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.

Qingdao, China – The pervasive presence of industrial dyes and toxic heavy metals in global water systems poses an urgent environmental challenge. Researchers have developed a sophisticated and reusable adsorbent material, derived from the abundant marine green tide species Enteromorpha prolifera, that demonstrates remarkable efficacy in removing these complex contaminants from water. This innovative solution transforms an ecological nuisance into a powerful tool for environmental remediation, offering a promising pathway for sustainable wastewater treatment.

In an era demanding sustainable solutions for water and energy scarcity, constructed wetland-microbial fuel cell (CW-MFC) systems present a compelling integrated technology. These systems combine the natural purification capabilities of wetlands with the bioelectrochemical energy generation of microbial fuel cells, offering a dual benefit of wastewater treatment and bioelectricity production. A recent comprehensive review, published in Carbon Research, synthesizes the advancements in electrode strategies crucial for maximizing the performance of CW-MFCs, providing a vital roadmap for future development and broader application.
