A novel polarized light-guide plate (LGP) for the illumination of liquid crystal display is proposed in this paper. For the substrate of the LGP, stress-induced birefringence is introduced to achieve the polarization state conversion. An aluminum sub-wavelength grating (SWG) is designed on the top surface as a polariz…
Abstract We have studied reduced TiO 2 (110) surfaces by combining metastable impact electron spectroscopy (MIES) and UPS(HeI). The reduced Ti species were preparation‐induced: their number density was modified either by adsorption of K atoms or by a combined annealing/oxygen exposure procedure. The emission from the…
The high-temperature oxidation in both air and steam was examined experimentally with pure iron and a Fe-10Cr-0.08C (mass%) ternary ferritic steel. In case of pure iron, the thickness of the oxide scale formed in steam at 923 K for 360 ks was comparable to that of the scale formed in air. On the other hand, in case of…
A numerical model was developed to simulate the competing precipitation of Cu particles on dislocations and in the matrix in Fe-Cu alloys. The nucleation and growth rates and the remaining Cu concentration in the matrix were calculated successively at a large number of fine discrete time steps. In the absence of dislo…
Aqueous solubility is an important parameter for the development of liquid formulations and in the determination of bioavailability of oral dosage forms. Ibuprofen (IB), a nonsteroidal anti-inflammatory drug, is a chiral molecule and is currently used clinically as a racemate (racIB). However, the S form of ibuprofen…
The hydrogen permeation through pure niobium metal was investigated using a gas permeation technique, focusing mainly on the measurements in a highly soluble hydrogen state. The hydrogen diffusion was found to be the rate-determining step for the hydrogen permeation reaction. However, the Sieverts law that the hydroge…
Design of broadband diffractive elements is studied. It is shown that dielectric polarization gratings can be made to perform the same optical function over a broad band of wavelengths. Any design of paraxial-domain diffractive elements can be realized as such broadband elements that may, e.g., give constant diffracti…
In order to develop high hydrogen permeability alloys, structural changes induced by hydrogenation, microstructures and hydrogen permeability Φ were investigated for samples on the straight line connecting the eutectic and the primary phase in the Nb–Ti–Ni phase diagram. Φ was measurable in the alloys containing much…
Abstract In this work, we report the decomposition of gas-phase benzene using plasma-driven catalyst (PDC) system of a single-stage configuration. The decomposition of benzene was affected by the reactor diameter of the surface discharge type PDC reactor. The smaller the reactor diameter, the higher the decomposition…
Alkenyl succinic anhydride (ASA) was added to the agents that would increase the resistance of cellulose fibers to the adsorption of water under neutral/alkaline conditions (at pH's in the range of 7.5-8.5) in the 1960's by 0. Wurzburg and E. Mazzerella of the National Starch and Chemical Company [1]. The sodium salt…
An overview is given of the anomalous behavior of some metals, in particular Fe and Cr, in acidic aqueous solutions during anodic dissolution. The anomaly is recognizable by the fact that during anodic dissolution more material dissolves than would be expected from the Faraday law with the use of the expected valence…
The interactions between luminophore [Ru(bpy)3]2+, and the lacunary Dawson heteropolyanions, [P2W17O61(FeOH2)]7-, [P2W17O61(FeBr)]6- and [P2W17O61]10- were investigated using a combination of photophysics, optical and Raman spectroscopy. Extensive quenching of the excited state of [Ru(bpy)3]2+ was observed in each cas…
Polyacrilonitrile (PAN) nanofibres were prepared by electrospinning of PAN/DMF solution of 15 % wt concentration. Fibre morphology was observed under a scanning electron microscopy. The effects of operating parameters including applied voltage, feeding rate and tip-target distance on the morphology of electrospun PAN…
Tungsten trioxide films on transparent substrates (glass and F : Sn O 2 or indium-tin oxide coated glass) were prepared by various methods like doctor-blading, dip-coating, layer-by-layer painting, and spin-coating. Films of up to 10 × 10 cm were grown and characterized by X-ray diffraction, scanning electron microsco…
A new europium chelate, [4′-(9-anthryl)-2,2′:6′,2′′-terpyridine-6,6′′-diyl]bis(methylenenitrilo) tetrakis(acetate)-Eu3+ (ATTA-Eu3+), has been designed and synthesized as a highly sensitive and selective time-resolved phosphorescence probe for singlet oxygen (1O2). The probe can specifically react with 1O2 to yield its…
The objective of this study was to investigate the effect of alkali treatment on properties of shellac. The native shellac was treated with sodium hydroxide for 15, 30, and 60 min to obtain hydrolyzed shellac. All types of shellac, namely native and hydrolyzed shellac at various times of treatment, were then prepared…
A simple wide-view circular polarizer comprising of a linear polarizer and two biaxial films is proposed. Over the +/-85o viewing cone, the produced polarization is almost circular and the light leakage from the crossed circular polarizers is calculated to be less than 8.23x10(-5), provided that the air-interface surf…
A novel two-dimensional cyanide-bridged polymer [CuII(tren)]{CuI[W(V)(CN)8]} . 1.5H2O (tren = tris(2-aminoethyl)amine) formed via the simultaneous in situ metal-ligand redox reaction of [Cu(tren)(OH2)]2+ and self-assembly with [W(V)(CN)8]3- consists of a {CuI[W(V)(CN)8]} square grid built of CuI centres of tetrahedral…
Driven by shrinking feature sizes, microprocessor “hot-spots” — with their associated high heat flux and sharp temperature gradients — have emerged as the primary “driver” for on-chip thermal management of today’s IC technology. Solid state thermoelectric micro-coolers offer great promise for reducing the severity of…
We have incorporated the photochromic dyes spiropyran and spirooxazine in surfactant templated mesostructured silica particles. Spherical inorganic–organic hybrid pigments with varying dye content were produced by a one-pot synthesis in an aerosol reactor where the internal mesostructure could be controlled. The mesos…
