Correlations in Magnetic Sub‐Domains as an Unconventional Phase Diagram for van der Waals Ferromagnets

open access: yesAdvanced Science, EarlyView.
An unconventional magnetic order is observed in exfoliated CrBr3 layers, characterized by vertically correlated planar magnetic sub‐domains. Magnetic force microscopy, ab initio calculations, and micromagnetic simulations indicate that these sub‐domains arise from stacking faults modifying interlayer exchange coupling.

Stalinism in Poland

open access: yesThe Person and the Challenges. The Journal of Theology, Education, Canon Law and Social Studies Inspired by Pope John Paul II, 2019
The article presents, in a synthetic manner, the mechanism of introducing the Stalinist system in Poland and describes its essence. It points to the importance of – until now given less value in the relevant literature – the mechanism of elimination of institutions and persons representing the constitutional order and state-creating social fabric, as ...

Aromaticity‐Dependent Memristive Switching

open access: yesAdvanced Electronic Materials, EarlyView.
The article describes a resistive switching mechanism based on the creation of virtual filaments. Research consists of experimental and theoretical data supporting the theory that resistance of the memristor can be modulated by a redox‐induced aromaticity change of a working material.

Prevalence of vascular disruption anomalies and association with young maternal age: A EUROCAT study to compare the United Kingdom with other European countries

open access: yesBirth Defects Research, Volume 114, Issue 20, Page 1417-1426, December 1, 2022., 2022
Abstract Background Younger mothers are at a greater risk of having a pregnancy with gastroschisis and the risk is higher in the United Kingdom than other European countries. Gastroschisis is thought to be a vascular disruption anomaly and the aim of this study was to analyze the prevalence of other possible vascular disruption anomalies to determine ...

First detection of porcine circovirus type 3 on commercial pig farms in Poland

open access: yesTransboundary and Emerging Diseases, 2017
Porcine circovirus type 3 (PCV3) is a novel circovirus species recently discovered in USA and China in cases of porcine dermatitis and nephropathy syndrome, reproductive failure, respiratory disease and multisystemic inflammation.

Layer‐By‐Layer Approach to Improve the Capacitance of Conducting Polymer Films

open access: yesAdvanced Electronic Materials, EarlyView.
This work describes the synthesis and characterization of a composite material based on poly(3,4‐ethylenedioxythiophene) (PEDOT) and poly(3,4‐ethylenedioxypyrrole) (PEDOP) deposited in a layer‐by‐layer approach. Due to the developed electroactive area coming from the presence of 3D nanostructures, PEDOT/PEDOP demonstrates superior areal capacitance ...

Ultrathin High‐Efficiency Zener Diode Fabricated Using Organized ZnS Nanoparticles in Surface‐Grafted Poly(methacrylic acid) Matrix

open access: yesAdvanced Electronic Materials, EarlyView.
This work presents a unique approach for fabricating homogeneously dispersed ZnS nanoparticles within an ultra‐thin (<40 nm) polymer matrix. The uniformity of dispersion is ensured through post‐polymerization substitution of Zn2⁺‐terminated side groups in surface‐grafted PMAA brushes. Due to the homogeneous distribution of semi‐conducting nanoparticles,
