Финансирование Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 19-38-90130.Металлографические исследования выполнены в рамках Программы фундаментальных научных исследований государственных академий наук на 2013-2020 годы, направление III.23.2.Исследования поверхностей разрушения провед…
On-surface synthesis has emerged as a powerful approach to the atomically precise fabrication of molecular architectures with potential applications in nanotechnology. However, it is challenging to synthesize molecular structures that can protrude from the surface such as polymer chains forming by the molecules with u…
Abstract Organic light‐emitting diodes (OLED) are gaining attention and making a significant contribution to the area of lighting and displays technology. The synthesis of new materials that can act as a host as well as emissive materials is crucial and efforts have been made in this direction in this research. Here,…
The study investigated the use of native type (Batek) tobacco (Nicotiana tabacum L.) stalk particles from two different mesh sizes – passing 100 mesh but retained at 200 mesh coded as N-100m (74–149 µm) and passing 200 mesh coded as N-200m (< 74 µm) – as additive with both extender and filler property, as well as form…
Herein, the flatband of a W1N2 crystal is theoretically investigated. It is revealed that the flatband can be well-described by a tight-binding model of the N12 skeleton, where the dispersion of the flatband is governed by both the ppσ bonding strength (Vppσ) and the ppπ bonding strength (Vppπ) between the nearest-nei…
This paper focuses on the experimental determination of the distribution of material, lattice and plastic rotation during deformation of crystalline aggregate. The proposed methodology uses standard electron backscattering diffraction technique combined with 3D digital image correlation data. The presented approach is…
Abstract The structural stability of hydrogen C 2/ c phase from 0 K to 300 K is investigated by combining the first-principles molecular dynamics (MD) simulations and density functional perturbation theory. Without considering the temperature effect, the C 2/ c phase is stable from 150 GPa to 250 GPa based on the harm…
By numerically solving the Bogoliubov--de Gennes equations for the single vortex state in a two-band superconductor, we demonstrate that the disparity between the healing lengths of two contributing condensates is strongly affected by the band Fermi velocities, even in the presence of the magnetic field and far beyond…
The defect-electronic properties of {112} microfaceted surfaces of epitaxially grown ${\mathrm{CuInSe}}_{2}$ thin films are investigated by scanning tunneling spectroscopy and photoelectron spectroscopy techniques after various surface treatments. The intrinsic ${\mathrm{CuInSe}}_{2}$ surface is found to be largely pa…
The dependence of tracer diffusivity ( D ∞ ∼ N – x ∞ ), where probe chains move in an environment of infinitely long matrix chains, and self-diffusion coefficient ( D s ∼ N – x s ), where probe and matrix chains are identical, on the molecular weight of the probe chain N is investigated by using three different molecu…
Abstract Commercial rubber is hardly considered as raw materials to manufacture multifunctional shape‐memory polymers (SMPs) because it is difficult to either tune its glass transition temperature or introduce crystalline domains. Here, we report the manufacture of luminescent SMP composites based on commercial carbox…
TiO2(B) has a high theoretical capacity of 335 mAh g−1 for Li+ intercalation and thus has been considered as a candidate for lithium-ion capacitor and Li-ion battery negative electrodes. For high rate lithium storage, i.e. high power density, it is important to shorten the Li+ diffusion path by using nanostructured Ti…
The control of perpendicular magnetic anisotropy (PMA) of magnetic metals on a platform of perovskite oxides, especially on widely used SrTiO3 substrates, is of technological importance in integrating conventional metal spintronic devices with multifunctional perovskite oxides. In this work, we tuned the magnetic anis…
Poly (4-styrenesulfonic acid) (PSSA) solution with Carbon nanofiber (CNF) were mixed in polyvinylidene fluoride (PVDF) polymer matrix to prepare series of PVDF/PSSA/CNF blend membrane. The results demonstrate improvement in the gauge factor and piezoresistive sensitivity, with increasing concentration of CNF, in prese…
Available safety evaluations regarding mesoporous silica nanoparticles (mSiNPs) are based on the assumption of a relatively high exposure concentration, which makes the findings less valuable in a realistic environment. In this study, we employed Caenorhabditis elegans ( C. elegans ) as a model to assess the neuronal…
In order to improve the durability of coral aggregate seawater concrete (CASC) structures, the influences of exposure time, concrete strength, concrete cover thickness, steel type and inhibitor addition method on the steel corrosion behavior of CASC were investigated and the law of steel corrosion in CASC was obtained…
Indiscriminate overuse of liquid fertilizer and arsenic (As) contaminated soil by abandoned mines is one of the important environmental issues in Korea. This study was carried out to solve these two problems. Amendments (limestone, red mud and acid mine drainage sludge), liquid fertilizer and plant vegetation (Hairy v…
We propose edge expansion parallel cascade selection molecular dynamics (eePaCS-MD) as an efficient adaptive conformational sampling method to investigate the large-amplitude motions of proteins without prior knowledge of the conformational transitions. In this method, multiple independent MD simulations are iterative…
Abstract Hydrogels were prepared by electron beam (EB) radiation to the aqueous solutions of poly(sodium acrylate) in the presence of potassium and ammonium peroxodisulfates. The effects of EB radiation dose, as well as polymer, and initiator concentrations on the formation of gels, were investigated. On the basis of…
Purpose This paper aims to propose a new 3D electromagnetic model to compute translational motion eddy current in the conducting plate of a novel linear permanent magnet (PM) induction heater. The movement of the plate in a DC magnetic field created by a PM inductor generates induced currents that are at the origin of…
