This talk will address a range of issues related to pinning strategies in HTS. Both core pinning and magnetic pinning will be covered, as well as the possibility of including both these mechanisms together. The different aspects of the nanomaterials engineering to be considered include the control of chemical compatibility, and the size, geometry, orientation, distribution and population density of the second phases. Also, the suitability of the different methods for in-situ versus ex-situ processing will be considered, as well as potential issues for moving from lab-scale to commercial length samples. New data using pinning additives with very high performance will be used to illustrate the points to be covered.
