Cílem této bakalářské práce je návrh a implementace knihovny publikací jako zásuvného modulu pro wiki systém DokuWiki. Práce obsahuje základní informace o DokuWiki a tvorbě jejich doplňků. Dále je zde rozepsána funkcionalita, kterou bude výsledný modul obsahovat spolu s návrhem datového modelu. V poslední části je poté popsáno, jakým způsobem byly jednotlivé funkce implementovány, a jaké externí knihovny k tomu byly využity.The goal of this bachelor's thesis is to design and implement a resource library as a plugin for DokuWiki wiki system. This text contains basic information about DokuWiki and the plugin development. Then, the description of the final application follows along with the design of the data model. The last section covers the implementation of the application and contains informations about used external libraries.

Bidisperse magnetorheological fluids utilizing composite polypyrrole nanotubes/magnetite nanoparticles and carbonyl iron microspheres

Conductive polypyrrole nanotubes were synthesized with a two-step one-pot synthesis. During synthesis, the nanotubes were decorated with magnetite nanoparticles at different concentrations granting them magnetic properties. The characterization of the tubes revealed differences from the theoretical reactions. A bidisperse magnetorheological fluid (MRF) was prepared by mixing the composite polypyrrole nanotubes/magnetite nanoparticles with commercial carbonyl iron spherical microparticles in silicone oil. The rheological properties of the bidisperse system were studied under the presence of magnetic field at room and elevated temperature. An enhancement of the MR effect with the presence of the nanotubes was observed when compared with a standard MRF consisted only of magnetic microparticles. Due to the faster magnetic saturation of the nanotubes, this enhancement is exceptionally high at low magnetic fields. The stability of the system is studied under dynamic conditions where it is revealed that the nanotubes keep the standard particles well dispersed with the sedimentation improving by more than 50%.Internal Grant Agency of Tomas Bata University in Zlín, (IGA/CPS/2022/004, RP/CPS/2022/003); National Technical Library in Prague; Tomas Bata University in Zlin, TBU; Ministerstvo Školství, Mládeže a Tělovýchovy, MŠMT, MŠMT; en:MEYS, (RP/CPS/2022/007); Univerzita Tomáše Bati ve ZlíněNational Technical Library in Prague; Internal Grant Agency of Tomas Bata University in Zlin [IGA/CPS/2022/004]; project DKRVO [RP/CPS/2022/007, RP/CPS/2022/003]; Ministry of Education, Youth and Sports of the Czech Republi
