Summary form only given. The reactions have been accompanied ultraviolet (UV) radiation and electron impact with discharge plasmas in water-gas mixture, which can generate oxides such as ozone (O3), hydrogen peroxide (H2O2) and nitrogen oxides (NOx). Two plasma processing systems were established by means of a dielect…
Summary form only given. An atmospheric pressure plasma reactor is used to generate a superhydrophobic surface using nitrogen as the ionization gas and hexamethyldisiloxane (HMDSO) as the monomer. A total of 14 different flow rates ranging from 3 gr/h to 70 gr/h are chosen for plasma polymerization in order to study t…
In this work, the results of theoretical and experimental study of eigen waves of periodical system formed of planar dielectric waveguide and grating are presented. The research revealed the dispersion characteristic features that helps to understand the resonant effects which occur during the radiation forming. Moreo…
This paper represents the results of the research of electromagnetic response of composite radiomaterials containing glass-coated magnetic microwires of different diameters. The frequency dependence of the composite metal reflectance in the range from 10 MHz to 18 GHz is studied. The paper shows that the obtained samp…
Όπως στην περίπτωση του ανθρώπου έτσι και στην περίπτωση των δακτύλων ενός ρομποτικού χεριού, η κίνηση μέσω κύλισης των ακροδακτύλων είναι καθοριστική για την επίτευξη της ευσταθούς σύλληψης και του ομαλού χειρισμού ενός αντικειμένου από το ρομποτικό χέρι. Σε αντίθεση με μια κίνηση ολίσθησης πάνω στην επιφάνεια με την…
We address surface and volume resonance in two concentric cylindrical graphene shells driven by the H-polarized plane wave of the THz range. Modeling implies analytical solution of the wave scattering in presence of impedance boundary conditions at thin graphene shells. Cases are considered of graphene positioned in t…
The developed spectral method of real-time monitoring the growth mechanism of gold nanorods is demonstrated.
The electrical behavior of transformer oil subjected to high electric-field and the possible breakdown phenomena is of great practical interest, since this dielectric liquid has been widely used in high-voltage power apparatus and pulse power systems. Compared with the discharge mechanisms and behaviors derived from v…
While some progress has been made lately in developing transplantation therapy against acute myeloid leukemia (AML), it remains a problematic and aggressive disease, associated with both poor survival, as well as treatments with high toxicity. The field of nanomedicine is however aiming to improve treatment therapies…
Displacement Talbot Lithography is shown to have the resolution capability required for fabricating sub-250nm-period grating structures required in distributed feedback lasers and distributed Bragg reflector lasers, as well as enabling gratings with different periods to be simultaneously exposed using a relatively low…
The study considers the problem of high positional density micro hole forming in chromium-nickel steel by nanosecond laser emission.The article describes the sequence of technological approaches and operations.We modelled the effect of laser emission on the surface of chromium-nickel steel.We created heat field distri…
Summary form only given. A plasma metasurface that works as a tunable THz wave reflector was designed, generated, and experimentally characterized. Theoretical calculations based on the Lewin effective medium model were used to determine the required plasma properties and corresponding reflection bands1. The laser-ind…
In the field of the electrical installation protection, and more particularly for high voltage circuit breakers, one of the most important challenges is to find new gases to replace SF6and reduce the greenhouse effects. Among the several candidates such as CO2, air, vacuum or g31, the recent studies on CF3I highlight…
This paper tries to analyze the Effectiveness and limitations of Chinas ethnic policy about Xinjiang ethnic problems by the economic approach. Recently, China is expected to overcome the domestic problems face challenges it is facing and it hopes to solve problems in Xinjiang, the so called ‘powder keg of China’. ‘One…
Results of simulation of the electron spin resonance absorption peak shape for the magnetic nanopowder are presented. The influence of the magnetic particle diameter on the shape and on the width of the resonance peak is shown. Simulation results show a good agreement with the experimental data of the electron spin re…
The purpose of this analysis is for completion of FPE 596 Culminating Experience in Fire Protection Engineering course in the Fire Protection Engineering Program at California Polytechnic State University. This analysis has been compiled using previous design courses evaluating the egress analysis, suppression design,…
Investigation of the THz radiation propagation in hyperbolic graphene-semiconductor metamaterial is presented. Anisotropy of the hyperbolic media slab was taken into account. The 4×4 Berreman matrix method was adopted for arbitrary orientation of optical axis according to slab boundary.
The objective of this paper is to develop a new identification algorithm for the disturbance currents through the combination of a multi-variable filter (MVF) with the theory of instantaneous powers (PQ-MVF). The MVF exploits the transform of Concordia and ensures the selective or global extraction of harmonic current…
Scattering parameters of a slotted diaphragm in a rectangular waveguide are studied. The transverse slot in the diaphragm is partially filled with dielectric. The mathematical model includes accounting several spatial harmonics for description the electrical field in the slot. Resonance wavelength dependence on geomet…
The components’ content of foams, based on thermoplastic/thermoset blends, was studied by reaction extrusion method. For this purpose, a co-rotating twin screw extruder was designed and assembled. A high pressure-high temperature vessel was used in which the pressure could be dropped quickly. The foaming was carried o…
