Generování těkavých specií přechodných kovů pro analytickou atomovou spektrometrii se zaměřením na účinnost generování, prekoncentraci, identitu těkavých specií a studium mechanismu generování
Musil, Stanislav
2018 - Czech
Předkládaný soubor 8 publikovaných prací a jednoho patentu se věnuje právě této problematice. Zaměřili jsme se na studium mechanismu generování a identifikaci těkavých specií v plynné fázi při generovaní Ag1, Au3 a Cu9 s detekcí AAS. Pomocí přístrojů pro charakterizaci velikosti částic aerosolu a transmisní elektronové mikroskopie jsme identifikovali nanočástice těchto kovů v plynné fázi. Keywords: volatile species; atomic absorption spectrometry; generation of volatile species Available on request at various institutes of the ASCR

Understanding the Principles of Diastereomeric Complexes of Chiral Urea Derivatives.
Cuřínová, Petra; Jakubec, Martin; Storch, Jan; Holakovský, R.
2017 - English
The main target of this work based on the NMR studies is to elucidate the structural principles which are responsible for the action of the chiral selectors at hand, and thus to be able to predict the new promising structures useful as NMR shift reagents. Keywords: NMR solvating agent; chiral recognition; diastereomeri complex Available in a digital repository NRGL

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

Do Invasive Alien Species Affect Diversity of Local Communities?
Kindlmann, Pavel; Honěk, A.; Martinková, Z.
2017 - English
Here we present results of simulation models to investigate the diversity dynamics in a theoretical system consisting of an "original" community of native species and an invasive alien species that invades this community, thus creating a "new" community. See Kindlmann et al. (2017) for full details of the simulations and results. Keywords: invasive species; local diversity Available at various institutes of the ASCR

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
