A continuous series of Bi2W1 − x Mo x O6 solid solutions between the n = 1 Aurivillius phases Bi2WO6 and Bi2MoO6 with a polar orthorhombic structure (γ-phase) have been prepared by solid-state reactions at 850 (0 < x ≤ 0.3) and 530–640°C (0.3 ≤ x < 1), and their thermal and electrical properties have been studied thro…
Review on COL1A1 (collagen, type I, alpha 1), with data on DNA, on the protein encoded, and where the gene is implicated.
Fluorescent nanoparticles were prepared via adsorption of the conjugated polyelectrolyte poly[5-methoxy-2-(3-sulfopropoxy)-1,4-phenylenevinylene] (MPS-PPV) onto 50 and 100 nm aminosilane functionalized silica beads. The particles were investigated via ensemble and single-molecule or -particle spectroscopy techniques t…
The results of studying aluminum-matrix composite materials (CMs) reinforced ex situ by disperse nanosize powders obtained by plasma-chemical synthesis, as well as by intermetallic phases formed by in situ reactions, are presented. The structure and tribological properties of aluminum-matrix CMs have been examined. Th…
This report describes photoluminescence studies of copper-containing [2]pseudorotaxanes that mimic elements of functioning molecular machines. Excitation with visible light induces a formal oxidation of the metal center and simulates an actuation process. In all four [2]pseudorotaxanes studied, the ring ligand is the…
The cadmium(II) complex with the condensation product of salicylaldehyde and 3-(pyridine-2-yl)-5-(2-aminophenyl)-1H-1,2,4-triazole (H 2 L), Cd 2 (H 2 L) 2 (OAc) 4 · 3EtOH, is synthesized. Its crystal structure is studied by X-ray diffraction analysis. In the centrosymmetric binuclear complex (Cd…Cd 3.938(1)Å), the Cd…
Liuchiu Island is an uplifted coral-reef island located off southwestern Taiwan. A total of four soil pedons, labeled as LC-1 and LC-2 from the Holocene terraces and LC-3 and LC-4 from the Pleistocene terraces, were sampled on the island for this work. These soils were siliceous, and were characterized by enrichment o…
It is known that ionizing radiation (x ray, gamma rays, and electrons) can induce numerous changes in the physical properties of glasses. The most obvious effect is visible coloration, which is caused by the accumulation of color centers (defects) in the irradiated volume. The application of such induced color centers…
Daviel, E., Sanborn, P., Tarnocai, C. and Smith, C. A. S. 2011. Clay mineralogy and chemical properties of argillic horizons in central Yukon paleosols. Can. J. Soil Sci. 91: 83–93. Wounded Moose paleosols occur on Middle Pleistocene and older glacial deposits in central Yukon, and exhibit thick sola with distinctive…
In order to reproduce the V‐shape structure characteristics of the close dart leader/return stroke field change, we employ two existing models, one for the “source charge” leader model and the other for MTLL return stroke model, both based on the assumption of uniform leader charge distribution along the channel and t…
The diphenylalanine (FF) motif has been widely used in the design of peptides that are capable of forming various ordered structures, such as nanotubes, nanospheres and hydrogels. In these assemblies, FF based peptides adopt an antiparallel structure and are stabilized by π — π stacking among the phenyl groups. Here w…
Molecular-dynamics simulations are used to study the phase behavior of a single linear multiblock copolymer with blocks of A- and B-type monomers under poor solvent conditions, varying the block length N, number of blocks n, and the solvent quality (by variation of the temperature T). The fraction f of A-type monomers…
Single crystals of Cs2(UO2)(NO3)Cl3 were prepared by a hydrothermal method at 205 °C. The crystal structure has been solved by Direct Methods: monoclinic, P21/n, a = 10.3748(13), b = 9.4683(13), c = 12.5535(16) Å, β = 110.280(2)◦, V = 1156.7(3) Å3, R1 = 0.029. In the structure, strongly bonded linear uranyl cations UO…
0C with differences times of reaction. The thin films were characterized by X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM), optical absorption spectroscopy and Atomic Force Microscopy (AFM). The XRD measurements showed that the films have hexagonal polycrystalline structure and the crystallites are orient…
Using cohydrolysis of aluminum alkyls with tetraethyl orthosilicate, we have synthesized aluminosiloxane oligomers, which have been pyrolyzed to give homogeneous high-purity aluminosilicates with a controlled Al: Si molar ratio.
Abstract Although in recent years, the ash residues produced from municipal solid waste incinerators (MSWI) in Taiwan have been decreased gradually due to the public awareness of waste classification, it is still necessary to find a suitable landfill site to dispose these wastes safely and economically. For this reaso…
Amorphous zirconium tungstate, an inorganic ion-exchanger, was synthesized under optimum conditions and used as a cation-exchange material for the removal of caesium ions from radioactive waste solutions under simulated conditions using batch techniques. The physical and chemical properties of the synthesized ion-exch…
High-accuracy X-ray diffraction measurements of protein crystals are an important process to determine three-dimensional structures. Investigators must manipulate crystals in X-ray diffraction measurement. Protein crystals are exposed to evaporation during manipulation, and their exposure to evaporation for a long tim…
The aim of this study was to investigate the homogeneity of the bulk nanocrystalline titanium rods obtained by Hydrostatic Extrusion (HE). The investigated material was commercially pure titanium grade 2. The final products of extrusion were nanocrystalline rods with diameters of 7 and 10 mm and lengths of about 250 m…
The magnetic phase diagram of terbium manganite in a magnetic field Hz directed along the polarization is described phenomenologically. This description is in good agreement with experiment for certain relationships among the system parameters. It is shown that terbium ion spins contribute to the observed linear depen…
