Prof Annalisa Chiocchetti – Seminar Precision medicine is a groundbreaking approach to disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle for each person. This method stands in contrast to the traditional one-size-fits-all approach to medicine, where treatments and medications are developed with the average patient in mind. Nevertheless, we are far from it, and continued research, investment in healthcare infrastructure and policies are essential for realizing the full potential of this approach. This will take a long time and will not be achievable by 2030 as initially hoped. Great efforts have been undertaken to identify alternative approaches. One, involves organ on chip technology, that allows to model individual variability on a small 3D cell culturing platform. Will this be the answer to the huge unmet clinical need of selecting the right drug for the right patient? A tentative response in this lecture. Prof…
With the final INSPIRES project (EIT RawMaterials) meeting, the members of the Nanostructured Materials Department (Dr. Benjamin Podmiljšak, Dr. Tomaž Tomše, and Prof. Dr. Spomenka Kobe) in the consortium of 11 partners reported on the achieved goals. The INSPIRES project in the RIS Slovenia region has demonstrated a successful example of a circular economy without waste. Through radical eco-innovations in the recycling of permanent magnets, with a focus on the easily accessible resource of motors in household appliances, we have developed new automated processes for dismantling waste appliances and recovering magnets from them. We have established recycling methods and tested new circular economy pathways with key industrial partners within the region (Kolektor, Gorenje, Domel, ZEOS, Surovina). We have analyzed their sustainable performance in terms of economic and environmentally sound life cycles. Knowledge and technologies from non-RIS regions (recycling technology was provided by the German partner University of Pforzheim) contributed to…
RE-ENGINEERING PERMANENT MAGNETS FOR THE GREEN TRANSITION: EU PROJECT GREENE KICKS OFF Bohinj, Slovenia: On 4th and 5th June, a consortium of 15 European partners led by the Slovenian Jožef Stefan Institute kicked off GREENE, short for SINGLE-GRAIN RE-ENGINEERED Nd-Fe-B PERMANENT MAGNETS, an EU project with a funding of €8 million. Over a four-year period, partners will develop high-energy Nd-Fe-B based magnets, innovatively re-engineering them at the single grain level to minimize the overall Rare Earth (RE) content, thus reducing environmental impact and supply dependencies for these critical raw materials. Rare-earth element (REE) permanent magnets based on Neodymium Iron Boron (Nd-Fe-B) are vital components of high-tech products enabling a green energy future, like e-vehicles and wind turbines. With the advancement of the green transition, magnet demand is increasing drastically – supply, however, is under threat. The EU is dependent on imports, mainly from China, and geopolitical tensions, environmental issues connected…

Members of the Department for Nanostructured Materials Monika Kušter, dr. Zoran Samardžija, dr. Matej Komelj, dr. Sorour Semsari Parapari, dr. Matejka Podlogar, prof. dr. Jean-Marie Dubois and prof. dr. Sašo Šturm and an associate of the Department of Surface Engineering prof. dr. Janez Kovač published in a journal Crystals a study entitled: “Impact Of Tuned Oxidation on the Surface Energy of Sintered Samples Produced from Atomised B-Doped Al-Cu-Fe Quasicrystalline Powders”. In the article, we investigated the dynamics of the surface-energy changes on a boron-doped quasicrystalline AlCuFe material. The results of the study contribute to a broader insight into a quasicrystalline-material surface-energy controlled change under atmospheric conditions, as a result of the controlled oxide-layer growth. The results indicate the possibility of further optimization, i.e. engineering of quasicrystalline surfaces, which enables their applicative use in various composite systems strengthened by a quasicrystalline phase. The editors chose the article and graphical abstract for…
The Jean-Marie Dubois Prize will be awarded this year to Prof Dr. Michael Baake, a German mathematician and theoretical physicist working at the University of Bielefeld. The prize is named after our colleague from K7 and is administered by the State University of Iowa, USA, to “recognize important, sustained research on any aspect of quasicrystals within the 10 years preceding the award”.

Thiel, who pioneered research on the surface physics and chemistry of quasicrystals in close collaboration with JM Dubois. Together, they led an international laboratory between Ames Laboratories and the CNRS to promote the development of the applied physics of these new materials. Today, a similar binational initiative is active between the JSI and the CNRS, focusing on complex alloys, in line with a long-standing collaboration on…
Zdravljenje je vedno najbolj učinkovito, če se lahko bolezni lotimo kar najbolj neposredno, pri samem viru težav. A do vira pogosto sploh ni lahko priti. Denimo, če govorimo o okvarjenem genu, ki bi ga morda želeli utišati, da ne bi več povzročal težav. Področje tovrstnih genskih terapij daje v zadnjem času že zelo spodbudne rezultate in vanj so seveda usmerjeni številni raziskovalni napori. Prav tako zahtevno se je, po drugi strani, prebiti do bolj odmaknjenih tumorjev, ki se tako zlahka izmaknejo terapiji, za katero pa vemo, da ima celo paleto škodljivih stranskih učinkov. Naj gre torej za takšno ali drugačno zdravljenje, ključno vprašanje vsekakor je, kako spraviti pravo učinkovino na pravo mesto. Da bi bil ta transport učinkovin še povsem biorazgradljiv, dr. Nina Kostevšek z odseka za nanostrukturne materiale Instituta “Jožef Stefan” raziskuje možnosti uporabe membran rdečih krvnih celic. https://365.rtvslo.si/arhiv/podobe-znanja/174962029
Prostorsko-svetlobno instalacijo sestavlja niz kinetičnih objektov, ki so nastali na podlagi fizikalnih vizualizacij magnetnih skirmionov, toplotnih kvazidelcev v obliki vrtincev v strukturi magnetnih materialov, ki lahko prenašajo informacije in imajo specifični tehnični potencial v razvoju napredne svetlobne in ekološko odgovorne tehnologije. Kinetični objekti variirajo v obliki, saj ne poskušajo objektivno razlagati in posnemati znanstvenih vizualizacij, ampak interpretirajo različne tipe modelizacij (strukture, diagrame, sheme, tridimenzionalne ponazoritve gibanja delcev ali magnetnih silnic). Formalni rezultat te umetniške interpretacije je prej fantazmagoričen kot verističen in ta vidik je poudarjen z dodatnimi učinki kinetičnega vrtenja, svetlobnimi in video projekcijami, ki skupaj ustvarjajo fiktivno prostorsko krajino v gibanju. Kinetična svetlobno-prostorska instalacija deluje kot zaznavni (optični in telesni) eksperiment in z izzivanjem ustaljenih percepcijskih navad širi kognitivno izkušnjo gledalca. Projekt stremi k prepletanju estetske izkušnje s širšimi vprašanji o materialnem ustroju našega vesolja na subatomski ravni, sprašuje o subjektivnih načinih razumevanja in doživljanja narave fizikalne stvarnosti na eni strani…

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.
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…

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).

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
