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

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

Kinetics of Keratin Acidic Hydrolysis in Batch Autoclave.
Hanika, Jiří; Kaštánek, P.; Rousková, Milena; Šabata, Stanislav; Šolcová, Olga
2017 - English
The contribution brings novel data on the non-traditional process presented during previous ICCT 2015 conference1. According to the patent application2 the hydrolysis of waste chicken feathers was performed in a reaction mixture containing water and a soluble acid catalyst with the pKa value lower than 4, in a stirred batch reactor for 0.5 to 10 hours, in the temperature range from 90 to 130°C and at the pertinent vapour pressure of reaction mixture. Kinetics of preparing a mixture of proteins and amino acids by hydrolysis of a waste material containing chicken feathers was investigated in this study.\n Keywords: batch autoclave; reaction micture; experiments Available in a digital repository NRGL

Highly time resolved measurement of atmospheric elemental and organic carbon at a typical background site in Central Europe.
Mbengue, Saliou; Fusek, M.; Schwarz, Jaroslav; Holoubek, Ivan
2017 - English
Atmospheric organic (OC) and elemental (EC) carbon play an important role in atmospheric chemistry, climate change and public health. There have been relatively few studies dealing with EC and OC in rural background sites which are less influenced by urban and industrial emissions. Nevertheless, measurements at background areas are important for understanding the transport and transformation characteristics of anthropogenic air pollutants, and their effects on various aspects of regional and global environment changes. In this study, we focus on variability of EC and OC concentrations (considering various day categories and seasons) from a rural background site which is representative for Central European rural areas.\n Keywords: organic carbon and elemental carbon; rural background; OC/EC ratio; variability Fulltext is available at external website.
