We have performed the first principles calculations on doped δ-Bi 2 O 3 to investigate ionic conductivity. The crystal structure and the ionic conductivity are discussed in total energy and density of states (DOS) from the calculations. The stabilized δ-phase Bi 2 O 3 doped rare-earth metal was explained from DOS data…
In this study, the effects of braid pattern and take-up rate on the mechanical properties of the tubular braided ropes of polypropylene were investigated. Strand fineness of 70 tex and 150 tex, braid pattern of 1/1 and 2/2, and high & low take-up rates were selected For both strand finenesses, the highest values for m…
Preface Co-operative Anistropic Theory of Ferromagnetic Hysteresis Image Reconstruction and Geometrical Analysis of Three-Dimensional Fracture Surfaces in Materials Optical Properties of Pd-free Au-Pt-based High Noble Alloys Gravitational Effects on the Weld Pool shape and Microstructural Evolution of Ni, 304 Stainles…
Hydrogen absorption behavior and hydrogen embrittlement properties of 1000-1800 MPa grade ultra high-strength low alloy TRIP-aided steels with bainitic ferrite matrix were investigated. The TRIP-aided steels absorbed a large amount of hydrogen, compared with the conventional tempered martensitic and bainitic steels. I…
A new concept of maximum power point tracking control method for Thermoelectric Power Generator (TEG) systems has been developed. The virtual load conductance of the load is feedback controlled to maintain the same value of the internal conductance of the thermoelectric (TE) array using DC-DC converter. The prototype…
We present a simple and highly reproductive method for the preparation of thin films consisting of strontium titanate nanoparticles. The films are produced by spin coating of a sol on silicon targets and subsequent annealing under ambient conditions. Analysis by atomic force microscopy shows particles with typical siz…
This paper provides a theoretical context for the types of errors that are likely to occur during the measurement of high frequency cable shield properties. The paper considers a RC dielectric system as it relates to measuring the dielectric properties of cable shield materials.
The effect of training strain, deformation temperature and number of training cycles on the two-way shape memory effect (TWSME) and its stability have been investigated systematically in a Ti46.3Ni44.7Nb9 (at%) wide hysteresis shape memory alloy (SMA). The experimental results indicate that two-way shape memory strain…
The quantitative structure–property relationships (QSPR) have been developed for the stability constants of complexes between 63 different organic ligands and 14 lanthanides. The QSPR models for a series involving a single metal were constructed using only theoretical descriptors for ligands within the CODESSA program…
A process was developed that uses a porous anodic alumina (PAA) mask as a template to electrochemically grow supported metal nanodots and nanowires without the need of aluminum evaporation. A PAA film was fabricated from a high purity Al foil and transferred onto a copper-coated silicon wafer. Nickel was plated with d…
The reaction of [Rh(4)(CO)(9)(mu-CO)(3)] with 3-hexyne to form the butterfly cluster [(mu(4)-eta(2)-3-hexyne)Rh(4)(CO)(8)(mu-CO)(2)] was monitored viain-situ Raman spectroscopy using an NIR laser source, at room temperature and under atmospheric argon using n-hexane as solvent. The collected raw spectra were deconvolu…
Proton-conductive electrolytes of Cs H S O 4 composite were synthesized, and the influence of the matrix on their structure and proton conductivity was investigated at intermediate temperatures. As the supporting matrix, heat-treated Ti O S O 4 hydrate was used. When the matrix heat-treated at 300 ° C was employed, fo…
The surface behaviour of a two-phase polymer mixture depends on the chemical structure of the polymer components, the interaction between the two polymers and the processing conditions. The microscopic morphology and the surface composition need to be known in order to fully utilize the thin film properties. The techn…
The crystal structure of bis(acetylacetonato)lead(II) and the structure of the acetylacetone solvated lead(II) ion in solution have been determined by single-crystal X-ray diffraction and large-angle X-ray scattering (LAXS), respectively. The acetylacetone is deprotonated and acts as a bidentate anionic ligand (acac-)…
We investigate a model of anisotropic diffuse interfaces in ordered FCC crystals introduced recently by Braun et al and Tanoglu et al [3, 18, 19], focusing on parametric conditions which give extreme anisotropy. For a reduced model, we prove existence and stability of plane wave solutions connecting the disordered FCC…
Pulsed laser deposition technique was used for growing thin films of ZnO on Si (100) substrate held at different temperatures (Ts). All the as-deposited films have shown a preferential c-axis orientation associated with varying grain size as a function of Ts ranging from 100to600°C. Current-voltage (I-V) characteristi…
Water films stabilised by hydrophobic particles are found to spread rapidly up the inner walls of a glass vessel containing water and hydrophobic particles when it is shaken; shaking produces unstable particle-stabilised foam bubbles whose coalescence with the air/water interface drives film growth up the inner walls…
Electronic structure of B-doped diamond is studied based on first-principles calculations with supercell models for substitutional and interstitial doping at 1.5–3.1 at.% B concentrations. Substitutional doping induces holes around the valence-band maximum in a rigid-band fashion. The nearest neighbor C site to B show…
Colloidal semiconductor nanocrystals from CdSe show photoluminescence quenching via titration with porphyrin derivatives. This quenching is an indication of the formation of nanoassemblies via surface attachment of pyridyl linker groups. As a consequence of the complex formation, dynamic and/or static interactions bet…
We examined the claw type teeth motor as one application of the soft magnetic composite to a motor core. In order to understand quantitatively the characteristics of the claw type teeth motor, we used the 3-dimensional electromagnetic field analysis to predict its characteristics in advance and manufactured a trial mo…
