Rare-earth elements like neodymium, terbium and dysprosium are crucial to the performance of permanent magnets used in various green-energy technologies hybrid or electric cars. To address supply risk those elements, we applied machine-learning techniques design magnetic materials with reduced neodymium content without dysprosium. However, magnet intended be motors should preserved. We develope...

Ultraviolet and blue light were obtained by nonlinear frequency conversion in a random laser (RL) based on Nd0.10Y0.90Al3(BO3)4 nanocrystalline powder. RL operation at 1062 nm, due to the (4)F3/2 → (4)I11/2 transition of neodymium ions (Nd(3+)), was achieved by exciting the Nd(3+) with a tunable beam from 680 to 920 nm covering the ground state absorption transitions to the (4)F9/2, ((4)F7/2,(4...

Bimodal volcanism in the Santa Maria Province of west-central California occurred when segments of the East Pacific Rise interacted with a subduction zone along the California margin during the Early Miocene (about 17 million years ago). Isotopic compositions of neodymium and strontium as well as trace-element data indicate that these volcanic rocks were derived from a depleted-mantle (mid-ocea...

The isotopic composition of neodymium in the water column of the eastern North Atlantic near the Strait of Gibraltar has been determined for several depths. The data show that the Mediterranean outflow results in a significant shift in eNa(0) toward more radiogenic values of ln3Nd/144Nd in the water column at a 1000-m depth. This corresponds to a depth in the neighborhood of the salinity maximu...

Abstract With the increasing demand for energy-saving technologies, neodymium-iron-boron magnets have been widely utilized in high-efficiency motors. However, reserves of neodymium, which is a rare earth element (REE), are limited; thus, strategy scaling up REE supply highly required. In this study, scenario assessment was conducted to evaluate effect material recycling neodymium from final pro...

Neodymium enriched TiO2 anatase-brookite powders were prepared by unconventional method via using pressurized hot fluids for TiO2 crystallization and purification. The photocatalysts were tested in the CH3OH photocatalytic decomposition and they were characterized with respect to the textural (nitrogen adsorption), structural (XRD, XPS, and Raman spectroscopies), chemical (XRF), and optical (DR...

Tracheal squamous cell carcinoma detected early in a high-risk patient has been treated twice with local neodymium-yttrium aluminium garnet laser therapy with good result so far. Ongoing bronchoscopic monitoring continues.

We present luminescent liquid-crystalline neodymium(III) complexes that contain three β-diketonate ligands and a mesogenic 1,10-phenanthroline ligand. Mesomorphism, including a nematic phase--very rare in lanthanide systems--is driven by the highly anisometric phenanthroline.
