(241c) From Multi-Scale Models to New Surface-Active Chemicals

Several energy-related advanced technologies rely on the control of interfacial phenomena. For example, long-term carbon sequestration in oceanic deposits could be achieved by properly tailoring growth and thermodynamic stability of clathrate hydrates, while manipulating interfacial tension is relevant for nano-scale materials synthesis and assembly. Sustainable development requires new green, bioderived, and environmentally friendly compounds for these, and other applications.

Our group has investigated structure-performance relations for surfactants used to control growth and agglomeration of hydrates, as well as to lower the interfacial tension between water and a variety of hydrocarbons. We will present here the lessons learned, towards developing a roadmap for the development of new green surface-active chemicals.
