Through systematic density functional calculations using the full potential linearized augmented plane-wave (FLAPW) method, the rhombohedral magnetostriction (\ensuremath{\lambda}${}_{111}$) of Fe${}_{100\ensuremath{-}x}$Al${}_{x}$ and Fe${}_{100\ensuremath{-}x}$Ga${}_{x}$ alloys are studied for $x$ up to 25. Theoreti…
Copolymers featuring pentafuorophenyl ester and o-nitrobenzyl (ONB) protected amine moieties have been prepared. Upon UV irradiation, the ONB protected amine group was released, which subsequently induced a crosslinking by a spontaneous reaction with pentafluorophenyl esters, resulting in stable, reactive patterned th…
A novel adhering polyurethane (PU), based on hydrolysable tannins that contain a number of active sites, was successfully synthesized and characterized. The active sites were catechol groups in the hydrolysable tannins, which were used as a substitute for dopamine. This efficient, universal, and low cost coating based…
On May 16, 1902, a baby was born in Sendai, Japan, and named Tetsuo by his parents Juichi and Toyo† Nozoe (Figure 1). The name Tetsuo Nozoe would one day become well known in the chemical world. His father, Juichi, was a lawyer and a politician, who at one time served as a member of the National Diet. As is common in…
The local dielectric environment dependent local field enhancement properties in double concentric silver nanotubes have been obtained by using the plasmon hybridization method and quasi-static calculation. Because of the inserted silver nanotube, the geometrical parameter controlled intertube coupling greatly improve…
Polyethylene glycol (PEG) is used to induce the self-assembly of phenol/formaldehyde (PF) resol and triblock copolymer Pluronic P123 by improving the interaction between the PF resol and P123, leading to the formation of a two-dimensional (2D) hexagonal ordered mesostructure. Ordered mesoporous polymers (OMPs) prepare…
The crystal structure, phase stability, and oxide-ion diffusion of nanocrystalline ceria–zirconia materials are unresolved important issues, in particular at high temperatures, where the ceria–zirconia catalysts work efficiently. Here, we report a high-temperature neutron diffraction study of nanocrystalline [10.1(7)…
The photoelectrochemical behavior of n-type ZnO nanowire arrays was compared to the behavior of single crystalline n-ZnO photoelectrodes in contact with either 0.50 M K 2 SO 4 (aq) at pH 6.0 or Fe(CN) 4 3–/4– (aq). The use of a thin film of ZnO as a seed layer produced dense nanowire arrays in which the ZnO nanowires…
Broadband near-infrared luminescence covering 900 to 1600 nm has been observed in Bi-doped oxyfluoride silicate glasses. The partial substitution of fluoride for oxide in Bi-doped silicate glasses leads to an increase of the intensity and lifetime of the near-infrared luminescence and blue-shift of the near-infrared e…
Controlled-rheological polypropylene random copolymer (CRPPR) and β-nucleated CRPPR were prepared through peroxide-initiated reactive extrusion and their crystallization behaviors were comparatively investigated. Rheological experiments indicated that all degraded samples acquired better flow properties than undegrade…
Chalcogenide nanocrystals or quantum dots (QDs) such as CdSe and PbSe have great potential as absorbers for QD-sensitized solar cells, but their practical utility is limited by fast degradation when exposed to ambient environments. Here we present results showing that small organic molecules acting as hole-accepting l…
We have developed a novel approach for the fabrication of self-assembled porous materials with uniaxial tubular pores. The approach is based on the use of microtubes formed by stimuli-induced rolling of polymer bilayers consisting of hydrophobic and stimuli-responsive hydrophilic polymers. Different objects, for examp…
We report a combined experimental and theoretical study investigating small zinc oxide clusters. A laser vaporization source and a time-of-flight (TOF) mass spectrometer are employed to produce and identify anionic clusters in the Zn(n)O(m) (n = 1-6, m = 1-7) size regime. The adiabatic detachment energy (ADE) and vert…
Networks of pristine high quality single walled carbon nanotubes (SWNTs), the SWNTs after Ar-plasma treatment (from 2 to 12 min) and carbon nanobuds (CNBs) have been tested for ethanol vapor sensing. It was found that the pristine high quality SWNTs do not exhibit any ethanol sensitivity, while the introduction of def…
The palladium oxide cluster Pd(6)O(4)(+) is formed as the sole product upon reaction of a bare palladium cluster Pd(6)(+) with molecular oxygen in an octopole ion trap under multicollision conditions. This oxide cluster is found to be resistant to further oxidation over a large temperature range, and further O(2) mole…
Sodium borohydride (NaBH4) determination, both qualitative and quantitative, is of great significance in a plethora of areas. These include NaBH4 for energy systems such as direct borohydride fuel cells and in hydrogen production and storage, as well as use as a reducing agent in organic and inorganic synthesis reacti…
The effects of high pressure (up to 30 GPa) on the structural properties of lithium and calcium carbide, Li(2)C(2) and CaC(2), were studied at room temperature by Raman spectroscopy in a diamond anvil cell. Both carbides consist of C(2) dumbbells which are coordinated by metal atoms. At standard pressure and temperatu…
Escherichia coli can rapidly switch to the metabolism of l-arabinose and d-xylose in the absence of its preferred carbon source, glucose, in a process called carbon catabolite repression. Transcription of the genes required for l-arabinose and d-xylose consumption is regulated by the sugar-responsive transcription fac…
Electrode materials with a three-dimensional (3D) network structure and high-conductivity structural scaffolds are indispensable requirements for the development of in-plane supercapacitors with a superior performance. Herein, the highly tunable thin films with oriented interpenetrating network structures are prepared…
A new strategy was developed and applied in monitoring pH response and enzyme activity based on fluorescence emission red shift (FERS) of the conjugated polymer PPP-OR10 induced by the inner filter effect (IFE) of nitrobenzene derivatives. Neutral poly(p-phenylenes) functionalized with oligo(oxyethylene) side chains (…
