1. Removal of inclusions and trace elements from Al-Mg-Si alloys using refining fluxeUroš Kovačec, Franc Zupanič, 2025, original scientific article Abstract: The cleanliness of aluminium alloys has a decisive effect on their properties and performance. In this work, the melts of several Al-Mg-Si alloys (6xxx series) were refined using rotary flux injection (RFI) of the salt fluxes in the industrial environment. A typical charge consisted of 25 % to 30 % external scrap, 45 % to 50 % internal scrap, and 20 % to 30 % primary aluminium. During injection, the entire melt volume was mixed uniformly. The melt was filtered using a porous ring filtration apparatus. The fraction and type of non-metallic inclusions were determined using light and scanning electron microscopy. The contents of alkali and alkaline-earth metals were determined using optical emission spectroscopy. The reduction of alkali and alkaline earth metals and the fraction of nonmetallic inclusions were used to evaluate the process efficiency and the flux selection for the regular production. An analysis of more than 100 industry charges confirmed that the flux selected after the experimental trials, consisting of a mixture of MgCl2, KCl, NaCl and CaF2, was effective in regular production.

4. Reconciling the Other : travelling objects and collaborative teachingMoe Iezaki, Magdalena Novotná, 2022, original scientific article Abstract: A collaborative art education project involving Japan and the Czech Republic focused on the enculturation processes experienced by two teachers and their students, how immersion in visual arts can contribute to cultural understanding and the reconciliation of two pedagogical approaches to art. This project also addressed this reconciliation with the unknowable ‘Other’ through the creation of artwork, ‘travelling objects’ and collaborative teaching. Outcomes include similarities between objects from the two countries and two pedagogical approaches and suggest that participants strived to reconcile the Other, thus creating a spatial and relational intermediate space by dealing with those objects and communicating together.

6. Adaptations in music lessons : inclusion of a student with autism spectrum disorderKatja Sevšek, Bojan Kovačič, 2025, independent scientific component part or a chapter in a monograph Abstract: The present research explores teaching adaptations in music education for students with Autism Spectrum Disorder (ASD) in mainstream elementary schools. We examined how teaching experience and exposure to students with ASD impact the use of inclusive strategies and teachers' self-assessed competence by conducting a structured survey of music teachers in Slovenian elementary schools. Results show that adaptation practices differ depending on teaching experience, with experienced teachers more likely to implement structured routines, quiet spaces, and environmental modifications. There is a moderate correlation between the frequency of adaptations used by teachers and their ability to identify ASD characteristics. The findings highlight the importance of practical experience and targeted training in fostering teachers' confidence and competence, as well as the need for ongoing professional development to create inclusive and supportive learning environments in music education.

7. The neobanks and sustainabilityAleksandra Amon, Timotej Jagrič, Žan Oplotnik, 2024, review article Abstract: The rise of fintech in the financial sector presents a transformative shift towards digitalisation and sustainability on a global scale, leveraging technologies like AI to minimise environmental footprint. Neobanks not only challenge traditional banking models but also offer innovative solutions that align with sustainable objectives. The purpose of this paper is to analyse the impact of neobanks on global sustainability from economic, environmental, and social points of view. A comprehensive literature review of existing literature and current sustainable practices of neobanks was conducted. Results reveal that neobanks significantly positively contribute towards environmental sustainability with reduced paper use and logistics requirements of banking services. By offering more accessible and affordable banking services they importantly contribute towards higher financial inclusion, and with innovative products towards more competitive and innovative financial markets. AI-based tools they employ are increasing financial literacy and social inclusion. This article also highlights concerns regarding electronic waste management, potential high energy consumption, required digital literacy and cybersecurity risks. In conclusion, despite the mentioned risks, neobanks importantly contribute to global sustainability in many ways and will even more in the future. These findings can help neobanks shape sustainable practices and guide policymaking, as well as spread awareness of the sustainable impact of banking services.

8. Microstructure and surface topography study of nanolayered TiAlN/CrN hard coatingPeter Panjan, Peter Gselman, Matjaž Panjan, Tonica Bončina, Aljaž Drnovšek, Mihaela Albu, Miha Čekada, Franc Zupanič, 2022, original scientific article Abstract: The microstructure and surface topography of PVD hard coatings are among the most
important properties, as they significantly determine their mechanical, tribological and other properties. In this study, we systematically analyzed the microstructure and topography of a TiAlN/CrN
nanolayer coating (NL-TiAlN/CrN), not only because such coatings possess better mechanical and
tribological properties than TiAlN and CrN monolayer coatings, mainly because the contours of the
individual layers, in the cross-sectional STEM or SEM images of such coatings, make it easier to
follow topographic and microstructural changes that occurred during its growth. We investigated
the effects of the substrate rotation modes on the microstructure and surface topography of the
NL-TiAlN/CrN coating, as well as on the periodicity of the nanolayer structure. The influence of the
substrate material and the ion etching methods were also studied, while special attention was given to
the interlayer roughness and influence of non-metallic inclusions in the steel substrates on the growth
of the coating. The topographical features of the NL-TiAlN/CrN coating surface are correlated with
the observations from the cross-sectional TEM and FIB analysis. Selected non-metallic inclusions,
covered by the NL-TiAlN/CrN coating, were prepared for SEM and STEM analyses by the focused
ion beam. The same inclusions were analyzed prior to and after deposition. We found that substrate
rotation modes substantially influence the microstructure, surface topography and periodicity of the
NL-TiAlN/CrN layer. Non-metallic inclusions in the substrates cause the formation of shallow craters
or protrusions, depending on their net removal rates during the substrate pretreatment (polishing
and ion etching), as compared to the matrix.
Keywords: magnetron sputtering, nanolayer hard coatings, growth defects, surface topography, interlayer roughness, non-metallic inclusion, focused ion beam (FIB), scanning electron microscopy (SEM), scanning transmission electron microscopy (STEM)

10. The role of communication skills in the development of digital literacy competences using the "DigInGreen"Mateja Forte, Matevž Obrecht, Bojana Slomšek Šlamberger, 2024, published scientific conference contribution Abstract: The paper deals with the field of developing communicationand digital literacy with the help of the lifelong learning model "DigInGreen" for all layers of modern society, including people with special needs. The aim of the authors is a targeted search for new solutions in the field of using digital learning and communication tools for the development of digital competences in the light of"Society 5.0". We focus on a unique way of connecting paradigms,such as: inclusive society, competences, digital, special needs, literacy and lifelong learning. We want to connect the thinking about the communicative ability, an indispensable part of which is an individual's digital literacy and point out,that the circumstances of living in a modern, but still partially exclusive society, limit the development of an individual's communicativeand digital literacy,due to a demonstrated special need or disability. We believe,that the activities we carry out,are a unique example of good practice, because they connect many scientific disciplines and fields into a modern concept of competence development without excluding or conditioning the end user. We combine the paradigms of logistics, informatics, statistics, social studies, linguistics and didactics. All the above and more represent the concept of "Society 5.0", which cannot exist as a scientific construct,if it does not consider the key aspect of one's own identification -social equality and the provision of equal opportunities.
