Novel hydrolysis stable 2-(ω-phosphonooxy-2-oxaalkyl)acrylate monomers 3 with phosphoric acid moieties were synthesized by a three step synthesis via Baylis-Hillman reaction of ethyl acrylate and formaldehyde, and subsequent etherification of the obtained product with diols and phosphorylation using POCl(3). The polym…
Using the projector-augmented plane wave method, we study diffusion and dissociation processes of C(2)H(2) molecules on the ferromagnetic bcc-Fe(110) surface and investigate the formation process of graphene created by C(2)H(2) molecules. The most stable site for C(2)H(2) on the Fe surface is a hollow site and its ads…
Electrophoretic displays (EPDs) have made their way into consumer products. EPDs enable displays that offer the look and form of a printed page, often called “electronic paper”. We will review recent apparatus and method patents for EPD devices and their fabrication. A brief introduction into the basic display operati…
This article describes the morphological and chemical characterization of stimuli-responsive functionalized silicon surfaces provided in parallel by atomic force spectroscopy (AFM) and Fourier transform infrared spectroscopy (FT-IR) enhanced by the single-beam sample reference attenuated total reflection method (SBSR-…
To investigate the noise reduction for an electrical machine, coupled magnetic field and mechanical analyses should be carried out. In this paper, the method of modeling the laminated core using a homogeneous core model with equivalent anisotropic parameters considering the laminated structure in the coupled magnetic…
We report a first-principles description for coherent phonon generation in diamond based on the time-dependent density functional theory. The time-dependent Kohn-Sham equation is solved in real time in order to calculate the electron dynamics in periodic solid exposed to an ultrashort laser pulse. We find that the cal…
The syntheses and characterization of the acentric, B-cation ordered phase Ba 4 CaFe 3 O 9.5 and a topotactically oxidized product Ba 4 CaFe 3 O 10.7 are reported. Utilizing electron diffraction and neutron powder diffraction data, cation ordered structures based on a cubic perovskite lattice were refined for Ba 4 CaF…
Sulfur-doped BaMgAl(10)O(17):Eu(2+) phosphors were synthesized by an environmentally benign synthesis reaction. The photoluminescence spectrum, the energy dispersion spectrum, powder x-ray diffraction, and decay curves were used. The photoluminescence and thermal stability were discussed. It was revealed that sulfur d…
Abstract Polycrystalline La 1− x K x CoO 3 (0 ≤ x ≤ 0.2) rare earth cobaltates have been synthesized by a solution combustion method using glycine as a fuel. The synthesized ceramic materials were characterized by powder X‐ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectrosco…
Abstract Dendritic 2‐ and 4‐arm PMMA‐based star polymers with furan‐protected maleimide at their focal point, (PMMA) 2n ‐MI and (PMMA) 4n ‐MI were efficiently clicked with the peripheral anthracene functionalized multiarm star polymer, (α‐anthryl functionalized‐polystyrene) m ‐poly(divinyl benzene) ((α‐anthryl‐PS) m ‐…
A voltage-pulse method is utilized to investigate the charge-injection-induced time decay of the source-drain current of field-effect transistors with randomly networked single-walled carbon nanotubes (CNTs) as the conduction channel. The relaxation of trapped carriers in the CNT networks can be accounted for by assum…
Buildup factor of gamma and X-ray photons in the energy range of 0.2-2 MeV in water and soft tissue is computed using Monte Carlo code MCNP4C. The results are compared with the buildup factor data of pure water. A new relationship estimating buildup factor as a function of penetration depth, Compton scattering and ene…
Density-functional theory calculations are used to study the adsorption and growth of small Li clusters on MgO(100). The binding of Li is found to be similar to that of Ca in many respects. Monomers bind to oxygen sites on the terrace and diffuse at room temperature to defect sites. A range of defect sites will bind m…
Abstract The effects of three types of additives Y 2 O 3 , La 2 O 3 , and Sm 2 O 3 on the sintering and mechanical behaviors of alumina ceramics were investigated. The bending strengths of alumina ceramics with Sm 2 O 3 and Y 2 O 3 additions were 455 and 439 MPa, respectively, higher than that with La 2 O 3 addition.…
ABSTRACT In the present study, the effects of structure and process parameters on the tactile properties of cotton-knitted fabrics had been investigated. The examined parameters were elastane plating, count of yarns and English gauge of knitting machine. The tactile quality was measured using sensory analysis and inst…
Abstract Current models for magnetoviscosity suggest that replacing the spherical nanoparticles of a conventional ferrofluid with magnetic nanotubes would lead to a stronger field‐induced viscosity enhancement and a much‐improved stability against shear thinning – two important parameters for technological exploitatio…
Computational materials science based on ab initio calculations has become an important partner to experiment. This is demonstrated here for the effect of impurities and alloying elements on the strength of a Zr twist grain boundary, the dissociative adsorption and diffusion of iodine on a zirconium surface, the diffu…
Based on a nanoimprint technique, a new method is proposed for the rapid fabrication of an electrically switchable liquid crystal Fresnel zone lens (SLCFZL). The flow chart of the proposed fabrication method for a SLCFZL is given and a binary SLCFZL is experimentally demonstrated using the proposed method. The diffrac…
Various exotic phenomena have been observed in epitaxially grown films and superlattices of transition-metal oxides. In these systems, not only the interface properties but also the strain-induced modification in the bulk properties play important roles. With the recent experimental activities [Y. Hotta, T. Susaki, an…
During the last 20 years computer simulations based on a quantum-mechanical description of the interactions between electrons and atomic nuclei have developed an increasingly important impact on materials science, not only in promoting a deeper understanding of the fundamental physical phenomena, but also enabling the…
