A new study shows that lithium—a critical element used in rechargeable batteries and susceptible to supply chain disruption—can be recovered from battery waste using an electrochemically driven recovery process. The method has been tested on commonly used types of lithium-containing batteries and demonstrates economic viability with the potential to simplify...

Engineers at the University of California, Davis, have invented a device that can generate mechanical power at night by linking the natural warmth around us to the cold depths of space. The invention could be used, for example, to ventilate greenhouses or other buildings. The work is described Nov. 12...

Electronic signs are all around us, giving directions or advertising the latest gadget. In ACS Energy Letters, researchers report that they've developed a dynamic display technology that dissipates heat instead of generating it when the color changes, cooling the surface underneath. They also showed the display could be attached to...

Electrolyzers, devices that use electricity to drive desired chemical reactions, could enable the production of clean hydrogen (H2) gas from water (H2O) and the conversion of carbon dioxide (CO2) into useful fuels or industrial chemicals. When it comes to the reduction of CO2, the greenhouse gas can be first converted...

A new study published in Environmental Research Letters finds that continued growth in artificial intelligence (AI) use across the United States could add approximately 900,000 tons of CO₂ annually. This is not a small amount but equates to a relatively minor increase when viewed in the context of nationwide emissions....
