Although ceramics have been known to mankind literally for millennia, research has never ceased. Apart from the classic uses as a bulk material in pottery, construction, and decoration, the latter half of the twentieth century saw an explosive growth of application fields, such as electrical and thermal insulators, we…

Lindqvist structures: We report the isolation of the all-vanadium(III) analogue (see figure) of the fully reduced (all-vanadium(IV)) hexavanadate structure from formal substitution of the {VIIICl}2+ and {VIVO}2+ fragments. The chemistry can be extended to the analogous CrIII and FeIII cluster anions. Magnetic data for…

Surface-enhanced Raman scattering (SERS) was applied to detecting pentagon-heptagon pairs, the so-called Stone-Wales defect, in single-wall carbon nanotubes (SWCNTs). When a probing laser light was scanned over a SWCNT-dispersed silver surface, two distinct SERS spectra were obtained: (1) temporally stable spectra sim…

The electrodeposition of poly(3,4-ethylenedioxythiophene) (PEDOT) films from aqueous surfactant solution through a two-dimensional poly(styrene) (PS) template onto indium tin oxide (ITO) substrate has been investigated. The polymer grows in the interstitial spaces of the self-assembled PS spheres which were subsequent…

Interfaces between transition metal oxide compounds provide a setting where correlated behavior can emerge. Essential to interface studies are substrates that have a single atomic plane termination. By tuning the vapor pressure of La above the surface of La0.18Sr0.82Al0.59Ta0.41O3 (LSAT) during annealing, single-unit-…

The valence-band structure and the Fermi level (E(F)) position of ferromagnetic-semiconductor GaMnAs are quantitatively investigated by electrically detecting the resonant tunneling levels of a GaMnAs quantum well (QW) in double-barrier heterostructures. The resonant level from the heavy-hole first state is clearly ob…

NEXAFS spectroscopy was used to probe the surface composition and under-water surface reconstruction of thin films of comb-like diblock copolymers with cylindrical and spherical microphases. The polymers consisted of a polystyrene block, and a second block prepared from a styrenic monomer grafted with fluoroalkyl-tagg…

This work reports for the first time the influence of degree of branching (DB) on the thermoresponsive phase transition behaviors of hyperbranched multiarm copolymers. Two series of PEHO-star-PEOs (series A) and PEHO-star-PDMAEMAs (series B) with the hydrophobic DB-variable PEHO core and different kinds of linear arms…

We report a "mild anodization" (MA) process using aluminum oxalate (Alox) as an additive to suppress breakdown of porous anodic alumina (PAA) in the electrolyte of phosphoric acid at high potentials and comparatively high temperatures. It is shown for the first time that continuously tunable pore intervals (D(int)) fr…

Single component and multicomponent nanocrystal (NC) solids represent an exciting new form of condensed matter, as they can potentially capture not only the quantum features of the individual building blocks but also novel collective properties through coupling of NC components. Unlike bulk semiconductors, however, th…

Abstract PP/TiO 2 nanocomposites were prepared from an original method based on the hydrolysis‐condensation (sol–gel method) reactions of titanium alkoxide inorganic precursor premixed with polypropylene (PP) under molten conditions. Nanocomposites with a mean diameter of primary particles lower than 5 nm were then pr…

Coomassie brilliant dyes have high affinity to proteins and high Raman activity, and on the basis of which, we have employed brilliant blue R-250 (BBR) and brilliant blue G-250 (BBG) as surface-enhanced Raman scattering (SERS) labels to probe protein-ligand recognitions. This method differs from previously proposed me…

For many applications, micro- and nanostructured materials show a strong correlation between their geometry and their function. We report here the interfacial precipitation of a copper/alkylamine complex to form Cu(OH)(2) nanofibers in a two-phase system (H(2)O/CH(2)Cl(2)). Their aggregation results in porous microbea…
