Crystal Structure and Spectroscopic Characterization of a New Hybrid Compound, (CHN)[CdBr], for Energy Storage Applications.

Organic-inorganic hybrid materials have recently found a vast variety of applications in the fields of energy storage and microelectronics due to their outstanding electric and dielectric characteristics, including high dielectric constant, low conductivity, and low dielectric loss. However, despite the promising properties of these materials, there remains a need to explore novel compounds with improved performance for practical applications. In this research paper, the focus is on addressing this scientific challenge by synthesizing and characterizing the new-centrosymmetric (CHN)[CdBr] crystal.

A novel optical temperature sensor and energy transfer properties based on Tb/Sm codoped SrY(MoO) phosphors.

A series of SrY(MoO) phosphors doped and co-doped with Tb/Sm ions was synthesized to develop new optical temperature sensor materials. The structures, morphologies, and luminescent characteristics of these phosphors were thoroughly investigated. Luminescence spectra of mono-doped SrY(MoO) phosphors were measured under the excitation at 375 and 403 nm corresponding to direct excitation of Tb and Sm, respectively.

Influence of Nd Substitution on the Phase Constitution in (Zr,Ce)FeSi Alloys with the ThMn Structure.

Iron-based compounds with a ThMn-type structure have the potential to bridge the gap between ferrites and high performance NdFeB magnets. From the point of view of possible applications, the main advantage is their composition, with about 10 wt.% less rare earth elements in comparison with the 2:14:1 phase.

Two-step single-reactor synthesis of oleic acid- or undecylenic acid-stabilized magnetic nanoparticles by thermal decomposition.

Different iron oxides (i.e., magnetite, maghemite, goethite, wüstite), particularly nanosized particles, show distinct effects on living organisms.

The Effects of Various Parameters of the Microwave-Assisted Solvothermal Synthesis on the Specific Surface Area and Catalytic Performance of MgF Nanoparticles.

High-specific-surface-area MgF was prepared by microwave-assisted solvothermal synthesis. The influences of the solvent and the magnesium precursors, and the calcination atmospheres, on the nanoparticle sizes and specific surface areas, estimated by X-Ray Powder Diffraction, N sorption and TEM analyses, were investigated. Nanocrystallized (~7 nm) magnesium partially hydroxylated fluorides (MgF(OH)) with significant specific surface areas between 290 and 330 m∙g were obtained.
