The metal–silicon thin−film system is not isostructural and furthermore exhibits pronounced interdiffusion and chemical reactions. Therefore the growth of metallic films on silicon leads to a high concentration of defects in the film, especially at its substrate interface. The material also contains stress and a trans…
We study decoherence effects due to second order chromaticity for small amplitude kicks, in order to estimate the energy spread from TbT data of the NSLS-II storage ring. The bare lattice case (no Damping Wigglers and Insertion devices) has been considered, due to the long transverse radiation damping time. To minimiz…
Last few years, the perovskite materials have attracted great attention in organic-inorganic solar cells due to their excellent light-harvesting properties, tune-able direct band gap, high molar extinction coefficient, high carrier mobility. This platform makes new opportunities for the development of solution-process…
Composites containing epoxy resin and functionalized multiwall carbon nanotubes with different mass concentrations were preparedby ultrasonic homogenization followed by curing at room temperature.Mechanical characterizations of composites reveal a general improvement of the flexural strength at tensile stress and Youn…
The performance of future accelerators could be limited by electron cloud phenomena and high photodesorption yields. For such a reason, the study of secondary electron and photodesorption yields of vacuum materials is essential. The eradication or mitigation of both secondary electron and molecule desorption could str…
Fueled by two highly enriched uranium-bearing fuel elements surrounded by a large concentric ring of beryllium reflector, the High Flux Isotope Reactor (HFIR) provides one of the highest neutron fluxes in the world and is used to produce unique isotopes like plutonium-238. The National Aeronautics and Space Administra…
Multipacting is a common issue in the context of cathode units of superconducting radiofrequency photoinjectors (SRF-guns) utilized in linear accelerators under resonant conditions. In this study, Titanium Nitride (TiN) and Carbon thin films have been prepared by DC and RF magnetron sputtering in a Nitrogen and Argon…
A combined experimental and theoretical study on the molecular structure and the vibrational spectra of 2-furoyl chloride (2FCL) is reported. The FT-IR and FT-Raman experimental spectra are recorded in the region 4000-450 cm -1 and 4000-50 cm -1 respectively. The molecular geometry and vibrational frequencies are calc…
The aim of this communication is to explore a simple and efficient method for fabrication of superhydrophobic surface by candle smoke particles (CSPs). The properties of CSPs before and after the calcination process has been studied by SEM, TEM, TG-DSC, FT-IR and contact angle measurements. The results show that there…
The framework of this article is the Navier-Stokes-Allen-Cahn system for the dynamics of a fluid whose two phases can transform into each other. It studies traveling waves that describe the internal structure of moving interfaces between the phases. A general result on the existence and bifurcation of these waves is d…
One of the obstacles of using the fuel cells in remote areas is the absence of hydrogen infrastructure to supply the required fuel to the unit. However, this can be solved by producing hydrogen on site from water electrolysis. In this paper, the sizing of a standalone hybrid PV/PEMFC system to supply electric power fo…

In this paper, our interest is focused on a theoretical investigation of chains based on Cd1-xZnxS quantum dots inserted in an insulating material. This system, supposed as a succession of flattened cylindrical quantum dots with a finite barrier height at the boundary, is treated with use a novel potential model. The…
Nonlinear optical properties of Pyronin B dye was studied by zscan technique using Q switched pulsed Nd: YAG laser of wavelength 532nm.The dye was prepared in various concentrations 0.3mM,0.4mM and 0.5mM respectively. The dye exhibited negative nonlinearity and saturation absorption in closed and open aperture zscan m…
A high interest developed over time in the fusion nuclear energy field during the last years, especially in producing functional materials that could withstand high temperatures and nuclear irradiations. Analyses upon the fusion reactor walls were performed sequentially, on specific areas of interest, studying the ero…
The monomeric species of Cr(VI) was found to be kinetically active in the absence of 1,10-phenanthroline (phen) under pseudo-first order conditions, whereas in the 1,10-phenanthroline promoted path, the Cr(VI)-phenanthroline complex undergoes a nucleophilic attack by dimethyl sulfoxide (DMSO) to form a ternary complex…
Microbial fuel cell(MFC) is a promising technology in conversion of waste to energy and also providing green environment.In this paper performance of various carbon electrodes in MFC is categorised based on electricity generated working on MFC in various condition. As a new type of electrodes used in MFC which create…
Silver and Titanium Nanocomposite materials are well known as two materials that can effectively eradicate bacteria. Study on the synthesis and characterization of these materials using Horizontal Vapor Phase Growth (HVPG) technique was introduced to combine between Silver and Titanium in a single synthesis. Silver an…

The work is aimed at obtaining highly efficient one-piece units of gas turbine aircraft engines - disks with blades (blisks). Intermetallic γ΄ + γ alloys based on γ-Ni3Al phase of the VKNA type selected as blade material and Ni-based high alloy EP975 selected for discs have similar initial melting temperatures ( ~ 134…
