Wake-Up Free Ultrathin Ferroelectric HfZrO Films.

The development of the new generation of non-volatile high-density ferroelectric memory requires the utilization of ultrathin ferroelectric films. The most promising candidates are polycrystalline-doped HfO films because of their perfect compatibility with silicon technology and excellent ferroelectric properties. However, the remanent polarization of HfO films is known to degrade when their thickness is reduced to a few nanometers.

[The competence in health issues of population of circumpolar region of the Russian Federation].

The health literacy of citizen is determined by a set of demographic and social factors. The deficiency of health literacy of population in the Russian Arctic Zone conditions delay in indicators characterizing population health from their all-Russian values and menaces ability to achieve the targets of the National Strategy of Development of Russian Arctic Zone and Ensuring National Security up to 2035.The purpose of the study is to assess level of health literacy of patients and healthy population residing in circumpolar territories of Russia (Arkhangelsk Oblast).

A-Site Cation Size Effect on Structure and Magnetic Properties of Sm(Eu,Gd)CrMnFeCoNiO High-Entropy Solid Solutions.

Three high-entropy Sm(Eu,Gd)CrMnFeCoNiO perovskite solid solutions were synthesized using the usual ceramic technology. The XRD investigation at room temperature established a single-phase perovskite product. The Rietveld refinement with the FullProf computer program in the frame of the orthorhombic Pnma (No 62) space group was realized.

Polysubstituted High-Entropy [LaNd](CrMnFeCoNi)O Perovskites: Correlation of the Electrical and Magnetic Properties.

La-, Nd- and La/Nd-based polysubstituted high-entropy oxides (HEOs) were produced by solid-state reactions. Composition of the B-site was fixed for all samples (CrMnFeCoNi) with varying of A-site cation (La, Nd and LaNd). Nominal chemical composition of the HEOs correlates well with initial calculated stoichiometry.

Early-Stage Growth Mechanism and Synthesis Conditions-Dependent Morphology of Nanocrystalline Bi Films Electrodeposited from Perchlorate Electrolyte.

Bi nanocrystalline films were formed from perchlorate electrolyte (PE) on Cu substrate via electrochemical deposition with different duration and current densities. The microstructural, morphological properties, and elemental composition were studied using scanning electron microscopy (SEM), atomic force microscopy (AFM), and energy-dispersive X-ray microanalysis (EDX). The optimal range of current densities for Bi electrodeposition in PE using polarization measurements was demonstrated.
