Ultraviolet photoemission spectroscopic (UPS) and x-ray photoemission spectroscopic (XPS) characterizations of indium tin oxide (ITO) surfaces prepared in ambient environment significantly lower the work function of the ITO surface. This artifact complicates the investigation of ITO surfaces and interfaces using XPS a…
The dielectric properties of high density amorphous ice, which is produced by slow isothermal pressurization $(\ensuremath{\sim}0.1\phantom{\rule{0.3em}{0ex}}\mathrm{GPa}\phantom{\rule{0.3em}{0ex}}{\mathrm{h}}^{\ensuremath{-}1})$ at $130\phantom{\rule{0.3em}{0ex}}\mathrm{K}$, have been studied by dielectric spectrosco…
The crystal structure of [Fe(bt)2(NCS)2] (A) was determined by X-ray diffraction at 293 and at 150 K in order to analyze the structural changes associated with the spin transition. The space group is P1 with Z = 2 at both temperatures. Lattice constants are as follows: a = 8.5240(4), b = 11.0730(6), c = 12.5300(8) at…
Abstract The gelatinous layer (G-layer) formed on the lumen wall in early- and latewood fibres of poplar and birch tension wood was characterised using a novel molecular marker specific for crystalline cellulose in conjunction with fluorescence and FE-SEM microscopy. Crystalline cellulose was localised using a cloned…
To evaluate the appropriate time frame for applying mechanical stimuli to induce mesenchymal stromal cell (MSC) differentiation for ligament tissue engineering, developmental cell phenotypes were monitored during a period of in vitro culture. MSCs were seeded onto surface-modified silk fibroin fiber matrices and cultu…
We have applied one-dimensional (1D) 1 H MAS NMR, 27 Al → 1 H CP MAS NMR, as well as 2D 27 Al triple-quantum (3Q) MAS NMR, 27 Al → 1 H heteronuclear correlation (HETCOR) and high-resolution 3QMAS/HETCOR NMR techniques to KAlSi 3 O 8 (Or), NaAlSi 3 O 8 (Ab) and NaAlSiO 4 (Ne) glasses containing 0~2 wt% H 2 O to shed li…
It has been shown that a metal film with a one-dimensional array of subwavelength cut-through slits can be accurately modeled as an anisotropic and uniform metamaterial film with nondispersive electric permittivity [epsimacr] and magnetic permeability [mumacr] tensors. This model has an interesting scaling property: T…
A layer-by-layer assembly composed of avidin and 2-iminobiotin-labeled poly(ethyleneimine) (ib-PEI) was prepared on the surface of a platinum (Pt) film-coated quartz resonator, and an electrochemically induced disintegration of the avidin-ib-PEI assembly was studied using a quartz crystal microbalance. The resonance f…
Photoinduced electron transfer (ET) and excitation energy transfer (ENT) reactions in monomer and slipped-cofacial dimer systems of a directly linked Zn porphyrin (Por)-Zn phthalocyanine (Pc) heterodyad, ZnPc-ZnPor, were investigated by means of the picosecond and femtosecond transient absorption spectroscopies. In th…
Removal of organic compounds and inorganic nutrients from aquaculture wastewaters prior to discharge can not only minimize deterioration of receiving water quality, but it could also be further reused to culture prawn, fish and shellfish. Chitosan can be used as a coagulant, adsorbent, or bactericide; therefore it has…

This study evaluated the endothelial function and mechanical properties of tissue-engineered vascular autografts (TEVAs) constructed with autologous mononuclear bone marrow cells (MN-BMCs) and a biodegradable scaffold using a canine inferior vena cava (IVC) model. MN-BMCs were obtained from a dog and seeded onto a bio…
A dinuclear Ni(II) complex involving tetrathiafulvalene (TTF) radicals as ligands has been prepared and characterized, [Ni2(mu-Cl)2(L*+)2(I3)4(I2)3.(H2O)2.(C4H8O)3 (1), L = 4,5-bis(2-pyridylmethylsulfanyl)-4',5'-ethylenedithiotetrathiafulvalene. There are two types of intramolecular magnetic exchange interactions, nam…

Ag-Pd and Au-Pd (alloyed or core-shell) catalysts were synthesised by radiolytic reduction (gamma rays or electron beam). Selective hydrogenation of buta-1,3-diene was performed with these different nanoparticles deposited on alumina in order to investigate composition and structure effects on catalytic performances.…
By using the study of the lattice energy and the structural parameters of binary inorganic crystals, a new parameter reflecting the thermal expansion property has been found, the relation between the linear expansion coefficient and new parameter has been established. A semiempirical method for evaluation of linear ex…
Zeolite-intercalated semiconductor quantum dots (QDs) have long been proposed to give very high third-order nonlinear optical (3NLO) responses. However, measurements of their 3NLO responses have not been possible due to the lack of methods to prepare optically transparent QD-incorporating zeolite films supported on op…
The immunoglobulin G (IgG) binding ZZ domain of protein A from Staphylococcus aureus was fused to the N terminus of the polyhydroxyalkanoate (PHA) synthase from Cupriavidus necator. The fusion protein was confirmed by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry and mediated formation o…
We studied the effect of particle size on the structure and magnetic properties of La0.6Pb0.4MnO3 compounds with particle diameters varying from 5to100nm. With decreasing particle size, the increase of the rhombohedral distortion narrows the bandwidth WO2p and hence results in the decrease of ferromagnetic transition…
