In this study, molybdenum oxide thin films are deposited by using high power impulse magnetic sputtering (HiPIMS) at different pulses length of 60, 90, 120, 150 and 180 μs on glass substrates in a combination of reactive and non-reactive gases with a ratio of O2/Ar = 0.66. The structural and optical properties of thes…
The aim of this paper is to study of possibilities of near-field microwave probing in the estimation of skin structure in man and rats. Results: We studied real part of dielectric permittivity of the skin and subcutaneous elements of healthy people and Wistar rats at depths of 2 to 5 mm with resonance near-field micro…
The paper presents the results of research on the structure and selected properties of magnetic alloys based on Fe. The alloy with the chemical composition Fe 36 Co 36 Y 8 B 20 was produced using two methods: forcing and sucking the liquid alloy into a copper mould. The alloy was cast in the form of 10 mm 5 mm 0.5 mm…
Wear conduct of Austempered Ductile Iron (ADI) balls in the grinding of iron ore in a ball mill process was examined as a function of microstructure developed by carrying out 2-stage asutempering heat treatment. Various microstructure of ADI are produced by austenitising SG (spheroidal ghaphite) iron balls at 9200 C f…
Ama: Periferal sinir hasar ciddi bir salk sorunu olup hastann hayat kalitesini ciddi olarak etkilemektedir. Periferal sinir hasar ok yava iyileir ve iki sinir ucu arasnda mesafe oksa, hi iyileemez. Bu sebeple, sinir hasarnn tedavisi iin farkl stratejiler gelitirilmektedir. Bu almalar grafen oksit (GO)/polilaktik asit…
Conventional techniques for wear debris extraction from used lubricants for predictive maintenance such as Ferrography and Filtergram can no longer be employed effectively, as per International Organization for Standardization (ISO 18436) especially in field lubricant analysis. This research aims to develop the solid…
Abstract Known methods for assessing the crack resistance of very hard or strengthened surface layers of materials by using a pyramid indenter are intended for the cases of the formation of radial cracks around the indent. However, at indentation of a pyramid into some types of hardening coatings, for example, made of…
There is a need for an inspection frequency that demonstrates reasonable assurance that the confinement function of dual-purpose-canisters (DPCs) is maintained as these DPCs are returned to storage service following transportation. The DPCs contain spent fuel from shutdown reactor sites. The currently-proposed 100% DP…
The first-, second- and third-order nonlinear optical properties of N-(6-hydroxyhexyl)-5-nitroazophenyl carbazole in gas phase employing sum-over-states (SOS) method have been calculated for the first time. The ground state molecular structure of N-(6-hydroxyhexyl)-5-nitroazophenyl carbazole was obtained by the geomet…
A mass spectrometric study of praseodymium tris(pivaloyltrifluoroacetone) is reported. The mass spectrum of the compound changes as a result of oligomerization as compared to the spectra of metal tris(β- diketonates). The mass spectrum demonstrates signals of mono-, bis-, and triscations with partially destructed liga…
Abstract The compensation ferrometer is an instrument for the measurement of open specimen soft magnetic materials parameters at AC magnetization based on the magnetomotive force compensation method. New magnetizing process regulator that controls voltage induced in measuring winding (magnetic flux density waveform) a…
In this work, effect of coating time on the structural, compositional and morphological properties of MoO3-coated Al2O3 plate for application as an electrode material for ultracapacitor was investigated. The 1[Formula: see text]cm [Formula: see text] 1[Formula: see text]cm aluminum plate was anodized by an electrochem…
Two approaches for improving the resolution via electron probe X-ray spectral microanalysis (EPXRSMA) are considered for the characterization of the nanoparticle composition. The first approach implies the use of L and M series as the analytical ultrasoft X-ray lines of the characteristic radiation of elements to be d…
The article considers the reliability of the bunkering process of ships, as a property of a technical object to save all parameters, which characterize the ability to perform the required functions in the given modes and conditions of use, maintenance, storage and transportation. The description of properties of relia…
Abstract The results of numerical molecular dynamics simulation of the synthesis and fracture of a Ti–Al intermetallic nanocrystal under uniaxial tension are reported. It is shown that, at temperatures higher than 1000 K, fracture is preceded by the phase transition of a nanocrystal from the crystalline to amorphous s…
Background Oil and oil product spills cause significant economic losses and damage to the environment. The increase in the number of accidents in the production, transportation, storage and use of fuel for its intended purpose necessitates the development and implementation of leakage detection systems. The efficiency…
Abstract The frontier of the electron probe X-ray spectral method in the determination of trace metal quantities on a silicon substrate is studied. The experimental data are acquired for ultrathin chromium films on a silicon substrate. It is shown that the signal-to-noise ratio significantly increases at a noticeable…
Del 23 al 27 de Julio de 2018 tuvo lugar en Jaca (Huesca) el curso internacional de verano “Nanomateriales a base de carbón y próximos en estructura: Síntesis, caracterización y estudio de propiedades” que ha sido dirigido por el Dr. Raúl Arenal (INA-LMA-Universidad de Zaragoza) y por el Dr. Wolfgang Maser (Instituto…
Abstract To improve the efficiency of electric motors, we developed the excitation inner core method to evaluate the magnetic properties such as the iron loss of the actual stator core. After preparing two stator cores with a frame, we examined the frames influence of compressive stress by applying the standard and sm…
Study of geothermal energy sources located at depth, as well as the construction of deep deposit for final radioactive waste disposal requires special attention with regard to geological and geophysical research methods, because the search and construction of the facilities are conducted according to the requirements…
