After receiving the Krka Prize in 2019, for the study entitled “Coloidal silver in dental products”, students Laura Drasler and Ula Dragman, from the Vič High School, under the mentorship of prof. Alenke Mozer (Gim. Vič) and Anje Korent (IJS, K7), submitted the research paper for the GENIUS Olympiad 2020 competition. The submitted research paper has made it to the finals of the GENIUS Olympiad 2020. The research focuses on the study of the colloidal silver concentration in dental products such as toothpaste, mouthwash and toothbrush. Commercial products with silver content were purchased and studied by students on K7, IJS laboratories. https://geniusolympiad.org/index.html
Research article: A spark-plasma-sintering approach to the manufacture of anisotropic Nd-Fe-B permanent magnets. The research article addresses issues associated with the production of Nd-Fe-B permanent magnets. The shape of the magnet is limited to simple geometrical forms when the conventional sintering techniques are applied. This approach limits the desing freedom of electrical motors and generators and hinders the development of advanced energy-conversion technologies. The authors proposed a contemporary sintering technique, based on fast consolidation of a powder compact by means of electrical current, as an alternative solution for the manufacture of complex-shaped magnets. https://www.sciencedirect.com/science/article/pii/S0304885319335887

Liquid-Cell Transmission Electron Microscopy (LCTEM) is a method for studying the nucleation and growth of nanostructures either from solutions or during the electrodeposition, at the nanoscale and in real time. In the joint study between the researchers at the Department for Nanostructured Materials at Jožef Stefan Institute and National Institute of Chemistry we have shown that the radical-induced redox chemistry can be used to investigate various redox-driven dynamics for a wide range of functional nanomaterials, in situ, and under dynamic conditions by applying LCTEM. We successfully modelled radical-induced redox chemistry processes in LCTEM, including the complex kinetics of the radiolysis species and their influence on the redox chemistry of the materials under investigation. The results of this study were published in a highly ranked journal Chemical Science (IF = 9,5).
A facile method for the simultaneous recovery of rare-earth elements and transition metals from Nd–Fe–B magnets
Dr. Kristina Žagar Soderžnik, from the Department of Nanostructured Materials, appeared in the science-educational-documentary movie, Fire of Science (Ogenj znanosti). In the movie, in addition to prof. dr. Jadran Lenarčič, Director of the JSI and prof. dr. Igor Muševič, Head of the Department of Solid State Physics, answers questions about why society needs science, what is its significance and whether science is a privilege. The science-education movie was made as part of the 70th anniversary of the Jozef Stefan Institute. https://4d.rtvslo.si/arhiv/dokumentarni-filmi-in-oddaje-izobrazevalni-program/174661968
