Highly coercive permanent Nd-Fe-B-based magnets were successfully developed from commercially available MQU-F rapidly quenched ribbons with optimized composition by wet coating with DyF3 in isopropanol and subsequent spark plasma sintering and heat-treatment. Highest HCi enhancement was obtained at 2.2 wt.% Dy-fraction, i.e. from 1580 to 2025 kA/m, which is 25 % improvement. When more than 3 wt.% of Dy was added, the coercivity enhancement started to decrease, whereas at 4.8 wt.% the coercivity of as-sintered magnet was lower than it was for non-coated one and it was further decreasing with annealing time.

COBISS.SI-ID: 27115815In collaboration with company VARSI we continued development of special varistors for overvoltage protection of renewable energy systems (solar panels and wind turbine generators). The result is new types of varistors with high stability under dc field for operation under harsh climate conditions (temperature, humidity).
F.13 Development of new production methods and tools or processes
COBISS.SI-ID: 26718247Up to date three meteorites have been found on the territory of Slovenia, one stony and two iron types. The highly conserved stone meteorite named after the location Jezersko has recently joined to the collection of Slovenian meteorites. The detailed studies of the meteorite Jezersko, which were performed jointly at the Jozef Stefan Institute, Geological Survey of Slovenia, Faculty of Natural Sciences and the Museum for Natural History of Slovenia offers us an unique opportunity for in-depth understanding of the origin and evolution of our solar system in the last ~ 4.6 billion years. Meteorite Jezersko was registered into the database of all known meteorites in Lunar and Planetary Institute (Meteoritical Bulletin Database).
