The aim of the work is the experimental and theoretical study of properties of molecular semiconductors suitable for optical and electrical applications. The applicant will deal with characterization of physical and chemical properties of studied materials, such as generation and transport of charge carriers, conductivity and photoconductivity, optical absorption, photo- and electroluminescence. The effort will be made to reach reproducibility in preparation of molecular devices and propose the technology for their utilization in organic electronic. The work is a part of large-scale research project funded by EU.
Tutor: Weiter Martin, prof. Ing., Ph.D.
The aim of work is experimental development and characterization of cement binders with special rheology properties. Developed binders will be utilized especially for applications such as shotcrete (shot concrete) with tixotropic behavior and also such as high-fluid self-levelling screeds. The experimental development of binders will result from present knowledge within this branch and student will target the optimalization of composition and processing for achievement of better utility properties. An intergral part of the work will form the explanation and description of the reology effects of the individual binders.
Goal of the dissertation is characterizing of chemical interaction of prospective magnesium alloys, especially in system Mg-Al-Zn. Student will get profound theoretical knowledge in the field electrochemistry of corrosion phenomena as well as practical skill of realization of corrosion experiments and their assessment (microscopy of degraded structure, potentiostatic measurement etc.). Main factors under study will be the alloys composition (especially content of Al), technology of production (gravity and die casting, squeezecasting) and the heat treatments.
Hydrogenated amorphous carbon and its alloys will be prepared in a form of thin film using monomer vapor or a mixture in selected gases by plasma-enhanced chemical vapor deposition (PECVD). Deposited films will be characterized comprehensively by microscopic and spectroscopic techniques to evaluate their physical and chemical properties.

Development of multi-component binders based on portland cement and secondary industrial raw materials and description of nanocrystallizer admixture influence on their utility properties and structure development.
The research within this Ph.D. these will be divided into the branches of particle based, fiber based and combined composites. Various types and combinations of reinforcement in composites based on inorganic matrix will be studied and compared. Works will also include research on composites with alkali activated aluminosilicate matrix. Also the optimal reinforcement of composites, materials, shape and applicability from the viewpoint of corrosion and used binding system will be investigated.
Amorphous materials a-C:H, a-SiC:H a a-SiOC:H in a form of thin film will be studied using spectroscopic ellipsometry. The study is aimed at optical properties of single layers and functional multilayers.
The work will deal with development of composites composed of inorganic cement and organic component. The components selection will be focused on systems which can form mutual binding interactions based on present knowledge especially in the branch of MDF composites. The student will design and prepare composites and aubsequently he will characterize chemical and phase structure of interphase.
Tutor: Zmeškal Oldřich, prof. Ing., CSc.
The topic includes study of optical and electrical properties of biopolymers and other biomaterials. The research will be targeted to the characterization of the possibilities of their application in advanced optoelectronic devices such as sensors. Humic acids and their salts can serve as an example. They play a key role in the soil. With respect to their partly aromatic structure they generate a free radicals after irradiation by UV and VIS light. Other biomaterials and their composites will be studied, the properties will be modified also by nanoparticles.
Scanning probe microscopy will be used to investigate surface properties of plasma polymer films employing contact, noncontact, and semicontact mode. Nanoindentation measurements enable evaluation of near-surface mechanical properties and film adhesion.
Plasma polymer films (interlayers) will be used to surface modify carbon fibers intended as reinforcements for polymer composites. An influence of physical and chemical properties of the deposited interlayer on composite performance will be investigated.
The aim of Ph.D. is to find proper way of contamikned diatomaceous earth modification. An output will be modified diatomaceous earth of properties that are similar to commonly used yet more expansive active admixtures. Implementation of modified diatomaceous earth into building systems and alkali activated systems.
