source: University of UtahDeposits of designated critical minerals needed to transition the world's energy systems away from fossil fuels may, ironically enough, be co-located with coal deposits that have been mined to produce the fossil fuel most implicated in climate change.Now, research led by the University of Utah has documented elevated concentrations of a key subset of critical minerals, known as rare earth elements, or REEs, in active mines rimming the Uinta coal belt of Colorado and Utah. The work is published in the journal Frontiers in Earth Science.These findings open the possi...

Towards novel promising perovskite-type ferroelectric materials: High-pressure synthesis of rubidium niobate source: Shibaura Institute of TechnologyCapacitors are crucial components in electronic devices such as smartphones and computers. They are made of dielectric materials that polarize on the application of the voltage. Currently, barium titanate (BaTiO3) is the most widely used material for capacitors.Barium titanate belongs to the perovskite group of materials, where a titanium ion resides within an oxygen octahedral cage. The material exhibits displacive-type ferroelectric ...
