Abstract Summary: Phenolic alkylimidazolineamides were prepared and applied as modifiers in order to render layered silicates organophilic and to prepare polymeric nanocomposites. The imidazolineamine, 2‐{2‐[heptadec‐8‐enyl]‐4,5‐dihydro‐1‐imidazol‐1‐yl}‐1‐ethaneamine (IA), was reacted in bulk with one of the two pheno…
Er-doped BaTiO3 samples with nominal compositions BaEr0.08Ti0.92O2.96 and Ba0.96Er0.08Ti0.96O3 have been analyzed with Er–LIII edge XAFS. The first sample shows predominant Er substitution on the Ti site of the perovskite structure, the second one shows almost equal occupancy of Er on Ba and Ti sites, thus assessing t…
Biosynthesis of polyhydroxyalkanoates (PHAs) consisting of 3-hydroxy-alkanoates (3HAs) of 4 to 10 carbon atoms was examined in metabolically engineered Escherichia coli strains. When the fadA and/or fadB mutant E. coli strains harboring the plasmid containing the Pseudomonas sp. 61-3 phaC2 gene and the Ralstonia eutro…
Selective and blanket growth of ruthenium dioxide (RuO2) nanorods have been achieved in chemical vapor deposition (CVD) using bis(ethylcyclopentadienyl)ruthenium. Area-selective growth is demonstrated on a substrate which consists of patterned SiO2 as the non-growth surface and LiNbO3(100) or Zn/Si as the growth surfa…
Coherent Microradiology Directly Observes a Critical Cathode-Anode Distance Effect in Localized Electrochemical Deposition , Seol, S. K., Yi, J. M., Jin, X., Kim, C. C., Je, J. H., Tsai, W. L., Hsu, P. C., Hwu, Y., Chen, C. H., Chang, L. W., Margaritondo, G.
One hydrogen malonato-bridged complex of formula [Cu(Hmal)2] (1) and two polymorphous malonato-bridged complexes of formula [Cu(H2O)(H2mal)(mal)] (2 and 3), in which the three species of the malonate (H2mal, Hmal−, and mal2−) are present, were synthesised and characterized by X-ray diffraction [H2mal = malonic acid].…
Aragonite CaCO3/polymer thin film composites were successfully obtained by using cooperative effects of chitosan, poly(aspartate), and MgCl2. The structures of these composites were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The combination of poly(aspartate) and the magnesium ion…
Mechanically induced free radical (mechanoradical) formation of several substituted celluloses such as carboxylmethyl cellulose, chitin, and chitosan was studied based on electron-spin resonance (ESR) in comparison with those of plasma-induced radicals. Room temperature ESR spectra had multicomponent spectra and were…
A geometric theory is developed for a spherical concave diffraction grating that has variable line spacing and curved grooves and can be produced with existing technology. The aberration coefficients of this grating are determined. A comparison of these coefficients with the corresponding coefficients of holographic g…
Two novel fluorene-trimers were synthesised following a Suzuki-type cross-coupling reaction. Methyl pendant chains in 9-position of the fluorene building blocks ensured a rod-like backbone of a small molecular diameter while the introduction of terminal, flexible n-octyl and n-hexadecyl alkyl chains in the 2- and 7″-p…
The synthesis and characterization is reported of a novel discotic side group polymer based on a predominantly poly(ethylene oxide) backbone to which are attached triphenylene-based mesogenic groups via flexible spacers. The thermal and mechanical behavior of this polymer and its complex with lithium perchlorate are c…
Abstract Schottky contacts were fabricated on composites of high molecular weight polyaniline and pristine multiwalled carbon nanotubes. Physical and electrical characteristics of these organic composite materials were studied by using atomic force microscopy (AFM), scanning electron microscopy (SEM), and electrical m…
A novel methodology for preparation of linear oligopyrroles is presented. Synthetic protocol uses water as a solvent for acid catalysed condensation of an aldehyde or ketone with unsubstituted pyrrole. While the most procedures for the above-mentioned compounds are performed in organic solvents, or large excess of pyr…
A biotinylated Gd-DTPA complex is designed to study the biotin-avidin complexation using the longitudinal relaxivity of this new MRI label, which illustrates the use of MRI contrast agents to probe the formation of supramolecular assemblies in water.
Both intercalated and exfoliated poly(L‐lactide) (PLA) layered aluminosilicate nanocomposites were synthesized and characterized in terms of barrier properties. Intercalated polylactide/montmorillonite nanocomposites were obtained by melt blending PLA and a montmorillonite modified with bis‐(2‐hydroxyethyl)methyl (tal…
Foamed bitumens were obtained by injecting water into hot bitumen using the Foamlab apparatus from SAE (Fayat Group). Three bitumens were studied and the volume of foam obtained under fixed conditions of bitumen temperature and water content, was quantified through the maximum expansion ratio ERm. This parameter reach…
Optimal in vitro conditions are necessary for the development of a strong, well structured, and functional tissue engineered cardiovascular structure eventually designed for implantation. To further optimize in vitro conditions for cell proliferation and extracellular matrix formation in tissue engineering of cardiova…
Grinding a 1 : 1 enantiomeric mixture of chiral transition metal complex crystals and subsequent annealing afforded crystals of a racemic compound by diffusion and rearrangement of component molecules, without melting and without racemization of each enantiomeric species.
We developed novel positive-tone photosensitive polyimide coatings for insulation layers in organic light emitting diode (OLED) displays. We evaluated the features of the novel coatings in comparison to other candidate polymers including novolak resin, acrylic resin, and polybenzoxazole. After curing, the novel coatin…
In the present contribution we report on a novel route to synthesize 2D-polyaniline (2D-PAN) on sulfonated-poly(styrene) (SPS) templates by allowing first monomer assembly followed by chemical oxidation to achieve polymerization. We show that Aplysia neurons grown on 2D-PAN exhibit an unusual growth pattern and adhesi…
