The energy shift of the line resulting from the decay of the (2p53s2)2P3/2 lowest autoionizing state in Na atoms has been measured in the ejected-electron spectra obtained at near-threshold electron impact energies. Contrary to the smooth asymptotic behavior predicted by the known models of the PCI effect, the data re…
Abstract The frequency‐dependent hyperpolarizabilities of chelidamic acid complexes Mm(C7H3O5N)n (MCu, Ag) were investigated under the time dependent density functional theory (TDDFT) combined with the sum‐over‐states method (SOS). The relationship between molecular orbitals and nonlinear optical (NLO) properties has…
Positioning of charged nanoparticles with the help of charge patterns in an insulator substrate is a known method. However, the creation of charge patterns with a scanning electron microscope for this is relatively new. Here a scanning electron microscope is used for the creation of localized charge patterns in an ins…
This article presents a multiple-electron-beam imaging technique, which is able to simultaneously process images from multiple scanning sources. The proposal is based on the detection of wide-angle BSEs, whose spectrum is predicted to be largely confined to a sharp elastic peak at the primary electron beam energy, whi…
Abstract Along the steel industry history, the production of flat‐steel products has technologically evolved towards reducing slab thickness at the output of the continuous casting machine. This development has been related to the incessant requirement of providing a certain steel quality at lower costs. As a result o…
We report measured absolute single and multiple charge-exchange cross sections for Fe q + ions colliding with CO, CO 2 and H 2 O. A retarding-field method is used in two different approaches for charge-state analysis of the ion beam after traversing the stationary target gas cell. The projectile energy is 7 q keV. Thi…
This paper investigates the plasmon modes (TM01polarized modes) in a step-index optical fiber coated by a thin metallic film, surrounded by a dielectric regions. This original Plasmon-modes modeling considers the core and cladding layers of the fiber as analysis components. The dispersion curves of the structure with…
Ultrafine grained materials prepared by methods of severe plastic deformation appear to show good ductility for their high strength. To a large extent this ductility enhancement, for the given strength, is shown to correspond to the fracture ductility and not the uniform ductility at maximum stress. The improved fract…
A procedure was developed for preparing polymeric materials with grafted luminescence organosiloxane coatings containing conjugates of rare-earth elements with various color spectra.
540 female were measured by using photo and manual measuring methods. Among these people there are 317 young and 223 elder. By using the Matlab program, female's frontal and sided pictures were extracted and the outlines were got, from which the relevant height, thickness and width values could be drawn. Then construc…
Phased rectifier thyristor commutate circuit has brought serious harmonic pollution to electric power grid. In this paper, a novel power filter method is proposed to solve an actual harmonic problem of a steel factory which was brought by phased rectifier thyristor commutate circuit in ZheJiang province of China. This…
We successfully prepared the surface photovoltage sensor system using several types of modified mesoporous silica as a sensitive materials. The sensitive materials were fabricated using self-ordered and structure-controlled modified mesoporous thin films, which is synthesized by a molecule surfactant method using spin…
We investigated the basic properties of Mn-Zn ferrite thin films fabricated by pulsed laser deposition (PLD) for the purpose of controlling their saturation magnetizations ( M s ) and electrical resistivities. The M s and the electrical resistivities of fabricated samples varied with their compositions and the post-an…
In the case that a self-organized diblock copolymer pattern is applied as an etching mask, one of the polymer components is required to have a high etching durability similar to that of silicon oxide. One suitable material for the purpose is a mixture of polystyrene-b-polyethyleneoxide (PS-PEO) and silsesquioxane (SSQ…
This study focuses on grain motion in TZP (Tetragonal Zirconia Polycrystal) ceramics during superplastic deformation. The specimen was 16 times elongated repeatedly at 1400°C in air. The increment of true plastic strain was set to be 2%, and the specimen was deformed up to 30.3% true plastic strain finally. After each…
The effect of deposition temperature on the electrical, optical, structural, and morphological properties of indium doped zinc oxide thin films, ZnO:In, deposited by the chemical spray technique have been studied in this work. The starting solution was prepared using zinc pentanedionate and indium chloride as Zn and I…
Computer simulation was performed for the processes occurring in the basic elements of the cathode (active layer, gas-diffusion layer) and bipolar plate of a fuel cell with Nafion as electrolyte and a platinum catalyst. Current generation in the active layer was considered together with the heat exchange processes (re…
The Debye-Waller factors obtained by EXAFS analysis of the Te nanoparticles are analyzed by a Einstein model. The Einstein temperatures for the intra- and interchain interactions are depend on the size of the Te nanoparticles. With decreasing the size of the Te nanoparticles the Einstein temperature for the intrachain…
This work deals with investigations on generalised scattering parameters of heavy open-shell metal atoms. Electron-atom collisions with heavy open-shell targets are influenced by spin-orbit and exchange effects simultaneously. Experimental results for the asymmetry function S A and the exchange parameter T y of Lead (…
Controlling reflection of electrons from an array of electrodes is a key feature of an electron lithography system currently under development. Here the authors describe a technique for characterizing this control. The apparatus is only 30mm long, features simple colinear electron optics and a photocathode that emits…
