06 Oct: Pilot Action for Securing a Sustainable European Next Generation of Efficient RE-free magnets, H2020-SC5-2020-2
PASSENGER proposes improved strontium ferrite (Sr-ferrite) and a Manganese-Aluminum-Carbon (MnAlC) alloy as a substitute to guarantee a sustainable production of permanent magnets in Europe: an alternative without critical raw elements, based on resources that are widely available in Europe, with enough research to provide a solid base for a successful transition from the lab to the industrial production in our Pilot Plants. The project mission is to contribute to a green, sustainable Europe by developing an alternative to raw materials in the construction of permanent magnets and testing their performance in the electromobility sector. The project started in 2021 and will be finished in 2025. Currently the project is in the phase of fabrication if innovative materials for permanent magnets.

Prof. Dr. Slavko Bernik and Doc. Dr. Matejka Podlogar, in collaboration with researchers from the Shanghai Institute of Ceramics, Chinese Academy of Science, published an article in the journal ACS Applied Materials & Interfaces (IF 9.229) in which they report on a novel type of sustainable ZnO-based varistor ceramic that is based on Cr2O3 as varistor former and oxides of Ca, Co and Sb as the performance enhancers. The varistor ceramics ZnO-Cr2O3 are distinguished by an ultrahigh coefficient of nonlinearity a, a wide range of breakdown voltage EB and a very low leakage current IL. Compared to previously known ZnO-based varistor ceramics, the novel ceramics do not contain highly volatile Bi2O3, expensive rare earth elements (Pr6O11) or toxic V2O5, and the microstructure is practically single-phase. The formation mechanism of electrostatic Schottky barriers at the grain boundaries of ZnO with the addition of Cr2O3, which are the reason for the varistor…

New publication: Triggering the Aqueous Interparticle Association of γ‒Al2O3 Hierarchical Assemblies Using Divalent Cations and Cellulose Nanofibers. We successfully prepared stable aqueous suspensions, containing hierarchically assembled, mesoporous γ‒Al2O3 particles with high surface area. Addition of divalent cations such as Mg2+ or Ca2+ or cellulose nanofibers triggered a formation of various interparticle associations, which hindered or even prevented sedimentation. Preparation of such suspensions is especially important for preparation of advanced, porous ceramic materials relevant in catalysis and adsorption. The work was published in the leading scientific publication dealing with ceramic materials Journal of the European Ceramic Society.
04 Sep: NEW ARTICLE: Green Chemistry- Hierarchical Ru-bearing alumina/magnetic iron-oxide composite for the magnetically heated hydrogenation of furfural
Andraž Kocjan was involved in an interdisciplinary research directed by Sašo Gyergyek and Darko Makovec from the Department for Materials Synthesis and from the Department of Nanostructured Materials in a collaboration with researchers from the Department of Catalysis and Reaction Engineering of the National Institute of Chemistry. The work was published in the renowned scientific journal Green Chemistry, entitled Hierarchical Ru-bearing Alumina/Magnetic Iron-Oxide Composite for the Magnetically Heated Hydrogenation of Furfural. The paper demonstrates application of magnetic heating of nanoparticles in AC-field to drive chemical reaction. The authors showed that conversion of furfural to furfuryl alcohol over the catalyst in the same time interval reached 95% when “targeted” heating by AC magnetic field was used, but only 63% when conventional heating was applied. They were the first to show that a well-designed hierarchical composite (UK patent) can simultaneously serve as a catalyst and heat source to drive a technologically important…

13 Mar: NEW PUBLICATION; A spark-plasma-sintering approach to the manufacture of anisotropic Nd-Fe-B permanent magnets.
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

26 Feb: Awarded outside front cover, an art work representing the radical-induced redox chemistry inside the LCTEM
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).

Prof. Dr. Spomenka Kobe is the recipient of the prestigious »Frey Award for Leadership in development new technologies that contribute to global sustainable development in the environment, economy, and social points of view.” The summit honored the 2019 STARS of sustainable science, technology, and innovation and was divided into ten parallel Symposia devoted to the awardees. One of them was the “Kobe International Symposium on Science of Innovative and Sustainable Alloys and Magnets (SISAM),” where the world-leading scientists from the field of magnets and complex alloys presented the latest achievements in the field. Frey Award is granted to scientists, economists, and politicians. So far, the only awarded Slovene was a commissioner for science and later for environment Dr. Janez Potočnik. https://www.ijs.si/ijsw/IJS
28 Oct: Dr. Nina Kostevšek was awarded the Wüthrich International Young Star Award for the outstanding performances during the early career stages; SIPS 2019
Sustainable Industrial Processing Summit (SIPS 2019) took place in Cyprus from 23th to 26th of October 2019. Dr. Nina Kostevšek from the Department of nanostructured materials was awarded the Wüthrich International Young Star Award for the outstanding performances during the early career stages. This award has been established in honour of the distinguished work and lifetime achievements of 2002 Nobel Laureate in Chemistry, Prof. Kurt Wüthrich, who is known for developing the NMR method for studying macrobiological molecules. Dr. Nina Kostevšek presented work on the development of new nanoparticle-based contrast agents for magnetic resonance imaging.
24 Oct: Second place at Young researchers competition; 27 ICM&T, Portorož, Slovenia (16.-18.10.2019)
27th International Conference on Materials and Technology (27 ICM&T) took place in Portorož from 16th to 18th October 2019. In scope of the conference Young researchers competition was organized. The international committee awarded Hermina Hudelja from K7 with excellent second place for the talk entiteled: “Feather-light, cellulose-nanofiber-reinforced γ˗Al2O3 foams”.
Research article: Multicomponent permanent magnets for enhanced electrical device efficiency. We presented an innovative approach for improving the efficiency of permanent magnets which consequently improve the efficieny of electro-mechanical devices, such as electric motors and wind turbines. The research is based on results of simulations that predicted the benefits of using magnets containing regions with different magnetic properties. The proposed approach allows us to minimize the use of expensive and critical heavy-rare-earth elements dysprosium and terbium. https://www.sciencedirect.com/science/article/pii/S0304885319308170
On September 16, 2019, the fourth Scientific Slam took place at the ZRC Atrium. This year’s slam was held as part of the Cutting Edge 2019 conference.
