Two very stable organic radical adducts 1 and 2 formed by an electron donor-acceptor system with bipolar charge transport behavior have been investigated. Both present the same electron donor moiety, 3,6-bis(N-carbazolyl)carbazole, and are distinguis

The tri-potassium salt of tris(2,3,5,6-tetrachloro-4- hydroxysulphonylphenyl)methyl radical, 3K + TSPTM 3-, is a good chemical sensor of the radical-scavenging activity of poly(phenols) in aqueous media. Its water solubility and its stability at all

Luciano ensaya la novela escénica: apariencia episódica y estructura unitaria de los Diálogos de los muertos

Autor: Lluís Juliá

Publikováno v: Emerita. 79:357-379

Lucian’s Dialogues of the Dead belong to a very specific genre and their order in manuscript transmission is very confused. For those reasons, they have been usually considered as individual scenes without interrelation to each other, apart from th
