The self-assembly of novel Gemini surfactants with pyrrolidone head groups, N,N'-dialkyl-N,N'-di(ethyl-2-pyrrolidone) ethylenediamine (Di-C (n) P, where n = 6, 8, 10, 12), was studied systematically by employing UV-vis spectroscopy, fluorescence spec

In pure sodium deoxycholate (NaDC) dilute solution, the transverse relaxation times (T (2)) of nearly all proton signals of NaDC obey single-exponential decay, with exception for proton at 3-position (H3) that decays in a two-exponential manner. The

The mechanism of micelle formation of surfactants sodium dodecyl sulfate (SDS), n-hexyldecyltrimethylammonium bromide (CTAB) and Triton X-100 (TX-100) in heavy water solutions was studied by 1H NMR (chemical shift and line shape) and NMR self-diffusi
