\n Although the polygonal shape of epithelial cells has been drawing the attention of scientists for several centuries, only a decade and a half ago it was demonstrated that distributions of polygon types (DOPTs) are similar in proliferative epithelia of many different plant and animal species. In this study, we show that hyper-proliferation of cancer cells disrupts this universal paradigm and results in randomly organized epithelial structures. Examining non-synchronized and synchronized HeLa cervix cells, we suppose that the spread of cell sizes is the main parameter controlling the DOPT in the cancer cell monolayers. To test this hypothesis, we develop a theory of morphologically similar random polygonal packings. By analysing differences between tumoural and normal epithelial cell monolayers, we conclude that the latter have more ordered structures because of their lower proliferation rates and, consequently, more effective relaxation of mechanical stress associated with cell division and growth.

However, realizing the stable static negative capacitance in the non-transient non-hysteretic regime remains a daunting task. The problem stems from the lack of understanding of how the fundamental origin of the NC due to the emergence of the domain state can be put in use for implementing the NC FET.

\n Abstract Ferroelectric domain walls provide a fertile environment for novel materials physics. If a polarization discontinuity arises, it can drive a redistribution of electronic carriers and changes in band structure, which often result in emergent 2D conductivity. If such a discontinuity is not tolerated, then its amelioration usually involves the formation of complex topological patterns, such as flux‐closure domains, dipolar vortices, skyrmions, merons, or Hopfions. The degrees of freedom required for the development of such patterns, in which dipolar rotation is a hallmark, are readily found in multiaxial ferroelectrics. In uniaxial ferroelectrics, where only two opposite polar orientations are possible, it has been assumed that discontinuities are unavoidable when antiparallel components of polarization meet. This perception has been borne out by the appearance of charged conducting domain walls in systems such as hexagonal manganites and lithium niobate. Here, experimental and theoretical investigations on lead germanate (Pb 5 Ge 3 O 11 ) reveal that polar discontinuities can be obviated at head‐to‐head and tail‐to‐tail domain walls by mutual domain bifurcation along two different axes, creating a characteristic saddle‐point domain wall morphology and associated novel dipolar topology, removing the need for screening charge accumulation and associated conductivity enhancement.\n

X-ray diffraction (XRD) measurements of these NiO/C nanocomposites demonstrate the presence of β-NiO. NiO/C nanocomposites are composed of spherical particles distributed over the carbon support surface. The average diameter of nickel oxide spheres increases with the NiO content and are estimated as 36, 50 and 205 nm for nanocomposites with 10, 50 and 80 wt% NiO concentrations, respectively. In turn, each NiO sphere contains several nickel oxide nanoparticles, whose average sizes are 7–8 nm. According to the tests performed using a three-electrode cell, specific capacitance (SC) of NiO/C nanocomposites increases from 200 to 400 F/g as the NiO content achieves a maximum of 60 wt% concentration, after which the SC decreases. The study of the NiO/C composite showing the highest SC in three- and two-electrode cells reveals that its SC remains almost unchanged while increasing the current density, and the sample demonstrates excellent cycling stability properties. Finally, NiO/C (60% NiO) composites are shown to be promising materials for charging quartz clocks with a power rating of 1.5 V (30 min).\n

\n Abstract Due to their outstanding dielectric and magnetic properties, hexaferrites are attracting ever-increasing attention for developing electronic components of next-generation communication systems. The complex crystal structure of hexaferrites and the critical dependences of their electric and magnetic properties on external factors, such as magnetic/electric fields, pressure, and doping, open ample opportunities for targeted tuning of these properties when designing specific devices. Here we explored the electromagnetic properties of lead-substituted barium hexaferrite, Ba 1− x Pb x Fe 12 O 19 , a compound featuring an extremely rich set of physical phenomena that are inherent in the dielectric and magnetic subsystems and can have a significant effect on its electromagnetic response at terahertz frequencies. We performed the first detailed measurements of the temperature-dependent (5–300 K) dielectric response of single-crystalline Ba 1− x Pb x Fe 12 O 19 in an extremely broad spectral range of 1 Hz–240 THz. We fully analyzed numerous phenomena with a corresponding wide distribution of specific energies that can affect the terahertz properties of the material. The most important fundamental finding is the observation of a ferroelectric-like terahertz excitation with an unusual temperature behavior of its frequency and strength. We suggest microscopic models that explain the origin of the excitation and its nonstandard temperature evolution. Several narrower terahertz excitations are associated with electronic transitions between the fine-structure components of the Fe 2+ ground state. The discovered radio-frequency relaxations are attributed to the response of magnetic domains. Gigahertz resonances are presumably of magnetoelectric origin. The obtained data on diverse electromagnetic properties of Ba 1− x Pb x Fe 12 O 19 compounds provide information that makes the entire class of hexaferrites attractive for manufacturing electronic devices for the terahertz range.\n

At room temperature, the strain and the large-signal piezoelectric coefficient reached a maximum of 0.062% and 234 pm V −1 , respectively. Furthermore, enhanced recovered energy density ( W rec = 62 mJ cm −3 ) and high-energy storage efficiency ( η ) of 72.9% at 130 °C were found. The BCZT ceramic demonstrated excellent thermal stability of the energy storage variation (ESV), less than ±5.5% in the temperature range of 30–100 °C compared to other lead-free ceramics. The electrocaloric response in the BCZT ceramic was explored via the indirect approach by using the Maxwell relation. Significant electrocaloric temperature change (Δ T ) of 0.57 K over a broad temperature span ( T span = 70 °C) and enhanced coefficient of performance (COP = 11) were obtained under 25 kV cm −1 .

\n Abstract Since Robert Hooke studied cork cell patterns in 1665, scientists have been puzzled by why cells form such ordered structures. The laws underlying this type of organization are universal, and we study them comparing the living and non-living two-dimensional systems self-organizing at the spherical surface. Such-type physical systems often possess trigonal order with specific elongated defects, scars and pleats, where the 5-valence and 7-valence vertices alternate. In spite of the fact that the same physical and topological rules are involved in the structural organization of biological systems, such topological defects were never reported in epithelia. We have discovered them in the follicular spherical epithelium of ascidians that are emerging models in developmental biology. Surprisingly, the considered defects appear in the epithelium even when the number of cells in it is significantly less than the previously known threshold value. We explain this result by differences in the cell sizes and check our hypothesis considering the self-assembly of different random size particles on the spherical surface. Scars, pleats and other complex defects found in ascidian samples can play an unexpected and decisive role in the permanent renewal and reorganization of epithelia, which forms or lines many tissues and organs in metazoans.\n

We show that the linear mapping is guaranteed between the tube and ribbon bulk resonance when the number of atoms in the tube unit cell is $$2N+4$$ 2 N + 4 , where $$N$$ N is the number of atoms in the ribbon unit cell. Thus, an atlas of carbon nanotubes optical transitions can be mapped to an atlas of zigzag graphene nanoribbons.\n

So far, to study the effect of morphological changes on dielectric and ferroelectric properties in lead-free BCZT ceramics, researchers have mostly focused on the influence of spherical grain shape change.

Scanning electron microscopy (SEM) image showed that BCZT ceramics have kept the 1D rod-like grains with an average aspect ratio of about 4. Rod-like BCZT ceramics exhibit enhanced dielectric ferroelectric (ɛ r = 11,906, tanδ = 0.014, P r = 6.01 μgC/cm 2 , and E c = 2.46 kV/cm), and electrocaloric properties (Δ T = 0.492 K and gZ = 0.289 (K·mm)/kV at 17 kV/cm) with respect to spherical BCZT ceramics. Therefore, rod-like BCZT lead-free ceramics have good potential to be used in solid-state refrigeration technology.\n

We demonstrate how changing on a molecular level the chemical characteristics (composition, intermolecular interaction, spin-orbital interaction) of lead-substituted M-type hexaferrite influences its radio-frequency and terahertz electrodynamic response. Our results indicate a critical temperature range, 50 K {\\textless} T {\\textless} 70 K, where significant changes of the electrodynamic response occur that are interpreted as freezing of dynamical oscillations of bi-pyramidal Fe(2b) ions.

\n We report on the electrodynamic properties of the single crystalline lead-substituted M-type barium hexaferrite, Ba0.3Pb0.7Fe12O19, performed in the broad frequency range including radio-frequency, terahertz and sub-terahertz bands, which are particularly important for the development of microelectronic devices. We demonstrate how changing on a molecular level the chemical characteristics (composition, intermolecular interaction, spin-orbital interaction) of lead-substituted M-type hexaferrite influences its radio-frequency and terahertz electrodynamic response. Our results indicate a critical temperature range, 50 K \\textless T \\textless 70 K, where significant changes of the electrodynamic response occur that are interpreted as freezing of dynamical oscillations of bi-pyramidal Fe(2b) ions. In the range 5–300 K, the heat capacity shows no sign of any phase transition and is solely determined by electron and phonon contributions. An anomalous electrodynamic response is detected at 1–2 THz that features a rich set of absorption resonances which are associated with electronic transitions within the fine-structured Fe2+ ground state and are visualized in the spectra due to magnetostriction and electron–phonon interaction. We show that lead substitution of barium in barium hexaferrite, BaFe12O19, leads to the emergence of a pronounced dielectric and magnetic relaxational dynamics at radio-frequencies and that both dynamics have the same characteristic relaxation times, thus evidencing the bi-relaxor-like nature of Ba0.3Pb0.7Fe12O19.

\n Lead-free Ba0.85Ca0.15Ti0.9Zr0.1O3 (BCZT) ceramics had attracted much attention for the fabrication of microelectronic devices by virtue of their excellent dielectric, ferroelectric and piezoelectric properties. To understand the effects of both mean grain size and grain size distribution on the dielectric properties of lead-free Ba0.85Ca0.15Ti0.9Zr0.1O3 (BCZT) ferroelectric relaxors, an original method was proposed.

\n Pt-based catalysts supported onto various carbon nanotubes (CNTs) and carbon black Vulcan XC-72 have been studied in this work. The samples have been prepared via electrochemical dispersion technique. The carbon nanotubes exhibit the mesoporous morphology with the pore size of 5—30 nm, while Vulcan XC-72 support exhibits a microporous structure. The agglomeration of Pt particles (5—7 nm) is found to be more extended at the carbon nanotubes compared to the carbon black.

The samples have inductive impedances; i.e., their permittivities can be considered negative due to a high conductivity in this frequency range. The permittivity increases in magnitude in magnetic field, and the values of the magnetodielectric coefficient reach 23% at room temperature. The reasons for the effect of magnetic field on the dielectric permittivity of samples are discussed.\n

Вторым важным применением сегнетоэлектрических пленок является их использование при создании принципиально новых микроэлектромеханических устройств (МЕМС). Реализация МЕМС с использованием сегнетоэлектрических наноразмерных пленок в качестве активного элемента по своим параметрам в десятки раз будет превосходить существующие аналоги. В последние годы вопросам стабильности поляризованного состояния и динамики переключения поляризации придается большое значение. В данной работе впервые приведены результаты по исследованию эффекта поля в структуре металл - сегнетоэлектрик - полупроводник, где в качестве сегнетоэлектрика использованы многослойные сегнетоэлектрические слои. Использование многослойных сегнетоэлектрических гетероструктур приводит к самосогласованию поверхностных состояний на границах полупроводник - сегнетоэлектрик и сегнетоэлектрик - сегнетоэлектрик с переключаемой под действием внешнего поля спонтанной поляризацией.

\n Одной из важнейших концепций использования сегнетоэлектрических гетероструктур в микроэлектронике является энергонезависимая память (FeRAM), где в качестве подзатворного диэлектрика в полевом транзисторе используется сегнетоэлектрическая пленка. Вторым важным применением сегнетоэлектрических пленок является их использование при создании принципиально новых микроэлектромеханических устройств (МЕМС). Реализация МЕМС с использованием сегнетоэлектрических наноразмерных пленок в качестве активного элемента по своим параметрам в десятки раз будет превосходить существующие аналоги. В последние годы вопросам стабильности поляризованного состояния и динамики переключения поляризации придается большое значение. В данной работе впервые приведены результаты по исследованию эффекта поля в структуре металл - сегнетоэлектрик - полупроводник, где в качестве сегнетоэлектрика использованы многослойные сегнетоэлектрические слои. Использование многослойных сегнетоэлектрических гетероструктур приводит к самосогласованию поверхностных состояний на границах полупроводник - сегнетоэлектрик и сегнетоэлектрик - сегнетоэлектрик с переключаемой под действием внешнего поля спонтанной поляризацией. Это позволяет создать устойчивое поляризованное состояние с незначительной ее релаксацией.\n

It has been found that different sequences of phase transitions take place in these films. The BST/Pt films demonstrate the same sequence of phase transitions that is observed in the bulk ceramics.

\n A comparative study of the lattice dynamic upon phase transitions in a polycrystalline Ba0.8Sr0.2TiO3 (BST) film on a Pt substrate and in epitaxial BST films grown on various sections of an MgO substrate has been performed by Raman spectroscopy. It has been found that different sequences of phase transitions take place in these films. The BST/Pt films demonstrate the same sequence of phase transitions that is observed in the bulk ceramics. The hardening of a soft mode in BST/(001)MgO and BST/Pt films shows that the transition from the tetragonal ferroelectric phase to the paraelectric phase has features of the displacement-type phase transition and also the order–disorder phase transition. When approaching the ferroelectric transition temperature, the soft mode in the BST/(111)MgO film is softened, following the Cockran law, which indicates the displacement-type phase transition.\n

The group-theoretical analysis of the low-symmetry phases was performed taking into account two order parameters: the polarization related to ionic shifts in polar zone-center F1u mode and the out-of-phase rotation of TiO6 octahedra corresponding to the R25 zone-boundary mode in the parent cubic phase Pm3¯m. The eight-order thermodynamic potential for BST-x solid solutions was developed and analyzed.

\n A phenomenological thermodynamic theory of BaxSr1−xTiO3 (BST-x) thin films epitaxially grown on (111)-oriented cubic substrates is developed using the Landau-Devonshire approach. The group-theoretical analysis of the low-symmetry phases was performed taking into account two order parameters: the polarization related to ionic shifts in polar zone-center F1u mode and the out-of-phase rotation of TiO6 octahedra corresponding to the R25 zone-boundary mode in the parent cubic phase Pm3¯m. The eight-order thermodynamic potential for BST-x solid solutions was developed and analyzed. We constructed the “concentration-misfit strain” phase diagram for BST-x thin films at room temperature and found that polar rhombohedral R3m phase with the polarization normal to the substrate is stable for x > 0.72 and negative misfit strains, while ferroelectric monoclinic C2 and Cm phases with in-plane polarization are stable for much smaller x and positive or slightly negative misfit strains. We constructed the “temperature-misfit strain” phase diagrams for several concentrations (x = 1, 0.8, 0.6, 0.4, and 0.2). Systematic changes of the phase transition lines between the paraelectric and ferroelectric phases are discussed. The phase diagrams are useful for practical applications in thin-film engineering.\n

The possibility of the existence is determined of 305 phases with different types of order in Wyckoff position 8a (including seven binary and seven ternary cation substructures), 537 phases in Wyckoff position 16d (including eight binary and 11 ternary cation substructures), 595 phases in Wyckoff position 32e (including seven binary and four ternary anion substructures) and 549 phases with simultaneous ordering in Wyckoff positions 8a and 16d (including five substructures with binary order in tetrahedral and octahedral sublattices, two substructures with ternary order in both spinel sublattices, and nine substructures with different combined types of binary and ternary order). Theoretical results and experimental data are compared. Calculated structures of the spread types of ordered low-symmetry spinel modifications are given.\n

At room temperature, the polarized Raman spectra of the BT film corresponded to a ferroelectric orthorhombic C2V14 phase with the polar axis oriented in the plane of the substrate. A ferroelectric-paraelectric phase transition in the BT film occurred at ∼450 K. Upon cooling to ∼300 K, a phase transition to the monoclinic Cs3 phase occurred. These experimental results agree well with a theoretical “temperature-misfit strain” phase diagram of the BT film. We found no evidence of phase transitions in the BT/BZ superlattice below room temperature. The phase transition to the paraelectric phase in the BT/BZ superlattice increased in temperature because of lattice mismatch between the BT and BZ layers. A desirable Curie temperature can be tailored rather precisely by varying the layer thicknesses or the BT/BZ ratio in the superlattice. The BT/BZ superlattices are very good for device applications because their ferroelectric phase with in-plane polarization can remain stable at least from 0 K up to 723 K, and even at higher temperatures in superlattices with smaller periodicities.},\n\tnumber = {18},\n\turldate = {2023-11-11},\n\tjournal = {Journal of Applied Physics},\n\tauthor = {Yuzyuk, Yu.

A ferroelectric-paraelectric phase transition in the BT film occurred at ∼450 K. Upon cooling to ∼300 K, a phase transition to the monoclinic Cs3 phase occurred. These experimental results agree well with a theoretical “temperature-misfit strain” phase diagram of the BT film. We found no evidence of phase transitions in the BT/BZ superlattice below room temperature. The phase transition to the paraelectric phase in the BT/BZ superlattice increased in temperature because of lattice mismatch between the BT and BZ layers. A desirable Curie temperature can be tailored rather precisely by varying the layer thicknesses or the BT/BZ ratio in the superlattice. The BT/BZ superlattices are very good for device applications because their ferroelectric phase with in-plane polarization can remain stable at least from 0 K up to 723 K, and even at higher temperatures in superlattices with smaller periodicities.\n

Ni2p3/2,1/2, Co2p3/2,1/2, Cr2p3/2,1/2, and O1s spectra are measured. The spectra are calculated with allowance for multiplet splitting, crystal field, and charge-transfer effect. Ni2+ ions are found to be present in tetrahedral and octahedral positions. Relative numbers of Ni2+ ions in tetrahedral and octahedral sites are determined via fitting the experimental spectra with superposition of the spectra of Ni2+ ions calculated in tetrahedral and octahedral crystal field. Cobalt ions are bivalent and occupy mostly tetrahedral sites. Chromium ions are trivalent and occupy predominantly octahedral positions. However, due to a defective lattice, the samples may contain Cr ions in non-equivalent states, either chemically or structurally.\n

The spectra correlation is obtained using a virtual intermediate planar periodic structure, which has a local symmetry coinciding with that of the tube surface. The method is applied to deduce the zone-center phonon modes of carbon nanotubes from the dispersion branches of the graphene monolayer.

\n A group-theory method to relate the spectra of tubular and parent planar structures is elaborated. The spectra correlation is obtained using a virtual intermediate planar periodic structure, which has a local symmetry coinciding with that of the tube surface. The method is applied to deduce the zone-center phonon modes of carbon nanotubes from the dispersion branches of the graphene monolayer. The results obtained open an additional way for experimental indexing of the carbon nanotubes by means of Raman spectroscopy, and the origin of the Raman-active modes in the achiral nanotubes is determined. We demonstrate that the number of modes in the G band and the relation between their frequencies are governed by the nanotube type. The proposed theory can be easily explored to understand the phonon and electron spectra of many other tubular structures (boron nitride, transition metal dichalcogenides) which have emerged in the past decade.\n

Эти данные указывают на возможность полного внутреннего экранирования связанного заряда Ps.\n

\n Рентгенодифракционными методами и просвечивающей электронной спектроскопией высокого разрешения исследованы наноразмерные сегнетоэлектрические гетероэпитаксиальные пленки Ba0.8Sr0.2TiO3, выращенные по слоевому механизму роста на подложках (100) MgO. Установлено, что при изменении толщины пленок релаксация напряжений происходит посредством образования дислокаций нсоответствия на границе раздела между пленкой и подложкой. Существует критическая толщина (~40 nm) пленок, ниже которой в пленках имеют место напряжения растяжения, а выше - напряжения сжатия. Приведены примеры влияния напряжений на диэлектрические характеристики пленок.\n

Проведенное исследование позволило сделать вывод, что в твердых растворах PST область концентраций с x \\textless 0.04 скорее всего следует рассматривать как гетерофазную.\n

We determine the out-of-plane lattice parameters of the SL constituents by modeling the x-ray diffractograms of the SL’s. The results indicate that the polar c axis of the BT layers lies in the plane of the film. The Raman data reinforces this interpretation. The Raman spectra of SL’s give evidence of coupling between BT and BTZ layers and a narrowing of the Raman peaks suggest a reduction of the disorder of the Ti4+ ions due to the strain. This strain resulting from the lattice mismatch between the constituent layers is responsible for the upward frequency shift of the soft modes, especially the E(1TO) mode, which is markedly altered with respect to its analogs in BT-bulk crystals and BT film. This soft-mode behavior as a function of Λ indicates that the crystal structure of all SL’s is more rigid than in BTZ and BT single thin films.},\n\tlanguage = {en},\n\tnumber = {6},\n\turldate = {2023-11-11},\n\tjournal = {Physical Review B},\n\tauthor = {De Guerville, F. and El Marssi, M. and Raevski, I.

We determine the out-of-plane lattice parameters of the SL constituents by modeling the x-ray diffractograms of the SL’s. The results indicate that the polar c axis of the BT layers lies in the plane of the film. The Raman data reinforces this interpretation. The Raman spectra of SL’s give evidence of coupling between BT and BTZ layers and a narrowing of the Raman peaks suggest a reduction of the disorder of the Ti4+ ions due to the strain. This strain resulting from the lattice mismatch between the constituent layers is responsible for the upward frequency shift of the soft modes, especially the E(1TO) mode, which is markedly altered with respect to its analogs in BT-bulk crystals and BT film. This soft-mode behavior as a function of Λ indicates that the crystal structure of all SL’s is more rigid than in BTZ and BT single thin films.\n

It is found that Ca2+ addition to PbTiO3 films results in a gradual decrease of tetragonality of the perovskite lattice accompanied with a considerable modification of the Raman spectra. A significant difference in Raman spectra of PCT films and available reference data for single crystals (x=0) is explained in terms of the large internal stress, small grain size, and structural disorder produced by Ca2+ substitution.

\n X-ray diffraction (XRD) and Raman scattering in sol–gel derived Pb1−xCaxTiO3 (PCT) thin films are studied as a function of Ca content x. It is found that Ca2+ addition to PbTiO3 films results in a gradual decrease of tetragonality of the perovskite lattice accompanied with a considerable modification of the Raman spectra. A significant difference in Raman spectra of PCT films and available reference data for single crystals (x=0) is explained in terms of the large internal stress, small grain size, and structural disorder produced by Ca2+ substitution. It is found that the shift of the frequency of ferroelectric soft mode correlates well with the variation of tetragonality for x≤xc=0.4. The concentration dependence of the shift is strongly non-linear being qualitatively different from that observed earlier in other A-site doped lead titanate-based systems. According to XRD data, the averaged crystal structure for xc≈0.4 appears as pseudo-cubic, while Raman scattering revealed short-range order tetragonal distortion.
