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...

Spectra stable deep-blue light-emitting diodes based on cryolite-like cerium(III) halides with nanosecond d-f emission source：scienceAbstractNext-generation wide color gamut displays require the development of efficient and toxic-free light-emitting materials meeting the crucial Rec. 2020 standard. With the rapid progress of green and red perovskite light-emitting diodes (PeLEDs), blue PeLEDs remain a central challenge because of the undesirable color coordinates and poor spectra stability. Here, we report Cs3CeBrxI6−x (x = 0 to 6) with the cryolite-like structure and stable and tunable c...

source:positive.newsResearchers in the US have finally fulfilled an objective that was set decades ago: the achievement of ‘ignition’ – getting more energy out than you put in – using nuclear fusion.The scientists at the Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), where the experiment took place, are no doubt both excited and relieved to finally fulfil the promise implied by the name of their facility. But how excited should the rest of us be? What does this really mean for the possibility of creating effectively unlimited amounts of clean energy, and what else n...
