ABSTRACT. The solid charge transfer (CT) complexes of fluorescein (Flu) with definite acceptors (tetrafluoro para benzoquinone (Fla); 7,7,8,8-tetracyanoquinodimethane (TCNQ); 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) and iodine) were prepared. Several characteristic analytic procedures such as transmission (FT-IR), diffuse reflectance, UV-Vis absorption, cyclic voltammetry used to determine...

A partir de la comparación sus respectivos manifiestos, este artículo analiza las similitudes y diferencias más relevantes entre figuras Thomas Munk/Recycler Theodore Kaczynski/Unabomber, el referente real en que se inspira terrorista antitecnológico El camino Ida (2013) Ricardo Piglia. objetivo es averiguar qué aspectos transforma Piglia ideas Kaczynski cuáles son los alcances políticos del pa...

Sulfur doped titanium dioxide anatase nano-photocatalyst with different copper loadings (5, 10, 15, and 20 w/w %) was synthesized by hydrothermal method. The fabricated nanocatalysts were found to have high surface area, high aspect ratio, good surface morphology and high metals dispersion. The synthesized nanocatalysts were characterized by X-ray powder diffraction (XRD), Scanning electron mic...

A simulation model of light partitioning in horizontally homogeneous multispecies canopies is proposed. The model is based on the Kubelka–Munk equations (KM) applied to a mixture of N vegetation components. Only two hemispherical fluxes, i.e. downwards and upwards, are considered. The exact solution of KM equations was then simplified in such a way that the model can be easily extended to multi...
