Robin Benedix received the Young Scientist Award for his outstanding master's thesis entitled: "CO2-Switchable Additive and Surfactants". "In his very detailed and systematic work on the characterization and application of the CO2-switchable additive N,N,N,N-tetramethyl-1,4-butanediamine and CO2-switchable "tail surfactants" using physico-chemical methods to determine surface tension and foam analysis, Mr. Benedix was able to show that surface properties, foam formation and foam stability can be changed by changing the additive with CO2 as a trigger. He also found a surfactant that has promising switchable and foaming properties. This work provides valuable insights into foam control in many large-scale applications and how to avoid the use of defoamers or antifoam agents that render surfactant solutions unusable."
