The experimental study of reverse micellar phase in AOT/ Heptane/ (Water or aqueous) as nano template

the experimental study of reverse micellar phase in aot/ heptane/ (water or aqueous) as nano template

in this paper electrical conductivity measurements and optical investigations takes place in aot/ heptane/ (water or aqueous) systems. the water in oil system prepared with adding water in 50% by weight of aot/ heptane solution.  in other systems instead of water, aqueous solutions of 1) zinc acetate and water 2) potassium hydroxide and water were used. in each phase, the trend of the electrica...

Comparison Between Aqueous and Nonaqueous AOT-Heptane Reverse Micelles Using Acridine Orange as Molecular Probe

Aqueous and nonaqueous AOT/n-heptane reverse micelles where characterized by UV-Visible and fluorescence spectroscopy of AO. The study shows the presence of the dimer in aqueous reverse micelles which is not present in the nonaqueous systems. It seems that there is a conversion of the dimer to monomer in the aqueous reverse micelles at high AOT concentration. In the nonaqueous systems, there is...

the effectiveness of strategy-based instruction in teaching english as a second or foreign language: a meta-analysis of experimental studies

a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...

Experimental Study of Phase Inversion in n-Butylacetate-Water, Kerosene-Water, and n-Heptane-Water Systems in a Rotating Disc Contactor Column

Water dynamics at the interface in AOT reverse micelles.

The orientational dynamics of water molecules at the interface in large Aerosol-OT (AOT) reverse micelles are investigated using ultrafast infrared spectroscopy of the OD stretch of dilute HOD in H(2)O. In large reverse micelles ( approximately 9 nm diameter or larger), a significant amount of the nanoscopic water is sufficiently distant from the interface that it displays bulk-like characteris...
