Аннотация: Polymer-based dielectric capacitors play a notable part in the practical application of energy storage devices. Graphene oxide (GO) nanosheets can improve the dielectric properties of polymer-based composites. However, the breakdown strength will greatly reduce with the increase of GO content. Hence, the construction of sandwich structure can enhance the breakdown strength without reducing the dielectric constant. Herein, single-layered and sandwich-structured poly(vinylidene fluoride-co-chlorotrifluoroethylene) (P(VDF-CTFE)) nanocomposites with low content of GO nanosheets (<1.0 wt%) are prepared via employing a straightforward casting method. Compared with the single-layered composites and pure P(VDF-CTFE), the sandwich-structured composites exhibit comprehensively better performance compared. The sandwich-structured composite with 0.4 wt% GO nanosheets show an excellent dielectric constant of 13.6 (at 1 kHz) and an outstanding discharged energy density of 8.25 J cm−3 at 3400 kV cm−1. These results demonstrate that the growth of the dielectric properties is owing to 2D GO nanosheets and the enhancement of breakdown strength due to the sandwich structure. The results from finite element simulation provide theoretical support for the design of high energy density composites.

Аннотация: A solid-state reaction process in Ag/Al multilayer thin films has been investigated by the methods of in situ electron diffraction, simultaneous thermal analysis, transmission electron microscopy and X-ray diffraction with the aim of studying the phase formation kinetics of intermetallic compounds. The sequence of the phase transformations in the solid-state reaction has been established: Ag+Al→(Ag)+(Al)→(Ag)+δ-Ag2Al→μ-Ag3Al. The process of the solid-state interaction has been shown to consist of two steps; each of them is described by a kinetic model of the nth order reactions with autocatalysis. The kinetic parameters of the autocatalytic process of the phase formation for δ-Ag2Al and µ-Ag3Al, have been determined, in particular, their apparent activation energy: 126 kJ/mol and 106 kJ/mol, respectively.

Аннотация: Microcrystals orientation distribution in triclinic vanadium dioxide VO2 (T) films was investigated by polarized Raman scattering with a resolution of few ?m and confirmed by electron backscatter diffraction. Euler angles used to describe the orientation of the crystal were determined by two different techniques and good agreement between the values was achieved. Finally, it was demonstrated that Raman scattering could be used to identify the direction of the lattice vector c for (002) crystals in consequence of the triclinic nature of VO2 (T)

   Перевод заглавия: Prediction of formation of competing phases during the growth of Cr2GaC thin films on MgO(111)

МАХ материалы -- тонкие пленки -- конкурирующие фазы -- энтальпия образования -- хром -- галий -- углерод -- MAX materials -- thin films -- competing phases -- enthalpy of formation -- chromium -- galium -- carbon
Аннотация: MAX-фазы представляют собой семейство тройных слоистых соединений с формальной стехиометрией Mn+1AXn (n = 1, 2, 3…), где М – переходный d-металл; А – p-элемент (например, Si, Ge, Al, S, Sn и др.); Х – углерод или азот [1]. Слоистые тройные карбиды и нитриды d- и p-элементов (MAX-фазы) проявляют уникальное сочетание свойств, характерных как для металлов, так и для керамики, что делает их применение перспективным в космической отрасли в качестве различных покрытий. Получение требуемых свойств MAX-фаз зависит от технологических условий синтеза материала. Для этого необходимо тщательное теоретическое моделирование взаимодействия элементов на границе раздела. Одновременный рост конкурирующих фаз наряду с MAX-фазой может происходить из-за выгодности образования конкурирующих фаз, а также из-за более низко-энергетического интерфейса с подложкой по сравнению с MAX-фазой. В данной работе мы изучаем термодинамическую выгодность конкурирующих фаз и MAX-фазы Cr2GaC в зависимости от химического состава потока атомов. Для изучения этих соединений было необходимо рассмотреть систему Cr-Ga-C. Согласно модели эффективной теплоты образования каждую реакцию образования некоторой фазы можно охарактеризовать энтальпией [2]. Для выяснения наиболее вы-годных к формированию фаз было необходимо произвести расчёт энтальпии для всех возможных реакций. Таким образом, задача состояла в переборе всех возможных реакций между чистыми элементами, доступными в различных соотношениях, в частности, в соотношении, соответствующем заданной стехиометрии MAX-фазы, т. е. Cr:Ga:C=2:1:1. Кроме того, считается, что плотность совпадающих узлов [3; 4] для границ раздела между MAX-фазой, термодинамически выгодными конкурирующими фазами и поверхностью MgO(111) показывает роль интерфейса при определении структурного качества тонкой плёнки MAX-фазы, выращенной на MgO(111).
MAX-phases are a family of ternary layered compounds with the formal stoichiometry Mn+1AXn (n = 1, 2, 3...), where M is a transition d-metal; A is a p-element (for example, Si, Ge, Al, S, Sn, etc.); X is carbon or nitrogen [1]. Layered triple carbides and nitrides of d-and p-elements (MAX-phases) exhibit a unique combination of properties characteristic of both metals and ceramics, which makes their application as various coatings in space industry very promising. Obtaining the desired properties of the MAX-phases depends on the technological conditions of material synthesis. This requires thorough theoretical modelling of the elements’ interaction at the interface. Concurrent growth of competing phases along with the MAX-phase may occur due to the favorability of the formation of competing phases and also be promoted by lower energy interfaces with the substrate in comparison with a MAX-phase. In this work, we study thermodynamic favorability of competing phases and Cr2GaC MAX-phase depending on the chemical composition of the atomic flow. To study these compounds, it was necessary to consider the Cr-Ga-C system. According to the effective heat of formation model, each reaction of the formation of a certain phase can be characterized by enthalpy [2]. To find out the most favorable phases, it was necessary to calculate the enthalpy of all possible reactions. Thus, the task was to sort through all possible reactions between pure elements available in various ratios, in particular, in the ratio corresponding to the given MAX-phase stoichiometry, i.e. Cr:Ga:C=2:1: 1. Moreover, it is considered that the density of near-coincidence sites [3,4] for interfaces between MAX-phase, thermodynamically favourable competing phases and MgO(111) surface shows a role of the interface in the determination of the structural quality of the MAX-phase thin film grown on MgO(111).

Аннотация: The single-walled carbon nanotube-based thin films with a thickness from 11 ± 3 to 157 ± 18 nm have been formed using vacuum filtration. The thermal conductivity of the thin films as a function of thickness and temperature up to 450 K has been studied by the 3ω technique. It has been found that, in the region of 49 nm, the supplied heat from a gold strip started propagating with the high efficiency to the thin film plane. The thermal conductivity of the thin films with a thickness of 49 ± 8 nm was measured using the 3ω technique for bulk samples. It has been found that the thermal conductivity of the single-walled carbon nanotube-based thin films strongly depends on their thickness and temperature. The thermal conductivity sharply (by a factor of ~60) increases with an increase in thickness from 11 ± 3 to 65 ± 4 nm. In addition, it has been observed that the thermal conductivity of the thin film with a thickness of 157 ± 18 nm rapidly decreases from 211 ± 11 to 27.5 ± 1.4 W m–1 K–1 at 300 and 450 K, respectively.

Аннотация: Based on the results of in situ electron diffraction study of the solid-state reaction and electrical resistivity measurements on the Al/Ag thin films with an atomic ratio of Al : Ag = 1 : 3, the temperature of the reaction onset has been established and a model of the structural phase transitions has been proposed. The solid-state reaction begins at 70°C with the formation of the Al–Ag solid solution at the interface between the aluminum and silver nanolayers. It has been found that, in the course of the reaction, the intermetallic compounds γ-Ag2Al → μ-Ag3Al are successively formed. It is shown that the possibility of the formation of the μ‑Ag3Al phase during the solid-state reaction in the Al/Ag thin films depends on the aluminum-to-silver ratio, while the formation of the μ-Ag3Al phase begins only after all fcc aluminum has reacted.

Аннотация: The structure and magnetic properties of CoPt–Al2O3 nanocomposite films synthesized by the annealing of Al/(Co3O4 + Pt) bilayers on a MgO(001) substrate at 650°C in vacuum are investigated. The synthesized composite films contain ferromagnetic CoPt grains with an average size of 25–45 nm enclosed in a nonconducting Al2O3 matrix. The saturation magnetization (Ms ~ 330 G) and coercivity (Hc ≈ 6 kOe) of the films are measured in the film plane and perpendicular to it. The obtained films are characterized by a spatial rotational magnetic anisotropy, which makes it possible to arbitrarily set the easy magnetization axis in the film plane or perpendicular to it using a magnetic field stronger than the coercivity (H ˃ Hc).
