Supramolecular assemblies and gels from helicene-polypeptide conjugates: synthesis and chiroptical properties

Setnička Vladimír, prof. Ing. Ph.D. ( set...@vscht.cz)
Crassous Jeanne, dr ( jea...@univ-rennes1.fr)
This work will be focused on the preparation and characterization of new supramolecular systems based on helicene-polypeptide conjugates. The polypeptide moiety will be systematically modified to produce highly ordered supramolecular aggregates stabilized by hydrogen and other interactions. Common methods of structural analysis including highly sensitive methods of chiroptical spectroscopy (electronic circular dichroism ECD, vibrational circular dichroism VCD and Raman optical activity ROA) will be used for the characterization.

Interpretation of Raman optical activity of nucleic acids

Bouř Petr, prof. RNDr. CSc. ( b...@uochb.cas.cz)
Hopmann Kathrin Helen, Assoc. Prof. Ph.D. ( kat...@uit.no)
Spectroscopy of vibrational Raman optical activity is a new and dynamically evolving analytical method providing important information, such as about biopolymer and enzyme structure. The applications are very dependent on spectral interpretations based on the molecular dynamics and quantum chemical computational methods. For nucleic acids, although experimentally very interesting systems can be approached, including viruses, the relation between the spectrum and the structure is not completely known. A big problem are computer demands required by these complex and big molecules. We will therefore focus on development of experimental and computational methodology for model system, suitable to describe specific nucleic acid properties, such as flexibility and polarity. Modern computational methods will be both used and developed, such as combination of classical and quantum mechanics or testing models of solvent and environment during molecular interactions.

New effective separation membranes for water and wastewater treatment based on hybrid carbon-based materials

Friess Karel, doc. Ing. Ph.D. ( fri...@vscht.cz)
Current membrane separation processes allow efficient purification and physical disinfection of water from undesirable components on the basis of a size-sieving mechanism without the need for chemical agents. The pore sizes and their distribution on the membrane surface is an important factor for the effective removal of contaminants and microorganisms. The thesis will study the possibilities of using newly prepared membrane materials based on carbon materials (carbon nanotubes, graphene derivatives, etc.) with targeted surface modifications (eg doping with antimicrobial agents, etc.) in order to effectively remove collected contaminants from water. In addition to the preparation, characterization and testing of materials, the work will also include modelling of the separation process. The result of this work will be, besides the preparation of an effective separation material and describing the model, an extension of knowledge in the given membrane field.
