Hydrodynamic Behavior of Large Bubbles in Slot Channels.
Ezeji, Kingsley
We present the results of experimental investigation on the dynamics of air bubbles rising in stagnant liquid inside an inclined channel. The experiments were conducted in a Plexiglas channel having a rectangular cross-section (240×20 mm). Different channel geometries were then obtained by insertion of suitable plates into this basic channel.

Effect of Conditions on TiO2 Aerogel Crystallization Using Modified Supercritical Carbon Dioxide.
Cerhová, Marie
This work is focused on a deeper study of TiO2 aerogel SFC with scCO2 modified by mixture of ethanol and water in a ratio 1:1. The effect of temperature (40–100 °C), pressure (10–30 MPa) and modifier concentration in scCO2 (5–15 wt.%) on microstructure, purity and textural properties of TiO2 aerogel was investigated. Processed monoliths were characterized by XRD analysis, Raman spectroscopy and N2 physisorption.

Phosphorus Derivatives of Helicenes.
Beránek, Tomáš
In this work, synthetic pathways providing suitable phosphorous derivatives of helicenes and their transition metal complexes in both the racemic and the chiral forms were investigated in asymmetric Suzuki reaction.

Transition Metals Complexes with Helical 2,2´-Bipyridine Ligands.
Kos, Martin
Herein we report synthesis of series of novel chiral complexes of various metals (Cu, Re, etc.) with helical ligands containing bipyridine moiety (Fig. 1). Photochemical and photophysical properties of prepared complexes will be studied in both racemic and optical pure form.
