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 鈥渢he clearest account of the measurement method available in the literature鈥�. Many researchers have cited it as a key reference in their ac susceptometer design. Nikolo is considered an authority on ac susceptibility measurements. Googling 鈥淢. Nikolo, ac susceptibility鈥� gives over 1200 results.
