Equipment to capture carbon dioxide from ambient air or smokestacks generally works through a sort of reversible filter. Air is passed through granules or a liquid that absorbs the CO 2 , then that CO 2 -loaded substance undergoes a process (usually heating) that causes it to let go of all that CO 2 . The resulting gas can be collected in a separated stream. It’s also possible to do a similar sort of operation on a smaller scale—like inside a battery. A new study from a team led by James Buchen of the University of Delaware demonstrates an example of a battery-based electrochemical carbon-capture technique that they say is more viable than previous attempts. It has the potential to require less energy—and therefore be cheaper—than the reversible-filter designs that currently dominate. Carbon chemistry The basic idea behind a device of this type is that hydroxide produced at the battery cathode reacts with CO 2 , converting it to carbonate or bicarbonate that passes through the separator membrane to the anode. There, the lower pH causes the reaction to reverse, with carbonate turning back into CO 2 gas. The role of the cathode is to produce hydroxide ions; the role of the anode is to consume them.

This mossy green looks great, but the 9 Pro Max is also launching in black and silver. | Image: Honor Honor launches its new Magic 9 flagship phones in China today, and the 9 Pro Max features a design revamp, a capable camera, and a colossal battery. This is Honor's first flagship launch - Robot Phone aside - since it announced its collaboration with camera company Arri. The initial impact is twofold. The new camera island is Arri-inspired, drawing from the "three-lens turret" design first introduced in 1937's Arriflex 35, complete with a knurled texture around the main lens. Arri has played a part in the camera itself, contributing the ability to shoot in Arri LogC3, together with 14 preset Arri Look LUTs, access to Arri's wider library o … Read the full story at The Verge.

EssilorLuxottica, the company that Meta partnered with for its Ray-Ban smart glasses, announced a new version of its Nuance Audio glasses that are designed to double as discreet over-the-counter hearing aids. The new Nuance Audio Plus still manages to squeeze their FDA cleared hearing aid tech into temple arms that don't look much thicker than what you'll find on a standard pair of glasses. But the new Plus option introduces improved sound boosting, better voice clarity, extra on-device controls, and up to 10 hours of battery life. The Nuance Audio Plus are now available in the US in three frame styles including Square, Pathos, and Upturn i … Read the full story at The Verge.
