There are two search modes available: simple and advanced. Simple search can include one or more words from the title, summary, keywords or full text, but does not allow the use of search operators. Advanced search allows to limit the number of search results by entering the search terms of different categories in the search window, as well as the use of Boolean search operators (AND, OR and AND NOT). In search results short formats of records are displayed and some data are displayed as links, which open a detailed description of the material (title link) or perform a new search (author or keyword link).

Selective glucose oxidation to glucaric acid using bimetallic catalysts : lattice expansion or electronic structure effect?
Žan Lavrič, Janvit Teržan, Ana Kroflič, Janez Zavašnik, Joanna E. Olszówka, Štefan Vajda, Matej Huš, Miha Grilc, Blaž Likozar, 2024, original scientific article

Abstract: Our study presents a comprehensive approach for the selective oxidation of glucose to glucaric acid (GA) by heterogeneous catalysis. We have synthesized and characterized Au/ZrO2, AuCu/ZrO2 and AuPt/ZrO2 catalysts using X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and oxygen pulse chemisorption (OPS) techniques. Combining experimental observations with in-depth density functional theory (DFT) studies, we found that bimetallic catalysts form alloys, which exhibit different characteristics than monometallic counterparts for the given reaction. We performed batch reactions, varying temperature and oxygen pressure, and used the data to construct a predictive microkinetic model. As it turned out, AuPt/ZrO2 showed the highest selectivity, yielding 32 % of GA at 100 °C and 30 barg O2. Our results provide valuable insights for the developing of efficient catalysts and point out the bottlenecks for the oxidation of glucose to GA.
Keywords: glucaric acid, glucose oxidation, catalyst characterization, density functional theory, microkinetic modelling

Šola rakov glave in vratu : Onkološki inštitut Ljubljana, 1. december 2023
2023, not set

Abstract: V zborniku je celostno predstavljena problematika rakov glave in vratu, kot jo dojemajo strokovnjaki, ki se vsakodnevno srečujejo z bolniki s temi raki. Osvetljeni so vzroki za nastanek rakov glave in vratu, incidenca, mortaliteta in sodobni epidemiološki trendi, znaki in simptomi, ki jih povzročajo, načela sodobne diagnostike in zdravljenja s posledično morbiditeto ter možnosti podporne terapije in rehabilitacije. Poseben poudarek je namenjen obravnavi teh rakov v slovenskem prostoru in nacionalnim smernicam.
