The work presents results of a study of the electromagnetic properties Li-Zn ferrite ceramics in a wide frequency range. It is shown that a homogeneous composition of such ceramics typically appear good radio-absorbing properties in the low-frequency range of microwave. The method of solid-phase radiation-thermal synt…
Abstract Hollow silver particles with three different shapes, i. e., spherical, cylindrical, and octahedral, were used as raw material to produce open-cell silver foams. The shape difference of the particles resulted from the reduction of different shaped silver sulfates. Fabrication of silver foams was carried out us…
Using the first-principles technique, we systematically investigate the elastic, electronic, mechanical and optical properties of Al 3 BC 3 . The calculated structural parameters of Al 3 BC 3 are in agreement with the experimental results. Electronic structure calculations indicate that Al 3 BC 3 has a larger indirect…
Co/Pd bi metallic catalyst supported on MgO has been prepared by sol gel method, at different calcination temperatures of 250 and 550 C. They were introduced in to the reactor for 5 hrs of reaction. The CNTs were collected. The obtained CNTs were characterized by XRD and SEM and the yield was observed. It has been con…
Despite the theory of electromigration is well understood, it is still none trivial to meet all the qualification requirements as technology scales. This paper addresses the impacts of via configuration on electromigration from both physical and statistical point of view.
The effect of impact compression on age hardening behavior was examined for Meso20 and 6061 aluminum alloys using a single stage gun. The hardness of Meso20 and 6061 aluminum alloy applied with an impact compression (about 5.0GPa) after the solution treatment increased with the aging time. The cluster of point defects…
Space charge behavior of XLPE/SiO2nanocomposites with nanoparticle surface modification via titanate(TC) and vinylsilance(VI) coupling agents was investigated. SEM results clearly show that TC and VI coupling agents improved nanoparticle dispersion within XLPE matrix due to the increasing surface hydrophobicity of SiO…
Electrospinning represents a simple and convenient method for generating polymer fibers has been widely applied to produce porous nanofibers. The PLA fibers obtained in this research showed a significant nanoporous surface by varying solvent compositions of chloroform (CF) and N,N-dimethylformamide (DMF).The nanopores…
Abstract We have developed an achromatic polarizer using novel dichroic pigments. We established a method to control the light absorption, dichroic ratio, and alignment direction of pigments and successfully developed a low power monochrome‐type reflective liquid crystal display with high reflectivity, paper white and…
Ultra-thin two-dimensional materials are the recipient of high expectations by both research community and Industry, for their intrinsic electrical properties to be exploited in device applications. While it is nowadays clear that bare graphene will not manage to comply with ITRS [1] requirements for beyond-CMOS devic…
Traditional denim made by using 100% cotton and novel denim made by using cotton in warp and spun PP in the weft were treated in 11 different ways on industrial garment washing machines with the help of various textile auxiliaries and pumice. There is an obvious change in color of denim. This change was measured by us…
Improved recyclability and cost pressure encourage the use of thermoplastics as electrical insulation material for demanding electrical applications. Besides their basic mechanical, thermal and electrical properties it is of interest to study the aging behavior of these thermoplastic materials. In this paper a non-sta…
Technology scaling has led to severe degradation of EM performance for advanced interconnects. On one hand, the median time to failure becomes shorter due to the reduction of critical void size and the increase of the Cu mass flow rate. On the other hand the variability increase has led to broader failure time distrib…
Hafnium carbide powder was synthesized by sol-gel polycondensation of hafnium chloride with citric acid. The starting materials were dissolved in water and mixed homogeneously on a hot plate until a precomposite gel was formed. Pyrolysis of the obtained gel resulted in formation of monoclinic hafnia and amorphous carb…
The effect of strain rate up to nearly = 102/s on the tensile stress-strain properties of isotropic fine-grained nuclear-grade graphite IG-11 was investigated. Cylindrical tensile specimens machined out of graphite bars were used in both static and dynamic tests. The dynamic tensile stress-strain curves up to fracture…
Heterogeneous equilibria in the manganese-carbamide-sulfuric acid-water quaternary system at 25°C are studied using the solubility method. The concentration boundaries are determined for crystallization of the initial solid components, eutectic compositions of the ternary systems, and binary compounds formed in the ca…
In this work, surface activation of automotive polymers using atmospheric pressure plasmas was investigated. The aim was to increase the polar fraction of the surface energy of both plane and convex polymer devices with a radius in the range of 30 mm. For this purpose, a fittable low temperature atmospheric pressure p…
Conventional power plants for the conversion of fossil fuels to electricity have low efficiencies and produce large amount of carbon dioxide, a greenhouse gas, which contribute to climate change. Hence, a molten tin reformer and methane-fuelled SOFC with molten tin anode (Sn(l)-SOFC) for easier CO2 capture and higher…
Aluminum alloys have extensive applications in engineering structures like aircraft due to their high strength-to-weight ratio. However, these alloys are very reactive and prone to corrosion attack. Paddy waste is one of the beneficial natural sources that have a potential contribution on inhibiting the corrosion atta…
The microstructure of samples of cladding tubes made of steel 0.07C-16Cr-19Ni-2Mo-2Mn-Ti-Si-V-P-B (EK164) irradiated to different damaging doses (up to 77 dpa) in the BN-600 reactor at temperatures from 440 to 600°C has been investigated. Characteristics of radiation porosity formed during irradiation in different tem…
