We investigated the influence of solvent on the activity, epoxide selectivity, and H2O2 efficiency of three types of zeolites—TS-1, Ti-Beta, and Ti-MWW—in the liquid-phase epoxidation of 1-hexene and cyclohexene. We found that the effect of solvent not only was related to the hydrophilicity/hy...

A novel rhodium-catalyzed oxidative [5 + 1] annulation of 2-vinylanilines with α-diazocarbonyl compounds for the construction of quinoline-2-carboxylate derivatives has been developed. A series of functional groups such as methyl, methoxy, fluoro, chloro, bromo, cyano, and even thienyl substitu...

This study demonstrates the formation of barrier-type anodic films in a phosphate buffer (pH 8.4) on thermally evaporated aluminium-holmium alloys covering a 2.0–12.0 at.% Ho compositional spread. Scanning x-ray diffraction and scanning electron microscopy reveal that structure and morphology o...

Low temperature heat capacity of erbium phosphate ErPO4 was measured by relaxation calorimetry (2–35 K) and adiabatic calorimetry (5–345 K). High-temperature enthalpies of this substance were studied by drop calorimetry in the region of 357–1575 K. Smoothed thermodynamic properties (heat capa...

Rare-earth phosphates with the general formula REEPO4·nH2O belong to four distinct structural types: monazite, rhabdophane, churchite, and xenotime. We report herein the first direct comparison between vibrational spectra of these compounds for the same metal cation i.e. gadolinium. The four Gd...

Human provenance studies employing isotopic analysis have become an essential tool in forensic and archaeological sciences, with multi-isotope approaches providing more specific location estimates compared to single isotope studies. This study reports on the human provenancing capability of neod...

The present work describes the sintering and ionic conductivity of rare-earth-based fluorobritholite (Sr8La2-xNdx(PO4)4(SiO4)2F2 with 0 ≤ x ≤ 2). The materials were prepared via conventional solid state reactions. The analysis and characterization of the synthesized powders were carried out us...

Nd3+-doped oxyfluoro-titania-phosphate glasses with a chemical combination, P2O5–CaF2–BaF2–TiO2–Nd2O3 (PCfBfTiNd), were synthesized by the regular melt-quenching method. These glass samples were investigated through optical absorption, emission, decay curves and spectroscopic ellipsometry an...

In the present study we analyzed the effect of structural distinction in neodymium nanostructures for modulating angiogenic process as the strategy for identifying biocompatible Nano therapeutics for biomedical applications. We observed structural dependence of Nd nanoparticles on biocompatibili...

The purpose of this study was to investigate the separation of Co, Nd and Dy from a ternary Co-Nd-Dy solution using amorphous zirconium phosphate (am-ZrP). Am-ZrP was synthesized by a precipitation method at room temperature and subsequently characterized by Fourier transform-infrared spectromet...

The iron–neodymium alloy is generally used for magnets. Neodymium is one of the rare earth elements; since these elements are precious metals and therefore rare and expensive, recycling processes are often used to save costs. There are a few reported processes for the recycling of rare earth el...

Iron-neodymium alloys are generally used for producing magnets. Neodymium falls under the class of rare earth elements, which are precious and expensive, and are thus often recovered by recycling processes as a cost saving measure. There are a few reported processes for the recycling of rare ear...
