Lithium ion conductivity of molecularly compatibilized chitosan–poly (aminopropyltriethoxysilane)–poly(ethylene oxide) nanocomposites
(Elsevier , Science Ltd., 2007-05-31)
Films of composites of chitosan/poly(aminopropyltriethoxysilane)/poly(ethylene oxide) (CHI/pAPS/PEO) containing a fixed amount of lithium
salt are studied. The ternary composition diagram of the composites, reporting ...
Structure and optical characterization of photochemically prepared ZrO2 thin films doped with erbium and europium
(ELSEVIER, 2008-09-01)
Zirconium oxide thin films loaded with 10, 30 and 50 mol% lanthanide ions (Er or Eu) have been successfully prepared by direct UV (254 nm) irradiation of amorphous films of beta-diketonate complexes on Si(100) substrates, ...
A coumarinylaldoxime as a specific sensor for Cu2+ and its biological application
(Elsevier, 2014)
In this Letter we present a new probe, (E)-7-(diethylamino)-2-oxo-2H-chromene-3-carbaldehyde oxime
(JB), which can detect Cu2+ ions in HEPES buffer under physiological conditions. Benesi–Hildebrand and
Job plots demonstrate ...
Two malic enzymes in Pseudomonas aeruginosa
(American Society of Microbiology, 1973)
Cell-free extract supernatant fluids of Pseudomonas aeruginosa were shown to lack malic dehydrogenase but possess a nicotinamide adenine dinucleotide (NAD) - or NAD phosphate (NADP)-dependent enzymatic activity, with ...
Inorganic Fullerenes: From Lamellar Precursors to Functionalized Nanotubes
(Trans Tech Publications Ltd., 2007)
The intercalation of long-chain primary amines into the laminar matrices of MoS2 or
V2O5-gel leads to well ordered, lamellar organic-inorganic nanocomposites. Powder X-ray
diffraction analysis, stoichiometry determined ...
Lanthanides-clay nanocomposites: Synthesis, characterization and optical properties
(2009)
Complexes of Europium(III) and Terbium(III) with 2,2-bipyridine and 1,10-phenanthroline were inserted into Na-bentonite by ion exchange reactions at room temperature. The products display interlaminar distances and ...
ESR, electrochemical and reactivity studies of antitrypanosomal palladium thiosemicarbazone complexes
(Elsevier B.V., 2008-08)
Cyclic voltammetry (CV) and electron spin resonance (ESR) techniques were used in the investigation of novel palladium complexes with
bioactive thiosemicarbazones derived from 5-nitrofurane or 5-nitrofurylacroleine. Sixteen ...
Synthesis and structural aspects of urea/dialkylamine inclusion compounds
(Kluwer Academic Publishers, 1995)
The synthesis and structural aspects of urea host-guest inclusion compounds containing linear secondary alkylamines (dibutyl-,dipentyl-, dihexyl-, dioctyl-) at 25°C are reported. Elemental analysis,13C CP-MAS NMR and1H-NMR ...
NMR as a tool for simultaneous study of diastereoisomeric inclusion complexes formed by racemic mixture of 4′-hydroxyflavanone and heptakis-(2,6-O-dimethyl)-β-cyclodextrin
(2010)
The complexes formed by (±)-4′-hydroxyflavanone (OHFL) and heptakis-(2,6-O-dimethyl)-β-cyclodextrin (DM-β-CD) were obtained using the racemic mixture of OHFL. These complexes were able to be studied due to their ...
Monte carlo simulation of epitaxial growth of gainassb films
(Universidad Nacional de Colombia Sede Medellín, 2014-10-24)
Material engineering finds an important support on simulation methods. The study of semiconductors growth techniques through simulation allows the determination of the influence of some growth parameters on the film ...
