The single-phased K(2)Y(1-x)Eu(x)Zr(PO(4))(3) (x=0~1) phosphors were prepared by solid-state reaction. The greenish-blue Zr(4+)-emission due to the Zr(4+)-O(2-) charge transfer transition is observed in the K(2)YZr(PO(4))(3) (x=0) phosphor under UV excitation. Together with the Zr(4+)-emission, the red emission of Eu(…
The conducting polymer-coated multi-walled carbon nanotubes (MWCNTs) were prepared by template polymerization of aniline and pyrrole on the surface of MWCNTs in order to develop the novel electromagnetic interference (EMI) shielding materials. The conducting polymer phases formed on the surface of MWCNTs were confirme…

This study presents a hepatic tissue engineering application of three-dimensional (3D) porous sponges composed of lactose-silk fibroin (SF) conjugates (Lac-CY-SF) bearing β-galactose residues, hepatocyte-specific ligands. Lac-CY-SF sponges were prepared by freeze-drying, followed by immersion in a series of methanol a…
The molecular weight ( M ) dependence of the center-of-mass surface diffusion coefficient ( D ) is measured for polystyrene adsorbed from chloroform, a good solvent, in the dilute limit of surface coverage. On as-received smooth quartz surfaces, we reproduce D ∼ M −3/2, the same power law observed earlier in aqueous s…
Boron nitride (BN) is a wide bandgap semiconductor with a structure analogous to graphite. Mono- and few-atomic-layer BN sheets have been grown on silicon substrates by microwave plasma chemical vapor deposition from a gas mixture of BF(3)-H(2)-N(2) without using any catalysts. Growth of the BN sheets can be ascribed…
Transparent and conducting SnO 2 thin film has been produced on quartz substrate using rapid thermal oxidation of pure Sn in air at different oxidation temperature and oxidation time. The transmittance T in the visible and NIR was investigated, the allowed direct energy gap was determined to be 3.18 eV at optimum cond…
A series of heterobimetallic complexes, including [M 1 Me(μ-η 5:η 1 -C 5 H 4 PEt 2 ) 2 M 2 Cp*] ( 5a, M 1 = Zr, M 2 = Ru; 5b, M 1 = Hf, M 2 = Ru; 5c, M 1 = Zr, M 2 = Fe) have been prepared and characterized by X-ray analyses. Dehydrogenation of Me 2 NH·BH 3 takes place in the presence of a catalytic amount of these he…
A novel approach to designing nitric oxide (NO) storage and releasing microporous agents based on very stable, zeolite-type silicates possessing framework unsaturated transition-metal centers has been proposed. This idea has been illustrated with ETS-4 [Na(9)Si(12)Ti(5)O(38)(OH)·xH(2)O], a titanosilicate that displays…
The native extracellular matrix (ECM) is composed of a cross-linked porous network of multifibril collagens and glycosaminoglycans. Nanofibrous scaffolds of silk fibroin (SF) and hydroxybutyl chitosan (HBC) blends were fabricated using 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) and trifluoroacetic acid (TFA) as solvents…
The odd couple: The red chromophore of both the rare silicate mineral gillespite (BaFeSi4O10; see picture, left, on sanbornite, BaSi2O5) and the bis(meso-oxolanediolato)ferrate(II) anion in its lithium salt (right) is the square-planar, high-spin-d6 ferrous center. The unusual combination of structure and spin state f…
Functional photoluminescent materials have emerged as a fascinating research subject holding great promise in versatile applications. In this report, photoluminescent lanthanide-organic hybrid nanofibers in hydrogels are fabricated through supramolecular self-assembly, which can serve as functional soft templates to p…
The anisotropic upper critical field, ${H}_{c2}(T)$, curves for ${\mathrm{K}}_{0.8}$Fe${}_{1.76}$Se${}_{2}$ are determined over a wide range of temperatures down to 1.5 K and magnetic fields up to 60 T. Anisotropic initial slopes of ${H}_{c2}$ $~$ $\ensuremath{-}1.4$ T/K and $\ensuremath{-}4.6$ T/K for magnetic field…
Seven polyoxometalate (POM) hybrid materials based on Keggin polyanion building blocks and copper(I)–organic frameworks with pyrazine derivatives, namely, [Cu I 4 (2Et,3Me-Pyr) 5 (SiW 12 O 40 )] ( 1 ), [Cu I 4 (2,6-Pyr) 4 (SiW 12 O 40 )] ( 2 ), [Cu I 4 (2,5-Pyr) 4 (SiW 12 O 40 )(H 2 O) 2 ] ( 3 ), [Cu I 4 (2,3,5,6-Pyr)…
Using a dynamical density functional theory we analyse the density profile of a colloidal liquid near a wall under shear flow. Due to the symmetries of the system considered, the naive application of dynamical density functional theory does not lead to a shear induced modification of the equilibrium density profile, w…
Atomic structures and the defect energetics of three symmetric tilt boundaries of SrTiO${}_{3}$, [$1\overline{1}0$](111)\ensuremath{\Sigma}3, [001](210)\ensuremath{\Sigma}5, and [001](510)\ensuremath{\Sigma}13, were systematically investigated by a first-principles projector augmented wave method and high angular annu…
Ethynylated 2H-cyclohepta[b]furan-2-ones 5-15 have been prepared by Pd-catalyzed alkynylation of 3-iodo-5-isopropyl-2H-cyclohepta[b]furan-2-one (2) with the corresponding ethynylarenes or the reaction of 2-iodothiophene with 3-ethynyl-5-isopropyl-2H-cyclohepta[b]furan-2-one (4) under Sonogashira-Hagihara conditions.

A phalloidin-functionalized hyperbranched conjugated polyelectrolyte (HCPE-phalloidin) is synthesized and used for direct filamentous actin (F-actin) imaging in living Hela cells. Different from commercially available organic dye-phalloidin conjugates, which require sophisticated techniques to be delivered into living…
Abstract Bottle‐brush polymers contain a long flexible macromolecule as a backbone to which flexible side chains are grafted. Through the choice of the grafting density and the length of the side chains the local stiffness of this cylindrical molecular brush can be controlled, but a quantitative understanding of these…
A new solid polymer electrolyte film fabricated by layer-by-layer (LbL) assembly is presented. The electrolyte film consists of four interbonding layers per deposition cycle, which combines electrostatic and hydrogen bonding in the same structure. Linear poly(ethylene imine) (LPEI) and poly(ethylene oxide) (PEO) are u…
