Design of Database for Sale and Purchase of Used Motor Vehicles
Kubík, Lukáš ; Plocek, Jiří (referee) ; Dydowicz, Petr (advisor)
The bachelor thesis deals with the design of the information system for purchase and sale of used motor vehicles. The first section contains the theoretical background to explain used procedures and methods. The second part is focused on the analysis of the current state of the information system in the company. The last section contains design, possible solutions in the implementation of application and economic evaluation.

Study of solid fraction of the atmospheric aerosol of Pilsen by X-ray powder diffraction
Vik, Ondřej ; Havlíček, David (advisor) ; Plocek, Jiří (referee)
In this diploma thesis there was studied a composition of a solid fraction of the atmospheric aerosol of the daily measurements from Pilsen by X-ray powder diffraction by the method of the parallel beam. The phase analysis was accomplished by comparing of the diffraction dates with a database of compounds usually occurring in the solid fraction of the atmospheric aerosol in this area. This database was created from works published earlier. In these samples there were also identified asbestos fibers of actinolite by the scanning electron microscope with EDS module. In this thesis there was also described a transport of several anthropogenic compounds of the atmospheric aerosol in dependence on a meteorological situation. Powered by TCPDF (www.tcpdf.org)

Ecological Applications in Modern Chemistry 2015 : Book of abstracts
Plocek, Jiří
Ecological Applications in Modern Chemistry 2015 is 2nd year of the EAMCH conference. The scope of this conference is focused on all renewable energy sources and environmental aspects of modern chemistry and technologies. Typically it includes: materials for hydrogen fuel cells, ionic conductors, piezoelectric and magnetic materials, materials for solar cells. The lectures deals with practical applications of these technologies, especially with relation with environment (water, atmosphere, etc.) are welcomed too.

Preparation of nanoforms of layered piezoelectric of systems BI2O3-TA(2)O(5)-AO (A=CA,SR,BA)
Štarman, S. ; Matz, V. ; Kváča, Z. ; Mohyla, M. ; Olšák, V. ; Plocek, Jiří ; Vaněk, Přemysl ; Tylš, B.
Based on the known Aurivillius phases types ABi2Ta2O9 and A2BiTaO6 ( A=Ca, Sr, Ba) were supplemented with new compositions of layered tantalates, which resulted the possibility of the existence of a new phase Sr2BiTaO6. Ternary compounds with piezoelectric structure were prepared as nanoforms by solgel reactions of homogeneous acetate Bi, Ta, A and subsequent annealing in a controlled atmosphere. Annealing temperature was determined from DSC curves based on the weight loss and phase transitions. Composition and structure of nanocrystals has been analyzed by X-ray diffraction (XRD), scanning nanomorphology (SEM) and acoustic measurements.
