3. An Overview of the Characteristics of Free Market EconomiesAndi Jamšek, 2021, magistrsko delo Opis: In this work we are collecting and processing basic information that allows us a general overview of the five most popular global, free market economies which are: the exchange of currency (foreign exchange), rare metals, stocks, residential real
estate and the cryptocurrency markets. By having more in-depth knowledge about the possibilities that each separate financial instrument or asset offers we are devising a strategy suited for different types of investors. Any economical system in its most
natural state will create some sort of dynamic; it is possible to draw parallels between the free-economy and the Lotka-Volterra predator behaviour equations, which can help us to better visualise the behaviour of such systems. We try to compare the model with real life scenarios that had greatly affected some of the economies, one of them being the popularization of cryptocurrencies in 2017 and the other being the most recent
Coronavirus epidemic. By having a rough comparison we can see a clearer picture of the practical uses and the necessities of having an increased and better selection of such models.

4. Removal of copper from aqueous solutions with zeolites and possible treatment of exhaust materialsIztok Arčon, Janez Kovač, Margarita Popova, Nataša Zabukovec Logar, 2021, izvirni znanstveni članek Opis: The mechanism of Cu2+ loading into commercially available natural HEU-type and synthetic LTA-type zeolites for their
possible use in environmental processes, such as water and air treatment applications, was studied. Elemental analysis,
SEM/EDXS, XRD, XAS and XPS analyses revealed 4-fold coordination of Cu2+ cations with oxygen atoms in the pores, a
predominant location of copper atoms on the surface of crystallites and retained crystallinity of zeolites throughout the
processes. The post-treatment of Cu2+-loaded samples with HCl and/or NaCl solutions confirmed the predominantly
reversible sorption of copper on zeolites from aqueous solutions by ion-exchange mechanism and, therefore, excellent
regeneration possibilities for both types of zeolites. Furthermore, with the calcination of exhaust metal-loaded zeolites,
catalysts for total toluene oxidation reaction, as a model VOC pollutant, were obtained.
