The quinter-nary thio-phosphate Cs(0.5)Ag(0.5)Nb(2)PS(10).

ABSTRACT: The quinter-nary thio-phosphate Cs(0.5)Ag(0.5)Nb(2)PS(10), cesium silver tris-(disulfido)[tetra-thio-phosphato(V)]diniobate(IV), has been prepared from the elements using a CsCl flux. The crystal structure is made up of (?) (1)[Nb(2)PS(10)] chains expanding along [010]. These chains are built up from bicapped trigonal-prismatic [Nb(2)S(12)] units and tetra-hedral [PS(4)] groups and are linked through a linear S-Ag-S bridge, forming a two-dimensional layer. These layers then stack on top of each other, completing the three-dimensional structure with an undulating van der Waals gap. The disordered Cs(+) ions reside on sites with half-occupation in the voids of this arrangement. Short [2.8843?(5)?Å] and long [3.7316?(4)?Å] Nb-Nb distances alternate along the chains, and anionic S(2) (2-) and S(2-) species are observed. The charge balance of the com-pound can be represented by the formula [Cs(+)](0.5)[Ag(+)](0.5)[Nb(4+)](2)[PS(4) (3-)][S(2) (2-)](3).

KNb(1.75)V(0.25)PS(10).

Project description:The title compound, potassium diniobium vanadium phospho-rus deca-sulfide, KNb(1.75)V(0.25)PS(10), was obtained by reaction of the elements with a eutectic mixture of KCl/LiCl. It is isostructural with the quaternary KNb(2)PS(10), but the Nb sites are occupied by statistically disordered Nb (87.5%) and V (12.5%) atoms. The structure is composed of anionic (∞) (1)[M(2)PS(10)](-) chains (M = Nb/V) separated from each other by K(+) ions. The chain is composed of [MS(8)] distorted bicapped trigonal prisms and [PS(4)] tetra-hedra. There are no inter-chain bonding inter-actions. The crystal used for the X-ray analysis was a racemic twin.

Cs(10)Ta(29.27)o(78).

Project description:Single crystals of caesium tantalate(V), Cs(10)Ta(29.27)O(78), were obtained as a serendipitous product in a welded tantalum ampoule by a blank reaction of CsBr and bis-muth subnitrate [Bi(5)O(OH)(9)(NO(3))(4)] with the container material. The crystal structure of the title compound is made up of a three-dimensional framework constituted by two types of layers, viz. (Ta(6)O(15))(n) and (Ta(3)O(9))(n), parallel to (001), which are linked together by TaO(6) octa-hedra (3m. symmetry) along [001]. This framework has cavities where three independent Cs(+) ions (3m. and m2 symmetry, respectively) are located. The compound reveals a Ta deficiency at one trigonal prismatic coordinated site (m2 symmetry). The composition of the title compound was verified by energy-dispersive X-ray analysis of single crystals.

Full spectrum fluorescence lifetime imaging with 0.5 nm spectral and 50 ps temporal resolution.

Project description:The use of optical techniques to interrogate wide ranging samples from semiconductors to biological tissue for rapid analysis and diagnostics has gained wide adoption over the past decades. The desire to collect ever more spatially, spectrally and temporally detailed optical signatures for sample characterization has specifically driven a sharp rise in new optical microscopy technologies. Here we present a high-speed optical scanning microscope capable of capturing time resolved images across 512 spectral and 32 time channels in a single acquisition with the potential for ~0.2 frames per second (256 × 256 image pixels). Each pixel in the resulting images contains a detailed data cube for the study of diverse time resolved light driven phenomena. This is enabled by integration of system control electronics and on-chip processing which overcomes the challenges presented by high data volume and low imaging speed, often bottlenecks in previous systems.

K(0.8)Ag(0.2)Nb(4)O(9)AsO(4).

Project description:The title compound, potassium silver tetra-niobium nona-oxide arsenate, K(0.8)Ag(0.2)Nb(4)O(9)AsO(4), was prepared by a solid-state reaction at 1183 K. The structure consists of infinite (Nb(2)AsO(14))(n) chains parallel to the b axis and cross-linked by corner sharing via pairs of edge-sharing octa-hedra. Each pair links together four infinite chains to form a three-dimensional framework. The K(+) and Ag(+) ions partially occupy several independent close positions in the inter-connected cavities delimited by the framework. K(0.8)Ag(0.2)Nb(4)O(9)AsO(4) is likely to exhibit fast alkali-ion mobility and ion-exchange properties. The Wyckoff symbols of special positions are as follows: one Nb 8e, one Nb 8g, As 4c, two K 8f, one Ag 8f, one Ag 4c, one O 8g, one O 4c.

Vibrational spectroscopy of metal methanesulfonates: M?=?Na, Cs, Cu, Ag, Cd.

Project description:In this work, we have used a combination of vibrational spectroscopy (infrared, Raman and inelastic neutron scattering) and periodic density functional theory to investigate six metal methanesulfonate compounds that exhibit four different modes of complexation of the methanesulfonate ion: ionic, monodentate, bidentate and pentadentate. We found that the transition energies of the modes associated with the methyl group (C-H stretches and deformations, methyl rock and torsion) are essentially independent of the mode of coordination. The SO3 modes in the Raman spectra also show little variation. In the infrared spectra, there is a clear distinction between ionic (i.e. not coordinated) and coordinated forms of the methanesulfonate ion. This is manifested as a splitting of the asymmetric S-O stretch modes of the SO3 moiety. Unfortunately, no further differentiation between the various modes of coordination: unidentate, bidentate etc?…?is possible with the compounds examined. While it is likely that such a distinction could be made, this will require a much larger dataset of compounds for which both structural and spectroscopic data are available than that available here.

K(0.12)Na(0.54)Ag(0.34)Nb(4)O(9)AsO(4).

Project description:Potassium sodium silver tetra-niobium nona-oxide arsenate, K(0.12)Na(0.54)Ag(0.34)Nb(4)AsO(13), synthesized by solid-state reaction at 1123 K, adopts a three-dimensional framework delimiting tunnels running along [001] in which occupationally disordered sodium, silver, and potassium ions are located. Of the 11 atoms in the asymmetric unit (two Nb, one As, one Ag, one K, one Na and fiveO), nine are located on special positions: one Nb and the K, Ag, Na and two O atoms are situated on mirror planes, the other Nb is on a twofold rotation axis, and the As atom and one O atom are on sites of m2m symmetry.

Redetermination of AgNb(2)PS(10) revealing a silver deficiency.

Project description:In comparison with a previous crystallographic study [Goh et al. (2002 ?). J. Solid State Chem.168, 119-125] of the title compound, silver diniobium tris-(disulfide) tetra-thio-phosphate(V), that reports a full occupation of the silver position and isotropic displacement parameters for the atoms, the current redetermination reveals a silver deficiency with a site-occupation factor of 0.88?(1) and reports all atoms with anisotropic displacement parameters. The structure of Ag(0.88)Nb(2)PS(10) is composed of (?) (1)[Nb(2)PS(10)] chains, which are built up from pairs of distorted bicapped trigonal-prismatic [NbS(8)] polyhedra forming [Nb(2)S(12)] dimers and of tetra-hedral [PS(4)] groups. These chains are connected via the statistically disordered Ag(+) ions, forming double layers. Adjacent layers are stacked solely through van der Waals forces into a three-dimensional structure. Short and long Nb-Nb distances [2.880?(1) and 3.770?(2)?Å, respectively] alternate along the chain and S(2) (2-) and S(2-) anionic species are observed.

Facile Synthesis of Mono-Dispersed Polystyrene (PS)/Ag Composite Microspheres via Modified Chemical Reduction.

Project description:A modified method based on in situ chemical reduction was developed to prepare mono-dispersed polystyrene/silver (PS/Ag) composite microspheres. In this approach; mono-dispersed PS microspheres were synthesized through dispersion polymerization using poly-vinylpyrrolidone (PVP) as a dispersant at first. Then, poly-dopamine (PDA) was fabricated to functionally modify the surfaces of PS microspheres. With the addition of [Ag(NH₃)₂]⁺ to the PS dispersion, [Ag(NH₃)₂]⁺ complex ions were absorbed and reduced to silver nanoparticles on the surfaces of PS-PDA microspheres to form PS/Ag composite microspheres. PVP acted both as a solvent of the metallic precursor and as a reducing agent. PDA also acted both as a chemical protocol to immobilize the silver nanoparticles at the PS surface and as a reducing agent. Therefore, no additional reducing agents were needed. The resulting composite microspheres were characterized by TEM, field emission scanning electron microscopy (FESEM), energy-dispersive X-ray spectroscopy (EDS), XRD, UV-Vis and surface-enhanced Raman spectroscopy (SERS). The results showed that Ag nanoparticles (NPs) were homogeneously immobilized onto the PS microspheres' surface in the presence of PDA and PVP. PS/Ag composite microspheres were well formed with a uniform and compact shell layer and were adjustable in terms of their optical property.
