Preparation of Partially Fluorinated Polyaromatics by Photocyclization of Stilbenes.
Jakubík, Pavel; Storch, Jan; Žádný, Jaroslav; Pfleger, Jiří; Církva, Vladimír
2017 - English
Synthetic strategies to partially fluorinated polyaromatics by photocyclization were examined, leading to both 1,2,3,4-tetrafluoro[6]helicene (1) and 1,2,3,4,13,14,15,16-octafluoro[6]helicene (2), and to 1,2,3,4-tetrafluoro[5]phenacene (3) and 1,2,3,4-tetrafluoro[6]phenacene (4). Thin films of the prepared compounds were characterized for their electrical properties and incorporated into OFET structures.

High-Volume Municipal Solid Waste Incineration Bottom Ash Concrete.
Reiterman, P.; Holčapek, O.; Krausová, A.; Šyc, Michal; Keppert, M.
2017 - English
About 50% of Municipal Solid Waste is incinerated (MSWI) in Europe what represent ca. 50 Mt/a of MSWI bottom ash (BA). Bottom ash contains several marketable components (iron scrap, non-ferrous metals, glass) which can by separated from the main BA stream and placed on the market with secondary sources. The resting material is, by its composition and properties, similar to natural aggregates and can be used in this way. The influence of metals separation form BA on its behaviour in concrete was tested by using BA from Praha Malešice Waste-to-Energy Plant. Particle size fractions 4/8 and 8/16 mm of this BA can be used as aggregates in concrete up to 50 vol. % of given fraction without any significant loss of concrete strength. The combination of valuable component separation form BA and recycling of the rest portion as aggregates feature promising way of BA management reducing the amount of BA to be landfilled to minimum.

39M-IMMEDIATE Research Report: Remarks on Repeatability Experiments and Perspective Exploitation of MAE Pt/C\nElectrocatalysts.
Kaluža, Luděk; Gulková, Daniela; Soukup, Karel
2016 - English
The 36-39 months of the projekt solution were devoted to summarize aspects of the most perspective results on Pt/C electrocatalysts preparation to focus on industrial expoitation. Chellenges of Pt dispersion in the Pt/C were compared with preliminary outcomes from volumetric determination of hydrogen adsorption.

Partition Coefficients Octanol-water of Selected (–)-Menthol-Substituted Chiral Ionic Liquids.
Andresová, Adéla; Feder-Kubis, J.; Florianová, M.; Basarabová, B.; Čubová, K.; Bendová, Magdalena
2016 - English
Octanol-water partition coefficients, log P, may be considered as one of the indicators for the tendency to bioaccumulation. For this reason, log P was measured as a function of the alkyl chain length on the cation for selected species of the 1–[(1R, 2S, 5R)-(–)-menthoxymethyl]-3-alkylimidazolium chloride ionic liquid series. The data were processed by means of mathematical gnostics to evaluate the relationship between the structure of the studied ionic liquids and log P.

Planet Earth – Global Batch Bioreactor.
Hanika, Jiří; Šolcová, Olga; Kaštánek, František
2016 - English
Planet Earth, precisely speaking its surface shell, might be considered as a huge, multiphase, batch, biochemical reactor heated by Sun, whose energy is a unique resource. The Sun ensures our earthly life uncondicionally; moreover, it compensated the heat losses of the land, water and ice by radiation emitted from the Earth surface to its surrounding space at night. It is evident that in this macro-reactor the complex transport phenomena occurs in phases;involving mass, heat and momentum. Obviously such a responsive batch system can be only limited by resouces of carbon materials utilized in energy produstion for industrial and chemical processes.
