About the validity of complex mass scheme for the Δ resonance and higher energy region approaches

Autor: Barbero, César Alberto, Mariano, Alejandro Edgardo

It is a well known fact that when a resonance (R) is produced and decays, its unperturbed propagator will be singular at p2 mR = 2 when it appears in an s-type Feynman pole graph. Nevertheless this is not a problem, since i must be dressed by the suc

The quasielastic charged current (CCQE) νen→e⎯pνen→e−p scattering is the dominant mechanism to detect appearance of a νe in an almost νμ flux at the 1 GeV scale. Actual experiments show a precision below 1% and between less known backgro

We report the preliminary result of an exact calculation of the asymmetry parameter, aΛ, in the nonmesonic hypernuclear decay, based on a one-meson-exchange (OME) model. For the case of Λ 5He and including one-pion-exchange only, the result is show

Development of micropatterning polyimide films for enhanced antifouling and antibacterial properties

Autor: Cesar A. Barbero, Diego F. Acevedo, Emma Antonia Cuello, Lucinda Emma Mulko, Edith Inés Yslas

A commercial biomedical Polyimide (PI) film was topographically and chemically modified by generating micrometric periodic arrays of lines using Direct Laser Interference Patterning (DLIP) in order to improve antifouling and antibacterial properties.

A colorimetric iron sensor based on the partition of phenanthroline complexes into polymeric hydrogels. Combinatorial synthesis and high throughput screening of the hydrogel matrix

Autor: Maria C. Miras, María Victoria Martinez, Claudia R. Rivarola, Cesar Alberto Barbero

Publikováno v: Sensors and Actuators B: Chemical. 241:19-32

A combinatorial library of hydrogels is produced by radical polymerization and tested for retention of iron (II) complexes, using a simple colorimetric high throughput screening (HTS). Six acrylamide monomers are used to produce a library of 21 cross
