(1992)Lifetimes of pyrene incorporated into large unilamellar vesicles of dipalmitoylphosphatidylcholine and dioctadecyldimethylammonium chloride increase when the temperature increases prior to the melting temperature of the ...
-
(1989)2,2′-Azobis-[2-amidinopropane] initiated lipid peroxidation of egg yolk phosphatydil choline liposomes was measured by oxygen uptake and the emitted visible luminescence. Lipid peroxidation involved a chain process (kinetic ...
-
(1989)The exchange between bromide and chloride counterions at the surfaces of dioctadecyldimethylammonium vesicles has been examined through fluorescence quenching experiments. The quenching of the fluorescence of vesicle-incorporated ...
-
(Universidad de Chile, 2005)Con el objetivo de contribuir al conocimiento del comportamiento básico de este tipo de compuestos y sus potenciales aplicaciones, en esta memoria se estudiaron las propiedades fisicoquímicas de soluciones acuosas de ...
-
(1988)The polymerization of methyl methacrylate photosensitized by benzion methyl ether over a wide range of initiator absorbances was investigated. Both the polymerization rate and the polymer molecular weight distribution are ...
-
(Universidad de Chile, 2016)En esta tesis se estudiaron tanto las características fisicoquímicas de los complejos de inclusión de derivados de ariloxazinonas y arilnaftoxazoles en ciclodextrinas y se determinaron los parámetros termodinámicos que ...
-
(2009)Detection of O2(1 g) emission, max = 1270 nm, following laser excitation and steady-state methodswere employed to measure the total reaction rate constant, kT, and the reactive reaction rate constant, kR, for the reaction ...
-
(The American Society of Photobiology, 2013)In this study, we report the synthesis and photochemical behavior of a new family of photoactive compounds to assess its potential as singlet oxygen (1O2) probes. The candidate dyads are composed by a 1O2 trap plus a ...
-
(1986)The photochemistry of alkyl pyruvates of the type CH3COCOOCHR2 has been examined in solution using a combination of product studies and laser flash photolysis techniques. The results indicate that the main reaction path ...
-
(1990)The photochemistry of ethyl esters of α-oxo-carboxylic acids of the type RCOCO2CH2CH3 was examined using a combination of steady state irradiation and laser flash photolysis techniques. The experimental results indicate ...
-
(1992)Nimodipine, a calcium antagonist belonging to the dihydropyridine family, produces a well‐defined polarographic peak due to the four‐electron reduction of the nitro group. This peak was used to track the photodecomposition ...
-
(Universidad de Chile, 2020)El oxígeno singulete (1O2) es una especie electrónicamente excitada del oxígeno molecular y altamente reactiva. Pertenece a la familia de las especies reactivas de oxígeno (ROS), protagonistas de diversos procesos fisiológicos ...
-
(Elsevier, 2006)A fluorescence method was employed to study the solubilizing interactions of several sucrose esters with Dioctadecyldimethylammonium chloride small unilamellar vesicles. In this paper we studied four different alkyl esters ...
-
(Elsevier, 2009-02)The solubilization of biological membranes by detergents has been used as amajor method for the isolation and purification of membrane proteins and other constituents. Considerable interest in this field has resulted ...
-
(ELSEVIER SCIENCE SA, 2004-12-01)Three lipid-soluble furan derivatives, 2,5-disubstituted with different n-alkyl chains, and a terminal trimethylammonium group were obtained by reaction of a metalated monoalkylfuran with alkyl dihalides under conditions ...
-
(1983)The photochemistry of several phenyl alkyl and p-anisyl alkyl ketones has been examined using laser flash photolysis and conventional quantum yield techniques. The methoxy-substituted ketones show higher activation energies ...
