Development of new pyrochlore-type electrocatalysts for oxygen evolution reaction in acid
… for their OER performance. Introducing yttrium (Y) in these pyrochlores increased the overall activity and stability. To explain this behavior, X-ray absorption spectroscopy (XAS) and density functional theory (DFT) calculations were used to study the electronic and structural properties …

Extraction of Rare Earth Elements from Aqueous Solutions by Using Hydrometallurgical Techniques
… (Nd), lanthanum (La), praseodymium (Pr), and yttrium (Y), from mixed solutions using the solvent extraction technique. When performed under specific conditions, including an aqueous-organic ratio (A/O) of 1, an extraction time of 120 minutes, and a temperature of 25°C, the extraction rates of …

Geochemical Analysis of Mississippian Cherts and Devonian-Mississippian Novaculites, Southern Midcontinent Region
… lower normalized values. Rare earth element plus yttrium (REY) concentrations normalized to Post-Archean Australian Shales (PAAS) reveal a negative cerium (Ce) anomaly and a positive yttrium (Y) anomaly, which is a signature of seawater, indicating that the Boone cherts may retain a depositional …

Magnetic studies of epitaxial neodymium
… as thin films with either nonmagnetic yttrium (Y) or magnetic praseodymium (Pr) demonstrated magnetic properties hitherto unforeseen. To probe the newly discovered phenomenon, thin films of Nd and NdY alloys have been prepared in one of two orientations: some with the crystallographic c …

Pasture Intake, Digestibility and Fecal Kinetics in Grazing Horses
… when dosing was every 8 h. The internal marker, yttrium (Y) consistently overestimated digestibility (D). The internal markers, n-alkanes, gave a better estimate of digestibility. When the digestibility estimates were combined with the FO estimates to estimate dry matter intake (DMI, kg/d): DMI = …

Non-traditional sources of critical minerals from the Western Canada Sedimentary Basin
… REE, which include the lanthanide elements and yttrium (Y), are currently produced from peralkaline igneous complexes, carbonatites, or ion-adsorption clay deposits and are prized for their unique chemical, magnetic, and catalytic properties. Their primary importance in the energy transition is …

Energetics Calculation of {10-12} Twin Nucleation and Growth in Magnesium and Alloys using Density Functional Theory and Atomistic Simulation
… atoms such as aluminum (Al), zinc (Zn), and yttrium (Y) on {"10" "1" ̅"2" } twin nucleation and growth in magnesium alloys remains unclear. In this work, we perform energetics calculation for {"10" "1" ̅"2" } twin nucleation and growth using molecular dynamics (MD) simulations and Density …

Fecal Kinetics and Digestibilities of Hays and Supplements Estimated by Marker Methods in the Horse
… variation in fecal marker concentration. Third, yttrium (Y) and Yb were tested were tested as internal markers, for the estimation of digestibility of hay and supplements, respectively. Eight horses were fed Diet 1 (orchardgrass/alfalfa mixed, OG) or Diet 2 (tall fescue/alfalfa mixed, TF) in …
