Robust Approach for Environmental and Health Practice: Novel Paradigm for Data Treatment and Analysis
 Wagner, Zdeněk ; Ocelka, T. ; Pavliska, L.
Knowledge of concentration of atmospheric aerosol particles may provide an important information in applications concerning human health. Aerosol studies reach into several fields of science. In the past decades it was shown that enhanced concentration of atmospheric aerosol lead to increased mortality on cardiopulmonary diseases and lung cancer. This work presents a robust method of estimation of particle size distribution based on mathematical gnostics. The algorithm may either be used as a manual tool for analyzing a small number of particle size distributions ex post or as a routine implemented in automatic monitoring devices for near real time processing of measured data and immediate online display on a web site. The method has sucessfully been implemented for near real time analysis of data measured by a scanning mobility particle sizer conformant to recommendations defined in the framework of the EUSAAR project.

Mutual Solubilities of Ammonium-Based Ionic Liquids with Water and with Water/Methanol Mixture
 Machanová, Karolina ; Jacquemin, J. ; Wagner, Zdeněk ; Bendová, Magdalena
This work presents a study on solubility in water and in water/methanol mixture of a set of ILs composed of the bi (trifluoromethylsulfonyl)imide anion and of the N-alkyl-triethyl-ammonium cation (abbrev. [NR222][NTf2]) with the alkyl chain R ranging from 6 to 14 carbons. These ILs were successfully tested for enantioselective hydrogenation of β-ketoesters catalyzed by the chiral complex Ru-BINAP in presence of methanol [1]. From which, it appears that these ILs immobilise the catalyst in the mixture for easier recycling and further re-use and protect it from air/oxygen. The final separation of the product is carried out by rinsing the solution with water, which may also wash out the ILs with catalyst. For this reason, mutual solubilities between ILs and water, as well as between ILs and methanol/water mixture need to be investigated in detail.
