ecletica-992	da Silveira Júnior, Pedro Belchior; Tiera, Vera Aparecida de Oliveira; Tiera, Marcio José	A fluorescence probe study of gemini surfactants in aqueous solution: a comparison between n-2-n and n-6-n series of the alkanediyl-a,w-bis (dimethylalkylammonium bromides)	2007	8	.pdf	application/pdf	3928	221	59	The presence of preaggregates in submicellar concentrations of dimeric surfactants has been suggested by Mathias et al. in a recent work using time resolved fluorescence spectroscopy[23], and thereafter their method was contested by Zana [24,25]. This behavior may be due to the increasing aggregation numbers (N ) with concentration and this has been observed for dimeric surfactants having short as well as longer spacer groups	cache/ecletica-992.pdf	txt/ecletica-992.txt
