Researchers made cement-based structural electrodes partly from industrial solid waste and added either graphene nanoplatelets or carbon nanotubes. Both additives greatly increased energy-storage capacity, but they also reduced compressive strength, creating a tradeoff between storing energy and supporting loads.
Researchers developed an AI-powered pipeline that extracts information about concrete materials from scientific papers and organizes it into a database. Applied to a corpus screened from more than 27,000 publications, the system produced nearly 9,000 records for an open database on blended cement concrete.
A climate-model study finds that permafrost can continue thawing and releasing carbon for decades after warming begins to decline. The delay in recovery was larger when peak global warming exceeded 2 °C, although the results come from idealized experiments with one Earth system model.
