Development of Continuous Technology for the Preparation of Pharmaceuticals
Jaklová, Natalie
2024 - anglický The present research focuses on the transition of a batch reaction assisted by phase transfer catalyst (PTC) into continuous process. The first reaction studied was an N-alkylation reaction with methyl ester of the 1-methyl-10α-methoxydihydrolysergic acid (MeLUME) as product. MeLUME is one of the intermediates in synthesis of drug Nicergoline. The N-alkylation occurs in two different immiscible phases and the bridge between these phases is the phase transfer catalyst. The study was performed in several different continuous flow apparatuses. The best results were obtained in a capillary reactor, with assistance of ultrasound.

Thin Film Photocatalysts on the Basis of g-C3N4
Schimon, Domonik
2024 - anglický This study revolves around the synthesis of powder g-C3N4, fabricationof thin g-C3N4 films and their efficacy in degrading pollutants, assessed through experimentation in a batch photoreactor (BPR) and a slit geometry photomicroreactor (PMR)2. The photocatalytic activity of g-C3N4 was tested with 4 different model substances: fluorescent dye, rhodamine B, was used as a reference substance and three separate antibiotics, which are emerging wastewater pollutants, namely tetracycline, trimethoprim, sulfamethoxazole.

Measurements of New Particle Formation in the Atmosphere
Špalová, Anna
2024 - anglický In this work, the formation of particles and their transformation to larger sizes will be studied by measuring the concentration of molecular clusters. The measurement will take place at a rural background site National Atmospheric Observatory Košetice. At the ground level, a Neutral and Air Ion Spectrometer (NAIS) able to measure both neutral and charged clusters or particles ranging from 0.8 to 40 nm in diameter will be used together with a Particle Size Magnifier (PSM) able to measure neutral clusters as small as 1 nm in diameter up to 12 nm. Larger particles will be measured by a Scanning Mobility Particle Sizer (SMPS). At a height of 230 m above ground level, there will be another SMPS and also a nanoSMPS able to detect particles as small as 1 nm in diameter.

Utilization of electrochemically induced cleavage of various sulfonimides
Salvadori, Karolína
2023 - anglický In this work, we describe the unexpected electrochemical cleavage of sulfonimides, providing a direct pathway to corresponding sulfonamides. For this purpose, 16 substances were synthesized and tested, reflecting the influence of different electron effects of -SO2Ph-R substituents, and the impact of the number of nosyl units present in molecules. In the case of octakis-nosylated calixarenes, the electrochemical cleavage via direct potential-controlled electrolysis was compared with conventional organic synthetic procedures. After electrolysis, all prepared sulfonamides were isolated in excellent yields.

Cultivation of Limnospira maxima and utilization of its fresh biomass in human nutrition
Vásquez, Claudia
2023 - anglický This work aims to enhance productivity, efficiency and sustainability of L. maxima cultivation as well as to determine the safe microbiological conditions for the nutritional use of fresh spirulina biomass. Various parameters such as light intensity, light spectral composition, temperature, pH, CO2, and culture media composition can be optimized. A series of experiments were performed to find the most suitable configuration to cultivate L. maxima, defined by cyanobacterium productivity and yield as well as other metabolites production such as phycocyanin (C-PC) and carotenoids.

Organic fluorine content and change during thermal treatmen

2023 - anglický We have previously described how pyrolysis affected the content of selected PFAS representatives.4,5 However, we could not determine with certainty whether they were merely cleaved or mineralised. Therefore, we focused on the change in organic fluorine content (part of PFAS) and analysed its thermal behaviour in inert (sea sand) and heterogeneous (sewage sludge) material.
