source:Oak Ridge National LaboratoryScientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel.Promethium was discovered in 1945 at Clinton Laboratories, now the Department of Energy's Oak Ridge National Laboratory, and continues to be produced at ORNL in minute quantities. Some of its properties have remained elusive despite the rare earth element's use in medical studies and long-lived nuclear batt...

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...

Study examines low-permittivity dielectric ceramics for microwave/millimeter-wave communication sourcephys.orgMicrowave dielectric ceramics are the cornerstone of wireless communication devices, widely utilized in mobile communications, satellite radar, GPS, Bluetooth, and WLAN applications. Components made from these ceramic materials, such as filters, resonators, and dielectric antennas, are extensively used in wireless communication networks.As wireless communication frequencies extend into higher bands, signal delay issues become increasingly prominent. Low dielectric constants...
