The multilayer coating for high gradients is reviewed. Not only the S-I-S structure, but also the S-S bilayer structure are also treated. This is an incomplete manuscript of an invited article which will be submitted to a journal. I have uploaded this version in order to help the understanding on my talk at the TESLA…
With first principles calculations, we predict a novel stable 2D layered structure for group VI elements Se and Te that we call square selenene and square tellurene, respectively. They have chair-like buckled structures similar to other layered materials such as silicene and germanene but with a square unit cell rathe…
We show that a nanoparticle with a “giant” polarizability (i.e., with the polarizability volume significantly exceeding the particle volume) placed in the vicinity of a surface experiences a strongly increased van der Waals force at distances comparable or smaller than the characteristic scale . At distances close R0,…
The use of coal sources of energy has produce fly ashes, which has became a big source of pollution. Fly ash is a fine glass like powder recovered from gases created by coal fired electrical power generation. One of the alternatives to solve this problem is by using this material to produce paving block. This research…
Gold catalysts can exhibit a very high low-temperature activity for the oxidation of carbon monoxide and can be selective in the presence of hydrogen. This paper aims to discuss the prospects for gold-based catalysts to operate in autocatalyst exhaust treatment systems by reviewing very recent results which suggest th…
Values of the current passed through different rectangular windows of the object and angular collimators and measured by Faraday cup with integrator. Obtained beam current distribution was fitted to the Gaussian for determination of its brightness distribution parameters.

Force with over twenty years of R&D experience with numerous aerospace vehicles to include aircraft and rocket systems. In addition, he has performed advanced materials characterization while in the military and at Lawrence Livermore
Critical current density on the electromigration failure is a commonly observed phenomenon in the integrated circuit (IC) interconnect. The critical current density is important for the lognormal distribution and failure time extrapolation of IC metal conductors. In this paper, we report the critical current density (…
Electrically detected magnetic resonance (EDMR) spectroscopy is employed to study the influence of triplet excitons on the photocurrent in state-of-the-art microcrystalline silicon thin-film solar cells. These triplet excitons are used as sensitive spin probes for the investigation of their electronic and nuclear envi…
This report provides a brief review of the 20th annual meeting of the German Language Branch of the Society of Environmental Toxicology and Chemistry (SETAC GLB) held from September 7th to 10th 2015 at ETH (Swiss Technical University) in Zurich, Switzerland. The event was chaired by Inge Werner, Director of the Swiss…
In this paper, we propose and demonstrate a novel guided-mode resonant filter based on a metallic grating sandwiched between two dielectric layers for TE polarization. A theoretical model based on rigorous coupled wave analysis has been developed. The transmission spectra of the grating-based structure show a high tra…
The paper presents results of studying structural properties inherent to chalcogenide glasses doped with manganese. Investigations of the structure were carried out using Raman spectroscopy and X-ray diffraction. The function of radial distribution of atomic density and Raman spectra have been obtained and analyzed.
Abstract The front cover artwork for Issue 13/2016 is provided by researchers from the Catalysis Engineering group, Chemical Engineering Department, Delft University of Technology (The Netherlands). The image shows the formation of covalent triazine framework (CTF) based spheres by using commercially available polyimi…
Sundry brands of same dosage forms are available in the Indian market with the common assertion that they are all bioequivalent. The main objective of the present study was to conduct the comparative dissolution studies of different brands of same dosage forms to determine whether all the formulations used were bioequ…
Nano-size Ag-N co-doped ZnO-CuO composites have been synthesized and tested for their photo-catalytic activity towards degradation of methyl orange in aqueous solution under visible as well as UV radiations. Crystal structure, surface functional groups, metallic composition and band structure of as-synthesized nano-ma…
In our recent work, a side-vent-channel blast-mitigation concept/solution for light tactical vehicles was proposed. As a part of this solution, side-vent channels are attached to the V-shaped vehicle underbody, in order to promote venting of the soil ejecta and gaseous detonation products and, in turn, generate a down…
Abstract The structural and magnetic properties of Si(100)/MgO/Co2Fe0.4Mn0.6Si (CFMS) Heusler alloy thin films were systematically investigated. Highly B2-ordered CFMS Heusler films with an ordering parameter of ca. 70–80% were obtained by both the insertion of a very thin Mg layer into the Si/MgO interfaces to preven…
Increasing the hardness of materials used in machines can lead to a longer useful life while decreasing maintenance downtime. However, high hardness usually results in an increase in brittleness of the material, which can be avoided by surface treatments, such as thermal spray coatings that are largely used to produce…
Methylammonium lead trihalide perovskites have become the harbinger in solar cells lately. However, many fundamental mechanisms, especially those related to the used materials, still need a deeper understanding, in order to further improve the cells’ stability and efficiency. This work discussed the influence of chlor…
