Retarded Forms of Lisuride
(Ing. Jan Čejka, Ph.D.)
The pharmacokinetical properties of API may be affected by the particular structure in some extent. Not only polymorphism and solvatomorphism, but also salts and co-crystals are involved. When salts of large organic acids are used, significant decrease of solubility kinetics is expected. Considering therapeutical use of an ergot alkaloid lisuride, the lower solubility would broaden the administration interval, improve the QoL of the patient and a considerably lower loading of patient’s organism is expected.

Supramolecular catalysis based on calixarene derivatives
(prof. Ing. Pavel Lhoták, CSc.)
Calixarenes are macrocyclic compounds easily accessible by base-catalyzed condensation of p-substituted phenols with formaldehyde. As the basic skeleton of these macrocycles can be regioselectively and/or stereoselectively derivatized, calixarenes are frequently used for the construction of more elaborate supramolecular systems. The aim of this work is the derivatization of calixarenes by suitable functional groups enabling the application as macrocyclic ligands in common organic catalytic reactions (e.g. various coupling reactions). Another goal is the modification of basic skeleton leading to the enhanced host-guest interactions with substrate, and consequently, to regio- and/or stereoselective reactions.

Novel calamitic liquid crystals with laterally substituted core
(doc. Ing. František Hampl, CSc.)
Recently, a formation of chiral domains in SmC phases made of some achiral rod-like mesogenes as well as amplification of the twisting power in chiral mesophases by introducing achiral rod-like molecules have been reported. The substance of this interesting phenomenon is assumed to lie in conformational chirality resulting from partially restricted rotation around single bonds in the longitudinal axis of the non-chiral mesogene core. The proposed study is aimed at investigation of the above-mentioned phenomenon. For this purpose, novel rod-like liquid crystals with laterally substituted core will be synthesized, e. g. o,o´-susbtituted biphenyl derivatives or aryl esters of arenecarboxylic acids substituted in ortho positions to ester function. Lateral substitution is expected to increase rotational barriers in the core thus facilitating the origin of the conformational chirality. Detailed study of the mesomorphous behaviour of the prepared mesogenes including correlations of the calculated rotational barriers with the found properties of the mesogenes is expected to give a better insight to the substance of the afore mentioned supramolecular chirality.

Only little attention was devoted to the initiation systems comprising Mg or Al initiators. Research will be focused on the activitity of initiators mentioned and evaluated by polymerization kinetics above and below the melting temperature of polymers and by polymer properties. The result can enrich both basic research and oriented one.

Preparation and properties of photocatalysts based on WO3 and TiO2 with the aim to improve effectiveness of photocatalytical surface water purification
(prof. Dr. Ing. Josef Krýsa)
The efficiency of photocatalysis on TiO2 is low due to the small share of absorbed sunlight and high hole-electron recombination. Different ways lead to the enhancement of photocatalytic processes efficiency. One possibility is the application of other semiconducting photocatalyst (WO3) with lower width of forbidden gap. Such a catalysts is capable to utilize radiation with higher wave lengths, and thus to utilize larger part of sun light. Unfortunately the layer of WO3 is not perfectly stable so a combination of both photocatalysts in multilayer films form seems to be a good solution.

Aging of porous ceramics
(Ing. Alexandra Kloužková, CSc., doc. Ing. Vladimír Hanykýř, DrSc. (doc. Dr. Dipl.-Min. Willi Pabst))
Aging of porous ceramics is defined as a process of irreversible composition and volume changes undergo common conditions for selected time intervals. Ceramics fired at relatively low temperatures containing fine non-crystalline reactive products are most often subjected to this process. These products may remain in the ceramic body as phases showing low stability under the water influence. Their rehydratation is usually accompanied by irreversible expansion of the ceramic body - by irreversible moisture expansion of the material. The aim of this work is the determination of the values of irreversible moisture expansion of different ceramic types, to describe effect of this irreversible expansion on the properties of porous pramic body, to describe mechanism of this rehydratation.

Effect of inorganoc and organometal compounds on properties of wood
(Ing. Irena Kučerová, Ph.D.)
Preservatives which protect wood against biological attack and fire are used repeatedly nowadays. However it is lack of information about their potential negative influence of on the wood. At the same time some chemicals that are present in preservatives induce chemical reactions, which cause damage to wood polymers. Among such chemicals are ammonium sulphate and ammonium phosphates that serve as components of fire retardants. Many roof beams in historical buildings in the Czech Republic have been repeatedly treated with these fire retardants. This treatment brought about damage to the historical wood surface consisting in a release of loose wood fibres, named as “defibring”. It can bring about serious degradation of the mechanical properties of the timber. This is borne out by the breakdown of some timber roofs in the Sydney area, Australia, which were corroded by sea salt. This project is aimed at the investigation of : A study of influence by preservatives containing inorganic and organometallic compounds on historic wood.

Similarly, different ability to network formation is observed when polymer blends based on rubber/plastic combination are crosslinked. The study of crosslinking course and network structure resulting from co-crosslinking reaction, and evaluation of crosslinking effect on product properties are basic aims of the work.
Rheological evaluation of rubbers and their mixtures
(doc. Ing .Antonín Kuta, CSc.)
Knowledge of rheological behaviour of rubbers and their mixtures is important for optimal setup of individual technological steps (mixing, extrusion, calendering,..) in rubber manufacturing. However, rheological evaluation still is not common practice in rubber industry. The behaviour during processing is more or less successfully estimated on the basis of simple conventional tests. Undoubtedly, rheological properties are related to rubber molecular structure and mixture composition. The study of these relations including relation to conventional tests will be studied.

Covulcanisation of diene rubbers
(prof. Ing. Vratislav Ducháček, DrSc.)
Combination of diene rubber compounds has a great practical importance. In compounds filled with carbon black, demanded properties can be obtained easily. In compounds filled with active silicium oxide (silica) no. This result can be rendered by insufficient homogenity of the rubber vulcanisate. For this reason, the influence of rubber composition on the course of vulcanisation (covulcanisation), morphology of rubber vulcanisate , extent of its crosslinking, and its mechanical properties, namely tensile ones including tear strength, abrasion and aerobic ageing resistance is necessary to be investigated. New findings obtained will contribute to the understanding of vulcanisation mechanism and appreciation of application possibilities of vulcanised rubber based on combination of diene rubbers

Modification of rubber compounds with liquid elastomers
(Ing. Zdeněk Hrdlička, Ph.D., doc. Ing. Antonín Kuta, CSc.)
Low-molecular weight liquid elastomers can facilitate processing of rubber compounds from standard high-molecular weight rubber. They can also reduce the energy comsumed at mixing. However, these liquid modifiers may co-vulcanise with the solid rubber insufficiently. The main challenge of the disertation is to investigate the influence of liquid rubber microstructure on ability of co-vulcanisation of the both rubbers and on the nature of vulcanisate network.
