In this work, we report the photoactivity of BaSnO3 in the photoreduction of methylviologen and the effect of quantum dot sensitization by covalently linking CdTe/CdS core/shell quantum dots in the surface of BaSnO3.
The crystallization behavior a High Chromium Cast Steel (HCCS) has been determined under Equilibrium conditions with ThermoCalc® software, and under non-Equilibrium conditions through Differential Thermal Analyses (DTA). The results are compared to each other and the differences between the predicted solidification pa…
Turbulent flow and heat transfer characteristics of textile machine are numerically investigated. To examine the influence of flow structures on the drying performance of fabrics, the nozzle shape of high temperature chamber is changed. For several nozzles, flow and heat transfer characteristics are discussed. The res…
Plasmonic materials and metamaterials have been widely utilized to achieve spectral transmission, reflection and absorption filters based on localized or delocalized resonances arising from the interaction of photons with nanoscale patterns. However, the realization of visible-frequency, high-performance, large-area,…
The paper presents a mathematical base modeling combined to Modified-Winding -Function-Approach (MWFA) for eccentricity fault detection of a round-rotor synchronous machine. For this aim, a 6-pole machine is considered, and the machine inductances are computed by MWFA in healthy and also under eccentricity fault. A nu…
The relevance of the cavity expansion analyses to the penetration mechanics of rigid projectiles, impacting metallic and concrete targets, is discussed. In the past six years we offered an alternative approach to that reviewed by Sobeski and Urgessa (2015), and we briefly discuss that work in this comment. To our best…
Abstract Photoaligned ferroelectric liquid crystals are described. The new electrooptical modes as well as their new applications in displays and photonics are highlighted. Electrically suppressed helix (ESH) mode was considered as the most promising one.
An ideal hyperbolic metamaterial (HMM), which has a perfect hyperbolic dispersion curve, theoretically can support modes with indefinite wavenumbers, leading to large photon local density of states (LDOS) and many applications such as enhancing light-matter interactions, spontaneous emission and thermal radiation. Her…
Abstract In the current paper, we compare the effect of different hydrogen halide acid agent systems in chemical reduction of graphene oxide (GO) thin layers. We observe the large iodine ion can facilitate the reduction reaction in comparison with bromide and chloride counterpart ions. We show the sheet resistance of…
This thesis investigates the synthesis and activation of highly monodisperse Au25(SR)18 - clusters and bimetallic clusters (AuAg and AuPd) protected with various stabilizers for reduction and hydrogenation catalytic reactions. The first chapter is the introduction chapter, which summarizes the literature involving mon…
Cu nanoparticles decorated CVD growth single layer and 2-3 layers graphene films have been synthesized by sputtering deposition and annealing process. The wrinkles were observed on single layer graphene due to high annealing temperature (700 degrees C) and rapid cooling process, which were proved by HRSEM and Raman sp…
Abstract : This research is part of an ongoing program of study focused on dielectric materials based on a novel hypothesis: that porous electrically insulating solids in which the pores are filled with liquids containing an ionic species (such as water with dissolved salt) will have very high dielectric values by vir…
Chalcogenide phase-change media provide a uniquely flexible platform for both nanostructured and optically-rewritable all-dielectric metamaterials. Non-volatile, laser-induced phase transitions enable resonance switching in nanostructured chalcogenide meta-surfaces and allow for reversible direct-writing of arbitrary…
New nanocomposites, poly(diphenylamine-co-3-aminobenzonitrile)/palladium (P(DPA-co-3ABN)/Pd) and poly(diphenylamine)/palladium (PDPA/Pd), have been prepared by pulse potentiostatic method and used as electrocatalysts for borohydride oxidation. Linear sweep voltammogram of P(DPA-co-3ABN)/Pd-ME exhibited the oxidation w…
The diffusion and surface effects of several fission product elements implanted in SiC have been investigated. SiC is used as the main barrier for fission products in modern high temperature gas cooled reactors. An understanding of the transport behaviour of the implanted ions and their interactions with SiC will shed…
This thesis uses systems engineering principles and an evolutionary process model to develop a parts harvesting procedure for the Mine Countermeasure (MCM-1) class ships. This procedure will facilitate harvesting required components from a decommissioning MCM-1 class ship that will be refurbished for reuse on the rema…
Abstract : Numerical simulations of ballistic impact and penetration by tungsten rods into targets consisting of layers of aluminum nitride ceramic tile(s), polymer laminae, and aluminum backing are conducted over a range of impact velocities on the order of 1.0 to 1.2 km/s. Results for ballistic efficiency are compar…
Photoinduced defects in a -Si:H films arise due to an increase in the density of midgap states when weak strained silicon–hydrogen (Si–H) bonds transform to dangling Si—Si bonds and also due to the presence of separate regions with different densities and types of Si—H bonds. In rare-earth-doped InGaN/GaN multiple qua…
Pseudogap is a unique property of high-[Formula: see text] superconductors. However, it was also found that there is a similar pseudogap in giant magnetoresistive La–Sr–Mn–O materials, which are not superconductors. In our previous research, we suggested that the origin of the pseudogap is correlated with the stabilit…
Splitting of reflections from boron carbide has been found for the first time by an X-ray diffraction study of polycrystalline mixture of boron carbide В15–х С х , (1.5 ≤ x ≤ 3) and its magnesium derivative C4B25Mg1.42. An analysis of reflection profiles shows that this splitting is due to the presence of boron carbid…
