Combining APCS-MLR model to evaluate the distribution and sources of rare earth elements in a large catchment source:sciencedirectAbstractRare earth elements (REEs), functioning as indicators for environmental tracking, revealing the impacts of human activities on changes in aquatic ecosystems. However, systematic research on the geochemical characteristics of REEs in large river basins remains relatively scarce. Therefore, this research investigates the geochemical properties of REEs within the Yangtze River basin, analyzing the quantity and spatial distribution of REEs in surface aquati...

source:Communications MaterialsAbstractDoping of luminescent materials by rare-earth ions is common practice to achieve desired emission properties for a large variety of applications. As several rare-earths ions are frequently combined, it is subsequently difficult to effectively detect and control their homogeneous distribution within the host material. Here, we present a simple, rapid, large scale and precise method of rare-earth mapping using a commercial UV-Vis scanner. We discuss the influence of rare-earth distribution on the physical, optical and luminescent properties with no observab...

source:Scientific ReportsAbstractAerospace and marine industries are constantly in search of materials that can provide good strength and durability while also being lightweight. Aluminium composites with adequate reinforcements have been proven to be effective in achieving incredible mechanical properties while also maintaining a good strength to weight ratio. Numerous studies have been done to study the various possibilities of matrix reinforcement combinations in aluminium composites. This work focuses on studying the effect of varying Cerium Oxide (CeO2) percentage in the aluminium composi...

source:University of GothenburgThe global pursuit of rare-earth metals, which are crucial for the manufacturing of green technologies, may carry an unexpected risk for our future health. Roelof Coertze, a researcher at the Centre for Antibiotic Resistance Research (CARe), has been awarded 6 million SEK from Formas to investigate how these metals could potentially contribute to the development of antibiotic resistance - one of the greatest public health challenges of our time.Since the discovery of antibiotics, millions of lives have been saved, but extensive and irresponsible use has enabled b...
