Abstract In this work, we explore the physical properties of RbXH 3 (X=Cr, Zr) perovskite hydrides for solid‐state hydrogen storage. The structural, mechanical, electronic, optical, and storage were theoretically investigated using density functional theory CASTEP software. selected candidates fully relaxed optimized in cubic phase space group Pm‐3 m. structural stability was verified by means thermodynamic, dynamic mechanical stabilities. Mechanical analyses based on Poisson's ratio (ν),...
Abstract All‐solid‐state lithium‐ion batteries, employing solid electrolytes, offer a promising solution to address safety concerns inherent in conventional batteries. Among the various types of Li‐ion LiTi 2 (PO 4 ) 3 (LTP) with Na Super Ionic CONductor (NASICON) structure stands out as particularly attractive material, despite its relatively low ionic conductivity at room temperature. One approach enhance performance LTP electrolytes involves modifying network size or redistributing Li...
Actinide oxalate decomposition under hot compressed water is proposed as a milder production route for nanometric sized (mixed) actinide oxides.
Abstract To assure the safety of oxide-fuel based nuclear reactors, knowledge atomic-scale properties U 1−y M y O 2±x materials is essential. These compounds show complex chemical properties, originating from fact that actinides and rare earths may occur with different oxidation states. In these mostly ionic materials, aliovalent cationic configurations can induce changes in oxygen stoichiometry, dramatic effects on fuel. First studies Am indicated exhibit particularly electronic...
An approach for Raman measurements of highly radioactive samples is presented here. The innovative part this lies in the fact that no single equipment direct contact with sample, as sample sealed an alpha‐tight capsule. analysis effectively performed through optical‐grade quartz window closing This allows performing micro‐Raman on limitations laser source wavelength, polarisation mode, spectrometer mode and microscope (provided focal length objective greater than thickness sub mg samples)....
The electric field has a large effect on the stoichiometry and grain growth of UO2+x during Spark Plasma Sintering. is gradually reduced to UO2.00 as function sintering temperature time. A gradient in oxidation state within pellets observed intermediate conditions. shape depends unequivocally direction electrical field. positive surface pellet shows higher compared negative one. An area with larger size found close electrode, but not contact it. We interpret these findings redistribution...
Abstract This study presents a comprehensive analysis of the structural, mechanical, electronic, and optical properties GaXF 3 compounds (where X = Ca Sr), which belong to perovskite halogenide family with gallium as base element. The structural stability GaCaF GaSrF was confirmed through Birch–Murnaghan equation‐of‐state optimization using density functional theory (DFT) implemented in CASTEP. Mechanically, these exhibit notable ductility, scratch resistance, anisotropy, mechanical...
Abstract A reliable method to probe and characterise the oxidation of actinide oxides by means Raman spectroscopy is introduced. The present so‐called laser heating enables studying behaviour various compounds at high temperatures under a given atmosphere with unique alteration small amount sample, which certainly advantageous in terms safety when handling hazardous or radioactive materials. approach based on dual use beam, same time employed as excitation source for analysis source,...
The non-linear variation of the lattice parameter in U<sup>IV</sup>O<sub>2</sub>–Bi<sub>2</sub>O<sub>3</sub> system under inert atmosphere is due to uranium oxidation.
Herein, a series of perovskite‐type hydride materials RMnH 3 ( R = Ca, Sr, and Ba) are investigated by density functional theory for solid‐state hydrogen storage. Their structural, mechanical, electronic, optical properties calculated their thermodynamic, dynamic, mechanical stability is assessed. All compounds crystallize in the undistorted cubic perovskite system with Pm‐3m symmetry. The results from properties, based on parameters such as Poisson's ratio ν ) G/B ratio, indicate that CaMnH...
