The TLC data for different solutes chromatographed in methanol-acetone mobile phase on silica gel at 293 K are analysed by means of the theoretical equations discussed in the previous paper (1). This analysis shows that for the above systems the solute-solvent and solvent-solvent association and...
using the thin layer chromatography and different solvent systems in order to obtain the better resolution. The mobile phases that we used were represented by volumetric mixtures of methanol: chloroform: water (51:42:7), chloroform: methanol (7:3), chloroform: methanol (7:3) saturated with ...
These characteristic properties also demonstrated that the LLC/SWNTs systems took an advantage over the TLC/SWCNTs systems. Although using LLCs to align CNTs is a promising method to promote the application of CNTs, the direct incorporation of SWNTs into the LLCs...
Incorporation can be seen as a way of transferring energy to the bilayer molecule; as in many other physical and/or chemical systems, this energy could engender a sort of phase transition; (3) finally, after monitoring the insertion process when a given external voltage is applied until the ...

A proper mixing is very important for a better reaction, especially in multi-phase reaction systems to increase the interfacial area in the reactant mixture in order to enhance the mass transfer rate in the reactor. The commonly used reactor is the Stirred Tank Reactor (STR) because it has ...
Tandem MS systems have high sensitivity and they have been used mostly recently. When the sensitivity of LC-MS/MS was compared by considering the similar recovery values, HPLC-FD technique was better.Lastly, for the determination of AFM1 specie, two-dimensional TLC technique has high sensitivity...
as DCM slurry were applied to a column of 30 g silica and 12.5 mL fractions were eluted with 150 mL DCM, then 125 mL DCM: methanol 4:1 and finally with 150 mL DCM: methanol 2:1. Each fraction (1 uL) was run on TLC using DCM: methanol 2:1 as solvent. The major...
The results have been interpreted in terms of solute–solvent and solute–solute interactions in these systems. The Gibbs energies of activation of viscous flow per mole of solvent, Δμ1∘# and per mole of solute, Δμ2∘# were also calculated and discussed in terms of transition state ...
