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

Aerosol Particle Formation During Summer Campaign at Rural Background Site Košetice.
Holubová Šmejkalová, Adéla
2017 - English
Based on the SMPS data, the individual days were classified as NPF event, non-event and undefined, according to the method of Dal Maso et al. (2005). In order to obtain daily patterns, PSM data were averaged for all NPF event, and all non-event days. Relations between NPF, daily variability of meteorological elements, and aerosol particles precursor concentrations were evaluated. Keywords: atmospheric aerosols; new particle formation; measurement campaign Available in a digital repository NRGL
