16. Novel ▫$TiO_2$▫-supported gold nanoflowers for efficient photocatalytic ▫$NO_x$▫ abatementŠpela Slapničar, Gregor Žerjav, Janez Zavašnik, Matevž Roškarič, Matjaž Finšgar, Albin Pintar, 2024, izvirni znanstveni članek Povzetek: t: In this study, we pioneered the synthesis of nanoflower-shaped TiO2 -supported Au photocatalysts and investigated their properties. Au nanoflowers (Au NFs) were prepared by a Na-citrate and hydroquinone-based preparation method, followed by wet impregnation of the derived Au NFs on the surface of TiO2 nanorods (TNR). A uniform and homogeneous distribution of Au NFs was observed in the TNR + NF(0.7) sample (lower Na-citrate concentration), while their distribution was heterogeneous in the TNR + NF(1.4) sample (higher Na-citrate concentration). The UV-Vis DR spectra revealed the size- and shape-dependent optical properties of the Au NFs, with the LSPR effect observed in the visible region. The solid-state EPR spectra showed the presence of Ti3+, oxygen vacancies and electron interactions with organic compounds on the catalyst surface. In the case of the TNR + NF(0.7) sample, high photocatalytic activity was observed in the H2 -assisted reduction of NO2 to N2 at room temperature under visible-light illumination. In contrast, the TNR + NF(1.4) catalyst as well as the heat-treated samples showed no ability to reduce NO2 under visible light, indicating the presence of deformed Au NFs limiting the LSPR effect. These results emphasized the importance of the choice of synthesis method, as this could strongly influence the photocatalytic activity of the Au NFs

20. Structural basis for the multitasking nature of the potato virus Y coat proteinAndreja Kežar, Luka Kavčič, Martin Pólak, Jiři Nováček, Ion Gutiérrez-Aguirre, Magda Tušek-Žnidarič, Anna Coll Rius, Katja Stare, Kristina Gruden, Maja Ravnikar, David Pahovnik, Ema Žagar, Franci Merzel, Gregor Anderluh, Marjetka Podobnik, 2019, izvirni znanstveni članek Povzetek: Potato virus Y (PVY) is among the most economically important plant pathogens. Using cryoelectron microscopy, we determined the near-atomic structure of PVY’s flexuous virions, revealing a previously unknown lumenal interplay between extended carboxyl-terminal regions of the coat protein units and viral RNA. RNA–coat protein interactions are crucial for the helical configuration and stability of the virion, as revealed by the unique near-atomic structure of RNA-free virus-like particles. The structures offer the first evidence for plasticity of the coat protein’s amino- and carboxyl-terminal regions. Together with mutational analysis and in planta experiments, we show their crucial role in PVY infectivity and explain the ability of the coat protein to perform multiple biological tasks. Moreover, the high modularity of PVY virus-like particles suggests their potential as a new molecular scaffold for nanobiotechnological applications.
