Changes in Sub-micron Number Size Distributions at Czech Rural and Urban Background Stations in the Last Ten Years.
Zíková, Naděžda; Ondráček, Jakub; Wagner, Zdeněk; Ždímal, Vladimír
2017 - English
In this work, not only total concentrations are evaluated, but also particle number size distributions (PNSD) are compared in the last decade at the two stations, and possible explanations for the change in concentrations and PNSD changes are looked for. Additionally, also the change in the frequency and strength of the NPF events is evaluated.\n Keywords: SMPS; long-term measurement; rural background Available in a digital repository NRGL

Use of Water-Modified Supercritical Carbon Dioxide for Direct Preparation of CrystallineMonolithic TiO2 Aerogels.
Cerhová, Marie
2017 - English
We studied a combination of supercritical CO2 and water for the preparation of crystalline and pure nanostructured TiO2 without any thermal processing. The effect of temperature (40–100 °C) and pressure (10–30 MPa) on the purity, structural and textural properties was investigated.\n\n\n Keywords: carbon dioxide; TiO2; pressure Available in a digital repository NRGL

Helicene-based Thioureas.
Jakubec, Martin
2017 - English
The main goal of this work was to introduce the helicene moiety into the structure of bis(aryl)thiourea, to prepare a new type of a helicene-based organocatalyst. Several aryl(helicenyl)thioureas were synthesized so far. Their ability to form hydrogen-bond complexes with various types of substrates was verified using NMR and the activity of the catalysts is currently being explored.\n Keywords: helicene moiety; ability; nmr Available in a digital repository NRGL
