The photochemical deposition of a p-type semiconducting copper(I) oxide layer by irradiating visible light in an aqueous solution containing a lactic acid and copper sulfate hydrate is presented. The layer was photochemically stacked on a chemically deposited n-type semiconducting layer/quartz glass substrate, and the…
Pyridoxal 5'-phosphate (PLP)-dependent enzymes represent about 4% of the enzymes classified by the Enzyme Commission. The versatility of PLP in carrying out a large variety of reactions exploiting the electron sink effect of the pyridine ring, the conformational changes accompanying the chemical steps and stabilizing…
The anoxic corrosion of carbon steel liners inside failed copper nuclear waste containers is dependent on the composition of the groundwater to which it is exposed. The influence of carbonate/bicarbonate, sulfate, and chloride in solutions simulating concentrated groundwaters at pH 8.9 on the composition of the corros…
With the introduction of 4,4′-bipyridine N,N′-dioxide (bpdo) ligands, six novel cyano/bpdo mixed-bridged heterometallic 4f–3d compounds {{Ln(III)(bpdo)(H2O)2M(III)(CN)6}·2H2O}n (Ln = Nd(1), Sm(2), Gd(3), Tb(4) with M = Fe; Ln = Nd(5), Sm(6) with M = Co) have been prepared. X-Ray crystallography revealed that they have…
The facile synthesis of the new class of core-extended rylene chromophores, dibenzopentarylenebis(dicarboximide)s, having an intense absorption at 1020-1040 nm, is presented.
The evolution of nickel speciation during the successive preparation steps of Ni-SiO(2) catalysts is studied by UV-Vis-NIR, FT-IR, DTG, TPR and TEM. The study focuses on the effect of the number of chelating ligands in the precursor complexes [Ni(en)(x)(H(2)O)((6-2x))](2+) (en = ethylenediamine, x = 1, 2, 3) on the ad…
We report on the design, fabrication, and characterization of switchable quasi-crystal structures in holographic polymer-dispersed liquid-crystal materials using a multibeam hololithography exposure technique. By interfering multiple coherent laser beams on a liquid crystal-polymer mixture, one can create quasi-crysta…
The data available in the literature on the properties and structure of silicate glasses containing halides are reviewed. The results of measurements of thermal, electrical, and chemical characteristics that illustrate effects associated with the incorporation of halogens (fluorine, chlorine) into the silicate glass m…
Vacuum‐assisted resin transfer molding (VARTM) process was used to fabricate the nanocomposites through integrating carbon nanofiber paper into traditional glass fiber reinforced composites. The carbon nanofiber paper had a porous structure with highly entangled carbon nanofibers and short glass fibers. In this study,…
Major classes of coordination compounds used as electroluminescent materials are surveyed, and their advantages and disadvantages are discussed. The strategy of the directed synthesis of lanthanide(III) complexes promising for use as electroluminescent materials is formulated. The results of studies dealing with the d…
Abstract Purpose – This paper reports on the effects of laundering on physical properties (pilling and edge abrasion) of washed denim fabrics. Design/methodology/approach – Garment washed denim blue jeans were subjected to repeated launderings; the effects of the cycles on pilling and edge abrasion were determined. Da…
We have designed an amphipathic peptide, AM1, that can self-assemble at the air-water interface to form an interfacial ensemble capable of switching between a mechanically strong cohesive film state and a mobile detergent state in response to changes in the solution conditions. The mechanical properties of the AM1 ens…

In this paper a modification of the classical Weibull statistics is developed for nanoscale applications. It is called nanoscale Weibull statistics. A comparison between nanoscale and classical Weibull statistics applied to experimental results on fracture strength of carbon nanotubes clearly shows the effectiveness o…
Synthesis of ordered mesoporous carbons containing Co, Ni, and Fe nanoparticles within the mesostructure was performed through carbonization of poly(furfuryl alcohol) in the presence of metal nitrate inside SBA-15 mesoporous silica templates. The use of the transition metal nitrates, instead of Al catalyst, led also t…
The polymorphism of BaTi1−xFexO3−δ solid solutions: 0 < x < 0.1, prepared by a sol–gel method, has been determined and presented in the form of a temperature–composition phase diagram for T > ∼1000 °C. With increasing x, the high temperature hexagonal polymorph is stabilised to increasingly lower temperatures. The tem…
ZnO film was prepared from 0.1 mol dm − 3 zinc nitrate aqueous solution by the potentiostatic technique using a three-electrode system at 313 – 343 K . The ZnO film was characterized by scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. In addition, measurements of interface pH and…
The synthesis and structural characterization of three new polyoxomolybdenum(V) phosphate frameworks have been achieved by using dimeric {Mo6}2 moieties as inorganic building blocks and protonated organic amines as counter ions. The structure-directing role of the organic cations was investigated and it was shown, tha…
Various CdS nanostructures, including nanoparticle film, bundles of quasi-aligned and well-aligned nanowires, were fabricated with a non-catalytic and template-free MOCVD process. The well-aligned CdS nanowires exhibit unusually high field emission current densities of 225 mA cm(-2) at the applied electric field of 20…
Complexation of linear hexaoxime ligand H6L with Zn2+ and Mn+ (= La3+, Ba2+) afforded a tetranuclear single metallohelicate [LZn3M]n+, whose inversion rate can be modulated by the central metal Mn+.
