Abstract Nitrate (anion) salts with nitroxy‐functionalized ammonium cations were synthesized. Several revealed surprising thermal and hydrolytic stability. Various physical properties were measured, and Gibbs free energy (ΔGr(298)) differences between the salts and postulated products of their thermal decomposition we…
Transformers with parallel windings are commonly used to reduce the losses in the windings. Windings losses depend on the winding positioning and the frequency effects because each winding affects the current sharing of itself and the neighboring windings. In this paper a methodology for determining the connections of…
A novel single-switch cell voltage equalizer using voltage multipliers for series-connected supercapacitors (SCs) is proposed. Since the proposed equalizer can operate with a single switch at a fixed duty cycle when operated in discontinuous conduction mode (DCM), the circuit complexity can be reduced significantly wh…
Abstract The hydrosilylation reaction is very important in silicone‐introducing reactions and in the crosslinking of silicone rubbers. In this study, through Fourier transform infrared spectroscopy, the hydrosilylation reaction between hydrogen‐containing polysiloxane (H‐PDMS) and several kinds of rubber, including st…
Abstract In this work, 2,2′‐methylene‐bis‐(4,6‐di‐t‐butylphenylene)phosphate lithium (NA03) was synthesized and its crystal structural characterization was obtained by single crystal X‐ray diffusion. The crystal data showed geometrically the cell parameter of NA03 matched with isotactic polypropylene (iPP), the a cell…
Abstract Poly[2,2′‐(p‐oxydiphenylene)‐5,5′‐bibenzimidazole] (OPBI) was polymerized in poly(phosphoric acid) (PPA) with the presence of the pristine nanodiamonds (NDs) (0.2–5 wt %) to fabricate NDs‐g‐OPBI/OPBI nanocomposites via Friedel–Crafts (F‐C) reaction. The OPBI chains were successfully attached to the NDs throug…
A new dioxomolybdenum(VI) complex, [MoO2L(CH3OH)]· CH3OH, where L is the dianionic form of N’-[1-(2-hydroxyna- phthyl)ethylidene]-3-methylbenzohydrazide, was prepared and structurally characterized by physicochemical and spectroscopic methods and single crystal X-ray determination. The complex is a mononuclear molybde…
The dendrite growth velocity during non-equilibrium solidification of tetragonal Ni 2 B crystals is measured as a function of undercooling on electrostatically levitated droplets. High-speed video imaging is applied to measure in situ the propagation of the solid-liquid interface apparent on the sample surface. To ana…
Epoxy resin was filled with sawdust to optimize the flexural properties of the composite for structural applications. In order to reduce costs, it will be necessary to fill as much sawdust as possible subject to maintaining sufficient strength of the composites in civil and structural applications. This project varies…
Antimony-doped Tin oxide (ATO) films have been prepared by inkjet-printing method using ATO nanoparticle inks. The electrical and optical properties of the ATO films were investigated in order to understand the effects of rapid thermal annealing (RTA) temperatures. The decrease in the sheet resistance and resistivity…
The effect of annealing and oxygen plasma on the electrical characteristics of gallium oxide films has been investigated. Ga2O3 films with thicknesses of 200–300 nm were formed by the anodic oxidation of n-GaAs wafers with the donor concentration N d = (1–2) × 1016 cm−3. It is shown that, after annealing at 900°C for…
Silver nanoparticles have been extensively used as the anti-microbial agent in medicine. The present study addressed their antifungal potential against phytopathogenic fungi. Ag-SiO2 core–shell nanoparticles (Ag-SiO2 NPs) with an average size of 118.2 ± 4.6 nm were successfully prepared. The released Ag+ slowly throug…
For the past two decades various methods of carbon nanostructures growth have been proposed. Special substrate pretreatment methods are generally used to grow carbon nanowalls on silicon substrates and among them are mechanical and catalytic methods and ion bombardment in an rf discharge with bias. This work describes…
Abstract Summary: Impact poly(propylene) copolymers (IPC) having various ethylene‐propylene rubber (EPR) compositions were prepared using a high activity Ziegler‐Natta catalyst. EPR composition was characterized by temperature rising elution fractionation (TREF) analysis and FT‐IR spectroscopy. Effect of EPR compositi…
Electronic and magnetic properties of zigzag-edged graphene nanoribbons (ZGNR) embedded with titanium (Ti) atoms are studied by means of the first principle calculations. When Ti atoms are positioned near either edge of the ZGNR, the magnetic moment at this edge is rapidly suppressed as the Ti concentration increases,…
A nonlinear inductor physical model based on a simplified Jiles-Atherton theory is presented. The input parameters of this simplified Jiles-Atherton theory can be extracted programmatically, which makes this nonlinear inductor model easy to use in circuit simulations. The corresponding subcircuit has been developed in…
The effect of temperature-time basaltic rock melting regimes on physicochemical properties of the resultant glasses is studied. The high-frequency melting of rocks at elevated temperatures is shown to reduce the glassmaking time, ensure a more complete degassing and homogenization of melts to provide them with a high…
Abstract Potato flour is abundant and less expensive than starch, though its major component is starch. It would therefore seem to be an attractive and viable source of biomass for biodegradable thermoplastic products. This study prepared thermoplastic potato flour (TPF) and thermoplastic potato starch (TPS) films by…
The present study reports the ability of the diatom Planothidium lanceolatum (Brbisson) Lange-Bertalot (P. lanceolatum) to remove hexavalent chromium [Cr(VI)] from aqueous solutions in batch system under varying ranges of pH, contact time and initial ion concentrations by the determination Cr(VI) toxic effects and bio…
The conditions for the formation of a holographic prism of modification II (for which a beam of diffracted rays is induced by a reference laser beam in the plane oriented perpendicularly to the reference beam) are described. A sample of this prism is implemented experimentally, and its response to the signal (referenc…
