20.500.12556/DiRROS-21880 Calorimetric and optical investigation of the nematic, splay-nematic, and ferroelectric nematic phases of RM734 liquid crystal RM734 is one of the first two liquid crystal compounds reported to exhibit the ferroelectric nematic phase. At the early stage of its characterisation, a direct nematic – to – ferroelectric nematic phase transition was reported for this compound. However, subsequent studies revealed the presence of an intermediate phase between the nematic and ferroelectric nematic ones. Here, we provide additional evidence on the calorimetric signature and the optical texture of this intermediate phase, referred to as the splay-nematic phase. Next, we briefly comment on the nature of the transitions between the nematic, splay-nematic, and ferroelectric nematic phases, and the substantially different transition temperatures reported in the literature for RM734. tekoči kristali ferroelektrika true false true Taylor & Francis Združeno kraljestvo Angleški jezik Slovenski jezik Neznano 2025-04-08 13:38:58 2025-04-08 13:38:58 2025-10-24 03:50:03 0000-00-00 00:00:00 2025 0 0 str. 1-8 [in press] 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-02-19 2025-03-06 2025-03-19 538.9 0267-8292 10.1080/02678292.2025.2481076 229822979 RAZ_Lavric_Marta_2025.pdf RAZ_Lavric_Marta_2025.pdf 1 794510DEACEA14131ACD571B240B9885 fbcc10fc6f144919dd4c35588752316470522a4ff59da0c1ec0795f0929836f2 d8928117-146e-11f0-963a-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=31559 Institut Jožef Stefan 0 0 0
