3. Influence of the new archival Law on the acquisition policy of archives in CroatiaDarko Rubčić, Željka Dmitrus, 2018, strokovni članek Povzetek: Archivists tied between the development of information technology, information science and new legal regulations must deliberate the future acquisition policy of the archives in different circumstances. For decades we have been talking about an explosion of unconventional material. The development and quantity of new information were faster than us. In this paper, we wanted to point to some of the new circumstances of the archival service in Croatia, or the more or less the entire archival community. Archivists in Croatia were particularly interested in the adoption of the Law on amendments to the Law on archival material and archives in May 2017 and the recent adoption of a new, comprehensive Law on archival material and archives. In the context of these changes, which will happen in the future or have already occurred, we must ensure the protection and preservation of the authenticity of the already generated electronic material and conversion into a digital format suitable for long-term preservation and after being taken over to the archives. In addition, we must educate people new competencies. Encouraged by these changes, we will try to describe the prospect of future acquisitions policy of archives.

4. Hydration of belite–ye’elimite–ferrite cement with addition of red mud and waste concreteMaruša Mrak, Nina Daneu, Sabina Dolenec, 2025, izvirni znanstveni članek Povzetek: The hydration kinetics, phase assemblage, microstructure and mechanical properties of belite–ye’elimite–ferrite (BYF) cement containing different secondary raw materials (red mud and waste concrete) and cured at 5, 20 or 608C were examined. Different secondary raw materials were found to lead to changes in cement hydration. The influence of these materials on the hydration processes of belite and ferrite became more noticeable at a curing temperature of 58C, but diminished with an increase in curing temperature. The BYF cement made with red mud exhibited accelerated hydration, particularly at 58C, due to higher contents of mayenite and alkali sulfate compared with cement with natural materials and waste concrete. Red mud inhibited early ettringite formation due to the presence of aphthitalite but promoted monosulfate through accelerated ye’elimite hydration. Ferrite hydration was delayed by red mud, as alkali sulfates promote belite reactivity and calcium silicate hydrate (C-S-H) formation over stra¨tlingite. Periclase increased siliceous hydrogarnet formation at higher temperatures, supporting delayed yet stable strength development. The curing temperature impacted the morphology of the C-S-H (transitioning from a fine fibrillar-like structure to a foil-like structure) and affected the chemical composition of hydrates, resulting in a lower incorporation of iron in hydrogarnet and C-S-H at higher temperatures. Increased curing temperatures promoted aluminium uptake in calcium aluminium silicate hydrate.

6. EITRM118891 D4.4.1 : Report on technical & economic analysis of the demonstration resultsVilma Ducman, Anže Tesovnik, Snježana Miletić, Gorazd Žibret, Lubica Kriskova, Christos Georgopoulos, 2024, elaborat, predštudija, študija Povzetek: The Geological Survey of Slovenia (GeoZS), with the assistance of the ENALOS Research and Development (ENALOS), the Slovenian National Building and Civil Engineering Institute (ZAG) and the Katholieke Universiteit Leuven (KUL), has compiled a report documenting the demonstration and application phase of the project.
This report contains a technical analysis on the materials produced as well as an economic analysis, and thus more accurately calculates the financial benefits of the technology.

8. Ferroelectric fluids for nonlinear photonics : evaluation of temperature dependence of second-order susceptibilitiesMatija Lovšin, Luka Cmok, Calum Jordan Gibb, Jordan Hobbs, Richard J. Mantle, Alenka Mertelj, Irena Drevenšek Olenik, Nerea Sebastián Ugarteche, 2026, izvirni znanstveni članek Povzetek: Ferroelectric nematic fluids are promising materials for tunable nonlinear photonics, with applications ranging from second harmonic generation to sources of entangled photons. However, the few reported values of second-order susceptibilities vary widely depending on the molecular architecture. Here, we systematically measure second-order NLO susceptibilities of five different materials that exhibit the ferroelectric nematic phase, as well as the more recently discovered layered smectic A ferroelectric phase. The materials investigated include archetypal molecular architectures as well as mixtures showing room-temperature ferroelectric phases. The measured values, which range from 0.3 to 20 pm V−1, are here reasonably predicted by combining calculations of molecular-level hyperpolarizabilities and a simple nematic potential, highlighting the opportunities of modelling-assisted design for enhanced NLO ferroelectric fluids.

9. Measuring chloride binding in cementitious materials : a review by RILEM TC 298‑EBDFabien Georget, Arezou Babaahmadi, Alisa Machner, Maruša Mrak, Sabina Dolenec, Qing Xiang Xiong, Joseph Shiju, Didier Snoeck, Prannoy Suraneni, William Wilson, 2025, pregledni znanstveni članek Povzetek: The phase assemblage evolution of binders with novel supplementary cementitious materials (SCMS) during exposure to adverse environments needs to be quantified to accelerate their adoption, and further optimize binder formulation. As such, the interaction between chloride and cementitious matrices with novel SCMs needs to be quantified. The goal of workgroup 2 of RILEM TC EBD-298 is to assess the methods used to quantify chloride binding. This state-of-the-art report reviews the standardized and novel methods to measure chloride binding through an average content (acid/water soluble) or a specific bound content per phase (XRD, TGA, SEM–EDS, …). Each method is presented with respect to our current understanding of chloride binding and speciation in cementitious materials. The discussion around the purpose, use and reporting of each method highlights the gaps limiting the comparison between studies, in particular the lack of standard protocol, and complementary characterization. This review is the groundwork for a “cookbook” of experimental workflows to investigate chloride binding in modern cementitious binders.
