By testing fabric extraction properties, the PhabrOmeter Fabric Evaluation System offers the potential for routine objective evaluation of fabric handle. In this paper, a series of simple linear models has been developed using fabric extraction curve data for a series of lightweight next-to-skin knitted wool fabrics.…
The effects of surface modification of jute fibers and nanoclay on jute–biopol green composites are evaluated by the thermal and interlaminar shear strength (ILSS) characterizations. Four subsequent chemical treatments including detergent washing, dewaxing, alkali treatment, and acetic acid treatment were performed to…
The effects caused upon the physicochemical behavior of high-density polyethylene pipes by exposure to a diesel lubricant were investigated, as a function of time and temperature, by thermogravimetric and gravimetric analysis and by FT-IR. The gravimetric data were satisfactorily described using Fick's law. The fittin…
Polyamide nanocomposites with different octakis(dimethylsiloxy, 3-glycidoxypropyl)octasilsesquioxanes (POSS) contents (0.5, 2, 4 wt. %) were obtained during melt blending. SEM results showed that POSS are uniformly dispersed in polyamide 6 matrix (Fig. 1). FT-IR and DSC analysis indicated that the addition of POSS pro…
Magnesium AZ31 sheets have been lap welded with magnetic pulse welding using H shaped symmetric coils connected to a Pulsar MPW-25 capacitor bank. The joints displayed an increasing trend in strength with discharge energy. The weld morphology consisted of twin bond zones separated by an unbonded centre zone. Metallogr…
Nanoparticles, compared to micro particles have distinctly different properties and advanced characteristics. Silver nanoparticles are one of the metal nanoparticles which has varied and different properties when compared to other material. Silver nanoparticles have received considerable attention due to their attract…
The UV-vis spectra of a series of subporphyrazines, SubPz(A,R), and subphthalocyanines, SubPc(A,R) ( A = F, Cl; R = H, F, CH 3 , C 3 H 7 , SCH 3 , SC 2 H 5 and SPh), where A is the substituent attached to the central boron atom and R is the substituent attached to the periphery of the molecule have been analyzed throu…
The influence of multiferroic bismuth ferrite (BiFeO 3 ) nanoparticles (NPs) on the electro-optical (EO) and dielectric properties of an orthoconic antiferroelectric liquid crystal (OAFLC) mixture is investigated in planar cells. It is shown that dispersion of NPs in OAFLC lead to modifications of response time, spont…
The occurrence of more than 15 natural nuclear Reactor Zones (RZ) in a geological environment remains a mystery even 40 years after their discovery. The present work gives for the first time an explanation of the chemical and physical processes that caused the start-up of the fission reactions with two opposite proces…
The possibilities of applications of vibrational spectroscopy techniques in the analysis and characterization of polymers are reviewed. The basic principles of the methods of Raman, mid-infrared, and near-infrared spectroscopies are briefly explained. Important aspects concerning qualitative and quantitative analysis…
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…
