source:autoevolutionMany companies want a piece of this. So Rice University scientists claim that their process Flash Joule Heating, invented in 2020, “can recover critical metals and recondition anodes in a far more environmentally and economically friendly manner.”Why do batteries die?It doesn’t matter that lithium-ion batteries are powering a smartphone or an EV. They eventually will reach end-of-life because their anodes are becoming useless. Anodes are made from several rare-earth elements, like manganese, nickel, or cobalt, which are combined in different ratios.Basically, charging and d...

source:eurasiareviewMaterials based on rare earth metals and their compounds are of crucial importance to our modern high-tech society. Surprisingly, molecular chemistry of these elements is poorly developed. However, recent progress in this area has shown that this is going to change. In the past years, dynamic developments in the chemistry and physics of molecular rare earth compounds have shifted borders and paradigms that existed for decades.Materials with Unprecedented Properties“With our joint research initiative “4f for Future”, we want to establish a world-leading center that picks up ...

source:manufacturingtodayindiaResearchers at Ruhr University Bochum, Germany, have developed a new concept for switches with an unprecedented speed that becomes conductive thousands of times faster than current state-of-art semiconductor-based switches. Such switches are used in computers, smartphones, and wireless communications.Essentially, a short but powerful laser pulse converts the water into a conductive state within less than a trillionth of a second (10-12 seconds), during which time it behaves almost like a metal.To create the switch, researchers used a highly concentrated sodium iod...
