For the 27th time, the Jožef Stefan Institute awarded the Golden Emblem Prize to authors of doctoral theses with the highest impact in Slovenia and abroad, which were defended in the Republic of Slovenia in the past three years. This year, the Golden Emblem was awarded to dr. Primož Koželj and dr. Victor Vega Mayoral. Dr. Koželj received the Golden Emblem for the high impact of his dissertation “Physical Properties of High-Entropy Alloys and their Comparison to Complex Intermetallics” and dr. Mayoral for his dissertation “Photophysics of transition metal dichalcogenides obtained from liquid phase exfoliation”. The Golden Emblems were awarded on March 27, 2019, in the Cankarjev dom conference centre as part of the celebration in honour of 70 years of the Jožef Stefan Institute. Keynote speakers were the director of JSI, prof. dr. Jadran Lenarčič, and president of the Republic of Slovenia, Mr. Marjan Šarec.

The article Mosaics of topological defects in micropatterned liquid crystal textures written by Dae Seok Kim and Dong Ki Yoon from the KAIST Institute in South Korea, Simon Čopar from the Faculty of Mathematics and Physics, University of Ljubljana, and Uroš Tkalec, associate of the Condensed Matter Physics Department at the Jožef Stefan Institute, was published in the Science Advances journal. The article presents an experimental method of controlled creation of micropatterned topological defects in thin layers of nematic and smectic phases in liquid crystals using micropatterned surfaces. The created patterns are very robust, colourful and responsive to the changes in the thickness of the layer and the temperature. The patterns can cover several square centimetres of the surface, follow the symmetrical rules on topological charge conservation and look like ceramic or glass mosaics or stained glass patterns.
