Tomašák, Lukáš ; Jankovský, Jaroslav (referee) ; Řezníček, Michal (advisor)
The work is dedicated to the production of a thick film with resinate paste on a ceramic substrate based on a proposal test motive. It introduced the optimization of the workflow leading to the successful realization of the layer. Using an electron microscope, it is performed evaluation of the quality of resultant layer and analysis of the composition of the paste. In the last part of the work it is carried out measurements of temperature and electrical properties of resinate paste.

Sanitary Ceramics
Foret, Martin ; Kolařík, Pavel (referee) ; Zdařil, Zdeněk (advisor)
My thesis is a presentation of Jika Laufen for the international exhibition Expo 2015 in Milan. The work consists of designing and installing sinks into the exposure so that they are in a uniform manner. I designed the concept of the well for several reasons: the bathroom is an intimate space where it should be emphasized emotion , atmosphere and feelings. It is a space where a person should relax. The second aspect is that the ceramic has an organic origin, came from the ground and through the fire becomes very durable and solid. A no less important is the third aspect, exist on the context. Expo is an international exhibition and therefore the presentation of this forest exposure does not represent a Czech company, but also a Czech environment, where you will find beautiful nature and sources of known rivers. My concept is based on emotion and contrast materials. Delicate white ceramics have planted in a sharp stone and dark green leafy moss, creating a contrast full voltage . The exhibition of this type should not be missed even modern technology. That is my proposal represented feeler drain, which is around the perimeter of the sink hidden under the edge so as not to disturb the perception of the whole.

Stents and their applications in medicine
Sokl, Antonín ; Němec, Karel (referee) ; Molliková, Eva (advisor)
The aim of this bachelor thesis, which deals with types of stents and their use in medical area, is the provision od detailed reserches of the most frequently used biomaterials, namely details of metals, ceramics, polymers and composites, considering the suitability of their use for the production of substitutes for particular human body structures. The introductory chapters are devoted to external and internal fixation for fractures, dental implants and replacement of renal function. The following chapters deals with stents and their possible variations, especially the chapters are about esophageal stents, prostatic stents and ureteral stents. The final part of this thesis contains a detailed definition of coronary stents, their functional and shape modifications.

The Possibilities of Accelerating of Ageing process of Brickmaking raw materials mixtures
Lukášková, Monika ; Stančík,, Hynek (referee) ; Sokolář, Radomír (advisor)
Aim of this thesis lies mainly in the verification of how to speed up the time of maturing of brick ceramic mixtures by adding hot water. The theoretical part describes the history of ceramics, brick, ceramic products, manufacture of ceramic brick shards and the time required maturing and its influence on the final properties of ceramic products. In the practical part will be used one type of brick earth and then it will mix a plastic dough, which will be from the current production of mixtures distinguished higher temperature mixing water. Next step is to describe the procedures for tests on individual samples. The outcome of this work should be to evaluate which water temperature is best for shortening the time of maturing brick ceramic mixtures, and what effect this acceleration have on resting of the plastic dough and what is the final characteristics of this sample.

Inveni ipse ubique
Bezarova, Erika ; Vlková, Veronika (referee) ; Klodová, Lenka (advisor)
The diploma thesis maps the author's personal journey to magickal phenomena and experiences with them, which will be mediated through tarot cosmology and interpreted through a spatial map, mainly of ceramic objects, built into the (already completed) game. The work will be grasped partly on a subjective and intuitive principle, and partly on already established working principles relating to tarot and magick. The theoretical part of the work will introduce the work through the description of the objects and the rules of the game, on which the installation of the work will be based.

Pressure sensor made 3D structure
Hanus, Martin ; Pekárek, Jan (referee) ; Kosina, Petr (advisor)
This thesis deals with the points at issue of a 3D structure pressure sensor. The pressure sensor converts pressure into another physical quantity which is easier measure and which is processed subsequently. Usually ways of pressure sensing is for example capacitive, strain-gauge and optical. The 3D structures are constructed through the use of a LTCC technology, which can be laminated to create multi-layer structures, compared to standard high-temperature ceramics. Passive circuit components can be applied onto particular ceramic layers using either thin-layer or thick-layer technology. Practice part of thesis deals with several ways of construction a pressure sensor. First of all capacitive, strain-gauge and optical sensor and possible problems with construction individual sensors above all problems with lamination, cavity or burning

Energy dispersive X-ray spectroscopy of doped PVDF fibers
Smejkalová, Tereza ; Papež, Nikola (referee) ; Sobola, Dinara (advisor)
Tato diplomová práce zkoumá flexibilní materiál k produkci elektřiny založený na piezoelektrickém polymeru Polyvinylidenfluorid (PVDF). Inkorporací piezoaktivní keramiky lze vlastnosti piezoelektrického polymeru PVDF významně zlepšit a převést na užitečnou elektrickou energii. PVDF byl vytvořen elektrostatickým zvlákňováním do vláken o tloušťce 1,5-0,3 µm a poté studován různými analytickými metodami. Tato práce nabízí popis elektrostatického zvlákňování, přípravu vzorků a teoretický úvod do analytických metod, kterým byly vzorky podrobeny. Morfologie a distribuce nanostrukturované keramiky do polymerní matrice PVDF byla pozorována použitím skenovací elektronové mikroskopie (SEM) a energiově disperzní spektroskopie (EDX). Pro tvorbu fáze a podrobné fázové složení byly vzorky charakterizovány infračervenou spektroskopií s Fourierovou transformací (FTIR). Práce také obsahuje analýzu s použitím Ramanovy spektroskopie, metody používané k identifikaci a porovnání chemických sloučenin. Elektrické vlastnosti byly studovány dielektrickou spektroskopií a je poskytnuta korelace se složením. Jednotlivé komponenty dotovaných vláken jsou charakterizovány a vyhodnocovány v souvislosti s jejich budoucím využitím v senzorech.

Development of advanced masonnry blocks for acoustic masonry construction
Lidmilová, Klára ; Horský, Antonín (referee) ; Zach, Jiří (advisor)
This thesis deals with study of sound behaviour in the field of partition structures, especially inter-residential partitions, evaluation of structures in terms of acoustic insulation properties and the production of ceramics in general and acoustic masonry elements. Based on a literature search and market research, new ways of solving acoustic-insulating masonry, including construction, were proposed. The feasibility of construction was verified on a small-scale model created using 3D printing. The selected masonry element was further developed into various dimensional modules, which were compared on the basis of the weights of the individual elements and on the basis of the number of joints. Furthermore, the levels of lightening of the elements were adjusted in order to achieve the highest possible values of the basis weight of the masonry and thus the highest possible airborne sound insulation.
