161. Feljtonski potopisni prispevki Alme M. Karlin in Zofke KvederKatja Mihuko Poniž, 2018, izvirni znanstveni članek Opis: V prispevku je analiziran prvi cikel člankov Alme M. Karlin o potovanju v Južno Ameriko, ki so bili objavljeni v časopisu Cillier Zeitung od 15. februarja 1920 do 30. novembra 1921- V drugem delu članka so potopisni feljtoni Alme M. Karlin primerjani z besedili Zofke Kveder, ki pripadajo istemu žanru. Primerjava razkriva, da sta obe pisateljici dobro poznali lastnosti tega žanra, živost in komunikativnost besedil pa sta ustvarjali z vnašanjem leposlovnih pripovednih strategij v publicistično besedilo.

162. Crystal habit modification of Cu(II) isonicotinate-N-oxide complexes using gel phase crystallisationDipankar Ghosh, Katja Ferfolja, Žygimantas Drabavičius, Jonathan Steed, Krishna Kumar Damodaran, 2018, izvirni znanstveni članek Opis: We report the crystallisation of three forms of copper(II) isonicotinate-N-oxide complex and their phase interconversion via solvent-mediated crystal to crystal transformation. The different forms of copper complex have been isolated and characterised by single crystal X-ray diffraction. Gel phase crystallisation performed in hydrogels, low molecular weight gels and gels of tailored gelator showed crystal habit modification. Crystallisation in aqueous ethanol resulted in concomitant formation of blue (form-I) and green (form-II/IV) crystals while use of low molecular weight gel results in selective crystallization of the blue form-I under identical conditions. Comparison of gel phase and the solution state crystallisation in various solvent compositions reveals that the blue form-I is the thermodynamically stable form under ambient conditions.
