A selection of papers from the 8th Mechanical and Electromagnetic Effects in Superconductors (MEM16) workshop will be published in a Special Issue of Superconductor Science and Technology:

http://iopscience.iop.org/0953-2048/focus/Focus-on-selected-work-from-MEM16

Our aim for this special issue is to showcase the high quality, internationally competitive and cutting-edge work going on in this area. Papers will be within the scope of the workshop, and the journal, but do not need to directly reflect presentations given by the authors. All papers submitted will be subject to full peer review and must meet SUST's high editorial standards to be accepted for publication.
