source:universetodayA new particle accelerator at Michigan State University is producing long-awaited results. It’s called the Facility for Rare Isotope Beams, and it was completed in January 2022. Researchers have published the first results from the linear accelerator in the journal Physics Review Letters.Physicists sometimes describe isotopes as different flavours of the same element. An atom of any element always has the same number of protons in its nucleus, but the number of neutrons can vary. Atoms of the same element with different numbers of neutrons are called isotopes. Carbon, for e...

source:natureAbstractThis article presents a resource for automated search, extraction and collation of geochemical and geochronological data from the Figshare repository using web scraping code. To answer fundamental questions about the Earth’s evolution, such as spatial and temporal evolution and interrelationships between the planet’s solid and surficial reservoirs, researchers must utilize global geochemical datasets. Due to the volume of data being published, these datasets become quickly outdated. We present a resource that allows researchers to rapidly curate and update their own databa...

source:natureAbstractIn this study, calcium carbonate, sepiolite, and commonly used diatomite (DE) carriers were mixed to prepare calcium carbonate or sepiolite mixed DE/nano-titanium dioxide (TiO2). The analyses of X-ray diffraction and scanning electron microscope confirmed that the particle size of nano-TiO2 was about 20–24 nm in DE/nano-TiO2, and the particles were relatively uniform. When (calcium carbonate and sepiolite + DE)/nano-TiO2 was used, the Ti content in the composite remained unchanged, while the particle size of nano-TiO2 increased to a certain extent. Among them, the use of (...

source:innovationnewsnetworkCritical minerals, including rare earth elements, are essential to the US’ economy and national security as they are used in a variety of everyday applications. Due to their necessity, researchers are looking for new ways to extract these metals to ensure that supply is guaranteed. Now, researchers from Penn State’s Center for Critical Minerals have developed a new purification process that extracts rare earth oxides from acid mine drainage and associated sludges at purities of 88.5%The findings, titled ‘Selective recovery of high-grade rare earth, Al, and Co-Mn fro...
