Electrochemical Characterization of Self-Assembled Monolayers Containing Redox Switching Element
Nováková Lachmanová, Štěpánka ; Kocábová, Jana ; Vavrek, František ; Sebechlebská, Táňa ; Šebera, Jakub ; Kolivoška, Viliam ; Lukášek, J. ; Balzer, N. ; Valášek, M. ; Hromadová, Magdaléna
Adsorption properties of molecules containing [Ru(terpy)2]2+ and [Os(terpy)2]2+ redox switching element connected to the electrode surface by tripodal thiolate anchoring groups have been studied together with their charge transfer properties in the adsorbed form. STM-based current-voltage measurements confirmed that the conductance of self-assembled monolayer containing [Os(terpy)2]2+ redox switching element is lower than that containing [Ru(terpy)2]2+ element. This observation agrees with previously observed differences in the electron transfer rate constants of these molecules in their adsorbed state.
Electrochemical Characterization of Molecular Conductors Containing Redox Switching Element

Electrochemical properties of new molecules containing tripodal anchor and redox switching\nelement have been studied by cyclic voltammetry and DFT quantum mechanical calculations.\nComparison of their redox properties with individual organometallic [Ru(terpy)2]2+t3+ and\n[Os(terpy)2]2+t3+ redox centers shows that covalently bonded tripodal anchor does not\ncompromise the reversibility of a redox process and has no effect on the stability of new\nmolecules. New molecular conductors have smaller HOMO-LUMO gap and both are oxidized\nat only slightly more positive potentials after tripodal substitution making them suitable for the\ndevelopment of molecular conductors with switching abilities.

Title: Risk capital calculation in invesment life insurance Author: Bc. Tomáš Coufal Department/Institute: Department of Probability and Mathematical Statis- tics Supervisor of the master thesis: Mgr. Josef Lukášek Supervisor's e-mail address: Josef.Lukasek@allianz.cz Abstract: Unit linked insurance is a modern and flexible life insurance product. The last decade was marked by the raising popularity of unit linked insurance. The discussions conserning the impact of the new directive Sol- vency II on the life insurance business focus mainly on the traditional life insurance. This paper examines the issue of the calculation of the risk capital for unit linked insurance. Analysis of the impact of different death guaran- tees, forms of premium payment, time to maturity and dynamic policyholder bahaviour on the risk capital is presented. Keywords: Unit linked insurance, Solvency II, Risk capital, Solvency capital requirement
Investigation of Single Molecule Charge Transport Properties and Geometrical Arrangement in Terpyridine Architectures Supported by the Tetraphenylmethane Tripod

Tripodal platforms were engineered recently to realize a well-defined directional contact between metallic electrodes and molecular architectures dedicated to serve as working elements for electronic applications. In this work we employ cyclic voltammetry, scanning tunneling microscopy break junction technique and theoretical approaches based on the combination of density functional theory and non-equilibrium Green´s function to investigate the geometrical arrangement and single molecule charge transport in terpyridine-based architectures supported by tetraphenylmethane tripod. We demonstrate that this architecture adopts a favorable geometrical arrangement capable of forming highly conductive molecular junctions and is thus suitable to serve as a basis for working molecular switches.

Solvency II
Palátová, Helena ; Marek, Luboš (advisor) ; Lukášek, Josef (referee)
Tato diplomová práce je zaměřená na problematiku nového regulatorního režimu pro oblast pojišťovnictví - Solvency II. Představuje shrnutí současného vývoje a aktuálních dokumentů k této problematice. Cílem práce je představit připravovaný režim a na příkladě se simulovanými daty ukázat rozdíl ve výpočtu solventnosti pro životní pojištění podle stávajícího režimu Solvency I a podle budoucího režimu Solvency II. Práce je rozčleněna do tří hlavních tematických bloků. V první části (druhá a třetí kapitola) je stručný přehled současné situace v oblasti regulace pojistných trhů. Druhá část popisuje obecně navrhovaný režim Solvency II a poslední část obsahuje popis průběhu a výsledků výše zmíněného příkladu.
