The theorems of lattice crystallography, which was developed by N.V. Belov, and the wave-mechanical concept of the crystalline state lie in the basis of the crystallographic analysis of structures, which determines the results of atomic ordering by sets of crystallographic planes with the formation of pseudotranslatio…
Thermoelectric effects in bulk silicon are investigated by using a hydrodynamic model for the electron-phonon system, derived in the framework of extended thermodynamics. This model consists of a set of balance equations, where the higher order moments and the production terms are completely determined without any fit…
In most of the ternary (and higher-order) ferromagnetic shape memory alloys (FSMAs) with compositions close to the ${A}_{2}$$BC$ stoichiometry, the austenite phase exhibits L2${}_{1}$-type ordering. Recent investigations of the Co-Ni-Ga FSMA system, however, suggest that the austenite phase has B2-type ordering, altho…
BACKGROUND: Magnetic drug targeting (MDT) is a new treatment principle for tumors. Passive MDT (pMDT) uses cytostatics coupled to ferromagnetic nanoparticles, whereas in active MDT (aMDT), extracorporeal magnets are additionally placed over the tumor area. PURPOSE: Mitoxantrone-magnetite-dextran composite particles we…
A nitrogen-phosphate composite flame-retardant, melamine polyphosphate was prepared through a simpler, less energy-consuming and environment-friendly synthesis method compared with the conventional one. The obtained MPP was characterized by Fourier Transform Infrared spectra (FT-IR) and solid-state NMR, and the conver…
The authors deal with the problem of estimating the zone width of damaged magnetic materials, which is the result of industrial processes adopted for the lamination sheet production. The authors propose two approaches: the former uses the 3D FEM model, while the latter proposes an analytical formula. Both approaches u…
The second-order nonlinear optical (NLO) properties of the Cp*Co(C(2)H(5))(2)C(2)B(4)H(3)-expanded (metallo)porphyrins (Cp* = C(5)Me(5)) have been investigated by using ab inito RHF and density functional theory (DFT) methods. The investigation shows that the compound with expand porphyrin possesses remarkable large m…
The crystal structure, magnetic structure, and magnetic properties of Nd1-xNaxMnO3 (x = 0, 0.15, and 0.20) compounds were studied using magnetization and neutron powder diffraction techniques. The magnetic ordering is found to undergo a transition from A-type antiferromagnetic (AFM) structure for x = 0 to pseudo charg…
Using first-principles method based on density functional theory, we perform a detailed study of the hydrogen storage properties of Li and Ca co-decorated graphene-like carbon nitride (g-CN) nanostructures. The results show that the average adsorption energy of the molecular hydrogen is ∼0.26 eV/H2, which is acceptabl…
In this work, we report on the epitaxial growth of high-quality cubic indium oxide thick films on c-plane sapphire substrates using a two-step growth process. The epitaxial relationship of In2O3 on (0001) Al2O3 has been investigated. The (222) plane spacing and lattice parameter of a most strain-relaxed high-quality I…
Sequentially adsorbed multilayers composed of sodium lignosulfonate (SL) and poly(diallyldimethylammonium chloride) (PDAC) were built up by a layer-by-layer self-assembly technique to investigate the adsorption characteristics of SL microgels for sensitivity improvement. The effect of molecular weight on the adsorptio…
In this investigation, naturally woven coconut sheath, a new type of reinforcement was used. The composite was fabricated using compression molding machine. The mechanical properties like tensile, flexural and impact strengths were studied according to the ASTM standards. For comparison, conventionally used glass fibe…
The correct evaluation of the number of conducting channels in multiwall carbon nanotubes (MWCNTs) is essential in view of the derivation of accurate equivalent circuit models for electrical nanointerconnects made by this innovative material. The authors have recently proposed an approach to evaluate this number for a…
Adsorption of sulfapyridine, tetracycline, and tylosin to a commercial microporous activated carbon (AC) and its potassium hydroxide (KOH)-, CO-, and steam-treated counterparts (prepared by heating at 850°C) was studied to explore efficient adsorbents for the removal of selected pharmaceuticals from water. Phenol and…
Temperature dependent photoluminescence (PL) spectroscopy along with structural investigations of luminescent porous Si enable us to experimentally distinguish between the relative contributions of band-to-band and oxide interface mediated electronic transitions responsible for light emission from these nanostructures…
Abstract The use of raw materials from renewable sources, such as vegetable fibers, for example, has been the subject of several studies and researches. One major disadvantage in the use of vegetable fibers in polymer composites is their hydrophilic nature which provides weak interfacial adhesion in polymer‐fiber comp…
Bubble dynamics is investigated numerically with special emphasis on the static pressure and the positional stability of the bubble in a standing sound field. The bubble habitat, made up of not dissolving, positionally and spherically stable bubbles, is calculated in the parameter space of the bubble radius at rest an…
High performance laminated core materials are nowadays used in several different applications, from some Watts to some Megawatts and from some tens of Hertz to some hundreds of Kilohertz. Cutting laminated or tape wound cores in order to obtain a desired geometry results in higher core losses mainly due to the introdu…
This work presents first-principles investigation of the dynamic process of lithium (Li) penetration through the buffer layer on 6 H -SiC(0001) surface as well as the Li-insertion-induced change of electronic structure. It is found that the penetration is kinetically forbidden for perfect buffer layer because of the s…
It is an important topic to characterize the cross-sectional shape of profiled fiber for quality control of textiles and performance design. In this paper, we propos e a new measure of the shape factor, which can be used to characterize the cross-sections of profiled fibers. Different from the existing indices of the…
