The research group at MagnetoCat SL (Alicante, Spain) published a fundamental theoretical work on magnetism in heterogeneous catalysis in ACS Catalysis. The group, composed by Ph.D. student Miss Chiara Biz, Dr. Mauro Fianchini and Dr. Jose Gracia, laid out a complex and comprehensive theoretical treatment linking electronic spin, magnetism and heterogeneous catalysis. This treatment concerns the behavior of correlated electrons in solids and the quantum mechanical "tricks" they implement to avoid each other while balancing repulsions and attractions.
