متن کاملCationic gemini surfactants as pseudostationary phases in micellar electrokinetic chromatography. Part I: effect of head group.
Two cationic gemini surfactants with pyrrolidinium or alkyl ammonium head groups with but-2-yne spacers, but with the same length hydrocarbon chain have been characterized with respect to their aggregation behaviors and separation power as pseudostationary phases (PSPs) for micellar electrokinetic chromatography (MEKC). They were compared with a commonly used PSP, sodium dodecylsulfate (SDS). T...
متن کاملSilver Nanoparticles Stabilised by Cationic Gemini Surfactants with Variable Spacer Length.
The present study is focused on the synthesis and investigation of the physicochemical and biological properties of silver nanoparticles stabilized with a series of cationic gemini surfactants having a polymethylene spacer of variable length. UV-VIS spectroscopy, dynamic light scattering, scanning electron microscopy and zeta potential measurements were applied to provide physicochemical charac...
متن کاملGreen Synthesis, Molecular Characterization and Associative Behavior of Some Gemini Surfactants without a Spacer Group
A series of new gemini surfactants without a spacer group, disodium 2,3-dialkyl-1,2,3,4-butanetetracarboxylates, were synthesized in a green chemistry context minimizing the use of organic solvents and applying microwaves (MW) when activation energy was required. Once the desired architecture was confirmed by means of the nuclear magnetic resonance technique (¹H-NMR, ¹H-¹H COSY) for all the stu...
متن کاملThe microstructure of DNA-egg yolk phosphatidylcholine-gemini surfactants complexes: effect of the spacer length.
BACKGROUND The length of spacer of gemini surfactants affects the DNA packing in DNA-neutral phospholipid-gemini surfactant complexes. METHODS The microstructure of complexes DNA-egg yolk phosphatidylcholine (EYPC)-alkane-α,ω-diyl-bis(dodecyl\xaddimethylammonium bromides) (CnGS, spacer n=2-12, n is even) was studied using small angle X-ray diffraction. RESULTS At EYPC:CnGS=1:1 mol/mol, the ...
