Objective: Investigate the contributions of ion specific interactions to the balance of forces controlling aggregate structure.Responsibilities: - Synthesis of the series of cationic surfactants with given counterions and headgroup structures- Design and development of the lab experiments- Physico-chemical analysis of micellar solutions of synthesized amphiphiles- Data analysis (e.g. adaptation of the existing fitting model to fit the data)- Characterization of the… Show more Objective: Investigate the contributions of ion specific interactions to the balance of forces controlling aggregate structure.Responsibilities: - Synthesis of the series of cationic surfactants with given counterions and headgroup structures- Design and development of the lab experiments- Physico-chemical analysis of micellar solutions of synthesized amphiphiles- Data analysis (e.g. adaptation of the existing fitting model to fit the data)- Characterization of the interfacial properties of the aggregates in water in collaboration with other research teams- Crystallization and characterization of the amphiphiles by single-crystal X-ray diffraction- Examination of the impact of ion specific effects on the balance of forces that drives self-assembly process of amphiphile moleculesAchievements:- Development of the protocol, which allows to obtain the single crystals from hardly crystalized compound. This was a challenge in our lab for many years before- I demonstrated that changing the counterions of the surfactants we can obtain different rheological properties- I demonstrated the influence of ion specific effects on the self-assembly of cationic gemini surfactants. Summarized in thesis and publications- Combination of experimental and computational approaches- Thesis conclusion: I demonstrated that hydration free energy is the parameter, which has major effect of the ion specific effects Show less
