Rare gas microplasmas confined in one dimension to ; 400 torr is introduced to the channel. The requirement for Penning gas mixtures in the narrowest channel appears to be associated with an accelerated electron loss rate.
Transition metal ions doped indium oxide nanomaterials were potentially used as a kind of diluted magnetic semiconductors in transparent spintronic devices. In this paper, the influences of Ni2+ doped contents and rhombohedral or cubic crystalline structures of indium oxide on magnetic properties were investigated. We…
Abstract A mono‐azetidine compound had been demonstrating a ring opening reaction with carboxylic acid (e.g., trimethylacetic acid, TMAA) and that resulted in an amino ester bond formation at ambient temperature. A triazetidine compound (trimethylolpropane tris(1‐azetidinyl)propionate, TMPTA‐AZT) was obtained via Mich…
With the growth in interest in graphene, controlled nanoscale device geometries with complex form factors are now being studied and characterized. There is a growing need to understand new techniques to handle efficient electronic transport calculations for these systems. We present an algorithm that dramatically redu…
Time-resolved x-ray magnetic circular dichroism was used to investigate epitaxial MgO(100)/Co 2 Cr 0.6 Fe 0.4 Al and MgO(100)/Co 2 Cr 0.6 Fe 0.4 Al/Cr/CoFe films. The precessional motion of the individual sublattice magnetization, excited by continuous microwave excitation in the range 2–10 GHz, was detected by tuning…
Evolutions of domain morphology in the ferroelectric thin film subjected to the oxidizing atmosphere were predicted by using the phase field simulations, which incorporate the long-range electrostatic interactions and ionic surface charges. Due to effect of the oxidizing atmosphere, it is found that the ionic surface…
Abstract Silicon alkoxides sol-gel pre-treatments act as coupling agents between metal substrates and organic coatings. This kind of metal finishing is widely studied pre-treatment, but relatively little study is done on the effect of this sol-gel pre-treatment on the durability and on the corrosion protection propert…
Using a hydrochemical simulation, temperature dependency of single-bubble sonoluminescence (SL) in a concentrated solution of sulfuric acid has theoretically been studied. With calculating the phase diagrams of an SL bubble in the solution of 85% acid, maximum acquirable SL emissions at different ambient temperatures…
Micro-tubular solid oxide fuel cells (MT-SOFCs) are a much smaller version of larger tubular SOFCs. They are operational within seconds and allow a higher power density per volume than the larger version. Hence they are a potential technology for automotive, auxiliary and small scale power supply devices. In this stud…
The dependence with Ga content ( x ) of structural, magnetic, and hyperfine properties of Ga x Fe 4– x N compounds has been studied using the full-potential linearized augmented planewave method based on density functional theory. A nonlinear increase of the lattice parameter with x was observed, ascribed to the diffe…
An Sb-rich (48 at.%) Si-Sb-Te phase-change material with moderate Si content (24 at.%) is proposed for phase-change random access memory (PCRAM) applications. The real time amorphous to crystalline transformation was studied by in situ transmission electron microscopy observations and in situ resistance measurements.…
Extensive computational investigations along with additional quasielastic neutron scattering data were used to obtain a consistent picture of the extensive fluxionality of hydride and dihydrogen ligands in Fe(H)(2)(H(2))(PEtPh(2))(3) over a wide range of temperatures from 1.5 to 320 K. We were able to identify three d…
Optical trapping and driving of small objects has become a topic of increasing interest in multidisciplinary sciences. We propose to use a chain made of metallic nanoparticles as a resonant light sail, attached by one end point to a transparent object and propelling it by the use of electromagnetic radiation. Driving…
The evolution of hydrolyzed alkoxide–carboxylate sol–gel precursor solutions of barium titanate was investigated by time-resolved small-angle X-ray scattering (SAXS) and viscosity measurements. Sols were prepared from titanium(IV) iso -propoxide in 2-methoxyethanol and barium acetate in acetic acid. Analysis of the ex…
Batch adsorption studies were conducted to remove cutting oil from wastewater using activated lemon (species Citrus x limon) peels. The effect of various important parameters, namely, pH, dose of adsorbent, contact time, mixing speed, and initial oil concentration, and their optimum conditions for maximum sorption eff…
We provide nanoscale evidence of the role of sheath exopolymers in the silicification of the sheathed cyanobacteria Calothrix. Electron microscope observations of silicified Calothrix cells revealed that silica accretes directly onto EPS sheath fibrils to produce an open web of silica particles that could remain perme…
Abstract The rheology/morphology relationship of plasticized and nonplasticized ethylene–propylene–diene–terpolymer/polypropylene (EPDM/PP) TPOs was studied. The aim was to investigate the effect of a plasticizer on the morphology, specially on the co‐continuity interval of these blends. The addition of a plasticizer…
We investigated the effect of charged domain boundaries (CDBs) on the coercive voltage (Vc) in polycrystalline Pb(Zr0.25Ti0.75)O3 (PZT) thin films using angle-resolved piezoresponse force microscopy (AR-PFM). By using the AR-PFM technique, we could observe the detailed domain structure with various degrees of CDBs inc…
A series of nickel(II) complexes of a 2,6-dihydroxynaphtho-1-aldehyde Schiff base was synthesized. By means of in situ formation of metal-containing tectons, some of those complexes afforded sub-millimeter-scale single crystals directly from the reaction mixture. The complexes consisted in part of various ladder-like…
Abstract BACKGROUND: The poly(3‐hydroxybutyrate)—P(3HB)—is a polyester synthesized by many bacteria and stored as an energy reserve material in the cell cytoplasm as water‐insoluble inclusions. The aim of this research was to present a mathematical modeling approach in order to describe the culture kinetics of the bac…
