Air-sintered SrCoO3 is strongly reduced at 1020°C in PO2 = 1.6 × 10−9 MPa and then post-annealed at various temperatures in air. The conductive and structural characteristics are examined, comparing them with those of air-sintered. Although annealing in a reducing atmosphere breaks down SrCoO3 to several compounds, Sr…
From last decade, iron oxide nanoparticles (IONPs) have been extensively used in a wide variety of biological and medical applications such as contrast agent in magnetic resonance imaging (MRI), in magnetic hyperthermia to cure cancer, drug delivery, cell labeling and so on. However, studies related to their cytotoxic…
Over the last several years there has been a mutually beneficial ongoing technical interchange between the U.K and the U.S. related to various aspects of space radioisotope power systems (RPS). While this interchange has been primarily focused on materials based activities, it has also included some aspects related to…
The item can only be dispensed within artificial tasks that, although useful in the lab, do not reflect the real world. There, the attended item is the goal of search. Hulleman & Olivers' (H&O's) model can ignore the item only by reducing search to the question of whether a patch of 0s (distractors) contains a 1 (targ…
Aluminum-doped zinc oxide (AZO) thin films were successfully prepared on glass substrates at room temperature by DC magnetron sputtering. The sputtering time varied from 5 minute to 30 minute, while the power was kept at 230W for all depositions. The structural and optical properties of AZO films were investigated by…
Fluorophosphates, BaMPO 4 F (M = Cu, Co), with a tunnel structure show different magnetic behaviors, in which BaCuPO 4 F exhibits a paramagnetic behavior down to 2 K, while BaCoPO 4 F undergoes long-range antiferromagnetic ordering at low temperature.
The quantum chemical computations using the density functional theory have been performed in order to investigate linear and nonlinear optical properties of 1, 3-Bis(3, 4-dimethoxyphenyl)prop-2-en-1-one. The NLO response on the electronic structure of the molecule is studied. Energy band gap of the molecule is obtaine…
Cobalt oxide (Co3O4) nanocubes with high crystallinity and a narrow size distribution have been synthesized in one pot process under highly condensed hydrothermal reactions using cobalt(II) nitrate (Co(NO3)2) and sodium hydroxide or tetramethylammonium hydroxide. The particle morphology was controlled to a cubic shape…
In most microfluidic applications, pressure-driven Poiseuille flow in a contained cross-section with no-slip boundary conditions is the underlying fluid-mechanical model. Solutions for this problem exist for many known cross-sections. We have recently demonstrated a simple method to solve the relevant Poisson equation…
We present a novel design procedure for shielded omega-bianisotropic metasurfaces (O-BMSs), fully reflecting a given incident plane wave into a desirable direction, without any spurious scattering. In previous work, we have proven that passive lossless O-BMSs can be designed to support any given field transformation t…
Using differential thermal analysis, X-ray phase analysis, electron microscopy, and optical microscopy, the nucleation of crystals in glass obtained by blending metallurgical slag with silicon dioxide has been studied. The type of crystallization (homogeneous or heterogeneous, volume or surface) is revealed for each o…

The structures and energies of the B and Ga incorporated γ -alumina surface as well as the adsorption of water are investigated using dispersion corrected density functional theory. The results show that the substitution of surface Al atom by B atom is not so favored as Ga atom. The substitution reaction prefers to oc…
In this study, K shell X-ray fluorescence cross-sections (σKα, σKβ and σK), K shell fluorescence yields (ωK) and K to L shell vacancy transfer probabilities (ηKL) of ferromagnetic 3d transition metals (Fe, Co, Ni) were investigated to understand how the relationship between ferromagnetism and these values changes with…
RESUMO Revestimentos metálicos podem ser aplicados para diferentes finalidades, como exemplo, para melhorar as propriedades mecânicas, catalíticas, anticorrosivas ou simplesmente melhorar o aspecto decorativo. Neste trabalho foram obtidas ligas de Ni-Fe pelo processo de eletrodeposição utilizando um banho eletrolítico…
Electrical and mechanical properties of the blend un saturated polyester – poly methyl methacrylate (UPE – PMMA) after consolidation nanoscale zinc oxide in terms of weight percentage have been studied. Mechanical – layup Liquid mixture method to prepare polymer blend coupled with ultrasonic technique to distribution…
In recent years, hybrid nanomaterials of graphene and polyaniline have attracted extensive interest and have been considered as promising electrode materials for supercapacitor combining the advantages of both materials with synergistic effects. In contrast to the well-developed two-dimensional planar structure of gra…
The electrical conductivity of exfoliated graphite in water nanofluids has been experimentally determined, and compared with the same property when the dispersed nanosheets have been oxidized. The effect of oxidation on this property is different if compared with the case of sintered dry nanosheets. In any case, for t…
Reducibilities of wüstite and calcio-wüstite have been examined using high temperature X-ray diffraction analysis including the effect of hydrogen on the reducibility. Fe2O3 reagent powders and hematite ore powders were used for reduction of wüstite (denoted as FeO) and sintered ore powders were used for reduction of…
The optical and electrical properties of Si rich SiC (SRSC) solar cell absorber layers will strongly depend on interfacial layers between the Si and the SiC matrix and in this work, we analyze hitherto undiscovered interfacial layers. The SRSC thin films were deposited using a plasma-enhanced chemical vapor deposition…
