In the title compound, [Ag(NH(3))(2)](2)(C(8)H(3)NO(6))·H(2)O, the cations have an almost linear coordination geometry with two ammine ligands and inter-act with the water mol-ecules [Ag⋯O(water) = 2.725 (4) and 2.985 (4) Å]. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds, combined with weak (lone pair)⋯π [O⋯centroid…
This volume of IOP Conference Series: Materials Science and Engineering contains papers from the 11th Workshop of the European Microbeam Analysis Society (EMAS) on Modern Developments and Applications in Microbeam Analysis which took place from 10–14 May 2009 in the Hotel Faltom, Gdynia, Poland. The primary aim of thi…
Ein neues komplexes Silber(II)-Oxid – AgSO4 – wurde durch eine Methathesereaktion von Ag(SbF6)2 und K2SO4 in wasserfreier Flusssäure bei −80 °C oder durch Reaktion von AgF2 mit H2SO4 bei −35 °C erhalten. Die magnetischen Momente der rechteckig-planar koordinierten Ag2+-Ionen in AgSO4 sind über die O-O-Kanten der Sulfa…
We have investigated several classes of strong spin-orbit chalcogenides related to the (Pb,Sn)Te series studied in connection with the Dirac fermion physics in the 1980s. Our first-principle theoretical calculations suggest that ternary chalcogenides TlBiX$_2$ and TlSbX$_2$ (X=Te, Se, S) series harbor small bandgap to…
Recent developments of high strength line pipe steel have seen a decrease in carbon content from 0.25 wt% to less than 0.05 wt% and manganese to less than 1 wt% in an attempt to reduce centreline segregation. The sulphur content should be less than 0.008 wt% as well. However, recent papers argued that low manganese le…
We demonstrate that a SmCo/FeCo based hard/soft nanocomposite material can be fabricated by distributing the soft magnetic α-Fe phase particles homogeneously in a hard magnetic SmCo phase through severe plastic deformation. The soft-phase particle size can be reduced from micrometers to smaller than 15 nm upon deforma…
Abstract When titanium was first introduced commercially in the 1940's, it was considered a wonder metal. In some ways it still is because it offers a superior combination of metallurgical and physical characteristics allowing a wide array of applications to perform to maximum potential. Its greatest use is in aerospa…
Abstract The silver atom has a single s electron hovering over a completed ten‐electron d shell, similar to that of copper and gold. Despite this similarity, there are signal differences in their properties. For silver, its single electron provides the best conductor of electricity, the highest electrical transmittanc…
Abstract Biobased materials refer to products that mainly consist of a substance (or substances) derived from living matter (biomass) and either occur naturally or are synthesized, or it may refer to products made by processes that use biomass. Following a strict definition, many common materials, such as paper, wood,…
Many properties of materials often undergo significant changes in a certain size range. For example, different forms of silicon nanocrystal assemblies have relatively high photoluminescence quantum yield due to morphological and quantum size effects. This chapter describes the main decay channel for photogenerated ele…
Lariat ethers are interesting recognition motifs in supramolecular chemistry. The synthesis of a luminescent lariat aza-crown ether with a carboxyl group appended by azide-alkyne (Huisgen) cycloaddition is presented.
A novel hexameric macrocycle was directly prepared by acid-catalyzed condensation of 2,4-dimethylglycoluril with formaldehyde, as described by V. Sindelar and co-workers in their Communication on page 2378 ff. The macrocycle binds halide anions inside the cavity through twelve C-H ⋅⋅X− hydrogen bonding with high affin…
We investigate correlation functions in a periodic box–ball system. For the two-point functions of short distance, we give explicit formulae obtained by combinatorial methods. We give expressions for general N -point functions in terms of ultradiscrete theta functions.
Cover: The cover illustrates SEM micrographs of LDPE/PET blends and those compatibilized with LDPE-EBAGMA (MB1) and PET-EBAGMA (MB2) masterbatches with the plausible chemical interactions at interface and DSC thermograms of LDPE/PET blends during cooling. LDPE/PET blends exhibit a better morphology with MB1 compared t…
The title compound, 2C(2)H(10)N(2) (2+)·B(14)O(20)(OH)(6) (4-), consists of a centrosymmetric tetra-deca-borate anion and two ethyl-enediammonium cations. The anions are inter-connected through strong O-H⋯O hydrogen bonds into a three-dimensional supra-molecular network with channels along [100], [010], [001] and [111…
THE TITLE COMPOUND [SYSTEMATIC NAME: (8S)-8-methyl-6,9-diaza-spiro-[4.5]decane-7,10-dione], C(9)H(14)N(2)O(2), consists of two connected rings, viz. a piperazine-2,5-dione (DKP) ring and a five-membered ring. The DKP ring adopts a slight boat conformation and the bonded methyl group is in an equatorial position. The f…
Simulations of the polarization switching process near the tip of an edge crack in relaxor ferroelectrics subjected to external electric field have been carried out by employing the time-dependent Ginzburg–Landau theory and the phase-field method. The electric boundary conditions of the crack and the material are assu…
We investigate the electron transport through a mesoscopic ring side-coupled with a quantum dot (QD) in the presence of Rashba spin-orbit (SO) interaction. It is shown that both the Fano resonance and the spin interference effects play important roles in the electron transport properties. As the QD level is around the…
Covalently cross-linked polyvinyl alcohol/epoxy resin membranes were prepared with different ratios of epoxy resin and cross-linking time in polyphosphoric acid (PPA). The structure and the membrane swelling behavior were investigated by small angle X-ray scattering (SAXS). It was found that fewer hydrophilic segments…
Expressions are derived for additional contributions to the linear, quadratic, and cubic electric susceptibilities of molecular crystals that arise when molecules are displaced by the applied electric field. The contributions depend on quantities related to the infrared intensity of lattice vibrations, to the Raman in…
