Why Is CO2 so soluble in imidazolium-based ionic liquids?

Abstract: Experimental and molecular modeling studies are conducted to investigate the underlying mechanisms for the high solubility of CO2 in imidazolium-based ionic liquids. CO2 absorption isotherms at 10, 25, and 50 °C are reported for six different ionic liquids formed by pairing three different anions with two cations that differ only in the nature of the “acidic” site at the 2-position on the imidazolium ring. Molecular dynamics simulations of these two cations paired with hexafluorophosphate in the pure state and mixed with CO2 are also described. Both the experimental and the simulation results indicate that the anion has the greatest impact on the solubility of CO2. Experimentally, it is found that the bis(trifluoromethylsulfonyl)imide anion has the greatest affinity for CO2, while there is little difference in CO2 solubility between ionic liquids having the tetrafluoroborate or hexafluorophosphate anion. The simulations show strong organization of CO2 about hexafluorophosphate anions, but only small diffe...

What do proactive people do? a longitudinal model linking proactive personality and career success

Abstract: We developed and tested a model linking proactive personality and career success through a set of four behavioral and cognitive mediators. A 2-year longitudinal design with data from a sample of 180 full-time employees and their supervisors was used. Results from structural equation modeling showed that proactive personality measured at Time 1 was positively related to innovation, political knowledge, and career initiative, but not voice; all measured at Time 2. Innovation, political knowledge, and career initiative in turn had positive relationships with career progression (salary growth and the number of promotions during the previous 2 years) and career satisfaction. Interestingly, voice had a negative relationship with career progression. We discuss practical implications and future research directions for proactive personality, extra-role behavior, and careers.
