Interfacial properties of poly(maleic acid-alt-1-alkene) disodium salts at water/hydrocarbon interfaces
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-06-01)
The interfacial properties ofpoly(maleic acid-alt-1-alkene) disodium salts at hydrocarbon/water interfaces are determined. In all the studied systems, the interfacial tension decreases markedly with the polyelectrolyte ...
Solubilization of Alkylpyridinium Ions in Cationic Micelles: Effect of the Electrostatic Repulsion
(1993)
Binding constants of n-alkylpyridinium, CnPd+ (n = 10, 11, 12, 13, 14, and 16), to CTAX micelles, where X = Br− and Cl−, and to CTAOTOS were determined by ultrafiltration and a steady-state fluorescence method. These ...
Synthesis, physicochemical and photophysical characterization of 4-(1-Pyrenyl)-Butyl-α-d-mannopyranoside
(Sociedade Brasileira de Quimica, 2016)
Glycolipids are biomolecules composed of a lipid chain (lipophilic) and a monosaccharide or oligosaccharide as hydrophilic group. Their chemical structure and biological role make them undoubtedly good candidates for a ...
Zinc oxide/carboxylic acid lamellar structures
(2011)
Hybrid organic-inorganic semiconductor nanocomposites of layered zinc oxide/carboxylic acids were fabricated. Products are pure phases with structures constituted by double-layer sheets of the inorganic component sandwiched ...
Filtraciones en bypass gástrico resectivo por laparotomía en obesidad mórbida
(2012-02)
Background: Obesity is a severe disease whose prevalence continues to increase. Resective gastric bypass is one of the surgical procedures used in our center in patients with obesity, but like other techniques is not without ...
Tuning White Light Emission in Dinuclear Phenoxo Bridged DyIII Complexes
(American Chemical Society, 2019)
© 2019 American Chemical Society.A new series of dinuclear dysprosium(III) complexes, [Dy2(LCH3)2(NO3)2(MeOH)2] (I), [Dy2(LCH3)2(NO3)2(DMF)2]·2DMF (II), [Dy2(LCl)2(NO3)2(DMF)2]·2DMF (III), and [Dy2(LCH3O)2(NO3)2(DMF)2] ...
Photocatalytic thin films containing TiO2:N nanopowders obtained by the layer-by-layer self-assembling method
(Elsevier, 2012)
In this work, TiO2–N powders were synthesized by high-energy ball milling, using commercial titanium
dioxide (TiO2) in the anatase phase and urea to introduce nitrogen into TiO2 in order to enhance their
photocatalytic ...
Frequency of transferable multiple antibiotic resistance amongst coliform bacteria isolated from a treated sewage effluent in Antofagasta, Chile
(UNIV CATOLICA DE VALPARAISO, 2006-10-15)
Antibiotic-resistant coliform bacteria from raw and treated water from activated sludge of a sewage treatment plant were isolated on eosin methylene blue agar (EMB) plates in the separate presence of ampicillin, tetracycline, ...
Selective crystallization of calcium salts by poly (acrylate)-grafted chitosan
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-06-01)
The biopolymer chitosan was chemically modified by grafting polyacrylamide or polyacrylic acid in a homogeneous aqueous phase using potassium persulfate (KPS) as redox initiator system in the presence of N,N-methylene-bi ...
Polymer Precursors Effect in the Macromolecular Metal-Polymer on the Rh/RhO2/Rh(2)O(3)Phase Using Solvent-Less Synthesis and Its Photocatalytic Activity
(Springer, 2020)
A mixture of a nanostructured Rh/RhO(2)phase was easily obtained by thermally treating the macromolecular Chitosan center dot(RhCl3)(x)precursor, while the Rh/Rh(2)O(3)phase was obtained by pyrolyzing PSP-4-PVP center ...
