Study of the influence of nanoparticles on water properties
Šram, Matěj ; Komendová, Renata (referee) ; Řezáčová, Veronika (advisor)
This work deals with the study of the influence of platinum nanoparticles with a size of 3 nm on the properties of water in a porous system. SiO2 with a defined pore size was used as a porous system, which can simulate the mineral component of the soil. The theoretical part deals with the properties of free and porous water and the impact of nanoparticles on the environment. In the experimental part, the properties of free water, water in the porous system and the influence of the presence of platinum nanoparticles on these systems are investigated using differential scanning calorimetry (DSC). The observed processes were melting, solidification and evaporation, and derived quantities such as crystallization and melting point.

The ifluence of inorganic nanoparticles on environmental compartments
Šram, Matěj ; Řezáčová, Veronika (referee) ; Komendová, Renata (advisor)
Nanoparticles are one of the newer risks for the environment. Their consumption is constantly rising and thus their entry into the environment is inevitably increasing. At the same time, nanopollutants are formed as by-products of anthropogenic activity. The theoretical part of the bachelor thesis describes the characteristics of nanoparticles and points out the possible risks in relation to the environment. In the experimental part, this work deals with the effect of platinum nanoparticles on dissolved organic matter. Platinum metals in the form of nanoparticles are significant anthropogenic pollutants, because they are released from automotive catalysts and are therefore the subject of this study.
