33. Mastering the growth of antimonene on ▫$Bi_2Se_3$▫ : strategies and insightsRoberto Flammini, Conor Hogan, Stefano Colonna, Fabio Ronci, Mauro Satta, Marco Papagno, Ziya S. Aliev, Sergey V. Eremeev, Zipporah Rini Benher, Sandra Gardonio, 2025, izvirni znanstveni članek Opis: Antimonene, the two-dimensional phase of antimony, appears in two distinct allotropes when epitaxially grown on Bi2Se3: the puckered asymmetric washboard (α) and buckled honeycomb (β) bilayer structures. As-deposited antimony films exhibit varying proportions of single α and β structures. We identify the conditions necessary for ordered, pure-phase growth of single to triple β-antimonene bilayers. Additionally, we determine their electronic structure, work function, and characteristic core-level binding energies, offering an explanation for the relatively large chemical shifts observed among the different phases. This study not only establishes a protocol for achieving a single β phase of antimonene but also provides key signatures for distinguishing between the different allotropes using standard spectroscopic and microscopic techniques.

34. Čas in minevanje v poeziji Lili Novy : magistrsko deloAnja Žnidarčič, 2025, magistrsko delo Opis: V magistrski nalogi sem predstavila poezijo Lili Novy, ki je bila izdana v dveh pesniških zbirkah Temna vrata (1941) in Oboki (1959) ter v pesniški zbirki Črepinje in druge pesmi (2005), v kateri so izbrane pesmi napisane v nemškem jeziku in prevedene v slovenski jezik. V nalogi sem se osredotočila na motive časa, minevanja in starosti. Prva dva dela temeljita na pregledu in povzemanju teoretskih in literarno teoretskih besedil. V prvem delu sem predstavila nekatere teorije, ki so skušale razložiti pojem časa. V drugem delu sem predstavila recepcijo poezije Lili Novy, ki je bila ob izidu njenih dveh pesniških zbirk skromna in še danes ni veliko raziskovalcev in raziskovalk, ki bi se z njeno poezijo ukvarjali. Kljub temu, da poeziji priznavajo kvaliteto, še vedno ni sprejeta v slovenski literarni kanon. V tretjem delu sem analizirala poezijo s fokusom na motivih časa in minevanja, ugotavljala sem, kako se lirski subjekt sooča s tem, da čas mineva in s tem prinaša spremembe, tako kolektivno kot v intimnem doživljanju posameznika.

36. A 1.8 m class pathfinder Raman LIDAR for the northern site of the Cherenkov Telescope Array Observatory : technical designOtger Ballester, O. Blanch Bigas, Joan Boix, Paolo G. Calisse, Anna Campoy-Ordaz, Sidika Merve Çolak, Darko Kolar, Samo Stanič, Marko Zavrtanik, Miha Živec, 2025, izvirni znanstveni članek Opis: This paper presents the technical design of the pathfinder Barcelona Raman LIDAR (pbrl) for the northern site of the Cherenkov Telescope Array Observatory (Northern site of the Cherenkov Telescope Array Observatory (CTAO-N)) located at the Roque de los Muchachos Observatory (Roque de los Muchachos Observatory (ORM)). The pBRL is developed for continuous atmospheric characterization, essential for correcting high-energy gamma-ray observations captured by Imaging Atmospheric Cherenkov Telescopes (IACTs). The LIDAR consists of a steerable telescope with a 1.8 m parabolic mirror and a pulsed Nd:YAG laser with frequency doubling and tripling. It emits at wavelengths of 355 nm and 532 nm to measure aerosol scattering and extinction through two elastic and Raman channels. Built upon a former Cherenkov Light Ultraviolet Experiment (Cherenkov Light Ultraviolet Experiment (CLUE)) telescope, the pBRL’s design includes a Newtonian mirror configuration, a coaxial laser beam, a near-range system, a liquid light guide and a custom-made polychromator. During a one-year test at the ORM, the stability of the LIDAR and semi-remote-controlled operations were tested. This pathfinder leads the way to designing a final version of a Cherenkov Telescope Array Observatory (CTAO) Raman LIDAR which will provide real-time atmospheric monitoring and, as such, ensure the necessary accuracy of scientific data collected by the CTAO-N telescope array.

38. Towards a sustainable energy future : evaluating Arundo donax L. in continuous anaerobic digestion for biogas productionKarlo Špelić, Mario Panjicko, Gregor Drago Zupančič, Anamarija Lončar, Ivan Brandić, Ivana Tomić, Ana Matin, Tajana Krička, Vanja Jurišić, 2024, izvirni znanstveni članek Opis: Abstract
In response to the EU's REPowerEU initiative (COM (2022) 108) which encourages an increase in biogas production by 20% in member states by 2030 to boost energy independence, it has become essential to identify sustainable alternatives to traditional feedstocks for biogas production, especially in the EU Member states where there is still high dependence on corn silage as the main raw material in biogas plants. While corn silage, predominantly used in the European biogas plants today, serves primarily for the livestock sector, alternative sources need to be explored. Therefore, this study aimed to evaluate the potential of Arundo donax, a perennial energy crop, as an alternative feedstock in a continuous anaerobic process. The biogas yield and its quality, characterized by CH4, CO2, H2S and O2 content, were determined during a continuous process with A. donax, compared with two mixed feedstocks of A. donax and corn silage over a 5‐month period in a continuous anaerobic digestion process. The results revealed that A. donax exhibits a biogas yield and methane content comparable to corn silage, indicating its potential as a viable and sustainable alternative feedstock for biogas production.

39. Narrowband-light-triggered photothermal CO2 desorption from monolithic sorbents : lecture at Institute of Materials for Electronics and Magnetism, Parma, Italy, 18. 3. 2025Blaž Belec, 2025, predavanje na tuji univerzi Opis: The widespread deployment of Carbon Capture, Utilisation and Storage (CCUS) technology faces many challenges, where high operating costs are one of the main barriers. While significant research is dedicated to more efficient CO2 sorption, a shortage exists in developing cost-effective desorption methods. The most applied CO2 desorption method is the temperature swing method (TSM), involving heating the entire reactor > 100 °C for extended periods, resulting in high energy consumption.
An alternative approach to reduce energy demand during desorption is utilising light, which, combined with photothermal (PT) nanoparticles, can be converted into heat. Contrary to TMS, the PT approach allows precise and localised gas desorption due to the material’s inherent properties. Since PT nanoparticles display narrow absorption peaks, to achieve maximum PT effect with the lowest given power, precise light sources with concentrated power are required. Still, the main challenge of the PT approach is to reach a temperature > 100 °C for complete CO2 desorption and long-lasting cyclability.
The Peak Absorption Targeted Photothermal Desorption concept is a novel approach which uses low-energy, narrowband light sources—preferably at wavelengths corresponding to the peak absorption (λmax) of thermally stable photothermal (PT)-active monolithic sorbents—to efficiently desorb CO2. By optimizing light-to-heat conversion, this approach aims to achieve complete CO2 desorption with up to 90% less energy consumption compared to traditional thermal management systems (TMS).
