Performing diverse application tests on synthesized metal oxides is critical for identifying suitable application areas based on the material performances. In the present study, Ni-oxide@TiO₂ core-shell materials were synthesized and applied to photocatalytic mixed dye (methyl orange + rhodamine + methylene blue) degr…
A novel poly(urethane-amide) (PUA) was designed using poly(ethylene adipate)tolylene2,4-diisocyanate, piperazine and polyol. Diglycidyl 1,2-cyclohexanedicarboxylate (DGCHD) and 4,4′-ethylenedianiline were used for blend formation. An original approach was adopted for the formation of organic nanoparticle (ONP) using r…
(110) surface for coverages between 0.125 and 1.5 ML are investigated by means of density functional theory calculations. Four different approaches were considered, namely, the PBE exchange-correlation functional and the PBE-D2, vdW-DF and vdW-DF2 methods incorporating van der Waals dispersion interactions of differen…
This paper presents position and vibration control of a flexible robot composed of two rigid and one flexible links. Position is controlled by the current applied to the DC motor armature. To control vibrations of the flexible structure, Shape Memory Alloys (SMA) are used. Due to phase transformations, the SMA can cha…
Abstract Sm(CoFeCuZr) z sintered permanent magnet has been attracting a great deal of attention by virtue of its high‐temperature magnetic properties, low temperature coefficient and good corrosion and oxidation resistance. The microstructures and magnetic properties of Sm(Co bal Fe 0.245 Cu 0.07 Zr 0.02 ) 7.8 sintere…
Polycrystalline and epitaxial zinc nitride (Zn3N2) films were grown by a reactive rf-magnetron sputtering technique. Phase-pure films were grown but XPS results indicated that a small amount of oxygen exists within all Zn3N2–xOx films. We prove experimentally that substitutional O on the N site () can be treated as an…
Techniques to achieve planar anchoring of the director of a lyotropic chromonic liquid crystal (LCLC) have been developed only recently. These techniques range from the very weak anchoring achieved by simply scratching the glass with a very fine abrasive to the very strong anchoring achieved with lithographic techniqu…
New ferrocene based donor–acceptor chromophores depict structure-dependent second-order nonlinear polarizability and charge transport in thin film OFET devices.
Uniformly aligned liquid crystals (LCs) are of crucial importance in a practical application, such as displays, phase modulators and virtual reality devices. Although an alignment layer using polyimide-type polymers can almost perfectly align the LCs, polymer-stabilisation at the surface using pre-mixed monomers has b…
Abstract Studies on Co‐doped Ni–Mn–Ga ferromagnetic shape memory alloys (FSMAs) have been quite active topics in recent years. Unlike previous reports where the amount of Co doping was generally less than 8 at%, in this work Ni 55− x Co x Mn 20 Ga 25 (8.5 ≤ x ≤ 11.0) alloys were studied with high Co doping. Unusual ef…
The transmission properties of armchair- and zigzag-edged graphene nanoribbon junctions between graphene electrodes are examined by means of the standard nonequilibrium Green’s function (NEGF) technique. The quantum transport of electrons is studied through a monolayer graphene strip in the presence of Rashba spin–orb…
Abstract Rice‐like Gd(OH) 3 nanorods were successfully prepared through a facile and rapid microwave‐hydrothermal synthesis method without using any surfactants or templates. X‐ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), t…
This paper describes the effects of both solvent and copolymer block lengths on the stability of electrospun poly(lactic acid)/poly(lactic acid)-b-poly(ethylene glycol) (PLA/PLA-b-PEG) and PLA/PLA-b-PEG-Biotin fibers in water. By tailoring the block length of copolymers PLA-b-PEG, water stability of electrospun fibers…
Upconversion is a unique optical property that is driven by a sequential photon pumping and generation of higher energy photons in a consecutive manner. The efficiency improvement in photovoltaic devices can be achieved when upconverters are integrated since upconverters contribute to the generation of extra photons.…
In this study, we proposed a cost-effective method for preparing graphene nano-flakes (GNFs) derived from carbon nanotubes (CNTs) via three steps (pressing, homogenization and sonication exfoliation processes). Scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), l…
Asymmetric metal‐dielectric nanostructures are demonstrated superior optical properties arising from the combination of strong enhancement of near‐fields and controllable scattering characteristics which originate from plasmonic and high‐index dielectric components. Here, being inspired by the recent advances of the a…
The system based on aluminum phosphinate (OP) and melamine polyphosphate was applied in flame-retardant glass fiber-reinforced polyamide 66. From a qualitative and quantitative point of view, the incorporation of OP played a positive role in obtaining the homodisperse of flame-retardant particles throughout the compos…
Abstract To ameliorate the electrochemical hydrogen storage properties of RE–Mg–Ni–Mn‐based AB 2 ‐type electrode alloys, La element was partially substituted by Ce, and La 1− x Ce x MgNi 3.5 Mn 0.5 ( x = 0, 0.1, 0.2, 0.3, 0.4) alloys were fabricated by casting and melt spinning. The effects of Ce content on structures…
Abstract In present work, the effect of Ge substitution for Mn on crystal structure and martensitic transformation was carefully investigated in magnetic shape memory Ni 50 Mn 36− x Ge x Sn 14 ( x = 0, 1) alloys. From X‐ray diffraction (XRD) patterns, it can be found that each sample possesses cubic austenitic structu…
Shape memory alloy (known dominantly as SMA actuator) which is well known for its actuation, is hereby proposed to be designed exclusively as a sensor. A principle of active force sensing using shape memory effect (SME) of SMA is evolved. SMA wire along with a passive bias (antagonistic) element performs sensing as an…
