We report studies of cuprate∕manganate bilayers deposited onto SrTiO3 substrates by laser ablation. A significant difference in the properties of the individual layers is observed depending on the material deposition sequence. The material which is on the bottom of the multilayer shows worse properties, e.g., a critic…

The adsorption of a commercial zein sample on carboxylic (COOH) and alkyl (CH(3)) surfaces was monitored by high time resolution surface plasmon resonance. Zein showed higher affinity and higher mass adsorption on carboxylic than alkyl surfaces. A zein layer specific for each surface was obtained after flushing off lo…

The electronic structure and magnetism in $\mathrm{Na}\mathrm{Ni}{\mathrm{O}}_{2}$ are studied from density-functional calculations and by solving model Hamiltonians, suggested from the density-functional results, to understand the magnetic exchange. The density-functional calculations within the LSDA approximation yi…

Abstract Free‐standing poly(dibenzofuran) (PDBF) films were synthesized electrochemically by direct anodic oxidation of dibenzofuran in mixed electrolytes of boron trifluoride diethyl etherate (BFEE) containing certain amount of trifluoroacetic acid (TFA). The oxidation potential of dibenzofuran in pure BFEE was measu…

Nanoporous silicon films of ultrahigh pore densities and large surface areas have been fabricated by sputtering an Al–Si target and subsequent removal of the deposited film’s Al regions by etching in a sulfuric acid solution. The resulting nanoporous films are mainly composed of amorphous silicon and have cylindrical…

One csp-like gene, called cspA, from the lactic acid bacterium Lactobacillus casei was identified by an inverse polymerase chain reaction approach based on degenerate primers. cspA encodes a protein of 66 amino acid residues, which displays at least 74% identity with Csp proteins of Lactobacillus genera. Northern blot…

Poly(lactic acid) (PLA) was blended with poly(viny1 butyral) (PVB) through solution casting method using chloroform as the common solvent. The films obtained were characterized for miscibility using Differential Scanning Calorimetry (DSC), tensile testing and FTIR spectroscopy. The DSC results showed that the glass-tr…

We study the isotropic $^{13}\mathrm{C}$ Knight shifts of conducting carbon nanotubes from first principles. We find that the values of the shifts provide information about the chirality indices of nanotubes. For carbon nanotubes wider than $0.5\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ the dominating spin-polarization e…

[reaction: see text] A series of 2-amino-2-deoxy-D-[1-13C]aldohexoses and their methyl glycosides was prepared with use of a simplified cyanohydrin reduction route. Four d-aldopentosylamines (arabino, lyxo, ribo, xylo) were prepared from the corresponding D-aldopentoses by reaction with NH3(g) in MeOH solvent, isolate…

This work consists of three parts: the effects of heat treatment (slow cooling and quenching), magnetoannealing, and postannealing of samples with induced anisotropy. It has been found that noncomplete inverse spinel structure was the result after annealing at higher temperature and quenching. Our Mössbauer spectrosco…

The structure factors of colloidal silica dispersions at rather high volume fractions (from 0.055 to 0.22) were measured by small-angle X-ray scattering and fitted with both the equivalent hard-sphere potential model (EHS) and the Hayter-Penfold/Yukawa potential model (HPY). Both of these models described the interact…

A dispersively aligned carbon nanotube array has been achieved between metal electrodes by electric-field assisted manipulation of surface modified single-wall carbon nanotubes (SWCNTs). Surface modification of SWCNTs with octadecylamine (ODA) molecules creates well-dispersed SWCNT solutions and effectively obviates t…
