Ultrafine Ti powder was prepared by hydrogenation of titanium sponge, mechanical pulverisation, inhibitor coating, vacuum dehydrogenation and inhibitor removal. The effects of technological parameters on Ti powder morphology, particle sizes and oxygen content were investigated. The results showed that after hydrogenat…
This paper presents preliminary research on immobilized Phanerochaete chrysosporium in PVA-alginate-sulfate beads to discolor textile effluents. It is an alternative technique from the current physico-chemicals. The main focus of this study was to determine the colour removal, Chemical oxygen deman (COD) removal and m…
A thin place in a spun yarn with less number of fibers contains more twist and should result in higher cohesion between the fibers. Still a yarn generally fails at thin place. To study the behavior of thin places during tensile testing, ring spun yarn with three different composition and two counts were produced at th…
Preliminary notesThe Preisach hysteresis model is widely used in different engineering disciplines, for example: electrical engineering, mechanical engineering and so on.The Preisach model is a unique tool to describe in a mathematical consistent way the hysteresis phenomenon with non-linearities and memories.The Prei…

Sitka spruce (Picea sitchensis Carr.) specimens, 10 mm along the grain and 20 mm in radial and tangential directions, were exposed to three different RH conditions of 22, 47, and 75% for adsorption and desorption at 30°C controlled by a self-designed temperature conditioning chamber. Specimen weight was measured and t…
The 2013 Special Issue of Australian Journal of Chemistry highlights papers on the current state of research in the field of coordination polymer and indicates briefly where some of the future challenges and opportunities in the field may lie. Coordination polymers, which are also widely known as metalorganic framewor…
Ethanolamine (ETA) is widely used for alkalinization of water in steam cycles of nuclear power plants with pressurized water reactor. When ETA contained wastewater was released, it could increase COD and T-N. The treatment of the COD and T-N from ETA wastewater was investigated using the GAC as particle electrodes in…
Single crystals of the novel copper molybdenum oxides η-CuMoO4 and β-Cu3Mo2O9 are synthesized by a hydrothermal method. Both oxides have triclinic unit cells (space group \(P\bar{1}\)). The lattice constants of η-CuMoO4 are \(a = 6.352\) Å, \(b = 6.986\) Å, \(c = 7.447\) Å, α = 73.53 °, β = 72.98 °, and γ = 84.95 °; t…
Photocatalysts have potential for many applications including environmental remediation and selective catalytic transformations requiring decreased energy consumption. This study presents a systematic approach for the synthesis, characterization, and evaluation of titania-supported silver-based bimetallic nanoparticle…
The pressure-induced organic superconductor β-(BDA-TTP)2FeCl4 [BDA-TTP = 2,5-bis(1,3-dithian-2-ylidene)-1,3,4,6-tetrathiapentalene], which shows a metal–insulator (MI) transition at \(T_{\text{MI}} = 113\) K under ambient pressure, has been found by X-ray study to have a two-fold crystal structure along the \(c\)-axis…
Effects of rf power on the chemical bonding in carbon nitride films deposited using radio-frequency (rf) plasma enhanced chemical vapor deposition in pure methane and nitrogen gas mixtures were investigated. The rf power was varied from 60 to 100 W. The deposition rate of the films increased constantly with increasing…
This letter presents vapor-liquid-solid growth of β-Ga2O3nanowires (NWs) on cost-effective SiO2/Si template and the fabrication of β-Ga2O3NW field emitters. It is found that the β-Ga2O3NWs grown at 950°C are structurally uniform, defect free, and well-oriented with pure monoclinic structure. It is also found that turn…
The molecular geometry optimization, vibrational frequencies and gauge including atomic orbital (GIAO) 1H and 13C chemical shift values of thiazolylazopyrimidine chromophores have been investigated by using density functional theories (DFT/B3LYP, PBE1PBE and BHand-HLYP) and Hartree–Fock (HF) methods with 6–31++G(d,p)…
Radikalisches Dornröschen: Das 5-(2′-Deoxyuridinyl)methyl-Radikal (1) ist ein Schlüsselintermediat in der Thyminoxidation durch reaktive Sauerstoffspezies. Es wird nachgewiesen, dass 1 in Abwesenheit von O2 sowohl Oxidationen als auch Reduktionen eingehen kann. Dies stellt die gängige Lehrmeinung infrage und lässt den…
A kind of three dimensional, sub-diffraction grating with converging-diverging channel working at terahertz regime has been developed on doped silicon wafers by wet etching. By introducing a geometric asymmetry to the vertical direction of the 3D grating, an anti-resonance is observed near the resonant wavelength of t…
Abstract Liposomes have been used widely as carriers for active ingredients in cosmetics because of their ability to encapsulate both hydrophilic and hydrophobic compounds. In this work, fatty acid liposomes were prepared and introduced into olive oil‐in‐water emulsions stabilized by C14–C18 sucrose ester mixtures at…
Amorphous SiO2 nanotubes (NTs) with outer and inner diameters of 35 ± 4 nm and 10 ± 4 nm, respectively, were synthesized through inorganic transcription using organic amphiphilic self-assemblies as templates. By performing three-point bending tests on suspended SiO2 NTs using an atomic force microscope, their elastic…
Abstract Scale deposition is one of the most serious oilfield problems when two incompatible waters interact chemically and precipitate minerals. Typical examples are sea water, with high concentration of sulfate ions and formation waters with high concentrations of calcium, barium, and strontium ions. Mixing of these…
The high-hardness ceramic films, such as TiN, DLC, CrN, etc., are characterized by high hardness and superior tribological performance, which are widely used to improve the wear resistance and service life of components. However, some methods for evaluating the tribological performance of the films have some drawbacks…
