'Artificial leaf' successfully produces clean gas

A widely-used gas that is currently produced from fossil fuels can instead be made by an 'artificial leaf' that uses only sunlight, carbon dioxide and water, and which could eventually be used to develop a sustainable liquid ...

Can sodium-ion batteries replace trusty lithium-ion ones?

Sodium-ion batteries are a potential replacement for lithium batteries, but the anodes—positively charged electrodes—that work well for lithium-ion batteries don't provide the same level of performance for sodium-ion ...

Software tool could help architects design efficient buildings

Typically, when architects or engineers design a new building, it's only at the end of the process—if ever—that a life cycle analysis of the building's environmental impact is carried out. And by then, it may be too late ...
