A novel Frequency Selective Surface (FSS) is proposed for the design of polarization-insensitive metamaterial absorbers that operate below 1 GHz, where the first resonances of small commercial enclosures take place. The novel FSS shows a strong sub-wavelength response, enhanced by the dielectric substrate, which allow…
In the present study, the series of PP/SiC composites, containing 5, 10, 15, 20 and 30 wt% of waste SiC particles from abrasive industry, were prepared in order to obtain composites with superior mechanical properties. PP/SiC composites with appropriate amount of SiC were used in order to study the effect of polypropy…
In this study, poly (glycerol sebacate) (PGS) was initially synthesized via condensation polymerization of glycerol and sebacic acid at equimolar ratio (1:1) at 130°C for 24 h. The number average molecular weight (Mn) of the resulting polymer determined by gel permeation chromatography (GPC) was about 2800 g/mol. Poro…
Currently, FPGAs serve as Field-Programmable-Systems-on-Chip (FPSoCs) and are widely used to implement computationally intensive real world applications. As the number of components in FPSoCs increase, the interconnect schemes based on Network-on-Chip (NoC) approach are increasingly being used to overcome the deficien…
ZnO nanowires deposited on Si substrates were prepared by thermal evaporation of a mixture of ZnO and carbon powder. Ag ions with an energy of 63 keV and a dose of 5 × 10 15 ions/cm 2 were implanted into the as-prepared ZnO nanowires. After ion implantation, the Ag-implanted ZnO nanowires were annealed in air at diffe…
The port-based plasma diagnostic infrastructure on ITER is described, including the port plugs, the interspace support structure and port cell structure. These systems are modular in nature with standardized dimensions. The design of the equatorial and upper port plugs and their modules is discussed, as well as the do…
Abstract Intensive quenching (IQ) is an alternative method of hardening steel parts, providing extremely high cooling rates within the martensite-phase formation temperature range. This article begins with the description on the general correlation between steel mechanical properties and cooling rate during IQ. It pre…
Abstract The use of renewable energy has grown strongly in all end-use sectors such as power, heat, and transport. This article describes thermal spray applications that improve efficiency, lower maintenance costs, and prolong operational life in the renewable energy technologies, including wind power, hydro power, bi…
Abstract Carburization is the process of intentionally increasing the carbon content of a steel surface so that a hardened case can be produced by martensitic transformation during quenching. Like carburizing, carbonitriding involves heating above the upper critical temperature to austenitize the steel. This article i…
We model a loss of flow accident (LOFA) in the ARIES-ACT1 tokamak design. ARIES-ACT1 features an advanced SiC blanket with LiPb as coolant and breeder, a helium cooled steel structural ring and tungsten divertors, a thin-walled, helium cooled vacuum vessel, and a room temperature water-cooled shield outside the vacuum…
Extended abstract of a paper presented at Microscopy and Microanalysis 2013 in Indianapolis, Indiana, USA, August 4 – August 8, 2013.
Hydroxypropyl starch (HPS) is synthesized by using maize starch and different concentrations of both propylene oxide )PO) and sodium hydroxide (NaOH) with the intent to obtain HPS products which can better serve as a reducing and stabilizing agent during the preparation of silver nanoparticles. Such a preparation is c…
With the development of nanotechnology, more and more commercial nanoproducts enter our daily life. Therefore, the toxicity of nanomaterials becomes an increasing concern. Recently, great progress has been achieved in this field, which includes in vitro and in vivo experimental studies of the interactions between nano…
The ferromagnetic semiconductor La 2 NiMnO 6 (LNMO) has recently received much attention due to its high Curie temperature ( T C ∼ 280 K), which is close to room temperature. We prepared single-phase LNMO polycrystalline samples and investigated the temperature- and field-dependent magnetic behaviors of bulk LNMO. Bet…
Water-dispersible CdS quantum dots (QDs) were synthesized in a simple one-pot noninjection route. The X-ray diffraction (XRD) pattern of the nanoparticles shows the cubic structure with particle size of the order 5-7 nm which was in good agreement with the transmission electron microscopic (TEM) studies. Selected area…
The wear resistance of a (A 356) Aluminium alloy reinforced with silicon carbide particles was studied as a function of temperature. The tests were performed at three temperatures :5, 18, and 30℃, and at three impact loads: 29.4, 39.2 and 49 N on dray environment. The reductions in the temperature were produced throug…
The study of the aggregation of a steroid-functionalised porphyrin derivative shows the formation of chiral suprastuctures. Kinetic studies indicate that the mechanism of the aggregation strongly depends on both the nature of the media and on the concentration of the tetrapyrrolic macrocycle.
We report an unusual persistence of superconductivity against high magnetic fields in the iron-chalcogenide film FeTe:Ox below ≈ 2.5 K. Instead of saturating, like mean-field behavior with a single order parameter, the measured low-temperature upper critical field increases progressively, suggesting a large supply of…
Summary The phase behavior of isotactic poly(propylene) (i‐PP) and 1,3:2,4‐bis(3,4‐dimethylbenzylidene)sorbitol (DMDBS) was studied by using differential scanning calorimetry (DSC), rheology and optical microscopy and can be characterized by a simple binary monotectic phase diagram. DMDBS is a well‐known nucleating an…
Effect of the cathodic current density, pH value, electrolyte temperature, and concentration of aluminum oxide introduced into the electrolyte on the wear, microhardness, and internal stresses in nickel-cobalt-aluminum oxide composite electrolytic coatings was studied. It is shown that the coatings under consideration…
