A new study shows that systems designed to capture methane from cow manure, called dairy digesters, are highly effective. But on the rare occasions they fail, the leaks are large enough to offset their climate benefits.

Researchers at The University of Manchester have created a groundbreaking physics‑informed machine‑learning model that can run molecular simulations for unprecedented lengths of time, even at temperatures as high as 1000 Kelvin.

A research team has developed an innovative approach to create advanced carbon materials for potassium-ion energy storage, presenting a significant stride towards more sustainable and efficient battery technologies. Utilizing a "twice-cooking" strategy, the scientists engineered an edge-nitrogen-rich lignin-derived carbon nanosheet framework (EN-LCNF), which dramatically improves the performance of potassium-ion hybrid capacitors (PIHCs). This development addresses key limitations in current amorphous carbon anodes, which often suffer from insufficient storage sites and sluggish ion diffusion kinetics, hindering their application in large-scale energy systems. The work represents a resourceful utilization of lignin, an abundant and low-cost biomass, offering a compelling alternative to conventional lithium-based energy solutions.
