Webmodified the equation and applied it to the mixed micelle system. The modified equation has been extensively used to analyze the partition phenomenon of solutes in binary mixed micelle systems [5, 6, 22, 23, 26-33]. The Markov chain (MC) model is an alternative to the SM model based on which the CMC of the mixed micelle can be estimated. WebI am a physical chemist and am fascinated by the origin of life. I think that an important step in life coming into existence is the coming together of the right molecules in complex structures. Similar structures can be used to extract molecules from wastewater in order to recycle them. For me it is very important that fundamental research can lead to useful …
