Mg3Al2Si3O12 jeffbenite inclusion in super-deep diamonds is thermodynamically stable at very shallow Earth’s depthssource:natureAbstractJeffbenite (having the same chemical composition of pyrope, ~ Mg3Al2Si3O12, and also known as TAPP phase) is a mineral inclusion only found in diamonds formed between about 300 and 1000 km depth) and is considered a stable phase in the transition zone (410–660 km depth) and/or in the shallowest regions of the lower mantle (around 660–700 km depth). This rare and enigmatic mineral is considered to be a pressure marker for super-deep diamonds and therefore it ha...

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 ...
