The possibility of testing the thicknesses of nickel coatings under chromium coatings on two-layer (nonferromagnetic-ferromagnetic) bases by the magnetodynamic method has been substantiated theoretically and experimentally. The technique and an instrument have been developed; they provide the inspection of nickel coat…
An extended analysis of the nuclear reaction mechanisms involved within deuteron interaction with nuclei, namely the breakup, stripping, pick-up, pre-equilibrium emission, and evaporation from fully equilibrated compound nucleus, is presented in order to highlight the importance of the direct mechanisms still neglecte…
The process of texture formation in tapes made of a number of binary and ternary copper alloys upon cold rolling to degrees of deformation of 98.6–99% and subsequent recrystallization annealing has been studied. The possibility of designing multicomponent alloys based on the binary Cu-30% Ni alloy additionally alloyed…
The shell thickness-dependent strain distributions of the Au/Ag and Ag/Au core-shell nanoparticles embedded in Al2O3matrix have been investigated by finite element method (FEM) calculations, respectively. The simulation results clearly indicate that there is a substantial strain applied on both the Au/Ag and Ag/Au cor…
Processing of nonlinear conductometric titration curves of aqueous solutions of weak electrolytes (∼10 −4 mol/L) has been developed, accounting for dissociation of water and describing the established protolytic equilibriums involving dissolved carbon dioxide. By the nonlinear regression analysis dissociation constant…
In this work, the band structure of III-V thin films is calculated by atomistic tight-binding (TB) sp3d5s* method. The effect of non-parabolic (NP) dispersion on subband energy level is investigated, by comparing TB results with NP quantization model within the effective mass approximation (EMA). It is found that to m…
In this paper we excite bound long range stripe plasmon modes with a highly focused laser beam. We demonstrate highly confined plasmons propagating along a 50 μm long silver stripe 750 nm wide and 30 nm thick. Two excitation techniques were studied: focusing the laser spot onto the waveguide end and focusing the laser…
The matrix shifts of the H-Xe stretching frequency of noble-gas hydrides, HXeCCH, HXeBr, and HXeI in various noble-gas matrices (in Ne, Ar, Kr, and Xe matrices) are investigated via the hybrid quantum-classical simulations. The order of the H-Xe stretching frequencies is found to be ν(gas) < ν(Ne) < ν(Xe) < ν(Kr) < ν(…
Based on the substrate of Pr:Y 2 SiO 5 upconversion nanomaterials, lithium ion Li(I) doped Pr:Y 2 SiO 5 and TiO 2 nanofilm coated Li,Pr:Y 2 SiO 5 composites were prepared by using a sol‐gel method. X‐ray diffractometer, SEM, and fluorescence spectrometer have been employed to test the crystal structure, microimages, a…
The formation of carbon nanotubes (CNTs), spherical carbon nanocapsules (CNCs), and carbon spheres (CSs) is accomplished by using the method of reactions under autogenic pressure at elevated temperatures (RAPET). A powder mixture of naphthalene and nickel acetate tetrahydrate is dissociated under its autogenic pressur…
Ultrathin (Co90Fe10/Pt)8superlattices composed of alternating CoFe (thickness 0.21 nm) and Pt (thickness 0.23 nm) monolayers were deposited by magnetron sputtering. Superlattices deposited at ultralow sputtering power and high Ar pressure showed perpendicular magnetic anisotropy (PMA) whereas superlattices deposited a…
A simple amphiphilic compound, pyrenesulfonic acid (PSA), interacts with the hydrophobic moiety of a copolymer (sulfonated poly(styrene- b -isoprene- b -styrene), s-SISH) and simultaneously provides hydrophiles of –SO 3 H. Doping 2% PSA to the membranes of s-SISH enhances its very low conductivity by 26 times from 2.0…
The optimal management of cancer in patients with severe heart failure is not defined. This issue is particularly challenging when a diagnosis of limited-stage small cell lung cancer (SCLC) is made incidentally in the context of evaluating patient for candidacy for cardiac transplantation. Limited-stage SCLC is typica…
Abstract The catalyst is recycled and reused in five additional catalytic cycles without loss of activity.
We propose a multi-technique approach based on in-vacuum synthesis of metal oxides to optimize the memristive properties of devices that use a metal oxide thin film as insulating layer. Pulsed Microplasma Cluster Source (PMCS) is based on supersonic beams seeded by clusters of the metal oxide. Nanocrystalline TiO2 thi…
Two assemblies, porphyrin powder/ITO and porphyrin film/ITO, were built by a facile method. The time-resolved photovoltage technique was utilized to prove the behaviour of photo-induced charges in the two assemblies. The photovoltage results show that the porphyrin film/ITO assembly displays a reversal polarity respon…
Ayurveda is an ancient medical treatise, summarizing the art of healing and prolonging life and is practiced in India for more than 5,000 years. It is regarded as an alternative form of medicine. Now the same ayurveda is brought into Ayurvastra, the medical dress. This is the article on Ayurvastra which is the cloth m…
Ferroelectrics, like batio3 (bt) or binatio3 (bnt), were studied in the 1950s and are now revisited, due to the need for lead-free piezoceramics, according to worldwide directives for environmental protection. Poling some of these materials has shown a different physical mechanism than ferroelectric domain orientation…
Water-soluble cationic conjugated poly(phenylene vinylene) (PPV) and cationic fullerene were complexed with negatively charged single stranded DNA and double stranded DNA via electrostatic interactions to achieve photoinduced charge transfer with efficiencies as high as those observed from oppositely charged, cationic…
