Separation Science and Technology for Energy Applications symposia focus on key separations in developing energy-efficient processes and sustainable energy resources and systems. The conferences are held biennially and attract international participation. Our venue for the 2018 meeting is the Park Vista Hotel in Gatlinburg, Tennessee. Oral presentations are conducted without concurrent sessions to facilitate cross–discipline discussion among experts in various specialties of separation science. A poster session is a featured event and prizes are awarded for outstanding student contributions. The SST Program Committee announces a Call for Abstracts in the spring of each symposium year and seeks papers that illustrate new ideas, describe novel applications, identify newly recognized needs, and/or generate lively technical discussions on topics of separation science. Authors of both oral or poster presentations are encouraged to submit manuscripts for publication in a special issue of the refereed journal Separation Science and Technology.
