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...

source:Tech ploreA University of Virginia-led research team has developed new protective coatings that allow turbine engines to run at higher temperatures before components begin to fail."Hotter engines are more efficient," said Elizabeth J. Opila, professor and chair of the Department of Materials Science and Engineering at UVA and a lead researcher on the project.Turbine engines are known for aircraft propulsion, but stationary turbines have many industrial uses, including power generation. They burn fuel to rotate turbine blades, converting mechanical energy to electricity."Y...
