Abstract This paper investigates the electromagnetic interference shielding effectiveness (EMI SE) of injection molded ABS disks filled with stainless steel fibers (SSF) and nickel‐coated graphite fibers (NGF). The effects of fiber type, fiber length and weight percentage on SE were studied. Optical microscope (OM) an…
A soft chemistry route is described to obtain glasses in the P 2 O 5 –Na 2 O–ZnO–H 2 O. It is based on the addition of zinc salts to coacervates prepared from sodium polyphosphate. The processing of these coacervates leads to polyphosphate glasses with the same properties as those of glasses prepared in the classical…
The influence of the slenderness (shape effects) of a specimen in compression and of the friction between it and the loading platens on the dissipated energy density and on the compressive strength (strain-softening response) is theoretically and experimentally analysed. The energy dissipated during the process is ass…
Industrially processed duplex stainless steel sheet was investigated after the reheating, the roughing mill and the finishing rolling. Light optical microscopy revealed that the cast structure that existed before rolling was removed and changed into a banded microstructure. During the process, the ferrite-austenite vo…
This paper reports on work that should lead to real-time characterization of nonwovens as they are being produced. Statistical techniques and image processing techniques are employed. The initial results indicate the possibility of better process understanding and control. The goal of this work is to develop affordabl…
Achnanthes longipes Ag. is a marine stalk‐forming diatom that grows in dense biofilms. The effects of cell density, temperature, and light on growth and stalk production were examined in the laboratory to determine how they affected the ability of this diatom to form a biofilm. Stalk production abruptly increased when…
The objectives of this work were to study the microstructural changes and tensile properties that resulted from controlled cooling of a Ti-6Al-4V alloy that had been pancake forged. The alloy was forged at 954°C and specimens cut from the forging were annealed at 975°C for 30 min and cooled down to room temperature at…
The new molybdenum(V) nickel phosphate Na(6)Ni(6)[(Mo(2)O(4))(8)Ni(16)(H(2)PO(4))(4)(HPO(4))(10)(PO(4))(12)(OH)(6)(H(2)O)(8)].66H(2)O (1) was synthesized hydrothermally. The structure (orthorhombic, space group Cccm; a = 23.999(4), b = 36.595(6), c = 20.445(4) A) was solved from single-crystal data. The framework stru…
Abstract The formation of clay minerals was investigated in Spodosols developed in the subalpine belt, with similar exposure, climate and age, but deriving from different parent materials. All the soils were classified as Haplic Podzols and showed the characteristic eluviation and illuviation features of Fe, Al and or…
As2O3, cubic, Fd (3) over barm (No. 227), a = 11.07343(5) Angstrom, V = 1357.8 Angstrom(3), Z = 16, R(P) = 0.056, wR(P) = 0.073, R(I) = 0.068, T = 295 K.
Abstract Using high‐resolution transmission electronic micrograph (HR‐TEM) observation, one can clearly see the pore geometry of the MCM‐41 and SBA‐15 mesoporous silicas to determine that their pore shapes are hexagonal and round, respectively. With the perpendicular orientations of the nanochannels to the electron be…
Tungstate inhibitors are seldom used alone in open recirculating cooling water systems due to their low oxidising ability and high cost. The objective of the present work was to develop efficient synergistic inhibitor combinations comprising sodium silicate and very low concentration of sodium tungstate, keeping in vi…
Solid solubility was examined in Zr‐doped sapphire and Al‐doped yttria‐stabilized zirconia (YSZ) single crystals from 1200° to 1600°C. Specimens were fabricated via ion implantation of single crystals, followed by annealing in air. Secondary ion mass spectroscopy (SIMS) was used to quantify solute redistribution durin…
The XPS spectra of ferrous phosphate were collected with a VSW HA150 using monochromatic Al Kα x-radiation. Monochromatic radiation provides a distinct clarity to the rich peak structure in the valence band of ferrous phosphate due to the absence of interfering x-ray satellites from the intense O 2s region. The valenc…
A new pale blue corrosion product has been found on copper alloy artifacts in the collections of a number of institutions. The corrosion product has been characterized using X-ray powder diffraction, X-ray photoelectron spectroscopy, wavelength X-ray dispersive spectroscopy and Raman microspectroscopy. The corrosion p…
Abstract. Uptake in grass crops of ammonium acetate lactate extractable K (K AL ) and reserve K (interlayer K + structural K) in soil was studied in 16 field experiments at different locations on a range of mineral soil types in Norway. The K uptake from soil, both from K AL and reserve K, was considerable, often even…
For the optimization of electrical insulation design for high temperature superconducting (HTS) cable, evaluation of electrical insulation characteristics especially for butt gap of LN/sub 2/ impregnated cold dielectric (CD) which consists of the wrapped tape insulation impregnated with LN/sub 2/ plays an important ro…
Different enantiomeric isomers, sn-glycerol-1-phosphate and sn-glycerol-3-phosphate, are used as the glycerophosphate backbones of phospholipids in the cellular membranes of Archaea and the remaining two kingdoms, respectively. In Archaea, sn-glycerol-1-phosphate dehydrogenase is involved in the generation of sn-glyce…
Fluorellestadite, Ca 10 (SiO 4 ) 3 (SO 4 ) 3 F 2 , has been synthesized as single phase. This compound crystallizes in the apatite type structure, s.g. P6 3 /m, with parameters a =9.4417(1) Å, c =6.9396(1) Å and V =535.76(1) Å 3 . The refinement of its crystal structure converged to R WP =12.33% and R F =4.58%. The at…
An all-polymer flexible distributed feedback (DFB) laser has been fabricated using a photoinduced surface relief grating (SRG) on an azo-polymer film as a template. The holographically induced SRG on the azo-polymer was transferred onto a flexible film of a UV-curable photopolymer. Optically pumped mirrorless DFB lase…
