis and Calorimetry
Abstract Pipes of polyamide were installed in oil fields and, after one year of operation, were removed and analyzes were carried out to assess any degradation and study its use in oil pipelines as corrosion mitigation. The outer layers of all field samples and the unaged sample did not show, in the DSC, any primary peak close to the melting ...

A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries

Advanced Energy Materials, EarlyView.
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li
