Abstract
The Program evolved with time from ceramics, to synthesis and functionalization of nanoparticles (NPs), and followed by assembly the NPs into new complex materials. We will continue the research of controlled synthesis of materials, in particular, oxides materials with the functional properties originating from their specific structuring at the nano scale. In the forefront are the magnetic materials and their combinations with other materials assembled into multifunctional nanocomposites. Special attention will be given to syntheses of composite nanoparticles at interfaces where a monolayer of NPs is assembled at an interface while the surface chemical reaction takes place only on one side of the interface. The reactions include surface functionalization, deposition of layers and bonding with other NPs. Such approach should allow us to synthesize Janus NPs having two faces with different physical properties. The development of plate-like Janus NPs holds a large potential for a major breakthrough in the multifunctional nanohybrids with orientation-dependent physico-chemical properties, needed for the realization of magnetically (and electrically) switchable optics, chemical sensors, wireless signal transfer, and contactless valves/pumps in microfluidics. New bulk composites with periodically-structured nanoparticles inside a transparent polymer matrix will be synthesized using magnetically-directed assembly of colloidal magnetic NPs dispersed in monomer (e.g., MMA) followed with a rapid polymerization. For rapid polymerization to take place homogeneously across the suspension, a new method will be developed based on heating the magnetic NPs in an AC magnetic field. In parallel with the synthesis of new materials we develop knowledge related to their applications. The proof-of-the-concept research on the magneto-mechanical cancer treatment will be extended to entirely new concepts of therapy of neurodegenerative and cardiovascular diseases. With magneto-mechanical actuation mediated by anisotropic magnetic NPs we can disintegrate protein aggregates, e.g., large amyloid-β fibrils, which are the hallmark of neurodegeneration, such as Alzheimer’s disease. The anisotropic NPs will also be applied to deliver drugs and to magneto-mechanically assist disruption of the blood cloths for therapy of cardiovascular diseases. In front of our applications in technology will be a magnetically-mediated catalysis. Our new method based on selective heating of catalyst using an AC magnetic field holds large potential to improve selectivity of the catalytic processes (e.g., when thermolabile products are formed). In addition, it enables direct conversion of peak electrical power for production of chemicals (Power-to-Chemicals). New magnetically-recyclable catalysts will also be developed (e.g., based on surface frustrated Lewis pairs on AlF3 coatings) to be used in valorisation of wood biomass.
Significance for science
Accessibility to the appropriate material is frequently the main obstacle in the development of a new area of science and technology. The scientific principles governing the development in a certain area of science might frequently be well known; however, the development is limited by a lack of the appropriate synthesis methods needed for the preparation of the material required. In such a situation, knowledge enabling the synthesis of the required material can facilitate a burst of research and new products. A good example is ferromagnetic liquid crystals, the existence of which was predicted by Brochard and de Gennes already more than four decades ago, however, only our development of the synthesis of magnetic barium-hexaferrite (BHF) nanoplatelets (NPLs) enabled the first experimental evidence (Nature 2013), and, even more importantly, enabled further research and development of entirely new principles in physics and technology (10 articles, involving our group, have been already published related to properties and applications of the ferromagnetic liquids). Further research lead to development of ferromagnetic ferrofluids based on concentrated suspensions of the BHF NPLs in isotropic carrier liquids (Nature Comm. 2016), which will further broaden the initiated research on ferromagnetic liquids. The program is directed towards the synthesis of new, complex nanomaterials that have an exceptional potential for new breakthroughs in science, which will also lead to new technologies. We will make a significant advancement using our knowledge, related to the control of nanoparticles (NPs) surface properties and their assembly into in the nanocomposites, by extending our research to reactions at the interfaces. This will lead to the synthesis of magnetic Janus NPLs with different physical properties at different faces; thus showing an orientation-depended behaviours. This will lay the foundations for development of novel devices and sensors, e.g., miniature, all-optical and contactless rotation sensors, contactless valves/pumps and micro-motors for microfluidic systems, magnetometers and electric-field sensors for smart-grid and transportations-system applications, large-sensitive-area force sensors for robotic and bio-medical applications, and wireless signal-transmission systems for the moving parts in industrial and service robotics. All of these are needed for our future autonomous industry and transportation, smart houses and smart cities, for higher quality of life. Among the materials with exceptional potential for brake breakthroughs in mentioned fields we also have to mention composites with periodically-structured NPs inside the transparent polymer matrix prepared by magnetically-directed assembly. With polymerization of the suspensions of superparamagnetic colloidal particles in monomers, which essentially represent magnetically-tunable liquid crystals, new composites will be synthesized for applications in photonics. In certain areas of our research, the materials will be developed in parallel with new applications. Our new concept of magneto-mechanical cancer therapy will be extended to proof the entirely new therapy concepts of neurodegenerative diseases based on actuation of soft metter. Moreover, we will study also magneto-mechanically assisted breaking of blood cloths as a basis for treatment of cardiovascular diseases. In the fields of environmental, chemical and biotechnologies the new approach of magnetically-mediated catalysis will be developed based on selective heating of the catalyst with an alternating magnetic field (AMF). The heating with AFM is also central to our new approaches of direct conversion of electrical power for synthesis of chemicals (Power-to-Chemicals) and materials (Power-to-Materials). The mentioned new approach in applications of magnetic nanomaterials hold a large potential for initiating further interdisciplinary research in along the entire innovation chain from the materials to th
Significance for the country
A largest part of our research is targeted to making foundations for subsequent development of new products, technologies and services. The main research direction of the program is in the development of knowledge for the controlled synthesis of new complex materials and their use in biomedicine and different technologies. We intentionally develop only synthesis methods that are simple, do not require expensive equipment, and thus enable fast transfer to the mass production. Our research is thus increasingly important for Slovenian industry. Recently we have been involved in research of synthesis and final characterization of non-biological complex nanoparticles-based drugs in direct financing of a Sandoz Company Lek. A part of our research remains devoted to ceramics displaying a positive temperature coefficient of resistivity (PTCR) where we traditionally cooperate with the Stelem Company. To even further strengthen the transfer of our research results into practical use we recently established two spinout companies. Nanos Scientificae develops and markets materials based on magnetic NPs used in subsequent biomedical research and photonics. InoVine develops new technology based on our invention of a new method for sparkling wine production with rapid magnetic separation. The company employs researches and thus we contribute also to creation of new jobs. The program contributes to higher education and human resources development with four habilitated professors. The members of the program are involved in pedagogic process (on graduate and postgraduate level) at Faculty for Chemistry and Chemical Technology, University of Maribor, Faculty of Medicine, University of Maribor, at the International Postgraduate School of Jožef Stefan and at Faculty of Pharmacy, University of Ljubljana. In last 10 years we mentored 10 PhD students, who all sucessfuly finished their education, and numerous diploma and master works. Our formed PhD students have worked at renowened scientific organizations, e.g., ETH Zurich, EPFL Lausanne, Imperial College London (UK), University of California, Berkeley (USA), etc. Our research contributed to the development of medicine with supporting medical professionals with our expertise on nanoparticles, and with development of new materials to be used in medicine, e.g., magnetic nanoparticles for hyperthermia cancer treatment, fluorescent nanoparticles to be used as biomarkers, contribution to develppment of drugs. We also set a basis for new approach in cancer treatment based on magneto-mechanical actuation of anisotropic magnetic nanoparticles.  With our expertise on nanoparticles we also supported the nanotoxicology research, the important envernmental aspect of engineered-nanoparticles production. We contributed to the publication of more than 20 articles in the field of nanotoxicology (mainly in cooperation with Biotechnicl Faculty, University of Ljubljana). To ecology we also contributed with development of new materials for water remedition, e.g., magnetically-recycleble (foto)catalysts and adsorbents for heavy metals, and for development of catalysts for production of green chemicals, e.g., valorisation of wood biomass. We even contributed to arts.  We cooperated with the Art Academy, University of Ljubljana in development of new artistic techniques based on manipulation with a suspension of magnetic nanoparticles. With broad network of research cooperation worldwide we also contributed to access to foreign knowledge.
