in this paper we study the concept of ph-biatness ofa banach algebra a, where ph is a continuous homomorphism on a.we prove that if ph is a continuous epimorphism on a and a hasa bounded approximate identity and a is ph- biat, then a is ph-amenable. in the case where ph is an isomorphism on a we showthat the ph- amenability of a implies its ph-biatness.
We have studied the micellization of surfactants SDS, CTAB and tweens-80 using a series of Ethylene glycol/water and formamide/water mixed solvents using surface tension, viscosity and conductance measurements. The results are compared with those reported in pure water for the same surfactants. The critical micelle concentration (cmc) shifts to lower values upon increasing the ratio of Ethylene...
Surfactants have the special ability to interact with the lipid bilayer of cell membranes. The red blood cell is one of the most used cellular membrane models to study the mechanisms underlying surfactant – induced osmotic cell resistance.The aim of this study is the evaluation of the effect of the prepared surfactants on red blood cells (RBC) as a model for biological membranes. Also, in this ...
The aggregation behavior of the ionic liquid (IL) 1-alkyl-3-methylimidazolium chloride with different alkyl chain lengths in a deep eutectic solvent (DES, composed of choline chloride and glycerol in a 1 : 2 mole ratio) was studied for the first time. The critical micellar concentration, micellar size and intermolecular interactions in IL/DES solutions were investigated by different techniques ...
