Enhanced relaxor ferroelectric and high energy-storage performance in lead-free Ba0.85Sr0.15Ti0.85Zr0.15O3 ceramic: Correlation between diffuse phase transition and polar nano-region dynamics

Y. Moualhi, F. Bahri, M. Rguiti, H. Rahmouni

Lead-free BaTiO3-based ferroelectrics are promising candidates for environmentally friendly electronic and energy-storage applications. In this study, Ba0.85Sr0.15Ti0.85Zr0.15O3 ceramics were synthesized via the conventional solid-state reaction method to investigate the influence of Sr and Zr…

Equivalence between VMO functions and plurisubharmonic functions with zero Lelong numbers

Séverine Biard, Jujie Wu

<div><p>We prove that a plurisubharmonic function on a domain in the complex Euclidean space is a locally VMO (Vanishing Mean Oscillation) function if and only if its Lelong number at each point vanishes. We also give a global version of this result when the boundary of the domain…

Experimental and DFT study of the structural, electronic, and thermoelectrical properties of Li3xLa2/3-xTiO3 (x = 0.125) ceramic leads free for battery applications

Hicham Kacimi-Naciri, Meriem Ben Zennou, Assia Mabrouk, Amine El Azizi, Mohamed Loutou, Mohammed Mansori, Rachid Amrousse, Nadia Faska, Ahmed Bachar

We synthesized Li3xLa2/3−xTiO3 (LLTO, x = 0.125) via solid-state sintering, yielding a structurally stable orthorhombic perovskite with high environmental compatibility. The resulting material was characterized experimentally through X-ray diffraction (XRD), dielectric measurements (permittivity…

Optimization of explicit RKN schemes to minimize spurious reflections from shock wave propagation on non-uniform grids

Emmanuel Creusé, Mamadou N'Diaye, Juliette Venel, Cédric Hubert, Nicolas Leconte

The propagation of shock waves on non-uniform grids appears, for example, in some impact problems of the fast dynamics type, where a finer mesh can typically be employed in regions of interest, leading to mesh ratios that can range from 10 to 20 or even more. Unfortunately, unwanted spurious…

A BD-entropy inequality preserving Finite Volume scheme for the Quantum Navier-Stokes system

Caterina Calgaro, Robin Colombier, Emmanuel Creusé

In this work, we propose a Finite-Volume scheme on cartesian grids for the numerical approximation of some solutions of the Quantum Navier-Stokes (QNS) equations. An augmented formulation is implemented by introducing an additional drift velocity v, which reduces the third-order quantum operator to…
