Biofilms – highly organised microbial communities – are often the hidden cause of recurrent infections in humans and animals, as well as contamination in food and pharmaceutical production. As these communities grow into 3D structures, microscopy is becoming increasingly important for their investigation, while imaging data processing requires multidisciplinary expertise. At the IJS, through collaboration between three departments (Biotechnology – B3, Knowledge Technologies – E8 and Condensed Matter Physics – F5), we have developed a new tool for analysing biofilm images called MicroICS, currently the only tool that combines analysis of confocal fluorescence images of biofilms with machine learning. It consists of three modules: the first converts images into quantitative structural features; in the second, we train models to understand how these features relate to the biological context; and in the third, we use the trained models to predict and classify new images. We have published an article on its development and functionalities in the journal npj Biofilms and Microbiomes. |
Sana Saeed from the Department for Nanostructured Materials at the Jožef Stefan Institute received the Best Poster Award at the CAMD Summer School 2026, held from 16 to 21 August 2026. Her poster, “Ab-initio and STM Investigation of the Nd₂Fe₁₄B Surface,” presented a combined experimental and computational study of the (001) surface of neodymium–iron–boron, an important material for high-performance permanent magnets. Using scanning tunneling microscopy, low-energy electron diffraction, and density functional theory simulations, the research identified an ordered surface reconstruction with a periodicity of 12.41 Å. The agreement between experimental and simulated STM images supported a reconstructed Nd-rich surface model. The work was carried out in collaboration with researchers from the Institute Jean Lamour in Nancy, France. This award recognizes the scientific quality, relevance, and presentation of the research and strengthens the international visibility of materials research conducted at the Jožef Stefan Institute. |
The Jožef Stefan Institute, as the lead partner, has secured the SMARTFACT programme, bringing together 17 research and industrial partners to develop more efficient, flexible and sustainable manufacturing. Research teams, system integrators and end users will jointly develop and validate solutions in real industrial environments. The programme comprises four thematic pillars: AI-supported process control, robotics of the future, laser processing for electronics, and plasma technologies. Activities will progress from industrial research at TRL 3–4 to prototype development and demonstrations at TRL 5–6. Expected results include self-learning manufacturing monitoring, energy-efficient production scheduling, automated quality inspection using computer vision, adaptable robotic systems, advanced laser processing and thermochromic sensors. SMARTFACT will contribute to higher productivity, improved quality, greater energy efficiency and the competitiveness of Slovenian industry. |
Researchers from the Electronic Ceramics Department at the Jožef Stefan Institute Ivana Goričan, Nejc Suban, Silvo Drnovšek, Matej Šadl and Hana Uršič, together with colleagues from Luxembourg and France, have published an article in Nature Communications Tunable electrocaloric effect in lead scandium tantalate through calcium doping. The study shows that calcium doping of lead scandium tantalate with a highly ordered B-site cation arrangement in the perovskite structure enables precise tuning of its phase transitions and electrocaloric response. The results reveal the emergence of an intermediate antiferroelectric phase and demonstrate an electrocaloric temperature change of about 2 K over a broad temperature range from 263 K to 353 K. These findings open new possibilities for cascaded electrocaloric cooling devices with extended operating ranges, including below the freezing point of water. |
