Solvent extraction behaviors of metals from the leaching solution of super alloys which are increased to the industry of automobiles and the others were investigated to the recovery of metal ions. The effects on the concentration of extractants, pH of aqueous phase, concentration of HCl in aqueous phase and impurities…
The paper presents the peculiarities of the temperature dependence for the second harmonic generation efficiency of focusing laser radiation. It is shown that an asymmetry of the dependence is the result of the vector phase-matching process near the crystal axis.
The 5-50 μm-thick layers of a nanomaterial consisting of acrylic paint and multilayer carbon nanotubes (~3 mass.%) are investigated. It is shown that laser radiation and heat treatment enhance the conductivity of the layers by a few orders of magnitude. The layers remain stable in water for over 200 h and exhibit a co…
The Zernike method using a nematic liquid crystal (NLC) filter with orientational optical nonlinearity was applied to visualize phase objects. It was shown that the contrast sign of the image switches by means of varying the incidence angle of a light beam on liquid crystal cell. The comparison of a contrast sign chan…
Optical vortices were generated by means of photoinduced point defects in orientation of the nematic liquid crystal (NLC). The axisymmetric distribution of NLC director field was produced due to photorefractive effect in NLC or due to isotropic channel formation in light absorbing NLC.
Summary form only given. Triple probes are a useful diagnostic tool to measure the ion density ni and electron temperature Te in low-pressure plasmas without the necessity to obtain a probe I-V characteristic. This can give advantages over single and double Langmuir probes for the measurement of fast, non-periodic eve…
Meios difusivos com fontes distribuídas, tal como o caso das células de combustível nucleares, possuem um importante papel na Engenharia. Devido à fissão nuclear do elemento químico, células combustíveis são capazes de liberar altas taxas de energia térmica apesar de suas pequenas dimensões, de tal maneira que a máxim…
Summary form only given. To date, methane is the most commonly adopted hydrocarbon for H2generation. Apart from conventional processes of methane reforming, plasma processing is a new efficient technique, which can be used for converting hydrocarbons and organics into syngas. Most of published investigations on hydroc…
High sensitivity deep ultraviolet (DUV) photodetectors operating at wavelengths shorter than 280 nm are useful for various applications, including chemical and biological identification, optical wireless communications, and UV sensing systems (1). While semiconductor avalanche photodiodes (APDs) can be more compact, l…
Transparent conductive electrodes (TCEs) are ubiquitous and essential for photonic devices like solar cells, touchscreens and photodetectors. An increasing demand for TCEs may be met with graphene, which promises low production cost and an abundance of raw material and may enable flexible optoelectronic devices. We re…
Summary form only given. Accelerated global warming resulted in diverse regulations for possible removal of greenhouse gases. N2O is one of global warming gases that is produced in the course of combustion process and incomplete reduction of NOx. Removal of N2O has been tried via catalytic reaction of N2O decompositio…
The properties of AlTiN films by a cathodic arc deposition process have been studied. Oblique angle deposition has been applied to deposit AlTiN films. AlTiN films have been deposited on stainless steel (SUS304) and cemented carbide (WC) at a substrate temperature of 500℃. AlTiN films were analyzed by scanning electro…
Hexeneuronic acid in soda-anthraquinone(AQ) pulps from Moso bamboo(Phyllostachys pubescebs), Timber bamboo(Phyllostachys bambusoides) and Henon bamboo(Phyllostachys nigra var. henonis) was investigated with mercuric chloride hydrolysis and UV spectroscopic quantification. Concentration of hexeneuronic acid in bamboo p…
In this article, a novel environmently friendly anhydride free, solventless free epoxy impregnating resin was developed by synthesizing a novel epoxy resin with high reactivity and heat resistance, then combining with environment friendly epoxy cross-linking monomers and effective initiator-inhibitor. The new resin ha…
The system of conjugated stucked screens with rotational symmetry is considered to rotate polarization of the insident plane wave. It is discussed connection between the symmetry of the structure and its polarization response. The new dihedral eigenmodes, which are origin of the such resonant behaviour are investigate…
Nonlinear optical properties of subphthalocyanines coupled with gold nanoparticles have been studied. We have found out many-fold enhancement in the saturable-absorption effect which originated from the strong near-field and great increase in the decay rate of excited states. Such plasmon-induced phenomenon gives the…
With, is technologically very complex and energy-intensive subsequent high temperature heat treatment of welded joints made of the apparatus. It is shown that the developed technology of welding with RTTS in automatic welding in shielding gases, welding wires austenitic heat-resistant steel 15H5M martensitic structura…
Abstract Solid–liquid phase transition has been simulated by the molecular dynamics method, using isobaric–isoenthalpic ensemble. For interatomic potential, glue potential has been selected. The original algorithm for bookkeeping of the information on neighbouring relationships of the atoms has been developed and used…

In this paper we present an experimental method of determining losses caused by 1D gratings based on applying those gratings as output couplers of THz lazers. Firstly we experimentally determined the optimal coupling coefficient for two types of gratings: wire gratings and strip gratings on dielectric substrates. Ther…
