Many flooring materials most of them are in natural form are used to manufacture floor tiles for householdflooring purpose. The peoples demand for variety of flooring material Leeds to develop various types ofceramic tiles. In India ceramic industry is fast growing one, more then 400 units of manufacturing ceramictile…
Titanium-boron-nitride (Ti-B-N) films were deposited by reactive magnetron sputtering using a single TiB2 target. The films were deposited under different Ar:N2 ratios. The instrumented indentation technique (nanoindentation), is used to evaluate the mechanical properties of the films. A methodology is presented to ev…
Silicon carbide (SiC) is a promising material for applications in harsh environments. Standard silicon (Si) microelectromechanical systems (MEMS) are limited in operating temperature to temperatures below 130 °C for electronic devices and below 600 °C for mechanical devices. Due to its large bandgap SiC enables MEMS w…
We propose a mechanism to grow a large superlattice of phase domains from a continuum homogenous binary film by sequential activation of self-assembly. Self-assembly was initiated in a small mobile region (where atoms could diffuse) to form a seed pattern, and then the mobile region was shifted gradually. This process…
The solubility of 1,6-naphthalene disulfonic acid disodium in binary sodium chloride + water, sodium sulfate + water, and ethanol + water solvent mixtures was measured in temperature range from (273.15 to 323.15) K by a steady-state method. Results of these measurements were correlated by a modified Apelblat equation.…
The effects of storage temperature and edible coating on the microbiological, physical, and chemical properties and sensory acceptance of fresh-cut organic carrots (Daucus Carota L. cv. Brasília) were investigated. The samples were diced, sanitized in sodium hypochlorite, and the excess water was drained in a centrifu…
Abstract Transformation optics is a methodology that has proven useful in the design of complex media used to alter and control electromagnetic waves in either passive space or regions that contain source distributions. Recently it has been shown that the application of source transformations can reshape field radiati…
In order to promote uniformity between jurisdictions, the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) has developed the National Directory for Radiation Protection, which is a regulatory framework that all Australian governments have agreed to adopt. There is a large and diverse range of indust…
This special issue, “Chiral Optical Materials,” within the inaugural publication of Optical Materials Express, presents research describing recent advances in the field. Research presented focuses on nonlinear optical properties of chiral organic molecules, optical properties of chiral liquid crystals, and chiral nano…
Mesoporous anatase-brookite nanocrystalline titania was synthesized via a novel strategy relying on the combination of soft-templating and solid-liquid method (CSSL), in which the mesostructured titania hybrid was firstly synthesized via cooperative assembly between titanium sulphate and 1-hexadecyl-3-methylimidazoliu…
A silicon cantilever with slender geometry based Micro Electro Mechanical System (MEMS) for nanoparticles mass detection is presented in this work. The cantilever is actuated using a piezoactuator at the bottom end of the cantilever supporting frame. The oscillation of the microcantilever is detected by a self-sensing…
In the title compound, [Cu(C20H17N2O2S)2], the CuII atom is coordinated by the S and O atoms of two 1,1-dibenzyl-3-(furan-2-ylcarbonyl)thioureate ligands in a distorted square-planar geometry. The two O and two S atoms are mutually cis to each other. The Cu—S and Cu—O bond lengths lie within the ranges of those foun…
Based on exact diagonalization and variational cluster approximation calculations we study the relationship between charge transfer models and the corresponding single band Hubbard models. We present an explanation for the waterfall phenomenon observed in angle resolved photoemission spectroscopy on cuprate supercondu…
Escherichia coli DegP protein is a periplasmic protein that functions both as a protease and as a chaperone. In the absence of substrate, DegP oligomerizes as a hexameric cage but in its presence DegP reorganizes into 12 and 24-mer cages with large chambers that house the substrate for degradation or refolding. Here,…
Time-resolved luminescence measurements are performed on high-quality ZnO nanocrystals in a quantum confinement regime prepared by fast cooling and succeeding surface passivation. A very long luminescence lifetime of $~$0.1 $\ensuremath{\mu}$s, which is indicative of the existence of a dark exciton state, is observed.…
The present paper reports the Photoluminescence (PL) of the Sr2CeO4 phosphor, singly doped with Erbium rare-earth ion with different concentrations (0.01, 0.1, 0.2, 0.5 and 1%).The phosphor samples were synthesized using the standard solid state reaction technique. The effect of Er dopant on the structural, morphologi…
Usage of combustion processes for production of target products is less common than the application of catalytic processes. However, there are known examples of production of carbon black, HCl, TiO2 etc. Some research work was done at the Institute of Combustion Problems (Almaty, Kazakhstan) consider the synthesis in…
The work presented here focuses on the investigations of metallo-porphyrins and their gasochromic behavior. Gasochromic materials change their color while they are exposed to a certain gas. So they offer the possibility to develop very selective chemical gas sensors. In the focus of this work is the metallo-porphyrin…
The paper presents a short overview of selected problems related to the numerical analysis of localized deformations. After defining the localization phenomenon and the class of gradient models, two simulation examples are shown. They are applications of the plasticity theory with a Laplacian of the hardening paramete…
Carbon nanotubes (CNTs) have been grown on commercially available silicon carbide (SiC) fabric by the catalytic chemical vapour deposition (CCVD) technique. These CNT coated SiC fabrics were used to develop Silicon Carbide–Carbon Nanotube–Silicon oxy Carbide matrix composites (SiC/CNTs/SiOC) by sol gel technique. Sili…
