This international journal publishes timely research on preparative separation processes and theoretical contributions to the field of separation science. We welcome papers on the following topics with applications across environmental sustainability, energy production, water treatment, and biotechnology: • adsorption/absorption • bioseparations • centrifugation • crystallization • distillation • electrically/magnetically driven separations • flocculation • extraction • membrane processes • precipitation • reactive separations The journal is also interested in publishing papers on continuous separations, hybrid processes, and carbon capture. Numerical studies must highlight the broad applicability of the results beyond the system studied. The journal does not publish analytical separation papers unless they contain new fundamental contributions to the field of separation science. Separation requires a selective transfer (i.e. transferring one substance while rejecting another). Simply describing the transferring of one substance from phase A to phase B is not a separation. If selectivity is not demonstrated (or has already been demonstrated) the paper will not be considered for publication. Peer Review Policy All submitted manuscripts are subject to initial appraisal by the Editorial Board, and, if found suitable for further consideration, to peer review by independent and anonymous expert referees. All peer review is single-blind and submission is online via ScholarOne Manuscripts.
