The optical properties of chiral centers used as tools for studying irreversible or reversible reactions of synthetic polymers in solution
Autor: Michel Vert, Eric Selegny
Publikováno v: Journal of Polymer Science: Polymer Symposia. 42:1239-1248
The optically active manifestations (ORD and CD) of asymmetric centers of synthetic macromolecules are discussed. Well known for conformational studies, they can also detect or give quantative information about the covalent or associative reactions o

Publikováno v: Journal of Membrane Science. 108:161-169
The non-isothermal facilitated transport of CO 2 through a sulfonic cation exchange membrane (Permion 5010) containing organic diamine counter-ion carrier (EDA) has been studied experimentally and confronted with a theoretical model based on the Nern

Active transport of protons and electrons driven by redox enzyme reactions via a cofactor shuttle (NADH/NAD), a model: Kinetics of activity and evolution of redox potential gradients
Autor: Eric Selegny, Jean-Claude Vincent, G. Demmano
Publikováno v: Bioelectrochemistry and Bioenergetics. 31:271-288
In order to explore the concept and kinetics of electron and proton transport induced by redox gradients, a model of active transport of protons and electrons through an artificial membrane was designed. The pump is based on two inverse redox reactio

Experimental procedure for a hydrogen peroxide assay based on the peroxidase-oxidase reaction
Autor: Eric Selegny, Jean-Claude Vincent, Gustave Demmano
Publikováno v: European journal of biochemistry. 238(3)
A low-cost assay method that is able to measure H2O2 concentrations as low as the nano-molar range is described. The assay solution contains NADH, horseradish peroxidase, and superoxide dismutase at PH 7.5. After the addition of the sample, the decre

Publikováno v: Die Makromolekulare Chemie. 176:709-728
Two poly(vinyl ketone)s, poly(methyl vinyl ketone) (PMVK) and poly(phenyl vinyl ketone) (PPVK), are isotacticly synthesized. The 1H-NMR spectra of these polymers and of the meso and racemic model dimers help to determine the percentage of isotactic d

Effect of nonelectrostatic interactions on the macromolecular behavior of polyelectrolyes. II. Influence of urea and dyes on the viscometric and optical behavior of PLL
Autor: Jacques Beaumais, Eric Selegny, J. C. Fenyo, Guy Muller
Publikováno v: Journal of Polymer Science: Polymer Chemistry Edition. 12:2671-2682
The effect of urea and of dyes on the viscometric behavior of aqueous solutions of PLL has been investigated. The compact structure, which is characteristic of PLL in pure water, is found to disappear progressively as the amount of urea is increased.
