Overcoming limitations of hydrothermal carbonization of biomass: secondary char extraction enhances solid fuel and soil amendment applications
Hydrothermal carbonization (HTC) thermochemically upcycles agro-industrial waste into a two-phase hydrochar (HC) consisting of primary char (PC) and amorphous secondary char (SC). SC limits the use of HC; its furan groups are phytotoxic, and the SC is thermally reactive, making it unsuitable for…

Suppressing Sr segregation in SOFC cathodes via infiltration-driven cationic surface enrichment
Sr segregation is one of the critical degradation issues in perovskite cathode for solid oxide fuel cells (SOFCs), leading to the formation of insulating secondary phases that block active sites and accelerate performance decay. Conventional mitigation strategies rely on A-site deficiency to reduce…

Rapid prediction of electrolyte-based cell failure in retired Li-ion electric vehicle pouch cells
Lithium-ion batteries (LIBs) exhibit sudden non-linear degradation (known as the cell knee point) in operating use, but a quick, simple, and industrially applicable method of predicting knee point failure remains elusive. Addressing this gap, we show for the first time that the Warburg coefficient…
