  • Invited talks at Oxford University and Imperial College in United Kingdom.
  • Several invitations to the prestigious Gordon Research Conferences. The primary criteria for attendance at the Conference are scientific accomplishment and merit. Attendance is limited to about 100 participants from around the world. This is an expression of professional recognition by internationally renowned scientists.
  • Several US universities (Harvard, Rice, University of Florida, etc.) use one of Nikolo's papers describing the theory and application of ac susceptibility measurements (American J. Physics, 63, 57 (1995)), as a key reference in their advanced undergraduate labs. Some professors described it as “the clearest account of the measurement method available in the literature”. Many researchers have cited it as a key reference in their ac susceptometer design. Nikolo is considered an authority on ac susceptibility measurements. Googling “M. Nikolo, ac susceptibility” gives over 1200 results.
