The effect of water and ozone as the oxidant in the atomic layer deposition (ALD) of aluminum oxide on the ammonium-sulfide-passivated surface is compared using X-ray photoelectron spectroscopy (XPS) after each "half-cycle" of the ALD process. While the first half-cycle of the aluminum precursor tri-methyl aluminum (T…
3D tungsten-oxide-based organic-inorganic microflowers with sizes of 1-5 microm have been prepared by an economical non-aqueous route in a large quantity, and they exhibit visible-light coloration, good reversibility and an enhanced photochromic response.
High-speed atomic force microscopy (HS AFM) in 'contact' mode was used to image at video rate the surfaces of both calcium hydroxyapatite samples, often used as artificial dental enamel in such experiments, and polished actual bovine dental enamel in both neutral and acidic aqueous environments. The image in each fram…
High quality steel production requires extended treatment of the steel in the steel ladle. This has a remarkable impact on the steel ladle refractories, e.g. the need for high performance functional refractories like purging plugs. Operational changes such as increasing tapping temperatures, longer hold times and more…
“Blooming” of tristearin (SSS), a spontaneous formation of flake-like surface structure on a triacylglycerol (TAG), is discussed. It has been well known that blooming of TAGs was closely related to the polymorphism, however, a foundamental question on how the blooming on the micrometre scale was connected with the pol…
Three new closely-related diimine ligands, H(4), H(4) and H(4), were prepared by the condensation of 1,4-diformyl-2,3-dihydroxybenzene () with two equivalents of 2-aminoethanol, 3-aminopropanol or 2-aminophenol, respectively. Three polynuclear complexes, [Ni(II)(7)(H(2))(4)(OAc)(6)(H(2)O)(2)].5H(2)O (.5H(2)O), [Ni(II)…
Abstract—The specific features of TE-wave propagation in a structure fabricated by periodic alternating ferrite and semiconductor layers are investigated. Dispersion characteristics of eigenwaves are calculated. The transmission spectra of an electromagnetic wave oblique incident from the uniform medium onto the multi…
The first Be-based microporous coordination polymer is shown to have a surface area of 3500 m2/g (BET) and a maximum excess H2 uptake of 53 mg/g at 24 bar and 77 K.
Blue-green phosphor, , was prepared by solid-state reaction and optimized by adding as flux. Temperature-dependent luminescence of phosphor was investigated. Furthermore, the luminescence properties of bright blue-green light-emitting diodes (LEDs) fabricated by incorporating this phosphor with an InGaN-based near-UV…
A simple fabrication process of hybrid nanomembranes of epoxy resin and silica is described. Neat poly[(o-creyl glycidyl ether)-co-formaldehyde] (PCGF) and 3-aminopropyl triethoxysilane (APS) were allowed to react at room temperature, diluted with chloroform, and subjected to spin-coating. Upon baking at 120 °C, robus…
The synthesis of ferrocene-based heteroditopic receptors in which the ferrocene moiety is attached to an imidazo[4,5-e]benzothiadiazole or imidazo[4,5-f]quinoxaline is reported. These nitrogen-rich ferrocene derivatives show remarkable ion-sensing properties because of the presence of the redox active ferrocene unit a…
A three-dimensional (3D) method for the estimation of scattering loss due to sidewalls roughness in bent optical waveguides is proposed and validated. The approach, based on Volume Current Method (VCM), has been pointed out to accurately calculate the scattering loss as dependent on curvature radius and wavelength. An…
Titanium dioxide (TiO2) is a promising material for photocatalyst coating. However, it was difficult to fabricate TiO2 coatings which have excellent photocatalytic property by thermal spray processes. Because anatase phase of TiO2 transforms into rutile phase under high temperature i.e. the photocatalytic property of…
Triple helical di-iron complexes, readily prepared through interaction of iron(II) ions with imine-based ligands, are cylinder-shaped tetracations comparable in size and shape to common protein DNA recognition units. They have a strong tendency to coil DNA, and have recently been found to induce formation of three-way…
Further studies on the fresh rhizomes of Polygonatum kingianum led to the isolation of one new spirostanol saponin (25R)-kingianoside G (1), and two pairs mixture of 25R and 25S stereoisomeric spirostanol saponins (25R, S)-pratioside D1 (2a, 2b) and (25R, S)-kingianoside A (3a, 3b), among them 2b and 3b were new spiro…
The steel industry is facing two difficult and urgent tasks to reduce CO2 emissions and to use low-grade iron resources effectively. The utilization of an iron ore–carbon composite is one of the promising methods to solve the former. The latter is concerning to goethite ores such as Australian Marra Mamba and pisolite…
