Multiphase Flow of Taylor Bubbles in Rectangular Microchannels.
Regner, Dominik
2021 - English
The aim of this work is to broaden our knowledge of the behavior of Taylor bubbles in a coflowing liquid inside flat microchannels with a high aspect ratio. The primary focus is put on the near-wall region, which is difficult to study both experimentally or numerically. The investigated quantities are the thickness of a liquid film separating the bubble from the microchannel wall, wall shear stress induced by the bubble movement, and the shape and velocity of the translating bubble. Keywords: CFD model; rectangular microchannels; bubbles Available in a digital repository NRGL

Solvent Assisted 2D Mesoporous g-C3N4 Modification for Catalytic Application.
Dolai, Susmita
2021 - English
Here we show a facile and scalable new approach for the synthesis of ordered CN materials with an excellent photoactivity, which consists\nof supramolecular interfacial preorganization of monomers at the interface of two non-miscible solvents. Molecular dynamic simulations\nsupported by experimental results reveal that appropriate mono-mers and solvents choice lead to the formation of a supramolecular assembly solely at the interface of the solvents. As a proof of concept, we show the chemical and physical properties of the g-C3N4 materials after thermal condensation in various temperature. The advantages of the new method are demonstrated here through the tuneable morphologies and surface area, the formation of new electronic junctions and high activity as a photocatalyst for hydrogen evolution and pollutants degradation of the g-C3N4 materials. Keywords: CN materials; catalyticapplication; absorbance spectra Available in a digital repository NRGL

Supercritical Impregnation of Natural Extracts in Polymer.
Komárková, Anežka
2021 - English
The vision of this work is to prepare polymeric support loaded with natural extracts and their bioactive compounds in order to create\nwound dressing with anti-inflammatory and anti-bacterial properties. The use of such a dressing may contribute to the wound’s healing\nmechanism by creating a proper physiologic environment, being a barrier for microorganisms and releasing bioactive compounds to the\nwound site. Keywords: supercritical impregnation; natural extracts; polymer Available in a digital repository NRGL

Modular Synthesis of Dendritic Amphiphiles.
Edr, Antonín
2021 - English
The synthesis of such structures starts by an attachment of alkyl chain/s R and dendritic wedge/s to the starting molecules. These dendritic wedges are ended by three allyl groups so that various polar groups can be conjugated to the periphery of the wedge by so called thiol-ene click reaction. In addition to the resulting symmetrical structures, a synthesis of their unsymmetrical analogues bearing fluorescent tag on one of its arms (Figure 1) will be presented. Keywords: modular synthesis; sythesis; drug carriers Available in a digital repository NRGL

Ambient Organic Aerosol Origin at Rural Background Site in the Czech Republic.
Lhotka, Radek
2021 - English
Atmospheric aerosol (AA) are ubiquitous particles in the atmosphere that influence Earth’s climatic system, environmental interactions,\nand human health. AA is emitted directly from primary sources or formed in the atmosphere via the oxidation of gas-phase precursors\nwith subsequent partitioning resulting in low-volatility products into the particle phase. Among AA, great interest is dedicated to organic\naerosol (OA) since it can represent from 20 to 90% of the total submicron mass. Keywords: atmospheric aerosol; rural background site; measurement campaigns Available in a digital repository NRGL
