Harvesting water from air with less energy

Getting clean water to communities in parched areas of the planet remains an ongoing challenge. Recent developments that harvest water from air have been proposed as a solution. However, the technology to do so consumes a lot of energy. But based on new modeling results, scientists now report in ACS’ journalEnvironmental Science & Technology that a new system design would require less energy and produce high-quality water.

Guiding EU researchers along the ‘last mile’ to Open Digital Science

Striving to address societal challenges in sectors including Health, Energy and the Environment, the European Union is developing the European Open Science Cloud, a complete socio-technical environment, including robust e-infrastructures capable of providing data and computational solutions where publicly funded research data are Findable, Accessible, Interoperable and Re-usable (FAIR).

New lithium-oxygen battery greatly improves energy efficiency, longevity

CAMBRIDGE, Mass — Lithium-air batteries are considered highly promising technologies for electric cars and portable electronic devices because of their potential for delivering a high energy output in proportion to their weight. But such batteries have some pretty serious drawbacks: They waste much of the injected energy as heat and degrade relatively quickly. They also […]
