Structure, dynamics and reactivity of the hydrated electron
Uhlig, Frank ; Jungwirth, Pavel (advisor) ; Pittner, Jiří (referee) ; Sebastiani, Daniel (referee)
Structure, dynamics and reactivity of the hydrated electron Frank Uhlig In this work, one of the products of ionization of water, namely the hydrated electron, has been investigated. The hydrated electron is a key-intermediate in aqueous radiation chemistry. Although known to exist for over 50 years, its structure remained elusive and under discussion up to the present day. We show in this work, that we can obtain a faithful picture of the hydrated electron, its equilibrium structure, dynamics after attachment to water, and its reactivity, using ab initio methods. To this end, small cluster models and extended bulk and slab geometries of water including an excess electron have been investigated.
Effect of Thymine and Cytosine Nucleobase Sequence on the Two-Dimensional Condensation of Pyrimidine Oligodeoxynucleotides at Mercury Surface
Hasoň, Stanislav ; Fojta, Miroslav
The aim of this contribution is study the effect of thymine and cytosine nucleobase composition (different lengths and/or repeat segments of either thymine or cytosine units or their combinations) within a set of the oligodeoxynucleotide (ODN) chains on the two-dimensional of homo- and hetero-pyrimidine ODNs at mercury electrode surface. It was shown that pyrimidine ODNs containing eight and more pyrimidine nucleobases can form, at negatively charged Hg surface (around1.32 V vs. Ag/AgCl), two different 2D condensed films characterized by the differential capacitances of about 9.4 (I-2D) and 7.6 mu F cm(-2) (II2D) respectively.
