A new copper-magnesium-iron catalyst transforms CO2 into CO at low temperatures with record-breaking efficiency and stability. The discovery paves the way for affordable, scalable production of carbon ...

Greenhouse gas concentrations increased by a record amount in 2024 as more carbon dioxide, methane and nitrous oxide became locked in Earth's atmosphere, a World Meteorological Organization report ...

At present cerium oxide nanoparticles (CeO2 NP) have numerous applications ranging from industry to the household, leading to its wide distribution namely in the aquatic environment. The hereby study ...

Concrete has been around for millennia, but Terra CO2 thinks it has a better way to make the ubiquitous building material, and investors appear to agree. The Golden, Colorado-based startup recently ...

Scientists have developed a material with photosynthetic bacteria that convert carbon dioxide into a mineral skeleton. The material hardens over time, so it could be used for buildings, they say. When ...
