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.

Magnesium Silicide and Germanide from Waste as a Source of CVD Precursors and Ultrapure Semiconductors.
Bumba, Jakub
From that reason the newly patented process, in which waste photovoltaic panels and optical lenses served as a raw materials, was tested to be the lucrative source of silicon or germanium for CVD precursors.

Single-Step Purification of Raw Biogas to Biomethane Quality by Hollow Fiber Membranes without any Pre-Treatment – Innovation in Biogas Upgrading.
Žák, Michal
Herein, a radical innovation in biogas production is presented using a single-step membrane purification technology without any necessary pre-treatment steps for contaminant removal. Asymmetric hollow fiber membranes with a thin, selective, non-porous layer made from polyester carbonate on the bore side were successfully used in a single-step raw biogas upgrading process at biogas plant Choťovice in Czech Republic.\n

Analyzing the Experimental Thermodynamic Data for Ionic Liquids and their Study as Thermal Energy Storage Materials.
Čanji, Maja
The aim of this work is to characterize a series of 1-alkyl-3-methylimidazolium saccharinate ionic liquids (alkyl standing for butyl, hexyl, octyl, and decyl), analyze the experimental data, and assess their potential application in thermal energy storage.\n

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.

From Cationic Carbosilane Dendrimers and Glycodendrimers towards Multifunctional Dendritic Wedges.
Müllerová, Monika
Here we present the CDWs of the 1𝑠𝑡–2𝑛𝑑 generation with allyl groups at the periphery and a hydroxy/amine terminated linker. The suggested synthesis requires highly selective reactions with excellent yields. Moreover, due to an employment of strong nucleophiles or basic/acidic conditions during the synthesis, it is essential to select\nconvenient protecting groups, which will be briefly discussed.\n

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.
