Downscaling of the contact length Lc of a side-contacted carbon nanotube field-effect transistor (CNTFET) is challenging because of the rapidly increasing contact resistance as Lc falls below 20–50 nm. If in agreement with existing experimental results, theoretical work might answer the question, which metals yield the lowest CNT–metal contact resistance and what physical mechanisms govern the geometry dependence of the contact resistance. However, at the scale of 10 nm, parameter-free models of electron transport become computationally prohibitively expensive. In our work we used a dedicated combination of the Green function formalism and density functional theory to perform an overall ab initio simulation of extended CNT–metal contacts of an arbitrary length (including infinite), a previously not achievable level of simulations. We provide a systematic and comprehensive discussion of metal–CNT contact properties as a function of the metal type and the contact length. We have found and been able to explain very uncommon relations between chemical, physical and electrical properties observed in CNT–metal contacts. The calculated electrical characteristics are in reasonable quantitative agreement and exhibit similar trends as the latest experimental data in terms of: (i) contact resistance for Lc = ∞, (ii) scaling of contact resistance Rc(Lc); (iii) metal-defined polarity of a CNTFET. Our results can guide technology development and contact material selection for downscaling the length of side-contacts below 10 nm.

The crystal structure of a new bismuth-based light-absorbing material for the application in solar cells was determined by single crystal X-ray diffraction for the first time. (CH3NH3)3(Bi2I9) (MBI) is a promising alternative to recently rapidly progressing hybrid organic–inorganic perovskites due to the higher tolerance against water and low toxicity. Single crystal X-ray diffraction provides detailed structural information as an essential prerequisite to gain a fundamental understanding of structure property relationships, while powder diffraction studies demonstrate a high degree of crystallinity in thin films.

A new approach for the fine tuning of flexibility in MOFs, involving functionalization of the secondary building unit, is presented. The "gate pressure" MOF [Zn3(bpydc)2(HCOO)2] was used as a model material and SBU functionalization was performed by using monocarboxylic acids such as acetic, benzoic or cinnamic acids instead of formic acid in the synthesis. The resulting materials are isomorphous to [Zn3(bpydc)2(HCOO)2] in the "as made" form, but show different structural dynamics during the guest removal. The activated materials have entirely different properties in the nitrogen physisorption experiments clearly showing the tunability of the gate pressure, at which the structural transformation occurs, by using monocarboxylic acids with varying backbone structure in the synthesis. Thus, increasing the number of carbon atoms in the backbone leads to the decreasing gate pressure required to initiate the structural transition. Moreover, in situ adsorption/PXRD data suggest differences in the mechanism of the structural transformations: from "gate opening" in the case of formic acid to "breathing" if benzoic acid is used.

We present the synthesis and structural characterization of novel ruthenium complexes containing C^C* cyclometalated N-heterocyclic carbene ligands, η6-arene (p-cymene) ligands and one bridging chlorine ion. Complexes of the general formula [Ru(p-cymene)(C^C*)Cl] were prepared via a one-pot synthesis using in situ transmetalation from the correspondent silver NHC complexes. These complexes react with sodium tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (NaBArF4) to form dinuclear complexes of the general structure [Ru(p-cymene)(C^C*)-μ-Cl-(p-cymene)(C^C*)Ru]+[BArF4]−. Solid-state structures confirm that the pseudo-tetrahedral coordination around the metal center with the η6-ligand aligned perpendicularly to the C^C* ligand and the i-Pr group “atop” is retained in the bimetallic complexes.

Background Critical illness myopathy (CIM) and polyneuropathy (CIP) are a common complication of critical illness. Both cause intensive-care-unit-acquired (ICU-acquired) muscle weakness (ICUAW) which increases morbidity and delays rehabilitation and recovery of activities of daily living such as walking ability. Focused physical rehabilitation of people with ICUAW is, therefore, of great importance at both an individual and a societal level. A recent systematic Cochrane review found no randomised controlled trials (RCT), and thus no supporting evidence, for physical rehabilitation interventions for people with defined CIP and CIM to improve activities of daily living. Therefore, the aim of our study is to compare the effects of an additional physiotherapy programme with systematically augmented levels of mobilisation with additional in-bed cycling (as the parallel group) on walking and other activities of daily living.

Thesis "Transformation of military periodicals since 1989 (for example Obrany lidu and other titles of Naše Vojsko)" discusses the armed services press after 1945, and captures his transformation, inter alia, to reflect changes in the overall social situation during the next decade. The method of work is a historical analysis. This thesis is primarily focused and deals with the establishment of periodicals and the way of state institutions controlling, especially the Ministry of National Defence and the Chief political administration. The aim is to create an overview of army press and, by selected periodicals, to monitor changes occurring during their existence. Attention is also devoted to economic production company - Naše Vojsko (Magnet-Press). This thesis also reflects the transformation of army press which came after the events of November 1989 and which brought a massive reduction in army press. The text is given more attention to newspapers and magazines, the development of more reflective of social change in our country such as in Obrana lidu, Lidová armáda or Československý voják, more narrowly focused than the professional military journals. This thesis uses in addition information from various newspapers and magazines, archival materials from the National Library in Prague,...

The diploma thesis maps the operation of the Bel Mondo lifestylu magazine, which was being published on the Czech market from October 2012 to December 2013. The authors' intentions were to bring a new type of magazine to the Czech market, inspired by foreign print publications such as Intelligent Life, which would combine entertainment with intelligence and present its readers with both original texts and licensed translations from foreign magazines. The thesis introduces the Bel Mondo magazine, puts it into the context of Czech magazine market, describes its operation and searches for reasons that led to its early termination. The theoretical bases for the thesis are gained from expert texts focused on print publishing and magazines. The research part of the thesis focuses on the analysis of thematic and advertising coverage, public response and comments by the editorial staff. The researched data helps to understand the incentive for creation of a new magazine and critically evaluate, whether Bel Mondo really was a unique concept capable of surviving in the Czech media market and whether it had a viable economic model. As the magazine operated under the auspices on the weekly magazine Respekt, the thesis also looks at the degree of interconnection between the two magazines.

Key words: Olympism, Czech Olympic Committee, Children and Youth Olympics, financing of the sports activities, marketing of sports event, publishing

The thesis attends to the mathematical charts constructing of additive triad of pupils on 1st grade of the primary school by means of two mathematical - didactic settings "The Neighbours" and "The Coloured Trio". They occure in mathematical textbooks created by prof. RNDr. Milan Hejný, CSc., RNDr. Darina Jirotková, Ph.D., PhDr. Jana Slezáková, Ph.D. and their colleagues and which are published by Fraus. In my thesis I shall attend to the theoretical pieces of knowledge in the given mathematical area as well as to the reasons for the creation of the new mathematical teaching concept after the czech educational reform. Mathematical tasks from the two appointed settings will be handed in to the pupils to be solved. The pupils will encounter such tasks for the first time. It shall be observed how they are able to cope with the given tasks and if they will be able to infiltrate the problem of the tasks or to invent their own tasks. Further on the thesis shall attend to the means of solutions of similar tasks by the students of The Pedagogical Faculty of the Univerzita Karlova and to the analysis of their comments on the tasks.

The master's thesis Čin magazine in 1929 - 1939 deals with the cultural-political magazine Čin, which was issued in Prague in between the world wars. This left-wing and democratically orientated weekly, later a fortnightly, magazine focused on current cultural and public issues within former Czechoslovakia. The thesis aims to provide a thorough profile of what was an important and distinctive periodical in its time. Firstly, the thesis deals with outlining the notion of the magazine within the mass media, further on it describes the characteristics of the media landscape in the period of the first and second republic, where the printed media and their related area of problems are dealt with in detail. A subchapter on the cultural and political standing of Czechoslovakia in the 20s and 30s of the 20th century is also included, the focus is also on the position of the Čin magazine in the array of magazines of that time. The ensuing parts of the thesis already deal with the periodical itself, firstly in the period from 1929 to 1936, when the magazine was under the leadership of Marie Majerová, and secondly in the period of leadership of Bohumil Přikryl, that is from 1937 to 1939. These separate chapters inform about the publisher of the Čin magazine, the eponymous press and publishing cooperative of...
