Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

Unburned Carbon in Coal Fly Ash: Exploring Its Potential for Electrochemical Energy Storage in Supercapacitors

Advanced Energy and Sustainability Research, Volume 7, Issue 4, April 2026.
The graphical abstract illustrates a circular waste to value pathway in which coal fly ash is upgraded by isolating unburned carbon and converting it into functional carbon materials. Through carbonization and activation, UC‐derived carbon is transformed into high surface area electrodes for supercapacitors, supporting sustainable energy storage and ...

Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

Archaeology in Oceania, Volume 61, Issue 1, Page 177-198, April 2026.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.
